Description
본 발명은 건축물의 콘크리이트 바탕층 표면에 수분의 침투를 차단하기 위하여 시공되는 방수시공용 비금속제 경질 방수시트에 관한 것이다.The present invention relates to a non-metallic hard waterproof sheet for waterproof construction, which is constructed to block the penetration of moisture on the surface of the concrete base layer of a building.
통상 건축물은 강수등 외부의 기상조건에 의해 수분이 실외로부터 실내로 침투하게되는 경우가 많아 외부로부터, 수분의 침투를 차단시켜 주기 위하여 다양한 방법의 방수공법이 개발되어 있다. 그 대표적인 예로서,In general, buildings often infiltrate moisture from the outside into the interior due to weather conditions such as precipitation, and various waterproof methods have been developed to block the penetration of moisture from the outside. As a representative example,
첫째, 건축물의 바탕층 표면에 용융 아스팔트를 도포하는 공법이 있으나, 아스팔트는 높은 온도로 가열·용융하여 사용하여야 하므로 안전사고의 위험과 함께 불쾌한 냄새 및 유독성 물질에 의해 작업자가 해를 입을 우려가 있고, 시공 후 남는 폐자재가 환경오염을 유발하며, 조건에 따라 용융 아스팔트의 온도를 달리하여야 하는데 온도관리가 어려워 시공상태가 고르지 못하게 되는 단점이 있으며, 우기에는 시공이 불가능하게 되는 등의 문제점이 있다.First, there is a method of applying molten asphalt to the surface of the base layer of the building, but the asphalt must be heated and melted at a high temperature so that the worker may be harmed by unpleasant odors and toxic substances with the risk of safety accidents. , The waste materials left after construction cause environmental pollution, and the temperature of the molten asphalt should be changed according to the condition, but there is a disadvantage that the construction state is uneven due to the difficult temperature control, and the construction is impossible during the rainy season. .
둘째, 건축물의 바탕층 표면에 우레탄을 도포하는 공법이 있으나, 이는 화학적으로 정확한 배합비를 유지해야 하므로 시공을 숙련공에 의존해야 하고, 시공중경화가 진행되어 점도가 높아지게 되면 지속적으로 희석제를 혼가하여 사용하여야 하므로 물성을 저하시키게 되며 또한 희석제는 인화 및 폭발의 위험과 유독성 갖고 있어 취급이 어렵고, 바탕층의 평활도가 떨어질 경우 도막의 두께를 균일하게 유지하기가 어려움은 물론 바탕층 콘크리이트(모르터) 자체의 함수로 콘크리트면과의 접착력이 떨어져 들뜨게 됨으로써 파단의 원인이 되는 등의 문제가 있다.Secondly, there is a method of applying urethane to the surface of the base layer of the building, but it must be chemically accurate to maintain the mixing ratio, so construction must be relied on by skilled workers, and as the viscosity increases as the construction progresses, the diluent is continuously mixed and used. As the diluent has a risk of ignition and explosion and is toxic, it is difficult to handle and it is difficult to keep the thickness of the coating uniformly when the smoothness of the base layer drops, as well as the base layer concrete (mortar) itself. There is a problem such that the adhesion to the concrete surface is dropped as a function of, causing it to break, causing breakage.
셋째, 건축물의 바탕층 표면에 연질시트를 접착제로 접착 시공하는 공법이 있으나, 이는 이음매 부분의 밀봉이 어려워 누수의 우려가 있고 아울러 시공이 까다롭고, 접착된 시트의 표면에 누름층을 시공케 됨에 따라 시공이 복잡함과 함께 누름층의 균열에 의해 시트가 쉽게 파열되어 누수의 원인이 되는 등의 문제점이 있다.Third, there is a method of adhesive construction of soft sheet on the surface of the base layer of the building, but this is difficult to seal the joint part, which can lead to leakage and difficult construction, and the pressing layer is installed on the surface of the bonded sheet. Accordingly, there is a problem in that the construction is complicated and the sheet easily ruptures due to cracks in the pressing layer, causing leakage.
