Description

노출형 방수구조 시공방법{Exposure type water proofing construction method}{Exposure type water proofing construction method}

본 발명은 노출형 방수구조 시공방법에 관한 것으로서, 보다 상세하게는 방수효과가 우수할 뿐만 아니라 피시공면의 균열을 자가보수하는 기능도 가지므로 방수성능이 지속적으로 유지되며, 차열특성도 가지는 새로운 구성의 노출형 방수구조 시공공법에 관한 것이다. The present invention relates to a method for constructing an exposed type waterproof structure, and more specifically, it has an excellent waterproof effect, and also has a function of self-repairing a crack in a surface to be installed, so that the waterproof performance is continuously maintained and the thermal insulation characteristic is also new. The construction relates to the construction method of the exposed waterproof structure.

일반적으로 건축물의 옥상부분은 방수성능을 가질 수 있도록 방수처리를 필요로 한다. 방수공법은 크게 노출방수공법과 비노출방수공법으로 나뉘는데, 이중 노출방수공법으로 가장 많이 사용되는 것은 우레탄방수재를 사용한 도막방수공법과 시트를 이용한 시트방수공법이다. In general, the roof portion of a building requires waterproofing to have waterproofing performance. The waterproofing method is largely divided into an exposed waterproofing method and a non-exposed waterproofing method. Among them, the most commonly used waterproofing method is a coating film waterproofing method using a urethane waterproofing material and a sheet waterproofing method using a sheet.

그러나, 종래의 방수공법에 의한 방수구조는 피시공면, 즉 콘크리트면이 반복적인 수축과 팽창에 의해 균열이 발생되는 경우에 이러한 균열을 흡수하지 못하고 방수구조에도 균열 및 들뜸이 발생되어 방수성을 상실하게 된다. However, the waterproof structure according to the conventional waterproofing method does not absorb these cracks when the surface to be constructed, i.e., the concrete surface is cracked by repeated contraction and expansion, and cracks and floats are also generated in the waterproof structure, resulting in loss of waterproofness. Is done.

한편, 하절기에 건축물의 지붕이 태양열을 흡수함에 따라 건축 내부의 온도가 상승되고, 이에 따라 냉방비용이 많이 발생된다. 따라서 실내온도상승에 따른 에너지소비가 증가하고 있는데, 이를 방지하기 위해서는 옥상에 방수성과 더불어 차열성을 부여할 필요가 있다. On the other hand, as the roof of the building absorbs solar heat in the summer, the temperature inside the building rises, and accordingly, the cooling cost is high. Therefore, energy consumption is increasing due to an increase in the indoor temperature. In order to prevent this, it is necessary to impart waterproofness and heat shielding properties to the roof.

대한민국 공개특허 제10-2018-0060477호(2018. 06. 07.)Republic of Korea Patent Publication No. 10-2018-0060477 (2018. 06. 07.)

본 발명은 상기와 같은 점에 착안하여 제안된 것으로서, 서로 다른 특성을 가지는 다층구조를 가지므로 방수성이 우수하며, 최하부층이 유동성을 가지기 때문에 피시공면에 균열이 발생되는 경우에 피시공면의 균열을 메워서 자가보수하는 기능을 가지므로 방수구조가 손상되지 않아 방수성능이 장기간 지속적으로 유지되고 차열특성도 가지는 새로운 구성의 노출형 방수구조 시공방법을 제공하는 것이다.The present invention has been proposed in view of the above points, and has a multi-layer structure having different characteristics, so it is excellent in water resistance, and because the bottom layer has fluidity, when the crack is generated in the surface to be formed, It has a function of self-repairing by filling the cracks, so that the waterproof structure is not damaged and the waterproof performance is maintained for a long period of time and provides a new construction method of the exposed waterproof structure having heat shielding characteristics.

본 발명의 일 특징에 따르면, 겔타입방수제로 이루어져서 피시공면(1) 위에 적층되는 유동성 겔층(12): 상기 유동성 겔층(12) 위에 적층된 아스팔트펠트시트층(14); 상기 아스팔트펠트시트층(14) 위에 적층된 우레탄방수층(20); 및 상기 우레탄방수층(20) 위에 적층된 차열탑코팅층(30);을 포함하는 노출형 방수구조 시공방법이 제공된다.According to an aspect of the present invention, a fluid gel layer 12 made of a gel type water repellent and stacked on the surface 1 to be coated: an asphalt felt sheet layer 14 stacked on the fluid gel layer 12; A urethane waterproof layer 20 laminated on the asphalt felt sheet layer 14; And a heat shield column coating layer 30 laminated on the urethane waterproof layer 20 is provided.

