Protective device for painting-proof high-strength bolt hole and protective method for painting-proof high-strength bolt hole

Abstract

The invention discloses a protective device for a painting-proof high-strength bolt hole and a protective method for the painting-proof high-strength bolt hole. The protective device comprises a composition board and a backboard which are arranged on the two sides of a component correspondingly; the composition board and the backboard are connected through fixing bolts and fixed to the component, the composition board is provided with a T-shaped slide way which penetrating through the composition board in the length direction, used for storing the fixing bolts and capable of enabling bolt end sockets and screw rods of the fixing bolts to freely slide in, and rectangular openings are formed in the backboard in the length direction and capable of enabling the screw rods of the fixing bolts to freely penetrate into; and a box cover is arranged on the bottom face of the backboard. According to the protective device and the protective method, the structure is simple, and operation is flexible and convenient; meanwhile, the machining process is safe and reliable, reuse can be achieved, construction efficiency is greatly improved, the construction cost is saved, the on-site painting quality and construction schedule are ensured, and the protective device is particularly suitable for use of steel structure anti-corrosion engineering of construction units; and additionally, the manufacturing input cost is low, and the energy saving and emission reduction effects are achieved.

Description

technical field [0001] The invention relates to building construction, in particular to a protection device and a protection method for anti-painting high-strength bolt holes. Background technique [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. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a protection device and protection method for anti-painting high-strength bolt holes, which can be used on both sides at the same time, easy to operate, guaranteed in quality, reusable, and strong in sa...
