Description
본 고안은 도심지 및 주택가에 설치된 고층건물과 인접한 도로내의 소음을 차단하기 위한 터널형 방음시설에 관한 것으로, 특히, 방음판이나 투명판으로 된 천장의 내측면에 망과 흡음재로 형성된 공기층을 다수 형성하므로서, 소음의 반사와 흡음효과를 극대화함은 물론, 설치작업이 용이하고 교체,보수 등의 유지관리가 용이하며, 외관을 향상시킨 공기층을 구비한 방음천장이 설치된 터널형 방음시설에 관한 것이다.The present invention relates to a tunnel-type soundproofing facility for blocking noise in a road adjacent to a high-rise building installed in a city center and a residential area, and in particular, by forming a plurality of air layers formed of a net and sound absorbing material on the inner surface of a ceiling made of soundproof plates or transparent plates. The present invention relates to a tunnel-type soundproofing facility equipped with a soundproof ceiling having an air layer having an improved appearance, as well as maximizing noise reflection and sound absorption effects, as well as easy installation, maintenance, and replacement.
일반적으로 도심지 및 주택가에 시공되어지는 고층건물은, 도로와 인접한 것이 통상적이고 이러한 인접도로에서 발생하는 차량의 소음으로부터 노출되어 있는 것이 보통이다.In general, high-rise buildings constructed in urban areas and residential areas are usually adjacent to roads and are usually exposed from the noise of vehicles generated on these adjacent roads.
이러한 도로 내부의 소음을 차단 또는 흡수하기 위해 각종 차단벽 또는 흡음벽 등을 도로변에 설치하여 도로 내부의 소음이 건물에 직접 영향을 미치는 것을 방지하고 있으나, 이러한 차단벽 또는 흡음벽은 그 설치 높이의 한계성으로 인하여 일정한 층고 이상부터는 도로 내부의 소음으로부터 안전하지 못한 문제점이 있는 것이다.In order to block or absorb the noise inside the road, various barrier walls or sound absorbing walls are installed on the roadside to prevent the noise inside the road from directly affecting the building. Due to the limitation, there is a problem that is not safe from noise inside the road from a certain height above.
따라서, 상기한 바와 같이 고층건물이 밀집한 도심지 또는 주택가에는 터널형 방음시설이 적용되는 것인데, 상기한 터널형 방음시설은 도로의 양측면 및 상부를 완전히 밀폐시켜 도로 내부의 소음이 외부로 새어나가지 못하게 함과 동시에 도로 내부의 소음을 효과적으로 흡수하여 운전자에게 영향을 미치는 주행 소음 또한 감소시키게 되는 것이다.Therefore, as described above, the tunnel-type soundproofing facility is applied to a city center or a residential area where high-rise buildings are concentrated. The tunnel-type soundproofing facility completely seals both sides and the upper part of the road so that the noise inside the road does not leak to the outside. At the same time, it effectively absorbs the noise inside the road, reducing the running noise that affects the driver.
상기한 터널형 방음시설은 도 5의 도시와 같이 통상적으로 도로의 양측에 일정높이의 콘크리트 기초(100)를 타설 양생시키고, 그 상부에 일정 간격의 H-형강(101)(101')을 수직 입설시키며, 도로의 횡단방향으로 대향된 수직 H-형강을 또다른 수평 H-형강을 이용하여 서로 연결한 상태에서, 상기 이격된 수직 H-형강의 사이와, 이격된 수평 H-형강의 사이에는 차음패널 또는 흡음패널(102)(102')을 순차적으로 삽입하여 고정함으로서, 상기 차음패널 또는 흡음패널(102)(102')에 의해 도로 내부에서 발생하는 소음을 효과적으로 차단 또는 흡수하게 되는 것이다.In the tunnel-type soundproofing system, as shown in FIG. 5, a concrete foundation 100 having a certain height is poured on both sides of a road and vertically H-shaped steels 101 and 101 ′ are vertically spaced thereon. In between the spaced vertical H-beams and between the spaced horizontal H-beams, the vertical H-beams opposed in the transverse direction of the road are connected to each other using another horizontal H-beam. By inserting and fixing the sound insulation panels or sound absorbing panels 102 and 102 'sequentially, the sound insulation panels or sound absorbing panels 102 and 102' effectively block or absorb the noise generated inside the roadway.