이상과 같은 구성을 가지는 본 발명은 서로 다른 방수성과 물성을 가지는 다층구조를 가지기 때문에 방수성이 우수할 뿐만 아니라, 특히, 하부가 시간이 지나도 경화되지 않고 지속적으로 유동성을 가지는 유동성 겔층으로 이루어져서 피시공면에 균열이 발생되는 경우에 피시공면의 균열을 메워서 자가보수하는 기능을 가지며, 피시공면의 신축에도 대응할 수 있어서 방수구조가 손상되지 않는다. 따라서 우수한 방수특성이 장기간 방수성능이 장기간 지속적으로 유지된다. The present invention having the above configuration has a multi-layer structure having different waterproof properties and physical properties, and thus is not only excellent in waterproof properties, but in particular, the lower part is made of a fluid gel layer that is not cured over time and has fluidity, so that the surface to be coated is formed. It has a function of self-repairing by filling the cracks of the surface to be constructed when cracks are generated in it, and it can cope with the expansion and contraction of the surface of the surface, so the waterproof structure is not damaged. Therefore, excellent waterproof properties and long-term waterproof performance are maintained for a long time.

또한, 최상부를 이루는 차열탑코팅층이 형성되어 차열특성을 가지기 때문에,하절기에 실내온도상승을 억제하며, 이에 따라 실내온도상승에 따른 에너지소비증가를 방지할 수 있어서 에너지절약효과를 얻을 수 있다. In addition, since the thermal barrier coating layer forming the uppermost portion is formed and has thermal barrier properties, it is possible to suppress an increase in indoor temperature during the summer season, thereby preventing an increase in energy consumption due to an increase in indoor temperature, thereby obtaining an energy saving effect.

도 1은 본 발명의 바람직한 실시에 따른 방수구조의 단면도이다.1 is a cross-sectional view of a waterproof structure according to a preferred embodiment of the present invention.

이하에서, 본 발명을 실시예를 통해 좀 더 구체적으로 설명한다. Hereinafter, the present invention will be described in more detail through examples.

도 1은 본 발명의 바람직한 실시예에 따른 방수구조의 단면도로서, 본 발명은 다음과 같은 방법으로 시공된다. 1 is a cross-sectional view of a waterproof structure according to a preferred embodiment of the present invention, the present invention is constructed in the following way.

1) 피시공면(2)을 전처리하는 단계1) Pre-treatment of the surface to be processed (2)

피시공면(2), 즉, 옥상 바닥면의 이물질을 제거하고, 요철부분, 균열부분 등을 충진하여 피시공면(2)을 평탄화시킨다. 그리고 피시공면이 젖은 경우에는 피시공면을 건조시킨다. The object surface 2, that is, the foreign material on the roof top surface is removed, and the uneven part and the crack part are filled to flatten the surface 2. Then, when the surface is wet, the surface is dried.

2) 피시공면(1)에 복합방수시트(10)를 적층시키는 단계2) Laminating the composite waterproof sheet 10 on the surface to be coated 1

복합방수시트(10)는 아스팔트펠트시트층(14)의 저면에 유동성 겔층(12)이 형성되어 이루어진다.Composite waterproof sheet 10 is made of a fluid gel layer 12 is formed on the bottom surface of the asphalt felt sheet layer (14).

상기 아스팔트펠트시트층(14)은 폴리에스테르 등과 같은 합성수지 펠트시트, 즉, 부직포에 아스팔트를 함침시킨 시트로서, 내구성과 방수성이 우수한 장점을 가진다. The asphalt felt sheet layer 14 is a synthetic resin felt sheet such as polyester, that is, a sheet impregnated with asphalt in a nonwoven fabric, and has an advantage of excellent durability and waterproofness.

그리고 상기 유동성 겔층(12)은 아스팔트펠트시트층(14)의 저면에 겔타입 방수제를 도포하여 형성된다. 겔타입 방수제로는 공지된 것 중에서 적당한 것을 선택하여 사용한다. And the fluid gel layer 12 is formed by applying a gel type waterproofing agent to the bottom surface of the asphalt felt sheet layer 14. As a gel type waterproofing agent, a suitable one is selected from known ones and used.

