Problems solved by technology
[0002] The traditional steel trestle generally adopts the form of top-supporting structure. Since the steel pipe piles of this type are welded in parallel to maintain the horizontal integrity, quality control and on-site operation are more difficult. The fabricated steel trestle, in In the assembly process, steel pipe piles are used to set parallel joints at the corresponding positions, which ensures the integrity of the structure and completes the technical optimization in terms of structure. However, when the fabricated steel trestle is built, it needs columns for support, and the columns are placed on the foundation pit. Special fixing devices are required, which cannot be connected with the foundation pit support steel truss, which wastes a lot of resources and costs

The invention discloses a shared system of foundation pit support steel trusses and assembled steel trestle columns, which comprises a fence parapet, horizontal support rods and vertical support rods along the length and width directions of the fence parapet respectively and placed on the foundation pit The upper support frame, the two ports of the horizontal support rod and the vertical support rod are vertically welded with expansion plates, the bottom surface of the horizontal support rod is welded in a matrix with vertical upward limit guide columns, and the horizontal support rod is embedded in the L support plate , the limit guide post is inserted into the guide hole. The foundation pit support steel truss and the prefabricated steel trestle column share the system, the vertical support rods and the horizontal support rods interpenetrate each other, and the arc-shaped side plates and corner support rods support the corners of the fence parapet, so that There will be no dead angle in the support of the foundation pit. Due to the existence of the L support plate, the lateral support rod will be blocked. With the addition of the upper limit guide column inserted into the guide hole, it can also be used in the construction of a prefabricated steel trestle. .
