수도계량기함용 전면커버의 제조방법{MANUFACTURING METHOD OF FRONT COVER FOR WATER METER BOX}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 for manufacturing a front cover for a water meter box, and more particularly, an opening and closing door is provided in the center of the front cover so that it can be easily attached to and detached from the inspection window of the front cover, and the water meter can be easily installed through the inspection window. can be read or inspected, and the opening and closing door on the inspection window of the front cover is sealed to maintain airtightness to prevent foreign substances from entering the inside of the water meter box. Inflow into the interior can be prevented, and an insulator is attached to the back of the front cover and opening/closing door to keep the water meter box warm to prevent freezing and bursting of the water meter in winter, and the manufacturing process of the front cover and opening/closing door is simple. It relates to a method for manufacturing a front cover for a water meter box capable of improving productivity by doing so.

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, tap water is used as drinking water and water in all homes or businesses, and the tap water is supplied to each home or business through a water supply pipe, and a water meter is installed to automatically measure the supply amount of the tap water.

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, when the temperature of the tap water supplied through the water supply pipe as described above drops sharply in the cold winter season, it freezes inside the water supply pipe or the water meter and increases in volume, thereby causing the water pipe or the water meter to freeze. There was a problem.

종래에는 동절기에 동파현상을 방지하기 위하여 수도관과 수도계량기를 모두 지하에 매설하는 방식을 이용되고 있다,Conventionally, in order to prevent freezing and bursting in winter, a method of burying both water pipes and water meters underground has been used.

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, in apartment houses such as townhouses, villas, and apartments, which are becoming more common today, water pipes are buried inside concrete walls, whereas water meters are installed to be buried inside the wall because the manager must check the supply of tap water from time to time, but observe it from the outside. It is installed in a state 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 a wall surface, and a front cover is coupled to the front surface of the water meter box embedded in the wall surface, and the front cover is installed so that a meter reader can check or read the water meter. A door that can be opened and closed is coupled.

그러나 종래의 수도계량기함은 외부의 충격에 의해 도어가 굴곡되거나 파손되면 전면커버로부터 도어를 열기 불편한 문제점이 있었다.However, when the door of the conventional water meter box is bent or damaged by an external impact, it is inconvenient to open the door from the front cover.

그리고 상기 도어와 전면커버의 사이가 완전히 밀폐되지 않아 동절기에 찬공기가 전면커버와 도어 사이를 통해 수도계량기함 내부로 유입되어 수도관 또는 수도계량기가 동파되는 문제점이 있었다.In addition, since the space between the door and the front cover is not completely sealed, cold air is introduced into the water meter box through the gap between the front cover and the door in winter, and the water pipe or water meter freezes.

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 houses, even though most of the above water meter boxes are installed, in case of a cold wave in winter, as an emergency measure, the outside of the water meter box is covered with newspaper or a thick box to insulate it. There was a problem in that freezing and bursting occurred in water pipes or water meters.

또한 상기와 같은 종래의 수도계량기함용 전면커버와 도어는 그 제조공정이 복잡하여 생산성이 떨어지고, 제조단가가 상승하게 되는 문제점이 있었다.In addition, the conventional front cover and door for a water meter box have a problem in that the manufacturing process is complicated, so productivity is lowered and manufacturing cost is increased.

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 reference to the accompanying drawings.

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.As shown in FIG. 1, in the manufacturing method of the front cover for a water meter box according to the present invention, a stainless plate 200 is cut into the size of the front cover body 300 for a water meter box using a cutter 100 (S100), As shown in FIG. 2, sheet metal is formed (S200) so that the edge of the cut front cover body 300 is bent at a right angle using a molding 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 sheet metal forming step (S200) of the front cover body 300, the edge is formed to be bent 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 body 300, As shown in FIG. 3, it is preferable to form a sheet metal so that a usage indication phrase (eg, water meter box) protrudes from the center.

그리고 상기와 같이 전면커버 본체(300)를 판금 성형한 후 도 4에 도시된 바와 같이 절단기를 이용하여 개폐도어(600)의 크기로 상기 판금성형된 전면커버 본체(300)의 중앙에 점검창(310)이 형성되도록 전면커버 본체(300)의 중앙을 절단(blanking, S300)한다.In addition, after forming the front cover body 300 in sheet metal as described above, as shown in FIG. 4, an inspection window ( 310) is cut at the center of the front cover body 300 to form (blank, S300).

또한 상기와 같이 전면커버 본체(300)의 중앙을 절단(S300)하면서 동시에 전면커버 본체(300)의 네 모서리에 볼트를 이용하여 전면커버 본체(300)를 수도계량기함(900)의 전면에 결합할 수 있도록 원형 또는 중앙을 향한 대각선 방향으로 타원형의 볼트 체결공(도면에 미도시)을 천공할 수 있다.In addition, while cutting the center of the front cover body 300 as described above (S300), the front cover body 300 is coupled to the front of the water meter box 900 using bolts at the four corners of the front cover body 300 at the same time. It is possible to drill an oval bolt fastening hole (not shown in the drawing) in a circular or diagonal direction toward the center.
