Description
본 발명은 콘크리트 구조물의 방수 도막에 관한 것이다. The present invention relates to a waterproof coating of a concrete structure.
건축물의 지붕, 바닥, 지하 주차장, 건축물의 이음부 등과 같이 수분과 접할 수 있는 부위에는 수분이 내부로 스며드는 것을 방지하기 위하여 구조물의 표면에 불투수성의 방수층을 형성하는 방수 공사가 행해진다. 방수처리 될 부위에 따라, 그리고 철근콘크리트, 경량콘크리트 등의 바탕재료에 따라서, 바탕 상태에 따라, 또는 방수 재료에 따라 그 구조와 시공방법 등에 다소의 차이가 발생한다. 가장 일반적으로 쓰이는 방법은 아스팔트 방수 공법, 시트 방수공법, 도막 방수공법 등이 있으며, 최근에는 이들을 복합하여 조합 적층하는 방법 등 상황에 맞는 복합 방수 공법을 적용하고 있다.Waterproofing works to form impermeable waterproof layer on the surface of the structure in order to prevent moisture from penetrating into the interior of the building, such as the roof, floor, underground parking lot, and joints of buildings. Depending on the part to be waterproofed and depending on the base material such as reinforced concrete and lightweight concrete, there is a slight difference in the structure and the construction method depending on the base state or the waterproof material. The most commonly used methods are asphalt waterproofing, sheet waterproofing, and film waterproofing. Recently, a complex waterproofing method suitable for the situation such as a combination of these and lamination has been applied.
아스팔트 방수 공법은 가장 오랫동안 사용되어온 방법인데, 시공시 불편함이 많아 최근에는 기성화된 아스팔트 시트를 사용하고 있지만, 온도차이로 인해 방수재 도막의 자체 균열이 발생하는 문제점이 여전하다.The asphalt waterproofing method has been used for the longest time. However, since the asphalt sheet has been used recently because of the inconvenience during construction, the self-cracking of the waterproofing coating film still occurs due to the temperature difference.
시트 방수 공법은 합성고무 등을 일정두께와 폭을 갖는 시트상으로 제조하여 시공현장에서 방수면에 접착하여 방수층을 형성하는 공법이다. 이 방법은 시트의 제조시 다양한 적층구조를 통해서 필요한 물성을 구현하기가 쉽고, 시공이 편리한 점이 있으나, 복잡한 부위의 시공이 어렵고, 시트간 이음매에서의 완전 수밀성을 이루기 어려우며, 시트간의 이음매의 밀봉 작업이 수작업으로 일일이 이루어지는 문제가 있다.The sheet waterproofing method is a method in which a synthetic rubber or the like is formed into a sheet having a certain thickness and width and adhered to a waterproof surface at a construction site to form a waterproof layer. Although this method is easy to implement necessary physical properties through various laminated structures in the production of sheets, it is convenient for construction, but it is difficult to construct complex parts, and it is difficult to achieve complete watertightness in the seam between seats, There is a problem that this is done manually.
한편 도막 방수 공법은 소재의 종류에 따라 몇 가지가 있는데, 우레탄 방수 공법이 대표적이다. 우레탄 방수 공법은 시공할 바닥 등을 정리하고, 이에 프라이머를 도포하여 바닥에 충분히 침투시켜 건조한 뒤, 바닥면에 액상 우레탄 수지를 도포하여 우레탄 도막을 형성하여 이를 통해 방수를 하는 방법이다. 이러한 우레탄 방수공법은 비교적 하지 콘크리트 면과의 접착이 잘되고, 신축성이 우수하여 하지 균열에 대해서도 어느 정도의 방수 성능을 유지할 수 있다는 장점이 있다. 뿐만 아니라 협소한 곳이나 복잡한 부위에 시공이 상대적으로 용이하고, 이음매 없는 시공이 가능할 뿐만 아니라 보수가 비교적 용이한 점이 있다. 그러나 바닥면에 전면 밀착하는 공법이므로 하지의 균열에 대한 근본적인 해결이 어렵고, 심한 온도변화, 콘크리트의 수분증발, 바닥 콘크리트의 균열 발생이 크게 일어나면 시트공법에서와 마찬가지로 부풀음 현상이 발생될 수 있으며, 시공된 우레탄 도막이 손상되고, 연속적으로 들뜨게 되는 문제가 있다. 특히 주차장과 같은 곳에서는 반복되는 하중으로 우레탄 도막의 들뜸 현상이 빨리 일어나게 되어 방수 수명이 짧은 문제가 있다. 또한, 작업 현장에서 액상으로 도포되어 흐름성이 좋기 때문에 바닥면의 굴곡으로 인해 도막 두께가 불균일해질 수 있고, 도막의 두께를 충분히 형성하여야 하나 용이하지가 않은 문제가 있다.On the other hand, there are several kinds of coating waterproofing methods depending on the type of materials, such as urethane waterproofing method. The urethane waterproofing method is a method of arranging the floor to be applied, applying the primer thereto, sufficiently penetrating the floor, drying the floor, applying liquid urethane resin to the floor surface, and forming a urethane coating film to waterproof the floor. This urethane waterproofing method is advantageous in that it can be adhered