Taiwan is located in an earthquake-prone area, and the damage caused by earthquakes is countless. In order to increase the stability and reliability of buildings and to reduce or avoid casualties and property damage, seismic resistance often needs to be considered when designing construction structures. In addition, when a building is subjected to an excessive impact, the stresses may still cause some damage to the building. Therefore, it is also necessary to consider how to guide the stresses so that the possible damage can be concentrated in the expected areas, thus reducing or avoiding damage to important structures such as the main backbones supporting the building or the intersections of the main backbones such as the welding beads. Furthermore, when damage occurs, it is also expected to develop techniques to make the process of repairing or replacing damaged structural parts easier and faster, thereby extending the life of the building, improving the maintenance effectiveness of the entire building, and reducing or avoiding further expansion of the damage or the spreading of the damage to other structures in the building.

To solve the aforementioned problems, according to one embodiment of the present invention, a construction structure having a replaceable beam-column joint is provided. The construction structure may include a column structure extending along an upright direction and having at least a first side surface, and a beam-column joint which has a joint configuration and a cover plate configuration. The joint configuration may extend along a first direction crossing the upright direction and has a web plate and a first flange. The first flange extends from the first side surface and is connected to a first side edge of the web plate, and the web plate has an end in the first direction fixedly connected to the column structure. The first flange may have a first indentation so as to be divided into a first end section relatively close to the first side surface and a first extension section relatively far away from the first side surface. The cover plate configuration may include a first cover plate extending across the first indentation along the first direction to face and cover the first flange, and the first cover plate may be fixedly connected to the first end section and the first extension section. The first cover plate may have a first neck portion corresponding to the first indentation, and the width of the first neck portion may be smaller than the width of other portions of the first cover plate apart from the first neck portion.

Another embodiment of the present invention provides a replaceable beam-column joint having a joint configuration and a cover plate configuration. The joint configuration may extend along a first direction and may have a web plate and a first flange. The first flange is connected to a first side edge of the web plate, and the first flange may have a first indentation so as to be divided into a first end section and a first extension section. The cover plate configuration may include a first cover plate extending across the first indentation along the first direction to face and cover the first flange, and the first cover plate may be fixedly connected to the first end section and the first extension section. The first cover plate may have a first neck portion corresponding to the first indentation, and the width of the first neck portion may be smaller than the width of other portions of the first cover plate apart from the first neck portion.

Yet another embodiment of the present invention provides a construction structure having a replaceable beam-column joint. The construction structure includes a beam structure extending along a transverse direction and having at least a first surface; and a beam-column joint has a joint configuration and a cover plate configuration. The joint configuration extends along an upright direction crossing the transverse direction and has a web plate and a first flange set. The first flange set extends from the first surface and is connected to a first side edge of the web plate, and the web plate has an end in the upright direction fixedly connected to the beam structure. The first flange set, facing away from the web plate, may sequentially have a first supporting flange, a first side web plate disposed on the first supporting flange, and a first flange disposed on the first side web plate. The cover plate configuration may include a first cover plate extending along the upright direction to cover the first flange. The first cover plate may be fixed onto the first flange and has a first neck portion, and the width of the first neck portion is smaller than the width of other portions of the first cover plate apart from the first neck portion.

According to the embodiments of the present invention, the provided beam-column joint and the construction structure including the same may improve the seismic resistance of an entire building and can reduce or avoid stresses that damage other portions of the construction structure by concentrating the stresses in the expected neck portions. In addition, according to the embodiments of the present invention, when damage occurs at the expect portions of the beam-column joint, the provided beam-column joint and the construction structure including the same may allow for easier replacement of the portions of the damaged beam-column joint to complete the repair of the entire beam-column joint and the construction structure while reducing or avoiding the impact on other structures. Therefore, it can reduce the materials needed to maintain the entire building, accelerate the recovery of the building after earthquakes, extend the service life of the building, and reduce or avoid further damage to the building caused by the damaged structure.

