PROBLEM TO BE SOLVED: To further suppress transmission of noise and vibration on a double floor.SOLUTION: A double floor comprises: supporting leg members 10A, 10B, which are disposed on a floor slab 2; a floor substrate material 101, which is supported on the supporting leg members 10A, 10B; intermediate laying materials 102A, 102B, which are laid on the floor substrate material 101; and a floor finishing material 103, which is laid on the intermediate laying materials 102A, 102B and forms the floor surface. The supporting leg members 10A, 10B connect multiple supporting legs 11, 21 and supporting legs 11, 21, which are erected on the floor slab 2, with each other and has connecting members 12, 22, which support the floor substrate material 101. The intermediate laying material 102A is made of a material with higher rigidity and specific gravity than the floor substrate material 101, the intermediate laying material 102B and the floor finishing material 103.SELECTED DRAWING: Figure 2 |
