ＰＶＣ 복합방수시트와 그 제작방법, 그리고 그 복합방수시트의 이음방법과 복합방수공법{Fuctional PVC waterproof sheet, manufacturing method of the sheet, joint of the sheet and waterproofing method using the sheet}PVC waterproof sheet, manufacturing method of the sheet, joint of the sheet and waterproofing method using the sheet}

본 발명은 구조물의 방수기술에 관한 것으로서, 더욱 상세하게는 단열성과 신축 저항성을 가지면서 수평이음을 실현할 수 있는 PVC 복합방수시트와, 그 복합방수시트의 바람직한 제작방법, 그리고 그 복합방수시트의 바람직한 이용방법에 관한 것이다. The present invention relates to a waterproofing technology of a structure, and more particularly, a PVC composite waterproof sheet capable of realizing horizontal joints with insulation and stretching resistance, a preferable manufacturing method of the composite waterproof sheet, and a preferable of the composite waterproof sheet. It is about how to use.

일반적으로 건물 옥상이나 주차장의 상부 등에는 누수를 방지하기 위해 방수공사를 하게 되는데, 시공상 편의로 일정 규격의 방수시트를 바탕면에 펼쳐 설치하는 시트방수공사가 널리 채택되고 있다.In general, waterproof construction is performed on the roof of a building or an upper part of a parking lot to prevent leakage, and for waterproof construction, sheet waterproof construction is widely adopted to install a waterproof sheet of a predetermined size on a base surface.

방수시트는 주요 재료에 따라 여러 종류가 있으나, PVC 등 합성고분자계 방수시트는 그 중 하나이다. 합성고분자계 방수용 시트는 신장률이 크기 때문에 건 축물 모체의 균열 또는 거동에 대한 추종성 및 순응성이 양호하고 내후성 내열성 등 충분한 내구성을 가지고 있어 통상 시트방수에 채택되어 사용되고 있다. 그러나, 큰 신장률 때문에 외기의 온도변화에 민감하게 대응하여 수축·팽창이 잘 일어났으며, 이는 방수시트의 방수성능을 저하시키는 원인으로 작용하였다. 즉, 방수시트의 수축·팽창정도가 크고 수축·팽창이 지속적으로 반복되면 방수시트는 부착 설치된 바탕면에서부터 용이하게 떨어지고 부착성능을 상실하게 되며 나아가 균열에 의한 파손이 생기기 쉬웠다. There are various kinds of waterproof sheet according to the main material, but synthetic polymer waterproof sheet such as PVC is one of them. Synthetic polymer waterproof sheet has a high elongation, and has good durability and conformity to cracking or behavior of the building matrix, and has sufficient durability such as weather resistance and heat resistance, and thus is commonly used for sheet waterproofing. However, due to the large elongation, shrinkage and expansion occurred well in response to the temperature change of the outside air, which acted as a cause of lowering the waterproof performance of the waterproof sheet. In other words, if the shrinkage and expansion degree of the waterproof sheet is large and the shrinkage and expansion is repeated continuously, the waterproof sheet easily falls from the installed base surface, loses the adhesion performance, and is more likely to be damaged by cracks.

한편, 방수시트는 규격화된 폭 및 길이(통상 폭 1-1.2m, 길이 15m)를 가지는 롤(roll)형의 시트의 형태로 제작되며 이를 바탕면 위에 일정 간격으로 펼쳐 설치하게 되므로, 필연적으로 시트 간의 이음부가 발생하게 된다. 이러한 이음부는 시트 방수에 있어 방수성능상 가장 취약한 부위로서 적절하게 처리되지 못할 경우 방수 하자의 원인이 되므로 이음부의 처리방법에 대한 다양한 방법이 개발되어 적용되고 있다. Meanwhile, the waterproof sheet is manufactured in the form of a roll-shaped sheet having a standardized width and length (usually 1-1.2 m in width and 15 m in length) and is installed at regular intervals on the base surface, thus inevitably making the sheet. The joints of the liver will occur. These joints are the most vulnerable parts in the waterproof performance of the sheet is a cause of waterproof defects if not properly treated, so a variety of methods for the treatment of the joint has been developed and applied.