이러한 유동성 겔층(12) 유동성을 가지기 때문에 피시공면에 균열이 발생되면 균열내부로 유입되어 균열을 메우게 되는데, 특히, 시간이 지나도 경화되지 않고 유동성이 지속되기 때문에 유동성 겔층(12)이 피시공면의 균열에 유입되어 균열을 자가 보수기능이 우수하며, 피시공면의 신축에도 대응할 수 있다. 따라서 방수구조에 크랙이 발생되지 않으며, 방수기능이 지속적으로 유지된다. Since the fluid gel layer 12 has fluidity, when a crack is generated on the surface to be coated, it flows into the crack and fills the crack. In particular, the fluid gel layer 12 is coated because the fluid persists without curing over time. It is excellent in self-repairing function by flowing into the cracks of the surface and can respond to the expansion and contraction of the surface to be constructed. Therefore, no crack is generated in the waterproof structure, and the waterproof function is maintained continuously.

또한, 상기 유동성 겔층(12)은 복합방수시트(10)가 피시공면에서 들뜨지 않고 피시공면에 효과적으로 잘 부탁되도록 하는 부착성을 부여한다.In addition, the flowable gel layer 12 imparts adhesion so that the composite waterproof sheet 10 is not easily lifted from the surface to be coated but is effectively applied to the surface to be coated.

한편, 상기 아스팔트펠트시트층(14)은 유동성 겔층(12)과 후술하는 우레탄방수층(20) 사이에서 우레탄방수층(20)을 지지한다. 피시공면에 균열이 발생되어 유동성 겔층(12)이 균열 내부로 유입되어 균열을 메우는 경우에 유동성 겔층(12)이 부분적으로 얇아질 수 있고, 이에 따라 우레탄방수층(20)이 함몰될 우려도 있는데, 아스팔트펠트시트층(14)이 우레탄방수층(20)을 지지함으로써 우레탄방수층(20)이 함몰되는 것이 방지된다. On the other hand, the asphalt felt sheet layer 14 supports the urethane waterproof layer 20 between the fluid gel layer 12 and the urethane waterproof layer 20 to be described later. When a crack is generated on the surface to be formed, the fluid gel layer 12 may flow into the crack to fill the crack, and the fluid gel layer 12 may be partially thinned, and accordingly, the urethane waterproof layer 20 may be sunk. , As the asphalt felt sheet layer 14 supports the urethane waterproof layer 20, the urethane waterproof layer 20 is prevented from being sunk.

피시공면(1)에 이러한 복합방수시트(10)를 단부가 겹쳐지도록 연속적으로 시공하는데, 복합방수시트(10)에 의해 피시공면(1) 위에 깔면 피시공면(1)에 유동성 겔층(12)과 아스팔트펠트시트층(14)이 한꺼번에 형성된다. The composite waterproof sheet 10 is continuously applied to the end surface of the composite waterproof sheet 10 so that the end surface overlaps. When the composite waterproof sheet 10 is laid on the surface 1, the fluid gel layer 1 12) and the asphalt felt sheet layer 14 are formed at once.

3) 복합방수시트(10) 위에 우레탄방수층(20)을 형성하는 단계3) forming a urethane waterproof layer 20 on the composite waterproof sheet 10

복합방수시트(10)의 아스팔트펠트시트층(14) 위에 우레탄방수제를 도포하여 우레탄방수층(20)을 형성한다. 사용가능한 우레탄방수제가 특별히 제한되지 않으므로 공지된 우레탄방수제 중에서 적절한 것을 선택하여 사용하는데, 우레탄방수제를 다수회 도포하여 우레탄방수층(20)을 형성한다. A urethane waterproofing agent 20 is formed on the asphalt felt sheet layer 14 of the composite waterproofing sheet 10 to form a urethane waterproofing layer 20. Since the urethane waterproofing agent that can be used is not particularly limited, an appropriate one is selected from known urethane waterproofing agents, and the urethane waterproofing layer 20 is formed by applying the urethane waterproofing agent multiple times.

이러한 우레탄방수층(20)은 우레탄방수층(20) 자체가 가지는 방수성에 의해 전체적인 방수구조의 방수성을 향상시킬 뿐만 아니라, 상기 복합방수시트(10)의 연결부위를 커버하며, 복합방수시트(10)를 태양열과 자외선으로부터 보호하는 보호층으로서의 기능도 한다. The urethane waterproof layer 20 not only improves the waterproofness of the overall waterproof structure by the waterproofness of the urethane waterproof layer 20 itself, but also covers the connecting portion of the composite waterproof sheet 10, and the composite waterproof sheet 10 It also functions as a protective layer that protects from solar heat and ultraviolet rays.

4) 우레탄방수층(20) 위에 차열탑코팅층(30)을 형성하는 단계4) forming a heat shield column coating layer 30 on the urethane waterproof layer 20
