Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] 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.TECHNICAL FIELD

[0002] 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.BACKGROUND ART

[0003] 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.

[0004] To solve this problem, a metal lath, also called mesh-shape plate or expanded metal (EX), having a plurality of rhombus-shaped mesh holes 2 formed as shown in FIG. 1 was used. This plate is made of a mesh-shaped linear body 1 formed 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 holes 2 elongated longitudinally.

[0005] However, since the conventional mesh-shape safety plate has a linear body 1 that extends only in one direction, forward and backward, as shown in FIG. 1, the linear body 1 can 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.DISCLOSURETechnical Problems

[0006] 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.Technical Solution

[0007] According to a feature of the present invention, a non-slip safety plate is provided, which comprises: a plurality of EX mesh sections 20 in 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 holes 22 elongated longitudinally, or in which the slits are formed while simultaneously expanding the slits in the width direction to form mesh holes 22; and a non-slip plate section 30 made of a metal plate and provided between the EX mesh sections 20, the non-slip plate section 30 having a plurality of friction protrusions 32 formed to protrude upward on the upper surface; wherein the non-slip plate section 30 is characterized in that it extends long in a longitudinal direction perpendicular to the width direction in which the slits of the EX mesh section 20 are expanded and parallel to the elongated mesh holes 22.

[0008] According to another feature of the present invention, a non-slip safety plate is provided, characterized in that the non-slip plate section 30 is formed integrally with the EX mesh section 20.

[0009] According to another feature of the present invention, a non-slip safety plate is provided, characterized in that the friction protrusion 32 is formed by the periphery of a perforation 31 protruding upward formed by punching the bottom surface of a metal plate.

[0010] 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 sections 20 by 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 hole 22 that 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 section 30 by punching the bottom surface of the metal plate so that a plurality of friction protrusions 32 protruding upwardly between the plurality of EX mesh sections 20 are spaced apart in a length direction perpendicular to the expanded width direction of the mesh hole 22.Advantageous Effect

[0011] As described above, according to the present invention, by providing a non-slip safety plate 10 having a plurality of friction protrusions 32 provided longitudinally spaced apart between a plurality of EX mesh sections 20 spaced apart in the width direction, a worker who steps on the non-slip safety plate 10 and 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.

[0012] And since the EX mesh section 20 and the non-slip plate section 30 are 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 protrusion 32 of the non-slip plate section 30 can be manufactured by punching the bottom surface of the metal plate, manufacturing is easy.DESCRIPTION OF THE DRAWING

[0013] FIG. 1 is a drawing showing an example of a conventional non-slip plate.

[0014] FIG. 2 is a perspective view showing one embodiment of a non-slip safety plate according to the present invention.

[0015] FIG. 3 is a used state view of the above embodiment.DETAILED DESCRIPTION OF THE INVENTION

[0016] 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.

[0017] FIG. 2 and FIG. 3 are drawings illustrating a non-slip safety plate according to an embodiment of the present invention. As illustrated, a non-slip safety plate 10 according to an embodiment of the present invention is installed on top of reinforcing bars 3,4 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 sections 20 and a non-slip plate section 30 provided between the plurality of EX mesh sections 20 and having a plurality of friction protrusions 31 formed thereon.

[0018] The above-described plurality of EX mesh sections 20 are 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 22, or by simultaneously expanding the slits in the width direction while forming the slits, to form mesh hole 22, and are spaced apart in the width direction of the metal plate. At this time, as the slits are opened, a plurality of linear bodies 21 formed by extending in the length direction are connected at predetermined positions, and a non-slip projection 23 is 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 section 20 of the non-slip safety plate 10, 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 20, reinforcing members may be bonded to the bottom surface, and the EX mesh section 20 may be used not only on the upper portions of rebars 3,4 but may also be used in various work sites.

[0019] The above non-slip plate section 30 is provided between a plurality of EX mesh sections 20, and a plurality of friction protrusions 32 protruding upward are spaced apart from each other on the upper surface. As shown in FIG. 2, the non-slip plate section 30 is formed to extend in a length front-back direction perpendicular to the width left-right direction in which the slit of the EX mesh section 20 expands, and a plurality of friction protrusions 32 are formed spaced apart from each other in the length direction. Accordingly, even if a worker steps on the non-slip plate section 30, the friction protrusions 32 prevent the worker from slipping forward, backward, and sideways. Meanwhile, the shape of the friction protrusions 32 can be formed in various ways.

[0020] According to one embodiment of the present invention, the non-slip safety plate 10 may be formed by the peripheral portion of a perforation 31 formed by punching the bottom surface of a metal plate upward so that the friction protrusion 32 of the non-slip plate section 30 is formed. As shown in FIG. 2, by punching the bottom surface of the metal plate so as to protrude upward, the peripheral portion of the perforation 31 forms a friction protrusion 32 that protrudes upward. Meanwhile, the friction protrusion 32 may be manufactured in various ways other than by punching, but may be easily manufactured through the punching 31. Meanwhile, the shape of the perforation 31 may be formed in various ways.

