Module Plate for Sound Isolation and Vibration Damping between Floors of Building and Wet Type Double Floor Structure Using It

摘要

The present invention relates to a damping insulation module plate that is constructed on a concrete slab and effectively absorbs a floor impact sound in an on-floor floor structure of a multi-story building, and a wet double floor structure using the same.;In the vibration damping insulation module plate, a plurality of lattice ribs 71 having a predetermined height are formed on the upper surface, and a plurality of protrusions 75 protruding in the vertical direction on the lower surface are formed at regular intervals, and have a rectangular bottom support plate having viscoelastic damping characteristics. 70 and; A dustproof rubber mount 65 having an upper portion inserted into the protrusion 75 and a lower portion positioned on an upper surface of the concrete slab 50 to support the bottom support plate 70; Located in the lower surface of the bottom support plate 70 is characterized in that it comprises a heat insulating material 60 is formed in a hole that is a dustproof rubber mount 65 is inserted into a smaller than the dustproof rubber mount (65).;Therefore, the vibration of the floor itself is first attenuated in the viscoelastic vibration damping layer bound to the vibration damping insulation module plate, and the vibration damping rubber mount applied to the lower support point reduces the vibration transmitted from the ondol layer to the slab secondly. Compared with the double floor structure using only elastic material, the floor impact sound reduction performance is more excellent.;Insulation, Noise between floors, Anti-vibration rubber mount, Visco-elastic damping, Rib, Ondol layer, Floating floor
