본 발명은 건축물의 방수재료 및 방수공법에 관한 것으로, 보다 상세하게는 방수층이 삽입된 시멘트몰탈 복합방수패널 및 그를 이용해 옥상에 방수층 및 보호층을 동시에 형성하는 방법에 관한 것이다.The present invention relates to a waterproof material and a waterproofing method of a building, and more particularly, to a cement mortar composite waterproof panel having a waterproof layer inserted therein and a method of simultaneously forming a waterproof layer and a protective layer on a roof using the same.

옥상의 경우, 우수의 실내로의 침투방지를 위해 일반적으로 “도막방수”와 “시트방수”가 사용되고 있다. 이때 “도막방수”는 방수성능의 액상재를 옥상표면에 도포?경화시켜 얇은 방수층을 형성하며, “시트방수”는 공장에서 성형생산된 방수시트를 현장에 펼쳐 깔은 후 이음부를 연결하여 방수층을 형성한다.In the case of the rooftop, "film waterproof" and "sheet waterproof" are generally used to prevent rainwater from penetrating into the interior. At this time, “waterproof film” is applied to the roof surface to harden the liquid material to form a thin waterproof layer. The “waterproof sheet” spreads the waterproof sheet produced at the factory on the site and connects the joints to connect the waterproof layer. Form.

그러나 도막방수는 바탕체와 전면접착되는 관계로 바탕거동의 영향을 받아 균열이 발생하며(도 4 참조), 시트방수는 공장생산되는 관계로 시트크기가 한정되어 있어 현장시공 시 필연적으로 이음부가 발생하는데, 이 부위에 응력이 집중하여 파단하자가 발생한다(도 5 참조).However, since the waterproofing of the coating film is completely bonded to the base body, cracks are generated under the influence of the ground behavior (see FIG. 4), and the sheet waterproofing is factory-produced. , The stress is concentrated in this region, and a fracture defect occurs (see FIG. 5).

또한 도막방수재와 시트방수재는 유기재료에 속하며, 실외환경에 직접 노출 되는 경우 자외선 내구성이 부족하여 열화가 진행된다. 따라서 표면 상부에 자외선 차단제를 추가 도포하는데, 이를 통해 작업공정이 추가되고 공사비(자재비+시공비)가 증가하게 된다. 특히 중량물이나 화기 또는 화학물로부터의 보호가 요구되는 경우는 이 보다 많은 작업이 추가된다. 방수층 상부에 보호몰탈 또는 누름콘크리트를 시공해야 할 뿐만 아니라, 누름콘크리트의 균열방지를 위한 saw-cut와 줄눈코킹 작업을 수행하여야 한다.In addition, the coating waterproofing material and sheet waterproofing material belong to organic materials, and when exposed directly to the outdoor environment, deterioration is progressed due to insufficient UV durability. Therefore, an additional sunscreen is applied to the upper surface, which adds a work process and increases construction cost (material cost + construction cost). More work is added especially when protection from heavy objects, fires or chemicals is required. In addition to installing protective mortar or pressed concrete on top of the waterproof layer, saw-cut and joint caulking operations to prevent cracking of pressed concrete should be performed.

특히 도막방수와 시트방수 모두 바탕상태에 영향을 받는다. 바탕의 요철이 심한 경우, 도막방수에서는 방수층의 두께가 불균일하게 되며, 시트방수에서는 천공이 발생한다. 바탕에 패인 곳이 있으면, 도막방수에서는 재료사용량이 증가하며, 시트방수에서는 신장과 꺼짐현상이 나타난다. In particular, both the waterproof film and the sheet water are affected by the ground state. If the unevenness of the base is severe, the thickness of the waterproof layer becomes uneven in waterproofing the coating, and the perforation occurs in the waterproofing of the sheet. If there is a recess in the background, the material usage increases in the waterproofing of the film, and the elongation and the off phenomenon appear in the waterproofing of the sheet.