[0021] According to one embodiment of the present invention, the non-slip safety plate 10 may be formed integrally with the EX mesh section 20 and the non-slip plate section 30. As shown in FIG. 2, the EX mesh section 20 is formed at positions spaced apart from each other in the width direction of a single metal plate, and the non-slip plate section 30 is formed between the EX mesh sections 20, so that the structure is more solid and has superior strength compared to manufacturing them separately and welding them.

[0022] A non-slip safety plate 10 according 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 sections 20 at positions spaced apart from each other in the width direction on a metal plate, and a process of forming a non-slip plate section 30 between the plurality of EX mesh sections 20. At this time, it is also possible to manufacture the non-slip plate section 30 by forming the EX mesh section 20 on both sides in the width direction of the non-slip plate section 30.

[0023] And the process of forming a plurality of EX meshes 20 is 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 22, and a non-slip projection 23 is formed at the intersection where a plurality of linear bodies 21 that divide the meshes 22 are connected to each other.

[0024] And the process of forming the non-slip plate section 30 is to form a perforation 31 by punching the bottom surface of the metal plate between a plurality of EX mesh parts 20, thereby forming a plurality of friction protrusions 32 with the periphery of the perforation 31 protruding upward. At this time, the punching is performed so that the perforations 31 are formed at positions spaced apart along the longitudinal direction of the metal plate.

[0025] 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 plate 10 of the present invention is provided with a non-slip plate section 30 in which friction protrusions 32 are spaced apart in the longitudinal direction perpendicular to the width direction in which the slits are expanded between a plurality of EX mesh sections 20, so that even if the worker steps on the non-slip safety plate 10 and 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 plate 10 of the present invention is not limited to being used by being placed on the arranged reinforcing bars 3,4 as illustrated in the drawings, but can be used in various fields such as a painting stepping board.

[0026] 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.

[0017] FIG. 2 and FIG. 3 are drawings illustrating a non-slip safety plate according to an embodiment of the present invention. As illustrated, a non-slip safety plate 10 according to an embodiment of the present invention is installed on top of reinforcing bars 3,4 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 sections 20 and a non-slip plate section 30 provided between the plurality of EX mesh sections 20 and having a plurality of friction protrusions 31 formed thereon.

[0018] The above-described plurality of EX mesh sections 20 are 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 22, or by simultaneously expanding the slits in the width direction while forming the slits, to form mesh hole 22, and are spaced apart in the width direction of the metal plate. At this time, as the slits are opened, a plurality of linear bodies 21 formed by extending in the length direction are connected at predetermined positions, and a non-slip projection 23 is 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 section 20 of the non-slip safety plate 10, 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 20, reinforcing members may be bonded to the bottom surface, and the EX mesh section 20 may be used not only on the upper portions of rebars 3,4 but may also be used in various work sites.

[0019] The above non-slip plate section 30 is provided between a plurality of EX mesh sections 20, and a plurality of friction protrusions 32 protruding upward are spaced apart from each other on the upper surface. As shown in FIG. 2, the non-slip plate section 30 is formed to extend in a length front-back direction perpendicular to the width left-right direction in which the slit of the EX mesh section 20 expands, and a plurality of friction protrusions 32 are formed spaced apart from each other in the length direction. Accordingly, even if a worker steps on the non-slip plate section 30, the friction protrusions 32 prevent the worker from slipping forward, backward, and sideways. Meanwhile, the shape of the friction protrusions 32 can be formed in various ways.

[0020] According to one embodiment of the present invention, the non-slip safety plate 10 may be formed by the peripheral portion of a perforation 31 formed by punching the bottom surface of a metal plate upward so that the friction protrusion 32 of the non-slip plate section 30 is formed. As shown in FIG. 2, by punching the bottom surface of the metal plate so as to protrude upward, the peripheral portion of the perforation 31 forms a friction protrusion 32 that protrudes upward. Meanwhile, the friction protrusion 32 may be manufactured in various ways other than by punching, but may be easily manufactured through the punching 31.

At this time, it is also possible to manufacture the non-slip plate section 30 by forming the EX mesh section 20 on both sides in the width direction of the non-slip plate section 30.

[0023] And the process of forming a plurality of EX meshes 20 is 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 22, and a non-slip projection 23 is formed at the intersection where a plurality of linear bodies 21 that divide the meshes 22 are connected to each other.

[0024] And the process of forming the non-slip plate section 30 is to form a perforation 31 by punching the bottom surface of the metal plate between a plurality of EX mesh parts 20, thereby forming a plurality of friction protrusions 32 with the periphery of the perforation 31 protruding upward.