도 1은 종래의 방수시트 이음부 처리방법을 보여주는 도면으로, 도 1(a)는 겹침이음에 의한 처리방법을 보여주며, 도 1(b)는 도막방수재의 채움이음에 의한 처리방법을 보여준다. 그러나, 이들 방식은 이음부가 두껍게 처리되기 때문에 표면이 울퉁불퉁하게 마감되는 문제를 갖는다. 이러한 문제는 시트방수를 그대로 외부에 노출시키는 방식(노출방수)으로 적용하는 것을 어렵게 했으며, 이에 따라 종래에는 시트방수 위에 도막방수를 처리하여 표면을 균일하게 처리할 수밖에 없었 다. 1 is a view showing a conventional waterproof sheet joint treatment method, Figure 1 (a) shows a treatment method by overlapping joints, Figure 1 (b) shows a treatment method by the filling joint of the coating film waterproofing material. However, these methods have a problem that the surface is roughly finished because the joint is processed thick. This problem has made it difficult to apply the sheet waterproof in a manner (exposed waterproof) as it is exposed to the outside, accordingly, in the prior art was to treat the surface of the coating on the sheet waterproof to uniformly treat the surface.

이하, 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

도 2는 본 발명에 따른 PVC 복합방수시트의 실시예를 보여주는데, 본 발명에 따른 PVC 복합방수시트(100)는, 섬유시트(110), PVC발포시트(120), PVC방수시트(130)의 적층으로 이루어짐과 아울러 PVC방수시트(130)의 단부가 단부압착부(130a)로 형성된다는데 기술적 특징이 있다. Figure 2 shows an embodiment of a PVC composite waterproof sheet according to the present invention, PVC composite waterproof sheet 100 according to the present invention, the fiber sheet 110, PVC foam sheet 120, of the PVC waterproof sheet 130 In addition to being laminated, there is a technical feature that an end portion of the PVC waterproof sheet 130 is formed as an end crimping portion 130a.

섬유시트(110)는 직포 또는 부직포로 마련되는데, 그 위에 적층되는 PVC발포시트(120)를 소정 두께로 성형시키는 한편 PVC발포시트(120)가 신축할 때 저항하여 PVC발포시트(120)의 변형 내지 찢어짐을 잡아주는 역할을 한다. PVC발포시트(120)는 PVC 발포재가 발포되어 소정 두께의 발포폼으로 형성된 것인데, 단열성과 내충격성을 발휘하는 역할을 하며, 아울러 그 위에 적층되는 PVC방수시트(130)가 신축할 때 저항하여 PVC방수시트(130)의 변형 내지 찢어짐을 잡아주는 역할을 한다. PVC방수시트(130)는 PVC 방수재료에 의해 소정 두께로 제작된 것인데, 실질적으로 방수성능을 발휘하는 역할을 하며, 본 발명은 방수시트로서의 용도가 본질적인 것을 감안하면 PVC발포시트(120)의 2배 정도의 두께가 적당하다. 통상의 PVC 재료로 제작한다면 0.5㎜ 정도 두께의 PVC발포시트(120)와 1㎜ 정도 두께의 PVC방수시트(130)이면 적당하다. 비록 PVC방수시트(130)는 신장률이 크지만, PVC방수시트(130) 아래로 신장률이 작은 순서대로 PVC발포시트(120)와 부직포가 적층되기 때문에 본 발명에 따른 PVC 복합방수시트(100)는 치수안정성을 확보할 수 있다. 또한, 본 발명에 따른 PVC 복합방수시트(100)는 전체적으로 PVC 계열로 통일되기 때문에 일관적인 물성을 발휘한다.Fiber sheet 110 is provided with a woven or non-woven fabric, while forming a PVC foam sheet 120 to be laminated thereon to a predetermined thickness while the PVC foam sheet 120 is stretched to resist deformation of the PVC foam sheet 120 To serve to hold the tear. The PVC foam sheet 120 is formed of a foam foam of a predetermined thickness by foaming the PVC foam, and serves to exert heat insulation and impact resistance, and also when the PVC waterproof sheet 130 is laminated on it to resist PVC It serves to hold deformation or tear of the waterproof sheet 130. PVC waterproof sheet 130 is made of a PVC waterproof material to a predetermined thickness, and serves to exhibit substantially waterproof performance, the present invention is considered that the use as a waterproof sheet is essentially two of the PVC foam sheet 120 About twice the thickness is appropriate. If it is made of a conventional PVC material is a PVC foam sheet 120 and 0.5mm thick PVC waterproof sheet 130 of about 1mm thick is suitable. Although the PVC waterproof sheet 130 has a large elongation, the PVC composite waterproof sheet 100 according to the present invention because the PVC foam sheet 120 and the nonwoven fabric are laminated in the order of the small elongation under the PVC waterproof sheet 130 is Dimensional stability can be secured. In addition, the PVC composite waterproof sheet 100 according to the present invention exhibits consistent physical properties because it is unified as a whole PVC-based.

