<p>PROBLEM TO BE SOLVED: To solve the problem of requiring for sealably processing an end part of a double floor for securing its performance, the problem of bringing about performance reduction since sealing part of a baseboard and the double floor becomes a sound bridge in sealing processing by conventional baseboard close contact construction, the problem of an aesthetic appearance and durability in the sealing processing by a gum tape, and the problem of workability and a cost increase though the sealing processing by installation of a sealant is a sure method, in a high performance sound insulation double floor incorporated with a Helmholtz type resonance box used for a floor finishing structure such as an RC house.SOLUTION: In the sealing processing of a corresponding part, an elastic body such as sponge and the baseboard with a fin are installed, thereby, being able to easily secure sealability of a degree of being excellent in workability, durability, cost reduction and an aesthetic appearance, hardly becoming the sound bridge, and requiring for securing performance.</p> |
