본 고안은 층간소음 및 충격흡수용 차음재에 관한 것으로서, 아파트나 빌라 등 다 층으로 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, the purpose of installing a shock-absorbing sound absorbing material between the slab and floor of a multi-storey building, such as apartments and villas to reduce the impact between the floor and the noise.

현재, 법적으로 중량충격음 50dB 이하, 경량충격음 58dB 이하를 만족시키는 완충구조는 많이 알려져 있으나, 비용에 비해 큰 차음성능을 나타내고 있지 않다. 특히, 반건식 타입의 완충구조는 차음성능이 훌륭한 것으로 보고되고 있으나 단가가 매우 높고, 습식 타입의 완충구조는 단가가 저렴한 편이나 차음성능은 상대적으로 뒤떨어지는 경향을 보인다. 따라서, 더욱 향상된 차음구조를 보다 더 저렴한 구조로 구현시킬 필요성이 대두되었다.Currently, many shock absorbing structures satisfying the weight impact sound of 50 dB or less and the light impact sound of 58 dB or less are known, but do not show a large sound insulation performance for the cost. In particular, the semi-dry type buffer structure is reported to have excellent sound insulation performance, but the unit price is very high, and the wet type buffer structure has a low unit price, but the sound insulation performance tends to be relatively inferior. Therefore, there is a need to implement a more improved sound insulation structure with a cheaper structure.

본 고안은 전술한 문제점을 해결하기 위해 안출된 것으로, 건물에서 발생되는 층간소음 저감량을 더욱 향상시키기 위해, 기포콘크리트(30)와 콘크리트 슬라브(10) 사이에 시공할 수 있는 적절한 층간완충재(20)를 구현함에 그 목적이 있다. 특히 중량충격음 차단효과를 크게 향상시키면서도 동시에 제품의 두께를 최소로 줄이는데 효율적인 층간완충재의 구조를 제시하고자 한다.The present invention is devised to solve the above problems, in order to further improve the amount of inter-layer noise generated in the building, an appropriate interlayer buffer material 20 that can be installed between the foam concrete 30 and the concrete slab 10 The purpose is to implement In particular, the present invention proposes a structure of an interlayer cushioning material, which is effective in significantly reducing the weight impact sound effect and at the same time reducing the thickness of the product to the minimum.

수많은 시편제작과 테스트를 통해 얻어진 결과, 기존보다 제품의 두께가 줄어들면서도 소음 진동 흡수성능을 크게 향상시킨 본 층간완충재(20) 고안의 구성은 다음과 같다.As a result of a number of specimens produced and tested, the composition of the present interlayer buffer 20, which greatly improves the noise and vibration absorption performance while reducing the thickness of the product, is as follows.

먼저, 평판구조의 PE보드(200)가 맨 하부에 위치한다. 이 PE보드(200)는 폴리에틸렌 발포폼으로 이루어진 판상형태의 보드로서, 상부의 공기캡보드(201)를 거칠은 슬라브 바닥으로부터 보호하는 역할 및 1kHz 대의 소음진동을 흡수하는 역할을 한다. 그리고 이 위에 공기캡보드(201)를 적층하는데, 돌출된 공기캡(201a)이 위쪽을 향하도록 배열시킨다. 이 공기캡보드(201)는 폴리에틸렌 필름에 열성형을 통해 공기를 주입하여 공기방울이 들어가 있는 공기캡(201a)이 판상위에 성형된 완충재이다. 공기캡보드(201)의 공기캡(201a)을 상부로 향하도록 하는 것은 공기방울이 들어가 있는 부위들을 거칠고 돌출부위가 많은 슬라브 바닥으로부터 보호하기 위함이다. 또한, 이 공기캡(201a)들은 층간에 전달되는 250Hz 이하의 소음 진동을 흡수하는데 효과적인 역할을 한다. 그리고 이 공기캡보드(201) 상부에 메쉬보드(202)를 적층시킨다. 메쉬보드(202)는 그물형태로 이루어져 아래위로 통하는 구멍이 격자모양으로 뚫려져 있는 판상형태의 보드이다. 이 메쉬보드(202)는 EPP, EPS, EVA, PE, PU 등의 탄성을 가진 재질로 구현한다. 또한 이 메쉬보드(202)는 경량충격음 및 중량충격음을 흡수하는 역할을 하는데 주로 500Hz의 소음 진동을 흡수한다.First, the PE board 200 of the flat structure is located at the bottom. The PE board 200 is a plate-shaped board made of polyethylene foam, and serves to protect the upper air cap board 201 from the rough slab bottom and to absorb noise vibration in the 1kHz band. And the air cap board 201 is stacked thereon, the protruding air cap 201a is arranged to face upward. The air cap board 201 is a cushioning material in which air cap 201a containing air bubbles is formed on a plate by injecting air into a polyethylene film through thermoforming. The air cap 201a of the air cap board 201 is directed upward to protect the parts containing the air bubbles from the rough and protruding slab bottoms. In addition, these air caps 201a play an effective role in absorbing noise vibrations of 250 Hz or less transmitted between layers. The mesh board 202 is stacked on the air cap board 201. The mesh board 202 is formed in a net shape and is a board in a plate shape in which a hole passing up and down is drilled in a grid shape. The mesh board 202 is implemented with a material having elasticity, such as EPP, EPS, EVA, PE, PU. In addition, the mesh board 202 serves to absorb light impact sound and heavy impact sound mainly absorbs 500Hz noise vibration.

