Fabricated truss for large-span cross beam construction and mounting method thereof
The invention discloses a fabricated truss for large-span cross beam construction and a mounting method thereof, and relates to the technical field of bridge construction.The fabricated truss comprises a truss set, the truss set comprises a plurality of trusses arranged in parallel, and the adjacent trusses are connected through a transverse connecting system; the truss comprises a lower chord member, an upper chord member and a plurality of truss web members located between the lower chord member and the upper chord member, and at least two supporting assemblies are arranged at each corner of the bottom of the truss group; wherein the truss web members comprise a plurality of vertical web members and a plurality of inclined web members, two inclined web members are arranged between two adjacent vertical web members to form an inverted M shape, and operating platforms are arranged at the tops, the middles and the bottoms of the vertical web members. According to the assembly type truss, all the rod pieces are connected through bolts or pin shafts, and different trusses can be assembled according to different construction environments; meanwhile, the truss set is high in bearing capacity, and the construction requirement under the plateau gale environment can be met.
本发明公开了一种大跨度横梁施工用的装配式桁架及其安装方法，涉及桥梁施工技术领域，包括桁架组，所述桁架组包括多个平行设置的桁架，且相邻桁架之间通过横向联结系相连，所述桁架包括下弦杆、上弦杆以及多根位于所述下弦杆和所述上弦杆之间的桁架腹杆，所述桁架组的底部的每个角处均设有至少两个支撑组件；其中，所述桁架腹杆包括多根垂直腹杆和多根斜向腹杆，相邻的两根垂直腹杆之间设有两根斜向腹杆以形成倒M形，且所述垂直腹杆顶部、中部和底部均设有操作平台。本申请提供的一种装配式桁架的各杆件之间均为螺栓或销轴连接，可根据不同的施工环境组装不同的桁架；同时，桁架组承载能力强，可以满足高原大风环境下的施工要求。
