도 1은 본 고안에 의한 방음블록의 분리사시도이고, 도 2는 흡음재가 삽입된 상태의 방음블록의 단면도이며, 도 3은 본 고안에 의한 방음블록의 시공상태를 도시한 정면도로서, 본 고안은 콘크리트로 성형되고 전면에 요철(12)이 형성되며 전면에서 내부의 공극(14)으로 흡음공(16)이 관통형성된 블록(10)과, 이 블록(10)의 공극(14)에 삽입설치되는 흡음재(20)로 이루어진 방음블록에 있어서, 상기 흡음재(20)는 일정두께를 갖는 폴리에스테르 부직포층(22)의 전면에 흡음구멍(24)이 무수히 천공된 박막의 폴리스틸렌 비발포 표면층(26)을 적층시켜서 된 것을 특징으로 한다.1 is an exploded perspective view of the soundproof block according to the present invention, Figure 2 is a cross-sectional view of the soundproof block in the sound absorbing material is inserted state, Figure 3 is a front view showing the construction of the soundproof block according to the present invention, The block 10 is formed of concrete and the concave-convex 12 is formed on the front surface, and the sound-absorbing hole 16 penetrates into the air gap 14 from the front surface, and is inserted into the air gap 14 of the block 10. In the soundproof block made of the sound absorbing material 20, the sound absorbing material 20 is a polystyrene non-foamed surface layer 26 of the thin film in which the sound absorbing holes 24 are perforated innumerably on the front surface of the polyester nonwoven fabric layer 22 having a predetermined thickness. It is characterized by being laminated.
도면에 도시한 바와 같이 상기 흡음재(20)는 블록(10)의 공극(14)에 안전히 채워지지 않고 공극(14)의 후부는 빈 공간(S)이 되도록, 바람직하게는 공극(14) 체적의 약 50% 내외가 흡음재(20)로 채워지지 않고 빈공간이 되도록 하는 것이 흡음재를 전부 채웠을 경우보다 흡음효과가 높다는 사실이 실험적으로 발견되었고, 이때 흡음재의 소재도 절반가량 절약할 수 있게 된다.As shown in the figure, the sound absorbing material 20 is not securely filled in the voids 14 of the block 10 and the rear part of the voids 14 is an empty space S, preferably of the volume of the voids 14. It has been found experimentally that about 50% of the sound absorbing material is not filled with the sound absorbing material 20 and becomes empty, and the sound absorbing effect is higher than when the sound absorbing material is completely filled, and the material of the sound absorbing material can also be saved by about half.
상기 흡음재(20)는 폴리에스테르 부직포층(22)과 비발포 폴리스틸렌 표면층(26)을 일정크기로 크게 형성하며, 현장에서 방음블록(10)의 공극(14)칫수에 맞게 커터 등의 절단도구를 사용하여 폭과 길이를 맞추어 절단하여 시공할 수 있으며, 이때, 본 고안의 흡음재(20)는 소재 자체가 인체 특히, 피부와의 접촉이 있더라도 피부질환이나 호흡기 등에 영향을 미치지 않으므로 별도의 보호장구를 착용하지 않아도 되므로 작업성이 우수하다.The sound absorbing material 20 forms a polyester nonwoven fabric layer 22 and a non-foamed polystyrene surface layer 26 to a certain size, and cuts tools such as cutters to fit the air gap 14 of the soundproof block 10 in the field. It can be cut and constructed to match the width and length by using, and at this time, the sound absorbing material 20 of the present invention does not affect the skin disease or respiratory organs, even if the material itself is in contact with the human body, in particular, the skin is a separate protective equipment Excellent workability because there is no need to wear.
또한, 상기 흠음재(20)는 기존의 방음블록에 사용되었던 유리섬유소재가 재사용이 불가능하고 소각이 어려웠던 것에 비해 재활용과 소각처리가 가능하고 소각시 미립자 발생이 없어 한경친화적일 뿐만 아니라, 이의 운반 및 취급시 피부와의 직접접촉을 방지하거나 마스크와 같은 별도의 보호장구없이 취급이 가능하여 작업성이 우수하며, 폴리에스테르 부직포는 인장강도와 상호 결합력이 우수하여 자체의 구조적인 안정성을 가져 내구성이 우수하고, 표면층은 박막의 비발포 폴리스틸렌으로 앞뒤로 흡음구멍이 관통형성되어 있어 소음원으로부터 발생된 소음을 효과적으로 흡수할 수 잇도록 함과 동시에 부직포의 전면에 부착되므로써 외부에서 부직포가 드러나지 않도록 가려줌과 동시에 부직포의 형태안정성을 보완해 주게 된다.In addition, the flaw material 20 is recycled and incinerated, and the glass fiber material used in the existing sound-proof block is not reusable and incinerated is difficult, and there is no generation of fine particles during incineration, which is not only one-friendly, but also transports thereof. And it prevents direct contact with skin when handling or handles without a separate protective device such as mask, so it is excellent in workability. Polyester non-woven fabric has excellent tensile strength and mutual bonding force, which has its own structural stability and durability. The surface layer is a non-foamed polystyrene thin film, and the sound absorbing hole is formed through the front and back to effectively absorb the noise generated from the noise source, and is attached to the front side of the nonwoven fabric to hide the nonwoven fabric from the outside. It will supplement the form stability of nonwoven fabric.
이상 설명한 바와 같이 본 고안은 블록의 내부에 형성된 공극에 흡음구멍이 무수히 천공된 표면층을 갖는 폴리에스테르 부직포로 된 흡음재를 내설하여서 된 것으로, 본 고안에 의하면 흡음재가 환경친화적인 소재로 이루어져 작업성이 우수할 뿐만 아니라 재활용이 가능하고, 종전과 같이 별도의 알루미늄 박판을 씌울 필요도 없어 시공비용을 절감할 수 있고, 자체의 형태안정성이 우수할 뿐만 아니라 표면층에 의해 보강되므로 내구성이 향상되며 부직포층은 표면층에 가려져 있으므로 그 미관도 해치지 않는 효과를 갖는다.As described above, the present invention is made by incorporating a sound absorbing material made of a polyester nonwoven fabric having a surface layer in which the sound absorbing holes are perforated in the pores formed in the interior of the block. According to the present invention, the sound absorbing material is made of an environmentally friendly material. Not only is it excellent, it is recyclable, and there is no need to cover a separate aluminum sheet as in the past, so construction cost can be reduced, its shape stability is excellent and its durability is improved because it is reinforced by the surface layer. Since it is covered by the surface layer, it has an effect of not hurting its aesthetics.
