[0002] Building construction refers to production activities during the implementation phase of engineering construction, and is the construction process of various types of buildings. During the construction process, support structures are needed. Support is a measure of support, reinforcement and protection for the side walls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. The adjustable support structures currently on the market have the following problems when used.

[0003] The traditional adjustable support structure has low support strength during application, and is usually a single-point support structure. This results in unreasonable distribution of the support point position of the support itself, and the strength of the support cannot be improved. Once the support force of most adjustable support structures becomes loose during application, staff are required to perform maintenance to restore the clamping force. This is not convenient to operate, and is time-consuming and labor-intensive to adjust. It is more troublesome for staff to maintain, and the support frame is more troublesome during installation and disassembly. Utility Model Content
