A sound prevention layer(5) is placed between a slab layer(1) and a finishing mortar layer(3). Sound prevention panels(10) are made by having urethane foam, form polystyrene, a rubber based buffer material, a fiber compressive buffer material, and a light weight concrete having the same size as the buffer material with a shape of excelling in a sound prevention function. The sound prevention panels are placed on the slab layer with the same gap. A vertical buffer material(14) is placed at the part contacted with a wall body(2).
