Abstract
The utility model relates to a novel combined steel pipe pole, which belongs to the field of a transmission and transformation line project. The novel combined steel pipe pole comprises main pipes, a cross bar and a cross arm. The main pipe is vertical and free from gradient. The main pipes are connected with a flange through the cross bar. The cross arm is connected with the main pipes through a joint plate and a bolt. The cross bar is structural steel with a I-shaped section and is connected with the main pipes through the joint plate and the bolt. Compared with an angle iron tower, the foot distance of the novel combined steel pipe pole is small, the width of a line corridor is decreased, so that removal and vegetation deterioration are reduced for the benefits of saving resources and protecting environment. And the novel combined steel pipe pole is attractive in appearance, and meets the demand of appearance of urban electric transmission lines. The novel combined steel pipe pole provided by the utility model is suitable for 500Kv, 220kV and 110kV multiloop transmission line projects, and can be used as a tangent tower, a span tower, a corner tower, a terminal tower and a branch tower.
Description
Technical field
The utility model relates to a kind of novel combined steel pipe bar, belong to the power transmission and transformation line engineering field.
Background technology
Transmission tower is the huge and very important tall and slender structure of a kind of engineering quantity.As the electric power facility of important lifeline engineering, often can use the transmission tower of all kinds and different purposes in the work transmission line.
Along with improving constantly of transmission line of electricity transmission line capability and electric pressure, the application in the developed area of common-tower double-return and multi-loop line has become inevitable trend, and the developed area is more and more harsher to the requirement in circuit corridor, the place is more and more less, the circuit corridor is more and more narrower and small, stressed the differing of single pole steel pipe pole satisfies the demand of tower structure design surely, but conventional steel tower root is opened and land occupation is larger, can not satisfy the demand of urban construction.Therefore, develop that the tower structure blast is little, rigidity is large, the tower that can give full play to material property is more and more urgent.For the king-sized multiloop angle tower of load, adopt the single pole steel pipe pole, because the rod member root bending moment is large, cause predominant tube diameter larger, stock utilization is low, even the problem such as processing difficulties appears, so the Novel rod tower structure form that exploitation is applicable to the urban area multiple loop transmission line is very necessary.
The utility model content
For the deficiency that exists on the prior art; the utility model provides a kind of combined steel pipe bar of new structure; comparing its root with angle steel tower opens little; reduced the circuit width of corridor; thereby reduced removal and vegetation deterioration, be conducive to the appearance requirement that the city transmission line of electricity has been satisfied in resources conservation and environmental protection.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of novel combined steel pipe bar comprises supervisor, tabula and cross-arm, and described supervisor is connected with flange by tabula between the described supervisor vertically without the gradient; Described cross-arm is connected with supervisor by gusset plate, bolt; Described tabula is I-shaped cross-section shaped steel, is connected with supervisor by gusset plate, bolt.
Above-mentioned flange is rigid flange or band neck forged flange.
Above-mentioned I-shaped cross-section shaped steel is wide width wing I-shaped cross-section shaped steel.
The Steel material of above-mentioned supervisor and cross-arm is selected Q345, Q420 or Q460.
The utility model compared with prior art useful effect is:
1, this pyramidal structure is succinct, profile is graceful, permeability is good, root is opened littlely, has significantly reduced tower position floor space, is applicable to the city work transmission line.
2, compare with traditional single pole steel pipe pole: the integral rigidity of combined steel pipe bar is larger, can effectively reduce the cat head displacement, also can reduce the engineering quantity on steel tower and basis, reaches the purpose of saving resource.
3, use first the Q460 high-strength steel to compare with Q345 in the 220kV Designing Steel Tube Pole, tower weight reduces more than 20%
4, adopt the i iron cross section at the combined steel pipe bar in the face crossbeam first, the node power transmission is clear, and structure is succinct, processing, easy construction.
