The present invention relates to a manufacturing method of a nonslip mat for a railway vehicle. The manufacturing method of a nonslip mat for a railway vehicle comprises: a step of alternately locating protruding parts and recessed parts in the surrounding of a circular non-corroded part of a plate by corroding the surrounding of the circular non-corroded part and forming a concave-convex part composed of the protruding and recessed parts to surround the circular non-corroded part; a step of forming a fastening member through hole in the center of the circular non-corroded part and forming a ring-shaped fastening part between the fastening member through hole and the concave-convex part; and a step of expanding a part of the top of the fastening member through hole to be inclined. Therefore, the present invention prevents the plate from getting dirty by preventing foreign materials in the concave-convex part from flowing into the fastening member through hole, and facilitates a fastening member through hole forming work compared with the case of forming the fastening member through hole in the concave-convex part.
본 발명은 따른 철도 차량용 논슬립 매트 제조 방법에 관한 것으로서, 특히 판체 중 원형의 비부식부 주변을 부식시켜 상기 원형의 비부식부 주변에 돌출부와 함몰부가 교대 위치되고, 상기 원형의 비부식부를 둘러싸게 상기 돌출부와 상기 함몰부로 구성된 요철부를 형성하는 단계와, 상기 원형의 비부식부 중앙에 체결부재 관통공을 형성하여 상기 체결부재 관통공과 상기 요철부 사이에 링 형상의 체결부를 형성하는 단계와, 상기 체결부재 관통공의 상부 일부를 구배지게 확장하는 단계를 포함하여, 요철부의 이물질이 체결부재 관통공으로 침투되어 지저분해지는 것을 막을 수 있을 뿐만 아니라, 요철부에 체결부재 관통공을 형성할 경우 보다 체결부재 관통공 형성 작업이 용이한 이점이 있다.
