[0002] The tower is mainly composed of steel structures, which are fixed by welding and bolting. The rods are mainly composed of single equilateral angle steel or combined angle steel. The steel tube tower structure has relative technical and economic advantages. The steel structure tower bears small wind pressure, has large cross-sectional bending stiffness, simple structure, clear force transmission, and can give full play to the bearing performance of the material. On the one hand, it can reduce the weight of the tower and reduce the foundation force. On the other hand, it is conducive to enhancing the ability to resist natural disasters under extreme conditions. The cross-section of the steel tube component is centrally symmetrical, the material is evenly distributed around, and the cross-sectional bending stiffness is large. In terms of structural connection, the main material of the steel structure tower is connected by flange or welded by welding equipment. The main material of the tower is connected by internal and external packaging, and other rods are mainly connected by connecting plates and bolts.
