Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a prefabricated telescopic scaffolding. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. In existing technologies, scaffolding is generally assembled using steel pipes and couplers. The support height and support range are achieved by increasing or decreasing the number of steel pipes, which is relatively troublesome and labor-intensive. Existing telescopic scaffolding can usually only be extended or retracted in one of the horizontal or vertical directions. When extending or retracting in the vertical direction, due to the limited area of ​​the working platform, if the working platform needs to be expanded, it is generally necessary to build another scaffold. The two scaffolds are set up independently, which is not easy to cross during construction, and the connection is also relatively complicated. Utility Model Content
