The invention discloses a bridge pre-embedded protection expansion joint structure and a construction method, and relates to the technical field of bridge structures. The structure comprises a hot rolled steel seat used as an expansion joint beam body combination assembly structure and a bridge deck slab used as a bridge deck installation gap filling structure, and the bridge deck slab is fixedlyarranged at the top end of the hot rolled steel seat; edge beams are welded to the four corners of the hot rolled steel seat respectively, and connecting columns penetrate through the middles of the edge beams. According to the structure, the hot rolled steel seat serves as a main structure of the expansion joint device, and anchoring ribs and pressure bearing bases fixed to the inner side of thehot rolled steel seat serve as the transverse load end and the longitudinal load end of the expansion joint structure; through the arrangement of cross beams and pre-embedded steel bars, fastening connection with the section of a bridge is guaranteed; the problems that an existing expansion joint structure is poor in main body strength, large in dependence on an anchoring mechanism assembled in the installation process, low in applicability and not beneficial to expansion joint maintenance in the application stage are solved through the arrangement of the bridge deck slab and a water falling plate on the premise that installation is convenient.
本发明公开一种桥梁预埋防护伸缩缝结构及施工方法，涉及桥梁结构技术领域，结构包括作为伸缩缝梁体结合装配结构的热轧钢座以及作为桥面安装缝隙填补结构的桥面板，桥面板固定设置于热轧钢座顶端，热轧钢座四边角各焊接有一块边梁，边梁中部均贯穿设置有连接柱，该结构以热轧钢座作为伸缩缝装置主体结构，利用其内侧固定有的锚固筋、承压座作为伸缩缝结构的横向、纵向荷载端，其结构通过横梁与预埋钢筋的设置，保证了与桥梁断面的紧固连接，同时利用桥面板与落水板的设置，基于安装方便的前提下，解决了现有伸缩缝结构主体强度较差，对安装时装配的锚固机构依赖大，适用性较低，同时在应用阶段不利于伸缩缝维护的问题。
