Detachable steel-concrete composite bridge complete-set bolt shear connector and construction method of detachable steel-concrete composite bridge complete-set bolt shear connector
The invention discloses a detachable steel-concrete composite bridge complete-set bolt shear connecting piece and a construction method thereof.The connecting piece comprises a plurality of bolts connected to a steel beam and a plurality of embedded parts embedded in a prefabricated concrete bridge deck slab, and each embedded part comprises an upper steel plate, a lower steel plate and a plurality of round steel pipes connected between the upper steel plate and the lower steel plate; and after the bolt penetrates through the embedded part, the steel base plate is mounted and the nut is screwed. The prefabricated concrete bridge deck slab and the steel beam of the steel-concrete composite bridge can be detachable, later use and maintenance are facilitated, wet operation of the concrete bridge deck slab can be greatly reduced, stressed steel bars can also penetrate through and be continuous, and the construction efficiency is improved. Full prefabrication of the concrete bridge deck slab is basically achieved, and the overall stress performance of a shear-resistant connecting area of the concrete bridge deck slab is facilitated.
本发明公开了一种可拆卸钢混组合桥梁成套螺栓剪力连接件及其施工方法，该连接件包括连接在钢梁上的若干螺栓和预埋在预制混凝土桥面板内的若干预埋件，预埋件包括上部钢板和下部钢板以及连接在两者之间的若干圆形钢管，螺栓穿过预埋件后安装钢垫板并旋紧螺母。本发明能实现钢混组合桥梁的预制混凝土桥面板和钢梁的可拆卸，便于后期的使用维护，还能大量减小混凝土桥面板的湿作业，受力钢筋也能贯通连续，基本实现了混凝土桥面板的全预制且有利于混凝土桥面板抗剪连接区域的整体受力性能。
