Problems solved by technology

[0006] In view of this, in order to solve the problem that the CFRP sheet can only be kept horizontally close to the surface of the reinforced member and cannot be bent when the existing corrugated tooth anchorage is clamping the CFRP sheet, an adjustable angle anchor is proposed. CFRP Sheet Clamping Anchor

Embodiment Construction

[0037] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0038] Such as Figure 1 to Figure 7 As shown, a CFRP sheet clamping anchor with adjustable angle mainly includes two clamping groups, and the two clamping groups are hinged to each other, and it is characterized in that: the clamping groups include two splints and Two hinges 2, the two splints are arranged facing each other, the clamping surfaces of the two splints are opposite, the splints correspond to the hinges 2 one by one, and the splints and the corresponding hinges 2 are hinged to each other , all the hinges 2 are hinged to each other;

[0039] The splint includes a splint body 1 and a clamping block 3, an installation groove is provided on the clamping surface of the splint body 1, and the clamping block 3 is embedded in the installation groove, and the clamping block 3 is embedded in the installation groove. The bottom of the groove is provided w...

Abstract

The invention discloses an angle-adjustable CFRP sheet clamping anchorage, comprising two clamping groups, the two clamping groups are hinged to each other, the clamping group includes two splints and two hinges, the two splints are For setting, the clamping surfaces of the two splints are opposite, the splints correspond to the hinges one by one, the splints and the corresponding hinges are hinged to each other, and all the hinges are hinged to each other. Using the angle-adjustable CFRP sheet clamping anchor of the present invention, during the clamping process of CFRP sheet, the CFRP sheet can be directly squeezed by the top-tightening hole, avoiding the CFRP sheet between the two splints The stress is too concentrated, so that the stress on the CFRP sheet is dispersed, ensuring that the CFRP sheet is evenly stressed, improving the clamping stability and avoiding shear damage to the CFRP sheet; the hinge can be used to realize the connection between CFRP and the reinforced member. The angle between them can be adjusted arbitrarily; the structure is simple and the clamping is stable.

Description

technical field [0001] The invention relates to an angle-adjustable CFRP sheet clamping anchor, in particular to an angle-adjustable CFRP sheet clamping anchor. Background technique [0002] Concrete beams in modern buildings, traffic, bridges and other engineering structures often suffer from insufficient bearing capacity or cracking due to environmental erosion, material aging, structural function changes, or natural disasters and human disasters. , there is a huge security risk. [0003] Reinforcement and repair of engineering structures is the most important preventive method now. Carbon fiber reinforced composite materials (referred to as CFRP) have light weight, high strength, corrosion resistance, fatigue fracture resistance, not easy to creep, low coefficient of linear expansion and relaxation rate, etc. It is widely used in the reinforcement and repair of engineering structures. According to the shape of the material, CFRP rods and CFRP sheets are commonly used; f...
