The perforated plate 10 is preferably formed of a strong material, such as polycarbonate or carbon fiber, which does not break even when people step on it in contact with the grating. The perforated plate 10 is formed by perforating the holes 30 at regular intervals in the plate made of the material.
도 4에서 보이는 바와 같이, 상기 타공판(10)에 상기 타공판(10)에 형성된 구멍(30)보다 조금 작은 직경을 갖는 반원뿔 형상의 기둥(41)을 삽입한다. 상기 반원뿔 형상의 기둥(41)은 상기 구멍(30)의 직경보다 작으므로 상기 반원뿔 형상의 기둥(41)과 상기 구멍(30) 사이에는 이격된 공간이 형성되는 데, 도 5에 도시된 바와 같이 상기 반원뿔 형상의 기둥(41)의 외주면과 상기 구멍(30)의 내주면이 완전히 이격되도록 하는 것이 바람직하다.As shown in FIG. 4, a semiconical pillar 41 having a diameter slightly smaller than that of the hole 30 formed in the perforated plate 10 is inserted into the perforated plate 10. Since the semi-conical pillar 41 is smaller than the diameter of the hole 30, a space is formed between the semi-conical pillar 41 and the hole 30, which is shown in FIG. As described above, the outer circumferential surface of the semi-conical pillar 41 and the inner circumferential surface of the hole 30 may be completely separated from each other.
상기 반원뿔 형상 기둥(41)은 기둥 고정판(40)의 상부로 돌출되어 형성된다. 상기 반원뿔 형상 기둥(41)은 반원뿔 형상 기둥 아래에 볼트(42)가 형성되며, 상기 기둥 고정판(40)에는 상기 볼트(42)가 끼워질 수 있는 구멍이 형성되어, 상기 반원뿔 형상 기둥(41)이 상기 기둥 고정판(40)에 끼워져서 고정될 수 있다.The semi-conical pillar 41 is formed to protrude to the top of the column fixing plate (40). The semi-conical pillar 41 is a bolt 42 is formed below the semi-conical pillar, the pillar fixing plate 40 is formed with a hole for the bolt 42 is fitted, the semi-conical pillar 41 may be fitted to the pillar fixing plate 40 to be fixed.
한편, 상기 반원뿔 형상 기둥(41)이 상기 구멍(30)에 삽입되고 나면, 도 6에서와 같이, 상기 타공판(10)의 상부에 우레탄 수지 등의 탄성 물질을 도포하여 상부층(20)을 형성한다. 이 때 상기 상부층(20)의 높이는 상기 기둥(41)의 높이와 동일하게 형성되도록 하며, 상기 탄성 물질 도포시, 상기 반원뿔 형상 기둥(41)과 상기 구멍(30)의 이격된 공간 사이로도 탄성 물질이 도포되어 이격된 공간을 메우게 된다.On the other hand, after the semi-conical pillar 41 is inserted into the hole 30, as shown in Figure 6, to form an upper layer 20 by applying an elastic material such as urethane resin on top of the perforated plate 10. do. In this case, the height of the upper layer 20 is formed to be the same as the height of the pillar 41, and when the elastic material is applied, the semi-conical pillar 41 and the space between the spaced space of the hole 30 is also elastic The material is applied to fill the spaces spaced apart.
이 후, 상기 기둥 고정판(40)을 떼어내게 되면, 본 발명에 의한 그레이팅 안전 덮개가 형성된다.After that, when the pillar fixing plate 40 is removed, the grating safety cover according to the present invention is formed.
한편, 상기 반원뿔 형상 기둥(41)이 삽입된 채로 상기 타공층(10)에 상부층을 형성하는 물질을 도포하여 상부층(20)을 형성하는 단계에 있어, 도포된 상부층(20)상에 그레이팅 안전 덮개 성형판(50)을 덮는 단계를 추가하고,Meanwhile, in the step of forming the upper layer 20 by applying a material forming the upper layer to the perforated layer 10 with the semi-conical pillar 41 inserted therein, grating safety on the applied upper layer 20. Add the step of covering the lid molding plate 50,
이 후 상기 그레이팅 안전 덮개 성형판(50)을 분리하는 단계를 추가로 포함할 수 있으며, 이 후 상기 기둥 고정판(40)과 상기 그레이팅 안전 덮개 성형판(50)을 분리하면, 본 발명에 의한 그레이팅 안전 덮개가 형성된다.Thereafter, the method may further include a step of separating the grating safety cover molding plate 50, and after separating the pillar fixing plate 40 and the grating safety cover molding plate 50, the grating according to the present invention. Safety cover is formed.
