一种半相贯半螺栓连接的750kV钢管格构式构架
摘要：
本发明公开一种半相贯半螺栓连接的750kV钢管格构式构架，格构式构架柱等宽度的前后两面的腹杆和主杆采用相贯焊接连接、变宽度的左右两面的腹杆和主杆采用节点板螺栓连接，格构式构架梁前后两面的腹杆和主杆采用相贯焊接连接、上下两面的腹杆和主杆采用节点板螺栓接连接；格构式构架整体前后面均采用相贯连接后格构式梁柱主材和腹材截面更小，同时近一半数量的节点板、加劲板及连接螺栓等辅材取消，大幅减少了750kV钢管格构式构架的总体用钢量，经济和节能环保效益显著，整体立面效果更美观轻盈。
摘要（英）：

The invention discloses a half-intersected and half-bolted latticed frame of 750 kV steel pipe, wherein an assistant rod and a main road of equal width of the front and back side are welded across each other, the changeable assistant rod and main rod of the front and back side are connected by bolts of a gusset plate, and the assistant rod and main rod of the front and back side of the girder are welded across each other, and the assistant road and main road of the top and bottom of the girder are connected by bolts of the gusset plat; the section of the main material and auxiliary material of the girder are smaller after intersected connection, and almost half of the gusset plate, stiffening plate and connecting bolts and other auxiliary materials are canceled, thereby the steel consumption of the latticed frame of 750 kV can be decreased, the benefits of the economy and environment protection is more effective, and the overall elevation effect is more beautiful and lightsome.