결론적으로 방수층의 두께가 확보되고, 별도의 보호층 시공이 필요없는 그리고 바탕상태로부터 방수층이 보호될 수 있는 일체형 복합 방수재가 요구되며, 또한 일체형 복합 방수재 간의 이음부가 파단되지 않는 이음공법이 요구된다.In conclusion, there is a need for an integrated composite waterproof material that can secure the thickness of the waterproof layer, does not need a separate protective layer construction, and can protect the waterproof layer from the ground state, and also requires a joint method in which the joints between the integrated composite waterproof materials are not broken.

본 발명은 상기한 종래기술의 문제점을 감안하여 안출된 것으로, 방수층과 보호층을 동시에 건식공법으로 간편하게 시공이 가능하여, 공정이 단축되고 공사비가 절약되는 일체형 시멘트몰탈 복합방수패널을 제공하는 것을 그 목적으로 한다.

도 1, 2를 참조하면 본 발명에 따른 일체형 시멘트몰탈 복합방수패널(10, 이하 '복합방수패널' 또는 '패널'이라고도 한다)은, 일종의 프리캐스트 패널로서, 도 막방수재로 구성되는 방수층(11)과 방수층(11)의 양면에 적층되는 시멘트몰탈층(12)으로 구성된다. 즉, 방수층(11)을 가운데에 둔 샌드위치 구조의 기성 시멘트 제품이다. 1 and 2, the integrated cement mortar composite waterproof panel 10 (hereinafter also referred to as 'composite waterproof panel' or 'panel') according to the present invention is a kind of precast panel, which is a waterproof layer 11 composed of a film waterproof material. ) And a cement mortar layer 12 laminated on both sides of the waterproof layer 11. That is, it is a ready-made cement product of the sandwich structure which centered the waterproof layer 11 on it.

방수층(11)은 연속적인 막을 형성하여 복합방수패널에 방수성능을 부여하는 것으로, 공지의 도막방수재로부터 선택될 수 있다. 방수층(11)을 구성하는 도막방수재로서는, 우레탄고무계, 아크릴고무계, 고무아스팔트계, 클로로프렌계, 아크릴수지계, 폴리에스테르계 또는 무기질탄성계가 사용될 수 있다. 방수층(10)의 두께는 방수층을 구성하는 도막방수재의 성질을 고려하여 적절히 선택되며 1.5~3.0mm 정도로 형성될 수 있다. The waterproof layer 11 forms a continuous film to impart waterproof performance to the composite waterproof panel, and may be selected from known coating waterproof materials. As the coating waterproof material constituting the waterproof layer 11, urethane rubber, acrylic rubber, rubber asphalt, chloroprene, acrylic resin, polyester or inorganic elasticity may be used. The thickness of the waterproof layer 10 is appropriately selected in consideration of the properties of the coating waterproof material constituting the waterproof layer and may be formed about 1.5 ~ 3.0mm.

