폴리우레아를 이용한 조인트 강화 복합방수공법{Complex Waterproofing Method of Polyurea}Joint reinforcement composite waterproofing method using polyurea{Complex Waterproofing Method of Polyurea}

본 발명은 폴리우레아를 이용한 조인트 강화 복합방수공법에 관한 것으로서, 더욱 상세하게는, 단열시트와 폴리우레아로 이루어진 도막층을 형성하여, 상기 단열시트에 의한 단열성 및 자체 탄성으로 외력에 대한 대응성을 향상시키고, 폴리우레아의 도막층에 의해 단열시트들의 조인트부분에 대한 방수성능 유지 및 강화시켜 상호 보완적인 방수층을 구성함으로써, 기본적인 방수성능 향상은 물론, 외력에 대한 대응성과 조인트 부분의 보강성 증진 등으로 방수시공 경쟁력을 강화하는 폴리우레아를 이용한 조인트 강화 복합방수공법에 관한 것이다.The present invention relates to a joint reinforced composite waterproofing method using polyurea, and more particularly, by forming a coating layer made of a heat insulating sheet and polyurea, the heat insulating property by the heat insulating sheet and its own elasticity to respond to external force In addition, by forming a complementary waterproofing layer by maintaining and reinforcing the waterproofing performance of the joints of the insulating sheets by the coating layer of polyurea, not only the basic waterproofing performance is improved, but also the response to external forces and the reinforcement of the joints are improved. It relates to a joint reinforcement composite waterproofing method using polyurea that enhances the waterproof construction competitiveness.

일반적으로, 옥상 슬라브, 건물의 지하실 또는 각종 유체 저장탱크 등의 콘크리트 구조물에는 방수력이 약하기 때문에 빗물 또는 지하수 등이 스며들고, 이로 인해 콘크리트 구조물의 자체 결합력을 떨어뜨릴 뿐만 아니라 온도 변화에 따른 물의 체적변화에 의해서 콘크리트에 균열이 발생되어 콘크리트 구조물의 수명을 단축시키는 요인으로 작용한다.In general, rainwater or groundwater permeates into concrete structures such as roof slabs, basements of buildings, or various fluid storage tanks because the waterproofing power is weak, and thus, not only lowers the self-coupling power of the concrete structure, but also changes the volume of water according to temperature changes. As a result, cracks are generated in concrete and act as a factor that shortens the life of the concrete structure.

이에, 콘크리트의 균열을 통해서 빗물이나 지하수와 같은 수분이 유입되는 것을 방지하기 위한 방수시공은 콘크리트 구조물에서 매우 중요한 위치를 차지한다.Therefore, waterproof construction to prevent the inflow of moisture such as rainwater or groundwater through cracks in concrete occupies a very important position in concrete structures.

상기 콘크리트 구조물의 방수시공은 크게 침투성 방수공법과 피막식 방수공법이 있고, 상기 침투성 방수공법은 방수제를 콘크리트 재료와 함께 혼합한 후 시공함에 따라 콘크리트 자체를 치밀하게 변화시켜 방수성능을 가지도록 하는 공법이고, 피막식 방수공법은 구조물의 내, 외부에 여러 겹의 불투수성 방수층을 형성하여 콘크리트 구조물의 균열 또는 그외 건물의 시공 결함에 대처하는 방법이다.The waterproof construction of the concrete structure is largely divided into a permeable waterproofing method and a film-type waterproofing method, and the permeable waterproofing method is a construction method in which a waterproofing agent is mixed with a concrete material and then the concrete itself is precisely changed to have waterproof performance as it is constructed. The film-type waterproofing method is a method of coping with cracks in concrete structures or other construction defects in buildings by forming multiple layers of impermeable waterproofing layers inside and outside the structure.

상기 피막식 방수공법은 불투수성 피막을 만드는 재료의 종류와 공법에 따라 도막방수, 아스팔트 방수, 시트 방수 등으로 구분된다.The film-type waterproofing method is classified into coating waterproofing, asphalt waterproofing, sheet waterproofing, and the like, depending on the type and method of the material for making the impermeable coating.

