Prefabricated assembly type steel-concrete composite beam bridge shear connector and construction method
The invention relates to a prefabricated assembly type steel-concrete composite beam bridge shear connector and a construction method, and belongs to the field of civil engineering steel-concrete composite beam bridges. The structure mainly comprises a prefabricated concrete bridge deck slab, I-shaped steel beams, prefabricated double-row Y-shaped perforated steel plates with notches, common steel plates, U-shaped penetrating steel bars, prefabricated top-layer common steel bars with ends, prefabricated bottom-layer common steel bars with ends, hooks, iron rings, iron wires and high-performance grouting materials. The prefabricated double-row Y-shaped steel plates with notches and holes are welded to the I-shaped steel beams, the common steel plates are welded to the two ends of the prefabricated double-row Y-shaped steel plates with the notches and holes, the prefabricated bottom-layer common steel bars with the ends and the U-shaped penetrating steel bars penetrating through the prefabricated double-row Y-shaped steel plates with the notches and holes are hooked tightly through hooks and bound with the prefabricated top-layer common steel bars with the ends through iron wires, and then the prefabricated bottom-layer common steel bars with the ends and the U-shaped penetrating steel bars are welded to the I-shaped steel beams. And finally, grouting materials are poured into the shear grooves of the concrete bridge deck slab. Effective transmission of shearing force between the concrete bridge deck slab and the I-shaped steel beam can be fully guaranteed, and the shearing resistance and the fatigue resistance are good.
本发明涉及一种预制装配式钢‑混组合梁桥抗剪连接件及施工方法，属于土木工程钢‑混组合梁桥领域。其主要包括预制混凝土桥面板、工字钢梁、预制双排Y形带槽口开孔钢板、普通钢板、U形贯穿钢筋、预制顶层带端头普通钢筋、预制底层带端头普通钢筋、弯钩、铁环、铁丝、高性能灌浆料；预制双排Y形带槽口开孔钢板焊接在工字钢梁上，普通钢板焊接在预制双排Y形带槽口开孔钢板两端，预制底层带端头普通钢筋与穿过预制双排Y形带槽口开孔钢板的U形贯穿钢筋用弯钩钩紧，并与预制顶层带端头普通钢筋用铁丝进行绑扎，最后在混凝土桥面板的剪力槽内浇筑灌浆料。本发明能充分保证混凝土桥面板与工字钢梁之间剪力的有效传递，抗剪性能以及抗疲劳性能良好。
