Expansion joint reinforcement structure for bridge, bridge expansion joint structure and construction method
The invention relates to an expansion joint reinforcement structure for a bridge, a bridge expansion joint structure and a construction method. The expansion joint reinforcement structure comprises amain beam plate, at least one expansion joint construction steel bar set and a plurality of annular stirrups, and a reserved notch is formed in one end of the main beam plate; the expansion joint constructional steel bar sets are arranged at intervals in the transverse bridge direction, one part of each expansion joint constructional steel bar set is implanted into the main beam plate, and the other part of each expansion joint constructional steel bar set is located in the corresponding reserved notch and forms an installation space used for installing the modular expansion joint device; themultiple annular stirrups are arranged in the transverse bridge direction and located on the outer side of the installation space, one part of each annular stirrup is implanted into the main beam plate, and the other part of each annular stirrup is located in the corresponding reserved notch; in all the annular stirrups, the annular stirrup adjacent to the installation space comprises a first section and a second section which are detachably connected; the first section is implanted into the main beam plate, and the second section is located in the reserved notch. The problem in the prior artthat the installation requirement of a large-displacement modular expansion joint and the stress requirement of a beam plate structure in a notch range cannot be met simultaneously can be solved.
本申请涉及桥梁用伸缩缝配筋构造、桥梁伸缩缝结构及施工方法，其包括主梁板、至少一个伸缩缝构造钢筋组和多个环形箍筋，主梁板一端设有预留槽口；伸缩缝构造钢筋组沿横桥向间隔布置，伸缩缝构造钢筋组的一部分植入主梁板内，另一部分位于预留槽口中并形成有用于安装模数式伸缩缝装置的安装空间；多个环形箍筋沿横桥向布置，并位于安装空间外侧，环形箍筋的一部分植入主梁板内，另一部分位于预留槽口中；在所有的环形箍筋中，与安装空间相邻的环形箍筋包括可拆卸连接的第一段和第二段；第一段植入主梁板内，第二段位于预留槽口中。本申请可以解决相关技术中不能既满足大位移量模数式伸缩缝安装需要又满足槽口范围内梁板结构受力要求的问题。
