Description

배관 이음새 누수 감지방법 및 그 배관 연결구조{A water leakage detection method and pipe connecting structure of pipe laying}A water leakage detection method and pipe connecting structure of pipe laying

본 발명은 건축물 시공시 벽체 또는 바닥에 매설되는 배관의 누수 여부를 점검하기 위한 것으로, 배관의 이음새 부분에서 발생되는 미세한 누수를 육안으로 쉽게 확인할 수 있도록 한 누수 감지방법 및 배관 연결구조에 관한 것이다.The present invention relates to a leak detection method and a pipe connection structure for checking the leakage of pipes buried in the wall or floor during construction of the building, so that it is easy to visually check the minute leaks generated in the seam of the pipe.

일반적으로 상수도 배관이나 보일러 배관과 같이 벽체 또는 바닥에 매설되어지는 배관은 여러 개의 파이프를 설계에 따라 서로 연결하여 벽체 또는 바닥면에 포설하는 것으로, 배관이 포설된 상태에서 콘크리트를 타설하기 전에 배관의 연결상태를 점검하고 배관 및 배관 이음새의 누수 여부 등을 검사하는 검측과정을 거치게 된다.In general, pipes buried in the wall or floor, such as water supply pipes or boiler pipes, are connected to each other according to the design and laid on the wall or floor, and before the concrete is laid while the pipe is laid, It checks the connection and inspects the pipe and the joint for leaks.

이때, 배관 이음새의 누수 여부를 검사하는 방법으로는 누수를 탐지하는 기계장비를 이용한 방법과 배관에 물을 채운 후 일정 시간동안 수압을 걸어 이음새 부분에서 누수가 발생하는지 육안으로 관찰하여 누수부위를 판단하는 육안검사로 나뉘어지는데, 소형 건축물에서는 기계장비를 활용하는 방법은 장소가 협소한 환경여건과 비용상의 문제로 인하여 실질적으로 거의 사용되지 않고 육안검사가 주로 사용되어진다.At this time, as a method of checking the leakage of the pipe joint, the method using a mechanical equipment for detecting the leak and filling the pipe with water for a certain period of time, and visually observing whether the leak occurs in the joint portion to determine the leakage site In small buildings, the method of utilizing mechanical equipment is practically rarely used due to the narrow environment and cost, and the visual inspection is mainly used.

하지만, 이러한 육안검사의 문제가 누수량이 많은 경우 외부에서 쉽게 식별가능하지만, 누수량이 극미량인 경우 육안으로 누수여부를 확인하기가 어렵고, 특히 배관 이음새는 밸브 또는 배관연결 유니온으로 배관이 연결되어 있어서 미세한 양의 누수는 확인하기가 더욱 어렵다는 문제가 있다.However, this problem of visual inspection can be easily identified from the outside when the leakage is large, but it is difficult to check the leakage by the naked eye when the leakage is very small, especially the pipe seam is fine because the pipe is connected by a valve or a pipe connection union. Positive leaks are more difficult to identify.

또한, 설치장소의 환경이나 기후에 따라 실내가 건조한 경우 누수되는 물의 양보다 증발되는 양이 많으면 아무리 관찰을 한다 하더라도 누수포인트를 찾을 수 없고, 따라서 실질적으로 누수가 되고 있음에도 불구하고 이러한 극미량의 누수는 확인하지 못한 상태로 바닥을 타설하게 된다.In addition, if the room is dried according to the environment or climate of the installation site, if the amount of evaporation is larger than the amount of water leaked, no leakage point can be found, no matter how observed, and therefore, even though the water leakage is practically, such a small amount of leakage The floor is poured without confirmation.

따라서 이러한 것이 하자발생의 요인이 될 뿐만 아니라, 이렇게 적은 양이라도 장기간 계속적으로 누수가 발생하게 되면 물이 증발하지 못하고 타설되어진 콘크리트로 스며들어 누수량이 쌓이면서 결국에는 건축물의 벽체 또는 바닥에서 누수가 발생하는 문제가 발생되는 것이다.Therefore, this is not only a cause of defects, but even if such a small amount continuously leaks for a long time, water does not evaporate, seeps into the poured concrete, and leaks accumulate and eventually leaks from walls or floors of buildings. Problems arise.

특히, 이러한 매설형 공법은 배관이 콘크리트 속에 매립되어 있어 추후에는 누수포인트를 찾기가 어렵고, 벽체 또는 바닥을 뜯어내고 보수작업을 하여야 하므로 작업의 어려움은 물론 많은 유지보수비용이 발생하게 되는 것이다.In particular, this buried construction method is difficult to find the leak point in the future because the pipe is embedded in the concrete, the wall or floor must be torn off and repair work, as well as a lot of maintenance costs will occur.