Various embodiments will be described hereinafter, and the spirit and principles of the present invention should be readily understood by those having ordinary skill in the art by reference to the specification and drawings. However, although specific embodiments will be described herein, these embodiments are merely exemplary and are not to be regarded as limiting or exhaustive in any respect. Therefore, to a person having ordinary skill in the art, the changes and modifications to the present invention should be obvious and readily achievable without departing from the spirit and principles of the present invention.

Referring toand, one embodiment according to the present invention discloses a construction structurehaving a replaceable beam-column joint AT. The construction structuremay include a column structure CL extending along an upright direction DT and at least a beam-column joint AT. The beam-column joint AT is connected to at least a side surface, e.g., a first side surface S, of the column structure CL. The beam-column joint AT has a joint configurationand a cover plate configuration. According to some embodiments, the column structure CL may be a column steel structure or a H-shape steel structure, and the beam-column joint AT is a frame made of welded or assembled steel plates. However, the materials and types applicable to different embodiments of the present invention are not limited thereto. The joint configurationmay extend along a first direction Dcrossing the upright direction DT and has a web plateand a first flange W. The web platehas an end in the first direction Dthat can be fixedly connected to (e.g., locked to or welded to) the column structure CL. The first flange Wextends from the first side surface Sand is connected to a first side edge Eof the web platealong the first direction D. The first flange Wmay have a first indentation Fso as to be divided into a first end section Wrelatively close to the first side surface Sand a first extension section Wrelatively far away from the first side surface S.

Continuing with the above, according to the present embodiment, the cover plate configurationcan be matched with the joint configuration. Specifically, the cover plate configurationmay include a first cover plateextending across the first indentation Falong the first direction Dto face and cover the first flange W. The first cover platecan be fixedly connected to (e.g., locked to) the first end section Wand the first extension section W, thereby suspended on the first indentation F. The first cover platemay have a first neck portioncorresponding to the first indentation F, and the width of the first neck portionis smaller than the width of other portions of the first cover plateapart from the first neck portion. In detail, the width of the first neck portionin a second direction Dperpendicular to the first direction Dand the upright direction DT can be relatively shrunk, such that a structure of the first cover platecorresponding to the first neck portionis relatively weakened. Therefore, according to the present embodiment, when an impact such as an earthquake occurs, a stress pressure (e.g., misalignment between beams and columns) to the construction structurecan be correspondingly guided to the first neck portionwhere the structural strength is weakened and below which is the first indentation F, and the first neck portionmay be correspondingly damaged. (e.g., cracked or deformed, etc.). In this way, stress pressure that may be caused to the column structure CL, the joint configurationof the beam-column joint AT, or at which the column structure CL is connected to the joint configuration, or other important structures can be transferred or absorbed to reduce or avoid damage to these structures from the earthquake or the impact.

According to the present embodiment, since the first cover plateis not directly connected to the column structure CL, and below the first neck portion, which is easier to be damaged, is the first indentation F, the impact on the joint configurationis reduced or avoided, and the damage can be relatively guided and limited to the expected portions apart from where the beam-column joint AT is connected to the column structure CL. Therefore, according to some embodiments, depending on the impact level and the damage, it may be possible to correspondingly disassemble only the damaged first cover platefrom the first flange Wto complete the replacement and repair of the construction structureand components of the beam-column joint AT after the impact. As described above, without the need to replace and/or repair the joint configuration, the case of maintenance of the construction structureand the beam-column joint AT after the impact can be increased, and the time and materials consumed to replace and/or repair the construction structureand the beam-column joint AT can be reduced.

