PURPOSE:To construct a fence or retaining wall, etc., in a short period by a method in which plate structural parts are set in parallel at a given interval on the bottom of a trench, concrete is placed between side plates, and the lower parts of the plate structural parts are integrated to form a strip footing. CONSTITUTION:In the construction site of a fence or retaining wall, etc., a trench 10 is excavated, broken stones 8 are laid, and leveling concrete 4 is placed. Side plates 3 are set in parallel at a given interval on the concrete 4, and reinforcing bars 3b extending inwards from right and left-side plates 3 are connected with cross reinforcing bars 5. A footing 2 is placed on the side plates 3, prefabricated fence parts 1 are laid, spacers 7 are thrust through the holes 1c of the fence parts 1, and the joints of the side plates 3 are pressed from outside by the fastener plate 7a of both sides. Concrete is placed between the side plates 3 to form a strip footing 6, cement mortar is packed into the vertical holes 2a of the footing 2, and after the concrete hardens, the trench 10 is back-filled with soil to complete the construction work. |
