Description

The reinforcement means of electric power pylon
Technical field
The invention belongs to the electric power pylon field, especially a kind of reinforcement means of electric power pylon.
Background technology
Electric power pylon is the visual plant in the electric power transfer engineering.In order to guarantee the operate as normal of electric power transfer, electric power pylon should fix on the ground with being stabilized, and has requirements such as certain wind resistance, anti-ice cover.But the electric power pylon that uses much comes fabrication and installation according to old version standard now, and its performance indications can not adapt to more and more rugged environment needs.For example, the strong sleet freezing weather of China's southern area just causes a lot of electric power pylons because the icing accidents such as causing electric grid large area power cut of collapsing at the beginning of 2008.In order to improve the steadiness of electric power pylon, can adopt two kinds of methods to realize usually: a kind of method is to use more firm electric power pylon to replace existing electric power pylon, and there are problems such as expense height, construction is complicated, the replacement cycle is long in this method; Another kind method is that existing electric power pylon is reinforced, promptly on the main material of electric power pylon, make installing hole and use bolt will reinforce sheet material and be installed on the main material, the problem that this method exists is: make the installing hole constructional difficulties on main material, owing to make the structure that installing hole has destroyed main material on main material, its reinforcement performance is difficult to guarantee simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of reinforcement means of with low cost, method is simple and reinforcement performance is high electric power pylon is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of reinforcement means of electric power pylon may further comprise the steps:
(1). two facades in each gusset plate outside that installs mutually by node bolt with main material use this node bolt back-to-back to install two connecting angles respectively;
(2). between above-mentioned two connecting angles, adopt fastening bolt to fix a reinforcing angle parallel respectively with main material;
(3). the intersection point place of the horizontal material between two adjacent gusset plates or oblique material and main material utilizes former intersection point bolt to install a transverse slat, and the other end of this transverse slat installs by fastening bolt and reinforcing angle;
(4). the bottom of reinforcing angle is packed on the tower angle, promptly finishes reinforcing electric power pylon.
And the bottom of described reinforcing angle is packed on the tower angle by welding manner.
And described reinforcing angle is identical with the material of main material.
And described electric power pylon is the 110ZGu2 electric power pylon.
Advantage of the present invention and good effect are:
1. this reinforcement means makes full use of the installing hole on the existing main material, at a pair of connecting angle of each gusset plate back-to-back installation in the outside, transverse slat is installed at the intersection point place of the horizontal material between two adjacent gusset plates or oblique material and main material, using fastening bolt that reinforcing angle is parallel to main material is installed on the connecting angle, be about to main material, connecting angle, transverse slat and reinforcing angle are installed together, thereby realize reinforcing function to electric power pylon, this reinforcement means has made full use of the installing hole on the main material, do not need to punch again and reinforcing angle and main material can be solidly installed, guaranteed the reinforcement performance of electric power pylon at main material.
2. this reinforcement means only need use original installing hole installation reinforcing angle on the main material, and it is with low cost, construction is simple, the duration is short, has solved problems such as the expense height that the integral replacing electric power pylon brings, construction is complicated, the replacement cycle is long.
3. the present invention has improved the reinforcement performance of electric power pylon effectively, has advantages such as with low cost, that construction is simple, the duration is short, can be widely used on the existing electric power pylon.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further described:
A kind of reinforcement means of electric power pylon is that existing electric power pylon is reinforced.Be that the example explanation is illustrated with the 110ZGu2 electric power pylon below.
Existing electric power pylon is made of pedestal 8, tower angle 7, body of the tower, cat head 1 and cross-arm 2, body of the tower is the tower frame structure that four main materials 6 and the horizontal material 3 therebetween that interlocks, oblique material 4 are constituted, the a plurality of nodes place that is constituted at main material, horizontal material and oblique material joint all is equipped with gusset plate 9, adopt bolt to be installed together above-mentioned three by this gusset plate, every main material constitutes by the multistage angle steel and is packed in the gusset plate inboard.Main material and horizontal material, main material install by the intersection point bolt with the intersection point of oblique material.The bottom of body of the tower is packed on the pedestal in four tower angles, and the top of body of the tower is cat head, and level is installed several cross-arms between cat head and body of the tower.This reinforcement means mainly is to use original installing hole on the main material reinforcing angle 5 to be installed in abreast the outside of main material, that is: use node bolt that a pair of connecting angle 10,12 back-to-back is installed in each gusset plate outside, re-using fastening bolt 11,13 is installed in reinforcing angle between two connecting angles, the intersection point place of the horizontal material between two adjacent gusset plates or oblique material and main material uses on the former intersection point bolt transverse slat 15 is installed, and is installed together by the middle part of fastening bolt 14,16 with this transverse slat plate and reinforcing angle again.
