Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a lifting device for construction. Background Art

[0002] Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly used in exterior walls, interior decoration or places with high floors that cannot be directly constructed. It is mainly used for construction workers to work up and down or for the maintenance of external safety nets and the installation of components at high altitudes. It is usually made of bamboo, wood, steel pipes or synthetic building materials.

[0003] When renovating old houses or building new ones, scaffolding needs to be built outside the foundation or on the outer wall of the building. Construction workers transport the transported building materials to the building on the scaffolding (they can also work up and down). In urban villages and rural areas, the buildings are not high, and the scaffolding is generally made of bamboo, wood, and a small amount of steel pipes. Since the erection of scaffolding is relatively cumbersome, the traditional bamboo and wood building materials are low in safety, and replacing all the components with steel building materials will increase the transportation burden, increase the difficulty of erection, and increase the erection cost, which needs to be improved.
