Furthermore, the main chord member is formed by welding two angle steel buckles with the same specification into a square tube, one end of the square tube is provided with a plug welding hole, and the plug welding hole is welded and fixed with a steel column joint.
Further, two pin shaft holes are formed in the steel column connector.
Further, the axes of the two pin shaft holes on the steel column connector are parallel to each other.
Further, the side wall of the steel column joint groove is provided with a pin shaft hole corresponding to the pin shaft hole on the steel column joint.
Further, a reinforcing plate is fixed at the position of the pin shaft hole on the side wall of the steel column joint groove.
Further, the pin shaft hole axes of the adjacent main chord upper steel column connectors of the double pin shaft connection standard section are mutually perpendicular.
The beneficial effects of the utility model are as follows:
1) The bearing capacity of the connector is high, the service life of the main chord member is prolonged, and the deformation of the tower body is prevented;
2) The standard section is convenient to assemble and disassemble through pin shaft connection;
3) The upper and lower adjacent main chords are connected in a plug-in mode, so that the assembly and disassembly are more convenient, and the connection strength of the adjacent main chords is improved;
4) The pin shaft holes on the same main chord member are in the same direction, so that the tooling is simple and convenient to design, easier to weld and more convenient to install and detach.