relatively easily to the lower surface of the concrete and has excellent elasticity so that waterproof performance can be maintained to some extent even against cracks in the floor. In addition, it is relatively easy to install in a narrow or complex area, it is possible to construct seamlessly, and it is relatively easy to repair. However, it is difficult to fundamentally solve the cracks in the floor due to the close contact with the floor surface, and when the severe temperature change, water evaporation of the concrete, and cracking of the floor concrete occur largely, the swelling phenomenon may occur as in the sheet construction method. There is a problem that the coated urethane coating is damaged and continuously exposed. Particularly in places such as parking lots, there is a problem that the lifetime of the urethane coating is short due to repetitive loading, resulting in short waterproof life. In addition, since it is applied in liquid form at the work site and flowability is good, the thickness of the coating film may be uneven due to the curvature of the bottom surface, and the thickness of the coating film should be sufficiently formed.
보통은 프라이머 위에 우레탄 방수제를 도포하고, 또 다시 반복 도포하여 요구되는 두께를 형성하는데, 이때, 1차로 우레탄 방수제를 도포하고 그 위에 부직포, 유리섬유 등을 적층하고 다시 우레탄 방수제를 도포하는 형태를 사용하기도 한다. 상기 부직포 등은 우레탄 방수제의 두께 형성 목적과 보강재 목적으로 사용되는데, 이들은 연신성이 좋지 않고 인열강도가 좋지 않아 반복되는 외력에 의해 손상 내지는 찢김이 발생하는 문제점은 아직 극복하지 못하였다. Usually, a urethane waterproofing agent is applied on the primer and repeatedly applied to form a required thickness. In this case, a urethane waterproofing agent is applied first, a nonwoven fabric, glass fiber, etc. are laminated thereon and then a urethane waterproofing agent is applied again It is also said. The nonwoven fabric and the like are used for the purpose of forming the thickness of the urethane waterproofing agent and for the purpose of the reinforcing material. However, they have not yet overcome the problem of damage or tear due to repetitive external force due to poor stretchability and poor tear strength.

여기에서, 상기 복합시트층을 구성하는 부직포는 그 일면 또는 양면에 수지 코팅층이 형성되어 있고, 상기 수지코팅층은 에폭시계 수지, 아크릴계 수지 또는 우레탄계 수지로 이루어진 접착제를 더 포함할 수 있으며, 이로 인해 부직포와 필름간의 접착력 및 복합시트와 제1도막층의 접착력이 향상되어 방수 도막의 내구성이 크게 향상될 수 있는 것이다. Here, the resin coating layer may be formed on one side or both sides of the nonwoven fabric constituting the composite sheet layer, and the resin coating layer may further include an adhesive composed of an epoxy resin, an acrylic resin or a urethane resin, And the adhesion between the composite sheet and the first coating layer can be improved, and the durability of the waterproof coating can be greatly improved.
또, 상기 프라이머층, 제1도막층 및 제2도막층은 폴리우레탄 수지이고, 상기 복합시트층을 형성하는 부직포는 폴리에스테르계 수지인 스펀본드 부직포이고, 필름은 폴리우레탄계 수지 필름인 것이 바람직하다.It is preferable that the primer layer, the first coat layer and the second coat layer are a polyurethane resin, the nonwoven fabric forming the composite sheet layer is a spunbonded nonwoven fabric made of a polyester resin, and the film is a polyurethane resin film .
여기에서, 상기 프라이머층은 1액형 습기 경화형의 폴리우레탄 수지로서 경화후 투명하거나 담황색의 막을 형성하여 소지 강도를 보강 및 부착성을 향상하는 것이 더욱 바람직하다. Here, it is more preferable that the primer layer is a one-pack type moisture-curing polyurethane resin after curing to form a transparent or pale yellow film so as to improve the strength and adhesion of the base resin.
그리고, 상기 복합시트의 표면에는 PET 필름 또는 보호재 코팅층으로 형성된 보호층을 더 포함할 수 있다.The surface of the composite sheet may further include a protective layer formed of a PET film or a protective material coating layer.
