| 摘要 |
The present invention relates to an access floor structure capable of reducing vibration. The double-layered floor structure includes a plurality of upper panels; a plurality of lower base members supporting the upper panels from the bottom; a damper-type vibration-proof member installed below the lower base members and having a resilient bending portion which is resiliently bent when a load is transmitted from the upper panel, thereby dispersing the energy and thus damping the vibration transferred from the upper panel; and a support part installed to a connecting portion of the lower base members to support the vibration-proof member from the bottom. The damper-type vibration-proof member has an upper joint portion formed in a plate shape and joined to the lower base member, a lower joint portion positioned below the upper joint portion, formed in a plate shape and joined to the top surface of the support part, and a resilient bent portion connecting the upper and lower joint portions and having a width narrower than those of the upper and lower joint portions. |
