Reinforcing device for angle steel power transmission tower main material

Abstract

The invention discloses a reinforcing device for an angle steel power transmission tower main material. The reinforcing device for the angle steel power transmission tower main material comprises a fixed auxiliary material, and the fixed auxiliary material comprises an external auxiliary material and an internal auxiliary material. The external auxiliary material and the internal auxiliary material are both angle steel members, and the internal auxiliary material and the external auxiliary material are arranged in the same direction with the power transmission tower main material. The internalauxiliary material is connected with the inside of the power transmission tower main material. The external auxiliary material is connected with the outside side of the power transmission tower. Theangle steel limb width of the external auxiliary material and the angle steel limb width of the internal auxiliary material are larger than that of the power transmission tower main material. A plurality of bolt holes are vertically and evenly formed in the position, near the edge of the single limb, of the external auxiliary material. Bolt holes are correspondingly formed in the position, near the edge of the single limb, of the internal auxiliary material. The two bolt holes are fixed by bolts. According to the reinforcing device for the angle steel power transmission tower main material, under the condition of meeting the reinforcement and reconstruction of the power transmission tower, the problems that the wind resistance is poor and the power transmission tower is blown down by the wind are solved, the bending stiffness and bearing capacity of the power transmission tower main material are improved, and the safety in use is increased.

Description

technical field [0001] The invention relates to the technical field of improving the structural performance of transmission towers, in particular to a reinforcement device for the main material of an angle steel transmission tower. Background technique [0002] There are still many transmission lines designed in the 1990s, whose structural design and performance can no longer meet today's standards. Many of the existing transmission towers were designed and constructed during the initial development stage of my country's regulations. After the tower collapse accident due to windstorms, the reconstruction of the original drawings is still carried out in order to supply power as soon as possible, and there is often not enough time to redesign the structure of the new transmission tower. , which brings hidden dangers to the wind and disaster prevention of transmission lines. In this context, there is a demand to complete the reinforcement work of existing transmission towers th...

Problems solved by technology

However, frequent tower collapse accidents show that this way of considering safety redundancy cannot guarantee the safety of transmission towers under strong winds

There are still no mature and generally accepted technical measures
