Description

Scaffolding for construction

technical field

The utility model relates to the field of construction equipment, in particular to a scaffold for construction.

Background technique

Mobile scaffolding is widely used in building decoration and construction because of its advantages of erection, dismantling and simple use. However, due to the simple construction and frequent use of mobile scaffolding, and the height of mobile scaffolding in some construction exceeds 4 meters, workers need to bend over frequently to pick up tools and paint building materials. It is especially easy to cause the hazard of falling from a height. Therefore, the safety protection of mobile scaffolding is particularly important.

In addition, when workers need to move the scaffolding to another place after completing the construction of one wall, because the scaffolding is made of steel pipes, it is heavier and requires the cooperation of many people to move. The universal wheel moves. Although the universal wheel can be stopped by the brake, the wheel surface is slippery and will still move slightly, making the scaffolding less stable.
