Fabricated swivel bridge
The invention discloses a fabricated swivel bridge, which belongs to the technical field of bridge construction and comprises bridge bodies, a prefabricated connecting plate is mounted between two adjacent bridge bodies, supporting positions are arranged at two ends of each bridge body, and the two adjacent bridge bodies form a T-shaped closure gap matched with the prefabricated connecting plate through the supporting positions. A pouring groove is formed in the prefabricated connecting plate, a plurality of sliding holes communicated with the pouring groove are formed in the side, close to the bridge body, of the prefabricated connecting plate, connecting columns which are spirally arranged are installed in the sliding holes in a sliding mode, reinforcing steel bars are installed in the connecting columns, and connecting holes matched with the connecting columns are formed in the bridge body. By arranging the spiral connecting columns, when concrete is poured, it is guaranteed that the sliding holes and the connecting holes can be filled with the concrete, and the situation that gaps exist in the sliding holes and the connecting holes due to direct pouring, and consequently the structural stability is affected is avoided; the reinforcing steel bars are arranged in the connecting column, and corrosion or bending caused by the fact that the reinforcing steel bars are exposed in the construction process is avoided.
本发明公开了一种装配式转体桥梁，属于桥梁施工技术领域，包括：桥梁本体，相邻两个桥梁本体之间安装有预制连接板，所述桥梁本体两端设有支撑位，相邻两个桥梁本体通过支撑位形成T形的与预制连接板配合的合拢间隙，所述预制连接板上设有浇筑槽，所述预制连接板靠近桥梁本体侧设有多个与浇筑槽连通的滑孔，所述滑孔内滑动安装有呈螺旋设置的连接柱，所述连接柱内安装有钢筋，所述桥梁本体上设有与连接柱配合的连接孔。本发明通过设置螺旋状的连接柱，使浇筑混凝土时，保证了混凝土能够填满滑孔和连接孔，避免直接浇筑造成滑孔和连接孔内部存在间隙，而影响结构稳定性；钢筋设置在连接柱内部，避免施工过程中，钢筋裸露在外造成的腐蚀或弯曲。
