본 발명은 지하철 및 일반 건축물의 지하실 외벽, 아파트 공동구 등 지하 콘크리트 구조물 외벽에 각종 방수재에 의해 시공된 방수층이 다른 건설시공작업이나 기타 여러가지 외부에서 가해지는 힘에 의해 방수층이 파손되는 것을 방지하기 위해 시공되는 방수층 보호시트에 관한 것으로, 더욱 상세하게는 폴리에틸렌폼의 일 면에 열을 가하여 폴리에틸렌부직포를 열융착하고, 상기 폴리에틸렌부직포가 열융착된 폴리에틸렌폼(10)의 그 이면에 접착제(30)를 국부적으로 도포하되, 상기 폴리에틸렌부직포(20) 면상에 실리콘을 도포하여 실리콘 코팅층을 구성함으로써, 폴리에틸렌폼에 폴리에틸렌부직포를 접착하여, 상기 폴리에틸렌부직포가 접착된 면이 외부로 향하도록 시공하여, 철근이나 공구에 긁힘에 의해 보호시트가 찢어지는 폐단을 방지하고, 상기 폴리에틸렌부직포의 상면에 실리콘이 도포되어 형성된 실리콘 코팅층에 의해 보호시트를 롤형태 권취 가능하고, 국부적으로 접착제를 도포함으로써, 생산원가를 절감할 수 있고, 방수층에 보호시트를 시공하기 용이하며, 시공이 간단하여 인건비 절감 및 접착면에서 발생하던 폐기물을 절감하는 방수층 보호시트 및 그 제조방법에 관한 것이다.The present invention is constructed to prevent the waterproof layer from being damaged by force applied from other construction works or other various external construction layers on the outer walls of underground concrete structures such as basement outer walls of apartments and general buildings, apartment joints, etc. It relates to a waterproof layer protective sheet, and more particularly to heat-sealing the polyethylene nonwoven fabric by applying heat to one side of the polyethylene foam, and locally attaching the adhesive 30 to the back side of the polyethylene foam 10 heat-sealed the polyethylene nonwoven fabric By applying silicone on the surface of the polyethylene nonwoven fabric 20 to form a silicone coating layer, thereby adhering the polyethylene nonwoven fabric to the polyethylene foam, and constructing the surface to which the polyethylene nonwoven fabric is bonded to the outside, Prevents the end of the protective sheet from being torn due to scratches. The silicone coating layer formed by applying silicon on the upper surface of polyethylene nonwoven fabric can roll up the protective sheet in a roll form, and by applying the adhesive locally, production cost can be reduced, and the protective sheet can be easily installed on the waterproof layer. The present invention relates to a waterproofing protective sheet and a method of manufacturing the same, which reduce labor costs and waste generated on the adhesive side.

일반적으로, 지하철, 지하차도, 전력구, 공동구, 개착식 터널등의 지하 콘크리트 구조물이나, 건물의 지하 외벽면, 지하주차장 상부 슬라브, 건물 옥상등과 같은 콘크리트 구조물에는 내부로 물이 누수되는 것을 방지하기 위하여 방수처리를 하고 있다.Generally, it prevents water from leaking into concrete structures such as subways, underground roads, electric power outlets, joint holes, and open-air tunnels, or concrete structures such as underground outer walls of buildings, upper slabs of underground parking lots, and roofs of buildings. Waterproofing is done to

방수층 외면에 방수층 보호 발포폼보드를 설치한 상태도를 각각 나타낸다.The state diagram where the waterproofing layer protection foam foam board was installed on the outer surface of the waterproofing layer is shown, respectively.

콘크리트 구조물의 면에는 콘크리트(100) 상면에 고무화 아스팔트 또는 이와 유사한 방수자재(200)로 방수시공을 한 후, 24 ∼ 30mm 두께의 보호몰탈 타설하고, 후속공정으로 누름 콘크리트를 타설하여 마감한다. The surface of the concrete structure is waterproofed with rubberized asphalt or similar waterproofing material 200 on the upper surface of the concrete 100, and then cast a protective mortar having a thickness of 24 to 30mm, and finish by pouring the pressed concrete in a subsequent process.

상부 슬라브면의 경우에는 그의 상면에 방수자재로 방수시공을 한 후, 10 ∼ 50mm 두께의 폴리에틸렌폼보드, 우레탄폼보드 또는 폴리스틸렌폼보드등의 방수층 보호재를 방수층위에 부착하고, 후속공정으로 모래 또는 흙과 돌멩이 등의 잡석이 뒤섞인 토사 되메우기 작업으로 마감을 하게 된다.In case of upper slab surface, waterproof material is installed on the upper surface of the upper slab, and then the waterproofing layer protective material such as polyethylene foam board, urethane foam board or polystyrene foam board of 10-50mm thickness is attached on the waterproof layer, and sand or soil is carried out in the subsequent process. The work is finished by refilling the earth and sand mixed with rubble and stones.