Furthermore, according to some embodiments, a similar configuration may be carried out at a second side edge Ein order to further increase the above effect. Specifically, as shown inand, the first side edge Eand the second side edge Emay be opposite to each other in the upright direction DT, and both extend along the first direction D. The joint configurationmay further include a second flange Wextending from the first side surface Sand connected to the second side edge Eof the web plateopposite to the first side edge E. The second flange Walso similarly has a second indentation Fso as to be divided into a second end section Wrelatively close to the first side surface Sand a second extension section Wrelatively far away from the first side surface S. In addition, the cover plate configurationmay further include a second cover plateextending across the second indentation Falong the first direction Dto face and cover the second flange W. As described above, the second cover platecan be fixedly connected to the second end section Wand the second extension section W, thereby suspended on the second indentation F. The second cover platemay have a second neck portioncorresponding to the second indentation F, and the width of the second neck portionmay be smaller than the width of other portions of the second cover plateapart from the second neck portion.

According to the present embodiment, by disposing the second neck portionin a way similar to disposing the first neck portion, the stress pressure is guided and concentrated in the second neck portionand may correspondingly cause damage (such as, but not limited to, cracks and deformations) to the second neck portion, which is not supported by the second flange Wand is narrowed and weakened. In addition, since the damage to the joint configurationand the column structure CL is reduced or avoided, according to the present embodiment, if the second neck portionof the second cover plateis damaged, the replacement and/or repair of the construction structureand the beam-column joint AT can be completed more easily by disassembling and replacing the second cover platefrom the second flange W. Therefore, without the need to replace and/or repair the joint configuration, the case of maintenance of the construction structureand the beam-column joint AT after the impact can be increased, and the time and materials consumed to replace and/or repair the construction structureand the beam-column joint AT can be reduced.

Furthermore, according to some embodiments, in order to make the setup of the first cover plateand the second cover platemore stable, in the construction structureand the beam-column joint AT according to the present embodiment, the cover plate configurationmay further include a first reinforcement plate R, a pair of first intermediate plates U, and a pair of first base plates Ucorresponding to the first cover plate, and may further include a second reinforcement plate R, a pair of second intermediate plates U, and a pair of second base plates Ucorresponding to the second cover plate. According to the present embodiment, the first reinforcement plate Rmay overlappingly cover the first neck portionand be disposed at the surface of the first neck portionfacing away from the first flange W. The second reinforcement plate Rmay overlappingly cover the second neck portionand be disposed at the surface of the second neck portionfacing away from the second flange W. In addition, the pair of first intermediate plates Umay be parallel to the first direction Dand disposed on both sides of the first neck portion, and the pair of first base plates Umay be parallel to the first direction Dand disposed at the first indentation Fto respectively overlap with the pair of first intermediate plates U. Similarly, the pair of second intermediate plates Umay be parallel to the first direction Dand disposed on both sides of the second neck portion, and the pair of second base plates Umay be parallel to the first direction Dand disposed at the second indentation Fto respectively overlap with the pair of second intermediate plates U. In this way, after the first reinforcement plate R, the first intermediate plates U, and the first base plates Uare relatively fixedly connected (e.g., locked), the first neck portioncan be sandwiched and restrained by the first reinforcement plate Rand the first base plates Ualong the upright direction DT, and the first neck portioncan be sandwiched and restrained by the pair of first intermediate plates Ualong the second direction D, thus improving the positioning stability of the first neck portionwhile maintaining the characteristic of a weakened independent structure of the first neck portionby not being directly locked to the first neck portion. Similarly, after the second reinforcement plate R, the second intermediate plates U, and the second base plates Uare relatively fixed (e.g., locked), the second neck portioncan be sandwiched and restrained by the second reinforcement plate Rand the second base plates Ualong the upright direction DT, and the second neck portioncan be sandwiched and restrained by the pair of second intermediate plates Ualong the second direction D, thus improving the positioning stability of the second neck portionwhile maintaining the characteristic of a weakened independent structure of the second neck portionby not being directly locked to the second neck portion.

