Abstract:
PROBLEM TO BE SOLVED: To provide a forming method, a reinforcement structure, and a reinforcement method of a man-through-hole as well as a metal structure for a man-through-hole through an erected wall of a housing foundation, of which a size is large enough for a person to pass through and which has strength and easiness of construction.SOLUTION: A method is to easily construct a man-through-hole in an erected wall 210 of a housing foundation using a metal structure 100 for the man-through-hole formed of a frame case body, which has a man-through-space large enough for a person to pass through, by forming a frame body 110 with an upper open portion configured with a side metal plate 111 and a bottom plate 112 and connecting an open face with a trapezoid-shaped beam 120 to ensure a passage under a floor. Steps of the method comprises: first, previously securing the metal structure 100 for a man-through-hole at a predetermined place in a concrete form constituting an erected wall 210 of a housing foundation; injecting concrete to a top level of the erected wall 210 of the housing foundation as it is; and removing the concrete form to construct a desired man-through-hole 300 ensuring a through space of a through plane of the man-through-hole 300 at the erected wall 210 of the housing foundation 200.SELECTED DRAWING: Figure 1
