This application claims the priority of the Korean Patent Applications NO 10-2024-0039538, filed on Mar. 22, 2024, in the Korean Intellectual Property Office. The entire disclosures of all these applications are hereby incorporated by reference.

The present invention relates to a non-slip safety plate and a method for manufacturing the safety plate, and more specifically, to a non-slip safety plate that effectively prevents a person walking on the surface from slipping, thereby improving safety, and a method for manufacturing the safety plate.

In general, the reinforced concrete method is widely used in construction or civil engineering work, in which the rebar is placed, the formwork is installed, and then the concrete is poured inside the formwork and cured. In this reinforced concrete method, the rebar is exposed until the concrete is poured on the floor, making it difficult to move and there is a risk of slipping, so wooden panels are installed on top to enable workers to move. However, when using these wooden panels, there was a problem of slipping.

To solve this problem, a metal lath, also called mesh-shape plate or expanded metal (EX), having a plurality of rhombus-shaped mesh holesformed as shown inwas used. This plate is made of a mesh-shaped linear bodyformed by forming a plurality of slits in a metal plate and tensioning the slits in the width direction so that they open to form rhombus-shaped mesh holeselongated longitudinally.

However, since the conventional mesh-shape safety plate has a linear bodythat extends only in one direction, forward and backward, as shown in, the linear bodycan prevent the safety plate from slipping in the left-right or side direction to a certain extent when the worker moves, but cannot prevent the safety plate from slipping in the forward and backward direction. Therefore, the problem of safety accidents occurring in which the worker slips and falls while moving while stepping on the safety plate has not yet been resolved.

The present invention is to solve the problems described above, and the object of the present invention is to provide a non-slip safety plate having a solid structure, improved durability, easy manufacturing, and improved safety by preventing a worker from slipping in various directions including the forward, backward and left and right directions of the safety plate while he or she is moving, thereby preventing falls, etc.

According to a feature of the present invention, a non-slip safety plate is provided, which comprises: a plurality of EX mesh sectionsin which a plurality of slits are arranged at regular intervals on a metal plate and the slits are expanded in the width direction to form mesh holeselongated longitudinally, or in which the slits are formed while simultaneously expanding the slits in the width direction to form mesh holes; and a non-slip plate sectionmade of a metal plate and provided between the EX mesh sections, the non-slip plate sectionhaving a plurality of friction protrusionsformed to protrude upward on the upper surface; wherein the non-slip plate sectionis characterized in that it extends long in a longitudinal direction perpendicular to the width direction in which the slits of the EX mesh sectionare expanded and parallel to the elongated mesh holes.

According to another feature of the present invention, a non-slip safety plate is provided, characterized in that the non-slip plate sectionis formed integrally with the EX mesh section.

According to another feature of the present invention, a non-slip safety plate is provided, characterized in that the friction protrusionis formed by the periphery of a perforationprotruding upward formed by punching the bottom surface of a metal plate.

According to another feature of the present invention, a method for manufacturing a non-slip safety plate is provided, characterized by including: a process of forming a plurality of EX mesh sectionsby arranging a plurality of slits at regular intervals on a metal plate so that a plurality of slits are formed in a form of mesh holethat is expanded in the width direction at positions spaced apart from each other in the width direction and expanding the slits in the width direction or simultaneously expanding the slits in the width direction while forming the slits; and a process of forming a non-slip plate sectionby punching the bottom surface of the metal plate so that a plurality of friction protrusionsprotruding upwardly between the plurality of EX mesh sectionsare spaced apart in a length direction perpendicular to the expanded width direction of the mesh hole.

As described above, according to the present invention, by providing a non-slip safety platehaving a plurality of friction protrusionsprovided longitudinally spaced apart between a plurality of EX mesh sectionsspaced apart in the width direction, a worker who steps on the non-slip safety plateand moves is effectively prevented from slipping in various directions including the front-back direction as well as the left-right direction, thereby preventing safety accidents in advance.

And since the EX mesh sectionand the non-slip plate sectionare manufactured as one piece using a single metal plate, they are structurally strong enough to withstand the load of the worker, and thus deformation due to the load is prevented, thereby improving durability. Meanwhile, since the friction protrusionof the non-slip plate sectioncan be manufactured by punching the bottom surface of the metal plate, manufacturing is easy.

The above-described objects, features and advantages of the present invention will become more apparent through the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.

andare drawings illustrating a non-slip safety plate according to an embodiment of the present invention. As illustrated, a non-slip safety plateaccording to an embodiment of the present invention is installed on top of reinforcing bars,arranged at a predetermined interval in the horizontal and vertical directions to form a movement path of a predetermined width on the upper surface thereof, and includes a plurality of EX mesh sectionsand a non-slip plate sectionprovided between the plurality of EX mesh sectionsand having a plurality of friction protrusionsformed thereon.

