Truss type steel tube arch bridge centering closure structure and construction method
The invention discloses a truss-type steel tube arch bridge centering closure structure and a construction method, and belongs to the technical field of steel tube arch bridge closure. The truss-type steel tube arch bridge centering closure structure comprises main chord tubes, stiffening plates, positioning frames, nuts and screws; the reinforcing plates are annularly welded to the inner walls of the two main chord pipes which are arranged in an aligned mode respectively, the pair of positioning frames are welded to the reinforcing plates on the two sides respectively, the pair of nuts are installed in the two positioning frames respectively, and the two ends of the screw are in threaded connection with the two nuts respectively. Dynamic adjustment can be conducted according to the local air temperature, observation is convenient, the closure installation quality is improved, alignment is accurate, the welding quality is high, and the safety of the overall structure after closure is guaranteed.
本发明公开一种桁架式钢管拱桥对中合龙结构及施工方法，属于钢管拱桥合龙技术领域，包括：主弦管、加劲板、定位框、螺母和螺杆；多个所述加劲板环状分别焊接在对位设置的两个所述主弦管内壁上，一对所述定位框分别焊接在两侧的多个所述加劲板上，一对所述螺母分别安装在两个定位框中，所述螺杆的两端分别与两个所述螺母螺纹连接。本发明可根据当地气温进行动态调整，便于观察，提高合龙安装质量，精准对位，焊接质量高，保证合龙后整体结构的安全性。