방수층(11)의 양면에는 시멘트몰탈층(12)이 형성된다. 이 시멘트몰탈층(12)은 방수층(11)의 하부에 형성되어 콘크리트 바탕면에 접하는 바탕 시멘트몰탈층(121)과 방수층(11)의 상부에 형성되어 방수층(11)을 보호하는 보호 시멘트몰탈층(122)으로 구성된다. 시멘트몰탈층(12)은 시멘트, 물, 모래 및 폴리머를 혼합하여 이루어진 것으로 필요에 따라 혼화제가 더 추가될 수 있다. 예를 들어 시멘트몰탈층(12)은 중량비로 시멘트 45.21, 속경제 2.71, 무수석고 2.71, 유동화제 0.09, 폴리머 0.45, 실리카흄 3.62, 규사 36.17 그리고 소량의 화이버를 배합하여 제조될 수 있으며, 바탕 및 보호 시멘트몰탈층(12)의 두께는 각각 1.5~2.0cm 정도이고 크기는 35cm x 35cm 정도될 수 있다. 그리고 보호 시멘트몰탈층(122)의 상면은 외부로 노출되는 부분으로서 장식성을 높이기 위해 다양한 문양이 형성될 수 있다. Cement mortar layer 12 is formed on both sides of the waterproof layer 11. The cement mortar layer 12 is formed on the base cement mortar layer 121 and the waterproof layer 11 which are formed under the waterproof layer 11 to contact the concrete base surface to protect the waterproof layer 11. Consisting of 122. Cement mortar layer 12 is made of a mixture of cement, water, sand and a polymer may be added to the admixture if necessary. For example, the cement mortar layer 12 may be manufactured by combining cement 45.21, fast economic 2.71, gypsum 2.71, fluidizing agent 0.09, polymer 0.45, silica fume 3.62, silica sand 36.17 and a small amount of fibers in a weight ratio. The cement mortar layer 12 may have a thickness of about 1.5 to 2.0 cm and a size of about 35 cm x 35 cm, respectively. And the upper surface of the protective cement mortar layer 122 is a portion that is exposed to the outside may be formed in various patterns to enhance the decorative properties.

한편, 방수층(11)은 네측면측의 단부 즉, 노출면이 다른 부분보다 확장된 형 태를 가져 이웃하는 패널과의 이음 면적을 확대하도록 한 확장이음부(111)를 갖는다. 방수층(11)의 확장이음부(111)는 중심부보다 두께가 더 두꺼운 형상을 갖는 것으로 그 형상은 도시된 바와 같이 삼각형 형상을 가질 수 있다. 따라서 후술하는 바와 같이 본 발명이 따른 복합방수패널을 단차를 두고 포설할 때에도 그 이음부에서 방수층이 연속적으로 서로 연결될 수 있도록 한다. 확장이음부(111)의 형상은 도시된 삼각형 형상에 한정되는 것은 아니며 중심부보더 더 두꺼운 두께를 가져 실링재에 의해 이웃하는 패널의 방수층이 서로 연결될 수 있도록 하는 형상이면 된다. On the other hand, the waterproof layer 11 has an expansion joint 111 to enlarge the joint area with the neighboring panel in the end of the four sides, that is, the exposed surface has an expanded form than the other portion. The expansion joint 111 of the waterproof layer 11 has a thicker shape than the center portion, and the shape may have a triangular shape as shown. Therefore, as described below, even when laying the composite waterproof panel according to the present invention with a step so that the waterproofing layers can be continuously connected to each other at its joints. The shape of the expansion joint 111 is not limited to the illustrated triangular shape, but may be a shape having a thicker thickness than the center portion so that the waterproof layers of neighboring panels can be connected to each other by the sealing material.

이상과 같이 본 발명에 따른 복합방수패널은 소정의 크기에 제작된 몰드에 시멘트몰탈을 일정 두께로 바르고 그 위에 도막방수재를 도포한 다음 다시 그 위에 시멘트몰탈을 바르고 경화시켜 제작된다. 즉, 방수층을 미리 형성한 기성 시멘트 제품으로서, 바탕면을 편평하게 처리하는 고름 몰탈 기능을 하는 바탕 시멘트몰탈층과 방수층을 보호하는 보호 시멘트몰탈층이 일체로 형성되어 있어 단순히 바탕면을 고르고 본 발명에 따른 복합방수패널을 포설한 다음 이음부에 실링재를 충진하는 것만으로 방수공사를 완료할 수 있다.As described above, the composite waterproof panel according to the present invention is manufactured by coating cement mortar with a predetermined thickness on a mold manufactured to a predetermined size, applying a coating waterproofing material thereon, and then applying cement mortar on it and curing. That is, as a ready-made cement product having a waterproof layer formed in advance, a ground cement mortar layer having a pulp mortar function to treat the base surface flatly and a protective cement mortar layer protecting the waterproof layer are integrally formed, so that the base surface is simply selected and the present invention is selected. After installing the composite waterproof panel according to the above, the waterproofing work can be completed only by filling the sealing material in the joint.

