Zusammenfassung: | In accordance with the present invention, disclosed is a floor for reducing noise between floors. The floor includes: a unit SPC floor panel (100); a floor noise reduction structure including a frame part (110) having a floor panel attachment surface (111) and a construction floor attachment surface (112) formed in upper and lower parts respectively, formed in a shape corresponding to the size of the unit SPC floor panel (100), having a plurality of space parts (113) spatially separated by a grid frame (114) in a matrix form and arranged therein, and formed with a first thickness (T1), a damping part (120) formed with a second thickness (T2) smaller than the first thickness (T1) and formed at a height above the floor panel attachment surface (111) to be resonated vertically and laterally, formed as at least one unit in each of the space parts (113), extended from at least one side of the grid frame (114) to damp vibrations and noise transmitted from the floor panel attachment surface (111), and a support part (130) erectly formed at a predetermined height from the construction floor attachment surface (112) to come in surface contact, line contact or point contact with the construction floor; and a sound absorption pad (140) having a thickness of 1 to 3 mm, attached between the unit SPC floor panel (100) and the floor noise reduction structure through an adhesive to damp vibrations and noise transmitted from the unit SPC floor panel (100). Therefore, the unit SPC floor panel (100), the floor noise reduction structure and the sound absorption pad (140) are integrated to effectively damp vibrations and noise transmitted from the SPC floor panel (100) without the need for extra sound absorption construction during floor construction.
본 발명은, 단위 SPC 마루패널(100), 마루패널 부착면(111)과 시공바닥 부착면(112)이 상하로 각각 형성되며, 단위 SPC 마루패널(100)의 크기에 상응하는 형상으로 형성되고, 내측에 다수의 공간부(113)가 격자프레임(114)에 의해 매트릭스 형태로 공간적으로 분리되어 배열되고, 제1두께(T1)로 형성된, 프레임부(110)와, 제1두께(T1)보다 작은 제2두께(T2)로 형성되어 마루패널 부착면(111)으로부터 들뜬 높이로 형성되어 상하좌우로 울리며, 공간부(113)별로 내측에 하나 이상 형성되고, 격자프레임(114)의 각 변 중 적어도 하나 이상으로부터 연장되어 마루패널 부착면(111)으로부터 전달되는 진동 및 소음을 감쇄시키는 감쇄부(120)와, 시공바닥 부착면(112)으로부터 일정높이로 직립 형성되어 시공바닥과 면접촉, 선접촉 또는 점접촉하는 지지부(130)를 포함하는 층간소음 저감 구조체, 및 단위 SPC 마루패널(100)과 층간소음 저감 구조체 사이에 접착제에 의해 각각 부착되어 단위 SPC 마루패널(100)로부터 전달되는 진동 및 소음을 감쇄하는 1mm 내지 3mm 두께의 흡음패드(140)를 포함하여, 단위 SPC 마루패널(100)과 층간소음 저감 구조체와 흡음패드(140)를 일체형으로 형성하여 마루시공시 별도의 흡음공사를 수행하지 않고, SPC 마루패널(100)로부터 전달되는 진동 및 소음을 효과적으로 감쇄하는, 층간소음 저감마루를 개시한다. |
