Title:
FLOOR-CEILING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2006/030599
Kind Code:
A1
Abstract:
The small beams (13) of a floor structure (10) and the beams (21) of a ceiling structure (20) are disposed so that they are orthogonal to each other. Therefore, the direction of low bending rigidity (the weak axis direction) of the floor structure (10) is orthogonal to the direction of low bending rigidity (the weak axis direction) of the ceiling structure (20). That is, the direction of low bending rigidity of the floor structure (10) coincides with the direction of high bending rigidity of the ceiling structure (20). This reduces heavy floor impulsive sound in which the airborne component is predominant.
