|Title:||3D FIBER-REINFORCED COMPOSITE, AND CONCRETE COLUMN REINFORCEMENT STRUCTURE AND REINFORCEMENT METHOD USING SAME|
The present invention provides a 3D fiber-reinforced composite comprising: a reinforcing support member; and a reinforcing fiber member which is integrally embedded in the reinforcing support member and is formed to have a 3D pattern structure so as to support the reinforcing support member. According to the above description, the 3D fiber-reinforced composite and a shear key means are configured to be assembled to each other, and thus can be easily coupled and assembled, so that the construction time can be shortened, and constructability and workability can be improved due to the easy coupling and assembly. In addition, the 3D fiber-reinforced composite is formed into a precast product, so that construction at the site can achieve uniform quality and there is no need to ensure a wide space during the construction, compared to a construction method in which a reinforcement structure is constructed on-site. Further, since the 3D fiber-reinforced composite is assembled and coupled at the site after being manufactured in a manufacturing factory, difficulty in quality control due to construction at the site can be resolved.
