Combined concrete-filled steel pipe waist beam structure, prefabricated part, connecting joint, and construction method
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to a concrete-filled steel pipe waist beam prefabricated part. The prefabricated part comprises a steel pipe, concrete is filled in the steel pipe, and a hollow part penetrating in the axial direction is arranged in the concrete; a steel reinforcement framework is arranged in the concrete; annular end steel plates are welded to the two ends of the steel pipe and connected with the steel reinforcement framework; and the end steel plates are partially located outside the steel pipe. Expansion connecting steel plates used for being connected with an enclosure structure are welded to the two sides of one face of the steel pipe respectively. The invention further provides a combinedconcrete-filled steel pipe waist beam structure, a connecting joint of the combined concrete-filled steel pipe waist beam structure and a concrete-filled steel pipe support, a construction method of the concrete-filled steel pipe waist beam prefabricated part, and a construction method of the connecting joint of the combined concrete-filled steel pipe waist beam structure and the concrete-filled steel pipe support. The bearing capacity, the deformation resistance, the integrity, the middle joint strength, and the strength of the joint connected with the concrete-filled steel pipe support of the combined concrete-filled steel pipe waist beam can be improved.
本发明属于地下基坑工程技术领域，具体涉及一种钢管混凝土腰梁预制件，包括钢管，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端头钢板，端头钢板与钢筋骨架连接，且端头钢板部分位于钢管外；钢管其中一面的两侧分别焊接有用于与围护结构连接的扩展连接钢板；本发明还提供一种组合钢管混凝土腰梁结构及其与钢管混凝土支撑的连接节点、钢管混凝土腰梁预制件的施工方法以及组合钢管混凝土腰梁结构与钢管混凝土支撑的连接节点的施工方法。本发明能够提高组合钢管混凝土腰梁的承载能力、抗变形能力、整体性、中间节点强度及其与钢管混凝土支撑连接节点的强度。
