Abstract

The utility model discloses combined angle steel, which comprises a first steel plate, a second steel plate and a third steel plate, wherein the first steel plate and the second steel plate are mutually vertical and are connected in an end-to-end way, one end of the third steel plate is connected with the common end of the first steel plate and the second steel plate, and the integral cross section of the first steel plate, the second steel plate and the third steel plate is in a Y shape. The combined angle steel effectively overcomes the defects that deformation of the traditional combined angle steel is incongruous, and the stress of each section of angle steel is not uniform. In addition, the dimension of the third steel plate is flexible and variable, and the regulation is convenient, so the adverse influence of torsional buckling caused when the symmetrical section axes is pressed can be effectively weakened. In addition, the steel consumption and the work load can also be saved, so the cost for building electric transmission line iron towers is reduced. Simultaneously, the utility model also discloses an electric transmission line iron tower with the combined angle steel.
