Description

Technical Field

[0001] The utility model relates to the field of hexagon socket bolts, in particular to an anti-skid hexagon socket bolt for a steel structure. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Steel components need to be connected and fixed with hexagonal bolts. The hexagonal groove on the head of the hexagonal bolt is very prone to slipping after long-term use and wear. After searching, the prior art (Announcement No.: CN202021611935.0) is a multi-layer anti-slip hexagonal bolt. The article records that "an operating gap is chiseled out on the nut of the bolt body, so that an external hexagonal boss is formed on the nut, and a special tool is set in the operating gap. When operating, the inner and outer wall surfaces of the special tool are in contact with the outer wall surface of the external hexagonal boss and the inner wall surface of the internal hexagonal blind hole in turn, and at the same time, the external hexagon and internal hexagon are combined. The double-layer contact friction effectively reduces the problem of slipping caused by the unilateral friction of the tool on a single hexagonal or internal hexagonal bolt, and solves the problem that ordinary hexagonal or internal hexagonal bolts cannot be removed after wear and slipping. The operation blind hole and cross hole added to the nut allow the bolt body to be disassembled in a variety of ways after slipping, ensuring that the bolt body has the advantage of being removable, fundamentally solving the problem that the bolt cannot be disassembled after slipping and breaking, resulting in the connection equipment being abandoned. However, the anti-slip hexagonal bolts with operation blind holes and cross holes in the prior art are easily oxidized by the outdoor environment, rusted or clogged with impurities in the holes, making it difficult to insert and disassemble special tools.
