Title:
FLOOR STRUCTURE FOR PREVENTING NOISE BETWEEN FLOORS HAVING DUAL-FLOATING-FLOOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/107617
Kind Code:
A1
Abstract:
The present invention relates to a floor structure for preventing noise between floors, having a dual-floating-floor structure and, more specifically, to a floor structure for preventing noise between floors, wherein a floor separation plate, which has spacing bodies provided therein at constant intervals, and an upper support plate, which has support means protruding downward to contact the upper surfaces of the spacing bodies, are sequentially stacked. In particular, the prevent invention relates to a floor structure for preventing noise between floors, wherein weight vibration noise transmitted from above is removed by the spacing bodies of rubber material absorbing and offsetting the noise in multiple stages, and minor noise is offset by upper and lower dual air layers between the floor separation plate and spacing balls through the reflection of sound occurring while passing through different media, and thus, while simplifying the structure, noise between floors can be minimized by noise attenuation in multiple stages.
