Connecting structure of concrete bridge deck slab and steel beam and construction method of connecting structure
The invention provides a connecting structure of a concrete bridge deck slab and a steel beam and a construction method of the connecting structure. The steel beams and the bridge deck form a completely connected whole through the welding stud connecting pieces, the notches, the high-strength mortar filler, the grouting holes, the vent holes and the rubber strips. The connecting structure can prevent the joint surface of the concrete bridge deck slab and the steel beam from disengaging, so that shearing force is transmitted continuously, the common stress performance of the concrete bridge deck slab and the steel beam is greatly improved, and the durability of the joint surface is enhanced. Under the condition that prestress needs to be arranged, the problem that arrangement of the prestress steel beams and arrangement of the welding studs need to be considered as a whole can be avoided, and the arrangement difficulty of the prestress steel beams is reduced. The connecting structure has the advantages of being simple in structure, convenient to construct, reasonable in stress and reliable in connection.
本发明提供一种混凝土桥面板与钢梁的连接构造及其施工方法。钢梁与桥面板通过焊钉连接件、槽口、高强砂浆填充料、注浆孔、通气孔、以及橡胶条，形成一个完全连接的整体。该连接构造的设置可避免混凝土桥面板与钢梁的结合面产生脱空的情况，使剪力传递连续，极大改善了两者的共同受力性能，增强了结合面的耐久性能。在需布置预应力的情况下，可避免预应力钢束布置需与焊钉布置统筹考虑的问题，降低了预应力钢束的布置难度。本发明具有结构简单、施工方便、受力合理、连接可靠的优点。
