Abstract

The present invention relates to a stretching anchorage device capable of utilizing fiber to strengthen building structure and fiber strengthening method. In particular, it discloses an anchorage design capable of using prestressed aramid fiber to strengthen building structure and its correspondent stretching process. Said anchorage device is composed of fixing component, stretching component, fixed seat and stretching bar. Its stretching mode is a reverse stretching mode, and its stretching bar is movable drawable one.

Description

technical field [0001] The invention belongs to the technical field of civil building structure reinforcement, and relates to a tension anchor for building structure fiber reinforcement and a fiber reinforcement method. Background technique [0002] Aramid fiber (Aramid) is a fully aromatic polyamide fiber with high strength, high elasticity, good heat resistance and corrosion resistance, and can be used in various building structure reinforcement fields. [0003] Aramid fiber cloth has the following advantages: [0004] (1) It has a wide range of applications, and can be used for the reinforcement of bridge pier bodies, pier columns, solid slabs, hollow slabs (beams), railings and other concrete structures; [0005] (2) The construction is simple and fast, the fiber sheet is directly pasted and wrapped on the surface of the building, the process is simple, and three or two people can construct it without templates and large hoisting equipment; [0006] (3) High strength, ...
