CARBON FIBER REINFORCEMENT AND GRID TYPE FIBER REINFORCEMENT AND REINFORCING METHOD OF CONCRETE STRUCTURE USING THE SAME

摘要

The present invention relates to a grid-type fiber reinforcement and a method for reinforcing a concrete structure using the same, which comprises a grid type fiber reinforcement sheet that has a first and a second reinforcement fiber coupled to an upper side of a non-woven fabric in a grid shape; and a grid type fiber reinforcement member having excellent strength, stiffness, and adhesive strength with the concrete structure by being consisted of a grid type fiber reinforcement sheet for an anchor that passes through the grid-type fiber reinforcement sheet in order to be inserted in an anchor hole of the concrete structure. The grid-type fiber reinforcement sheet comprises the non-woven fabric that is attached to a concrete surface by an adhesive material; multiple first reinforcement fibers that are attached to the upper side of the non-woven fabric in one direction at a certain distance; and multiple second reinforcement fibers that are attached to the upper side of the non-woven fabric, to which the first reinforcement fibers are attached, in a vertical direction against the first reinforcement fibers at a certain distance. The band-shaped fiber reinforcement sheet for an anchor is impregnated with the adhesive material, whose one end is inserted and adhered to the anchor hole formed on the concrete structure through the non-woven fabric between the first reinforcement fiber and the second reinforcement fiber of the grid-type fiber reinforcement sheet, and the other end is spread, adhered, and fixed to the outside of the grid-type fiber reinforcement sheet.