상기와 같이 지하 콘크리트 구조물의 바닥면이나 상부 슬라브면의 방수층을 보호하기 위해 24 ∼ 30mm의 방수층 보호몰탈을 타설하는 작업방법은 방수층 보호역할은 우수하나 시공 인건비가 과다하게 소요되고 시멘트 몰탈의 양생 기간 동안 후속공정의 진행이 어려운 문제점이 있다.As mentioned above, the method of placing the waterproof layer protection mortar of 24 to 30mm to protect the waterproof layer of the bottom or upper slab surface of the underground concrete structure has a good waterproof layer protection role, but the labor cost of construction is excessive, and the curing period of cement mortar While there is a problem that the progress of the subsequent process is difficult.

이러한 방수층 보호재로서 사용되는 방수층 보호몰탈 타설이나 방수층 보호 시멘트 벽돌쌓기의 문제점에 대한 대체방안으로서 최근에는 폴리에틸렌 폼보드, 우레탄 폼보드, 다소 가격이 저렴한 스틸렌 폼보드를 방수층에 부착시키되, 후속공정으로 바닥면의 경우에는 콘크리트 타설작업을 하고, 상부 슬라브면이나 벽체면의 경우에는 토사 되메우기 작업을 수행하는 방법이 사용되고 있다. 여기에서 제시한 각종 폼보드 방수층 보호재는 설치가 간편하며, 재질 자체가 소정의 탄성을 가지고 있어 충격에 대한 저항성을 널리 사용되고 있으나, 폼자체가 철근이나 공구에 훼손당하기 쉽고, 또한 철근이나 공구에 긁힘으로써, 찢어지는 문제점이 있었고, 콘크리트에 부착되는 폼보드의 면에 접착제나 이형지를 고른 도포 후 방수층 상면에 시공하였는데, 이때 폼보드의 면에 접착제나 이형지를 고른 도포함으로써, 생산원가의 비용이 많이 들뿐만 아니라, 시공이 용이하지 않고 또 시공 후 수정 시공이 용이하지 않았다.As an alternative to the problems of the waterproof layer protection mortar casting or waterproof layer protection cement racking used as the waterproof layer protection material, recently, polyethylene foam board, urethane foam board, and inexpensive styrene foam board are attached to the waterproof layer. In case of cotton, concrete pouring works are performed, and in the case of upper slab surfaces or wall surfaces, soil refilling is used. The various foam board waterproofing layer protection materials presented here are easy to install, and the material itself has a certain elasticity so that it is widely used for resistance to impact, but the foam itself is easily damaged by reinforcing bars or tools, and also scratches on rebars and tools. As a result, there was a problem of tearing, and evenly applied adhesive or release paper on the surface of the foam board to be attached to the concrete and then installed on the upper surface of the waterproof layer. In addition, the construction was not easy and the modification after the construction was not easy.

그리고 이형지에서 발생하는 폐기물을 제거하는 것도 용이하지 않았으며, 폐기물량도 많이 발생하는 문제점이 있었다.And it was not easy to remove the waste generated from the release paper, there was a problem that also generates a lot of waste.

따라서 본 발명은 종래에서 상기한 제반 문제점을 해소하기 위해 폴리에틸렌폼에 폴리에틸렌부직포를 접착하여, 상기 폴리에틸렌부직포가 접착된 면이 외부로 향하도록 시공하여, 철근이나 공구에 긁힘에 의해 보호시트가 찢어지는 폐단을 방지하고, 상기 폴리에틸렌부직포의 상면에 실리콘이 도포되어 형성된 실리콘 코팅층에 의해 보호시트를 롤형태 권취 가능하고, 국부적으로 접착제를 도포함으로써, 생산원가를 절감할 수 있고, 방수층에 보호시트를 시공하기 용이하며, 시공이 간단하여 인건비 절감 및 접착면에서 발생하던 폐기물을 절감하고, 또한 방수층 시공 후 상기 방수층 보호재 설치후 와이어 메쉬 또는 철근 배근작업시에도 방수층의 파손우려가 없고, 벽체면 방수층위에 설치하였을 경우에는 방수층 보호재의 표면이 매끄럽게 형성되어 있기 때문에, 토사의 되메우기 작업이 용이한 방수층 보호시트 및 그 제조방법을 제공함을 그 목적으로 하고 있다.Therefore, in the present invention, in order to solve the above-mentioned problems, the polyethylene nonwoven fabric is adhered to the polyethylene foam, and the surface to which the polyethylene nonwoven fabric is bonded is directed to the outside, so that the protective sheet is torn by scratching the rebar or the tool. By preventing the closed end, the protective sheet can be rolled up by the silicone coating layer formed by applying the silicone on the upper surface of the polyethylene nonwoven fabric, and by applying the adhesive locally, the production cost can be reduced, and the protective sheet is constructed on the waterproof layer. Easy to install, simple construction reduces labor costs and waste generated on the adhesive surface, and after installing the waterproofing layer, there is no fear of damage of the waterproofing layer even when wire mesh or reinforcement works after installing the waterproofing layer protective material, and installed on the waterproofing layer of the wall surface In this case, the surface of the waterproofing layer protective material is smoothly formed. , Has a waterproof layer providing a protective sheet and a method of manufacturing an easy backfilling operation of earth and sand for that purpose because.
