本发明涉及一种装配式梁桥或板桥铰缝连接结构，包括装配式梁或板、U形钢筋、L形钢筋、纵向钢筋、短横筋、螺栓和连接钢板。两个螺栓用短横筋焊接，L形钢筋与短横筋焊接，U形钢筋在上下位置焊接在L形钢筋上构成一个钢筋组，预埋若干个钢筋组的两个装配式梁或板对接坐落在连接钢板上并通过预埋的螺栓连接固定，L形钢筋搭接重叠并绑扎固定，纵向钢筋穿过重叠的U形钢筋并与其绑扎固定。其有益效果是：铰缝贯穿梁板桥的整个断面，可解决设计预留伸缩缝易导致底部铰缝混凝土开裂问题，提高铰缝连接质量，连接后的梁(板)桥的整体性好，受力更均匀，承载力增大，铰缝的耐久性增加，提高梁(板)桥的使用寿命。

The invention relates to a novel hinge joint connecting structure of a fabricated beam (plate) bridge. The novel hinge joint connecting structure comprises fabricated beams (plates), U-shaped steel bars, L-shaped steel bars, longitudinal steel bars, short transverse bars, bolts and connecting steel plates. The two bolts are welded through the short transverse bars, the L-shaped steel bars are welded to the short transverse bars, the U-shaped steel bars are welded to the L-shaped steel bars at the upper positions and the lower positions to form a steel bar set, the two fabricated beams (plates)with the multiple steel bar sets embedded are located on the connecting steel plate in a butt joint mode and fixedly connected through the embedded bolts, and the L-shaped steel bars are overlapped,bound and fixed. And the longitudinal reinforcing steel bars penetrate through the overlapped U-shaped reinforcing steel bars and are bound and fixed with the U-shaped reinforcing steel bars. The hinge joint has the advantages that the hinge joint penetrates through the whole section of the beam-slab bridge, the problem that bottom hinge joint concrete is prone to cracking due to reserved expansion joints can be solved, the hinge joint connecting quality is improved, the connected beam (slab) bridge is good in integrity, more uniform in stress, higher in bearing capacity and higher in durability, and the service life of the beam (slab) bridge is prolonged.