The above-described plurality of EX mesh sectionsare formed by arranging a plurality of slits at regular intervals on a metal plate and expanding the slits in the width direction to form mesh hole, or by simultaneously expanding the slits in the width direction while forming the slits, to form mesh hole, and are spaced apart in the width direction of the metal plate. At this time, as the slits are opened, a plurality of linear bodiesformed by extending in the length direction are connected at predetermined positions, and a non-slip projectionis formed in a stepped form at the intersections connected in this way to prevent slipping. Accordingly, even if a worker steps on the EX mesh sectionof the non-slip safety plate, slipping in the width left and right direction of the safety plate is prevented. Meanwhile, in order to reinforce the strength of the EX mesh section, reinforcing members may be bonded to the bottom surface, and the EX mesh sectionmay be used not only on the upper portions of rebars,but may also be used in various work sites.

The above non-slip plate sectionis provided between a plurality of EX mesh sections, and a plurality of friction protrusionsprotruding upward are spaced apart from each other on the upper surface. As shown in, the non-slip plate sectionis formed to extend in a length front-back direction perpendicular to the width left-right direction in which the slit of the EX mesh sectionexpands, and a plurality of friction protrusionsare formed spaced apart from each other in the length direction. Accordingly, even if a worker steps on the non-slip plate section, the friction protrusionsprevent the worker from slipping forward, backward, and sideways. Meanwhile, the shape of the friction protrusionscan be formed in various ways.

According to one embodiment of the present invention, the non-slip safety platemay be formed by the peripheral portion of a perforationformed by punching the bottom surface of a metal plate upward so that the friction protrusionof the non-slip plate sectionis formed. As shown in, by punching the bottom surface of the metal plate so as to protrude upward, the peripheral portion of the perforationforms a friction protrusionthat protrudes upward. Meanwhile, the friction protrusionmay be manufactured in various ways other than by punching, but may be easily manufactured through the punching. Meanwhile, the shape of the perforationmay be formed in various ways.

According to one embodiment of the present invention, the non-slip safety platemay be formed integrally with the EX mesh sectionand the non-slip plate section. As shown in, the EX mesh sectionis formed at positions spaced apart from each other in the width direction of a single metal plate, and the non-slip plate sectionis formed between the EX mesh sections, so that the structure is more solid and has superior strength compared to manufacturing them separately and welding them.

A non-slip safety plateaccording to one embodiment of the present invention configured as described above can be manufactured by including a process of forming a plurality of EX mesh sectionsat positions spaced apart from each other in the width direction on a metal plate, and a process of forming a non-slip plate sectionbetween the plurality of EX mesh sections. At this time, it is also possible to manufacture the non-slip plate sectionby forming the EX mesh sectionon both sides in the width direction of the non-slip plate section.

And the process of forming a plurality of EX meshesis as follows: a plurality of slits are arranged at regular intervals in positions spaced apart from each other in the width direction on a metal plate as described above, and the slits are expanded in the width direction or the slits are formed while simultaneously expanding the slits in the width direction, thereby forming a plurality of meshes, and a non-slip projectionis formed at the intersection where a plurality of linear bodiesthat divide the meshesare connected to each other.

And the process of forming the non-slip plate sectionis to form a perforationby punching the bottom surface of the metal plate between a plurality of EX mesh parts, thereby forming a plurality of friction protrusionswith the periphery of the perforationprotruding upward. At this time, the punching is performed so that the perforationsare formed at positions spaced apart along the longitudinal direction of the metal plate.

In this way, when using a safety plate made only of a conventional EX mesh, there was a problem that the worker would slip and fall in the longitudinal front-back direction of the safety plate while moving, but the non-slip safety plateof the present invention is provided with a non-slip plate sectionin which friction protrusionsare spaced apart in the longitudinal direction perpendicular to the width direction in which the slits are expanded between a plurality of EX mesh sections, so that even if the worker steps on the non-slip safety plateand moves, slipping in various directions including the longitudinal front-back direction and the width left-right direction is effectively prevented, thereby preventing safety accidents such as tripping or falling in advance. Meanwhile, the non-slip safety plateof the present invention is not limited to being used by being placed on the arranged reinforcing bars,as illustrated in the drawings, but can be used in various fields such as a painting stepping board.

The present invention described above is not limited to the above-described embodiments and the attached drawings, and it will be apparent to a person skilled in the art to which the present invention pertains that various substitutions, modifications, and changes are possible within a scope that does not depart from the technical spirit of the present invention.
