본 발명은 우레탄, 에폭시계의 도막 방수의 경량콘크리트나 보호몰탈의 시공 후 1-2년이 경과되면 콘크리트층 또는 몰탈 자체에 함유된 수분으로 인하여 도막방수층이 들뜨거나 박리현상이 발생되는 것을 미연에 방지하므로서 방수 및 단열의 효과가 우수하도록 하기 위하여 몰탈이나 콘크리트층에 함유된 습기의 배출과 환기를 유도할 수 있게 하는 것을 목적으로 하는 습기의 배출 및 환기유도가 가능하게 한 콘크리트 바닥의 시공방법에 관한 것이다.In the present invention, after 1-2 years of construction of lightweight concrete or protective mortar of urethane and epoxy coating waterproofing, the coating layer waterproof layer is lifted or peeling occurs due to moisture contained in the concrete layer or mortar itself. In order to prevent the moisture and insulation contained in the mortar or concrete layer in order to improve the effect of waterproofing and insulation by preventing it, It is about.

지금까지 알려진 도막방수의 시공방법은 우레탄이나 에폭시계에 의한 도착방법이었는 바, 이는 시공후 1-2년이 경과되면 그 대부분이 콘크리트층이나 몰탈 자체에 함유된 수분으로 인하여 도막방수층이 들뜨거나 박리현상이 발생되어 국부적 또는 전면적으로 보수작업을 실시해야 하는 번거로움과 시공비의 낭비가 있었다.Until now, the construction method of waterproofing coating film has been urethane or epoxy-based arrival method, which is one or two years after construction, and most of them are lifted or peeled off due to moisture contained in concrete layer or mortar itself. The phenomenon occurred and wasted the hassle and construction cost to perform maintenance work locally or entirely.

본 발명은 상기와 같은 문제점을 해소하기 위하여 콘크리트층 상부로 공극부위를 형성하여 콘크리트층이나 몰탈에 함유되는 수분을 공기중으로 배출시킬 수 있게 하므로서 도막방수층의 수명을 장구하게 한것으로 이를 첨부된 도면에 의한 실시예에 의하여 상세히 설명하면 다음과 같다.The present invention is to form a void portion in the upper concrete layer to solve the above problems by allowing the moisture contained in the concrete layer or mortar to be discharged into the air to ensure the longevity of the waterproof layer according to the accompanying drawings When described in detail by the embodiment as follows.

(제1공정:바탕처리작업공정)(1st process: background treatment work process)

시공된 베이스 슬라브 콘크리트(1) 또는 보수하고자 하는 베이스 슬라브 콘크리트(1)의 표면을 깨끗이 청소하면서 파지작업을 행한 후 바탕고름몰탈(2)과 에폭시 등의 방수액체를 혼합하여 슬라브 콘크리트(1)의 파손부위와 취약부분을 보완할 수 있도록 바탕처리작업을 행하여 바탕고름몰탈(2)의 두께가 약 20mm이상이 되도록 한다.After holding and cleaning the surface of the constructed base slab concrete (1) or the base slab concrete (1) to be repaired, the base pubic mortar (2) and a waterproofing liquid such as epoxy are mixed to make the slab concrete (1) In order to make up the damaged part and the weak part, the background treatment is carried out so that the thickness of the ground pulp mortar (2) is about 20 mm or more.

(제2공정:공극부위의 형성작업공정)(Second process: forming work process of void part)

제1공정의 바탕처리작업이 끝나면 바탕고름몰탈(2)의 바닥면을 다이아몬드 커터 등으로 가로부분 및 세로부분을 5m 정도의 간격을 띠어 폭을 약 10mm, 깊이 약 10mm 정도로 홈을 파내어 공극부위(3)를 형성한다.After the ground treatment work of the first process is finished, the bottom surface of the pus mortar (2) is spaced about 5m in the horizontal and vertical sections with a diamond cutter, etc., and the grooves are dug about 10mm in width and 10mm in depth. 3) form.

그리고 가로, 세로부분에 일정간격으로 각각 형성된 공극부위(3)의 끝단부와 벽체(10)가 만나는 부위에서부터 일정높이까지는 상부가 절곡된 통기용 파이프(7)가 삽입이 가능한 요홈부를 미리 형성하였다가 그 요홈부에 통기용 파이프(7)를 삽입 고정시켜 공극부위(3)와 통기용 파이프(7)의 내측 공간이 상호 연결되도록 하고 요홈부와 통기용 파이프(7) 사이의 공간은 보호몰탈과 에폭시 등의 방수액체를 혼합시킨 것으로 채운다.In addition, the grooves for inserting the aeration pipe 7 bent in the upper part from the site where the end portions of the gap portions 3 formed at predetermined intervals on the horizontal and vertical portions and the wall 10 meet at a predetermined height are formed in advance. Insert and fix the ventilation pipe (7) in the recess so that the inner space of the air gap (3) and the ventilation pipe (7) are interconnected, and the space between the groove and the ventilation pipe (7) is a protective mortar Fill it with a mixture of water-resistant liquids such as epoxy.

