PURPOSE:To make easier construction work by a method in which pipy fixing tubes are vertically fixed to tips of support legs fixed into a Y-shaped form toward the horizontal direction, a flange is fixed to the central upside of the tubes, and reinforcing bars are provided to the tubes in an insertable and coupling manner. CONSTITUTION:Three support legs 2 consisting of angular pipes of equal length are contacted into a Y-shaped form toward the horizontal direction, and a flange board 3 with through hole is welded to the upside of the contact portion and a cover board 5 is welded to the downside. A fixing tube 6 consisting of an angular pipe is vertically fixed to the end of each leg 2 to form a foundation body 1. Both ends of a cross lever 11 corresponding to the diagonal inner width of the rectangular hole 10 of the tube 6 are upwardly bent in a mutually crossed manner to form parallel vertical levers 12. Coupling ends 13 are formed on the upper ends of the cross levers 11 to form a reinforcing material 9. In such a way that two diagonal lines of the holes 10 are crossed in relation to the tubes 6, paired reinforcing steel bars 9 are inserted. |
