Large-span steel tube arch bridge closure device and rapid closure method
The invention relates to a large-span steel tube arch bridge closure device and a rapid closure method. A large-span steel tube arch bridge closure device comprises a clamping plate and a plurality of T-shaped connecting plates, all the T-shaped connecting plates are used for being distributed in the circumferential direction of a chord tube at the closure position of an arch bridge at intervals, the T-shaped connecting plates comprise vertical plates and transverse plates, the vertical plates are used for being arranged in the radial direction of the chord tube in the height direction, and the vertical plates are used for being arranged in the axial direction of the chord tube in the length direction; the two ends of the vertical plate are used for connecting two chord pipes needing to be closed, and the clamping plates are used for clamping and connecting the two sides of a splice plate at the bottoms of the two chord pipes needing to be closed. The temporary connection rigidity of the two chord pipes needing to be closed is increased through the longitudinal T-shaped connecting plate, the problem that the rigidity is insufficient before welding of a filling steel pipe at a closing opening is solved, and the situation that the connecting plate is bent and deformed in the closing process is avoided. According to the rapid closure method for the large-span steel tube arch bridge, the closure construction process is reasonably arranged, the closure construction efficiency is improved to the maximum extent, and then the closure precision is improved.
本发明涉及大跨钢管拱桥合龙装置和快速合龙方法。一种大跨钢管拱桥合龙装置，包括夹板和若干T型连接板，所有T型连接板用于沿拱桥的合龙处的弦管的周向间隔分布，T型连接板包括竖板和横板，竖板高度方向用于沿弦管的径向设置，竖板的长度方向用于沿弦管的轴向设置，竖板的两端用于连接需要合龙的两根弦管，夹板用于夹持在需要合龙的两根弦管底部的拼接板的两侧并连接。其通过纵向的T型连接板增加需要合龙的两根弦管的临时连接刚度，解决了合龙口焊接堪补钢管前刚度不足的问题，避免合龙时连接板发生屈曲变形的情况。所述大跨钢管拱桥快速合龙方法，合理安排合龙施工流程，最大限度提高合龙施工的效率，进而提高合龙精度。
