첨부도면을 참조하여 본 발명을 상세히 설명하면 먼저, 도 1과 도 6을 참조하면 본 발명의 방진 패널은 폴리카보네이트(PC)나 스티렌수지(ABS) 재질로 이루어지고 하면은 개방되고 상부는 막힌 형태의 모자 타입으로 이루어진 실린더형 캡(2)과, 상기 캡 내부에 수직 하중 충격시 충격을 완화하는 충격흡수용 방진고무(4)를 내재하여 우레판 발포제시트(8)에 등 간격으로 배열하고, 상기 우레탄 발포제 시트(8)의 저면에 물결 모양으로 골을 만든 골판지(6)를 접착 구성한 것이다.Referring to the accompanying drawings, the present invention will be described in detail. First, referring to FIGS. 1 and 6, the anti-vibration panel of the present invention is made of polycarbonate (PC) or styrene resin (ABS) material, and the lower surface thereof is opened and the upper part is blocked. A cylindrical cap (2) consisting of a hat type and a shock absorbing anti-vibration rubber (4) for alleviating the impact during vertical load shocks in the cap type and arranged at equal intervals in the urethane foam sheet (8), Corrugated cardboard 6 made of corrugated corrugated structure is formed on the bottom of the urethane foam sheet 8.

상기한 캡(2)의 내측은 외벽을 따라 원형의 돌기(10)를 방사상으로 형성하여 방진고무(4)가 끼워질 때 돌기(10)로 인하여 캡(2)의 내벽과 방진고무(4)의 외벽에 자연스럽게 공기흐름이 유도되도록 구성하여 충격음 발생시 공기 흐름에 따라 소음이 분산되도록 유도하여 소음이 방지되도록 한다.The inner side of the cap 2 has a circular protrusion 10 radially along the outer wall to the inner wall of the cap 2 and the anti-vibration rubber 4 due to the protrusions 10 when the anti-vibration rubber 4 is fitted. Air flow is naturally induced on the outer wall of the building so that the noise is dispersed according to the air flow when the impact sound is generated to prevent the noise.

상기한 캡(2)에 내재되는 방진고무는 흡사 M자형으로 구성되어 상면에는 원형돌기(12)를 방사상으로 돌출시켜 캡(2)의 내측면에 접촉 시 방진고무(4)의 상면이 전체적으로 접촉하는 것이 아닌 원형돌기(12)가 접촉되도록 하여 하중을 분산시켜 크기에 비하여 큰 하중을 견딜 수 있도록 구성하고, 중앙부는 V자형의 V홈(14)을 형성하여 충격 발생이 V홈(14) 안으로 방진고무가 일그러지면서 충격을 완화시킬 수 있도록 구성한다.The anti-vibration rubber inherent in the cap 2 has a similar M-shape. The upper surface of the anti-vibration rubber 4 is in total contact with the inner surface of the cap 2 by projecting the circular protrusion 12 radially on the upper surface. The circular protrusions 12 are in contact with each other to disperse the load so as to withstand a large load compared to the size, and the central portion forms a V-shaped V groove 14 so that an impact is generated into the V groove 14. The dust-proof rubber is distorted and configured to alleviate the impact.

또한 방진고무(4) 몸체는 저면 중앙은 돌출되고 외면은 저면 중앙보다 짧은 형태로 구성하여 지면에 닿는 면적을 최대한 줄여 소음이 그만큼 덜 전달되도록 구성한다.In addition, the body of the anti-vibration rubber (4) is configured so that the bottom center is protruding and the outer surface is shorter than the bottom center to reduce the area to reach the ground as much as possible so that the noise is transmitted less.

상기한 우레탄 발포시트에 접착되는 골판지(6)는 물결 모양으로 골을 만든 판지로 구성되어 연속되는 물결무늬의 상하 한 면중 어느 일면이 시트에 접착되며 동일 간격을 유지하여 상하 관통되는 홀(16)을 천공하여 충격음이 홀(16)을 통과하여 골판지의 골 사이로 흘러가도록 유도하여 소음을 최대한 방지할수 있도록 한다.Corrugated cardboard (6) bonded to the urethane foam sheet is composed of a corrugated cardboard made of one side of the upper and lower surfaces of the continuous wave pattern is bonded to the sheet and the same hole to maintain the same interval 16 To perforate the impact sound to pass through the hole 16 between the bones of the corrugated cardboard so as to prevent noise as much as possible.

