Abstract
The invention relates to a combined steel angle tower for electric transmission lines. The combined steel angle tower for the electric transmission lines comprises a tower body and pins. The cross section of the tower body is of a quadrangle structure, the tower body is composed of a tower head, a main tower body and tower legs, the tower head, the main tower body and the tower legs are formed through the method that main materials and inclined materials are connected through bolts, wherein the main materials of the main tower body and the tower legs are respectively cross combined main materials formed by two steel angles which are of the same standard and are connected through connecting boards and bolts, the main material of the tower head is composed of single-steel-angles, one combined main material of the main tower body and the tower legs is provided with the pins, and each connecting board is a cross connecting board and is formed through the method that two short boards are symmetrically welded to the two sides of a long board. Compared with the prior art, the combined steel angle tower for the electric transmission lines has the advantages of being simple in structure, scientific and practical. The main materials are combined steel angles, so that the mass of the steel angle tower is greatly increased, the rigidity of the steel angle tower is effectively improved, the windproof effect of the steel angle tower is enhanced, occurrence of potential safety hazards is avoided, and the natural-disaster-resistant performance is improved.
Description
Technical field
The present invention relates to electric industry technical field, particularly a kind of transmission line of electricity combination angle head tower.
Background technology
Along with the development of China's electric utility is advanced by leaps and bounds, angle steel tower of power transmission line is widely used, but present used angle steel tower has certain irresistible defect, a lot of angle steel towers have that main quality is light, poor rigidity, protection effect are poor, have the problems such as potential safety hazard, generation when natural calamity, cause caving in and toppling over of angle steel tower, to client, bring very large trouble, can not guarantee normal power supply completely.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, good rigidly, transmission line of electricity combination angle head tower that protection effect is good.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of transmission line of electricity combination angle head tower, comprise steel tower body and pin nail, the cross section of described steel tower body is quadrilateral structure, steel tower body consists of tower head, tower body and tower leg, tower head, tower body and tower leg are bolted and are formed by main material and oblique material, wherein the main material of tower body and tower leg combines main material by two angle steel with equal-specification by junction plate and bolt shape across, and the main material of tower head consists of single angle, and one of them combines tower body and tower leg main material and be provided with pin nail.
Described junction plate is cross junction plate, is symmetrically welded at block length slope both sides forms by two short slabs.
The spacing of described pin nail is 450-550mm, the pin pitch of nails tower leg lower end 1200mm on tower leg under.
Described main material is Q345L type angle steel or Q420L type angle steel.
Described oblique material is L-type angle steel.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of transmission line of electricity combination angle head tower, there is feature simple in structure, science is practical, because main material is combination angle steel, greatly increased the quality of angle steel tower own, effectively raise the rigidity of angle steel tower, strengthen the protection effect of angle steel tower, avoided the generation of some potential safety hazards, improved opposing natural calamity performance.