As described above, the first reinforcement plate Ris fixedly connected to the pair of first intermediate plates Uand the pair of first base plates U, such that the first neck portioncan be sandwiched and restrained between the first reinforcement plate Rand the pair of first base plates Ualong the upright direction DT, and the second reinforcement plate Ris fixedly connected to the pair of second intermediate plates Uand the pair of second base plates U, such that the second neck portioncan be sandwiched and restrained between the second reinforcement plate Rand the pair of second base plates Ualong the upright direction DT, so that the first neck portiondisposed and suspended on the first indentation Fand the second neck portiondisposed and suspended on the second indentation Fcan be further supported and positioned to reduce or avoid misalignment.

Referring toand, according to the embodiments of the present invention, the fixed connection can be realized by various means such as, but not limited to, locking by bolts and nuts relatively through the locking holes. These possible means of fixed connection will not be repeated herein. In addition, according to the present embodiment, the construction structuremay further include a pair of first connecting plates(i.e. a structure of protruding cars) protruding in parallel from the first side surface Sof the column structure CL along the first direction Dand being fixedly connected to or integrally formed with the column structure CL. The side edge of the end of the web platein the first direction Dcan be disposed between the pair of first connecting platesand fixedly connected to the column structure CL by being fixedly connected to (e.g., interlocked to) the pair of first connecting plates. However, according to other embodiments of the present invention, it is also possible to fixedly connect the web plateto the column structure CL directly or indirectly by other means or in conjunction with other means (e.g., welding). Using the first connecting platesto sandwich and lock the web plateas specified herein is merely one embodiment of the present invention and the present invention is not limited thereto.

Next, the exemplary process of constructing a beam-column joint AT and a construction structureincluding the same according to one embodiment of the present invention will be illustrated with reference to.

Referring to, according to the present embodiment, in a construction structure′ that is still being constructed, the beam-column joint AT configured to connect a required beam structure can be constructed on a first side surface Sof the column structure CL, and it should be accordingly understood by those having ordinary skill in the art that the same or similar configuration may also be carried out on other side surfaces of the column structure CL, and it will not be repeated herein. The web plateof the joint configurationcan be correspondingly disposed between parallel first connecting platesconnected to the column structure CL and protruding from the first side surface S. By interlocking using bolts and bolt holes, the joint configurationis fixedly connected to the column structure CL.

Next, referring totogether with, the first cover plateand the second cover platemay respectively cover the first flange Wand the second flange Wof the installed joint configurationin opposite directions. During this process, the first neck portionof the first cover plateis aligned with the first indentation Fof the first flange Wand the first cover plateis locked to the first end section Wand the first extension section Wby using bolts and bolt holes. Similarly, the second neck portionof the second cover plateis aligned with the second indentation Fof the second flange Wand the second cover plateis locked to the second end section Wand the second extension section Wby using bolts and bolt holes.

As shown in, taking the first neck portionas an example, it can be seen that the width TH′ of the first neck portionis smaller than the width THof the main body of the first cover plate, which is fixedly locked to the first flange W. According to some embodiments, the width TH′ of the first neck portionmay allow the first neck portionto at least partially cover the first indentation F. In addition, according to yet some embodiments, the first cover plateand the first flange Wstacked with each other may have the same or similar widths, and the second cover plateand the second flange Wstacked with each other may have the same or similar widths, such that the width of the relatively narrowed first neck portionis smaller than the width of the first indentation Fof the first flange Wand/or such that the width of the relatively narrowed second neck portionis smaller than the width of the second indentation Fof the second flange W. However, the description above is merely exemplary, and other embodiments according to the present invention are not limited thereto.