상기한 종래 방수공법의 문제점들을 개선 시켜주기 위하여 최근에는 내균열저항성과 인장강도가 우수한 금속제 경질시트의 일측면 방수도막층을 형성하여서 된 방수시트를 이용하는 방수공법이 제안된바 있다. (대한민국 특허 공보 공개번호 1999-0069914호)Recently, in order to improve the problems of the conventional waterproof method, there has been proposed a waterproof method using a waterproof sheet formed by forming a waterproof coating layer on one side of a metal hard sheet having excellent crack resistance and tensile strength. (Korean Patent Publication No. 1999-0069914)
이 방수공법은 시공시 바탕층을 고르게하는 평탄작업을 하여주지 않아도 되고 단위규격화된 방수시트를 사전에 준비할 수 있어 현장에서의 공사 기간을 단축시켜 줄 수 있는 등의 이점은 있으나 경질시트로서 강판(鋼板)등의 금속판을 사용하기 때문에 무게가 무겁고 또한 시공중에는 시공장소에 따라서 방수시트를 부분적으로 변형시켜 주어야 하는 경우가 불가피하게 발생하게 되는데 금속판은 변형이 어려워 옥상에서 시공하기에는 불편이 따른다는 문제가 있다. 건물 옥상에 방수시공을 하는 경우 건물하중에 부담을 주지 않기 위하여는 방수시트의 무게가 가벼울수록 좋다.This waterproof method does not require the flat work to even the base layer during construction, and it is possible to prepare the unit standardized waterproof sheet in advance, which can shorten the construction period in the field. Due to the use of metal plates such as (iii), the weight is heavy and during construction, it is inevitable that the waterproof sheet must be partially deformed, but the metal plate is difficult to be deformed, so it is inconvenient to install on the roof. There is. In the case of waterproofing on the roof of a building, the lighter the weight of the waterproof sheet is, the better the load is.
본 발명은 상기한 경질시트를 이용하는 방수공법(대한민국 특허공보 공개번호 1999-0069914호)의 개량발명에 관한 것이다.The present invention relates to an improved invention of the waterproofing method (Korean Patent Publication No. 1999-0069914) using the hard sheet described above.
본 발명의 목적은 일정한 크기로 규격화한 비금속제 경질시트 일면에 방수도막층을 형성시켜서 된 방수시트를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof sheet formed by forming a waterproof coating layer on one surface of a nonmetallic hard sheet standardized to a certain size.
일정한 크기로 규격화한 경질플라스틱판재나 벤토나이트 판재의 일면에 방수 도막층을 형성시켜서된 방수시트를 이용하여 종래의 금속제 방수시트를 이용하는 방수공법 (대한민국 공개 특허 공보 공개번호 1999-0069914호)에 따라 방수시공을 하여주게 되면 종래의 금속제 경질시트를 이용한 경우 보다 건물에 하중 부담을 줄여 줄수 있으며, 작업현장에서의 변형 가공이 용이하여 편리하게 방수시공을 할수 있게 된다.Waterproofing according to the waterproofing method using a conventional metal waterproof sheet using a waterproof sheet formed by forming a waterproof coating layer on one surface of a rigid plastic sheet or bentonite sheet standardized to a certain size (Korean Patent Publication No. 1999-0069914) The construction can reduce the load burden on the building than when using a conventional metal hard sheet, and it is easy to deform at the work site, so that the waterproof construction can be performed conveniently.

도 1a는 본 발명의 방수시트를 사용하는 방수공법의 공정도이고, 도 2 내지 도 5는 본 발명의 방수시트를 사용하여 시공된 방수층의 각부 단면도이다. 먼저 건물의 바탕층(1) 표면에 합성수지 또는 합성비닐 등의 재질로 되는 방습포(2)를 포설한다. 필요한 경우 바탕층(1) 표면에 물경사 구배 처리공정을 수행한 후 그 표면에 방습포(2)를 포설한다.Figure 1a is a process diagram of the waterproof method using the waterproof sheet of the present invention, Figure 2 to Figure 5 is a cross-sectional view of each part of the waterproof layer constructed using the waterproof sheet of the present invention. First, a moisture-proof cloth 2 made of a material such as synthetic resin or synthetic vinyl is laid on the surface of the base layer 1 of the building. If necessary, after performing the water inclination gradient treatment process on the surface of the base layer (1), the moisture-proof cloth (2) is laid on the surface.
