Hollow concrete-filled steel pipe support, prefabricated part, construction method, and supporting system
The invention belongs to the technical field of foundation pit engineering, and particularly relates to a hollow concrete-filled steel pipe supporting prefabricated part and a construction method thereof. The hollow concrete-filled steel pipe supporting prefabricated part comprises a steel pipe and a connector steel plate, the steel pipe is filled with concrete, and a hollow part penetrating in the axial direction is arranged in the concrete; a steel reinforcement framework is arranged in the concrete; annular joint steel plates are welded to the two ends of the steel pipe; and the inner sidesof the joint steel plates are connected with the steel reinforcement framework, and the outer sides of the joint steel plates are located outside the steel pipe. The invention further provides a hollow concrete-filled steel pipe support and a supporting system. The hollow concrete-filled steel pipe support is formed by connecting and assembling a plurality of the hollow concrete-filled steel pipesupport prefabricated parts through bolts. The supporting system comprises an enclosure structure, a top beam, a waist beam, and the hollow concrete-filled steel pipe support. The hollow steel pipe concrete supports are supported between the two opposite sides of the top beam and between the two opposite sides of the waist beam. The bearing capacity, the deformation resistance, the integrity, andthe middle joint strength of the hollow steel pipe concrete support can be improved.
本发明属于基坑工程技术领域，具体涉及一种空心钢管混凝土支撑预制件及其施工方法，包括钢管和接头钢板，钢管内填充有混凝土，混凝土内具有沿轴向贯穿的中空部；混凝土内配置有钢筋骨架；钢管的两端均焊接有环形的接头钢板，接头钢板的内侧与钢筋骨架连接，接头钢板的外侧位于钢管外；本发明还提供一种空心钢管混凝土支撑，由多个上述的空心钢管混凝土支撑预制件通过螺栓连接装配而成；本发明还提供一种支撑系统，包括围护结构、冠梁、腰梁和上述空心钢管混凝土支撑；冠梁相对的两侧之间以及腰梁相对的两侧之间均支撑有所述空心钢管混凝土支撑。本发明能够提高空心钢管混凝土支撑承载能力、抗变形能力、整体性以及中间节点强度。
