Power transmission line iron tower folded chord cross arm
The invention discloses a power transmission line iron tower folded chord cross arm. The power transmission line iron tower folded chord cross arm comprises two trusses, first reinforcing ribs and second reinforcing ribs. The two trusses are of a net-shaped structure, the outer contour of each truss is in a folded-line-shaped divergence shape from one point to the two sides in a centralized mode,the two trusses are oppositely arranged, the centralized ends of the two trusses are connected with each other, a gap is formed between the divergence ends, and the first reinforcing ribs and the second reinforcing ribs are correspondingly arranged between the two opposite sides of the two trusses. The power transmission line iron tower folded chord cross arm has the advantages that for a steel structure cross arm mainly bearing tension load of a guide wire and a ground wire, and compared with a traditional cross arm, the cross arm can enable internal force distribution of cross arm main materials to be more uniform and reasonable; and meanwhile, the stress level of a cross arm member can be lowered, the requirement of the middle of the cross arm for stability is lowered through the special structural design, material performance can be fully utilized, the structural reliability is improved, steel consumption is reduced, and engineering cost is reduced.
本发明公开了一种输电线路铁塔折弦横担，包括桁架、加强筋一、加强筋二，所述桁架设有两个，所述桁架为网状架构，其外轮廓为由一点集中向两侧呈折线形发散状，两个所述桁架相对设置，两者的集中端相互连接，发散端之间具有间距，两个所述桁架的相对两侧之间分别设有所述加强筋一以及所述加强筋二。本发明的优点是：对于主要承受导、地线张力荷载的钢结构横担，本横担较传统横担可使横担主材内力分布更加均匀、合理，同时还能降低横担构件应力水平，特殊的结构设计，减少了横担中部对稳定性的要求，可充分利用材料性能，提高结构可靠性，减少钢材用量，降低工程造价。