특히, 본 발명에 따른 PVC 복합방수시트(100)에서 PVC방수시트(130)는 단부가 압착되어 중앙부보다 두께가 얇아진 단부압착부(130a)로 형성된다. 단부압착부(130a)는 본 발명에 따른 PVC 복합방수시트(100)의 표면을 균일하게 수평이음하는데 기여하며, 단부압착부(130a)에 의한 수평이음에 관해서는 후술한다. 단부압착부(130a)는 PVC방수시트(130)를 압착시켜 형성되기 때문에 중앙부에 비해 단면 두께가 얇아질 뿐 중앙부와 동일한 성능을 그대로 보유한다. 단부압착부(130a)는 2㎝ 정도의 폭과 중앙부의 절반 정도 두께가 적당하며, 가령 1㎜ 정도 두께의 PVC방수시트(130)라면 단부압착부(130a)는 0.5㎜ 정도 두께로 형성시킨다.In particular, in the PVC composite waterproof sheet 100 according to the present invention, the PVC waterproof sheet 130 is formed as an end compression portion 130a, the end of which is thinner than the central portion. The end pressing portion 130a contributes to uniformly horizontally joining the surface of the PVC composite waterproof sheet 100 according to the present invention, and the horizontal joining by the end pressing portion 130a will be described later. Since the end pressing portion 130a is formed by pressing the PVC waterproof sheet 130, the end portion thickness is thinner than the central portion, and retains the same performance as the central portion.

도 3은 도 2의 PVC 복합방수시트(100)의 제작과정을 보여주며, 이를 참고하여 본 발명에 따른 PVC 복합방수시트(100)의 제작방법을 단계적으로 살펴본다.3 shows a manufacturing process of the PVC composite waterproof sheet 100 of FIG. 2, and looks at the manufacturing method of the PVC composite waterproof sheet 100 according to the present invention step by step.

