본 발명에 의한 발포콘크리트를 이용한 방음벽은 도로의 가장자리를 따라 설치되는 콘크리트옹벽(10)과, 상기 콘크리트옹벽(10)의 상면에 설치되는 H빔(20)과, 상기 H빔(20) 사이에 적층되는 방음패널(30)과, 가장 상측에 적층된 방음패널(30)의 상단에 설치되는 덮개(40)로 구성된다.The soundproof wall using foamed concrete according to the present invention includes a concrete retaining wall 10 installed along an edge of a road, an H beam 20 provided on an upper surface of the concrete retaining wall 10, and the H beam 20. It is composed of a soundproof panel 30 to be laminated, and a cover 40 provided on the upper end of the soundproof panel 30 stacked on the uppermost side.

상기 콘크리트옹벽(10)은 상면에 설치되는 H빔(20)과 방음패널(30)의 안정적 설치와 가드레일의 역할을 고려했을 때 상면은 좁고 하면은 넓은 상광하협(上廣下(狹)의 형태로 구성하는 것이 바람직하다.The concrete retaining wall 10 has a narrow upper surface and a wider lower surface of the lower surface when considering the role of the guardrail and the stable installation of the H beam 20 and the soundproof panel 30 installed on the upper surface. It is preferable to configure in a form.

상기 H빔(20)은 상기 콘크리트옹벽(10)의 상면에 일정간격을 유지하면서 앵커볼트에 의하여 복수개가 설치/고정되는 것으로, 알루미늄이나 스테인레스 스틸로 제작하여 부식을 방지하고 차량의 매연 등에 대한 저항력을 향상시킨다. 그리고 H빔(20)은 그 자체적 형상으로 인하여 양측면에 상기 방음패널(30)이 설치되는 착탈홈(21)이 형성된다.The H beam 20 is to be installed / fixed by a plurality of anchor bolts while maintaining a predetermined interval on the upper surface of the concrete retaining wall 10, made of aluminum or stainless steel to prevent corrosion and resistance to smoke of the vehicle, etc. To improve. In addition, the H beam 20 has a detachable groove 21 in which the soundproof panel 30 is installed on both sides due to its own shape.

이러한 H빔(20)의 전면, 즉 도로쪽에 위치되는 H빔(20)의 면에는 장식패널(22)을 부착한다. 도면에 도시된 H빔(20)의 장식패널(22)은 중앙에 형성된 일정곡률의 원형패널과, 상기 원형패널의 양측에 형성되고 중앙의 원형패널보다 그 크기가 작은 원형패널로 구성되었으나, 이러한 형태는 하나의 실시예에 불과한 것이고, 장식패널(22)의 형태는 미관을 향상시키는 목적이라면 어느 형태이건 가능하다 할 것이다.The decorative panel 22 is attached to the front surface of the H beam 20, that is, the surface of the H beam 20 located on the road side. The decorative panel 22 of the H beam 20 shown in the drawing is composed of a circular panel having a constant curvature formed in the center and a circular panel formed on both sides of the circular panel and smaller in size than the circular panel in the center. The shape is only one embodiment, the shape of the decorative panel 22 may be any shape as long as the purpose of improving the aesthetics.

상기 방음패널(30)은 규석분말, 생석회, 석고분말, 시멘트, 물, 제오라이트, 벤토나이트, 그리고 발포제인 알루미늄분말이 일정비율로 혼합되어 건조/양생되고, 와이어메쉬(31a)가 내장되며, 후면에 방수재가 코팅된 발포콘크리트패널(31)과, 상기 발포콘크리트패널(31)의 테두리에 결합되고 상기 H빔(20) 사이에 삽입되는 프레임(32)으로 구성된다.The soundproof panel 30 is a mixture of silica powder, quicklime, gypsum powder, cement, water, zeolite, bentonite, and an aluminum powder which is a blowing agent in a proportion to dry / curing, wire mesh (31a) is built, the rear It is composed of a foamed concrete panel 31 coated with a waterproof material, and a frame 32 coupled to the edge of the foamed concrete panel 31 and inserted between the H beams 20.

여기서, 상기 발포콘크리트패널(31)의 제작과정을 상술하면, 규석분말, 생석회, 석고분말, 시멘트, 제오라이트, 벤토나이트, 물을 일정비율로 혼합하고, 여기에 발포제인 알루미늄분말을 일정량 첨가하여 혼합함으로써 그 조정물이 이루어지고, 이렇게 이루어진 혼합조성물을 금형에 공급하여 건조시킨 후에 탈형시킨다. 이때, 상기 혼합조성물 내부에는 와이어메쉬(31a)를 배치시켜 이후에 제작될 발포콘크리트패널(31)의 강성을 향상시키도록 한다.Here, in detail the manufacturing process of the foamed concrete panel 31, by mixing the silica powder, quicklime, gypsum powder, cement, zeolite, bentonite, water in a certain ratio, and by adding a predetermined amount of aluminum powder as a foaming agent The adjustment is made, and the mixed composition thus formed is supplied to a mold, dried, and demolded. At this time, by placing the wire mesh 31a in the mixed composition to improve the rigidity of the foamed concrete panel 31 to be produced later.

상기한 것처럼 와이어메쉬(31a)가 내장된 발포콘크리트패널(31)이 제작된 후에는 이것을 양생기 내에 일정 시간동안 수납시켜 건조/양생시킴으로써 발포콘크리트패널(31)이 완성된다.As described above, after the foamed concrete panel 31 in which the wire mesh 31a is embedded is manufactured, the foamed concrete panel 31 is completed by storing it in a curing machine for a predetermined time and drying / curing it.

Of course, it is possible to coat the waterproofing material on the front surface of the foam concrete panel 31, but if the waterproofing material is coated on the front surface, the noise absorption ability is reduced, it is preferable to coat the waterproofing material only on the rear surface of the foamed concrete panel 31.

그리고, 발포콘크리트패널(31)의 전면에는 복수개의 요홈부(31b)를 수평방향으로 일정한 간격을 이루도록 형성시킨다. 이렇게 요홈부(31b)가 형성되면 종래에 그 면이 평평하게 형성된 방음벽보다 소음흡수능력을 향상시킬 수 있다.Then, the front surface of the foam concrete panel 31 is formed with a plurality of grooves (31b) to form a constant interval in the horizontal direction. If the groove portion 31b is formed in this way, the sound absorbing ability can be improved compared to the soundproof wall having a flat surface in the related art.

상기 프레임(32)은 그 형태를 다양하게 구성할 수 있는데, 먼저 종래와 같이 일반적인 액자 형태로 제작하여 상기 발포콘크리트패널(31)의 테두리를 감싸도록 할 수도 있고, 상기 발포콘크리트패널(31)의 테두리를 감싸면서 후면은 개방되고 전면은 밀폐되게 구성할 수도 있으며, 상기 발포콘크리트패널(31)의 테두리를 감싸는 액자형태로 구성하면서 발포콘크리트패널(31)의 전면에 요철이 형성된 알루미늄 타공판(32a)을 설치하여 발포콘크리트패널(31)의 전면을 밀폐할 수도 있다.The frame 32 may be configured in various forms. First, the frame 32 may be manufactured in a general frame shape to surround the edge of the foamed concrete panel 31, and the foamed concrete panel 31 may be formed.
