Problems solved by technology
[0002] At present, most of the commonly used steel tower compression reinforcement measures use bolt holes, welding, gluing and other connection methods to add auxiliary main materials on the basis of the original tower materials to increase the transmission tower components and overall compressive stability, but bolt holes And welding will affect or even reduce the material performance of the original tower material, and it is difficult to evaluate the impact of reinforcement measures on the overall safety; there are durability problems in the complex environment of the transmission tower in the field of gluing connection, which affects the actual application effect of the corresponding tower reinforcement device

Abstract
The present invention proposes a single-piece circular-arc plate-based steel pipe transmission tower component compression reinforcement device and its manufacturing method, which is characterized in that it includes: a single-piece circular-arc plate and a plurality of clamps; the single-piece circular-arc plate is closely attached to It is installed on the outer surface of the steel pipe tower member to be reinforced, and is tightly connected with the steel pipe tower member through a plurality of equidistantly arranged clamps; the clamp is composed of U-shaped bolts and a support base. Under the premise of not destroying the main material section and material properties of the original iron tower, it can reinforce the compressive capacity of the key components of the steel pipe iron tower and improve the safety of the iron tower. The calculation principle of the invention is clear, the preparation method is simple, and the invention has wide application value in the field of disaster prevention and mitigation of power transmission lines.
Description
technical field [0001] The invention belongs to the technical field of disaster prevention and mitigation for power transmission lines, and in particular relates to a compression-resistance reinforcing device for a transmission tower component based on a single circular-arc plate steel pipe and a manufacturing method thereof. Background technique [0002] At present, most of the commonly used steel tower compression reinforcement measures use bolt holes, welding, gluing and other connection methods to add auxiliary main materials on the basis of the original tower materials, so as to increase the transmission tower components and overall compressive stability, but bolt holes And welding will affect or even reduce the material properties of the original tower materials, and it is difficult to evaluate the impact of reinforcement measures on the overall safety; there are durability problems in the field complex environment of transmission towers with glued connections, which af...
