Application of carbon fiber cloth

Reinforcement of building beam, column and floor structure; reinforcement of bridge pier and deck structure; reinforcement of tunnel chimney structure; corrosion and reinforcement of beach buildings. The purpose of using carbon fiber cloth is to improve the bearing capacity and ductility; for seismic structures, the effect of ductile carbon fiber cloth reinforcement in the reinforcement design is structural state deformation. The original structure stress cracks. The technical points of carbon fiber cloth reinforcement. The direction of the reinforcement is the same; the direction of the fiber should be perpendicular to the axial direction of the member when the shear reinforcement is used for the seismic reinforcement; the concrete strength grade should not be lower than C when the bending reinforcement and the shear reinforcement are used; when the bonded carbon fiber is used to reinforce the concrete column, The concrete strength level should not be lower than C; the effect of carbon fiber reinforcement mainly depends on the fiber bonding process, and the professional construction team should be responsible for the construction.

Unloading according to actual conditions and design requirements, this step is sometimes omitted) With a moderate unloading reinforcement effect, generally only live loads, such as personnel office equipment, etc., can be unloaded, and temporary construction loads should be minimized. Constant load unloading can be composed of jack pad top rod. The applied reaction force is easy to control, the stress is lagging, and it is more conducive to the coordinated force of the carbon fiber cloth and the original member, and the reinforcement effect is good. The configuration surface glue and cut carbon fiber cloth fiber cloth impregnating glue are AB components, which can be mechanically stirred. Small amounts can also be manually stirred with ΦΦ thin steel rods. Note that only mixing with a greasy knife does not guarantee uniform mixing). Use sharp scissors to cut the carbon fiber cloth according to the size required by the design, pay attention to neatness and uniformity, to avoid burrs.
