Anti-overturning reinforcing construction method for bridge bent cap
The invention discloses an anti-overturning reinforcing construction method for a bridge bent cap, belongs to the technical field of building reinforcement, and aims to solve the problem that the performance of a steel plate for reinforcing and repairing the bent cap by sticky steel cannot be fully exerted. Firstly, a plurality of chemical anchor bolts are arranged on the two side faces and the two end faces of the cover beam, stiffening rib plates are arranged at the two ends of the cover beam, second steel plates are arranged on the outer sides of the two stiffening rib plates, first steel plates are arranged on the front side and the rear side of the cover beam, and the two second steel plates and the two first steel plates are sequentially connected end to end to form an enclosure plate frame; each chemical anchor bolt on the two end faces of the cover beam is in threaded connection with one tensioning nut, the multiple tensioning nuts are reversely screwed, the tensioning nuts apply pressure to the second steel plate on the same side, then the second steel plate applies tensioning force to the first steel plate, and finally epoxy resin glue is injected between the first steel plate and the cover beam in a pressing mode to form overall structure stress. Due to the fact that the stressed first steel plates on the front side and the rear side of the bent cap generate prestress, the use efficiency of the first steel plates can be greatly improved, and materials are saved.
一种对桥梁盖梁的抗倾覆加固工法，属于建筑加固技术领域，本发明为了解决粘钢加固修复盖梁的钢板性能不能充分发挥的问题。本发明先在盖梁的两侧面和两端面上设置若干化学锚栓，在盖梁的两端设置加劲肋板，在两个加劲肋板的外侧设置第二钢板，在盖梁的前后两侧设置第一钢板，两个第二钢板和两个第一钢板依次首尾相连形成围护板框，盖梁两端面上的每个化学锚栓均与一个张紧螺母螺纹连接，反向旋拧若干张紧螺母，使张紧螺母对同侧的第二钢板施加压力，进而使第二钢板对第一钢板施加张拉力，最终在第一钢板与盖梁之间压注环氧树脂胶，形成整体结构受力。盖梁前后两侧受力的第一钢板由于产生了预应力，可大大提升第一钢板的使用效率，节约材料用量。
