Description

경질시트를 이용한 도막 방수공법 및 그 방수시트Coating film waterproofing method using hard sheet and its waterproof sheet

본 발명은 건축물의 콘크리이트 바탕층 표면에 수분의 침투를 차단하기 위하여 시공되는 경질시트를 이용한 도막방수공법 및 그 방수시트에 관한 것이다.The present invention relates to a waterproof coating method and a waterproof film using a hard sheet that is constructed to block the penetration of moisture on the surface of the concrete base layer of the building.

통상 강수량이나 온·습도 및 바람 등의 기상조건이 변화무쌍한 지역에 축조된 건축물은 기상조건에 의해 수분이 실외로부터 실내로 침투하게될 요인이 다분히 존재하게 되므로, 수분의 침투를 차단하여야 함이 당연한 과제인바, 이의 해결책으로 다음과 같은 다양한 방법의 방수공법이 개발되기에 이르렀다.In general, buildings constructed in areas with varying weather conditions such as precipitation, temperature, humidity, and wind have a lot of factors that allow moisture to penetrate into the room from the outside due to the weather conditions. As a task, the solution has led to the development of various waterproofing methods such as:

첫째, 건축물의 바탕층 표면에 용융 아스팔트를 도포하는 공법이 있으나, 이는 높은 온도로 가열·용융케 되므로 안전사고의 위험과 함께 불쾌한 냄새 및 유독성 물질에 의해 작업자가 해를 입을 우려가 있고, 시공 후 남는 폐자재가 환경오염을 유발하였으며, 조건에 따라 용융 아스팔트의 온도를 달리하여야 함에도 불구하고 온도관리가 어려워 시공상태가 고르지 못하게 됨은 물론, 우기 시에는 시공이 불가능하여 공사기간을 장기화하게 되는 등의 문제점이 있다.First, there is a method of applying molten asphalt to the surface of the base layer of the building, but since it is heated and melted to a high temperature, there is a risk of safety accidents and workers may be harmed by unpleasant smells and toxic substances. The remaining waste materials caused environmental pollution, and although the temperature of the molten asphalt was to be changed according to the conditions, the temperature was difficult to manage, resulting in uneven construction and prolonged construction period due to the impossible construction during the rainy season. There is a problem.

둘째, 건축물의 바탕층 표면에 우레탄을 도포하는 공법이 있으나, 이는 화학적으로 정확한 배합비를 유지해야 하므로 반드시 시공을 숙련공에 의존해야 하고, 시공중 경화가 진행됨으로써 점도가 높아지게 되면 지속적으로 희석제를 혼가하게 되어 물성을 저하시키게 됨과 더불어 희석제에 의한 인화 및 폭발의 위험과 유독성 피해를 감수해야 하였으며, 바탕층의 평활도가 떨어질 경우 도막의 두께를 균일하게 유지하기가 어려움은 물론 자체 물성상 통기성이 없어 수증기압에 의한 도막 박리뿐만 아니라 바탕층의 콘크리이트(모르터) 자체의 함수로 도막 접착이 어려워 들뜨게 됨으로써 파단의 원인이 되는 등의 문제점이 있다.Second, there is a method of applying urethane to the surface of the base layer of the building, but this must be maintained in a chemically accurate compounding ratio, the construction must rely on skilled workers, and as the viscosity increases due to the hardening during construction, the diluent is continuously mixed. As a result, the physical properties were lowered, and the risk of ignition and explosion due to diluents and toxic damages were to be taken. Not only the peeling of the coating film but also the adhesion of the coating film as a function of the concrete (mortar) itself of the base layer becomes difficult, causing problems such as causing breakage.

셋째, 건축물의 바탕층 표면에 연질시트를 접착제로 접착 시공하는 공법이 있으나, 이는 이음매 부분의 밀봉이 어려워 누수의 우려가 내재됨과 아울러 시공이 까다롭고, 접착된 시트의 표면에 누름층을 시공케 됨에 따라 시공이 복잡함과 함께 누름층의 균열에 의해 시트가 쉽게 파열되어 누수의 원인이 되는 등의 문제점이 있을뿐만 아니라, 보수시 공사 규모가 커져 경제적 손실이 크고, 발생되는 폐자재를 폐기처리케 됨에 따른 환경오염의 문제가 있다.Third, there is a method of bonding soft sheet to the surface of the base layer of the building with adhesive, but it is difficult to seal the seam part, which is inherently leaky and difficult to construct, and the pressing layer is applied to the surface of the bonded sheet. As the construction is complicated and the sheet is easily broken by the crack of the pressing layer, it causes problems such as water leakage.In addition, the scale of construction during construction is large, resulting in high economic loss and disposal of the generated waste materials. There is a problem of environmental pollution.

