본 발명은 층간소음 및 충격흡수용 차음재에 관한 것으로서, 아파트나 빌라 등 다층으로 이루어진 건물의 슬라브와 바닥재 사이에 충격흡수용 차음재를 설치하여 층간 충격 및 소음을 저하시키는데 그 목적이 있다.The present invention relates to a sound absorbing material for noise and impact absorption between floors, an object of reducing the impact and noise between floors by installing a sound absorbing sound absorbing material between the slab and the floor of a multi-storey building, such as apartments and villas.

현재, 법적으로 중량충격음 50dB 이하, 경량충격음 58dB 이하를 만족시키도록 법에서 규정하고 있다. 그러나 중량충격음 50dB를 만족시키는 것은 매우 어려운 것으로 알려져 있으며, 특히 작은 방의 경우에는 방바닥의 공진주파수가 저 주파 대역에 존재하기 때문에 중량충격음에 있어서는 오히려 소음이 증폭되는 현상이 일어나는 것으로 보고되어 있다.At present, the law stipulates to satisfy 50dB or less of heavy impact sound and 58dB or less of light impact sound. However, it is known that it is very difficult to satisfy the 50 dB of heavy shock sound, and especially in a small room, it is reported that the noise is amplified in the heavy shock sound because the resonance frequency of the floor exists in the low frequency band.

이러한 법적, 현실적 문제들을 해결하기 위해 많은 노력들이 있었는데, 지금까지 개발된 층간차음재들의 공통된 특징을 두 가지로 요약하자면 다음과 같다.There have been many efforts to solve these legal and practical problems. The common features of the sound insulation materials developed so far can be summarized as follows.

첫째, 층간차음재들은 주로 탄성물질로 이루어져 있다. 예를 들자면, EPS(Expendable Polystyrene), PE(polyester), EPP(Expanded Polypropylene), EVA(ethylene-vinylacetate), PU(polyurethane), PET(polyethylene terephthalate) 등의 합성수지와 고무계통 재질 등 상상할 수 있는 모든 종류의 탄성물질을 이용하여 개발되어져 왔다. 그러나 특정 탄성물질을 이용할 때 충분한 차음성능이 나온다는 물질은 현재까지 알려져 있지 않다.First, interlayer insulation materials are mainly composed of elastic materials. For example, all imaginable resins such as EPS (Expendable Polystyrene), PE (Polyester), EPP (Expanded Polypropylene), EVA (ethylene-vinylacetate), PU (polyurethane), PET (polyethylene terephthalate), etc. It has been developed using a variety of elastic materials. However, it is not known until now that a sufficient sound insulation performance is obtained when using a specific elastic material.

둘째, 층간차음재들은 기본적으로 판상형태로 만들어지는데, 몇몇 경우에 있어서는 판의 하부 또는 상부에 돌출형 돌기, 또는 볼록하거나 오목한 문양들을 성형하는 방식을 취해왔다. 그러나 그러한 발명들이 중량충격음을 충분히 차단하지는 못하는 것으로 업계에 알려져 있다. 따라서, 층간소음을 보다 더 효율적으로 차단하며 중량충격음저감 효과를 크게 향상시킬 수 있는 차음재의 재질 또는 구조에 대한 정량적인 연구와 개발이 요구되었다.Secondly, interlayer insulation materials are basically made in the form of plates, and in some cases they have been employed to form protrusions or convex or concave patterns on the bottom or top of the plate. However, it is known in the art that such inventions do not sufficiently block heavy impact sound. Therefore, quantitative research and development of the material or structure of the sound insulation material which can block the noise between layers more efficiently and greatly improve the effect of reducing the weight impact sound is required.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로, 건물에서 발생되는 층간소음을 법적 기준 이하로 만족시키기 위해, 마감 몰탈층(400)과 바닥 콘크리트 슬라브(100) 사이에 시공할 수 있는 적절한 층간차음재(200)를 구현함에 그 목적이 있다. 특히 중량충격음 차단효과를 크게 향상시키기 위한, 층간차음재의 구조에 대한 규격을 명확히 제시하고자 한다.The present invention has been made to solve the above-described problems, to satisfy the interlayer noise generated in the building below the legal standards, suitable interlayer that can be installed between the finishing mortar layer 400 and the floor concrete slab 100 The purpose is to implement the sound insulation material 200. In particular, the specification of the structure of the interlayer sound insulation material is clearly proposed to greatly improve the effect of heavy shock sound.