다른 방법으로는 바탕 시멘트몰탈층과 보호 시멘트몰탈층을 미리 성형한 다음, 이들을 방수층 두께만큼 이격하여 설치하고 그 틈에 방수재를 붓고 경화시켜 복합방수패널을 제작할 수도 있다.Alternatively, the base cement mortar layer and the protective cement mortar layer may be pre-molded, and then spaced apart by the thickness of the waterproof layer, and the waterproof material may be poured and cured to form a composite waterproof panel.

도 3(a)은 본 발명에 따른 복합방수패널을 이용해 옥상을 방수하는 시공방법을 개략적으로 나타낸 단면도이고, 도 3(b)는 확장이음부가 없는 복합방수패널을 시공한 상태를 개략적으로 나타낸 단면도이다.Figure 3 (a) is a cross-sectional view schematically showing a construction method for waterproofing the roof using the composite waterproof panel according to the present invention, Figure 3 (b) schematically shows a state in which the composite waterproof panel without expansion joints construction It is a cross section.

도 3(a)를 참조하면, 방수를 하고자 하는 대상 몰탈 또는 콘크리트면(20)을 바탕처리하고, 도 1를 참조하여 설명한 본 발명에 따른 복합방수패널(10)을 포설한다. 다음으로, 복합방수패널(10)의 이음부에 실링재(30)를 충진한다. 복합방수패널(10)을 포설하면 복합방수패널(10) 사이에 간격이 생기는데 이 부분에 복합방수패널(10)의 방수층(11)을 구성하는 도막방수재와 동일한 재료로 된 실링재(30)를 충진한다. 이렇게 방수층(11)과 실링재(30)을 서로 동일재질로 구성함으로서 이들 간의 접합성이 양호하게 된다. Referring to FIG. 3 (a), the target mortar or concrete surface 20 to be waterproofed is grounded, and the composite waterproof panel 10 according to the present invention described with reference to FIG. 1 is installed. Next, the sealing material 30 is filled in the joint portion of the composite waterproof panel 10. When the composite waterproof panel 10 is installed, a gap is formed between the composite waterproof panels 10, and the sealing material 30 made of the same material as the coating waterproof material constituting the waterproof layer 11 of the composite waterproof panel 10 is filled in this portion. do. Thus, as the waterproof layer 11 and the sealing material 30 are made of the same material, the bonding between them becomes good.

도 3(b)는 확장이음부가 없는 경우를 도시한 것으로, 복합방수패널(10)이 서로 단차를 두고 연결될 경우 이웃하는 복합방수패널(10)의 방수층(11)이 단속되어 연속적인 막을 형성하지 못해 복합방수패널(10) 간의 이음매에서 누수가 발생될 수 있다. 따라서 본 발명에서는 방수층(11)의 양측단부에 확장이음부(111)를 형성하여 복합방수패널(10)이 서로 단차를 두고 연결될 경우에도 충진된 실링재(30)에 의해 방수층(11)이 연속될 수 있도록 하였다. 또한, 충진된 실링재(30)가 신축줄눈으로서 기능하므로 복합방수패널(10) 사이의 이음부에서 누수가 생기는 것을 효적으로 방지할 수 있다. FIG. 3 (b) shows the case where there is no expansion joint. When the composite waterproof panels 10 are connected to each other with a step, the waterproof layer 11 of the neighboring composite waterproof panels 10 is interrupted to form a continuous film. Failure to do so may cause leakage at the joints between the composite waterproof panels 10. Therefore, in the present invention, the expansion joints 111 are formed at both end portions of the waterproof layer 11 so that the waterproof layer 11 may be continuous by the sealing material 30 filled even when the composite waterproof panels 10 are connected with a step difference from each other. To make it possible. In addition, since the filled sealing material 30 functions as a stretch joint, leakage of water at the joints between the composite waterproof panels 10 can be effectively prevented.
