PROBLEM TO BE SOLVED: To prevent a floor impact noise that occurs in one of the two living spaces formed adjacent to each other on a floor slab from propagating into the other living space. SOLUTION: A building comprises the floor slab formed of a reinforcement concrete, two living spaces formed adjacent to each other on the floor slab, a floor plate supported on the floor slab with a supporter interposed therebetween in each living space, and a sound insulator removably attached to the floor slab at the boundary portion of the living spaces between the floor slab and the floor plate. The sound insulator comprises a band-like flat concrete extending in the extending direction of the boundary line between the living spaces. COPYRIGHT: (C)2009,JPO&INPIT