Next, referring totogether with, a first reinforcement plate Rmay cover the first neck portion, and a pair of first intermediate plates Umay sandwich the first neck portion, and a pair of first base plates Umay be disposed on both sides corresponding to the second direction Dto overlap with the pair of first intermediate plates U, so as to strengthen the positioning accuracy and frame stability of the first neck portion, which may be easily misaligned due to its weakened structure. Similarly, a second reinforcement plate Rmay cover the second neck portion, and a pair of second intermediate plates Umay sandwich the second neck portionand a pair of second base plates Umay be disposed on both sides corresponding to the second direction Dto overlap with the pair of second intermediate plates U, so as to strengthen the positioning accuracy and frame stability of the second neck portion, which may be easily misaligned due to its weakened structure. With this setup, when an impact such as an earthquake occurs, stresses can be guided to concentrate in the expected locations and damage to the beam-column joint AT and the construction structureof other important structures can be reduced or avoided. In addition, based on this framework, even if the first neck portionand/or the second neck portion, or the first reinforcement plate Rand/or the second reinforcement plate Rcorrespondingly assembled are damaged, the repair of the entire beam-column joint AT and the construction structurecan be completed by directly replacing part of or all of the components of the cover plate configuration, thereby reducing or avoiding the disassembling of the joint configuration. Thus, the repair process after earthquakes can be simplified and accelerated, and the materials required for the repair can be reduced.

In the following, some variated embodiments according to the present invention are further described. In these embodiments, only differences from the embodiments described above will be highlighted with reference to; the same or similar details will not be repeated.

Referring to, wherein an exemplary construction process of completing a final construction structurefrom an under-construction construction structure′ is shown, similar to the above described construction process with reference to. According to the present embodiment, there may be a beam-column joint AT′ different from the beam-column joint AT described above. The web plateof the joint configurationof the beam-column joint AT′ may have a recessed portioncorresponding to the first indentation F(or corresponding to the second indentation F), and the recessed portionrecesses relative to a main body′ of the web plate, such that the thickness of the recessed portionin the direction parallel to the width of the first neck portion(e.g., in the second direction D) is reduced. Thus, the structure corresponding to the first neck portionand the second neck portioncan be more weakened, and stresses can be more easily directed to the first neck portionand the second neck portionin response to the thinned recessed portionwhen the structure is subjected to a vibration or an impact. Therefore, the stress pressure can be more easily concentrated in the first neck portionand the second neck portionthan in other areas when the structure is subjected to a vibration or an impact, allowing possible damage to occur in expected locations and reducing or avoiding damage to other important structures.

Next, with reference to the corresponding structural diagram of each component inand the completed structural diagram of each component in, the difference between the construction structureand the beam-column joint AT″ included therein according to yet another embodiment of the present invention and the aforementioned construction structureand the beam-column joint AT included therein is that the first indentation Fand the second indentation Fmay respectively correspond to the edges of the first neck portionand the second neck portionclose to the first side surface S. In detail, as shown in, the first indentation Fand the second indentation Fare not disposed centrally aligned with the first neck portionand the second neck portion, and are relatively skewed toward the first side surface S. The web plateis provided with a pair of slots Grecessed from the two flank faces of the web plateand are aligned with the first indentation Fand the second indentation F, and the web platemay be divided into a connecting portionclose to the first side surface Sand an extension portionaway from the first side surface Swith respect to the pair of slots G. The connecting portionmay be securely fixedly connected to the column structure CL (e.g., may be integrally formed with the column structure CL or welded to the column structure CL) and the connecting portionand the extension portionare further fixedly connected to each other. For example, the construction structuremay further include a pair of first connecting plates, and the pair of first connecting platesare parallel to and respectively disposed corresponding to the two flank faces of the web plate. Therefore, the pair of first connecting platesare respectively across one of the pair of slots Gto be fixedly connected to the web plate, such that the connecting portionand the extension portionof the web plateare disposed between the pair of first connecting plates, and the connecting portionand the extension portionsandwiched between the pair of first connecting platesmay be fixedly connected, for example, by means of indirectly locking through the pair of first connecting plates.

Based on the above framework, according to the present embodiment as compared to the beam-column joint AT and the construction structuredescribed above, since the first indentation Fand the second indentation Fare relatively skewed toward the first side surface Sand are narrower, the first neck portionand the second neck portioncan be at least partially supported by the first flange Wand the second flange W, respectively. Therefore, the support and positioning of the first neck portionand the second neck portioncan be strengthened while realizing the pre-weakened structure of the first neck portionand the second neck portion.