메쉬보드(202) 상부에 다시 공기캡보드(201)를 적층시킨다. 즉 메쉬보드(202) 상부와 하부에 공기캡보드(201)가 위치한 형태가 된다. 상부에 적층된 공기캡보드(201)는 하부에 적층된 공기캡보드(201)가 흡수하지 못한 250Hz 미만의 잔여 소음 진동을 흡수한다. 그리고 이 공기캡보드(201) 상부에 다시 PE보드(200)를 적층시킨다. 최상위에 적층된 PE보드(200)는 상부의 공기캡보드(201)를 보호하는 역할 및 1kHz대의 소음 진동을 추가적으로 흡수하는 역할을 한다. 결과적으로 메쉬보드(202)를 중심으로 아래위가 서로 대칭적인 구조를 가지게 되는데, 각각의 보드의 두께 및 재질은 서로 상이할 수 있다.The air cap board 201 is stacked again on the mesh board 202. That is, the air cap board 201 is positioned above and below the mesh board 202. The air cap board 201 stacked on the top absorbs residual noise vibration of less than 250 Hz that the air cap board 201 stacked on the bottom does not absorb. Then, the PE board 200 is stacked again on the air cap board 201. The PE board 200 stacked on the top serves to protect the upper air cap board 201 and to further absorb noise vibration in the 1kHz band. As a result, the upper and lower sides of the mesh board 202 are symmetrical with each other, and the thickness and the material of each board may be different from each other.

위에 서술한 다층구조의 층간완충재(20)를 구현하여 시공하면, 각각의 재질이 가지고 있는 주파수 저감 성능이 합산된다. 즉, PE보드에서는 1kHz 부근의 소음 진동을 흡수하고, 메쉬보드는 500Hz 부근의 소음진동을 흡수하며, 공기캡보드는 250Hz 이하의 소음 진동을 흡수하는 역할을 한다. 물론 그 밖의 주파수영역에서도 소음 진동을 흡수하나 위에 설명한 주파수대에서 가장 효과가 크다. 본 고안은 이러한 고유한 주파수 저감성능의 합산효과로 인하여 경량충격음 및 중량충격음 저감효과가 크게 향상된 결과를 나타낸다.Implementing and constructing the above-described layered buffer member 20 of the multilayer structure, the frequency reduction performance of each material is added up. That is, the PE board absorbs noise vibrations around 1 kHz, the mesh board absorbs noise vibrations around 500 Hz, and the air cap board absorbs noise vibrations below 250 Hz. Of course, other frequencies also absorb noise and vibration, but are most effective in the frequency bands described above. The present invention shows a result of greatly improving the light impact sound and the heavy impact sound reduction effect due to the combined effect of the inherent frequency reduction performance.
