Abstract: Provided are a textile-reinforced concrete structure using a textile grid fixing device and a construction method therefor. A textile grid is precisely disposed at a predetermined position between a mold and a main reinforcing bar using a textile grid fixing device so as to be prevented from being moved by a pouring pressure when concrete is poured, and thus a textile-reinforced concrete structure can be precisely constructed. The textile grid fixing device is fixed to one side of the mold, and the textile-reinforced concrete structure is constructed using the textile grid fixing device such that fine cracks are suppressed from being generated on a surface of concrete. Further, a surface of a concrete structure is protected from an external environment when the textile-reinforced concrete structure is constructed so that a covering thickness of concrete can be reduced, and thus, the textile-reinforced concrete structure can be economically constructed.

Abstract: Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.
