Description

Scaffold gangboard fixing method for building construction

Technical Field

The invention relates to the technical field of building construction, in particular to a scaffold gangboard fixing method for building construction.

Background

The scaffold is the work platform who sets up in order to guarantee that each work progress goes on smoothly, can apply to the scaffold often in the building work progress, and the scaffold springboard is the important component part of scaffold, and scaffold springboard hangs between two steel pipes through the form of lock joint usually among the prior art, and this kind of fixed mode is comparatively simple, but it still has following weak point at the in-process of in-service use:

1. corresponding fixed parts are lacked between the end parts of the scaffold gangplank and the steel pipe, so the scaffold gangplank is easy to loosen;

2. when the scaffold gangboard and the steel pipe are lapped, the left and the right of the scaffold gangboard are lack of fixing parts, so the scaffold gangboard is easy to slide left and right along the steel pipe.

Therefore, a scaffold gangboard fixing method for building construction is provided.
