본 발명은 다양한 건축물의 방수재로 사용되는 방수시트에 관한 것으로, 특히 방수시트를 구성하는 부품과 소요자재를 최소화하여 생산원가와 공수 절감 및 생산성 향상을 구현할 수 있도록 한 방수시트에 관한 것이다.The present invention relates to a waterproof sheet used as a waterproofing material of various buildings, and more particularly, to a waterproof sheet which can realize production cost, man-hour reduction and productivity improvement by minimizing the parts and necessary materials constituting the waterproof sheet.

일반적으로 건축물의 지붕 또는 옥상에는 다양한 소재를 이용한 방수공사를 필수적으로 실시하여 눈이나 비의 실내누수를 방지하고 있음은 주지와 같으며, 근래에는 가열 용융 아스팔트 또는 접착제를 사용하는 시공방법과 자체적으로 접착성을 갖는 시트로부터 이형필름을 박리하여 시공할 수 있는 방수시트 공법이 주로 사용되고 있다.In general, it is well known that the roof or rooftop of buildings is made of waterproofing materials using various materials to prevent indoor leakage of snow or rain. The waterproof sheet method which can peel and release a release film from an adhesive sheet is mainly used.

상기 방수시트 공법에 사용되는 대표적 방수시트(S1)는 도 1 및 도 2에 예시된 바와 같이, 고중량 부직포 또는 직물, 유리섬유 등으로 선택 구성된 중심재(1)와, 상기 중심재(1)의 상하면에 1~4mm로 균일하게 열융착된 고무화 아스팔트재의 방수층(2a,2b)과, 상기 방수층(2b)의 하면에 분리가능하게 접착된 이형필름(4a)과, 상기 방수층(2a)의 상면 일측에 접착된 저중량 부직포재의 보강재(4)와, 상기 방수층(2a)의 상면 하측에 길이방향으로 접착된 이형필름(3b)으로 구성되어 있다.Representative waterproof sheet (S1) used in the waterproof sheet method, as illustrated in Figures 1 and 2, the core member (1) consisting of a high-weight non-woven fabric or fabric, glass fiber, etc., and the center member (1) of Waterproofing layers 2a and 2b of rubberized asphalt material uniformly heat-sealed 1 to 4 mm on the upper and lower surfaces, release film 4a detachably bonded to the lower surface of the waterproofing layer 2b, and the upper surface of the waterproofing layer 2a. It consists of a reinforcing material (4) of a low weight nonwoven fabric bonded to one side, and a release film (3b) bonded in the longitudinal direction below the upper surface of the waterproof layer (2a).

이와 같은 종래 방수시트(s1)는 하면의 이형필름(3a)을 제거하여 지붕 또는 옥상의 방수면에 열융착시키고, 접착된 방수시트(s1)의 상면 이형필름(3b)을 제거한 상태에서 상대측 방수시트(s1)를 겹쳐지게 적층시켜 이음부분의 방수가 이루어 지도록 시공하게 된다.Such a conventional waterproof sheet (s1) is heat-sealed to the roof or roof waterproof surface by removing the release film (3a) of the lower surface, the other side waterproof in the state of removing the upper release film (3b) of the bonded waterproof sheet (s1). By stacking the sheets (s1) to overlap, the construction is to be made waterproof.

그런데, 이러한 종래 방수시트(s1)는 시공이 쉽고 방수효과는 우수한 반면, 구성부품이 많아 소요자재와 제조공정의 추가로 인해 생산성이 저하되고 원가가 상승하게 되는 문제점 등이 지적되고 있다.By the way, the conventional waterproof sheet (s1) is easy to install and excellent in the waterproof effect, there are pointed out a problem that the productivity is lowered and the cost is increased due to the addition of the required materials and manufacturing process many components.

본 발명은 상기한 종래 기술의 문제점을 감안하여 효과적인 방수가 가능하면 서도 구조를 단순화하여 제작의 용이함과 원가절감을 적극적으로 구현함과 동시에 이동 및 보관시에 시트의 접착을 방지할 수 있는 방수시트를 제공함에 그 목적이 있다.The present invention in view of the problems of the prior art described above, while the effective waterproof is possible, while simplifying the structure to actively implement the ease of production and cost reduction and at the same time waterproof sheet that can prevent the adhesion of the sheet during movement and storage The purpose is to provide.

상기한 목적을 달성하기 위하여 본 발명에서는 중심재의 하면에 이형필름을 포함하는 방수층을 형성시키고, 중심재의 상면 일측에는 이형필름을 포함하는 접착층을 길이방향으로 형성시켜 제작과 시공의 용이함과 원가절감 및 우수한 방수효과를 얻을 수 있게 된 방수시트를 제공한다.In order to achieve the above object, in the present invention, a waterproof layer including a release film is formed on a lower surface of the center material, and an adhesive layer including a release film is formed on one side of the upper surface of the center material in a longitudinal direction, thereby facilitating production and construction and reducing costs. Provides a waterproof sheet that can obtain an excellent waterproof effect.

이하에서 상기 본 발명의 바람직한 구성 예를 첨부도면에 의해 상세히 설명한다. Hereinafter, the preferred configuration of the present invention will be described in detail by the accompanying drawings.