수많은 시편제작과 테스트를 통해 얻어진 데이터를 분석해보았을 때, 지금까지 나온 층간차음재들 보다 크게 향상된 소음차단 성능을 달성하기 위한 본 층간차음재 발명의 구성은 다음과 같다.수많은 시편제작과 테스트를 통해 얻어진 데이터를 분석해보았을 때, 지금까지 나온 층간차음재들 보다 크게 향상된 소음차단 성능을 달 성하기 위한 본 층간차음재 발명의 구성은 다음과 같다.After analyzing the data obtained through numerous specimen fabrication and testing, the composition of the invention of the interlayer sound insulation material to achieve the noise blocking performance greatly improved than the interlayer sound insulation materials so far is as follows. In the analysis of the present invention, the construction of the present invention of the interlayer sound insulation material to achieve the noise blocking performance significantly improved than the interlayer sound insulation materials so far is as follows.

직사각형 형태의 상판(201)을 5mm에서 70mm 사이의 두께로 만들고(단, 가로, 세로의 길이는 임의로 한다), 그 하부에 소음 및 충격을 흡수하기 위해 돌기(202)를 임의의 개수로 성형한다. 이 돌기들이 층간에 전달되는 소음과 진동을 흡수하게 되는데, 돌기의 구성이 어떻게 될 때 그 효과가 극대화 되는지에 대해서는 아래에서 설명한다.The rectangular top plate 201 is made to have a thickness of 5 mm to 70 mm (but the width and length are arbitrary), and the protrusions 202 are formed in any number to absorb noise and impact thereunder. . These protrusions absorb the noise and vibration transmitted between layers, and how the structure of the protrusion is maximized will be described below.

돌기(202)는 원뿔, 원통, 육면체를 포함하여 임의의 형태를 가지는 입체로 성형할 수 있다.(모양은 중요하지 않다.) 단, 돌기(203)의 높이, 즉 돌기의 하단부부터 상판(201)의 하부면까지의 수직 높이가 10mm 이상인 특성을 가진다. 즉, 다음의 수식으로 표현된다.The projection 202 may be formed into a three-dimensional shape having any shape, including a cone, a cylinder, and a cube. (The shape is not important.) However, the height of the projection 203, that is, the upper plate 201 from the lower end of the projection. Vertical height to the lower surface of the) is 10mm or more. That is, it is expressed by the following formula.

H ≥ 10mm (H : 돌기의 하단부부터 상판(201)의 하부면까지의 수직 높이)H ≥ 10mm (H: vertical height from the lower end of the projection to the lower surface of the upper plate 201)

접지면(203)은 돌기의 하부면으로서, 층간차음재가 시공되었을 때에 돌기(202)가 바닥에 접하게 되는 전체면을 지칭한다. 접지면(203)은 임의의 3차원 자유 곡면으로 성형할 수 있다. 본 발명이 제시하는 층간차음재는 아래의 수학식1을 만족해야 한다.The ground surface 203 is a lower surface of the projection, and refers to the entire surface where the projection 202 comes into contact with the floor when the interlayer sound insulating material is constructed. The ground plane 203 can be formed into any three-dimensional free curved surface. The interlayer sound insulating material proposed by the present invention should satisfy the following Equation 1.

