Description

가설용 방음 벽체{sound-proof block wall for construction}Sound-proof block wall for construction

본 발명은 건설공사장을 비롯하여 도로주변과 같이 소음발생이 많은 지역에 설치되는 가설용 방음벽체에 관한 것이다.The present invention relates to a temporary soundproofing wall installed in a noise-prone area, such as a road around the construction site.

본 발명의 가설용 방음 벽체는 방음 벽체와 방음 벽체가 서로 연결되는 양측 연결면에 이중요철 구조로 된 결합부를 형성하여 방음 벽체의 조립성을 향상시키고 방음 벽체의 내면측에 내부에 흡음공간이 형성된 산형돌조를 다중으로 형성하고 산형돌조와 산형돌조 사이에 " Ｖ " 형 단면으로 된 흡음유도홈을 형성하고 흡음유도홈 바닥에 일정간격으로 통공을 형성시킨 흡음유도판을 부착함으로써 발음체에서 발산되어 흡음유도판에 당도하는 음파를 산형돌조가 신속히 분산시켜 흡음유도홈으로 유도하고 통공을 통해 산형돌조 내부공간으로 흡수하여 산형돌조 내부에서 소음시키도록 함으로서 방음작용이 신속하고 양호한 효과를 내게 한 것이다.Hypothetical soundproof wall of the present invention to form a coupling portion of the double concave-convex structure on both sides of the soundproof wall and the soundproof wall connected to each other to improve the assemblability of the soundproof wall and the sound-absorbing space is formed on the inner surface side of the soundproof wall Sound absorption is emitted from the sounding body by forming a plurality of ridges, and forming a sound absorbing guide groove having a "Ｖ" -shaped cross section between the ridges and the ridges, and attaching a sound absorbing guide plate having a hole formed at a predetermined interval on the bottom of the sound absorbing groove. The sound waves arriving on the guide plate are quickly dispersed to the sound absorbing induction grooves and absorbed into the internal spaces of the mountain stones through the through holes to make noise inside the mountain stones.

종래의 가설용 방음벽은 벽체 내면에 흡음판을 부착하고 흡음판이 외부로 이완되지 않게 구멍이 형성된 가림판을 부착하여 가림에 천공한 구멍을 통해 발음체 에서 전달된 음파를 흡착하도록 하고 있으나 발음체에서 발산되어 방음 벽체에 당도한 음파는 방음 벽체 표면에 닿으면서 상당량이 반사하여 일부만 흡수되므로 방음 효과가 낮을 수밖에 없는 결점이 있었고, 방음 벽체와 방음 벽체가 연결되는 곳에 단순한 요철홈이 형성되어 결합되므로 결합력이 낮고 이완이 발생하여 조립이 견고하지 못한 불편이 있었다.Conventional soundproof walls are designed to attach sound absorbing plates to the inner surface of the walls and to attach sound shielding plates with holes to prevent the sound absorbing plates from relaxing to the outside, so that sound waves transmitted from the sounding bodies are absorbed through the holes drilled in the shielding. The sound waves arriving on the wall had a drawback that the soundproof effect was low because only a part of the sound waves were reflected while absorbing the surface of the soundproof wall, and a simple uneven groove was formed where the soundproof wall and the soundproof wall were connected to each other, so that the coupling force was low and relaxed. This occurred, there was an inconvenience that the assembly is not solid.

본 발명은 위와 같은 종래의 결점을 해소시키기 위하여 개발된 것이다.The present invention has been developed to solve the above conventional drawbacks.

