PURPOSE: A double flooring structure is provided to control the vibration of a top panel due to a load, to enhance the strength of a double flooring structure, and to improve the deflection of the top panel by fastening the edges of multiple top panels. CONSTITUTION: A double flooring structure(100) comprises multiple top panels(110), multiple bottom supporting members(130), a supporting part(170), and a vibration proof member(150). The multiple top panels have a bet part(111) in the end. The multiple bottom supporting members support the multiple top panels from the bottom, and have an insertion fixing part(131) which is formed with a fitting groove(131a) for fitting the bent part. The supporting part is installed at the connection part of the bottom supporting members, and supports the edge of the top panel. The vibration proof member is installed at the connection part of the bottom supporting members, is arranged between the bottom supporting member and the supporting part, and reduces the vibration which is delivered through the top panel. |