In this state, the cover plate configurationmay merely further include a first reinforcement plate Rand a pair of first intermediate plates U, and a second reinforcement plate Rand a pair of second intermediate plates U. Referring totogether with, the first reinforcement plate Rmay overlappingly cover the first neck portionand be disposed on the surface of the first neck portionfacing away from the first flange W, and the pair of first intermediate plates Uare parallel to the first direction Dand disposed on both sides of the first neck portion. In addition, the second reinforcement plate Rmay overlappingly cover the second neck portionand be disposed on the surface of the second neck portionfacing away from the second flange W, and the pair of second intermediate plates Uare parallel to the first direction Dand disposed on both sides of the second neck portion. With this configuration, the first reinforcement plate Rand the pair of first intermediate plates Umay be fixedly connected, such that the first neck portionmay be sandwiched and restrained between the first reinforcement plate Rand the first flange Walong the upright direction DT, and the second reinforcement plate Rand the pair of second intermediate plates Umay be fixedly connected, such that the second neck portionmay be sandwiched and restrained between the second reinforcement plate Rand the second flange Walong the upright direction DT.

According to the present embodiment, since the first indentation Fis not centrally aligned with the first neck portionand the second indentation Fis not centrally aligned with the second neck portion, damage caused by stress pressure can be reduced or avoided from further expanding along the first neck portionand the second neck portionto the web plate. In addition, even if the center corresponding to the first neck portionand the second neck portioncauses damage to the extension portionof the web plate, since the connecting portionand the extension portionare actually not integrally formed and can be disassembled correspondingly, the replacement or repair of the beam-column joint AT″ and the construction structurecan be completed while reducing or avoiding the disassembly and re-assembly of the connecting portionand the column structure CL.

According to some embodiments of the present invention, the framework disposed corresponding to the column structure CL can be similarly or identically disposed to a beam structure BL (such as, but not limited to, H-shape steel structure or column steel structure). For example, referring to the corresponding framework diagram of each component inand the completed framework diagram of each component in, according to yet another embodiment of the present invention, a construction structurehaving a replaceable beam-column joint BT may include a beam structure BL and a beam-column joint BT. The beam structure BL extends along a transverse direction DH and has at least a first surface S′. The beam-column joint BT has a joint configurationand a cover plate configuration. The joint configurationextends along an upright direction DT crossing the transverse direction DH and has a web plate, a first flange set W, and a second flange set W. The first flange set Wextends from the first surface S′ and is connected to a first side edge Eof the web plate. The second flange set Wextends from the first surface S′ and is connected to a second side edge Eof the web plate.

Specifically, according to the present embodiment, the web platehas an end in the upright direction DT that can be fixedly connected to the beam structure BL. In order to further strengthen the support of the beam structure BL in the upright direction DT, the first flange set Wand the second flange set Wcan be disposed on both sides of the web plate. The first flange set W, facing away from the web plate, can sequentially have a first supporting flange P, a first side web plate Kdisposed on the first supporting flange P, and a first flange Wdisposed on the first side web plate K. Similarly, the second flange set W, facing away from the web plate, can sequentially have a second supporting flange P, a second side web plate Kdisposed on the second supporting flange P, and a second flange Wdisposed on the second side web plate K. In addition, according to some embodiments, in order to increase the connection between the web plateand the first flange set Wand the second flange set Won both sides, a connecting plateextending along the transverse direction DH can be further disposed and fixedly connected through the locking of the connecting plateextending across the web plateto the first flange set Wand the second flange set Won both sides.

Based on the framework described above, according to the present embodiment, the support for the weight of the beam structure BL may be further increased. However, this is merely exemplary, and according to other embodiments, with sufficient support for the beam structure BL, the construction structureand the beam-column joint BT may be respectively disposed only the first flange Wand the second flange Won both sides of the web plate, similar to other embodiments described above, instead of the first flange set Wand the second flange set W. The details of similar kinds will not be repeated herein.