따라서 본 발명은 누수 감지 방법을 개선하여 저렴한 비용으로 소형 건축물에서도 간단하게 실시할 수 있으면서도 정밀하게 관찰하지 않고도 육안으로 쉽게 누수 여부를 감지하여 하자발생률을 줄이도록 한 것이다.Therefore, the present invention is to improve the leak detection method to reduce the defect occurrence rate by easily detecting the leakage with the naked eye without being able to perform a precise observation even in a small building at low cost.

이를 위하여 본 발명은 배관을 포설한 후 이음새 부분에 점검테이프를 접착하거나 또는 이음새 직하방의 바닥면에 점검테이프를 깔거나 또는 배관 이음새에 장착되는 밸브 또는 배관연결 유니온에 자체적으로 점검테이프를 부착하여 배관이 포설된 상태에서 배관에 수압을 걸어 이음새 부분의 누수여부를 육안으로 쉽게 확인할 수 있도록 한 것이다.To this end, the present invention is to install the pipe and then attach the check tape to the seam or to the bottom of the seam directly below the tape or to attach the check tape to the valve or pipe connection union mounted on the pipe joint itself to the pipe In this laid state, water pressure was applied to the pipe so that it was easy to visually check the leakage of the seam.

또한, 이때 상기 점검테이프는 극미량의 수분침투에도 반응하는 변색시트를 사용하고, 변색시트의 구조는 수분흡수가 용이한 종이 또는 부직포로 된 색지의 일면에 수분에 잘 분해되는 코팅층을 형성하여 수분흡수에 의하여 코팅층이 분해되면서 색지가 노출되면서 극미량의 누수 여부까지 육안으로 쉽게 확인할 수 있도록 한 것이다.In this case, the inspection tape uses a discoloration sheet that reacts to a very small amount of water penetration, and the structure of the discoloration sheet forms a coating layer that decomposes well in moisture on one surface of colored paper made of paper or nonwoven fabric, which absorbs moisture. As the coating layer is decomposed by the color paper is exposed, it is easy to visually check whether or not a very small amount of leakage.

따라서 본 발명은 육안으로 쉽게 누수여부를 감지할 수 있어 간단하게 누수검사를 시행할 수 있고, 따라서 짧은 시간에 전체 배관 이음새를 점검할 수 있어 검측시간을 단축할 수 있는 것이다.Therefore, the present invention can easily detect whether or not the leakage can be performed with the naked eye, it is possible to perform a simple leak inspection, and thus it is possible to check the entire pipe seam in a short time can shorten the detection time.

또한, 극미량의 누수까지 감지할 수 있으므로 누수로 인한 시공상의 하자발생률을 줄일 수 있으며 이에 따라 건축물을 장기간 사용시에도 누수로 인한 유지관리 비용이 절감되는 것이다.In addition, it is possible to detect a very small amount of water leakage, thereby reducing the construction failure rate due to water leakage, thereby reducing the maintenance costs due to water leakage even when the building is used for a long time.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

상수도 배관이나 보일러 배관은 벽체나 바닥면 등에 매립되는 형태로 시공되는 구조로써, 건축물을 축조하는 과정에서 건물의 뼈대를 구성하는 철근골조 및 외부 벽체 등을 설치한 후 상수도 라인이나 보일러 배관라인을 따라서 배관을 포설하고, 포설되어진 부분을 콘크리트를 타설하여 마감하게 되는데, 그 콘크리트 타설 전에 배관의 연결상태 점검 및 누수여부를 확인하는 검침과정을 거치게 되는 것으로, 본 발명은 이러한 배관의 검측과정에서 변색에 의한 점검테이프(40)(40)를 이용함으로써 배관 이음새의 누수여부를 육안으로 쉽게 확인할 수 있도록 한 것이다.Water supply pipes or boiler pipes are constructed in the form of being embedded in walls or floors.In the process of constructing a building, reinforcing steel frames and external walls are formed along the water supply line or boiler pipe line. The pipe is laid, and the laid part is finished by pouring concrete. The concrete is inspected before the concrete is connected to the pipe and the inspection process is checked to see if there is a leak. By using the check tape (40) and (40) by means of the naked eye can easily check whether the leakage of the pipe joint.

