Connecting structure between top plate and corrugated steel web in bridge cantilever asynchronous construction
The invention discloses a connecting structure between a top plate and a corrugated steel web plate in bridge cantilever asynchronous construction, and particularly relates to a construction measure for reducing stress at the front end of the top plate in corrugated steel web plate cantilever asynchronous construction in the corrugated steel web plate combined bridge cantilever asynchronous construction process. The connecting structure comprises a perforated plate, a rubber ring and an upper flange plate fixed to the top of the web, the perforated plate and the upper flange plate are connected to form a perforated plate connecting piece, and reinforcing steel bars penetrate through holes of the perforated plate. Before concrete pouring of the top plate concrete, the rubber ring is arranged in the foremost end hole of the perforated plate located in the top plate at the end of the cantilever. The characteristic of low rigidity of the rubber ring is utilized; in the cantilever asynchronous construction process, under the condition that the shear strength of the steel and concrete combined surface is not affected, the concrete stress at the front end of the top plate can be effectively reduced, the stress state of the combined part of the corrugated steel web combined bridge in the asynchronous pouring construction process is effectively improved, the safety performance is improved, and the method is suitable for steel and concrete combined structure engineering.
本发明公开一种桥梁悬臂异步施工中顶板与波形钢腹板之间的连接构造，尤其是一种波形钢腹板组合桥梁悬臂异步施工过程中，用于减少波形钢腹板悬臂异步施工顶板前端应力的构造措施。上述连接构造包括开孔板、橡胶圈和固定于腹板顶部的上翼缘板，开孔板与上翼缘板连接形成开孔板连接件，开孔板的孔洞用于穿设钢筋；顶板混凝土浇筑前，在位于悬臂端部顶板内的所述开孔板的最前端孔洞内布设橡胶圈。本发明利用橡胶圈刚度小的特点，在悬臂异步施工过程中，在不影响钢与混凝土结合面抗剪强度的情况下，可有效降低顶板前端混凝土应力，有效改善波形钢腹板组合桥在异步浇筑施工过程中结合部的受力状态，提高安全性能，适用于钢与混凝土组合结构工程。