먼저 분말상태의 PVC발포재를 혼입한 원료로 PVC시트를 제작한다((a)단계). 이어 직포 또는 부직포로 섬유시트(110)를 준비하고, PVC시트와 섬유시트(110)를 합착하여 합착시트를 제작한다((b)단계). 다음으로 합착시트를 발포시켜 PVC시트를 PVC발포시트(120)로 만든다((c)단계). 그리고 PVC방수시트(130)를 준비한 후, 발포된 합착시트에서 PVC발포시트(120) 표면에 PVC방수시트(130)를 합착하여 복합방수시트를 제작한다((d)단계). 이때 상기 (d)단계는, PVC방수시트(130)를 재생 PVC에 의한 제1방수시트(131)와 신생 PVC에 의한 제2방수시트(132)로 구분하여 준비하고((d1)단계), 발포된 합착시트에서 PVC발포시트(120) 표면에 제1방수시트(131)를 합착시키고((d2)단계), 제1방수시트(131) 표면에 제2방수시트(132)를 합착시키는 과정((d3)단계)으로 세분화하여 진행할 수 있다. 마지막으로 상기 복합방수시트에서 PVC방수시트(130) 표면 단부를 열을 가하면서 압착하여 단부압착부(130a)를 형성시킨다((e)단계). 이와 같은 일련의 과정을 거치면 단부압착부(130a)가 형성된 PVC 복합방수시트(100)를 완성된다. 상기한 PVC 복합방수시트(100)는 시공 및 취급이 용이하도록 일정한 폭 및 길이(통상 폭 1~1.2m, 길이 15m)를 가지는 롤(roll) 형태로 제작하면 된다.First, a PVC sheet is manufactured from a raw material mixed with a PVC foam in a powder state (step (a)). Subsequently, the fiber sheet 110 is prepared with a woven or nonwoven fabric, and the PVC sheet and the fiber sheet 110 are bonded to each other to prepare a bonding sheet (step (b)). Next, by foaming the bonding sheet to make a PVC sheet PVC foam sheet 120 ((c) step). Then, after preparing the PVC waterproof sheet 130, by combining the PVC waterproof sheet 130 on the surface of the PVC foam sheet 120 in the foamed bonding sheet to produce a composite waterproof sheet ((d) step). At this time, in step (d), the PVC waterproof sheet 130 is prepared by dividing the first waterproof sheet 131 by the recycled PVC and the second waterproof sheet 132 by the new PVC ((d1) step), Process of bonding the first waterproof sheet 131 to the surface of the PVC foam sheet 120 in the foamed bonding sheet (d2), and bonding the second waterproof sheet 132 to the surface of the first waterproof sheet 131 You can proceed by subdividing (step (d3)). Finally, the composite waterproof sheet is pressed while applying heat to the surface end of the PVC waterproof sheet 130 to form an end crimping unit 130a (step (e)). Through such a series of processes is completed PVC composite waterproof sheet 100 is formed with the end pressing portion (130a).

도 4는 도 2의 PVC 복합방수시트(100)를 이용하여 완성한 이음구조를 보여준다. 본 발명에 따른 PVC 복합방수시트(100)의 이음구조는, 섬유시트(110)를 아래로 하여 단부압착부(130a)를 서로 이웃하게 하면서 이격하게 병행 설치되는 상기한 PVC 복합방수시트(100); 서로 이웃하는 단부압착부(130a) 위에 덧씌워져 상기 PVC 복합방수시트(100) 상호 간을 연결하는 방수실란트(210); PVC필름막(222) 양 표면에 직포 또는 부직포에 의한 섬유시트(221, 223)가 부착된 얇은 띠 형태의 부재로, 서로 이웃하는 단부압착부(130a)에 동시에 걸쳐지게 위치하도록 배치되는 한편 상기 방수실란트(210) 내부에 묻히도록 설치되는 PVC복합필름(220);을 포함하여 구성된다. 상기 PVC 복합방수시트(100)에서 PVC방수시트가 1㎜ 정도 두께이고 단부압착부(130a)가 0.5㎜ 정도 두께라면, 상기 PVC복합필름(220)은 0.3㎜정도의 두께로 마련하면 적당하며, 상기 방수실란트(210)는 0.2㎜ 정도 두께로 마련하여 사이에 PVC복합필름이 위치하게 하면 적당하다.4 shows a joint structure completed using the PVC composite waterproof sheet 100 of FIG. The joint structure of the PVC composite waterproof sheet 100 according to the present invention, the PVC composite waterproof sheet 100 is installed in parallel with the fiber sheet 110 to be spaced apart while adjacent to the end pressing portion (130a) to each other. ; A waterproof sealant 210 which is overlaid on adjacent end-compression parts 130a to connect the PVC composite waterproof sheet 100 to each other; A thin strip-shaped member having the fiber sheets 221 and 223 formed by a woven or nonwoven fabric on both surfaces of the PVC film film 222, which is disposed so as to span the adjacent end-compression parts 130a at the same time while being waterproof. It is configured to include; PVC composite film 220 is installed to be buried in the sealant (210). In the PVC composite waterproof sheet 100, if the PVC waterproof sheet is about 1 mm thick and the end crimping portion 130a is about 0.5 mm thick, the PVC composite film 220 is suitable to provide a thickness of about 0.3 mm, The waterproof sealant 210 is suitable to provide a thickness of about 0.2 mm to position the PVC composite film between.