본 발명은 가설용 방음 벽체와 방음 벽체가 연결되는 연결면에 이중요철구조로 된 결합부를 형성하고 방음 벽체 내측면에 내부에 흡음공간이 형성된 산형돌조를 다중으로 형성하고 산형돌조와 산형돌조 사이에 단면이 " Ｖ " 형으로 되는 흡음유도홈을 형성하여 흡음유도홈 바닥에 일정간격으로 통공을 형성시킨 흡음유도판을 부착함으로서 발음체에서 발산되어 흡음유도판에 당도하는 음파를 산형돌조가 신속히 분산시켜 흡음유도홈으로 유도하고 흡음유도홈에 형성된 통공을 통해 산형돌조 내부공간으로 흡수하여 소음시킬 수 있게 구성하므로서 저렴한 비용으로 효율이 높은 가설용 방음 벽체를 구성할 수 있게 한 것이다.The present invention forms a coupling part of the double concave-convex structure on the connection surface connecting the temporary soundproof wall and the soundproof wall, and multiplely formed the ridges formed with the sound-absorbing space in the inner surface of the soundproof wall and between the ridges and the ridges By forming a sound absorbing induction groove having a cross-section "형" shape, attaching the sound absorbing induction plate having a through hole at a predetermined interval on the bottom of the sound absorbing induction groove so that the mountain wave quickly disperses sound waves emitted from the sounding body and reaches the sound absorbing induction plate. Induced into the sound-absorbing induction groove and through the through-hole formed in the sound-absorbing induction groove to be absorbed into the interior space of the ridge to make a noise, it is possible to construct a high-efficiency soundproof wall for low cost.

이와 같이 된 본 발명은 가설용 방음벽 본체(1) 내면(1c)측에 내부에 흡음공간이 형성된 산형돌조가 다중으로 형성하고 산형돌조(2a)와 산형돌조(2b)사이에 단면이 " Ｖ "형으로 되는 흡음유도홈(3)을 형성시켜서 흡음유도홈 바닥(3a)을 따라 일정간격으로 통공(3b)을 형성한 흡음유도판(2)을 부착했기 때문에 발음체에서 발산되어 방음 벽체로 전달되는 음파가 흡음유도판(2)에 당도하면 산형돌조에 의하여 신속하게 분산되면서 반사없이 흡음유도홈(3)으로 유연하게 유입되고 흡음유도홈 바닥(3a)에 형성된 통공(3b)을 통해 산형돌조의 내부흡음공간으로 유입되어 소진되므로 흡음작용이 신속하게 그리고 허실없이 이루어져 별도의 흡음재가 없어도 방음 효과가 양호하게 되는 이점이 있다.According to the present invention as described above, a plurality of ridges having a sound absorbing space therein are formed on the inner surface 1c side of the temporary soundproof wall main body 1, and a cross section is formed between the ridges 2a and the ridges 2b. Since the sound-absorbing induction groove (3) is formed to form a sound-absorbing induction plate (2) formed through the bottom of the sound-absorbing induction groove (3a) at a predetermined interval to attach the sound absorbing guide plate (2) is emitted from the sounding body and transmitted to the soundproof wall When the sound wave reaches the sound absorbing induction plate (2), it is rapidly dispersed by the ridge, and is smoothly introduced into the sound absorbing induction groove (3) without reflection, and through the through hole (3b) formed in the sound absorbing induction groove bottom (3a) Since the sound absorbing effect is quickly and without loss because it is introduced into the internal sound absorbing space, there is an advantage that the soundproofing effect is good even without a separate sound absorbing material.

그리고 본 발명은 흡음유도판(2) 내면에 통기성 흡음판(4)을 개입할 경우 산형돌조와 산형돌조의 내부에 형성된 흡음공간이 서로 차단되고 흡음공간으로 유입된 음파이동이 방지되므로 소음작용이 더욱 양호하게 이루어져 방음효과를 더욱더 높일 수 있기 때문에 보다 높은 방음을 요구할 때 선택적으로 실시할 수 있게 되는 이점이 있다.In the present invention, when the sound-absorbing induction plate (2) through the air-absorbing sound absorbing plate 4, the sound absorbing space formed in the interior of the ridges and the ridges is blocked from each other, and the sound pipes are prevented from entering the sound-absorbing spaces, so that the noise action is more. It is advantageous to be able to selectively perform when a higher sound insulation because it can be made better sound insulation effect.
