Study On Construction Method Of Concrete Members Strengthened With FRP Sheets

Development of construction industry has three stages, many new buildings to building and repairing and now to repairing and reforming of existing buildings and old building repairing ang strengthened.now,some old buildings want to continue safety using, some special materials must be used in the old buildings with special construction methods.FRP is a kind of bunchiness composite material, with high strength and high elastic modulus.this material's character is high tensile strength,resist corrosion resistance, low density, thermal expansion coefficient is similar with concrete. When the temperature outer change, FRP and concrete can works together ,haven't more lager temperature stress, technology of stengthened conerete Constructer with FRP be used widely .This paper analysis strengthened concrete constructer with FRP, and strengthened concrete constructer with FRP have some advantages: Lightweight and High Strength, anticorrosive properties, improve the durability compared, so early detecting structural damages. prolong the service life of structure. convenient construction, the best work efficiency, short construction period, lower noise, less effect on the ambience. Study on two kinds of methods, embedded and Externally Bonded.Through let to Daqing city Hu way district village rainbow multi-layer brick of home mix structural one - storeyed balcony baseplate of residential building hang, choose roof beam go on, strengthen, punish with fair wind this text, main construction method to adopt, stick to FRP go on, strengthen outside, hang, choose roof beam tip to paste annular to close carbon fiber slices of material go on, strengthen, punish to it in concrete, strengthen the scheme to provide by the specialized department, concrete construction is constructed by the specialized operation team .According to the analysis of the results, by some engineering example. With FRP strengthened concrete i can realize . At certain extent prolong the service life of concrete structure. then reduce project cost, better social economic benefit, make due contribution for society.
