Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a combined scaffolding. Background Art

[0002] A scaffolding is various supports erected at a construction site for workers to operate and solve vertical and horizontal transportation problems. The scaffolding is a general term in the construction industry, referring to places on a construction site such as the exterior wall, interior decoration, or areas with a relatively high floor height where direct construction is not possible. It is mainly used for construction workers to work up and down, or for enclosing the safety net on the periphery and installing components at high altitudes. A prior art indoor scaffolding disclosed in the publication number CN210459925U can split the scaffolding into two groups of side frames and fold them up when not in use or during transfer, reducing the occupied space, having a stronger environmental adaptability, and being stably connected. The standing height of the operator can be adjusted. However, it is fixed by bolts during splitting. Each time of assembly or disassembly, multiple bolts need to be unscrewed separately, and the operation is not convenient and the efficiency is relatively low. Content of the Utility Model
