Detachable buckling-restrained reinforcing device for power transmission tower

Abstract

The invention discloses a detachable buckling-restrained reinforcing device for a power transmission tower. The detachable buckling-restrained reinforcing device is mainly composed of three parts, andcomprises reinforcing steel plates, hoops and high-strength bolts, wherein the reinforcing steel plates are arranged on the outer side of an original main material, the axial direction of the reinforcing steel plates is consistent with that of the original main material, a plurality of hoops are sequentially distributed at equal intervals in the axial direction of the reinforcing steel plates, and the hoops can be additionally arranged at the weak positions of rod pieces; and the hoops are fixedly connected with the reinforcing steel plates through the high-strength bolts. For a round pipe component, the four reinforcing steel plates are distributed on the upper portion, the lower portion, the left portion and the right portion of the section of the original main material and fixed together through the four identical hoops by means of the high-strength bolts. For an angle steel rod piece, the two reinforcing steel plates are distributed on the outer side of an angle steel flange and fixed together through the two different hoops on the inner side and the outer side by means of the high-strength bolts.

Description

technical field [0001] The invention relates to a reinforcement technology for an electric transmission tower, in particular to a detachable anti-buckling reinforcement device for an electric transmission tower. Background technique [0002] With the rapid development of social economy, the demand for electric energy in my country's social development has rapidly increased. Electric energy has become a necessity for social development, and transmission lines have become the lifeline project of our country. However, the transmission tower structure itself will also have congenital defects or later damage, which will eventually lead to the destruction of components, and even cause the collapse of the transmission tower structure, seriously affecting people's normal production and life, and even seriously affecting disaster rescue work. Therefore, improving the ability of the power grid to resist natural disasters is of great significance for the reinforcement and protection of...

AI Technical Summary

Problems solved by technology

[0004] So far, there are still some problems in the strengthening method of transmission towers. First, the problem of construction difficulties. Some reinforcement methods need to drill holes in the raw materials of transmission towers, and some transmission towers to be reinforced are located in remote locations, which leads to construction electricity consumption. There is a lot of difficulty in obtaining it, so the construction is more difficult and the implementation is more difficult

The second is the issue of safety. Some reinforcement methods require temporary disassembly of the original stress-bearing components, which will redistribute the internal force of the tower material and put the tower in a dangerous state, which should be avoided as much as possible.
