Qianjiang reinforcement company used carbon fiber reinforced reinforcement methods. Carbon fiber reinforcement: carbon fiber which is a fibrous carbon material. It is in the thousands of degrees of heat through manufactured by a special process of high-tech materials products. Carbon fiber material with anti-aging, high strength, light weight, corrosion resistance, physical performance is extremely stable and so on. Its tensile strength of steel can reach 7-10 times, but it accounts for only less than 25% of the steel. It was black filamentous, small diameter, easily broken, can not be used alone. Only after the carbon fiber impregnated with resin after it is made using a special process of composite fiber alignment to apply. Finished sheets are generally divided into CFRP and carbon fiber. CFRP carbon fiber than randomness. Advantages of carbon fiber reinforced: 1, excellent chemical stability of carbon fiber materials. The material can be a good building structure to enhance the ability to adapt to the external environment, to extend the life of the building structure. 2, excellent physical and mechanical properties of carbon fiber materials. Excellent physical and mechanical properties of the material so that it can be effectively applied to the structure of bending, shear, compression, fatigue, seismic, wind, crack and deflection control reinforcement works, and you can get an excellent complement reinforcement strong effect. 3, light weight carbon fiber material, a high strength, the structure may be reinforced by using it after decoration, reinforcement without leaving traces, do not affect the appearance of the structure. It is light weight, high strength characteristics makes it possible to reinforce the structure in case of a substantial increase in the volume and the structure does not change the shape of the structure. This is compared to other methods can not repair and reinforcement characteristics. 4. Paste the carbon fiber material reinforced concrete construction process technology is very simple and convenient. When it does not enable the large-scale projects at the reinforcement construction equipment, power tools only need a small operation. So it has less jobs, less labor, time is short, the advantages of quick progress in the construction. Because carbon fiber reinforced materials of construction technology convenience and simplicity, making it has great economic and social benefits, it is reinforced with carbon fiber material technology is ideal for reinforced concrete structure building materials. Carbon fiber reinforced material requirements: (1) carbon fiber composite materials: carbon fiber composites and fibers from the matrix composed of. Reinforced concrete structures of fibrous material used mainly in the following three ways: aramid fibers, carbon fibers, glass fibers. Features three composites are: a completely linear elastic stress strain, material yield point or plastic region does not exist. When using CFRP material reinforced concrete structure, the force required by the structural characteristics of the structure and the carbon fiber cloth material with adhesive paste to the component surface and orderly to achieve the characteristic use of CFRP structural deformation constraints and improve the structure of matter The purpose of the ultimate strength and load capacity. (2) the bonding material: Can you guarantee a common focus of CFRP and concrete work is the quality of the degree of bonding material properties. Adhesive material is also key power transmission pathway between both of them lies. We chose the adhesive material must have sufficient toughness, it will not lead to brittle cracking concrete bond failure, and must have sufficient strength and rigidity, can guarantee to pass between carbon fiber and concrete shear. Reinforced concrete structure due to the construction environment engineering unrestricted, so the bonding material and carbon fiber material must be the same, can adapt to the harsh natural environment. CFRP construction requirements and processes (1) pre-construction preparation work, the base surface treatment requires CFRP pasted before the concrete is required before use grinders to clear and polished concrete surface deterioration layer structure; basal plane dislocation concrete structures and protruding parts to be polished, corner site should be polished with protruding parts, parts to be chamfered corner; the cracks in part to inject epoxy paste repair. Cleanup concrete surface: the first with a wire brush to brush away loose surface scum, then use compressed air to remove dust; then wipe the surface, rinse with water can also be used, but must be carried out to ensure that the construction of the next process to fully dry after the concrete surface . Shaoyang reinforcement company to undertake professional anchorage reinforcement increases section carbon fiber reinforcement bonded steel reinforcement reinforcement reinforcement works. (2) Paste construction requirements A, the need for reinforcement of concrete structures base requirements: CFRP reinforced concrete structures with CFRP technology is dependent on the structure of the surface of the paste is efficient, it requires strength grade concrete base shall not be less than the C15. At the same time asked to be reinforced concrete structure has a good protective layer, and the base surface should be smooth. For the structure of skin, peeling, corrosion, cracks and other surface defects and severe carbonation, you must first repair construction deal. B, CFRP Paste: When CFRP reinforced concrete structures, require the use of multiple layers of thin cloth paste method to ensure adequate infiltration and adhesive materials. For flexural members, the best in the tension zone axially paste CFRP reinforcement, and anchoring the necessary action in the vicinity of the ends of the main section of the fiber direction. C, CFRP lap and truncation: When pasting CFRP reinforced concrete, because CFRP and concrete bond stress focused on the ends of 10cm range, damage resulting bond is brittle, so you must take encountered CFRP When connected, lap length must not be less than 10cm. Lap site requires members must avoid stress maximum area range, while overlapping the ends must be smooth and no warping. D, engineering and supporting the selection of CFRP bonding material, manufacturers must provide material inspection certificate and certificate. 3. Paste Reinforcement Materials Quality Control should be strictly controlled in the construction of (1) with the control stick knot material than cement paste with a mix of materials must be strictly controlled, it is key to strengthening the quality and effectiveness of the paste can be guaranteed link in strict accordance with the requirements when using the ingredients mix preparation. (2) Construction of the temperature control epoxy curing more slowly at low temperatures, generally straight choice at 15 ℃ -28 ℃ temperature and (3) should be kept under the molding pressure of the conditions needed for construction. If you encounter construction at low temperatures, heating conservation measures must be taken. When reinforced concrete slab, mostly carried out on the bottom beam, bottom paste. If insufficient pressure is applied molding, it will cause bond between the concrete and not close enough, resulting in a reinforcing layer material shedding, will affect the reinforcement effect. (4) glue stick control requirements apply evenly to avoid the formation of voids or unglued, should be forced out of the bubble generated Calibrating, otherwise it will affect the reinforced concrete structure effect, resulting in some parts of the bond is not good cause These parts of the phenomenon of stress concentration in the use of concrete structures, causing damage to concrete structures.
