Carbon fiber reinforcement construction
Application scope of carbon fiber technology construction flow chart Reinforced concrete structural beams, slabs, columns, walls And joint reinforcement, crack treatment of masonry structures, reinforcement of bridges, tunnels, chimneys, silos and other structures. It mainly includes carbon fiber cloth reinforced beams and plate positive section bearing capacity. Carbon fiber cloth reinforcement strengthens the load-bearing capacity of beams and plates at inclined sections. Carbon fiber cloth reinforcement strengthens the bearing capacity of the normal section of reinforced concrete columns. Carbon fiber cloth increases the seismic resistance of reinforced concrete columns. Carbon fiber cloth repairs temperature cracks in brick house walls. Bonded carbon fiber reinforcement is a construction process in which carbon fiber is bonded to the surface of the structure using a special adhesive. Although it is an emerging construction technology, it has been widely used. The operation process includes concrete surface grinding, carbon fiber cleaning, carbon fiber cutting, carbon fiber pasting, etc. The thickness of carbon fiber cloth is divided into two types: and, and the weight is and. , Surface treatment and cross-section repair: First, use a grinder to treat the surface of the bonded structure until it meets the requirements (as mentioned above). If there are any defects, they need to be repaired and smoothed. If there is water leakage, it needs to be stopped and diverted. In short, the quality of surface treatment of the bonded structure directly affects the quality of reinforcement. , Coating and uneven trimming of the bottom surface. Prepare the bottom layer with glue and apply it. The thickness of the coating is determined according to the temperature and the specific conditions of the construction bonded components. Especially in winter, it is not suitable for construction when the temperature is below ℃ and it is not suitable for construction in rainy days. After the base glue has solidified, use a smoothing machine to smooth out the uneven areas to prepare for the next process. Attention should be paid to ventilation and labor protection at the site. , Carbon fiber patch construction, curing and surface coating When bonding carbon fiber (quality inspection has been carried out), first cut (or cut with a knife) the required size according to the requirements. For convenience such as storage, a length of two meters is generally suitable. . When pasting, try not to allow air to enter between the bonded carbon fiber and the adhesive, and the overlap of the carbon fiber sheets should be left above. It is best to leave a layer of it on for several hours to achieve the effect of defoaming and moisturizing. As the structural adhesive reacts and the viscosity increases until it solidifies, good results can be achieved by applying a second layer. It is best to apply one layer a day in winter. During its curing, it should be protected from rain and wind and sand. After curing, surface coating is performed as required to complete the construction.
