Description

a kind of scaffolding

Technical field

The utility model relates to the technical field of scaffolding, and in particular to a scaffold.

Background technique

Currently, exterior wall scaffolding projects are constructed using cantilevered scaffolding. Cantilever scaffolding uses fasteners to connect steel pipes to erect the frame. The frame includes vertical poles, longitudinal horizontal poles, transverse horizontal poles, scaffolding boards, etc.; however, the construction progress of traditional scaffolding is slow and must be carried out one by one. Installing all the fasteners manually is a heavy workload and cumbersome operation. When it comes to high-rise construction, scaffolding needs to be erected at high altitudes. The risk factor during erection is high and the construction is slow. The overall stability of the installed scaffolding is poor. The construction quality of each fastener is difficult to control during erection. The verticality of the pole cannot be guaranteed during erection. The frame itself is a movable system, and the construction quality is difficult to control, which often causes the entire scaffolding to become unstable. Imbalance may lead to engineering accidents and poor practicality, so scaffolding is required.
