A protection device for anti-painting high-strength bolt holes and a protection method thereof

Abstract

The invention discloses a protection device for anti-painting high-strength bolt holes and a protection method thereof, comprising a combination plate and a back plate respectively arranged on both sides of a component, and fixing bolts are used between the combination plate and the back plate Connected and fixed on the component; the composite board is provided with a longitudinal direction of the composite board for placing the fixing bolt and enabling the bolt head of the fixing bolt and the screw to slide freely inside. A T-shaped slideway; the back plate is provided with a rectangular gap along its length direction, which enables the screw rod of the fixing bolt to freely penetrate; a box cover is provided on the bottom surface of the back plate. The invention has simple structure, flexible and convenient operation, safe and reliable processing process, can be used repeatedly, greatly improves construction efficiency, saves construction cost, ensures on-site painting quality and construction progress, and is especially suitable for steel structure anti-corrosion projects of construction units. In addition, the present invention has relatively low production cost, energy saving and emission reduction.

Description

technical field [0001] The invention relates to building construction, in particular to a protection device for anti-painting high-strength bolt holes and a protection method thereof. Background technique [0002] In the anti-corrosion engineering of steel structures, the surrounding areas of the bolt holes on the components should not be painted. In the past construction, tapes were often used to protect the bolt holes, but the components were easily detached during the overturning and painting process, and the bolt holes could not be effectively protected. , and the torn tapes are discarded at will, affecting the civilized construction on site. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a protection device for anti-painting high-strength bolt holes and a protection method thereof, which are used on both sides at the same time, are easy to operate, ensure quality, are reusable, an...

AI Technical Summary

Problems solved by technology

[0002] In steel structure anti-corrosion engineering, the surroundings of the bolt holes on the components are not allowed to be painted. In the past construction, adhesive tape was often used to protect the bolt holes, but the components are easy to fall off during the turning and painting process, and the bolt hole protection cannot be effectively carried out. , and the torn tape is discarded at will, affecting the civilized construction on site
