National CFRP manufacturers supply [Service Hotline: 139-1713-0703] Chen undertake professional nationwide: anchorage reinforcement, bonded steel reinforcement, crack reinforcement, CFRP, school seismic retrofit, maintenance and reinforcement of bridges, tunnels and reinforcement, plant reinforced floor crack reinforcement, strengthening the hotel renovation, construction Liangzhu Zi carbon fiber reinforcement, column reinforcement package angle perfusion; professional production: anchorage glue, glue stick steel, potting compound, pouring glue, carbon fiber plastic, carbon fiber, sealing glue, repair glue; warmly welcome you to inquire and negotiate! The company is committed to structural reinforcement materials research and development, production and sales, strengthening the construction of an integrated company, main products are: anchorage glue, glue stick steel, potting compound, pouring glue, carbon fiber plastic, carbon fiber, rubber seal repair glue; Hilti anchor adhesive sales agents; pillar floor crack CFRP construction program a material one, CFRP using 300g / m, calculate the thickness of 0.167mm, the tensile strength of the standard value of not less than 3000MPa, tensile elastic modulus of not less than 210000MPa, elongation of not less than 1.5%. 2. Class A CFRP using glue, relevant indicators should be consistent with "reinforced concrete structure design specifications" GB50367-2006 the relevant provisions in 4.5.3. 3, CFRP requires factory certification, the underlying resin, leveling material, impregnating resins must be in accordance with manufacturers required to configure the same manufacturer. Second, pasting CFRP construction technology requires a concrete surface treatment sites by positioning reinforcement design, structural concrete surface should be polished smooth paste, remove surface laitance, oil and other impurities, until completely exposed concrete structure of the new faces. Paste the corner at the leading edge of the column should be processed and polished into a circular shape, radius of not less than 20mm, the concrete surface should be clean and dry. 2, brushing the underlying resin craft regulations should configure the underlying resin. Using roller brush evenly on the bottom of the resin concrete surface should be in the bottom surface of the resin touch dry, the next step of the construction as soon as possible. 3, treatment should be prescribed in the process of leveling leveling material configured to deal with parts of the concrete surface depressions filled with smooth leveling material should not have corners. The corner leveling material should be used to repair a smooth arc, not less than 20mm. Third, paste CFRP 1, according to the size of the crop CFRP design requirements; 2, according to the provisions of the preparation process of dipping glue and paste evenly on the site; 3, the use of full-paste method of construction pillars and paste CFRP lap joints shall be lap of not less than 100mm, each lap joint construction shall be staggered position lap. 4. Gently press the CFRP hand affixed to the need to paste the location, to use special drum roll several times along the fiber direction, exclude air, fully saturated with resin impregnated carbon fiber roll when CFRP not damage; 5, carbon fiber surface cloth impregnated resin evenly; 6, after pasting CFRP construction finished, wipe the surface grout to be protective. Fourth, an inspection and acceptance, CFRP pasted area of ??not less than the actual design of the area, the position deviation should not exceed 10mm. 2, the bond between the quality of CFRP and concrete, usable hammer gently tapping or hand pressure CFRP surface inspection method, the total effective area of ??not less than 95%. When CFRP hollowing area not larger than 10 square centimeters, can be used needle dispensing method of repair. When hollowing area greater than 10 square centimeters, should be part of the hollowing CFRP sheet removal, re-labeled the same amount of overlap of carbon fiber sheets, lap length of not less than 100mm.