상기 도막방수는 바탕면에 프라이머층을 형성한 후 도막재를 일정두께 시공하여 방수재의 연결부분이 없이 방수층 전체를 일체화할 수 있는 것으로서, 작업의 용이성과 시공의 간편성을 가지나, 균일한 두께로 시공하기 위해서 바탕면의 평활도가 요구되고, 바탕면 균열시 방수층도 파단되는 문제점, 및 복수의 성분형 도막 방수제의 경우 정확한 배합비율을 조성하여야만 요구되는 성능을 발휘할 수 있으므로 고도의 숙련도가 요구되는 문제점이 있다.The coating waterproofing is that the entire waterproofing layer can be integrated without a connection part of the waterproofing material by applying the coating material to a certain thickness after forming the primer layer on the base surface.It has ease of work and simplicity of construction, but it is constructed with a uniform thickness. In order to do so, the smoothness of the base surface is required, the waterproof layer is also broken when the base surface is cracked, and in the case of a multi-component coating waterproofing agent, the required performance can be achieved only when the correct mixing ratio is formulated, so a high level of skill is required. have.

상기 아스팔트 방수는 지붕, 지하실, 저수탱크, 옥내방수 등에 주로 사용되는 것으로서, 구조물이 건조된 후 아스팔트 프라이머를 솔 칠 또는 스프레이 방식으로 도포하고, 그 위에 아스팔트를 녹여서 소정 두께의 방수층을 형성하한다.The asphalt waterproofing is mainly used for roofs, basements, water storage tanks, indoor waterproofing, and the like.After the structure is dried, an asphalt primer is applied by brushing or spraying, and the asphalt is melted thereon to form a waterproof layer of a predetermined thickness.

상기 시트 방수는 합성고무계, 합성수지계 등으로 이루어진 소정 두께의 방수시트를 접착제로 붙이는 방수공법으로서, 넓은 면적에 시공하기 적합하고, 신축성이 좋아 콘크리트 구조물의 균열에 대한 대응성이 있으며, 작업이 간편하다는 장점이 있다.The sheet waterproofing is a waterproofing method in which a waterproof sheet of a predetermined thickness, made of synthetic rubber, synthetic resin, etc., is attached with an adhesive.It is suitable for construction over a large area, has good elasticity, and responds to cracks in concrete structures, and the operation is simple. It has the advantage of doing it.

그러나, 종래의 시트 방수는, 일정길이와 폭을 가지는 정형화된 시트의 크기의 한계로 인해 바탕면의 크기에 따라 다수의 시트가 도포되고, 이렇게 도포된 다수의 시트들 사이에는 이음부가 형성됨으로써, 상기 이음부를 통해 수중기가 배출되거나 역으로 상기 이음부로 외부의 물이 침투되는 등과 같은 수밀안전성을 보장할 수 없음에 따라, 결국 방수성능이 저하되는 문제점이 있다.However, in the conventional sheet waterproofing, a number of sheets are applied according to the size of the base surface due to the limitation of the size of a standardized sheet having a certain length and width, and a joint is formed between the plurality of sheets thus applied, There is a problem in that watertight safety, such as discharge of water through the joint or vice versa, water-tightness safety such as penetration of external water into the joint, ultimately deteriorates waterproof performance.

이에 따라, 최근에는 도막 방수 및 시트 방수의 단점을 보완하면서 장점들에 의해 방수성능을 향상시키도록 이들을 접목시킨 복합방수공법이 사용되고 있으며, 일례를 살펴보면, 본 출원인의 선특허 제10-1884896호의 '단열시트의 2중 교차포설과 도막방수를 통한 단열성을 향상시키는 YPS구조 및 그에 따른 YPS공법'은 도 1 및 도 2에 도시된 바와 같이, 바탕면에 1차 및 2차에 걸쳐 단열시트를 포설하여 형성하는 시트층과, 상기 시트층에 일정두께의 도막재를 도포하여 도막층(20)을 이루는 구조를 포함하고, 상기 시트층은 맞댐 이음방식으로 단열시트(10)를 포설한 1차 시트층, 및 상기 1차 시트층의 이음부분인 조인트부분이 중앙에 위치되도록 단열시트(10)를 포설하여 2중 교차포설방식의 시트층이 이루어진다.Accordingly, in recent years, a composite waterproofing method in which these are combined to improve the waterproof performance by supplementing the shortcomings of the waterproofing of the coating film and the sheet waterproofing has been used. Looking at an example, the applicant's prior patent No. 10-1884896 The YPS structure that improves insulation through double-cross laying of the insulation sheet and the waterproofing of the coating film, and the YPS construction method according thereto, as shown in Figs. 1 and 2, lays the insulation sheet over the first and second stages on the base surface. And a structure in which a coating layer 20 is formed by applying a coating material of a predetermined thickness to the sheet layer, and the sheet layer is a primary sheet in which an insulating sheet 10 is installed in a butt joint method. The insulation sheet 10 is laid so that the layer and the joint portion, which is the joint portion of the primary sheet layer, is positioned at the center, thereby forming a double-cross laying method sheet layer.

