Description
본 발명은 표면 처리 및 방수 시트를 이용한 복합식 방수 처리 공법 및 이에 의하여 시공된 방수 구조와 그 조성물에 관한 것으로, 특히 콘크리트 건축 구조물의 옥상, 벽, 바닥, 천정의 누수를 방지하기 위하여 사용되는 표면 처리 및 방수 시트를 이용한 복합식 방수 처리 공법 및 이에 의하여 시공된 방수 구조와 그 조성물에 관한 것이다.
The present invention relates to a composite waterproofing method using a surface treatment and a waterproof sheet, and a waterproof structure and its composition, in particular, the surface treatment used to prevent leakage of roofs, walls, floors, ceilings of concrete building structures And a composite waterproofing method using a waterproof sheet, and a waterproof structure and a composition thereof constructed by the waterproof sheet.
주지하는 바와 같이, 콘크리트 구조물의 옥상이나 지하외벽, 바닥 등의 방수를 위하여 사용되는 방수재는 석유화학계열에서 얻은 고체의 브라운 아스팔트, 아스팔트 컴파운드, 아스팔트 펠트, 아스팔트 루핑을 주성분으로 하여 합성고분자 유기섬유 등으로 만든 방수재가 이용되고 있으며, 이를 이용한 아스팔트 방수공법은 이제까지 수십년간 실시 해오던 방수공법으로서, 이는 반복도포 시공으로 방수층의 도막이 비교적 두꺼워 방수효과가 우수하고 유성이므로 동절기 작업이 가능한 장점이 있는 반면에, 아스팔트는 열공법이므로 좁은 장소나 밀폐된 장소에서 시공이 불가할 뿐만 아니라, 루핑 이음 부위에 누수가 발생될 가능성이 높고, 겹층 시공이므로 공정이 복잡하며, 특별한 시공 기술이 요구되어 인건비가 많이 들고, 작업의 위험도가 높으며, 환경 공해문제가 심각하고, 온도의 변화에 민감하여 균열이 생기기 쉬울 뿐만 아니라 하자 발생시 보수가 불가능하며, 우기철 공사기간을 감안하면 공기가 길어지는 단점이 있었다.As is well known, the waterproofing material used for waterproofing the roof of the concrete structure, the basement outer wall, the floor, etc. is composed of solid brown asphalt, asphalt compound, asphalt felt, asphalt roofing, etc. Waterproofing materials are used, and the asphalt waterproofing method has been carried out for decades. This is a repetitive coating, the coating of the waterproofing layer is relatively thick, so the waterproof effect is excellent and oily, so it is possible to work in winter. As asphalt is a thermal method, it is not only possible to install it in a narrow place or a closed place, but also it is highly likely to leak water on the roofing joint, and because it is a layered construction, the process is complicated, and special construction technology is required, resulting in high labor costs. , The risk of working In addition, the environmental pollution problem is serious, and it is susceptible to cracking due to the change in temperature, and it is impossible to repair it in case of a fault.
또 다른 방수재로는 천(Cloth) 혹은 P.P부직포를 중심자재로 하여 합성고분자 화합물과 아스팔트를 혼합하여 고무화 아스팔트를 접착 성형시킨 롤(Roll)형태의 시트방수제가 제공되고 있으며, 이는 시공이 간단하여 공기단축의 효과가 있고 신축성이 좋아 모체의 균열 대응성이 좋으며, 동절기 시공이 가능하고 작업이 간단하고 안전한 반면에, 이음부위가 많아 이음부위 하자 발생시 하자부위 발견이 어렵고 보수비가 많이 들며, 시공은 간단하나 정밀시공을 요하고, 외부작업시 일정한 공간이 필요할 뿐만 아니라, 옹벽방수 시공 시 내부에 액체방수 시공이 병행되어야 하는 단점이 있으며, 별도의 보호층을 시공하여야 하는 문제점이 있는 것이다.As another waterproofing material, a sheet waterproofing agent in the form of a roll in which a rubber or asphalt is adhesively formed by mixing a synthetic polymer compound and asphalt using a cloth or a PP nonwoven fabric as a center material is provided. It has the effect of shortening of air and good elasticity, so it is good to cope with cracks of the mother, it is possible to install in winter, and the operation is simple and safe.However, due to the large number of joints, defects are difficult to find and costly to repair. It is simple but requires precise construction, as well as a certain space is required for external work, there is a disadvantage that the liquid waterproofing must be parallel to the inside when the retaining wall waterproofing, there is a problem that a separate protective layer should be constructed.
또한, 유기 고분자 재료인 폴리우레탄 수지와 정제 타르(Tar)를 혼합한 탄성 고무성의 유연성 도막 형성으로 된 도막 방수재에 의한 타르 우레탄 방수공법이 이용되고 있으나, 이는 콘크리트 균열에 강하고 이음부위가 없어 소지의 균열 또는 진동에 잘 견디어 방수효과가 우수하고, 하자 발견이 용이하고, 보수가 간편한 장점이 있는 반면에, 시공비가 비싸고 방수재의 주재와 경화제가 구분되어 있으므로 시공주의를 요하며, 유기화합물이므로 시공시 작업자에 유해하고, 화재의 염려가 있는 문제점이 있다.In addition, a tar urethane waterproofing method using a coating waterproof material made of an elastic rubber-like flexible coating film in which an organic polymer material, a polyurethane resin, and refined tar is mixed is used, but it is resistant to concrete cracks and has no joints. Excellent resistance to cracks and vibrations, excellent waterproofing effect, easy to find defects, easy to repair, while high construction cost, and requires the precautions of construction because the main material and the curing agent of the waterproofing material is separated, it is an organic compound Harmful to workers, there is a problem that there is a risk of fire.
또 다른 방수재로 벤토나이트시트 시트를 활용하고 있으나, 기존의 벤토나이트시트는 점착성이 없어 콘크리트면에 부착하는데 어려움이 있으며 또한 고정을 하였다 하더라도 배관 등에 감아 사용할 경우에는 접착고정이 불가하여 초기 누수가 발생 우려가 높게 되고 특히 물과 접촉 시 벤토나이트가 흡윤 팽창하면서 방수를 유지할 수 있게 되나 장기간 물과 접촉 시 접착력이 저하되어 분리됨으로써 크랙부분에 흡윤 팽창력이 없어지므로 방수효과를 잃게 되는 문제점이 있었다.
Bentonite sheet sheet is used as another waterproofing material. However, the existing bentonite sheet is difficult to attach to the concrete surface because it is not sticky, and even if it is fixed, it is impossible to fix the adhesive when it is wound around pipes. In particular, the bentonite is able to maintain the waterproofing when the bentonite is inflated by contact with water, but the adhesive force decreases when contacted with water for a long time.
본 발명의 목적은 이러한 문제점을 해결하기 위하여 처리 대상 콘크리트 구조물 표면에 1차 도포제 조성물을 도포하여 콘크리트 표면에 침투시킴으로써 표면을 강화하고 하지 접착력을 높이며, 이에 방수시트와의 완전 접착을 위한 2차 도포제 조성물을 도포하고 그 위에 자착력 및 점착력을 갖는 방수시트를 부착하여 공정을 단순화하면서도 항구적인 방수처리가 가능하며, 소음방지, 단열효과까지 얻을 수 있도록 한 표면 처리 및 방수 시트를 이용한 복합식 방수 처리 공법 및 이에 의하여 시공된 방수 구조와 그 조성물을 제공함에 있다.
