Description

복합방수시트를 이용한 방수 시공방법{Waterproof Construction Method Using Complex Waterproof Sheet}Waterproof Construction Method Using Complex Waterproof Sheet}

본 발명은 건물의 방수 시공방법에 관한 것으로, 더욱 상세하게는 건물의 옥상에 복합방수시트를 이용하여 방수 시공하는 방법에 관한 것이다.The present invention relates to a waterproof construction method of a building, and more particularly, to a method of waterproof construction using a composite waterproof sheet on the roof of a building.

일반적으로 건물은 매년 반복되는 하절기와 동절기를 거치면서 온도 변화에 따른 침투수의 동결이나 부식 또는 대기나 햇빛에 의한 변질 등이 발생하게 된다. 따라서 건물은 외부로부터 노출된 습기와 열 차단을 위한 방수 공사가 필수적이다.In general, buildings undergo freezing or corrosion of infiltrating water due to temperature changes, or deterioration due to air or sunlight as they go through summer and winter that are repeated every year. Therefore, waterproofing work is essential for the building to block moisture and heat exposed from the outside.

또한, 건물의 유지 보수에 따른 방수공사는 기존의 방수층을 제거한 후 보수해야 하고, 액체 방수는 침투수가 표층으로부터 대략 1~3mm까지 투수되어 동결 상태에서 해빙을 반복하는 과정에서 침투수의 투수 깊이만큼 건물 외부가 부식되므로 녹이나 부식 부분을 제거한 후 공사해야 한다.In addition, waterproofing work according to the maintenance of the building must be repaired after removing the existing waterproofing layer, and for liquid waterproofing, the permeated water is permeated from the surface to approximately 1~3mm, and in the process of repeating thawing in a frozen state, the permeation depth of the permeated water is Since the outside of the building is corroded, it must be constructed after removing rust or corrosion.

따라서 방수공사는 건물의 구성 부분, 구성 재료나 방수제에 따라 아스팔트 방수공법, 시트 방수공법, 도막 방수공법, 우레탄 방수공법과 더불어 이들을 선택적으로 조합한 복합 방수공법 등이 상황에 맞게 적용되고 있다.Therefore, as for the waterproofing construction, depending on the constituent parts of the building, the constituent material or waterproofing agent, the asphalt waterproofing method, the sheet waterproofing method, the coating waterproofing method, the urethane waterproofing method, as well as the composite waterproofing method that selectively combines these are applied according to the situation.

아스팔트 방수공법은 가장 오랫동안 사용되어 온 것으로, 방수성은 있으나 아스팔트유의 흐름 방지를 위하여 모래 또는 시트지를 사용하고 열을 가하는 복잡한 공정을 거치게 되므로 시공이 복잡하고 불편하며 시공비가 많이 소요되는 문제가 있다.The asphalt waterproofing method has been used for the longest time, and although it is waterproof, there is a problem that construction is complicated and inconvenient and requires a lot of construction cost because it undergoes a complicated process of applying heat and using sand or sheet paper to prevent the flow of asphalt oil.

시트 방수공법은 합성고무 등을 일정 두께와 폭을 갖도록 시트로 제조하여 시공 현장에서 방수면에 접착시켜 방수층을 형성하는 것이다. 시트의 제조 때에 다양한 적층 구조를 통해 필요한 물성 구현이 용이하고, 시공이 편리한 장점은 있으나, 복잡한 부분에 시공이 어렵고, 시트들 사이 이음매에서의 수밀성이 떨어지며, 수밀을 위한 수작업이 필요한 문제가 있다.The sheet waterproofing method is to form a waterproof layer by making a sheet of synthetic rubber and the like to have a certain thickness and width, and bonding it to the waterproof surface at the construction site. There is a problem in that it is easy to implement the necessary physical properties through a variety of laminated structures in the manufacture of the sheet, and is convenient to construct, but it is difficult to construct in a complex part, the watertightness at the joint between the sheets is poor, and manual work for watertightness is required.

도막 방수공법은 주로 에폭시, 우레탄, 아크릴 수지 또는 아스팔트를 주재료로 사용하되, 여기에 희석제로 유기용제가 혼합된다. 그러나 VOC, 포름알데히드와 같은 휘발성 유기용제가 사용되어 인체에 유해하고, 심한 냄새가 나며, 환경 친화적이지 못하고, 가연성이어서 위험한 문제가 있다.The coating waterproofing method mainly uses epoxy, urethane, acrylic resin or asphalt as the main material, but an organic solvent is mixed with it as a diluent. However, since volatile organic solvents such as VOC and formaldehyde are used, they are harmful to the human body, have a severe odor, are not environmentally friendly, and are flammable, so there is a dangerous problem.

