Active force application system for fiber fabric

Abstract

The invention discloses a fiber fabric active force-applying system. The fiber fabric active force-applying system comprises fiber fabric, a first clamp, a second clamp, a force applying piece and a fixing piece, and the two ends of the fiber fabric are correspondingly fixed to the first clamp and the second clamp; the force applying piece can apply force to the first clamp, so that the fiber fabric is stretched; and the fixing piece is used for fixing the position of the stretched fiber fabric. The fiber fabric active force-applying system is used for reinforcing a concrete beam and applyingprestress to the fiber fabric so that the fiber fabric can give full play to the effective bearing capacity, strength utilization of the fiber fabric is kept to a high level, and the fiber fabric active force-applying system has the good effect on improving the load-bearing capacity and deformation of reinforced components.

Description

technical field [0001] The invention belongs to the field of engineering structure reinforcement application science, and relates to a fiber fabric active force application system. Background technique [0002] my country is a rapidly developing country with a large population, a wide area and a large climate span. Due to the influence of natural disasters (earthquakes, fires, floods and landslides, etc.), service life restrictions, functional changes, construction quality and other factors, there are a large number of buildings in my country. Repair and reinforcement are required, so the problem of repairing structures has always been a constant topic in the engineering community. Although the traditional reinforcement and repair technology can play a role in reinforcement, it has obvious shortcomings - low construction efficiency, long construction period, and the addition of a support system reinforcement method has a greater impact on the appearance of the structure and t...

Although the traditional reinforcement and repair technology can play a role in reinforcement, it has obvious disadvantages - low construction efficiency, long construction period, and the reinforcement method of adding support systems has a great impact on the appearance of the structure and the usable space

Fiber materials have been discovered and utilized very early for their light, high strength, corrosion resistance, and convenient operation. Because fiber composite materials have high tensile strength, the strength of fiber materials is only effective carrying capacity when no prestress is applied. less than 20%, seriously wasting its superior performance of high strength