상기와 같은 종래의 방수공법은 시공시와 보수시 모두 바탕층을 고르게 하는 평탄 작업을 전처리 공정으로 수행해야 함은 물론, 현장에서 직접 시공해야만 하는바, 본 발명은 이와같은 종래 방수공법의 난제를 해소하고자 내균열저항성과 인장강도 등의 재질적 특성이 우수한 경질시트를 이용하여 현장에서 직접 시공할 수 있도록 함은 물론, 경질시트를 이용하여 단위 규격화한 방수시트를 사전에 구비한 후 이를 현장에서 간단히 시공할 수 있도록 함으로써, 공사기간을 단축하고 바탕층의 균열로부터 발생하는 방수층의 하자요인을 완전히 일소하며 외관 또는 미려한 고품질의 방수층을 얻고자 한 것이다.The conventional waterproofing method as described above should be carried out in the pre-treatment process, as well as to perform a flat work to even the base layer during construction and repair, the present invention is to solve the challenges of such a conventional waterproofing method In order to solve the problem, it is possible to construct directly in the field by using a hard sheet having excellent material properties such as crack resistance and tensile strength. In addition, after the unit standardized waterproof sheet is prepared in advance, By simplifying the construction, it is intended to shorten the construction period, completely eliminate the defects of the waterproof layer resulting from the cracking of the base layer, and to obtain a waterproof or beautiful high quality waterproof layer.

도 1a는 본 발명에 따른 방수공법의 공정도이고, 도 2 내지 도 5는 본 발명에 따른 공법으로 시공된 방수층의 각부 단면도로서, 건물의 바탕층(1) 표면에 합성수지 또는 합성비닐 등의 재질로 되는 방습포(2)를 포설하되, 바탕층(1)의 표면이 과다하게 불균일 할 경우 층고르기 공정이 선행되어야 하고 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 according to the present invention, Figures 2 to 5 are cross-sectional views of each part of the waterproof layer constructed by the method according to the invention, the base layer (1) of the building base material (1) surface of the synthetic resin or synthetic vinyl material If the surface of the base layer (1) is excessively non-uniform, the layer leveling process should be preceded. If necessary, the surface of the base layer (1) should be subjected to a water inclination gradient process and then the surface thereof. A moisture barrier (2) is placed in the container.

방습포(2)의 상층에 바탕층(1)의 규격 및 형태를 감안하여 절단한 금속재 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.Lay the metal hard sheet 3 cut in consideration of the size and shape of the base layer 1 on the upper layer of the moisture-proof cloth 2, but the joints of each hard sheet 3 to face or overlap, 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 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 corner portion (see FIG. 4) where the raised portion 1 ′ is generated at the edge of the base layer 1, that is, the inward corner portion 1a ′ is bent inward so that the hard sheet 3 is ∠45 °. And the upper sheet, that is, the outward corner portion 1b 'is spaced apart from the outward corner portion 1b' so as to have a clearance gap 8 and outwardly bent, and the hard sheet 3 at a position close to the raised portion 1 '. By bending to form a stretchable portion 9 of the loop shape.

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 the 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 경질시트(3)를 포설할 수도 있다.And, if heat insulation is required in view of the function and use of the building to be constructed waterproof layer, as shown in Figure 6, after the installation process of the moisture-proof fabric (2) laminated the heat insulating material 11 and a hard sheet ( 3) can be installed.

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 경질시트(3)의 표면에 도막방수재를 도포하여 도막방수층(4)을 형성하되, 연부에 소정폭 만큼 방수재를 도포하지 않은 미처리부(5')가 형성되도록 방수시트(5)를 자동화 설비를 갖춘 공장 등지에서 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 수 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. The coating film waterproofing material is formed on the surface of the hard sheet 3 cut in consideration of the size and shape of the base layer 1 of the building to be constructed, thereby forming the coating film waterproofing layer 4, but the waterproofing material is not applied to the edges by a predetermined width. After manufacturing the waterproof sheet 5 in advance in a factory equipped with an automation facility so that the untreated portion 5 'is formed, the waterproof sheet 5 is prepared by a process as shown in FIG. Install the damp-proof fabric 2 on the top, install the waterproof sheet 5 on the upper layer, install the nonwoven fabric 6 'on the untreated portion 5' and tape the tape 6 on the surface thereof, Coating water-resistant on only the surface of the tape (6) We can finish construction of waterproofing layer quickly.

