MOLDING METHOD OF CONCRETE BASEMENT

PROBLEM TO BE SOLVED: To closely integrate a wall concrete and a floor concrete into a unit to promote waterproof efficiency between them. SOLUTION: An outside form 5 for molding the circumferential wall is mounted on leveling concrete 4 to bear. An inside form 6 for molding the circumferential wall is separated from the upper surface of the leveling concrete 4 to bear, and a concrete outlet 9 connected to a void D between both inside and outside forms is formed in the lower end of the inside form 6. A wall concrete C is cast in the void D between both inside and outside forms 5 and 6, a floor concrete C is simultaneously or continuously cast on the leveling concrete 4, and both concretes C and C are integrated into a unit without placing joints.
