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-bearing embracing type steel angle reinforcing and correcting device for a power transmission tower. The device comprises reinforcing steel angles, hoops and connectors. The reinforcing steel angles are placed on the inner sides of two limbs of a to-be-reinforced steel angle; the axis direction of the reinforcing steel angles is parallel to the to-be-reinforced steel angle; the outer walls of the two limbs of the reinforcing steel angles are attached to the inner wall of the to-be-reinforced steel angle; the hoops are placed on the outer sides of the reinforcing steel angles and the to-be-reinforced steel angle and connected through high-strength bolts; three sets of threaded holes are formed in the side wall of each hoop; the axis of the first set of threaded holes is perpendicular to the axis of the second set of threaded holes; the first set of bolts penetrate through the first set of threaded holes to apply reinforcing force to the outer side of one limb of the to-be-reinforced steel angle; the second set of bolts penetrate through the second set of threaded holes to apply reinforcing force to the outer side of the other limb of the to-be-reinforced steel angle; and the third set of bolts penetrate through the third group of threaded holes to apply reinforcing force to the reinforcing steel angles through the connectors.

Description

technical field [0001] The invention relates to a structure strengthening technology of a power transmission tower, in particular to a bolt pressure-embracing angle steel reinforcement and correction device for a power transmission tower. Background technique [0002] At present, the transmission tower structure itself has insufficient bearing capacity or later 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 seriously affects disaster rescue work. For the angle steel members of transmission towers that have buckled and damaged, although the angle steel members can continue to be used in the case of slight damage, they can only be replaced if they have been deformed, resulting in a large waste of material resources. Therefore, to improve the ability of the power grid to resist natural disasters, the transmission towers should be put i...
