Strengthened by CFRP company Fangchenggang

15399888199 Lo The company has qualified and professional reinforcement construction team! Fangchenggang strengthening the company's main business: building structure reinforcement, rehabilitation with CFRP laminates, bonded steel reinforcement, anchorage anchoring, filling cracks, tunnel reinforcement, reinforcement of reservoir dams, culverts reinforcement, dam reinforcement, chimney reinforcement, grouting, house Strengthening structural transformation, seismic reinforcement and other reinforcement Engineering and corrosion, waterproof plugging, seismic, new and old concrete interface handling the construction work and technical advice static concrete cutting and other project works. Fangchenggang reinforcement company used carbon fiber reinforcement Reinforcement Reinforcement Project name suggests are for existing buildings or structures, both in terms of design or construction has its particularity, there is a big difference compared with new construction, mainly as follows: First reinforcement project has its unique demolition and clean-up work; second, reinforcement design is necessary to include further checking and structural adaptation of the original structure of the judge in the case to determine the required reinforcement reinforcement calculation, but also considering the old and new structures strength, stiffness, balance and coordination synchronized work and other aspects of normal life; Third, strengthening the construction site often subject to various conditions about the system, such as: the construction site work surface is narrow, blocking and interfering with other members, etc. In addition, reinforcement works much has been put into use, there must be requested without affecting less impact on production, the implementation of reinforcement construction of the case, this will inevitably increase the difficulty of reinforcement construction, if necessary, should be reinforced construction segment, in phases, even Certain factors that may cause not expected construction disruption. Member external sticky carbon fiber reinforced method is stress analysis calculations and force characteristics according to the structural member, the application of carbon fiber supporting resin member affixed to the corresponding parts of the outer concrete strength force does not meet the requirements to achieve the bearing capacity to meet the requirements of a member reinforcement methods. Its principle is to use the shear strength of reinforced its supporting resin concrete member carrying the load transfer to the carbon fiber, carbon fiber and pasting after making the original RC members have to bear the load forces. Features 1. 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-resistant, durable Good performance 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. 2. high tensile strength, is 7-10 times the same cross-section steel. 3. Light weight, density is only 1/4 of ordinary steel. 4. durability, chemical corrosion and damage can impedance harsh environment, climate change. 5. reinforcement construction convenient, time-saving section, easy to guarantee the quality of construction. 6. 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. Applications 1. concrete structures, bridges and buildings of beams, columns, panel reinforcement. 2. tunnels, harbor facilities, chimneys, warehouses, factories reinforcement. 3. Concrete by salt damage, bridges and structures of river protection and reinforcement. The principle of high tensile strength carbon fiber composite reinforced with epoxy prepreg become material (unidirectional continuous fiber); the structural epoxy adhesive is pulled along the direction perpendicular to the fracture direction or attached to reinforcement to form a new complex, the reinforcing material with the original pasted together by reinforced concrete crack or shear force increases capacity of the structure, improve strength, stiffness, crack resistance and elongation of the structure. Application Method / 1. concrete surface treatment 2. The surface of the concrete structures incomplete, damaged part removed. 3. After the tick chisel, clean up and missing parts components exposed tendons, repair, restoration. 4. Crack Repair: Aperture cracks less than 0.2mm, and brushing the surface with epoxy resin seal; cracks greater than 0.2mm pouring with epoxy. 5. polished: the component surface projection (transfer of parts of concrete structures, then hew templates, etc.) polished smooth surface of the component after the repair smooth as possible. 6. clean polished surface of the component and make it fully dry. 7. defect site with a good brushing primer primer (binder), even with brushing the concrete surface at the defect site. 8. repair with epoxy putty repair surface defects on the surface of the component surface defects surface member is a very important step, points are as follows: 9. putty main agent, curing catalyst inlet, a curing agent according to a predetermined ratio weighing accuracy, load container, blender and mix well. 10. A member dishing site filled with epoxy putty to repair to the surface roughness. When using epoxy putty in incomplete repair, to the temperature above -5 ℃, relative humidity less than 85% for construction. After Putty Scraping the surface roughening irregularities still exist, should then sanded smooth. 11. Brushing the end of glue with a good primer (binder), even with a roller brush to require bonded concrete surface. 12. Before CFRP CFRP material, you should first confirm the paste surface is dry. Temperature above -10 ℃, relative humidity RH> 85%, if no effective measures are not construction. To prevent damage to the carbon fiber, carbon fiber materials transportation, storage, cutting and pasting process. The steel ruler and wallpaper knife cut a predetermined size carbon fiber material, each length is generally not more than 6m appropriate. In order to prevent material damage in the storage process, cutting the amount of material shall be subject to the same day the amount of crop. Carbon fiber longitudinal joints must overlap at least 20cm. The parts should be painted resin, carbon fiber lateral overlap is not required. Its construction elements process is as follows: 13. The paste resin main agent, curing agent and a curing agent urged the proportion should be required weighing accuracy, into the container, stir with a stirrer. Reconcile the amount of time should be spent within the available time prevail. 14. pasting between carbon fiber and resin try not to have air. Available Rolla (special tools) along the fiber direction rolled several times in the carbon fiber material, immersing the resin infiltration of carbon fiber. 15. After curing CFRP material, nature conservation need 1-2 hours to reach the beginning of curing, should ensure free from outside interference and collisions during curing. 16. If the reinforcement member needs painting fire, the fire-resistant coating can be painted after the resin is cured. After the initial resin coating should be cured, and should comply with the relevant standards and regulations used in construction paints. This information is standing. Tel 15399888199 Lo!
