PURPOSE:To simplify the carrying-in operation of materials for a strip footing by a method in which other vent ports and the rising portion of strip footing for general foundation are formed by leaving a vent port serving as a path through which materials are carried in, and lastly, the vent port serving as the path is constructed. CONSTITUTION:A strip footing 11 is constructed of vent ports 11a, 11b, 11c, and 11d and a general fundation 11e. The vent ports 11a, 11b, 11c, and 11d are provided with a vent port 12 having a vent port iron-bar set unit 16 with an iron bar lattice 15. When concrete is placed for the vent port 11a and the general foundation 11e, plates (not illustrated) are laid across excavated trenches (not illustrated) for the vent ports 11b, 11c, and 11d to form a path 19, and by utilizing the path 19, materials necessary for constructing a strip footing 11 are carried in. After the completion of construction of the foundation 11e and the vent port 11a, the vent ports 11b and 11c are constructed and lastly the vent port 11d is constructed to complete the construction of the strip footing 11. |