상기와 같은 방법으로 제조된 그레이팅 안전 덮개는 타공판(10)을 상부층(20)이 감싸는 형태로 형성되고, 특히, 반원뿔형 구멍(70)이 형성되므로, 협잡물 등이 구멍으로 들어오더라도 하방의 직경이 더 커지는 구조적 특성상 구멍이 막히지 않고 곧바로 빠지게 되고, 우레탄 등의 탄성 물질이 상부층(20)을 형성하고 있어, 쉽게 파손되지 않고 오히려 사람이나 물체가 지나갈 때 적당한 탄성이 구멍에 전달되어 협잡물 등의 물질이 잘 배출되게 하여 준다.The grating safety cover manufactured by the above method is formed in a form in which the upper layer 20 surrounds the perforated plate 10, and in particular, since the semi-conical hole 70 is formed, the diameter of the lower part even when a contaminant or the like enters the hole. Due to this larger structural characteristic, the hole is not clogged and immediately falls out, and an elastic material such as urethane forms the upper layer 20, so that it is not easily broken, but rather, when a person or an object passes by, an appropriate elasticity is transferred to the hole and a substance such as a contaminant. Allow this to drain well.
본 실시예에서는 타공판은 390mm × 985mm 폴리카보네이트(Poly Carbonate)판에 직경 15mm 구멍을 20피치 간격으로 형성하였다.In the present embodiment, the perforated plate was formed in a 390 mm × 985 mm polycarbonate plate with a 15 mm diameter hole at 20 pitch intervals.
기둥 고정판은 400mm × 1,000mm 철판으로 형성하였고, 하단의 직경이 14mm, 상단의 직경이 7mm, 높이가 7mm인 반원뿔 형상 기둥이 20피치 간격으로 고정되었다.The column fixing plate was formed of a 400mm × 1,000mm iron plate, and a semiconical column having a diameter of 14mm at the bottom, a diameter of 7mm at the top, and a height of 7mm was fixed at 20 pitch intervals.
그레이팅 안전 덮개 성형판은 가장자리에 9mm높이의 벽이 형성된 400mm × 1,000mm 철판으로 형성하였다.The grating safety cover molding plate was formed from a 400 mm x 1,000 mm iron plate with a 9 mm high wall at the edge.
타공판의 구멍에 상기 기둥 고정판의 반원뿔 형상 기둥이 삽입시키고, 타공판이 흔들리지 않도록 핀 등을 사용하여 고정시킨다.The semiconical column of the column fixing plate is inserted into the hole of the perforated plate, and fixed using a pin or the like so that the perforated plate does not shake.
상기 그레이팅 안전 덮개 성형판 바닥면에는 그레이팅 안전 덮개 상부면에 골을 형성하여 줄 수 있게 골 성형틀(51)이 양각되어 있다. 상기 양각된 골 성형틀상에 상기 반원뿔 형상 기둥이 위치할 수 있도록 하는 것이 바람직하고, 그 결과 상기 그레이팅 안전 덮개 성형판을 제거하였을 때 골 내부에 구멍이 위치되어 배수가 원활하게 이루어질 수 있다.On the bottom surface of the grating safety cover molding plate, a bone molding frame 51 is embossed so as to form a bone on the grating safety cover upper surface. Preferably, the semi-conical pillars may be positioned on the embossed bone mold, and as a result, when the grating safety cover mold plate is removed, a hole may be positioned in the bone to allow for smooth drainage.
상기 그레이팅 안전 덮개 성형판에 상기 기둥 고정판에 고정된 상기 타공판을 배치시킨다. 타공판은 그레이팅 안전 덮개 성형판보다 작은 크기로 형성되었으므로 그레이팅 안전 덮개 성형판의 가장자리에 형성된 벽 내부 공간에 들어갈 수 있다. 그 상태에서 우레탄 수지액을 주입한다. 우레탄 수지는 그레이팅 안전 덮개 성형판과 기둥 고정판 사이 내부 공간에 주입되게 되고, 그 결과 타공판의 구멍은 물론이고 타공판을 전체적으로 감싸게 된다.The perforated plate fixed to the pillar fixing plate is disposed on the grating safety cover molding plate. Since the perforated plate is formed to be smaller than the grating safety cover molding plate, it can enter the wall inner space formed at the edge of the grating safety cover molding plate. In that state, urethane resin liquid is inject | poured. The urethane resin is injected into the inner space between the grating safety cover molding plate and the column fixing plate, and as a result, the perforated plate as well as the hole of the perforated plate as a whole wrap.
우레탄 수지가 굳게 되면 그레이팅 안전 덮개와 기둥 고정판을 제거하고, 양생단계를 거치고, 최종적으로 마무리 성형 작업을 하면 그레이팅 안전 덮개가 만들어지게 된다.When the urethane resin is hardened, the grating safety cover is removed by removing the grating safety cover and the column fixing plate, undergoing curing, and finally finishing molding.
본 발명은 배수가 잘 되게 하면서도 신발의 굽, 유모차 바퀴, 그 외 물건 등이 쉽게 빠지지 않는 안전 그레이팅에 관한 것이다.The present invention relates to a safety grating that drains well but does not easily fall out of a heel of a shoe, a baby carriage wheel, and other objects.
