Stiffening gusset plate on steel truss girder and welding method
The invention discloses a steel truss girder upper stiffening gusset plate and a welding method, and relates to the technical field of bridge construction, the steel truss girder upper stiffening gusset plate comprises a steel truss girder provided with an upper chord member, and the upper chord member is provided with a welding mechanism; the welding mechanism comprises a plurality of upper welding parts and a plurality of lower welding parts, the upper welding parts are arranged on the upper end face of the upper chord member in parallel in the direction of the steel truss girder, the lower welding parts are arranged on the lower end face of the upper chord member in parallel in the direction of the steel truss girder, and each upper welding part comprises an upper stiffening gusset plate. The method has the beneficial effects that batch manufacturing can be achieved during prefabrication through the welding mechanism and the upper chord member, then the prefabricated upper chord member can be transported to the site in batches, and in the welding process, the minimum stress stage of the connecting position of the upper stiffening gusset plate A and the upper chord member is calculated and determined by means of alternate stress changes of all rod pieces in the pushing process; at the stage, stress at the connecting position of the upper stiffening gusset plate A and the upper chord member is eliminated through a beam jacking and falling measure, and the non-stress state of the welding position is achieved.
本发明公开了一种钢桁梁上加劲节点板及焊接方法，涉及桥梁施工技术领域，包括：设置有上弦杆的钢桁梁，所述上弦杆上设置有焊接机构；所述焊接机构包括多个上焊接部和多个下焊接部，多个所述上焊接部沿钢桁梁方向平行设置在上弦杆上端面，多个所述下焊接部沿钢桁梁方向平行设置在上弦杆下端面，所述上焊接部包括上加劲节点板。本发明的有益效果是：通过焊接机构和上弦杆，实现预制时能分批制造，然后分批运输直现场，在焊接的过程中，利用顶推过程中各杆件应力交替变化，计算确定上加劲节点板A处与上弦杆连接位置应力最小阶段，在该阶段通过顶落梁措施消除上加劲节点板A与上弦杆连接位置应力，达到焊接位置无应力状态。
