Dangerous old bridge transformation construction method
The invention relates to the field of dangerous old bridge transformation construction methods, in particular to a dangerous old bridge transformation construction method. The dangerous old bridge comprises at least two T-shaped beams in the transverse direction of the bridge, the construction method comprises the following steps that S1, a hanging bracket construction platform is erected below the T-shaped beams, the hanging bracket construction platform is hung on the bridge floor T-shaped beams through a plurality of first flexible ropes, in the transverse direction of the T-shaped bridge, the projections of the adjacent first flexible ropes connected to the same T-shaped beam in the longitudinal direction of the T-shaped bridge form an included angle A, and A is larger than 0 degree and smaller than 90 degrees; and S2, T-beam reinforcing construction and bridge support (3) replacement construction are conducted based on the hanging bracket construction platform. According to the transformation construction method for the dangerous old bridge, flexible connection between the hanging bracket construction platform and the T-shaped beam is converted into connection close to rigidity, and the stability of the hanging bracket construction platform in the transverse direction of the T-shaped bridge is well guaranteed; the connecting mode of the hanging bracket construction platform and the T-shaped beam can meet the use requirement of the hanging bracket construction platform serving as a construction platform for reinforcing the T-shaped beam.
本发明涉及危旧桥改造施工方法领域，特别涉及一种危旧桥改造施工方法。危旧桥包括沿桥横向的至少两个T梁，该施工方法包括如下步骤：S1：在T梁下方搭设吊架施工平台，吊架施工平台通过若干第一柔性绳悬吊在桥面T梁上，在沿T桥横向上，连接于同一T梁的相邻第一柔性绳在沿T桥纵向上的投影具有夹角A，0°＜A＜90°；S2，基于吊架施工平台进行T梁加固施工和桥梁支座(3)更换施工。本申请的危旧桥改造施工方法，将吊架施工平台与T梁之间的柔性连接转化为接近刚性的连接，很好地保证了吊架施工平台在沿T桥横向上稳定性，吊架施工平台与T梁的连接方式能够满足吊架施工平台作为用于加固T梁的施工平台的使用需要。
