Description

Corrosion-resistant and weather-resistant steel structure connecting piece Technical Field The utility model relates to the technical field of steel structure connectors, in particular to an anti-corrosion weather-resistant steel structure connector. Background The corrosion-resistant and weather-resistant steel structure is a steel structure which is made of materials or coatings and has chemical corrosion resistance and weather aging resistance, is mainly used for prolonging the service life in a severe environment, and is most widely applied to bolt connection during assembly at present. The prior art still need add the packing ring through between bolt and the nut when connecting for the protection is not scratched by the nut by the surface of connecting piece, disperses the pressure of nut to being connected piece, however, needs personnel to run through one by one when operating and add, and complex operation therefore proposes an anticorrosive weather-resistant steel structure connecting piece, replaces the packing ring through the rubber structure of addding to reach the abrasionproof effect. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides an anti-corrosion and weather-resistant steel structure connecting piece, which is characterized in that a gasket is replaced by an additionally arranged rubber structure so as to achieve an anti-wear effect. The technical scheme adopted by the utility model for solving the technical problems is that the anti-corrosion weather-resistant steel structure connecting piece comprises a bolt body, a first protecting cover, a first miniature bearing, a nut, a second protecting cover and a second miniature bearing, wherein a first gasket is arranged on the inner side of the first protecting cover, and a first wear-resistant pad is adhered to the bottom surface of the first gasket; And a second gasket is arranged on the inner side of the second protecting cover, and a second anti-wear pad is adhered to the surface of the second gasket corresponding to the position of the first anti-wear pad. By adopting the technical scheme, the nut is matched with the bolt body to achieve the fastening function; The first protecting cover and the second protecting cover the first gasket and the second gasket respectively, and the first gasket and the second gasket are connected to the inner sides of the first protecting cover and the second protecting cover respectively through the first miniature bearing and the second miniature bearing; When the anti-wear protection device is used, the first anti-wear pad corresponding to the bottom of the first protecting cover is in contact with the steel structure through the bolt body, the second anti-wear pad corresponding to the surface of the second protecting cover is in contact with the steel structure through the nut, the first anti-wear pad and the second anti-wear pad are made of polyurethane rubber materials, the anti-wear protection device has the characteristics between rubber and plastic, the strength and durability of the plastic are achieved, and the anti-wear protection device also has the flexibility, high elasticity and good adhesive property of the rubber, so that the anti-wear effect is achieved.
