일반적으로, 벽, 슬라브 등과 같은 방화 구획체를 관통하는 배관은 방화 구획체에 형성된 관통공에 배관을 삽입한 후, 배관과 관통공 사이의 공간을 내화 충전제로 메워서 시공된다. 내화 충전제로는 그라스울, 내화몰탈, 실리콘, 우레탄 등이 사용될 수 있다.In general, a pipe that penetrates a fire compartment such as a wall, a slab, or the like is constructed by inserting a pipe into a through hole formed in the fire compartment, and then filling a space between the pipe and the through hole with a refractory filler. As the refractory filler, glass wool, refractory mortar, silicone, urethane, or the like may be used.

그러나, 배관을 관통공에 삽입한 후, 별도로 내화 충전제를 이용하여 배관과 관통공 사이의 공간을 메워야 하기 때문에 작업이 복잡하고 시간이 많이 소요된다는 문제점이 있다.However, after inserting the pipe into the through-holes, the space between the pipes and the through-holes must be filled separately using a refractory filler, which causes a complicated and time-consuming problem.

또한, 상기 내화 충전제를 이용하여 배관과 관통공 사이의 공간을 완전히 메우는 것이 어렵기 때문에 소음 및 열 손실 등의 문제가 발생하고, 화재시 매연이 이동하는 통로가 되기도 한다. 특히, 배관이 플라스틱으로 된 경우에는 화재시 열로 인하여 배관이 녹게 되고, 배관이 녹게 되면 배관을 통하여 화염과 매연이 이동하게 된다는 문제점이 있다.In addition, since it is difficult to completely fill the space between the pipe and the through-hole by using the refractory filler, problems such as noise and heat loss occur, and it may be a passage through which smoke moves during a fire. In particular, when the pipe is made of plastic, the pipe melts due to heat during fire, and when the pipe melts, there is a problem in that flame and soot move through the pipe.

이하, 첨부된 도면을 참조로 하여 본 발명의 실시예들을 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예에 따른 충진과 팽창을 위한 시트를 보여주는 단면도이다.1 is a cross-sectional view showing a sheet for filling and expansion according to a preferred embodiment of the present invention.

도면을 참조하면, 상기 시트(100)는 팽창성 내화시트(10)와, 팽창성 내화시트(10)의 상부에 적층된 팽창성 폼 부재(20)를 구비한다.Referring to the drawings, the sheet 100 includes an expandable fire resistant sheet 10 and an expandable foam member 20 laminated on the expandable fire resistant sheet 10.

팽창성 내화시트(10)는, 알려진 바와 같이, 화재시에 열이 가해지면 팽창하는 내화시트이다.The expandable fire resistant sheet 10 is, as is known, a fire resistant sheet which expands when heat is applied in a fire.

팽창성 폼 부재(20)는 불연처리된 불연성이고, 작용하던 가압력 예를 들어, 포장이 제거되면 팽창하는 성질을 가진다. 팽창성 폼 부재(20)는 배관(도 3의 1)이 관통공(3)에 삽입된 후, 팽창하여 배관(1)과 관통공(3) 사이의 공간을 밀폐한다. 따라서, 배관(1)과 관통공(3) 사이의 실링(sealing)이 불충분하여 화재시에 매연이 확산되는 것을 방지할 수 있다.The expandable foam member 20 is nonflammable, nonflammable, and has the property of expanding when the applied pressing force, for example, the packaging, is removed. The expandable foam member 20 is expanded after the pipe (1 in FIG. 3) is inserted into the through hole 3 and expands to seal the space between the pipe 1 and the through hole 3. Therefore, the sealing between the pipe 1 and the through hole 3 is insufficient, and it is possible to prevent the soot from being diffused at the time of fire.

