본 고안은 각종 토목 공사 또는 건설 공사 등의 현장에 설치되는 가설 방음판에 관한 것으로, 더욱 상세하게는 가설 방음판의 일면에 소음을 안내하는 타공면과 소음을 반사시키는 반사면이 반복 형성되도록 하여 가설 방음판에 적용된 흡음재의 소음 흡수능력에 대응하는 소음의 유입 및 차단이 이루어질 수 있도록 한 흡차음 겸용 가설 방음판에 관한 것이다.The present invention relates to a temporary soundproofing plate installed at a site such as various civil works or construction work, and more specifically, a temporary soundproofing board is formed by repeatedly forming a perforated surface guiding noise and a reflective surface reflecting the noise on one surface of the temporary soundproofing board. The present invention relates to a sound absorbing and insulating plate for both sound absorbing and soundproofing, which enables the inflow and blocking of noise corresponding to the sound absorbing ability of the sound absorbing material applied to the sound absorbing material.

일반적으로, 가설 방음판은 각종 토목 공사 또는 건설 공사의 현장 외곽에 설치되어 현장 내부에서 발생하는 각종 소음 및 비산먼지 등이 외부로 전파되는 것을 차단하기 위하여 임시로 설치되는 것이다.In general, the temporary sound insulation board is installed on the outside of the site of various civil works or construction work is temporarily installed in order to block the propagation of various noises and scattering dust generated inside the site to the outside.

이러한 가설 방음판은, 통상적으로 금속의 재질로 이루어지며, 일면에 각종 소음 및 비산먼지가 유입될 수 있도록 소음안내홀이 천공되어 있는 전면판과, 상기 전면판의 후면에 결합되는 후면판 및 상기 전면판 및 후면판의 사이에 개재되어 전면판의 소음안내홀을 통해 유입되는 소음 및 비산먼지를 흡음하게 되는 흡음재로 구성된다. Such a temporary soundproofing plate is typically made of a metal material, the front plate is perforated with a noise guide hole so that various noise and scattering dust flows into one surface, the back plate and the front surface are coupled to the rear of the front plate It is composed of a sound absorbing material interposed between the plate and the rear plate to absorb the noise and scattering dust flowing through the noise guide hole of the front plate.

상기와 같이 구성된 가설 방음판은 공사 현장의 외관에 등간격으로 설치되는 지주에 하향 적층시켜 사용하게 되며, 이후 공사 현장에서 소음 및 비산먼지가 발생할 경우 가설 방음판에 의해 차단되어 이웃 건물로 전달되는 것을 방지하게 된다. Temporary soundproof boards configured as described above are used by stacking them downward on posts that are installed at equal intervals on the exterior of construction sites, and then prevent noise and scattering dust from being blocked by temporary soundproof panels at construction sites to prevent transfer to neighboring buildings. Done.

하지만, 상기한 가설 방음판의 경우 경제적 비용을 절감하고자 일반 보존형 방음판의 두께에 비해 상대적으로 얇게 제작되어 현장에 설치되는 바 가설 방음판내에 제공되는 흡음재의 두께가 얇아 전면판에 형성된 소음안내홀로 소음이 유입되 는 경우 흡음재가 이를 완전하게 흡음하지 못하고 일부를 외부로 전달하게 되어 주민의 민원이 발생되는 문제점이 있었다.However, in the case of the above-mentioned temporary soundproofing boards, in order to reduce economic costs, the thickness of the sound absorbing material provided in the temporary soundproofing boards is relatively thin compared to the thickness of the general preservation type soundproofing boards and installed in the field. In case of inflow, the sound absorbing material did not completely absorb the sound, and some of the sound absorbing materials were delivered to the outside, resulting in complaints of residents.

이에 본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로, 본 고안의 목적은, 가설 방음판에 제공되는 흡음재의 흡음능력에 대응하는 소음만이 흡음재로 유입될 수 있도록 하여 외부로 통과되는 소음을 최소화시키고자 하는데 있다.The present invention is devised to solve the above problems, an object of the present invention, so that only the noise corresponding to the sound absorbing ability of the sound absorbing material provided in the temporary soundproofing plate to be introduced into the sound absorbing material to minimize the noise passing outside.

