Floor sound-absorbing structure and the construction method for preventing interlayer noise
The present invention relates to a sound insulation structure for preventing inter-floor noise and a construction method thereof which use an elastic body of a synthetic resin to effectively reduce a floor impact sound. The sound insulation structure for preventing inter-floor noise comprises: a slab base layer; a sound insulation layer wherein ground ethylene-vinyl acetate copolymer (EVA) and polyethylene terephthalate (PET) are mixed at a prescribed mixing ratio and stacked on an upper surface of the base layer; an infiltration prevention layer disposed on an upper surface of the sound insulation layer and made of a waterproof sheet material which prevents infiltration of water and a foreign substance; a mesh layer of a net structure form stacked on an upper surface of the infiltration prevention layer; and a mortar layer finished and deposited on an upper surface of the mesh layer.
본 발명은 바닥 충격음을 효과적으로 감쇠시킬 수 있도록 합성수지 탄성체를 이용한 층간소음 방지를 위한 바닥 차음구조 및 그 시공방법에 관한 것으로서, 슬래브 기초층; 상기 기초층 상면에 분쇄된 EVA(ethylene-vinyl acetate copolymer) 및 PET(polyethylene terephthalate)가 일정 비율로 혼합되어 적층된 차음층; 상기 차음층의 상면에 마련되어 수분 및 이물질의 침투를 방지하는 방수시트 재질의 침투방지층; 상기 침투방지층 상면에 적층되는 그물 구조 형태의 메쉬층; 및 상기 메쉬층 상면에 마감 타설되는 몰탈층;을 포함하는 것을 기술적 요지로 한다.