With continued reference to, according to the present embodiment, similar to other embodiments described above, the cover plate configurationmay include a first cover plateand/or a second cover plateextending along the upright direction DT to cover the first flange Wand/or the second flange W. The first cover platemay be fixed onto the first flange Wand have a first neck portion, and the width of the first neck portionis smaller than the width of other portions of the first cover plateapart from the first neck portion. In addition, the second cover platemay be fixed onto the second flange Wand have a second neck portion, and the width of the second neck portionis smaller than the width of other portions of the second cover plateapart from the second neck portion. In addition, the first side web plate Kand the second side web plate Kmay not be directly connected to the beam structure BL or may be merely partially directly connected to the beam structure BL. Therefore, when an impact or a vibration occurs, the relatively structurally weakened first neck portionand the second neck portionmay correspondingly guide or absorb the stress pressure caused by the impact or the vibration (e.g., the stresses of misalignment between beams and columns). In this way, damage may be limited to the expected locations and damage to other important structures may be reduced or avoided. In addition, when damage occurs correspondingly to the first neck portionand the second neck portion, the replacement or repair of the entire beam-column joint BT and the construction structurecan be completed relatively simply by replacing part of or all of the components of the cover plate configuration, thereby simplifying and accelerating the restoration process after earthquakes.

According to some embodiments, the cover plate configurationofmay further include a first reinforcement plate Rand a pair of first intermediate plates Ucorresponding to the first cover plate, and may further include a second reinforcement plate Rand a pair of second intermediate plates Ucorresponding to the second cover plate. The first reinforcement plate Roverlappingly covers the first neck portionand is disposed on the surface of the first neck portionfacing away from the first flange W, and the pair of first intermediate plates Uare parallel to the upright direction DT and disposed on both sides of the first neck portionalong a transverse direction DP. In addition, the second reinforcement plate Roverlappingly covers the second neck portionand is disposed on the surface of the second neck portionfacing away from the second flange W, and the pair of second intermediate plates Uare parallel to the upright direction DT and disposed on both sides of the second neck portionalong the transverse direction DP. In this way, the first reinforcement plate Rand the pair of first intermediate plates Uare fixedly connected, and the second reinforcement plate Rand the pair of second intermediate plates Uare fixedly connected, such that the first neck portionis sandwiched and restrained between the first reinforcement plate Rand the first flange Walong the transverse direction DH, and the second neck portionis sandwiched and restrained between the second reinforcement plate Rand the second flange Walong the transverse direction DH. With this framework, the stability and positioning of the structurally weakened first neck portionand the second neck portioncan be further strengthened, and similar details should be understood with reference to the corresponding descriptions of other embodiments described above, and will not be repeated herein.

In addition, the beam-column joint BT and the construction structureaccording to the present embodiment further include a first supporting platecorresponding to the first cover plate, and a second supporting platecorresponding to the second cover plate. In detail, the end of the first cover plateclose to the first surface S′ may be connected to the first supporting plate(such as, but not limited to, being integrally formed) parallel to the first surface S′ of the beam structure BL, and the end of the second cover plateclose to the first surface S′ may be connected to the second supporting plate(such as, but not limited to, being integrally formed) parallel to the first surface S′ of the beam structure BL. The first supporting platecan be fixedly connected (e.g., locked, but not limited thereto) to the beam structure BL, and the second supporting platecan be fixedly connected (e.g., locked, but not limited thereto) to the beam structure BL. In this way, the support of the beam structure BL can be further strengthened by disposing the first supporting plateand the second supporting plate. In addition, the stability and positioning of the first cover plateand the second cover platecan be further strengthened by the first supporting plateand the second supporting plateintermediately and fixedly connected to the beam structure BL.