한편 본 발명은 방진고무(4)의 배열을 사방 1000mm 정도의 시트 크기에 6열 로 배열하거나 또는 10열로 배열할 수 있으며 건축물의 크기와 공간에 따라 적절하게 배열할 수 있다.Meanwhile, the present invention can arrange the anti-vibration rubber 4 in 6 rows or 10 rows in a sheet size of about 1000 mm in all directions, and can be appropriately arranged according to the size and space of the building.

상기와 같이 구성된 본 발명은 통상의 건축물의 설치 시 방진고무가 등 간격으로 배열된 우레탄 발포제 시트(8)를 통상의 방진 패널과 마찬가지로 건물의 바닥에 올려놓고 기포 콘크리트와 발포 콘크리트를 시트의 상면에 작업하면 되는 것이고 이때 건축물의 크기에 따라 시트의 재질이 우레탄 발포 시트이므로 쉽게 절단되어 작업상의 단점이 없이 간편하게 작업할 수 있다.According to the present invention configured as described above, the urethane foam sheet 8, which is arranged at regular intervals in the installation of a normal building, is placed on the floor of a building like a normal dustproof panel, and foamed concrete and foamed concrete are placed on the upper surface of the sheet. The material of the sheet is urethane foam sheet according to the size of the building, so it can be easily cut and can be easily worked without any drawbacks.

따라서 콘크리트 작업 후 상하층의 사이에 시트가 위치하게 되면 상하층에 시트로 인한 분리된 공간이 생기게 되고 상층에서 수직하중이 발생하면 1차로 캡(2)에서 충격을 받고 이 충격은 방진고무(4)로 전달된다.Therefore, if the seat is positioned between the upper and lower layers after concrete work, a separate space is created by the upper and lower layers, and when a vertical load occurs in the upper layer, the shock is firstly received from the cap (2), and the impact is anti-vibration rubber (4 Is delivered.

전달된 충격은 캡(2)의 안쪽에 위치된 방진고무(4)의 상면에 전달되며 이때 방진고무(4)는 재질상의 장점으로 인하여 충격을 흡수하면서 방진고무의 상면에 돌설된 원형돌기(12)의 완충역활에 따라 충격이 분산되고 충격음은 캡(2)의 내벽과 방진고무(4)의 외벽 사이의 공간으로 흘러가게 되면서 공기흐름에 의하여 소음이 분산된다.The transmitted shock is transmitted to the upper surface of the anti-vibration rubber 4 located inside the cap 2, wherein the anti-vibration rubber 4 protrudes on the upper surface of the anti-vibration rubber while absorbing the shock due to material advantages. The shock is dispersed according to the buffering role of), and the impact sound flows into the space between the inner wall of the cap 2 and the outer wall of the dustproof rubber 4, and the noise is dispersed by the air flow.

분산된 소음은 최종 골판지(6)로 유도되고 골판지에는 관통된 홀(16)이 천공되어 소음이 골판지의 골을 따라 흘러가게 되므로 수직하중에 따라 발생되는 소음이 자연스럽게 완화 되는 것이다.Dispersed noise is guided to the final cardboard (6) and the perforated hole (16) is drilled in the corrugated cardboard so that the noise flows along the corrugated cardboard, so that the noise generated by the vertical load is naturally relieved.

이때 수직하중에 따라 방진고무가 충격을 받게 되면 충격을 받은 방진고무(4)는 중앙의 V자 홈에 의하여 중앙으로 일그러지면서 충격을 흡수하고 방진고무 는 상면보다 저면의 닿는 부분이 적어 그만큼 하층에 충격이 발생되는 것이 적어지게 되는 것이다.At this time, when the anti-vibration rubber is impacted by the vertical load, the shock-proof anti-vibration rubber (4) is distorted to the center by the V-shaped groove in the center to absorb the shock, and the anti-vibration rubber has less contact with the bottom than the upper surface. The less shock is generated.

따라서 충격음을 완벽하게 줄여 충격소음이 없게 되는 것이다.Therefore, the impact noise is completely reduced and there is no impact noise.

상술한 바와 같이 본 발명은 방진고무에서 충격을 흡수하고 충격음을 분산 유도하여 충격을 완화시켜 주므로 아파트 등의 층간 소음방지용 등 다양한 용도로 사용가능한 장점이 있는 발명인 것이다.As described above, the present invention is an invention having advantages in that it can be used for various purposes, such as for preventing noise between floors, such as apartments, by absorbing shocks and inducing shock sounds to induce shocks.
