Bridge floor expansion joint structure and construction method thereof
The invention provides a bridge floor expansion joint structure and a construction method thereof.The bridge floor expansion joint structure comprises grooves formed in the two bridge ends of a joint, pre-embedded ribs are arranged in the grooves, connecting ribs are fixedly arranged at the tops of the pre-embedded ribs, and boundary beams are fixedly arranged at the ends, close to the joint, of the connecting ribs; a waterproof rubber strip is arranged between the two edge beams, a stopping piece corresponding to the joint is arranged in the middle of the lower portion of each edge beam, the top of each stopping piece abuts against the bottom of the corresponding edge beam, a concrete pouring layer is arranged in the corresponding groove, and a surface layer is laid on the top of the bridge. According to the invention, the stop piece is assembled between the top of the joint and the boundary beam, when the stop piece pours concrete into the groove to form a concrete pouring layer, the concrete can be directly poured into the groove without installing a template at the end part of the bridge, and the concrete can be stopped in the groove through the stopping effect of the stop piece, so that the concrete pouring layer is formed. The time for dismounting and mounting the formwork is saved, the construction period can be effectively shortened, and labor and construction cost is reduced.
本发明提供一种桥面伸缩缝构造及其施工方法，桥面伸缩缝构造，包括开设在接缝处两桥梁端部的凹槽，凹槽的内部设置有预埋筋，预埋筋的顶部固定设置有连接筋，连接筋上靠近接缝处的一端固定设置有边梁，两个边梁之间设置有隔水胶条，两个边梁的下方居中设置有与接缝相对应的挡止件，挡止件的顶部与边梁的底部相抵接，凹槽的内部设置有混凝土浇筑层，桥梁的顶部铺设有面层；在本发明中，接缝的顶部与边梁之间装配有挡止件，挡止件在向凹槽内部浇筑混凝土形成混凝土浇筑层时，无需在桥梁端部安装模板，即可直接向凹槽内部浇筑，通过挡止件的阻挡作用，能够将混凝土阻挡在凹槽内部，省去拆装模板的时间能够有效缩短工期，减少人工及施工成本。
