수도계량기함용 전면커버의 제조방법{MANUFACTURING METHOD OF FRONT COVER FOR WATER METER BOX}{MANUFACTURING METHOD OF FRONT COVER FOR WATER METER BOX}

본 발명은 수도계량기함용 전면커버의 제조방법에 관한 것으로, 더욱 상세하게는 전면커버의 중앙에 개폐도어가 구비되어 전면커버의 점검창에 용이하게 탈착할 수 있으며, 점검창을 통해 용이하게 수도계량기를 검침 또는 점검할 수 있으며, 전면커버의 점검창에 개폐도어가 기밀이 유지되도록 밀폐되어 외부의 이물질이 수도계량기함 내부로 유입되는 것을 방지할 수 있고, 동절기에 외부의 찬공기가 수도계량기함 내부로 유입되는 것을 방지할 수 있고, 전면커버와 개폐도어의 배면에 단열재가 부착되어 수도계량기함을 보온하여 동절기에 수도계량기의 동파를 방지할 수 있으며, 전면커버와 개폐도어의 제조공정이 간단하여 생산성을 향상시킬 수 있는 수도계량기함용 전면커버의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a front cover for a water meter box. More specifically, the front cover is provided with an opening and closing door in the center so that it can be easily attached and detached from the inspection window of the front cover, and the water meter can be easily installed through the inspection window. You can read or inspect the meter, and the opening/closing door on the inspection window on the front cover is sealed to maintain airtightness to prevent external foreign substances from entering the water meter box, and in the winter, cold outside air can enter the water meter box. It can prevent water from flowing inside, and the front cover and door have insulation attached to the back of the door to keep the water meter box warm and prevent the water meter from freezing during the winter. The manufacturing process for the front cover and door is simple. This relates to a method of manufacturing a front cover for a water meter box that can improve productivity.

일반적으로 모든 가정 또는 업소 등에는 식수, 용수로서 수돗물을 이용하고 있으며, 이러한 수돗물은 상수도관을 통하여 각 가정 또는 업소 등으로 공급되고, 그 수돗물의 공급량을 자동으로 측정하기 위하여 수도계량기가 설치된다.In general, all homes or businesses use tap water as drinking water or water. This tap water is supplied to each home or business through water pipes, and a water meter is installed to automatically measure the amount of tap water supplied.

그리고 상기와 같이 상수도관을 통해 공급되는 수돗물은 추운 동절기에 기온이 급강하할 경우 상수도관 또는 수도계량기 내부에서 결빙되어 그 부피가 커지게 되고, 이로 인하여 수도관 또는 수도계량기가 동파되는 문제점이 있었다.In addition, as described above, when the temperature of tap water supplied through water pipes drops sharply during the cold winter season, it freezes inside the water pipes or water meters and increases in volume, which causes the water pipes or water meters to freeze and burst.

종래에는 동절기에 동파현상을 방지하기 위하여 수도관과 수도계량기를 모두 지하에 매설하는 방식을 이용되고 있다,Conventionally, the method of burying both water pipes and water meters underground is used to prevent freezing and bursting during the winter.

그러나, 오늘날 보편화되고 있는 연립주택, 빌라, 아파트 등의 공동주택에는 수도관이 콘크리트 벽체 내에 매설되는 반면에 수도계량기는 관리자가 수돗물의 공급량을 수시로 확인하여야 하므로 벽체의 내부에 매설되도록 설치되지만 외부에서 관찰할 수 있도록 외부로 노출된 상태로 설치된다.However, while water pipes are buried within concrete walls in apartment complexes such as townhouses, villas, and apartments, which are becoming more common today, water meters are installed to be buried inside the wall because managers must frequently check the amount of tap water supplied, but are observed from the outside. It is installed exposed to the outside so that it can be installed.

