HIGHLY SOUND INSULATING FLOOR OF BUILDING AND BUILDING HAVING HIGHLY SOUND INSULATING FLOOR

摘要

PROBLEM TO BE SOLVED: To prevent the transmission of vibration of a floorboard to a floor beam, to reduce the vibrating area, and to reduce heavy floor impulsive sound by laying a floorboard material by placing the floorboard without being fixed to a corbel fixed to a side surface of the floor beam. ;SOLUTION: In a steel frame or ligneous building, a corbel 4 is fixed to a side surface of a floor beam 1 composed of a steel frame material or wood, a floorboard 2 composed of a lightweight concrete plate and a wooden plate is placed, and upper surfaces of the floor beam 1 and the floorboard 2 are formed in the same height to lay a floorboard material 3 composed of plywood. In this case, the floorboard 2 is put in a state of being still placed on the corbel 4 without being fixed to the corbel 4. The floorboard material 3 is fixed to the floor beam 1 and the floorboard 2 by a machine screw and a nain, and is not fixed to the floorboard 2 to the possible minimum level. Thus, the floor beam 1 and the floorboard 2 are not integrated in strength to prevent the transmission of vibration of the floorboard 2 to the floor beam 1 to reduce the vibrating area to reduce heavy floor impulsive sound so as to constitute an inexpensive highly sound insulating floor.;COPYRIGHT: (C)2001,JPO
