Steel-concrete combined inner support prefabricated part, connecting joint structure and construction method
The invention belongs to the technical field of underground foundation pit engineering, and particularly relates to a steel-concrete combined inner support prefabricated part and a construction method. The steel-concrete combined inner support prefabricated part comprises a steel pipe, sealing plates, inner annular plates and outer annular plates, wherein filling concrete is poured in the steel pipe, and a hollow part which penetrates in an axial direction is arranged in the filling concrete; the sealing plates are respectively welded to the end surfaces of both ends of the steel pipe, and theouter annular plate are annularly welded to the outer walls of the both ends of the steel pipe; the inner annular plates are welded to the surfaces, which deviate from the steel pipe, of the sealingplates; and the inner annular plates and the outer annular plates on the same end of the steel pipe are connected through stiffening ribs, and the stiffening ribs are welded with the steel pipe. A connecting joint structure is formed in a way that the outer annular plates and the inner annular plates on the ends of one steel-concrete combined inner support prefabricated part are fixedly connectedwith the inner annular plates and the outer annular plates on the ends of the other steel-concrete combined inner support prefabricated part through a plurality of screws and a plurality of nuts. According to the steel-concrete combined inner support prefabricated part, the bearing capacity, deformation resistance, integrity and intermediate joint rigidity of the steel-concrete combined support can be increased, and the safety of the foundation pit engineering is guaranteed.
本发明属于地下基坑工程技术领域，具体涉及一种钢混组合内支撑预制构件及施工方法，括钢管、封板、内环板和外环板；钢管内浇筑有填充砼，填充砼内具有沿轴向贯穿的中空部；钢管两端的端面均焊接有封板，钢管两端的外壁均环向焊接有外环板；各封板上背离钢管的一面焊接有内环板；位于钢管同一端的内环板与外环板通过加劲肋连接，且加劲肋与钢管焊接；其连接节点结构为通过多根螺杆和多个螺帽将其中一个钢混组合内支撑预制构件端部的外环板和内环板与另一个钢混组合内支撑预制构件端部的内环板和外环板固定连接。本发明能够提高钢混组合支撑的承载能力、抗变形能力、整体性以及中间节点刚度，确保基坑工程安全。
