Concrete-filled steel tube pile-column integrated structure and construction method
The invention discloses a concrete-filled steel tube pile-column integrated structure and a construction method. Threads are welded to the outer wall of a steel tube of a concrete-filled steel tube pile, the lower end of the pile is manufactured into a pointed cone shape according to design requirements, the pile is screwed into a foundation in the mode that matched equipment applies axial force and torque to the top of the pile at the same time, an outer sleeve is connected with the pile in a lower structure and a column in an upper structure through threaded connection at the position of the connecting portion of the pile and the column, all components of the pile-column integrated construction are prefabricated in a segmented mode, and mechanical installation is achieved. The position of the connecting portion of the pile and the column is generally subjected to large bending moment and is a weak link, the pile-column integrated connection has important engineering significance, secondary connection between piles and columns is avoided, the construction period is shortened, and the technical advantages are obvious.
本发明公布了钢管混凝土桩柱一体式结构及施工方法，在钢管混凝土桩的钢管外壁焊接螺纹，桩下端根据设计要求制成尖圆锥形，通过配套设备在桩顶同时施加轴力和扭矩的方式将桩旋进入地基，在桩柱连接部位所处位置，通过螺纹连接将外套管连接下部结构中的桩和上部结构中的柱，桩柱一体式施工各部件分节预制完成，机械化安装。桩柱连接部分所处位置一般由于受到的弯矩大，是薄弱环节，桩柱一体式连接具有重要的工程意义，且避免了桩柱之间的二次连接，缩短了施工周期，技术优势明显。
