Abstract

PURPOSE: To improve the efficiency in execution of work by a method wherein a through hole is provided vertically between bases on the right and the left, and after a base board made up by connecting the right and the left bases with connecting parts is laid, concrete is cast with forms provided and bar arrangement for a rise part made to the through hole. CONSTITUTION: After a base board 10 is laid on a ballast layer compacted horizontally, a form 24 for the inside on a lot is mounted on a form-carrying part 15A on the base board 10 and fixed with a hook 53. Then, reinforcements such as unit reinforcing bars 55 are erected at the center of a part that becomes a rise part 22 of a footing. Then, lower ends of the reinforcing bars 55 are inserted into through holes provided vertically on the base board 10. After a form 24 for the outside is mounted on a form-carrying part 15B and fixed, the upper ends of the forms 24 for the inside and the outside are fixed with square timbers 59 or the like. Furthermore, a rise part 22 is formed with concrete placed between the forms 24. As the connecting surface between the rise part and the base board becomes large, strength can be improved, and term of works is shortened while the cost can be reduced.

The upper end of 24 is fixed by nailing it with a square member 59 as shown in FIG. 7E or 8, or is fixed with an anchor bolt fixing metal fitting 58 having a U-shaped cross section as shown in FIG. Therefore, since the upper side of the unit reinforcing bar 55 is tightly connected with the anchor bolts 57, the foam band for fixing the form is unnecessary as in the conventional case, and the rising edge generated by the conical protrusion formed on the foam band of the concrete panel is eliminated. It is not necessary to fill in the portion 22.
