Ultra-high-tension power transmission line is important national vital engineering, once the accident that collapses, it will lead to large-scale electricity Power supply discontinuity, influences daily life, brings extreme loss to national economy and the security of the lives and property.

Power transmission tower plays a part of supporting high voltage transmission line, and in existing ultra-high-tension power transmission line, most power transmission towers are It is built by angle with equal legs.Transmission tower is the very big high-rise structure of depth-width ratio, very sensitive to wind-force, usually by Collapse in wind-force effect.It is influenced by typhoon and monsoon, wind-force suffered by the power transmission tower of coastal area is larger, the regions such as power transmission tower column foot Stress is larger, and the intensity and local stability requirement for regions such as column foots are higher.Furthermore in the high-tension line being on active service now, Many old-fashioned Transmission towers designs are unreasonable, and the power transmission tower wind resistance ultimate bearing capacity for many years of being on active service under Drop.

In order to guarantee transmission line of electricity normal operation and transmission of electricity safety, the wind loading rating of transmission line of electricity is improved, it is necessary to edge Sea etc. is affected by the wind the power transmission tower frame in biggish region and larger, the more fragile region of the old power transmission tower stress of active service is mended Force admittedly, avoids line interruption bring power supply pressure and economic loss.

Current reinforcement and strengthening mode is mainly fixture, bolt or welding manner.Conventional brace connection can not accomplish with Former angle steel main material is closely connected；It is bolted and needs the aperture on power transmission tower angle steel, main material remitted its fury can be led to because of aperture, and sometimes High altitude operation is needed, punching difficulty is big, there is the phenomenon that punching is inaccurate, reaming is larger, greatly reduces consolidation effect；Welding side The high temperature action that formula diagonal steel main material component generates increases the brittleness of main material, causes angle steel main material easy to crack.

(3) summary of the invention

The present invention will overcome the disadvantages mentioned above of the prior art, provide it is a kind of it is closely connected with former angle steel main material, without punching and weldering It connects, the power transmission tower angle steel reinforcing device that consolidation effect is good.

Power transmission tower angle steel reinforcing device of the invention is mended including having with the first of power transmission tower main material identical cross-section Strong angle steel, the second reinforcement angle steel, third reinforcement angle steel, power transmission tower main material and the first reinforcement angle steel, the second reinforcement angle steel, third are mended Strong angle splice joint is at cross-shaped configuration；
