The cross diagonal material of a common power transmission iron tower usually adopts angle steel or steel pipes, and the rod piece has higher strength and rigidity and can bear higher tensile force and pressure. However, the cross-sectional area of the angle steel or steel pipe member is large, a large amount of materials such as gusset plates and bolts are needed when the angle steel or steel pipe member is connected with the main material of the tower body, the defects that the tower material occupies a large area and is not easy to disassemble and the like exist, and meanwhile, the rod piece is easy to damage in the disassembling process and cannot be used continuously, so that waste is caused. Therefore, the temporary iron tower also considers that round steel replaces angle steel or steel pipes to be used as cross inclined materials of the tower body, the round steel is a pull rod and only bears the pulling force, the size is small, the structure is simple, the repeated use is easy, and the pull rod is connected with the tower body through a turnbuckle bolt.
