Technology for anti-buckling and reinforcing metal structure by adopting fiber-reinforced composite

Abstract

A method for anti-buckling and reinforcing by a fiber-reinforced composite belongs to the technical field of metal component anti buckling and reinforcing and is characterized in that the method comprises the following three different and independent reinforcing methods of: filling solid light materials, fiber-reinforced composite profiles and wrapping fiber cloth for reinforcement; filling the solid light material; subsequently wrapping the fiber cloth for reinforcement; fully sheathing the fiber-reinforced composite sleeve on the reinforced component and filling the solid light material subsequently; and reinforcing the component by wrapping the fiber cloth. The reinforcing method is flexible, convenient, fast and safe, has small effects on the structure, has light additional weight, obviously improves the bearing capability, and can be combined with other reinforcing types.

Description

field of invention [0001] The invention relates to a buckling-resistant and reinforced metal structure method with quick construction, simple process, light material and remarkable effect, and belongs to the field of civil engineering. Background technique [0002] Buckling failure is a major form of structural member failure, and it is the most common in steel structures. Buckling damage usually occurs suddenly and can cause serious damage. In the engineering history of various countries in the world, accidents caused by the instability and damage of compression bars are common, such as: the collapse of the Quebec Bridge in Canada in 1907, the collapse of the grid structure of the Hartford Stadium in the United States in 1978, and the ice and snow disaster in southern my country in early 2008 Massive collapse of transmission steel towers. In recent years, my country's steel structure has developed rapidly. Due to lack of experience or excessive pursuit of economy, many str...

AI Technical Summary

Problems solved by technology

After the ice and snow disaster in the south last year, a large number of transmission steel towers in China urgently need to be reinforced. However, most of the steel towers are in the wild, with inconvenient transportation and lack of suitable reinforcement methods. Therefore, there is an urgent need for reinforcement technologies that are simple in construction, light in use, and effective.

[0003] At present, the main methods of strengthening steel structures in actual engineering include component replacement, load reduction, structural system change, increase of component cross-section and connection strength, prestressed cables, etc. These methods have their applicable conditions and scope, and some are very Difficult to meet the requirements of construction and use, such as no disassembly, no open flames, etc.; some will bring new problems to the structure, such as local damage, residual stress, etc.