방습포(2)의 상층에 바탕층(1)의 규격 및 형태에 맞추어 절단한 비금속재 경질시트(3)를 포설하되, 각 경질시트(3)의 이음부가 맞대어 지도록 하거나 겹쳐지도록 하여 필요에 따라 선택적으로 고정못(7)을 이용하여 바탕층(1)에 관통·타정한 후 이음부에 부직포(6')를 포설하고 그 표면에 테이프(6)를 테이핑한다.A non-metallic hard sheet 3 cut in accordance with the specification and shape of the base layer 1 is placed on the upper layer of the moisture-proof cloth 2, but the joints of the respective hard sheets 3 are faced or overlapped as necessary. After selectively penetrating and tableting the base layer 1 using the fixing nail 7, a nonwoven fabric 6 'is laid on the joint and the tape 6 is taped on the surface.
이때, 바탕층(1)의 가장자리에 치켜올림부위(1')가 발생하는 모서리부(도 4참조) 즉, 내향모서리부(1a')에는 비금속제 경질시트(3)를 ∠45°가 되도록 내향 절곡하고 상부 즉, 외향모서리부(1b')에는 여유간극(8)을 갖도록 외향모서리부(1b')와 이격시켜 외향 절곡하며, 치켜올림부위(1')와 근접되는 위치의 경질시트(3)를 굴곡시켜 루우프 형태의 신축부(9)가 형성되도록 한다.At this time, the non-metallic hard sheet 3 is placed at an angle of about 45 ° to an edge portion (see FIG. 4), that is, an inward edge portion 1a 'where the raised portion 1' is generated at the edge of the base layer 1. Hard sheet bent inward and bent outwardly at an upper edge, that is, spaced apart from the outward corner portion 1b 'so as to have a clearance gap 8 in the upper portion, that is, the outward edge portion 1b'. 3) is bent to form a stretchable portion 9 in the form of a loop.
다음으로, 각 경질시트(3) 및 테이프(6)의 표면에 통상의 도막방수재를 도포·경화시켜 도막방수층(4)을 형성하여 방수층의 시공을 완료한다.Next, an ordinary coating waterproofing material is applied and cured on the surfaces of each hard sheet 3 and tape 6 to form a coating waterproofing layer 4 to complete the construction of the waterproofing layer.
한편, 도 7에 도시한 바와같이 도막방수층(4)의 표면에는 필요에 따라 코팅재를 도포하여 코팅층(10)을 형성할 수도 있다.Meanwhile, as shown in FIG. 7, a coating material may be applied to the surface of the waterproof layer 4 to form a coating layer 10 as necessary.
그리고, 방수층을 시공코자 하는 건물의 기능 및 용도를 감안하여 단열이 요구될 경우 도 6에 도시한 바와같이, 방습포(2)의 포설공정 후 단열재(11)를 적층하고 그 상층에 비금속제 경질시트(3)를 포설할 수도 있다.In addition, when heat insulation is required in consideration of the function and use of the building to be constructed with a waterproof layer, as shown in FIG. The sheet 3 can also be laid.
이상에서와 같은 방수공법은 주로 기후조건이 좋은 경우나, 공사기간이 충분한 경우 적용할 수 있는 공법인바, 기후조건이 나쁜 경우나 공사기간이 충분치 못한 경우에는 도 8 및 도 9에 도시한 바와같이 시공코자 하는 건물 바탕층(1)의 규격 및 형태를 감안하여 절단한 비금속제 경질시트(3)의 표면에 도막방수재를 도포하여 도막방수층(4)을 형성하고, 이때 연부에 소정폭 만큼 방수재를 도포하지 않은 미처리부(5')가 형성되도록 방수시트(5)를 자동화 설비를 갖춘 공장에서 미리 제조한 후 이러한 방수시트(5)를 도 1b에 도시한 바와같은 공정에 의해, 바탕층(1) 표면에 방습포(2)를 포설하고, 그 상층에 방수시트(5)를 포설하며, 미처리부(5')에 부직포(6')를 포설하고 그 표면에 테이프(6)를 테이핑한 후 이음부상의 테이프(6) 표면에만 도막방수재를 도포·경화시킴으로써 신속하게 방수층의 시공을 완료할 수도 있다.As described above, the waterproofing method is mainly a method that can be applied when the weather conditions are good or when the construction period is sufficient, and when the weather conditions are bad or when the construction period is insufficient, as shown in FIGS. 8 and 9.