PVC 복합방수시트(100) 상호 간의 이격거리는 5㎜ 정도이면 적당하며, PVC복합필름(220)은 방수실란트(210)를 1차 도포 부분(211)과 2차 도포 부분(212)으로 구분하여 그 사이에 위치시킴으로써 방수실란트(210)에 묻히도록 설치할 수 있다. 특히 PVC복합필름(220)은 양 표면이 섬유시트(221, 223)로 처리된 것이므로 방수실란트(210)에 함침되면서 안정적으로 묻힌다. 한편 방수실란트(210)는 방수성능을 기본으로 가지면서 PVC방수시트(130)보다 고탄성을 가지는 재료가 바람직한데, 그래야 방수실란트(210)가 신축줄눈으로 역할할 수 있다. 즉, 방수실란트(210)가 고탄성이면 PVC방수시트(130)의 신축에 유연하게 대응할 수 있기 때문에 PVC방수시트(130)의 신축에도 이음구조를 그대로 유지할 수 있는 것이다. 고탄성 방수실란트(210)를 위한 구체적인 재료로는 무기질계열의 방수실란트(210)와 우레탄계열의 방수실란트(210)가 있다. 다만 PVC복합필름(220)은 양 표면의 섬유시트(221, 223)로 신축이 제어되기 때문에 PVC방수시트(130)의 신축에 대응하지 못하므로, PVC복합필름(220)은 그 폭이 PVC 복합방수시트(100) 상호 간의 이격거리보다 넓으면서 PVC 복합방수시트(100) 상호 간 단부압착부(130a)의 배치거리보다 좁게 준비되어 방수실란트(210)에 묻혀야 할 것이다. PVC composite waterproof sheet 100 is suitable if the separation distance between each other 5mm, PVC composite film 220 is divided into a waterproof coating 210, the primary coating portion 211 and the secondary coating portion 212 and the It can be installed to be buried in the waterproof sealant 210 by being positioned between. In particular, since the PVC composite film 220 is treated on both surfaces with the fiber sheets 221 and 223, the PVC composite film 220 is stably buried while being impregnated with the waterproof sealant 210. On the other hand, the waterproof sealant 210 has a high elasticity than the PVC waterproof sheet 130 while having a waterproof performance as a basic, so that the waterproof sealant 210 may act as a stretch joint. That is, if the waterproof sealant 210 is highly elastic, it can flexibly respond to the expansion and contraction of the PVC waterproof sheet 130, so that the joint structure can be maintained intact even when the PVC waterproof sheet 130 is stretched. Specific materials for the high elastic waterproof sealant 210 include the inorganic sealant 210 and the urethane-based waterproof sealant 210. However, the PVC composite film 220 does not correspond to the expansion and contraction of the PVC waterproof sheet 130 because the expansion and contraction is controlled by the fiber sheet (221, 223) of both surfaces, PVC composite film 220 is the width of the PVC composite The waterproof sheet 100 is to be prepared to be narrower than the distance between the PVC composite waterproof sheet 100 and the end distance between the end pressing portion 130a between each other to be buried in the waterproof sealant 210.

