Title:
FIRE-RESISTING SOUND INSULATING FLOOR
Document Type and Number:
Japanese Patent JP2002173995
Kind Code:
A
Abstract:

To provide a fire-resisting sound insulating floor having both excellent fire-resisting performance and sound-insulating performance and being thin and lightweight enough for easy handleability including constructibility.

The fire-resisting sound insulating floor comprises a deck-plate concrete floor constructed of a deck plate and concrete and laminated on its deck-plate side with a fire-resisting sound insulator formed of at least one layer of thermally-expanding fire-resisting sheet. The thermally-expanding fire- resisting sheet is 0.1 to 10 mm thick and has a specific gravity of 1.5 or more and a tensile modulus of elasticity of 0.294 to 49 MPa as measured with a dumbbell-shaped No.2 test piece based on JIS K-6301. A change in thickness of the fire-resisting sheet when a heat quantity of 50 kW/m2 is applied thereto for 30 minutes (thickness after heat application/thickness before heat application) is 1.1 to 100 times. The fire-resisting sound insulator is a lamination consisting of at least one layer of thermally-expanding fire-resisting sheet and at least one layer of face material formed of non or quasi-noncombustible material.
