Self-locking type connecting structure of composite beam bridge deck slab and construction method of self-locking type connecting structure
The invention discloses a self-locking type connecting structure of a composite beam bridge deck slab and a construction method of the self-locking type connecting structure, and belongs to the technical field of bridge deck slab construction. An upper row and a lower row of parallel self-locking type connecting pieces which are connected in pairs in an anchoring and locking mode in the opposite directions are arranged at the butt joint ends of the two bridge deck slabs in the width direction, and end shear resistance blocks and end shear resistance grooves which extend in the width direction and are matched in the opposite directions are arranged between the upper row of self-locking type connecting pieces and the lower row of self-locking type connecting pieces. The method is suitable for rapid bridge erection, the assembling efficiency of the prefabricated bridge deck can be effectively improved, on-site casting-free, bolt-free and welding-free assembling of the prefabricated bridge deck is achieved, longitudinal steel bars are continuous, the joint area of the bridge deck is not prone to cracking, and certain bending resistance and shear bearing capacity are achieved.
本发明公开了一种组合梁桥面板自锁式连接构造及其施工方法，属于桥面板施工技术领域，连接构造包括两个贯穿有后张预应力束的相对接桥面板，两个所述桥面板的对接端部沿宽度方向设置有上下两排平行且包含若干个相向成对锚锁连接的自锁式连接件，以及上下两排自锁式连接件之间设置有沿宽度方向伸展且相向匹配的端头抗剪块和端头抗剪槽。本发明适用于快速化桥梁架设，能够有效提高预制桥面板装配效率，并且实现了装配式桥面板现场无浇、无栓、无焊、纵向钢筋连续，桥面板接缝区不易开裂，并具有一定抗弯、剪承载能力。