상기와 같이 완성되는 본 발명에 따른 이음구조는 두께가 얇은 단부압착부(130a)에 방수실란트(210)와 PVC복합필름(220)을 채우는 방식이기 때문에 전체적으로 균일한 두께로 완성된다. 더군다나 방수성능이 취약하기 쉬운 이음부에 PVC복합필름(220)이 걸쳐 설치되기 때문에 방수성능의 연속성을 확보할 수 있다.The joint structure according to the present invention completed as described above is completed with a uniform thickness as a whole because it is a method of filling the waterproof sealant 210 and the PVC composite film 220 in the thin end pressing portion (130a). Furthermore, since the PVC composite film 220 is installed over the joints where the waterproof performance is easily vulnerable, the continuity of the waterproof performance can be secured.

도 5는 도 4의 PVC 복합방수시트 이음구조가 적용하면서 실시한 복합방수공법의 시공순서도를 보여주며, 이를 참고하여 본 발명에 따른 복합방수공법을 단계적으로 살펴본다.Figure 5 shows the construction sequence diagram of the composite waterproof method carried out while applying the PVC composite waterproof sheet joint structure of Figure 4, with reference to this it will take a step-by-step look at the composite waterproof method according to the present invention.

먼저 바탕면(c)을 정리한다((a)단계). 바탕면(c)을 정리하는 과정에는 프라이머를 도포하는 과정을 더 포함하여 콘크리트 바탕면의 내구성 및 내수성을 확보할 수 있다. 이어 바탕면(c) 위에 도막방수재를 도포하여 도막방수층(310)을 형성시키며((b)단계), 이때 도막방수재는 무기질 도막방수재가 바람직하다. 무기질 도막방수재는 콘크리트 바탕면과의 접착력이 우수하고 습기가 있는 상태에서도 들뜸현상없이 도막방수층(310)을 형성한다는 점에서 유리하며, 나아가 작업 중 유해물질이 발생하지 않아 친환경적이다. 도막방수재에 의한 도막방수층(310) 위로는 PVC 복합방수시트(100)가 적층되기 때문에 도막방수재는 1회의 도포로도 충분하다.First, the base surface (c) is arranged (step (a)). The process of arranging the base surface (c) may further include applying a primer to ensure durability and water resistance of the concrete base surface. Subsequently, the coating film waterproofing material is coated on the base surface (c) to form the coating waterproofing layer 310 (step (b)), wherein the coating waterproofing material is preferably an inorganic coating waterproofing material. The inorganic coating waterproofing material is advantageous in that it has excellent adhesion to the concrete base surface and forms the coating waterproofing layer 310 without lifting even in a humid state, and furthermore, it is environmentally friendly since no harmful substances are generated during the operation. Since the PVC composite waterproof sheet 100 is laminated on the coating waterproof layer 310 by the coating waterproofing material, the coating waterproofing material is sufficient for one application.

다음으로 도 4와 같은 이음구조를 구현하면서 PVC 복합방수시트(100)를 도막방수층(310) 위에 부착 설치하며((c)단계), 이로써 이음부가 수평으로 균일하게 처리된 복합방수구조가 완성된다. 이와 같은 복합방수구조는 PVC 복합방수시트(100)가 외부로 노출되는 형태이기 때문에 미끄럼 방지를 위해 표면 요철 등의 거친 표면으로 마감처리된 PVC 복합방수시트(100)를 적용하는 것이 바람직하다. 나아가 도시하지 않았지만 이음부의 방수실란트(210) 표면 위에는 얇은 코팅막을 형성시켜 방수실란트(210)를 보호함이 바람직하며, 이때 코팅막은 자와선 차단효과가 있는 재료를 이용하는 것이 좋겠다.Next, while implementing the joint structure as shown in Figure 4, the PVC composite waterproof sheet 100 is attached to the coating layer 310 (step (c)), thereby completing a composite waterproof structure in which the joint is treated uniformly horizontally. . Since the composite waterproof structure is a form in which the PVC composite waterproof sheet 100 is exposed to the outside, it is preferable to apply the PVC composite waterproof sheet 100 treated with a rough surface such as surface irregularities to prevent slipping. Furthermore, although not shown, it is preferable to form a thin coating film on the waterproof sealant 210 surface of the joint to protect the waterproof sealant 210, and the coating film is preferably made of a material having an effect of blocking the rays.

