Non-slip safety plate and method of manufacturing the same

Abstract

The invention is a non-slip safety plate comprising: a plurality of EX mesh sections 20 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 holes 22 or by simultaneously forming the slits and expanding the slits in the width direction to form mesh holes 22; and a non-slip plate section 30 formed of a metal plate and provided between the EX mesh sections 20 and having a plurality of friction protrusions 32 formed on an upper surface to protrude upward; 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.

1 . 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 . 
     
     
         2 . A non-slip safety plate of  claim 1 , wherein the non-slip plate section  30  is formed integrally with the EX mesh section  20 . 
     
     
         3 . A non-slip safety plate of  claim 1 , wherein 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. 
     
     
         4 . 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 .
