Structure-frp material bond construction and bonding method

Abstract

Provided are: a structure-FRP material bond construction, which is a structure for bonding FRP material to structures and is characterized by a bonding layer formed from a resin and a fiber substratebeing interposed between the structure and the FRP material and the bonding layer protruding from the edge of the FRP material; and a bonding method. Repair or reinforcement of an existing structure can be made easily and reliably at a construction site with the required FRP material, and in particular, a sufficiently strong bonding force between the structure and the FRP material for repair or reinforcement can be manifested and an intended repair or reinforcement performance of the FRP material for the structure can be exhibited more reliably.

Description

technical field [0001] The present invention relates to a bonding structure and a bonding method of FRP (fiber reinforced plastic) materials and structures, and particularly relates to an existing structure that needs to be changed in use or an existing structure that has a cross-sectional defect due to corrosion or the like FRP materials and FRP materials that can reliably improve or restore the desired performance of existing structures without bolting or welding, and can easily and reliably use the required FRP materials for repair and reinforcement even at the construction site. The bonding structure and bonding method of the structure. Background technique [0002] In the case of improving the performance of an existing structure (for example, a structure whose surface material is steel or FRP) in order to improve its performance, as additional structural parts such as steel plates and base materials (existing structures) The joints are bolted or welded. However, in t...

AI Technical Summary

Problems solved by technology

Since the reinforcing fiber base is a resin-impregnated prepreg sheet, the adhesive strength can be ensured, but the process time and effort are increased, and depending on the resin, the curing of the resin begins to occur between sealing and vacuum suction. , in addition, air may remain on the bonding surface, resulting in low bond strength

In addition, although the extension parts are of high quality because they are made of prepreg sheets, there is a problem of complicated operation steps due to the need for heat source equipment, etc., due to the construction involving heating.
