Prestressed carbon fiber board has high tensile strength, good corrosion resistance, shock resistance and impact resistance, so they are widely used in the reinforcement of houses, bridges and concrete. But as an emerging reinforcement material, how can it be applied to achieve the desired reinforcement effect?
In fact, it is important to master the correct construction process. Firstly, the concrete surface treatment is carried out. Then, at the position where the carbon fiber board tensioning end and the fixed end member, drilling holes and installing high-strength screws according to the design drawing requirements. After the screw is solidified to reach the design strength, the tensioned end and the fixed end steel member are started to be installed → carbon fiber board adhesive surface is wiped clean with acetone before bonding. Applying adhesive to the contact surface of the carbon fiber board and the beam bottom. Applying adhesive to the contact surface of the anchor bottom plate and the beam bottom. Installing the carbon fiber board → tensioning the carbon fiber board and observing the deflection change of beams → After the tension is completed, a 5mm thick adhesive is used as a carbon board protective layer on both sides of the carbon fiber board → a layer of adhesive is applied to the nut of the fixed anchor bolt. A layer of anti-rust grease is applied to all metal parts, and then the tensioned end and the fixed end anchor cap are installed. The caps on both sides of the reinforced beam bottom are protected by high-strength and high-bonding mortar protection paint.
In addition, pre-stressed carbon fiber boards with good quality are also important. Nanjing Mankate prestressed carbon fiber board is of high quality and is underwritten by Ping An Insurance. It is made of imported carbon wire and used with resin that has been aging for 50 years. It has complete specifications. I believe you can choose your satisfactory product.
