The present invention relates to an inter-story noise prevention structure and a construction method thereof. More specifically, the inter-story noise prevention structure is formed by sequentially stacking a first foam layer, a PU foam layer, a first mixture layer filled with inorganic materials in a lattice-like PU foam body, a second foam body, and a second mixture layer made of a PVC plate, pipes, and scoria mortar between a concrete slab and a flooring material and installing a sponge layer on the wall. Accordingly, the present invention can use the second mixture layer and the second foam layer, and the first mixture layer, then the PU foam layer to reduce the inter-story noises due to the impact applied on a floor. Then, the present invention uses the first foam layer to get rid of the remaining noises. Accordingly, the present invention can reduce and get rid of the inter-story noises and vibration in four phases to ensure excellent noise prevention performance while also removing the horizontal waves of the vibration by using the sponge layer installed on the wall. |
