Hangzhou Strengthened by CFRP

Strengthened by CFRP reinforcement construction technology nationwide service hotline 18616785871 Hanjing warmly welcome you to negotiate cooperation the country to undertake professional: anchorage reinforcement, bonded steel reinforcement, crack reinforcement, Strengthened by CFRP, school seismic reinforcement, bridge repair and reinforcement, tunnel reinforcement workshop reinforcement, floor crack reinforcement, hotel transformation reinforcement structure 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, seal rubber, plastic repair; warmly welcome you to negotiate cooperation! The company is committed to structural reinforcement materials research and development, production and sales, reinforcing construction in one integrated company, the main products are: anchorage glue, glue stick steel, potting compound, pouring glue, carbon fiber plastic, carbon fiber, sealed plastic , repair glue; sales agent Hilti anchor adhesive; pillar floor crack Strengthened by CFRP construction program a material 1, the use of carbon fiber sheet to 300g / m, calculating 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, the elongation is not less than 1.5%. 2, A-grade carbon fiber sheet to use glue, relevant indicators should be consistent with "reinforced concrete structure design specifications" GB50367-2006 in the relevant provisions of 4.5.3. 3, carbon fiber cloth factory certification is required, the underlying resin, leveling material, impregnating resins must be in accordance with manufacturers required to configure the same manufacturer. Second, rehabilitation with CFRP laminates technical requirements of construction, concrete surface reinforcement design process according to the site location, the pasted surface of the concrete structure should be polished smooth, remove surface laitance, oil and other impurities, until completely exposed concrete structure of the new surface. Corner pasting the column should be treated lead angle and polished into a circular shape, an arc radius of not less than 20mm, the concrete surface should be clean and dry. 2, shall be prescribed in the process resin primer or configure the underlying resin. The underlying resin using roller brush evenly on the concrete surface, preferably in the bottom surface of the resin after touch dry, the next step of the construction as soon as possible. 3, leveling process configuration leveling material shall be prescribed in the process, to deal with the concrete surface smooth recessed portion filled with leveling material should not have corners. The corner leveling material should be used to repair a smooth arc, not less than 20mm. Third, the CFRP SHEETS 1, cut to size with carbon fiber sheet design requirements; 2, according to the process prescribed preparation impregnated plastic, and evenly to paste parts; 3, column posted using the full method of construction, pasting CFRP lap joints should be overlap of not less than 100mm, each lap joint construction should be shifted positions overlap. 4, hand soft reduction carbon fiber cloth 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 with carbon fiber sheet when rolling can not damage; 5, carbon fiber the surface of resin-impregnated cloth evenly; 6, after the construction finished CFRP, wipe the surface of grout to be protective. Fourth, inspection and acceptance 1. CFRP actually pasting area of ??not less than the design area, the position deviation should not exceed 10mm. 2, the bond between the quality of CFRP and concrete, usable hammer gently tap or hand pressure carbon fiber sheet to the surface of the method to check, the total effective area of ??not less than 95%. When CFRP hollowing area not larger than 10 square centimeters, can be needle dispensing method of repair. When hollowing area of ??more than 10 cm2, should be hollowing parts with carbon fiber sheet sheet removal, re-labeled the same amount of overlap of carbon fiber sheets, lap length not less than 100mm.