바람직하게, 팽창성 폼 부재(20)는 작용하던 가압력이 제거되면 10분 내지 60 분 사이에 팽창하는 폴리올레핀(PO)계 또는 폴리올레핀(PO)계를 포함하는 오픈 셀 폼(open cell foam)이거나, 작용하던 가압력이 제거되면 10분 내지 60 분 사이에 팽창하는 실리콘(Silicon)계 또는 실리콘(Silicon)계를 포함하는 오픈 셀 폼(open cell foam)이다.Preferably, the expandable foam member 20 is an open cell foam comprising a polyolefin (PO) or polyolefin (PO) system that expands between 10 minutes and 60 minutes when the applied pressing force is removed.

상기 시트(100)는 관통공(3)의 직경, 배관(1)의 직경이나 크기, 요구되는 단열의 정도, 요구되는 불연성의 정도 등에 따라 팽창성 폼 부재(20)를 더 구비하거나 비팽창성 폼 부재를 더 구비할 수도 있다.The sheet 100 further includes an expandable foam member 20 or a non-expandable foam member according to the diameter of the through hole 3, the diameter or size of the pipe 1, the required degree of thermal insulation, the required degree of incombustibility, and the like. It may be further provided.

도 2에 나타난 바와 같이, 시트(100a)는 팽창성 폼 부재(20)의 상부에 적층된 비팽창성 폼 부재(30)를 더 구비할 수도 있다. 비팽창성 폼 부재(30)는 불연처리된 불연성이고, 바람직하게는 폴리올레핀(PO)계 또는 폴리올레핀(PO)계를 포함하는 크로스 셀 폼(Close cell foam) 또는 폴리올레핀(PO)계를 포함하는 비발포성 시트(Sheet)이거나, 실리콘(Silicon)계 또는 실리콘(Silicon)계를 포함하는 크로스 셀 폼(Close cell foam) 또는 실리콘(Silicon)계를 포함하는 비발포성 시트(Sheet)이다.As shown in FIG. 2, the sheet 100a may further include a non-expandable foam member 30 stacked on top of the expandable foam member 20. The non-expandable foam member 30 is nonflammable, non-flammable, and preferably non-foamable, including a cross cell foam or polyolefin (PO) system including polyolefin (PO) or polyolefin (PO) system. The sheet may be a sheet, or a non-foamable sheet including a silicon-based or a silicon-based cross-cell foam or a silicon-based system.

한편, 비팽창성 폼 부재(30)는 팽창성 폼 부재(20)와 팽창성 내화시트(10) 사이에 게재되도록 설치될 수도 있다.On the other hand, the non-expandable foam member 30 may be installed to be placed between the expandable foam member 20 and the expandable fire resistant sheet (10).

또한, 팽창성 폼 부재(20)의 상부에 팽창성 내화시트(10)가 적층될 수도 있다. 즉, 배관(1) 둘레에 팽창성 폼 부재(20)가 감겨지고 팽창성 폼 부재(20)의 상부에 팽창성 내화시트(10)가 감겨질 수도 있다.In addition, the expandable fire resistant sheet 10 may be laminated on the expandable foam member 20. That is, the expandable foam member 20 may be wound around the pipe 1 and the expandable fireproof sheet 10 may be wound on the upper portion of the expandable foam member 20.

아울러, 팽창성 내화시트(10)와, 팽창성 폼 부재(20) 및, 비팽창성 폼 부재(30)의 적층과정에는 수용성 바인더 - 예를 들면, 우레탄, 아크릴 및 기타 수용 성 접착제 등 - 또는, 고분자 접착제를 사용할 수 있다.In addition, in the lamination process of the expandable fire resistant sheet 10, the expandable foam member 20, and the non-expandable foam member 30, a water-soluble binder-for example, urethane, acrylic and other water-soluble adhesives, or the like-or a polymer adhesive Can be used.

그러면, 본 발명의 바람직한 실시예에 따른 충진과 팽창을 위한 시트(100)를 이용하여 배관(1)을 시공하는 과정을 설명하기로 한다.Then, the process of constructing the pipe 1 using the seat 100 for filling and expansion according to the preferred embodiment of the present invention will be described.