Further, according to some embodiments, in the assembled framework shown in, there may be a first gap Mbetween the first flange Wand the first surface S′, and the first supporting platemay be partially inserted into the first gap M. Similarly, there may be a second gap Mbetween the second flange Wand the first surface S′, and the second supporting platemay be partially inserted into the second gap M. In this way, stress pressure transmitted through the beam structure BL may be at least partially reduced or avoided from directly entering into the joint core (e.g., the web plate) of the beam structure BL and the beam-column joint BT, and the possible stress pressure may be at least partially directed into the first cover plateand the second cover platethrough the first supporting plateand the second supporting plateconnected to the beam structure BL. Even if the first cover plateand the second cover plateare damaged (for example, the first neck portionand the second neck portionare damaged), the repair of the beam-column joint BT and the construction structurecan be realized by replacing part of or all of the components of the outer cover plate configurationwhile reducing or avoiding the disassembly and replacement of the framework of the joint core of the beam-column joint BT.

Next, a construction structureand a beam-column joint BT′ included therein according to another embodiment of the present invention will be described with reference to.

The difference between the beam-column joint BT′ and the construction structureaccording to the present embodiment and the aforementioned beam-column joint BT and the construction structureis that the first flange Wmay have a first indentation Fso as to be divided into a first end section Wrelatively close to the first surface S′ and a first extension section Wrelatively far away from the first surface S′. Similarly, the second flange Wmay have a second indentation Fso as to be divided into a second end section Wrelatively close to the first surface S′ and a second extension section Wrelatively far away from the first surface S′. The first neck portionof the first cover platemay be disposed corresponding to the first indentation F, such that the first cover plateextends across the first indentation Fto face and be fixedly connected (e.g., locked) to the first end section Wand the first extension section W. The second neck portionof the second cover platemay be disposed corresponding to the second indentation F, such that the second cover plateextends across the second indentation Fto face and be fixedly connected (e.g., locked) to the second end section Wand the second extension section W.

In addition, according to the present embodiment, it may further include a pair of first base plates Ucorresponding to the first cover plateand disposed at the first indentation F, and a pair of second base plates Ucorresponding to the second cover plateand disposed at the second indentation F, so as to strengthen the positioning and stability of the first neck portionand the second neck portion. These details are similar to other embodiments described above, and will not be repeated herein.

As described above, with the same reference to the descriptions of the beam-column joints AT, AT′, and AT″, the beam-column joint BT′ and the construction structureaccording to the present embodiment can further reduce or avoid additional damage to the first flange Wand the second flange Wwhen the structurally weakened first neck portionand the second neck portionare damaged by the guided stress pressure. In this way, it allows damage to occur at expected locations such as the first neck portionand the second neck portion, and reduces or avoids the need to disassemble and replace the core portion of the beam-column joint BT′, such as the joint configuration, the first flange set W, and the second flange set W, when repairing the beam-column joint BT′ and the construction structure. Therefore, the seismic resistance of the entire beam-column joint BT′ and the construction structurecan be improved, as well as the reparability of damage after the structure is subjected to a vibration and an impact.

In summary, the beam-column joints and the construction structures including the same according to the embodiments of the present invention can enhance the seismic resistance of the entire beam-column joints and the construction structures, and can relatively guide the stress pressure to the expected locations when a vibration or an impact occurs, thereby reducing or avoiding damage to other important structures, such as beam-column intersections. In addition, the beam-column joints and the construction structures including the same according to the embodiments of the present invention can be more easily disassembled for replacement or repair because the structural portions that are more likely to be damaged may be independently separated from the core portion of the beam-column joint or the column structure and the beam structure. In this way, the repair of the entire beam-column joint and the construction structure can be completed more quickly by reducing or avoiding the disassembly of other core portions of the beam-column joint or the column structure and the beam structure, and the materials consumed for the repair can be reduced or avoided. The present invention provides beam-column joints and construction structures including the same with relatively high seismic resistance, repairability, and longevity, thereby reducing or avoiding structural damage and loss of property or even human life that may be brought about by a vibration or an impact.