즉, 도 1에 도시된 바와 같이 본 발명은 복수의 배관(10)을 밸브(20) 및 배관연결 유니온을 이용하여 시공되는 상수도 및 보일러 배관라인의 누수여부를 점검방법에 있어서, 복수의 배관(10)을 밸브(20)와 배관연결 유니온(30)을 이용하여 배관라인(1)으로 연결하는 단계와, 수분에 의하여 변색되는 점검테이프(40)를 배관(10)과 배관연결 유니온(30)의 연결 단부에 접착하는 단계와, 연결된 배관라인(1)에 물을 주입하여 일정시간 동안 배관 내부에 수압을 발생시키는 단계와, 배관 이음새에 접착된 점검테이프(40)의 변색 여부를 관찰하는 단계를 거쳐 누수 검사를 하도록 한 것이다.That is, as shown in Figure 1 the present invention is a plurality of pipes (10) by using the valve 20 and the pipe connection union in the method of checking whether or not the leakage of water and boiler pipe line, a plurality of pipes ( 10) connecting the valve 20 and the pipe connection union 30 to the pipe line 1, and the check tape 40 discolored by moisture, the pipe 10 and the pipe connection union (30). Adhering to the connection end of the step, injecting water into the connected pipe line (1) to generate water pressure inside the pipe for a predetermined time, and to observe the discoloration of the check tape (40) adhered to the pipe joint Leak test is to go through.

이때, 배관의 연결구조는 도 4 및 도 5와 같이 밸브(20) 또는 배관연결 유니온(30)의 연결부(21,31)에 배관이 접속되어 배관라인(1)이 이루어진 상태에서 배관(10)이 밸브(20) 또는 배관연결 유니온(30)의 연결부(21,31)에 삽입되어 노출된 배관(10)의 외주연에는 연결부(21,31)의 외측 단부와 밀착되어지게 수분에 의하여 변색되는 점검테이프(40)를 접착하는 것이고, 배관(10)에 접착된 점검테이프(40)의 변색여부에 의하여 배관라인(1)의 누수여부를 육안으로 쉽게 확인할 수 있게 되는 것이다.At this time, the pipe connecting structure is a pipe 10 in a state in which the pipe is connected to the connecting portions 21 and 31 of the valve 20 or the pipe connecting union 30 as shown in FIGS. 4 and 5. The outer periphery of the pipe 10 inserted and inserted into the connection portions 21 and 31 of the valve 20 or the pipe connection union 30 is discolored by moisture to be in close contact with the outer ends of the connection portions 21 and 31. It is to bond the check tape 40, it is possible to easily check whether the leakage of the pipe line (1) by the discoloration of the check tape 40 adhered to the pipe (10).

따라서 간단하게 누수검사를 시행할 수 있을 뿐만 아니라, 전체 배관라인(1)의 이음새를 상세하게 관찰할 필요없이 짧은 시간에 전체 배관 이음새를 점검할 수 있으며, 극미량의 누수까지도 변색에 의하여 쉽게 감지할 수 있어 누수로 인한 하자발생을 방지할 수 있게 되는 것이다.Therefore, not only can a leak test be performed, but the whole pipe joint can be inspected in a short time without having to observe the seams of the entire pipe line in detail, and even a small amount of leak can be easily detected by discoloration. It is possible to prevent the occurrence of defects due to leakage.

이때, 상기 점검테이프(40)는 도 6에 도시된 바와 같이 수분흡수가 용이한 종이 또는 부직포로 된 색지(41)의 일면에 수분에 분해되는 코팅층(42)을 형성하면 점검테이프(40)에 미세한 수분이 흡수될 경우에도 코팅층(42)이 분해되면서 색지(41)가 노출되어 점검테이프(40)의 변색여부를 육안으로 쉽게 확인할 수 있도록 되는 것으로, 이때 코팅층(42)은 수분에 반응하는 정도를 조절함으로써 점검테이프(40)의 변색감응도를 조절할 수 있게 되는 것이고, 가장 바람직하게는 공기중의 습도에 의하여 쉽게 분해되지 않을 정도이면서도 점검테이프(40)의 직접적인 수분침투에 의하여는 극미량인 경우에도 쉽게 분해되는 정도로 코팅층(42)의 수분 반응도를 설정함이 바람직한 것이다.At this time, the inspection tape 40 is formed on the inspection tape 40 when the coating layer 42 is decomposed to moisture on one surface of the colored paper 41 made of paper or nonwoven fabric which is easily absorbed as shown in FIG. 6. Even when minute water is absorbed, the coating layer 42 is decomposed and the colored paper 41 is exposed so that the discoloration of the check tape 40 can be easily checked with the naked eye. In this case, the coating layer 42 reacts with moisture. It is possible to adjust the discoloration sensitivity of the check tape 40 by adjusting the, most preferably even if the amount is not easily decomposed by the humidity in the air, even if the trace amount by the direct moisture penetration of the check tape 40 It is desirable to set the moisture reactivity of the coating layer 42 to the extent that it is easily decomposed.