In manufacturing, as shown in FIG. 1, the plate-shaped frame is formed to repeat the perforated surface 110 and the reflective surface 120 through a press mechanism, and then a punching device (not shown) on the perforated surface 110. Through the plurality of holes 111 are formed. At this time, the hole 111 is formed in a circular, long hole, star hole, triangular hole, square hole, diamond hole and the like according to the application and the application. Continuously forming the bent portion 130 in the 'b' shape on the upper end and the bent portion 131 in the 'U' shape on the lower end to form the front frame 100 is completed. Here, of course, it is also possible to use a single press work during the above operation.

이후, 다른 프레임을 프레스 기기를 통해 상·하단부에 절곡부(210,211)가 형성되도록 절곡 형성시킨 다음, 하단부의 절곡부(211)에는 하향으로 수직단(220)을 절곡 형성시켜 후방 프레임(200)을 완성한다.Thereafter, the other frame is bent to form the bent portions 210 and 211 at the upper and lower ends through the press machine, and then the vertical end 220 is bent downwardly formed at the bent portion 211 at the lower end of the rear frame 200. To complete.

그런다음, 전후방 프레임(100)(200)의 사이에 흡음재(300)를 결합시킨후, 상기 후방 프레임(200)의 하측 절곡부(211)를 전방 프레임(100)의 'U'자 형상의 걸림부(131)에 끼움 결합시키고, 연속해서 상측 절곡부(210)를 'ㄱ' 자 형상의 걸림부(130)에 끼움 결합시켜 고정하게 되면 하나의 가설 방음판이 완료된다.Then, after the sound absorbing material 300 is coupled between the front and rear frames 100 and 200, the lower bent portion 211 of the rear frame 200 is caught in a 'U' shape of the front frame 100. When the fitting portion 131 is inserted, and the upper bent portion 210 is continuously coupled to and fixed to the 'b' shaped locking portion 130, one hypothesis soundproof plate is completed.

이와 같이 제작된 가설 방음판들을 설치 장소에 세워진 지주들 사이에 적층 결합시키면 가설 방음벽이 완성되게 된다. When the temporary sound insulation boards manufactured as described above are laminated and bonded between the props erected at the installation site, the temporary soundproof walls are completed.

이와같이 설치된 가설 방음판에 소음이 발생하게 되면 소음의 일부는 전방 프레임(100)의 타공면(110)에 형성된 구멍(111)을 통해 흡입되어 상기 흡음재(300)에 의해 흡음 되어지며, 소음의 일부는 반사면(120)과 경사면(130)을 통해 사방으로 반사되어 자연 소멸되거나 소음원 발생지역에서 소멸된다. When noise is generated in the installed temporary sound insulation board, a part of the noise is sucked through the hole 111 formed in the perforated surface 110 of the front frame 100 and is absorbed by the sound absorbing material 300. Reflected in all directions through the reflecting surface 120 and the inclined surface 130, the natural disappears or disappears in the noise source generation area.

도 3은 본 고안의 가설 방음판에서 전방 프레임(100)의 다른 실시예를 도시한 것이며, 이는 상기 반사면(120)의 상측 단부와 연결되는 상기 타공면(110)의 절곡부위는 소정각도 경사진 경사면(130)을 형성하고, 상기 반사면(120)의 하측 단부와 연결되는 상기 타공면(110)의 절곡부위는 직립단(140)을 형성하여 상기 경사면(130)과 직립단(140)을 통해 소음의 간섭을 유도할 수 있는 것이다. Figure 3 shows another embodiment of the front frame 100 in the hypothesis soundproof plate of the present invention, which is bent portion of the perforated surface 110 is connected to the upper end of the reflective surface 120 is inclined at a predetermined angle The inclined surface 130 is formed, and the bent portion of the perforated surface 110 connected to the lower end of the reflective surface 120 forms an upright end 140 to form the inclined surface 130 and the upright end 140. Through this, the interference of noise can be induced.
