Document Type and Number:
Japanese Patent JP2023175573
Kind Code:
A
Abstract:
To provide a dry double floor structure, a floor panel, and a supporting leg capable of improving sound insulation performance.SOLUTION: On the back centers of conifer structural plywood 8, 15, a reinforcement band plate 10, 17 extending in a direction roughly orthogonal to a fiber direction Z in which a grain extends and a connection band plate 14, 19 extending along the back side edge of the conifer structural plywood are provided. The back side edge of the other of adjacent pieces of conifer structural plywood is mounted on the connection band plate of one of the adjacent pieces of conifer structural plywood and connected. Damping materials 9, 13, 16, and 18 are held between the conifer structural plywood and the reinforcement band plate and between the conifer structural plywood and the connection band plate. In the conifer structural plywood 8 supported and fixed along a wall 2 of a structural skeleton among the laid pieces of conifer structural plywood, a damping material fixing band plate 12 is fixed holding a damping material 11 for extension roughly in parallel to the fiber direction Z in which the gain extends in an extra space of the reinforcement band plate and the connection band plate. A supporting leg 4, 5 is provided with a damping material in the top surface, and supports the conifer structural plywood via the damping material of the top surface.SELECTED DRAWING: Figure 1
