Plug-in hollow interlayer steel pipe concrete assembly type foundation connecting joint and construction method
The invention provides a plug-in hollow interlayer steel pipe concrete assembly type foundation connecting joint and a construction method. The plug-in hollow interlayer steel pipe concrete assembly type foundation connecting joint comprises an upper flange plate, a lower flange plate, a seamless steel pipe, a bearing platform and a pipe pile, wherein the upper flange plate and the seamless steelpipe are connected with each other; the lower flange plate and the pipe pile are connected with each other; the upper flange plate, the lower flange plate and the seamless steel pipe are all made of steel with the same strength; holes are reserved in the upper flange plate and the lower flange plate; and deformed steel bars penetrating through the holes are pre-buried in the bottom of the upper bearing platform. By the adoption of the plug-in hollow interlayer steel pipe concrete assembly type foundation connecting joint and the construction method, the assembly connection problem of a full-prefabricated pile and a bearing platform anti-pulling foundation is solved, and field welding and concrete pouring are avoided; only several simple procedures are needed on a construction site, the labor cost is greatly reduced, field wet operation is reduced, the fire risk of the construction site is lowered, and the construction speed is increased; and the structure is stable and reliable, the force transmission path is clear, and the safety of the whole structure system is guaranteed.
本发明提供一种插入式中空夹层钢管混凝土装配式基础连接节点及施工方法，包括上法兰盘、下法兰盘、无缝钢管、承台和管桩，上法兰盘和无缝钢管互相连接，下法兰盘和管桩互相连接，上法兰盘、下法兰盘和无缝钢管均由同一强度的钢材组成，上法兰盘和下法兰盘均预留有孔洞，上部承台底部预埋有穿过孔洞的螺纹钢。本发明解决了全预制式桩与承台抗拔基础的装配连接问题，避免了现场焊接和混凝土浇筑；在施工现场只需要几步简单工序，大大减少人工成本，减少现场湿作业和降低施工现场的火灾风险，加快施工速度；而且结构稳定可靠、传力路径明确，保障整体结构体系的安全性。
