Description

The cross connection node of transmission of electricity steel tube tower and steel tube component thereof
Technical field
The utility model relates to the transmission of electricity steel tube tower, more specifically, relates to the cross connection node of transmission of electricity steel tube tower steel tube component.
Background technology
Electric power line pole tower at body of the tower web member and place, the upper and lower plane of the cross-arm intersection materials that adopt more.For the angle steel crossing members, can realize through the direction of adjustment limb directly connecting.
In high pressure especially UHV transmission technology, usually adopt steel tube tower as power transmission tower.The member of steel tube tower mainly adopts steel tubing, and for example its main material adopts tubing (steel tubing), and its oblique material also adopts tubing (steel tubing) usually, and its tabula material, auxiliary material etc. can adopt and also can not adopt tubing (steel tubing).Said steel tubing is formed by steel or alloy steel, therefore in the field of businessly common such power transmission tower is called steel tube tower.
And for the steel pipe crossing members, wherein one of material of must will intersecting cut-offs in interconnection place, realizes interconnection through passing through welding or junction plate mutually then.
In steel tube tower, possibly there is the connected node of some intersection tubing.For example, the oblique material connected node that intersects is one of allusion quotation shape node on the transmission of electricity steel tube tower, on steel tube tower, uses general.With respect to the angle steel tower structure, it is much complicated that the connected node of the intersection tubing of steel tube tower structure (for example intersect oblique material etc.) is wanted, and this also is one of factor of on iron tower, using of restriction steel tubular structure.Therefore inquire into steel tube tower intersection tubing node type of attachment is had great importance to applying of steel tubular structure.
For example, at present the most of steel tubular structure of China intersects the connection of oblique material and all adopts welded flange, and the node rigidity of this form is big, generally be not weaker than the rigidity of pipe fitting, but the difficulty of processing of this node and workload is bigger, are unfavorable for applying of steel tubular structure.
