Abnormal shape prevents weighing down tower pole angle steel

The utility model provides a be connected with one on the angular bisector and prevent weighing down the extension section that abnormal shape prevents weighing down tower pole angle steel, characterized by adopts heterotypic right angle angle steel as high tension transmission line shaft tower owner material, and this abnormal shape right angle angle steel is at two right -angle sides of right angle angle cross section to it is equipped with a dog to weigh down extension section tail end preventing. The beneficial effects of the utility model are that, through changing angle steel owner material cross sectional shape, what compensate former angle steel owner material shortcoming prevents weighing down the function, improves the critical power of angle steel unstability simultaneously. The utility model relates to an under the circumstances about equalling with former shaft tower angle steel cross sectional area, the cross sectional shape of change angle steel follows template structure to say, has improved the mechanical properties of angle steel steel, and has not increased the weight of whole shaft tower. The efficiency of operation personal security nature and work is improved, operation people intensity of labour, equipment fortune dimension cost is reduced with safety in production life injures and deaths accident probability, practice thrift social resources, the environment is protected. Compensate ordinary angle steel and prevent weighing down the function disappearance, demonstrate fully the safety in production theory of " human oriented ".
