BENT PC FOUNDATION FORM, AND CONSTRUCTING METHOD EMPLOYING THE SAME

PURPOSE:To make construction of lightweight foundation forms executable in shortened term of works with reduced man power, and to contemplate therewith environmental protection with consumption of resources saved. CONSTITUTION:A bent PC foundation form 10 is formed of a bent PC board 12 and a pair of riser PC boards 14 that are erected above the bent PC board 12. In the bent PC board 12, a bottom part 12a and side parts 12b on both sides are connected with one another so that they can be bent. Both of the side parts 12b are erected so that the bent PC board can be formed in a U shape, and a pair of hollow part-forming members 16 made of styrene foam in rectangular section are attached to both of the upper ends of the side parts 12b on both sides. A plurality of flat bars 18 are laid, spanning a space between the front ends of both of the side parts 12b forming the U shape, at appropriate intervals in the longitudinal direction. The paired riser PC boards 14 and 14 are attached, facing each other, on the upper middle part over the flat bars 18 through holding parts 20.