도 3은 본 발명에 의한 방수시트(s)의 사시도 이고, 도 4는 그 적층구성을 나타낸 것으로, 설명의 편의를 위해 종래와 동일한 부분, 부재에 대해서는 동일 부재부호를 사용하였다.Figure 3 is a perspective view of the waterproof sheet (s) according to the present invention, Figure 4 shows the laminated structure, for the convenience of description, the same parts and members as in the prior art used the same reference numerals.

본 발명 방수시트(s)는, 고중량 부직포 또는 직물, 유리섬유 등으로 선택 구성된 중심재(1)와, 상기 중심재(1)의 하면에 1~4mm로 균일하게 열융착된 고무화 아스팔트재의 방수층(2b)과, 상기 방수층(2b)의 하면에 분리가능하게 접착된 이형필름(3a)과, 상기 중심재(1)의 상면 일측에 길이방향으로 열융착된 고무화 아스팔트재의 접착층(5)과, 상기 접착층(5)의 상면에 분리 가능하게 접착된 이형필름(3b)으로 구성된다. The waterproof sheet (s) of the present invention is a water resistant layer of a rubberized asphalt material uniformly heat-sealed at a thickness of 1 to 4 mm on a lower surface of the center material 1 and a center material 1 composed of a heavy weight nonwoven fabric or fabric, glass fiber, or the like. (2b), the release film (3a) detachably bonded to the lower surface of the waterproof layer (2b), and the adhesive layer (5) of the rubberized asphalt material heat-sealed longitudinally to one side of the upper surface of the central material (1) It consists of a release film (3b) detachably bonded to the upper surface of the adhesive layer (5).

상기 중심재(1)는 적정 인장강도를 보유하는 고중량 부직포나 직물 또는 유 리섬유, 필름재 등이 사용됨은 종래와 동일 하며, 그 하면에 구비되는 방수층(2b)과 이형필름(3a)도 종래와 동일하다.The core material 1 is the same as the conventional use of a high-weight non-woven fabric or fabric or glass fiber, film material having an appropriate tensile strength, the waterproof layer (2b) and the release film (3a) provided on the lower surface is also conventional Is the same as

본 발명에서는 방수층(2b)과 이형필름(3a)을 융착 및 접착시킨 중심재(1)의 상면 일측에 적정너비, 통상 방수시트(s)의 너비가 1m임을 감안하면 10cm정도의 너비로 고무화 아스팔트를 길이방향으로 열융착시켜 접착층(5)을 형성시키고, 그 상면에 이형필름(3b)을 접착시킨 부분이 지배적 특징 부위이다.In the present invention, considering that the width of the waterproof layer (2b) and the release film (3a) is a suitable width, the width of the waterproof sheet (s) is usually 1m in consideration of one side of the upper surface of the center material (1) fused and bonded rubberized to a width of about 10cm The predominant feature is the part where the asphalt layer is heat-sealed in the longitudinal direction to form the adhesive layer 5, and the release film 3b is adhered to the upper surface thereof.

이와 같은 구성의 본 발명 방수시트(s)는 시공시에 하면의 이형필름(3a)을 제거한 후, 옥상 또는 지붕의 방수면에 방수층(2b)을 열융착 시키고, 중심재(1)의 상면 일측에 구비된 이형필름(3b)을 제거하여 접착증(5)을 노출시킨 상태에서 상대 측 방수시트(s)를 겹쳐지게 적층 시킴으로써 이음 부분의 방수도 완벽하게 이루어 지도록 설치하게 된다.The waterproof sheet s of the present invention having such a configuration removes the release film 3a on the lower surface at the time of construction, and then heat-bonds the waterproof layer 2b to the waterproof surface of the roof or roof, and one side of the upper surface of the center member 1. By removing the release film (3b) provided in the adhesive sheet (5) in the exposed state of the mating side of the waterproof sheet (s) to be superimposed to be installed so that the waterproof of the joint part is also made perfect.

이와 같이 본 발명 방수시트(s)는 중심재(1)의 상면 일부에만 고무화 아스팔트에 의한 접착증(5)이 구비되므로 종래에 비해 다량의 고무화 아스팔트를 절감할 수 있고, 또한 저중량 부직포재의 보강재(4)가 삭제되므로 구성부품 및 소요자재의 최소화에 의해 원가절감을 구현할 수 있음은 물론, 롤 형태로 권취시켜 운반 또는 보관시에 접착증(5)의 접착이 발생 되지 않으므로 제품의 불량발생도 방지할 수 있게 된다.As described above, the waterproof sheet s of the present invention is provided with the adhesion 5 due to the rubberized asphalt only on a part of the upper surface of the central material 1, so that a large amount of the rubberized asphalt can be saved compared to the conventional one, Since the reinforcement (4) is deleted, cost reduction can be realized by minimizing components and required materials, as well as adhesion of the adhesive (5) does not occur during transportation or storage by winding in a roll form. It can also prevent.

이상의 설명에서와 같이 본 발명 방수시트(s)는 구성부품과 소요자재의 최소 화에 의해 적극적인 원가절감과 생산성 향상을 구현할 수 있고, 운반이나 보관시에 불량발생의 우려가 없으며, 특히 이음 부위의 완벽한 방수효과에 의해 사용자의 제품신뢰도 및 선호도를 대폭 향상시킬 수 있는 등의 광범위한 효과가 있다.As described above, the waterproof sheet s of the present invention can realize active cost reduction and productivity improvement by minimizing components and necessary materials, and there is no fear of defects during transportation or storage, and particularly, By the perfect waterproof effect, there is a wide range of effects, such as to significantly improve the user's product reliability and preferences.
