Novel pre-buried expansion bolt wall connecting piece for fixing cantilever type scaffold

Abstract

The invention provides a novel pre-buried expansion bolt wall connecting piece for fixing a cantilever type scaffold. The novel pre-buried expansion bolt wall connecting piece comprises a steel plate and a foot pad, wherein a vertical bubble column is embedded in the front surface of the steel plate and fixedly connected with the steel plate; a steel pipe is welded and fixed to the center of the right side of the steel plate; second round holes are formed in the positions, close to the four corners, in the steel plate; a screw penetrates through each second round hole and is in sliding connection with the second round hole; and a handle is fixedly connected to the right end of each screw. According to the improved wall connecting piece, expansion nuts are pre-buried in a wall surface, a connecting and fixing mode of pre-buried expansion bolts is adopted, the expansion screws directly penetrate through the steel plate and the foot pad in the later period and are installed in the expansion nuts, the application range is wide, the later repair workload is small, the engineering quality at fixed points is also greatly guaranteed, and no hidden leakage danger exists in the later period.

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, in particular to a novel pre-embedded expansion bolt wall connecting piece for fixing a cantilevered scaffold. Background technique [0002] Construction engineering is the construction of house construction and its ancillary facilities. In the process of house construction, construction workers must use expansion bolts to connect wall parts, which can support scaffolding. At present, the connection and fixation of the attached wall end There are generally the following methods: (1) The tie rods pass through the wall and are fixed on both sides of the wall. This connection and fixing method needs to cut off the tie rods in the later stage. The later repair work is huge and the pre-buried parts of the tie rods are prone to leakage. Hidden dangers; (2) The tie rods pass through the openings of doors and windows, and are fixed on both sides of the wall with cross bars and b...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of pre-embedded expansion bolt wall parts for fixing cantilevered scaffolding. After the traditional outer frame is removed, the repair cost of the existing wall parts attached to the wall ends is high after removal. And it is easy to cause technical problems of leakage hidden danger in the later stage
