Description
技术领域technical field
本实用新型涉及一种输电线路钢管杆。The utility model relates to a steel pipe pole of a power transmission line.
背景技术Background technique
输电钢管杆横担常用的连接方式有连板加劲和法兰连接两种。连板加劲采用两块钢板配4~8块加劲板焊接至主杆,法兰连接采用配对法兰和一周若干加劲板焊接至主管,两者均需较多数量加劲板,给设计、放样、下料、组装、焊接等一系列工序带来较大的工作量,效率较低。而且因荷载作用时横担根部的受压部位容易产生应力集中,使局部受压易导致主杆局部压曲,所以横担又不宜直接与主杆连接。There are two commonly used connection methods for transmission steel pipe pole cross arms: connecting plate stiffening and flange connection. Two steel plates and 4 to 8 stiffening plates are used to weld the connecting plate to the main rod. The flange connection adopts matching flanges and several stiffening plates welded to the main pipe. Both require a large number of stiffening plates for design, lofting, A series of processes such as blanking, assembly, and welding bring a large workload and low efficiency. Moreover, stress concentration is likely to occur at the compressed part of the root of the cross-arm when the load acts, and local compression can easily lead to local buckling of the main rod, so the cross-arm should not be directly connected to the main rod.
