Building steel structure column foot installation foundation construction method and joint
The invention discloses a building steel structure column foot installation foundation construction method and a node. The problems that in the prior art, installation and construction are difficult, and installation precision is poor during construction of a steel stand column foot with an inclination angle are solved. Comprising a raft foundation, an anchor rod installation frame, a high-strength anchor rod assembly, a wedge-shaped base plate and a steel stand column, a locking nut, an anchoring end plate, an asbestos base plate, a gasket and a hexagon nut are sequentially installed in a threaded section of the lower end of the high-strength anchor rod from bottom to top, and the wedge-shaped base plate and a spherical nut are sequentially installed at the upper end of the high-strength anchor rod from top to bottom. The spherical nut is in spherical fit with the spherical positioning hole in the wedge-shaped base plate; the high-strength anchor rod is in a prestress tensioning state, and grouting filler is arranged between the high-strength anchor rod and the protection guide pipe. An included angle alpha is formed between the high-strength anchor rod and the vertical direction. The spherical nut is designed at the tensioning end of the high-strength anchor rod, and the installation angle tiny deviation of part of the anchor rod can be adjusted and eliminated through spherical matching.
本发明公开了一种建筑钢结构柱脚安装基础施工方法及节点，用于解决现有技术中对于带有倾斜角度的钢立柱柱脚施工存在的安装难、施工难，以及安装精度差的问题。包括筏板基础、锚杆安装架、高强锚杆组件、楔形垫板和钢立柱，其中，高强锚杆的下端螺纹段自下向上按顺序装入锁定螺母、锚固端板、石棉垫板、垫圈和六角螺母，高强螺杆的上端自上向下按顺序安装楔形垫板和球面螺母，且球面螺母与楔形垫板中的球面定位孔进行球面配合；所述高强锚杆处于预应力拉紧状态，并在该高强锚杆和保护导管之间设有灌浆填充物；且高强锚杆与竖向具有α夹角。通过在高强锚杆张拉端设计球面螺母，该球面配合能调节和消除部分锚杆的安装角度微小偏差。
