Claims

[Scope of Claim for Utility Model Registration] (1) In a flooring device consisting of a flooring panel and a plurality of support legs provided at the bottom of the flooring panel, the flooring panel is composed of a flooring panel, vibration damping material, and sound absorbing material. A soundproof and vibration-proof flooring device characterized by having a three-layer structure. (2) The support legs have an upper support part having a collar part for receiving the floor substructure panel and a female thread part to be threaded into the column part, and a male thread part in the upper part to be threaded into the upper support part. A sound-proofing and vibration-proofing flooring device according to claim 1, which is a utility model, and comprises a pillar portion to which a vibration-proofing material is attached directly or indirectly. (3) The sound-proof and vibration-proof underfloor device according to claim 1 or 2 of the utility model claim, characterized in that the vibration-proof material has a two-layer structure in which the lower part is rubber-based and the upper part is inorganic fiber-based. (4) Claims for a utility model characterized in that the vibration isolating material is attached to a receiving member having a support shaft at the top, and the support shaft of the support member is rotatably supported at the bottom of the support. The soundproof and vibration-proof flooring device according to any one of Items 1 to 3.
