The present invention relates to an interlayer noise prevention floor material. The floor material can be used to prevent the shock and noise occurring in the upper floor of a multistory building from being transmitted to the lower floor. The interlayer noise prevention floor material according to the present invention includes: a coupling piece (11) which has a narrow width and has an extended shape to protrude from the center of one of the surfaces in the length direction; a plate member (10) which has a coupling groove (12) which is formed to be concave in the length direction to be coupled to the coupling piece from the center of the other surface; multiple shock absorbing members (21) which have the shape of a plate with the same width and length to attach the upper surface to the lower surface of the plate member, are made of an elastic material, and protrude in the length direction from the lower surface to be spaced apart from each other at a predetermined gap; and a shock absorbing member (20) including multiple storage members arranged between the shock absorbing protrusions. |
