Anti-cracking bridge deck continuous structure and construction method thereof
The invention relates to an anti-cracking bridge floor continuous structure and a construction method thereof.The anti-cracking bridge floor continuous structure comprises a plurality of piers, cover beams fixedly connected to the upper portions of the piers and bridge floor beams erected between every two adjacent cover beams, and a post-cast strip is formed between the end faces of every two adjacent bridge floor beams; the connecting steel bars on every two adjacent bridge floor beams are welded to each other, a plurality of embedded pipes are embedded in the bridge floor beams, one ends of the embedded pipes extend to the lower end faces of the bridge floor beams, the other ends of the embedded pipes protrude out of the end faces, close to the post-cast strip, of the bridge floor beams, and a reinforcing pipe arranged in the post-cast strip is detachably connected between every two opposite embedded pipes. A reinforcing steel rope is arranged on one side of the cover beam, the end of the reinforcing steel rope sequentially penetrates through the embedded pipe of one bridge floor beam, the reinforcing pipe and the embedded pipe of the other bridge floor beam and then is installed on the other side of the cover beam, and a post-pouring concrete layer is poured on the post-pouring belt. The method has the effect of improving the anti-cracking performance of the continuous structure of the bridge.
本申请涉及一种防裂型桥面连续结构及其施工方法，一种防裂型桥面连续结构，包括若干个桥墩、固定连接于桥墩上部的盖梁以及搭设于相邻两个盖梁之间的桥面梁，相邻两个桥面梁的端面之间形成后浇带，相邻两个桥面梁上的连接钢筋相互焊接，所述桥面梁预埋有若干个预埋管，预埋管的一端延伸于桥面梁的下端面，预埋管的另一端凸出于桥面梁靠近后浇带的端面，相对设置的两个预埋管之间可拆卸连接有内置于后浇带的加强管，盖梁的一侧设置有加强钢绳，加强钢绳的端部依次穿设于其中一个桥面梁的预埋管、加强管和另一个桥面梁的预埋管后安装于盖梁的另一侧，后浇带浇筑有后浇混凝土层。本申请具有提高桥梁的连续结构的防开裂性能的效果。
