Concentric and coaxial butt joint construction method for steel pipe column and tool column through foundation pit reverse construction method
The invention relates to the technical field of construction of structural columns and tool columns through a foundation pit reverse construction method, and discloses a concentric and coaxial butt joint construction method for a steel pipe column and a tool column through the foundation pit reverse construction method. The concentric and coaxial butt joint construction method comprises the following steps that S11), pedestals are manufactured, specifically, a form is supported and the pedestals are manufactured according to a position delimited by a butt joint site; a supporting structure is arranged above the pedestals, the supporting structure is provided with an arc-shaped part used for supporting the steel pipe column or the tool column, channel steel is arranged on the two sides of the arc-shaped part, the number and spacing of the pedestals are determined according to the lengths of the steel pipe column and the tool column; and S21), the steel pipe column and the tool column are in butt joint, the steel pipe column and the tool column are hoisted to the supporting structure, the steel pipe column and the tool column are in a concentric and coaxial state, and after one end, provided with a flange, of the steel pipe column and one end, provided with a bolt hole, of the tool column are aligned with each other, preliminary connection is completed through bolts. In the foundation pit reverse construction method, through the butt joint construction method using the pedestals, the axis alignment precision and the butt joint construction efficiency during butt joint of the steel pipe column and the tool column are effectively improved.
本发明涉及基坑逆作法结构柱与工具柱施工技术领域，公开了基坑逆作法钢管柱与工具柱同心同轴对接施工方法，包括以下步骤：S11)台座的制作，根据对接场地划定的位置支模制作台座；台座上方设有支撑结构，支撑结构具有用于支撑钢管柱或工具柱的弧形部，在弧形部的两侧设置槽钢，根据钢管柱及工具柱的长度确定布置台座的数量和间距；S21)钢管柱及工具柱的对接，将钢管柱及工具柱吊运至支撑结构上，使钢管柱与工具柱达到同心同轴的状态，钢管柱设置法兰一端与工具柱设置螺栓孔一端相互对齐后，通过螺栓完成初步连接。在基坑逆作法中，通过使用台座的对接施工方法，有效提高了钢管柱与工具柱对接时轴心对准精度，及对接施工的效率。
