Product Description
1, reinforcement principle and composition
The basic principle of prestressed CFRP reinforcement is to make it to a higher stress level and to exert a certain strength in advance, so as to realize the effective utilization of its high strength properties, before the load stress transmitted by the CFRP bearing structure. In this case,
Prestressed CFRP reinforcement system consists of three parts: anchor, carbon fiber, structural adhesive.
2, Prestressed carbon fiber reinforcement Advantages:
After prestressing the CFRP sheet, it is pasted to the tensioned surface of the reinforced structure. After the structural adhesive is fully cured, the sheet is released, and the structural adhesive is prepared by using the structural adhesive. After the pre-stressed carbon fiber is bonded, the carbon fiber reinforcement method is combined with the external prestressing reinforcement method. The transmitted shear stress exerts preloading stress on the tensioned zone of the stiffened member.
2.1, variable passive reinforcement for the active reinforcement. The strength of carbon fiber sheet can be brought into play in advance, there is a greater strain before the second force, so as to effectively reduce or even eliminate the phenomenon of strain lag of CFRP sheet to achieve better reinforcement effect.
2.2, the reverse bending moment produced by prestressing can be offset by part of the initial load to improve the bearing capacity of the use phase, so that the original crack width of the component reduced or even closed, and limiting the emergence of new cracks, thereby enhancing the stiffness, Reduce the deflection of the original component, improve the performance of the use phase.
2.3, deformation of carbon fiber = deformation caused by the initial deformation + load, and corresponding to the deformation of the two parts of the structure of plastic shear deformation were distributed in the two ends and cross-region, making the structure of plastic shear deformation distribution is more uniform , Can effectively avoid the bond damage.
3, Application
3.1, large span steel structure, reinforced concrete bridge reinforcement, enhance the carrying capacity, widely used in prestressed / non-prestressed bridge structure;
3.2, steel structure, reinforced concrete beam girder, box girder, T beam bending reinforcement;
3.3, steel structure, reinforced concrete bridge crack control reinforcement;
3.4, civil construction, industrial plants and other buildings, large-span structural beams, plates, bending reinforcement, crack control reinforcement.
1. High strength, good efficiency
Carbon fiber plate has excellent physical and mechanical properties, tensile strength is more than 10-15 times of ordinary steel, elastic modulus is better than steel, excellent creep resistance, corrosion resistance and seismic resistance. It is very suitable for rebar concrete structure reinforcement and repairment and maintenance.
2. Light weight, excellent flexibility
Carbon fiber plate is stronger than steel, but the weight is only 1/5 of steel, higher toughness, and can be coiled up for extensive length supply without overlapping.
3. Convenient installation, construction quality is easy to assure
It can be operated in wet conditions without large-scale construction equipment, without on-site fixed facilities. Carbon fiber length can be arbitrarily cut, the construction is simple and short construction time. This kind of material is allowed to overlap, does not require pre-processing, and its working procedure is convenient.
4. Good durability and corrosion resistance
Anti-acid, alkali, salt, and corrosion in atmospheric environment, no need of regular maintenance. It has protective effect for internal concrete structure and achieves dual purpose of reinforcing and mending.
In addition:
1) carbon fiber plate is more applicable for prestressed reinforcement, bringing into full play the role of high-strength of carbon fiber materials;
2) Construction is simple and efficient, and the quality guarantee become easy;
3) The carbon fiber plate is easy to keep straight and smooth than carbon fiber sheet, so it is more beneficial for carbon fiber to take effect;
4) One piece of 1.2mm thickness carbon fiber plate is equivalent to 5 pieces of carbon fiber sheet;
5) Carbon fiber plate is more suitable for masonry wall reinforcement compared with carbon fiber sheet;
6) Carbon fiber-glass fiber composite plate not only can improve the elongation of concrete structure, but also can reduce the cost of carbon fiber plate.

3.Bridge piers, piles and other column reinforcement;
4.Chimneys, tunnels, pools, concrete pipe reinforcement.
•The reinforcement effect of one piece of carbon fiber plate is equivalent to 4-8 pieces of carbon fiber sheet
•Carbon fiber plate is light in weight and easy for use, making installation simple and construction efficiency high
•The strength and rigidity of carbon fiber plate is high, so there is no need to paste the structure overall
•Compared with steel plate installation, it requires only simple scaffold, no need of welding procedure, short construction time
Storage:
Carbon fiber plate should be stored in dry and well-ventilated place and protect from sunlight.
Caution: Do not roll or drag carbon fiber plate if it does not have protective layer to avoid damaging the carbon fiber plate.
