Problems solved by technology

However, most of the current reinforcement methods need to drill holes in the original rods of the transmission tower, resulting in weakening of the original rods, affecting the force transmission path and bearing capacity of the transmission tower; or temporarily dismantling the original stress-bearing components, which will The internal force of the tower material is redistributed, and the force of the rods in the transmission tower is more complicated, resulting in unclear determination of the bearing capacity of the transmission tower

Abstract

The invention discloses a bolt pressure-embracing angle steel reinforcement and correction device for a power transmission tower, which includes a reinforcement angle steel, a hoop and a connector; The angle steel to be reinforced is parallel, and the outer walls of the two limbs of the reinforced angle steel are attached to the inner wall of the angle steel to be reinforced; the hoop is placed on the outside of the angle steel to be reinforced and the angle steel to be reinforced, and connected by high-strength bolts; the side wall of the hoop is provided with three A group of threaded holes, the axes of the first and second groups of threaded holes are perpendicular to each other, the first group of bolts pass through the first group of threaded holes to apply reinforcement force to the outside of one of the angle steel to be reinforced, and the second group of bolts pass through the second group of threads The holes apply reinforcement force to the outside of the other limb of the angle steel to be reinforced; the third group of bolts pass through the third group of threaded holes to apply reinforcement force to the reinforcement angle steel through the connector.

Description

technical field [0001] The invention relates to a structural reinforcement technology of a power transmission tower, in particular to an angle steel reinforcement and correction device of a bolt-bearing pressure-embracing power transmission tower. Background technique [0002] At present, the transmission tower structure itself has insufficient bearing capacity or late damage, which eventually leads to the destruction of components, and even the collapse of the transmission tower structure, which seriously affects people's normal production and life, and even affects disaster rescue work. For the angle steel members of the transmission tower that have suffered buckling damage, although the angle steel members can continue to be used in the case of minor damage, they can only be replaced after deformation, resulting in a lot of waste of material resources. Therefore, the ability of the power grid to resist natural disasters is improved, and the transmission tower is used for s...