먼저, 시트(100)를 이용하여 배관(1)을 감싼다. 시트(1)의 두께 또는 감싸는 횟수는 배관(1)과 관통공(3)의 직경과 요구되는 단열의 정도 등을 고려하여 정할 수 있다. First, the pipe 1 is wrapped using the sheet 100. The thickness of the sheet 1 or the number of wrappings may be determined in consideration of the diameter of the pipe 1 and the through hole 3 and the required degree of thermal insulation.

시트(100)를 이용하여 배관(1)을 감싼 후에는, 도 3에 나타난 바와 같이, 배관(1)을 관통공(3)에 삽입한다. 시트(100)의 팽창성 폼 부재(20)는 작용하던 가압력 예를 들면, 포장이 제거되면, 도 4에 나타난 바와 같이, 대략 10-60분 후에 팽창하여 배관(1)과 관통공(3) 사이의 공간을 밀폐한다.After the pipe 1 is wrapped using the sheet 100, the pipe 1 is inserted into the through hole 3 as shown in FIG. 3. The expandable foam member 20 of the seat 100 expands after approximately 10-60 minutes, as shown in FIG. 4, when the applied pressure, for example, the packaging, is removed, between the pipe 1 and the through hole 3. Seal the space.

이와 같이, 본 발명은 시트(100)를 이용하여 배관(1)을 둘러싼 후 배관(1)을 관통공(3)에 삽입하기만 하면 되고 배관(1)과 관통공(3) 사이의 공간을 밀폐하기 위하여 별도로 내화 충진제를 사용하지 않아도 되기 때문에 작업이 매우 간편해진다.As described above, the present invention only needs to insert the pipe 1 into the through hole 3 after enclosing the pipe 1 using the sheet 100, thereby providing a space between the pipe 1 and the through hole 3. The operation is very simple because it does not require a separate refractory filler to seal.

또한, 관통공(3)은 대체로 그 내주면의 요철이 심한데, 팽창성 폼 부재(20)는 팽창하면서 관통공(3)의 내주면에 밀착될 수 있기 때문에 소음 차단, 단열 등에 있어서 우수하다는 장점이 있다.In addition, the through hole 3 is generally a roughness of the inner circumferential surface, the expandable foam member 20 can be in close contact with the inner circumferential surface of the through hole 3 while expanding, there is an advantage in that it is excellent in noise isolation, heat insulation and the like.

한편, 도 5 및 도 6은 화재시에 시트(100)가 관통공(3) 또는 배관(1)을 밀폐하는 것을 보여주는 단면도이다.5 and 6 are cross-sectional views illustrating that the sheet 100 seals the through hole 3 or the pipe 1 during a fire.

전술한 바와 같이, 팽창성 내화시트(10)는 열을 받으면 팽창한다. 따라서, 화재시에 플라스틱 등으로 된 배관(1)이 녹을 경우에는 팽창하여 배관(1) 또는 관통공(3)을 막는다. 팽창성 내화시트(10)가 팽창하여 배관(1) 또는 관통공(3)을 막음으로써 화염 또는 매연이 배관(1) 또는 관통공(3)을 통하여 확산되는 것을 방지할 수 있다.As described above, the expandable fire resistant sheet 10 expands when subjected to heat. Therefore, when the pipe 1 made of plastic or the like melts during a fire, it expands to block the pipe 1 or the through hole 3. By expanding the expandable fire resistant sheet 10 to block the pipe 1 or the through hole 3, it is possible to prevent the flame or soot from spreading through the pipe 1 or the through hole 3.

본 발명에 따른 충진과 팽창을 위한 시트 및, 이를 이용하는 방화 구획체 관통공에서 배관을 설치하는 공법은 다음과 같은 효과를 가진다.The seat for filling and expansion according to the present invention, and the method of installing the pipe in the fire protection partition through-hole using the same has the following effects.

첫째, 배관과 관통공 사이의 공간을 용이하게 밀폐시킬 수 있다.First, the space between the pipe and the through hole can be easily sealed.

둘째, 화재시에 화염과 매연이 관통공을 통하여 이동되는 것을 차단할 수 있다.Second, the fire and smoke can be blocked from moving through the through-hole in the event of fire.
