Shanghai Wang Hao Jianye Composites company in 2009 began to introduce Japan's carbon fiber material bridges and housing structure reinforcement construction, has experienced construction team, the company specializing in the production and sales of carbon fiber reinforced materials, with special strengthening qualifications, to undertake strengthening works. Welcome to inquire and cooperation! I. Introduction Carbon fiber compared to traditional concrete sections or increase concrete bonded steel reinforcement, space-saving, simple construction, no fixed-site facilities, easy to guarantee the quality of construction, substantial increase in the structure size and weight, corrosion resistance, durability and other characteristics. In addition, using this construction method can greatly improve the life of the building, reducing the cost of reinforcement. Thus, carbon fibers as a reinforcing material landmark, has become widely accepted and attention. ? (1) high tensile strength, is 7-10 times the same cross-section steel. ? (2) Light weight, density is only 1/4 of ordinary steel. ? (3) durability, corrosion and harsh environments can impedance, climate change destroy the chemical. ? (4) construction of convenient, time-saving section, easy to guarantee the quality of construction. ? (5) for a wide range of concrete structures, steel structures, wooden structures can be reinforced. Can greatly improve the member carrying capacity, seismic performance and durability. Second, the performance indicators of various carbon fiber sheets Specifications Physical Performance Table Name Type Type fiber volume g / m Length m Width cm design thickness mm Tensile strength N / mm2 modulus of elasticity N / mm2 yielding% when high-strength carbon fiber sheet to Ⅰ Level 200 25/30/33/50 100 0.111 ≥3400 ≥2.40 × grade 105 Ⅰ 300 25/30/33/50 100 0.167 ≥3400 ≥2.40 × 105 Ⅱ grade 400 25/30/33/50 100 0.111 ≥3000 ≥ Level 2.10 × 105 Ⅱ 600 25/30/33/50 100 0.167 ≥3000 ≥2.10 × 105 Notes: (1) Tensile strength / elastic modulus to GB50367-2006 "reinforced concrete structure design specifications" as a reference ?? (2 ) any question of carbon fiber content, CFRP size and elastic modulus, please contact me? (3) Special magnitude equal size requirements, according to the specific circumstances of ordering the production of three main features reinforced construction method of carbon fiber added concrete steel Paste feature to paste the severity of reliable quality unreliable construction of artisanal work heavy machinery large surface area of ??the small four easy difficulty, the construction process 1, the construction to draw up construction plans and construction plans, carbon fiber sheet used to deal with, and the supporting resin, equipment make other preparatory work before construction. 2, remove the reinforced concrete surface treated member surface flaking, loose, cellular, and corrosion deterioration of concrete, exposed concrete structure layer and surface repair of prosthetic material flat. According to the design requirements of the cracks pouring or closed process. 3. The provisions of the preparation process and primer or resin formulated by suppliers underfill resin, the resin layer evenly on the concrete surface. After the resin surface to touch in the dry construction immediately to the next step. 4, the preparation and repair uneven leveling material at the site of the sunken concrete surface with leveling material to fill the flat, the corner apply leveling material to repair a smooth arc, radius should be not less than 20mm. 5, CFRP sheets ① cut to size according to the design requirements of the Carbon Fiber Sheet; ② formulated resin-impregnated and uniformly applied to the member to be pasted; ③ rolling several times along the fiber direction, exclude air, fully saturated with resin impregnated with carbon fiber sheet; ④ CFRP surface evenly impregnated with resin. 6, surface protection according to the provisions of the relevant specification process, and to ensure a reliable bond between the protective material and carbon fiber sheet.
