HYBRID FIBER COMPOSITE BAR AND STRENGTHENING METHOD OF CONCRETE STRUCTURE USING THEREOF

摘要

The present invention relates to a hybrid fiber reinforcing bar and an embedment-type reinforcing method for a concrete structure using the same. An objective of the present invention is to provide a hybrid fiber reinforcing bar which is formed in a bar shape, embedded in a concrete structure to increase strength and durability, and comprised of a fiber reinforcing material wherein the inside thereof and the outside thereof are different, and an embedment-type reinforcing method for a concrete structure using the same. The hybrid fiber reinforcing bar according to the present invention is comprised of a fiber reinforcing material wherein the inside thereof and the outside thereof are different, has a dual cross sectional structure, and is formed in a bar shape. The embedment-type reinforcing method for a concrete structure using the hybrid fiber reinforcing bar comprises: a step of acquiring the hybrid fiber reinforcing bar, then embedding the hybrid fiber reinforcing bar in at least one recess formed on a lower surface of a concrete structure to be reinforced in a longitudinal direction, filling the recess with an adhesive, and coating the recess filled with the adhesive and the surrounding area with a concrete protective finishing material.
