▎ 摘　　要

NOVELTY - Interfloor noise prevention construction method of an house comprises constructing a buffer and anti-vibration structure (S10) on the upper surface of the concrete slab to minimize noise generation from the upper floor and to minimize transmission to the lower floor, where buffer and anti-vibration structure includes adiabatic sound absorbing plate made up of silica aerogel and polymer binder, a first noise and vibration blocking plate for blocking and absorbing vibration of sound wave energy, a lightweight foamed concrete layer for sound insulation and heat insulation, a second noise and vibration blocking plate for blocking and absorbing vibration of sound wave energy, a first floor buffer plate formed on the upper surface in any one shape among flat, corrugated, and embossed structures, and a mortar layer in which hot water pipes for heating are installed. The mortar layer contains silicon carbide, carbon-based powder containing nanotubes or graphene. USE - The interfloor noise prevention construction is useful for preventing noise generated in the upper floor from being transmitted to the lower floor through the concrete slab. ADVANTAGE - The method: reduces weight of concrete layer; and blocks noise i.e. light impact sound and heavy impact sound. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram for illustrating method for interfloor noise prevention construction (Drawing includes non-English language text).