이러한 수도계량기는 벽면에 매설되는 수도계량기함 내부에 내장되도록 설치되어 보호되며, 벽면에 매설되는 상기 수도계량기함의 전면에는 전면커버가 결합되며, 상기 전면커버에는 검침원이 수도계량기을 점검 또는 검침할 수 있도록 개폐가 가능한 도어가 결합된다.This water meter is installed and protected inside a water meter box embedded in the wall, and a front cover is attached to the front of the water meter box embedded in the wall, and the front cover allows a meter reader to check or read the water meter. A door that can be opened and closed is combined.

그러나 종래의 수도계량기함은 외부의 충격에 의해 도어가 굴곡되거나 파손되면 전면커버로부터 도어를 열기 불편한 문제점이 있었다.However, the conventional water meter box had a problem in that it was inconvenient to open the door from the front cover if the door was bent or damaged due to an external impact.

그리고 상기 도어와 전면커버의 사이가 완전히 밀폐되지 않아 동절기에 찬공기가 전면커버와 도어 사이를 통해 수도계량기함 내부로 유입되어 수도관 또는 수도계량기가 동파되는 문제점이 있었다.Also, because the space between the door and the front cover was not completely sealed, there was a problem in the winter when cold air flowed into the water meter box through the front cover and the door, causing the water pipe or water meter to freeze and burst.

즉 대부분의 공동주택에 있어서, 상기와 같은 수도계량기함을 대부분 설치하고 있음에도 동절기 한파가 닥쳐올 경우 응급처치로 수도계량기함 외부에 신문지 또는 두꺼운 박스 등으로 덮어 단열을 하고 있으나, 이는 실제로 보온효과를 갖지 못하게 되어 수도관이나 수도계량기에 동파가 발생하게 되는 문제점이 있었다.In other words, in most apartment complexes, even though most of the above-mentioned water meter boxes are installed, when a cold wave approaches during the winter, the outside of the water meter box is insulated by covering it with newspaper or a thick box as an emergency measure. However, this does not actually have a warming effect. There was a problem of freezing and bursting of water pipes and water meters due to lack of water.

또한 상기와 같은 종래의 수도계량기함용 전면커버와 도어는 그 제조공정이 복잡하여 생산성이 떨어지고, 제조단가가 상승하게 되는 문제점이 있었다.In addition, the front cover and door for the conventional water meter box as described above have problems in that the manufacturing process is complicated, which reduces productivity and increases the manufacturing cost.

본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.A preferred embodiment of the present invention will be described in detail with the accompanying drawings as follows.

본 발명에 따른 수도계량기함용 전면커버의 제조방법은 도 1에 도시된 바와 같이 절단기(100)를 이용하여 스테인레스 판재(200)에서 수도계량기함용 전면커버 본체(300)의 크기로 절단(S100)하며, 도 2에 도시된 바와 같이 성형기(400)를 이용하여 상기 절단된 전면커버 본체(300)의 테두리가 직각으로 굴곡되도록 판금 성형(drawing)(S200)한다.The method of manufacturing the front cover for a water meter box according to the present invention is to cut the stainless steel plate 200 to the size of the front cover body 300 for a water meter box using a cutter 100 (S100), as shown in FIG. As shown in FIG. 2, sheet metal drawing (S200) is performed so that the edge of the cut front cover body 300 is bent at a right angle using a forming machine 400.

이때 상기 전면커버 본체(300)를 판금 성형하는 단계(S200)는 테두리를 직각으로 굴곡되도록 성형함과 동시에 전면커버 본체(300)에 상부로 복수 개의 보강돌기(도면에 미도시)가 돌출되며, 도 3에 도시된 바와 같이 중앙에 용도 표시 문구(예: 수도계량기함)가 돌출되도록 판금 성형하는 것이 바람직하다.At this time, in the step (S200) of sheet metal forming the front cover main body 300, the edge is formed to be curved at a right angle, and at the same time, a plurality of reinforcing protrusions (not shown in the drawing) protrude upward from the front cover main body 300, As shown in FIG. 3, it is preferable to form sheet metal so that a usage indication text (e.g., water meter box) protrudes in the center.
