CONSTRUCTION METHOD FOR INTEGRALLY PLACING CONCRETE FOR FOUNDATION AND DIRT FLOOR

摘要

PROBLEM TO BE SOLVED: To provide a construction method for integrally placing concrete for a foundation and a dirt floor for placing the concrete for a continuous footing and a dirt floor adjacent to the continuous footing on the same day without using any special form.;SOLUTION: This construction method for placing concrete for a continuous footing 6 and concrete 9 for a dirt floor adjacent to the continuous footing 6 includes: an excavation process of excavating an excavation recess 5; a form construction process; a basic concrete placing process; and a dirt floor concrete placing process. The continuous footing 6 is constituted of a base part 7 and an erected part 8. The concrete 9 for a dirt floor includes: a flat part 10 laid in a level which is higher than the base part 7 of the continuous footing 6 and laid in a level which is lower than the upper end of the erected part 8 of the continuous footing 6; and an inclined part 11 extended obliquely downward from the edge on the continuous footing 6 side of the flat part 10 and continued to the side surface of the base part 7. In the form construction process, basic forms 1, 2 for placing the continuous footing 6 are installed in the excavation recess 5 in such a configuration that a portion being the side surface on the dirt floor concrete 9 side of the base part 7 is opened.;COPYRIGHT: (C)2013,JPO&INPIT