그리고 코팅층(42)이 형성된 색지(41)의 이면에는 접착층(43)과 이형지(44)를 형성하면 별도의 접착수단이 없이도 점검테이프(40)에서 이형지(44)를 제거한 후 접착층(43)을 이용하여 배관에 간단하게 접착할 수 있게 되는 것이다.If the adhesive layer 43 and the release paper 44 are formed on the back surface of the colored paper 41 on which the coating layer 42 is formed, the adhesive layer 43 is removed after removing the release paper 44 from the check tape 40 without a separate adhesive means. It can be easily adhered to the pipe by using.

한편, 배관라인(1)의 점검방법에 있어서 배관(10)의 외주면에 점검테이프(40)를 접착하는 것을 배관라인(1)의 이음새 직하방에 깔아 배치하여도 배관 이음새의 누수여부를 점검할 수 있는 것으로, 도 2와 같이 복수의 배관(10)을 밸브(20)와 배관연결 유니온(30)을 이용하여 배관라인(1)으로 연결하는 단계와, 수분에 의하여 변색되는 점검테이프(40)를 연결된 배관라인(1)의 이음새 직 하방에 깔아 배치하는 단계와, 연결된 배관라인(1)에 물을 주입하여 일정시간 동안 배관 내부에 수압을 발생시키는 단계와, 배관 이음새의 직하방에 위치한 점검테이프(40)의 변색 여부를 관찰하는 단계를 거쳐 누수 검사가 이루어지도록 할 수 있는 것이다.On the other hand, in the inspection method of the piping line 1, even if it arrange | positions the adhesive tape 40 to the outer peripheral surface of the piping 10 directly under the joint of the piping line 1, it can check whether the piping seam leaks. As shown in FIG. 2, the plurality of pipes 10 are connected to the pipe line 1 using the valve 20 and the pipe connection union 30, and the inspection tape 40 discolored by moisture. Laying the pipe directly below the seam of the connected pipe line (1), and injecting water into the connected pipe line (1) to generate water pressure inside the pipe for a predetermined time, and checking the pipe directly below the seam. Through the step of observing the discoloration of the tape 40 can be made to check the leak.

다만, 이 경우 배관라인(1)의 이음새에서 누수된 물이 낙하된 경우에만 점검테이프(40)의 변색여부를 판단할 수 있으므로, 배관(10)의 외주면에 점검테이프(40)를 접착하여 점검토록 함이 바람직한 것이다.In this case, however, it is possible to determine whether the inspection tape 40 is discolored only when the water leaked from the seam of the piping line 1, so that the inspection tape 40 is attached to the outer circumferential surface of the piping 10 for inspection. This is desirable.

또한, 배관라인(1)의 연결구조에 있어서 밸브(20) 또는 배관연결 유니온(30)의 연결부(21,31)에 수분에 의하여 변색되는 점검테이프(40)를 일체로 형성하고, 배관(10)이 연결부(21,31)에 삽입되어 결합된 상태에서 점검테이프(40)가 외부로 노출되도록 함으로써, 배관라인(1)의 누수여부를 밸브(20) 또는 배관연결 유이온(30)의 연결부(21,31)에 형성된 점검테이프(40)의 변색여부에 의하여 식별할 수 있도록 할 수 있는 것으로, 이때, 배관라인의 누수여부 점검 방법은 도 3과 같이 수분에 의하여 변색되는 점검테이프(40)를 밸브(20) 또는 배관연결 유니온(30)의 연결부(21,31)에 접착하는 단계와, 접착된 밸브(20) 또는 배관연결 유니온(30)을 이용하여 복수의 배관(10)을 배관라인(1)으로 연결하는 단계와, 연결된 배관라인(1)에 물을 주입하여 일정시간 동안 배관 내부에 수압을 발생시키는 단계와, 밸브(20) 또는 배관연결 유니온(30)의 연결부(21,31)에 접착된 점검테이프(40)의 변색 여부를 관찰하는 단계를 거쳐 누수 검사가 이루어지게 되는 것이다.In addition, in the connecting structure of the pipe line 1, the check tape 40 which is discolored by moisture is integrally formed on the connecting portion 21, 31 of the valve 20 or the pipe connecting union 30, and the pipe 10 ) Is inserted into the connecting portions (21, 31) to expose the check tape (40) to the outside, the leakage of the pipe line (1) whether the valve 20 or the connecting portion of the pipe connection ions 30 It can be identified by the discoloration of the check tape (40) formed on the (21, 31), in this case, the leak check method of the pipe line is a check tape (40) discolored by moisture as shown in FIG. To the connection portions 21 and 31 of the valve 20 or the pipe connection union 30, and the plurality of pipes 10 are connected to the pipe line using the bonded valve 20 or the pipe connection union 30. (1) the step, and inject water into the connected pipe line (1) to the water pressure inside the pipe for a certain time The leak test is performed through the step of generating and observing whether the check tape 40 adhered to the connecting portions 21 and 31 of the valve 20 or the pipe connection union 30 is discolored.
