Beam-arch combined continuous rigid frame bridge auxiliary support construction device and construction method thereof
The invention relates to a beam-arch combined continuous rigid frame bridge auxiliary support construction device and a construction method thereof. The device supporting frame is fixedly arranged onthe side part of a pier. The support frame is positioned below the lower cantilever beam; the cross beam is transversely and fixedly arranged at the top of the support frame; the two supporting beamsare vertically and fixedly arranged at the tops of the two ends of the cross beam. A distribution beam is fixedly arranged at the top of each supporting beam, the transverse length of each distribution beam is larger than that of the corresponding supporting beam, the multiple supporting blocks are sequentially arranged between the top of each distribution beam and the lower suspension beam at intervals in the transverse direction, and the shape of the top of each supporting block is consistent with that of the bottom of the lower suspension beam. According to the invention, the problems of down-warping deformation and root cracking of the beam body caused by overlarge load borne by the lower chord beam body can be prevented, so that smooth construction is facilitated.
本发明涉及一种梁拱组合连续刚构桥辅助支撑施工装置以及其施工方法。其中的装置支撑架固定设置在桥墩的侧部，支撑架位于下悬梁下方，横梁沿横向固定设置在支撑架的顶部，两个支撑梁沿竖向固定设置在横梁的两端的顶部，每个支撑梁的顶部均固定设置有一个分配梁，分配梁的横向长度尺寸大于支撑梁的横向长度尺寸，多个支撑块沿横向依次间隔设置在每个分配梁的顶部和下悬梁之间，每个支撑块的顶部均和下悬梁的底部形状相一致。本发明可防止下弦梁体承受荷载过大造成的梁体下挠变形、根部开裂的问题，以利于施工的顺利进行。
