Description

합성수지재를 사용한 소음 간섭형 가설 방음판{noise interference type temporary soundproof board using sythetic resin materail}[0001] The present invention relates to a noise interference type temporary soundproof board using a synthetic resin material,

본 발명은 합성수지재를 사용한 소음 간섭형 가설 방음판에 관한 것으로서,더욱 상세하게는 열가소성 합성수지재의 적용을 통한 압출 금형으로 간단하게 성형 제작할 수 있도록 하며, 소음을 다중회절원리에 의해 흡수 및 소멸하게 함으로써 소음의 외부 전달을 차단할 수 있도록 한 소음 간섭형 가설 방음판에 관한 것이다.More particularly, the present invention relates to a sound absorbing type sound absorbing plate using a synthetic resin material, and more particularly, to a sound absorbing plate capable of being easily formed by an extrusion die through the application of a thermoplastic synthetic resin material and absorbing and extinguishing noise by a multiple diffraction principle, Which is capable of blocking the external transmission of the noise interference type building.

일반적으로 건설현장에서는 공사 관련한 소음이 심하게 발생하며, 이러한 소음은 현장 주변에 위치한 주택, 사무실 또는 학교 등에 심각한 소음 공해를 유발하게 된다. Generally, in the construction site, the construction noise is generated severely, and such noise causes severe noise pollution in houses, offices or schools located around the site.

이렇게 건설현장에서 발생하는 소음을 차단하고 보행자의 안전을 위하여 가설 방음판을 설치하게 되며, 공사가 완료되면, 상기 가설 방음판을 철거하게 된다.In this way, the noise generated in the construction site is blocked, and the temporary sound insulation board is installed for the safety of the pedestrian. When the construction is completed, the temporary sound insulation board is removed.

이와 같이, 종래 적용되고 있는 가설용 방음판은 대부분이 내구성을 위해 알루미늄이나 철판 또는 아연도금강판 등의 금속재를 사용하고 있고, 타공 구조를 포함하는 형태를 취하고 있으며, 판형의 후면패널 등에 체결하여 사용하고 있다.As described above, most of the conventional soundproofing boards for use in the present invention use metallic materials such as aluminum, iron plate, or galvanized steel plate for durability, and they include a perforated structure. They are fastened to a plate- have.

이러한 금속재 가설 방음판은 설치 및 철거의 어려움이 있으며, 제조단가가 비교적 높은 단점이 있다.Such a metal plate is difficult to install and demount, and the manufacturing cost is relatively high.

이러한 문제점을 개선하기 위해 합성수지재를 사용한 가설 방음판의 구조로, 전면판과 후면판 사이의 흡음재를 고정하기 위해 나사못으로 고정하여 사용 하고 있다.In order to solve these problems, a structure of a hypothetical soundproof plate using a synthetic resin material is used and fixed with a screw to fix the sound absorbing material between the front plate and the back plate.

또한, 전면판 한쪽만 사용하기 위해 공사현장 방향 면 쪽으로 수개의 구멍을 가공하고 내측 공간에 흡음재를 채워 사용하고 있다.Also, in order to use only one side of the front plate, several holes are machined toward the direction of the construction site and a sound absorbing material is filled in the inner space.

종래의 가설 방음판은 설치 및 제조방법, 재사용의 어려움을 가지며 공사기간과 공사비에 영향을 주는 단점이 있다.Conventional conventional soundproofing panels have disadvantages in that they have a difficulty in installation and manufacturing methods and reuse, and they affect the construction period and construction cost.