한편, 본 발명은 탈기로(321)를 형성하고 탈기반(330)을 설치함으로써 통기구조로 완성할 수 있다. 구체적으로 통기구조는 상기 (c)단계를, (c1)도막방수층(310) 위에 바둑판 모양의 탈기로(321)를 형성시키면서 탈기로 주변에 본드를 도포하는 단계; (c2)단부압착부(130a)가 서로 이웃하면서 이격하도록 PVC 복합방수시트(100)를 병행 설치하되, PVC 복합방수시트(100) 상호 간 이격 이음부를 탈기로(321) 사이에 위치시키면서 PVC 복합방수시트(100)를 상기 도막방수층(310) 위의 본드(322)에 부착 설치하는 단계; (c3)서로 이웃하는 단부압착부(130a) 위에 방수실란트를 1차 도포(211)하면서 상기 PVC 복합방수시트(100) 상호 간을 서로 연결하되, 1차 방수실란트(211)는 탈기로(321)를 보전하면서 도포하는 단계; (c4)1차 방수실란트(211) 위로 PVC복합필름(220)을 연속적으로 이어지게 설치하되, PVC복합필름(220)이 서로 이웃하는 단부압착부(130a)에 동시에 걸쳐지게 위치하도록 설치하는 단계; (c5)PVC복합필름(220) 위에 방수실란트를 2차 도포(212)하여 PVC복합필름(220)을 방수실란트(210)에 매설시키는 단계; (c6)도막방수층(310) 위의 탈기로(321)에 고정되는 한편 PVC 복합방수시트(100)를 관통하게 위치하는 탈기반(330)을 설치하는 단계;로 세분화함으로써 완성할 수 있다. 상기 (c1)단계, (c3)단계 및 (c4)단계를 통해 탈기로(321) 형성위치에는 본드 내지 1차 방수실란트(211)가 도포되지 않은 상태에서 PVC복합필름(220)이 덧씌워지기 때문에 바둑판 모양의 탈기로(321)는 그대로 보전되어 연속성이 유지되며, 이에 따라 내부 습기는 탈기로(321)를 따라 최종 탈기반(330)을 통해 원활히 배출된다.On the other hand, the present invention can be completed in a ventilated structure by forming the degassing 321 and installing the debase 330. Specifically, the ventilation structure is the step of (c), (c1) applying a bond around the degassing while forming a checkerboard degassing 321 on the coating layer 310; (c2) While installing the PVC composite waterproof sheet 100 in parallel so that the end compression parts 130a are spaced apart from each other, the PVC composite waterproof sheet 100 is placed between the degassing joints 321 between the degassing joints 321. Attaching the waterproof sheet 100 to the bond 322 on the coating layer 310; (c3) While the waterproof sealant is first applied to the neighboring end pressing portions 130a (211), the PVC composite waterproof sheet 100 is connected to each other, but the primary waterproof sealant 211 is degassed (321) Applying while preserving); (c4) installing the PVC composite film 220 continuously on the first waterproof sealant 211 continuously, and installing the PVC composite film 220 such that the PVC composite film 220 is placed on the neighboring end compression parts 130a at the same time; (c5) embedding the PVC composite film 220 in the waterproof sealant 210 by second coating 212 the waterproof sealant on the PVC composite film 220; (c6) while being fixed to the degassing 321 on the coating layer 310, while installing the desorption base 330 located through the PVC composite waterproof sheet 100; can be completed by subdividing. The PVC composite film 220 is overlaid in the state where the bond to the primary waterproof sealant 211 is not applied to the degassing 321 forming position through the steps (c1), (c3) and (c4). Therefore, the checkerboard degassing 321 is maintained as it is to maintain the continuity, accordingly, the internal moisture is smoothly discharged through the final de-base 330 along the degassing 321.