우레탄 방수공법은 시공할 부분의 바닥을 정리하고, 여기에 프라이머를 도포하여 충분히 침투시켜 건조한 후, 바닥면에 액상우레탄수지를 도포하여 우레탄 도막을 형성함으로써 방수 효과를 얻는 것이다. 콘크리트면과 접착이 잘 되고, 신축성이 우수하여 균열 때에 어느 정도 방수성을 유지할 수 있는 장점은 있으나, 바닥면에 밀착시키는 공법이어서 균열이 발생하면 근본적인 해결이 곤란하고, 심한 온도변화, 콘크리트의 수분 증발, 바닥 콘크리트의 균열 발생 때에 부풀음 현상이 발생하거나 시공된 우레탄 도막이 손상될 수 있고, 연속적으로 들뜨는 현상이 발생되어 건물의 방수성과 내구성이 저하되는 문제가 있다.In the urethane waterproofing method, a waterproof effect is obtained by arranging the floor of the part to be constructed, applying a primer thereto, sufficiently penetrating and drying it, and then forming a urethane coating film by applying a liquid urethane resin to the floor. It adheres well to the concrete surface and is excellent in elasticity, so it has the advantage of maintaining waterproofness to some extent when cracking, but it is a method that adheres to the floor, so it is difficult to fundamentally solve when cracks occur, severe temperature change, and moisture evaporation of concrete. , There is a problem in that swelling may occur when cracks in the floor concrete occur or the urethane coating applied may be damaged, and a phenomenon of continuous excitation may occur, thereby deteriorating the waterproofness and durability of the building.

이와 관련된 선행기술로서, 특허문헌1은 물, 분산제, 합성수지, 산화철, 경량 세라믹, 견운모, 증점제를 순차적으로 넣고 교반시키면서 1액형 탄성 차열방수제를 제조함으로써, 3~5℃ 정도의 보온 효과가 있고, 공기가 잘 통하며, 물이 차단됨과 더불어 냄새가 없고, 곰팡이가 발생하지 않는 탄성 차열방수제의 조성물과 그 제조 방법이 개시되어 있다. 그러나 상기 특허문헌1은 방수성능은 어느 정도 있으나, 내부식성과 내구성이 떨어지고, 차열 및 단열 성능이 좋지 않기 때문에 외부 열기의 건물 내부 유입과 내부 열기의 건물 외부 유출이 용이하여 에너지가 낭비되어 냉난방 효율이 저하되며, 도시에서의 열섬 효과가 심화되는 문제가 있다.As a prior art related to this, Patent Document 1 has a thermal insulation effect of about 3 to 5°C by sequentially adding water, a dispersant, synthetic resin, iron oxide, lightweight ceramic, sericite, and a thickener to prepare a one-component elastic heat shielding and waterproofing agent while stirring, Disclosed are a composition of an elastic heat shielding and waterproofing agent that passes through air well, has no odor, and does not generate mold, as well as blocking water and a method of manufacturing the same. However, Patent Document 1 has some waterproof performance, but it has poor corrosion resistance and durability, and poor heat shielding and insulation performance, so it is easy for external heat to flow into the building and to outflow of internal heat to the outside of the building, thereby wasting energy and cooling and heating efficiency. This decreases, and there is a problem that the heat island effect in the city is intensified.

또한, 건축물의 지붕 및 바닥 재료로 콘크리트, 금속, 아스팔트 싱글, 기와, 슬레이트 등 매우 다양한 재료를 사용한다. 이런 재료들의 수명과 방수 성능을 확보하여 건축물을 장기적인 내구성을 확보하기 위해서는 열과 습기를 제어할 수 있어야 한다.In addition, a wide variety of materials such as concrete, metal, asphalt shingle, tile, and slate are used as roof and floor materials for buildings. In order to ensure long-term durability of a building by securing the life and waterproof performance of these materials, it is necessary to control heat and moisture.

