Durable web butt joint type prefabricated combined beam bridge and construction method
The invention relates to a durable web butt joint type prefabricated combined beam bridge and a construction method, the durable web butt joint type prefabricated combined beam bridge comprises a prefabricated combined beam, the prefabricated combined beam comprises a steel main beam, and at least one side of the steel main beam is provided with a plurality of transverse shear nails; a bottom-layer bridge deck slab which is fixed with the steel main beams through transverse shear nails; and a top-layer bridge deck slab which is laid on the bottom-layer bridge deck slab. According to the combined beam bridge, the steel consumption in construction can be reduced, meanwhile, the anti-cracking performance of the steel-concrete combined surface is good, the durability of the whole structure isexcellent, and the anti-pulling and anti-shearing performance is high.
本申请涉及一种耐久的腹板对接式预制结合梁桥及施工方法，其包括预制结合梁，所述预制结合梁包括：钢主梁，所述钢主梁的至少一侧设有多个横向剪力钉；底层桥面板，其通过横向剪力钉与钢主梁固定；顶层桥面板，其铺设于底层桥面板上。该结合梁桥能够在节省施工中钢材用量的同时使钢混结合面抗裂性能好、整体结构耐久性优、抗拔和抗剪性能强。
