Reinforcement material of carbon fiber reinforcement construction points for attention

Reinforcement material of carbon fiber reinforcement, carbon fiber materials used for strengthening concrete structure repair research began in the 80 s the United States, Japan and other developed countries. The technology in our country started very late, but with the rapid development of China's economic construction and the cause of the traffic, a substantial part of existing buildings due to the low standard of design load caused problems left over by history, some construction due to the change of the use function, it is difficult to meet the needs of the current specification use, need repair and reinforcement. At present there are a lot of common reinforcement methods, such as enlarging section method, the seismic reinforcement method, sticking steel strengthening method, carbon fiber reinforcement method, etc. Repair the structure technology of carbon fiber reinforced plastics is after enlarging concrete section, sticking steel strengthening technique is a new type of structure. Follow below zhengde building materials to understand the building reinforcement material of carbon fiber reinforcement construction matters needing attention: 1, paste, fixed carbon fiber composite reinforcement concrete structure should be familiar with the technology of construction technology of professional construction team, and the construction scheme and technical measures should be reinforced to repair. 2, carbon fiber reinforcement construction must follow the following process. 3, the construction should be under 5 ℃ environment temperature conditions, and should be consistent with supporting the construction use temperature of the adhesive. Should be used when the environment temperature is lower than 5 ℃, is suitable for low temperature environment supporting adhesive or use heat treatment measures. 4, should be considered during the construction of environmental humidity on the negative impact of the adhesive curing. 5, before the surface treatment and pasting carbon fiber sheet, should take the strengthening design pay-off positioning. 6, carbon fiber adhesive preparation should be used according to the product description rules of ratio of weighing put in container, using mixer even mixing to colour and lustre is uniform. Stir in container and agitator can not have oil and impurities. Should be determined according to the actual environment temperature adhesive amount of each batch, and strictly control the use time according to the requirements of use.
