Fabricated thin-wall concrete filled steel tube pier system and construction process thereof
The invention discloses a fabricated thin-wall concrete-filled steel tube pier system and a construction process thereof. The system comprises a bearing platform, a concrete-filled steel tube column and a prefabricated cover beam. A hollow section is arranged at the upper end of the concrete filled steel tubular column, a positioning end plate is welded to the lower end of the concrete filled steel tubular column, and a plurality of positioning grooves I in the positioning end plate are matched with the positioning screws I. The lower end of the concrete-filled steel tube column is sleeved with column foot encased steel, and the column foot encased steel is filled with concrete. A plurality of anchoring steel bars II and positioning screws II are pre-buried in the lower surface of the prefabricated cover beam, and the prefabricated cover beam is provided with a plurality of reserved through holes. The upper end of the steel pipe concrete column is connected with a positioning outer ring plate, a plurality of positioning grooves II in the positioning outer ring plate are matched with positioning screw rods II, anchoring steel bars II are inserted into the hollow sections, and concrete I is cast into the reserved through holes and the hollow sections of the steel pipes. According to the method, the pier assembly rate is increased, high-quality production of factories and rapid construction on site can be achieved, and on-site wet construction and use of formworks are reduced.
本发明公开了一种装配式薄壁钢管混凝土桥墩体系及其施工工艺，该体系包括承台、钢管混凝土柱和预制盖梁。承台上表面预埋若干锚固钢筋Ⅰ和定位螺杆Ⅰ，钢管混凝土柱上端具有空心段，下端焊接定位端板，定位端板上的若干定位槽Ⅰ与定位螺杆Ⅰ配合。钢管混凝土柱下端套设有柱脚外包钢，柱脚外包钢内填充混凝土。预制盖梁下表面预埋若干锚固钢筋Ⅱ和定位螺杆Ⅱ，预制盖梁具有若干预留通孔。钢管混凝土柱上端连接定位外环板，定位外环板上的若干定位槽Ⅱ与定位螺杆Ⅱ配合，锚固钢筋Ⅱ插入空心段，混凝土一体现浇到预留通孔与钢管的空心段内。本发明提高了桥墩装配率，可实现工厂的高质量生产和现场的快速施工，减少现场湿作业以及模板的使用。
