钢桁梁施工钢桁梁的连接主要采用铆钉连接、栓焊连接和全焊连接。铆接结构中,构件采用铆钉连接,通过铆钉的抗剪传递构件内力;栓焊结构中,构件的板件之间采用焊接,构件与构件之间采用高强度螺栓连接,通过拧紧高强螺栓产生的摩擦力传递构件内力;全焊结构中,构件的板件及构件连接采用焊接连接,通过焊缝传递构件内力。铆钉连接作业中,劳动强度较高,噪音大,在桥梁结构中已较少使用铆接结构;栓焊
Steel truss girder construction of the main steel girder connection using rivets, welded connections and all-welded connection. In the riveted structure, the components are connected by rivets, and the internal force of the components is transmitted through the shearing of the rivets. In the structure of the bolt-welded structure, the welding of the plates of the components adopts high-strength bolts between the components and the components, and the friction generated by tightening the high- Force transmission components internal force; all-welded structure, the components of the plate and components connected by welding connections, components through the welding force transmission components. Rivet connection operations, higher labor intensity, noise, less use in the bridge structure riveting structure; bolt welding
