Non-slip material

Abstract

The present invention provides a slip stopper which achieves a great slip stopping effect, and can be used for a location where a problem occurs if a through hole is opened therein. In a protruding portion 7 that protrudes from the upper surface 5a of a steel plate 5 in the plate thickness direction, a concave portion 8 and drain channels 9 that leads to the steel plate upper surface 5a from this concave portion 8 are formed, and the inner surface of the concave portion 8 and the groove side surfaces of drain channels 9 are formed by shear planes 8a, 9a which face almost perpendicularly to the steel plate upper surface 5a, and are obtained by half blanking that does not open a through hole in the steel plate 5.

Description

technical field [0001] The present invention relates to an anti-slip material used on treads such as floors, pathways, and steps of buildings and construction machines. Background technique [0002] Generally, on the ground or pathways and steps of buildings, as well as on the ground or steps of passenger cars or trucks and special vehicles, etc., especially on decks or platforms of railway vehicles, ships, etc., elevated pads on construction sites, etc. As the anti-slip member with anti-slip function, as such an anti-slip member, existing materials such as those shown in FIG. 12 are known. It is a so-called textured steel plate with a plurality of protrusions 10 forming a continuous pattern on the steel plate. It can achieve corresponding anti-skid effects on ordinary scaffolding. Therefore, reliable anti-slip is required when working at heights on platforms or scaffolding exposed to rain, muddy water, etc., or on construction machinery, when operators use the cover coveri...

Problems solved by technology

[0004] However, when the anti-skid member punched into the aforementioned through hole is directly used on the cover covering the fuselage of a construction machine for example, it will inevitably occur that rainwater or mud will enter the inside of the cover, or the hot wind from the engine will blow to the inside of the cover. To the top of the cover, and the problem of noise diffusion and so on

Therefore, the double structure of fixedly installing common steel plates on the underside of the anti-skid piece can prevent the occurrence of the foregoing problems, but the anti-skid piece of the double structure is compared with the anti-skid piece of the single structure and not only time-consuming but also increases the cost, also exists from the anti-skid piece The problem to be solved by the present invention is that it is difficult to clean when the mud or garbage that enters the through hole is accumulated between the non-slip member and the lower ordinary steel plate or is accumulated in the through hole.