또한, 터널형 방음시설은 그 터널 내부의 채광을 위해 방음시설의 측면 또는 지붕측에 투명패널(103)을 일정개수 삽입하여 상기 투명패널에 의해 밀폐된 터널 내부의 채광은 물론 자연채광을 이용하여 절전 효과를 갖게 하거나, 방음벽에 설치하는 방음판을 설치하여 터널내부에서 발생하는 소음을 흡수 또는 반사토록 하였다.In addition, the tunnel-type soundproofing facility inserts a certain number of transparent panels 103 into the side or roof side of the soundproofing facility for light in the tunnel, and uses natural light as well as light inside the tunnel sealed by the transparent panel. It has a power saving effect or installs a soundproof board installed on the soundproof wall to absorb or reflect the noise generated inside the tunnel.
그러나 상기와 같은 종래의 터널형 방음시설은, 천장이 투명패널이나 방음벽에 설치되는 것과 동일한 방음판이 설치되어 있으므로, 소음의 반사면적보다 흡음면적이 더 필요한 터널내부의 상황에 적합하지 않아 방음효과가 미약할뿐만아니라, H-형강 사이에 방음판을 삽입하는 구조이기 때문에 구조물과 방음판간의 간섭이 발생하여 설치작업 및 교체, 보수 등의 유지 관리가 매우 어려운 문제점이 있었다.However, in the conventional tunnel type soundproofing facilities as described above, since the same soundproof panels are installed on the transparent panels or soundproof walls, the soundproofing effect is not suitable for the situation in the tunnel where the sound absorbing area is required more than the reflection area of the noise. In addition to being weak, since the sound insulation plate is inserted between the H-beams, interference between the structure and the sound insulation plate occurs, and thus there is a problem in that maintenance work such as installation work, replacement, and maintenance is very difficult.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서,The present invention is devised to solve the above problems,
터널형 방음시설의 천장에 다수의 흡음재와 공기층으로 구성된 흡음장치를 설치하므로서, 소음의 흡음면적을 최대화하고, 소음이 흡음재를 통과하는 횟수를 최대화하여 방음효과를 극대화 함은 물론, 설치 및 교체, 보수 작업이 용이하면서도 안전성을 향상시킨 공기층을 구비한 방음천장이 설치된 터널형 방음시설을 제공함에 본 고안의 목적이 있다.By installing a sound absorbing device composed of a plurality of sound absorbing materials and air layers on the ceiling of the tunnel-type soundproofing facility, it maximizes the sound absorbing area of the noise, maximizes the number of times the noise passes through the sound absorbing material, and maximizes the sound insulation effect. An object of the present invention is to provide a tunnel-type soundproofing facility equipped with a soundproof ceiling having an air layer that is easy to repair and improves safety.

이상과 같은 구성에 의한 본 고안 터널형 방음시설의 작용을 첨부도면에 의해 보다 상세히 설명하면 다음과 같다.When described in more detail by the accompanying drawings the operation of the present invention tunnel-type soundproofing facility by the above configuration as follows.
먼저, 통상의 터널형 방음시설을 살펴보면, 도로변으로 길게 양생된 콘크리트 기초의 상부에 일정간격으로 수직 H-형강을 입설하고, 상기 입설된 수직 H-형강의 대향측에 위치한 또 다른 수직 H-형강을 별도의 수평 H-형강(5)으로 연결하는 것으로서,First, in the conventional tunnel-type soundproofing facility, a vertical H-beam is placed at a predetermined interval on the upper side of the long cured concrete foundation, and another vertical H-beam is located on the opposite side of the vertical H-beam. As a separate horizontal H-beam (5),
상기한 수직 H-형강과 수평 H-형강(5)에는 터널 내부에서 발생하는 소음을 흡수하기 위한 다수의 흡음패널 및 터널 내부의 채광 효과를 갖게 하는 투명패널(2) 및 상기 수평 H-형강(5)의 외부면을 마감하는 상판이 각각 결합되는 것이다.The vertical H-beams and the horizontal H-beams 5 include a plurality of sound absorbing panels for absorbing noise generated inside the tunnel, a transparent panel 2 having a light effect inside the tunnel, and the horizontal H-beams ( The top plate finishing the outer surface of 5) is to be combined respectively.
이와 같이 설치된 터널형 방음시설의 천정내주면에 본 고안의 방음장치를 설치시에는, 도 4의 도시와 같이 H-형강(5)사이에 다수의 "ㅗ"자형 고정대(4)(4')를 직각방향으로 결합하고, 그 사이에 망상의 상,하측커버(1)(2) 및 흡음재(3)로 구성된 방음장치를 삽입하여 체결수단(7)으로 고정하므로서 방음장치의 설치를 완료하는 것이다.When the soundproofing device of the present invention is installed on the ceiling inner circumferential surface of the tunnel-type soundproofing facility installed as described above, as shown in FIG. 4, a plurality of "ㅗ" shaped fixing brackets 4 and 4 'are disposed between the H-shaped steels 5.
