Title:

DIRECT STICKING METHOD FOR INTERNAL FACING BOARD AND SOUND INSULATING WALL CONSTRUCTION

Document Type and Number:

Japanese Patent JPH1088690

Kind Code:

A

Abstract:

To provide a direct sticking method capable of reducing noises propagating between an internal facing board and a concrete skeleton and promoting sound insulating efficiency in a broad-range area specially from a low frequency band to a high frequency band.

In this direct sticking method and sound insulating wall construction, a sound absorbing material 3 of a glass-wool board with 30mm-40mm in thickness is temporarily fixed to the whole body of a skeleton wall surface 2 with nails, and then, holes 4 are filled with mortar adhesives 5 formed in the shape of a dumpling with an approximately 50mm diameter so that they are projected from the surface of the sound abaorbing material 3. A vibration- proof material 6 of a resin molded board fitted to size of the holes 4 is smoothed with ruler, etc. until it is flush with the suface of the sound absorbing material 3, and it is housed in the holes 4. Then, an internal facing board 8 of a gypsum plasterboard is brought into contact with the smooth surface, and a wood screw 7 passes through a position of the vibration-proof material to fix the internal facing board 8 and vibration-proof material 6 to each other.
