摘要

The present invention has been devised to solve the problems of the prior art, and an object of the present invention is to install a reinforcing sheet after chipping and rust prevention on the repair part of a concrete structure, apply a primer, and then fill the mortar, It prevents corrosion or separation of the mortar and reinforcement sheet filled in the repair part, and the reinforcement sheet is formed by mixing glass fiber and amarith fiber, and fixed with a pin or nail to improve the bearing capacity and the repair part It provides a method for restoring the cross section of a structure using a high-strength composite sheet made of glass fiber and aramid fiber to be firmly fixed, and a method for reinforcing earthquake resistance of a structure. According to the structure cross-section reinforcement method and the structure earthquake-resistance reinforcement method according to the present invention, the compactness of the hardened structure is strengthened by the mortar for repair and reinforcement, temperature cracking due to heat of hydration can be suppressed, and the fine powder contained in the binder By using additives, physical strength such as compressive strength of the repair and reinforcement surface is strengthened, and the adhesive strength with the concrete surface is strengthened to improve durability, water resistance, acid resistance and fire resistance (flame retardancy), which has the advantage of maintaining the repair and reinforcement effect for a long time. , It has excellent workability and workability because it enables rapid construction even when constructing tunnels, bridges, buildings, and railway structures subjected to shock or vibration. Since physical properties such as strength are strengthened, problems such as mortar falling off and insufficient durability and earthquake resistance can be solved. In addition, the strength of adhesion to the concrete surface is strengthened, so that durability and water resistance are improved, chemical resistance and water resistance are excellent, and resistance to Tokyo fusion and salt damage is excellent.
