Steel-concrete combined supporting joint structure for foundation pit supporting and construction method of steel-concrete combined supporting joint structure
The invention relates to a steel-concrete combined supporting joint structure shaped like a Chinese character'mi 'and used for foundation pit supporting, and belongs to the technical field of foundation pit excavation. The structure comprises a supporting plate, a bracket, I-shaped steel, an anchor bar pull rod, a main supporting reinforcement cage, a profile steel connecting plate, an H-shaped steel auxiliary support, a wedge-shaped cushion block and concrete. According to construction of the structure, two sets of supporting plates are symmetrically arranged on the two sides of a reinforcement cage, anchor bar pull rods are arranged between the symmetrical supporting plates in a penetrating mode, the anchor bar pull rods penetrate through gaps of annular stirrups of the reinforcement cage, and an approximately octagonal outer contour is defined between the two sets of supporting plates and the reinforcement cage; and meanwhile, the I-shaped steel, the profile steel connecting plates and the H-shaped steel auxiliary supports which are respectively connected and extend along each supporting plate form a shape like a Chinese character'mi ', and then concrete is poured in all spaces within the range of the outer contour, so that the steel-concrete combined supporting node structure which integrates the advantages of a steel supporting structure and a concrete supporting structure and is simple and convenient to construct is formed.
本发明涉及一种用于基坑支护的米字形钢‑混凝土组合支撑节点结构，属于基础坑挖方技术领域。该结构包括支护板、牛腿、工字钢、锚筋拉杆、主支撑钢筋笼、型钢连接板、H型钢副支撑、楔形垫块和混凝土；该结构的施工是两组支护板并对称布置在钢筋笼两侧，并在对称的支护板之间穿设锚筋拉杆，且让锚筋拉杆穿过钢筋笼的环向箍筋的间隙，在两组支护板与钢筋笼之间围成近似八边形的外轮廓；同时沿每块支护板分别联接并延伸的工字钢、型钢连接板和H型钢副支撑形成米字形，再将混凝土浇筑在该外轮廓范围内的所有空间，从而形成兼顾钢支撑结构和混凝土支撑结构优势、且施工简便的钢‑混凝土组合支撑节点结构。