또한 기본 설치 건물에 통기용 파이프(7)를 설치할 때에는 통기용 파이프(7)가 설치될 벽체(10)를 정과 함마 등을 이용하여 인위적으로 통기용 파이프(7)를 매설시키고 요홈부와 통기용 파이프(7)사이의 공간은 보호몰탈과 에폭시등의 방수 액체를 혼합한 것으로 채운다.In addition, when installing the ventilation pipe (7) in the basic installation building artificially buried the ventilation pipe (7) by using a chisel and a hammer on the wall (10) on which the ventilation pipe (7) will be installed, The space between the pipes 7 is filled with a mixture of a protective mortar and a waterproofing liquid such as epoxy.

이때 통기용 파이프(7)의 상단 절곡부(7)는 설치되는 벽체(10)에서 노출되도록 하고 상단 절곡부(7')의 노출방향은 옥상이나 실내 바닥면의 구조에 따라 통기가 가능한 방향이면 무방하다.At this time, the upper bent portion 7 of the ventilation pipe 7 is exposed at the wall 10 to be installed, and the exposure direction of the upper bent portion 7 'is a direction allowing ventilation according to the structure of the rooftop or the indoor floor. It's okay.

(제3공정:마무리 공정)(3rd step: finishing step)

공극부위(3)상부를 몰탈면과 일직선상이 되도록 공극부위를 트랜치 형식으로 하여 플라스틱 바(BAR)(4)로 덮은 다음 에폭시 접착제를 도포하여 접착제층(5)을 형성하고 응결되기 이전에 마스킹테이프(6)를 골고루 부착한 후 기포 또는 핀홀을 제거하면서 다시 공지의 방법에 의해 상기의 에폭시 접착제를 도포하여 접착제층(5')을 형성케 한 다음 그 상부를 경량콘크리트(8)층과 우레탄 방수재를 도착시킨 방수층(9)을 순차적으로 형성하고 보호몰탈(2')로 마감한다.Cover the voids with a plastic bar (BAR) 4 in the form of a trench so that the upper part of the voids is in line with the mortar surface, and then apply an epoxy adhesive to form an adhesive layer 5 and masking tape before condensation. After attaching evenly to (6), remove the bubble or pinhole and apply the above-mentioned epoxy adhesive again by a known method to form an adhesive layer (5 '), and then the upper part of the lightweight concrete (8) layer and urethane waterproofing material. Forming the waterproof layer (9) to arrive in sequence and finishes with a protective mortar (2 ').

여기에서 접착제층(5') 상부에 형성시키는 경량콘크리트(8)층과 방수층(9)은 설치장소의 여건에 따라 그 상호 순서를 바꾸어도 본 발명에서 얻을 수 있는 효과는 거의 동일하다.Here, even if the light-weight concrete layer 8 and the waterproof layer 9 formed on the adhesive layer 5 'are changed in order depending on the installation location, the effect obtained in the present invention is almost the same.

상기의 작업으로 본 발명의 모든 공정은 완료되는데 접착제층(5)(5')을 형성케하는 에폭시 접착제는 상표명 포리크릿트-이(POLYCRETE-E)[주식회사 코리아코팅엔지니어링 제품]을 사용하였고 우레탄 방수제는 상표명 케이.씨.유.티(K.C.U.T) 또는 포리크릿트-유(POLYCRETE-U)[이상 주식회사 코리아코팅엔지니어링 제품]을 사용하여 코팅을 하였으며 접착제층(5') 상부로 타설시키는 경량콘크리트는 경량, 환기, 단열의 효과가 우수한 것[예:상표명 아스통(ASTONG)](주식회사 코리아코팅엔지니어링 제품)을 사용하는 것이 좋으며 여건에 따라 보호몰탈로 마감하게 되면 슬라브 콘크리트(1)의 바탕에 스며든 수분이 있었더라도 그 수분이 공극부위(3)로 모여 통기용 파이프(7)를 통하여 환기가 이루어져 공극부위(3)가 자연 건조되었음을 알 수 있었으므로 도막방수와 단열의 효과가 우수하고 바닥라이닝이 가능하게 되는 지대한 효과가 있는 유용한 발명인 것이다.All the processes of the present invention are completed by the above operation, and the epoxy adhesive for forming the adhesive layer (5) (5 ') uses POLYCRETE-E (Korea Coating Engineering Co., Ltd.). The waterproofing agent was coated using the brand name KCUT or POLYCRETE-U (above Korea Coating Engineering Co., Ltd.) and lightweight concrete that is poured on top of the adhesive layer (5 '). It is recommended to use lightweight, ventilated, and insulated products (e.g., `` ASTONG '') (Korea Coating Engineering Co., Ltd.). Even though there was moisture, the moisture gathered into the air gap (3) and the air was vented through the ventilation pipe (7), indicating that the air gap (3) was naturally dried. It is a useful invention that has a great effect that the effect is excellent and the floor lining is possible.