또한, 상기 단열시트(10)는 발포폴리에틸렌으로 형성되는 기재부(12)와, 상기 기재부(12)의 일단에 구성되어 상기 기재부(12)에 대한 내구성을 향상시키는 보강부(14), 및 상기 기재부(12)의 타단에 구성되어 자착방식으로 시트시공이 이루어지도록 하는 점착부(16)를 포함하고, 상기 보강부(14)는 상기 기재부(12)의 일단 또는 양단 각각에서 일정길이 연장되어 조인트부분에 대한 결합력을 증가시키도록 하는 조인트보강날개(14a)를 포함한다.In addition, the heat insulating sheet 10 includes a base portion 12 formed of expanded polyethylene, a reinforcing portion 14 configured at one end of the base portion 12 to improve durability for the base portion 12, And an adhesive part 16 configured at the other end of the base part 12 to allow sheet construction in a self-adhesive manner, wherein the reinforcing part 14 is fixed at one end or both ends of the base part 12 It includes a joint reinforcing blade (14a) to extend the length to increase the coupling force to the joint portion.

또한, 상기 시트층의 조인트부분에는 건축물에 작용하는 충격 또는 진동을 흡수 및 완화시켜 단열시트(10)들에 의해 형성되는 시트층 및 도막층(20)에 대한 내구성을 향상시키도록 하는 익스펜션조인트부(30)를 포함한다.In addition, the joint portion of the sheet layer is an expansion joint that absorbs and mitigates the shock or vibration acting on the building to improve the durability of the sheet layer and the coating layer 20 formed by the insulating sheets 10. It includes part 30.

상기 익스펜션조인트부(30)는 단열시트(10)들을 일정간격으로 띄워 조인트공간(32)을 형성하며, 상기 조인트공간(32)에 안착시키고 상부에 상기 단열시트(10)의 조인트보강날개(14a)가 위치되는 익스펜션조인트브릿지(34), 및 상기 조인트공간(32)에 도막재를 중친시켜 상기 익스펜션조인트브릿지(34)에 의ㅎ 단열시트(10)와의 결합력 향상과 함께 건축물에 작용하는 충격 또는 진동을 흡수 및 완화시키도록 하는 조인트도막층(36)으로 구성된다.The expansion joint part 30 forms a joint space 32 by floating the insulating sheets 10 at regular intervals, and the joint reinforcing blades of the heat insulating sheet 10 are seated in the joint space 32 and on the upper part ( The expansion joint bridge 34 where 14a) is located, and the joint space 32 are coated with a coating material, and the expansion joint bridge 34 acts on the building with the improvement of the bonding strength with the insulation sheet 10 It consists of a joint coating layer 36 to absorb and mitigate the shock or vibration.

상술한 바와 같이, 복합방수공법의 일종인 본 출원인의 YPS공법은 단열시트를 2차 교차 포설함으로써 방수성능이 향상되는 특징이 있으나, 바탕면에 대하여 단열시트를 2차례에 걸쳐 교차 포설하여야 하는 시공의 복잡성과 2차 교차 포설에 대한 시공단가가 상승되는 문제점이 있다.As described above, the applicant's YPS method, which is a type of composite waterproofing method, has a characteristic that the waterproof performance is improved by secondly crossing the insulating sheet, but it is a construction that requires crossing the insulating sheet twice on the base surface. There is a problem of increasing the complexity of the construction and the construction cost for the second cross-laying.

또한, 시트층의 조인트부분에 대한 구조가 복잡하여 작업의 난해성으로 시공시간이 추가되는 문제점이 있다.In addition, there is a problem in that the construction time is added due to the difficulty of the operation due to the complicated structure of the joint portion of the sheet layer.