이와같은 본 발명은, 전술한 바와같이 시공코져 하는 현장의 조건에 따라 모든 공정을 현장에서 직접 수행하는 일반 공법과 공장 등지에서 경질시트(3)에 도막방수층(4)을 미리 형성시켜 단위 규격화한 방수시트(5)를 현장으로 운반하여 후속 공정만으로 시공을 수행토록 한 건식공법 및 일반공법과 건식공법을 혼합한 반건식공법으로 방수층을 시공할 수 있게 되는바, 어떠한 공법으로 시공하더라도 경질시트(3)는 방습포(2)나 단열재(11)상에 단순 적층된 상태이어서 바탕층(1)으로 부터 수분이 증발할 경우 이들 사이의 미세한 간극을 통해 방수층의 연부로 배출되므로 건물 자체가 발생하는 수분은 외부로 무리없이 방출시킴은 물론 경질시트(3)의 탄성이 평활도를 유지하게 되므로 바탕층(1)의 표면이 불균일 하더라도 바탕층 고르기 공정을 생략할 수 있음과 동시에 도막방수층(4)의 훼손을 방지하여 수명을 장기화 할 수 있게 됨과 더불어 도포 또는 접착식 공법을 채택한 종래의 방수층과는 달리 보수작업 또한 간편·용이함을 제공하게 된다.As described above, according to the present invention, a unit standardization is performed in which the coating layer waterproof layer 4 is formed on the hard sheet 3 in advance in a general method and a factory where all processes are performed directly according to the conditions of the construction site. By carrying the waterproof sheet (5) to the site and carrying out the construction only by the subsequent process, the waterproof layer can be constructed by the dry method and the semi-dry method that mixes the general method and the dry method. ) Is simply stacked on the moisture-proof cloth (2) or the heat insulating material (11), when the water evaporates from the base layer (1) is discharged to the edge of the waterproof layer through a minute gap between them, the moisture generated by the building itself Since the elasticity of the hard sheet 3 maintains the smoothness as well as the release to the outside without difficulty, even if the surface of the base layer 1 is uneven, it is possible to omit the base layer selection process. At the same time, it is possible to prolong the service life by preventing damage to the coating waterproof layer 4 and at the same time, unlike the conventional waterproof layer adopting the coating or adhesive method, the repair work is also simple and easy to provide.

한편, 각 경질시트(3)의 연부가 만나게 되는 이음부는 도 3a 내지 도 3c에 도시한 바와같이 맞대기 이음과 겹치기 이음방법을 선택시공할 수가 있게 되는데, 온도변화가 심한 곳이나 방수층 표면을 활용하여야 하는 용도를 갖는 곳에서는 고정못(7)을 이용하여 경질시트(3)의 연부를 바탕층(1)에 관통 고정함으로써 신축 및 유동에 의한 방수층의 훼손을 방지하게 되고, 도 4에 도시한 바와같이 건물의 가장자리 등에 발생하는 치켜올림부위(1')같은 모서리부의 내향모서리부(1a')에는 경질시트(3)를 ∠45°정도가 되도록 면접기 처리를 함과 동시에 외향모서리부(1b')와의 사이에 여유간극(8)을 형성함으로써 기후조건에 따라 경질시트(3)가 유연히 신축되도록 하여 훼손을 방지토록 하며, 치켜올림부위(1')와 근접되는 평활면 측에는 루우프 형태의 신축부(9)를 형성함으로써, 온도변화시 경질시트(3)가 신축되더라도 신축부(9)가 그 길이를 보정토록 하여 방수층에 주름이나 균열 등의 결함이 발생되는 것을 방지하게 된다.On the other hand, the joints where the edges of each hard sheet 3 meet can be selected and overlapped butt joint method as shown in Figs. 3a to 3c, the temperature change is severe or the surface of the waterproof layer should be utilized Where there is a purpose to use the fixing nail (7) to penetrate the edge of the hard sheet 3 through the base layer (1) to prevent damage to the waterproof layer by stretching and flow, as shown in FIG. Likewise, the inward corner portion 1a 'such as the raised portion 1', which occurs at the edge of the building, is subjected to an interview treatment so that the hard sheet 3 is about 45 ° and the outward edge portion 1b '. By forming a clearance gap (8) between the) and the rigid sheet (3) to flexibly stretch and contract according to the climatic conditions to prevent damage, and to the surface of the smooth surface close to the lifting portion (1 ') of the loop-shaped stretch portion Mold 9 Thereby, by the elastic ever even if the suspending member (9) rigid sheet (3) when a temperature change is corrected its length will prevent the defects such as wrinkles and cracking of the waterproof layer.

그리고, 시공이 완료된 후에는 도 7에 도시한 바와같이 도막방수층(4)의 표면에 미려한 색상을 갖는 방수성 코팅재를 도포 함으로써 코팅층(10)을 형성할 수도 있는바, 이 경우 방수층의 성능을 더욱 강화할 수 있음은 물론 건물의 외관을 미려하게 하는 효과를 제공케 된다.In addition, after the construction is completed, as shown in FIG. 7, the coating layer 10 may be formed by applying a waterproof coating material having a beautiful color to the surface of the coating waterproof layer 4, in which case the performance of the waterproof layer may be further enhanced.