종래 콘크리트 바닥의 마감처리방법은 콘크리트 바닥의 표면에 아무런 마감처리를 하지 않은 노출 상태로 유지시키거나, 표면을 연마하여 갈아내고 매끄럽게 만든 다음 소정의 보강용 광택제를 도포한 후 재차 연마하는 방법을 이용하거나 또는 기능성 도포제를 바닥의 표면에 도포하는 방법을 이용하였다.The conventional method of finishing concrete floors is to maintain the surface of the concrete floor in an exposed state without any finishing treatment, or to polish the surface to grind and make it smooth, and then apply a predetermined reinforcing polish and then polish again. Or, a method of applying a functional coating agent to the surface of the floor was used.

현재, 바닥에 기능성 도포제인 표면강화제를 시공하여 건물 바닥의 표면을 강화시키는 방법은 기본적인 강화제 이외에 단열성, 방수성, 내열성, 난연성, 내화학성 및 내후성 등의 기능을 갖춘 강화제의 발달로 다양한 방법이 제시되고 있다.Currently, various methods are proposed to strengthen the surface of a building floor by applying a surface strengthening agent, a functional coating agent on the floor, in addition to the basic strengthening agent, with the development of a strengthening agent with functions such as insulation, waterproofing, heat resistance, flame resistance, chemical resistance and weather resistance. have.

특허문헌2는 천연석 무늬형성 도료 조성물에 관한 것으로서, 1차 조성물, 2차 조성물, 조막형성조제, 증점제, 방부제, 분산제 및 소포제가 혼합되어 조성된 천연석 무늬형성 도료 조성물이고, 상기 1차 조성물은 아크릴수지에멀션, 물, 80∼140메시의 천연규사, 체질안료 및 착색제로 조성되며, 상기 2차 조성물은 아크릴수지에멀션, 물, 80∼140메시의 천연규사 및 유리섬유로 조성되는 천연석 무늬형성 도료 조성물이 공개되어 있다. 상기 특허문헌2는 바닥의 표면에 천연석의 무늬를 부여할 수 있는 효과를 실현하였으나, 단열성, 방수성, 내열성, 난연성, 내화학성 및 내후성 등 기능성이 다소 미약한 문제가 제시되고 있는 실정이다.Patent Document 2 relates to a natural stone pattern-forming coating composition, and is a natural stone pattern-forming coating composition composed by mixing a primary composition, a secondary composition, a film forming aid, a thickener, a preservative, a dispersant, and an antifoaming agent, and the primary composition is acrylic Consisting of resin emulsion, water, natural silica sand of 80 to 140 mesh, extender pigment and colorant, the secondary composition is a natural stone pattern forming paint composition composed of acrylic resin emulsion, water, natural silica sand of 80 to 140 mesh and glass fiber Has been released. Patent Document 2 has realized the effect of imparting a natural stone pattern on the surface of the floor, but a problem of somewhat weak functionality such as heat insulation, waterproofness, heat resistance, flame retardancy, chemical resistance and weather resistance is presented.

또한 특허문헌3은 우수한 내오염성 및 탄성을 갖는 수성도료용 조성물이 개시되어 있고, 특허문헌4는 건물 단열용 수성도료 조성물에 관한 사항이 공개되어 있다. 그러나 이러한 도료는 방수성능이 우수하지 못하고, 내구성 등에서도 뛰어난 성능을 보여주지 못한다.In addition, Patent Document 3 discloses a composition for a water-based paint having excellent stain resistance and elasticity, and Patent Document 4 discloses a matter related to a water-based paint composition for building insulation. However, these paints do not have excellent waterproof performance and do not show excellent performance in durability.

현재 우리나라에서도 일부 건축물 지붕 방수를 위해 차열 및 반사 성능을 활용한 도막 방수공법이 사용되고 있기는 하나, 이는 방수제 상부에 기능성 코팅제를 추가로 도포하여 보완한 개념이다.Currently, even in Korea, a coating waterproofing method that utilizes heat shielding and reflective performance is being used to waterproof some building roofs, but this is a concept supplemented by additionally applying a functional coating on the waterproofing agent.

그리고 우레탄 방수제는 수증기 투과성이 없어 계절에 따라 온도차가 큰 지역에서는 건물소재의 열에 의한 팽창수축이 크고, 또한, 내부 및 외부의 화학작용에 의해 방수성능을 장기적으로 유지하는데 한계가 있으며, 이는 지속적인 내구성을 확보하기 어려운 실정이다.In addition, urethane waterproofing agents do not have moisture vapor permeability, so expansion and contraction due to heat of building materials are large in regions with large temperature differences depending on the season, and there is a limit to maintaining the waterproofing performance for a long time due to internal and external chemical reactions. It is difficult to secure.
