    Abstract: A textile-reinforced concrete road paving apparatus and a method of repairing concrete road pavement can minimize use of construction equipment by using the textile-reinforced concrete road paving apparatus integrally formed to consecutively cut concrete, dispose a reinforcement material, and construct a repaired cross section so as to reduce a construction period, thereby remarkably reducing construction costs. Further, a textile grid reinforcement material, which is a noncorroding reinforcement material, is applied to form the repaired cross section of the concrete road pavement so as to prevent concrete from being detached due to corrosion. Further, a textile reinforced grid is precisely disposed at a required position, and thus the thicknesses of the primary and secondary concrete pavement are precisely adjusted, and thus construction precision can be increased.

    Abstract: The present invention relates to a facility comprising: a fixed frame fixedly installed on an outer wall of a veranda or a balcony of a high-rise building; a foldable evacuation box which can be unfolded in the form of a rectangular parallelepiped having an open top side and has and evacuation door on a side thereof; a fall prevention and evacuation means which can be structurally changed to an emergency stairway for fire evacuation; an evacuation box locking means which allows the foldable evacuation box to be unfolded in a rectangular parallelepiped form; a locking means which holds and fixes the fall prevention and evacuation means to the fixed frame; and an entry prevention door which prevents an evacuee from entering inside a veranda or a balcony from the foldable evacuation box through the fixed frame.

    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.