R ≤ 0.25R ≤ 0.25

여기서, R ≡ ∑Sb / Su Where R ≡ ∑S b / S u

Su : 상판(201)의 윗면넓이S u : Top width of the upper plate 201

Sb : 실 시공시 바닥에 닿게 되는 접지면(203)의 넓이S b : the width of the ground surface 203 that comes in contact with the floor during construction

돌기(202)를 배열하는 방법은 다음과 같다. 상판(201)의 하부에 돌기(202)가 N개 가 존재한다고 가정하자. 또한, 각각의 돌기의 접지면(203)의 무게중심을 나타내는 3차원 위치벡터를 Pk (k = 1,2,…,N)라 정의하자. 이때, Lmin의 조건과 정의는 수학식2와 같다.The method of arranging the protrusions 202 is as follows. Assume that N protrusions 202 exist at the bottom of the upper plate 201. In addition, let us define a three-dimensional position vector representing the center of gravity of the ground plane 203 of each projection as P k (k = 1,2, ..., N). At this time, the condition and definition of L min is the same as Equation 2.

Lmin ≥ 40mmL min ≥ 40mm

Lmin ≡ Min(|Pi - Pj|) (단, i,j = 1,2,…,N, i≠j)L min ≡ Min (| P i -P j |) (where i, j = 1,2,…, N, i ≠ j)

위의 수학식2를 만족하도록 돌기(202)들을 상판(201) 하부에 배열하는 것을 본 발명의 특징으로 한다. 이 조건을 만족시키는 조건 하에서 돌기들을 자유롭게 배치할 수 있다.It is a feature of the present invention to arrange the protrusions 202 below the top plate 201 to satisfy the above equation (2). The protrusions can be freely arranged under conditions that satisfy this condition.

층간차음재(200)는 탄성 재료로 성형하는데, EVA, EPP, PP, PS, EPS, ABS, PU, PET 등을 포함한 합성수지계열과 고무계열 수지를 모두 포함하며, 여러 종류의 재질을 혼합하여 사용할 수 있는 것을 특징으로 한다.(예: 상판은 EVA, 돌기는 EPP, 접지면은 PU 재질로 구현)The interlayer sound insulating material 200 is formed of an elastic material, and includes both synthetic resin and rubber-based resins including EVA, EPP, PP, PS, EPS, ABS, PU, PET, and can be used by mixing various kinds of materials. (E.g. top plate is EVA, projections are EPP, ground plane is made of PU material)

위와 같은 조건을 동시에 만족하는 층간차음재를 성형하면, 바닥 콘크리트 슬라브를 대상으로 소음을 측정했을 때에 비해 중량충격음 저감효과가 9-10dB 이상 대폭 향상된 층간차음재를 구현할 수 있으며, 그 실험결과는 도면1, 도면2에 도시한 그래프와 같다.By forming the interlayer sound insulation material satisfying the above conditions at the same time, it is possible to realize the interlayer sound insulation material with a significantly improved effect of reducing weight impact sound by more than 9-10dB compared to when noise is measured on the floor concrete slabs. Same as the graph shown in FIG.

도면 1은, 동일 재질, 동일 돌기 형태, 그리고 Lmin 의 값은 40mm으로 고정했을 경우에 있어서, H와 R과 E의 상관관계를 나타낸 그래프이다.도면 2는 동일 재질, 동일 돌기 형태, 그리고 H의 값은 10mm으로 고정했을 경우에 있어서, Lmin와 R과 E의 상관관계를 도시한 그래프이다. 도면 1, 도면2에 있어서의 기호의 정의는 수학식 1, 2, 3을 따르며, E는 중량충격음 저감효과를 나타낸다.1 is a graph showing the correlation between H , R, and E when the same material, the same protrusion shape, and the value of L min are fixed at 40 mm. FIG. 2 shows the same material, same protrusion shape, and H. FIG. The value of is a graph showing the correlation between L min , R and E when fixed at 10 mm. The definition of the symbol in FIG. 1, FIG. 2 follows Formula (1), (2), (3), and E shows the effect of reducing the weight impact sound.
