Novel truss type partition plate for stiffening steel box girder of suspension bridge and operation method of novel truss type partition plate
The invention discloses a novel truss type partition plate for a stiffening steel box girder of a suspension bridge and an operation method of the novel truss type partition plate, and belongs to thetechnical field of bridge design. The novel truss type partition plate comprises an upper transverse rib, a lower transverse rib, inclined struts, gusset plates, stiffening rib plates and high-strength bolts, wherein the upper transverse rib and the lower transverse rib are annularly welded with a top plate, a bottom plate and a web of the stiffening box girder, the gusset plates are arranged at aplurality of nodes of flanges of the upper transverse rib and the lower transverse rib, the adjacent gusset plates are connected through inclined struts, the inclined struts are connected with the gusset plates through high-strength bolts, and a plurality of stiffening rib plates are arranged at key positions of the gusset plates, the upper transverse rib and the lower transverse rib. The invention further provides an operation method of the novel truss type partition plate for the stiffening steel box girder of the suspension bridge. According to the technical scheme, the material utilization rate is high, the weight of the partition plate is greatly reduced, remarkable economic benefits are achieved, all the steel components and the main beam sections are manufactured in a factory together, the steel components are small components, installation and welding are convenient, the construction quality is controllable, the inclined struts and the node plates are connected in a bolted mode, and later maintenance and replacement are convenient.
本发明公开了一种悬索桥加劲钢箱梁新型桁架式隔板及其操作方法，属于桥梁设计技术领域，该产品由上横肋、下横肋、斜撑、节点板、加劲肋板及高强螺栓组成；上横肋、下横肋与加劲箱梁的顶、底、腹板环向焊接，在上横肋、下横肋翼缘若干节点设置节点板，相邻节点板之间通过斜撑相连，斜撑与节点板之间通过高强螺栓连接，节点板及上横肋、下横肋关键位置设置若干加劲肋板。本发明还提供了一种悬索桥加劲钢箱梁新型桁架式隔板的操作方法。本发明的技术方案材料利用率高，大大减轻了隔板重量，有显著的经济效益，所有钢构件和主梁节段一起在工厂内制作完成，钢构件均为小型构件，安装焊接方面，施工质量有可控，且斜撑与节点板采用栓接，后期维护更换方便。
