<p>The present invention relates to a floor supporter for preventing noise through a floor using a vacuum layer. The generation of noise through a floor can be prevented effectively by forming a vacuum cylinder part on a supporting plate, on which a floor structure is put, forming a vacuum layer therein, inserting and coupling the piston head of a supporting leg, and blocking the main propagation path of solid-transmitted sound constituting floor shock sound, particularly, weight shock sound, which is transmitted to a lower floor through the supporting leg, using the vacuum layer formed in the vacuum cylinder. A part in contact with solid, which is inevitably generated when the supporting leg is coupled to the supporting plate, can be minimized. Accordingly, tightened criteria for a floor structure and tightened criteria for the performance of blocking floor shock sound of public housing can be satisfied by dispersing the propagation path of transmitted solid-transmitted sound and reducing the generation of noise through a floor more effectively.</p> |
