Description

자착식 비노출 복합방수구조{Non exposure multiple waterproofing system}Non exposure multiple waterproofing system

본 발명은 자착식 비노출 복합방수구조에 관한 것으로서, 더욱 상세하게는, 바탕면에 방수시트를 도포한 방수시트층 및 도막재를 도포한 도막층으로 구성되고, 상기 방수시트층을 이루는 방수시트들을 일정간격 띄움시켜 형성된 이음공간에 발포시트를 도포한 비노출 방수구조를 채택함으로써, 방수시트층에 의한 1차 방수 및 도막층에 의한 2차 방수로 방수성능을 향상시키고, 방수시트층의 발포시트를 도포하여 상기 방수시트가 외부환경요인에 의해 신축작용이 이루어져도 탄력적으로 작용하여 방수시트의 부착상태를 유지할 수 있도록 하여 방수성능과 부착성을 향상시키는 자착식 비노출 복합방수구조에 관한 것이다.The present invention relates to a self-adhesive non-exposed composite waterproof structure, and more particularly, to a waterproof sheet layer coated with a waterproof sheet on the base surface and a coating layer coated with a coating material, the waterproof sheets forming the waterproof sheet layer By adopting the non-exposed waterproof structure that coated foam sheet on the joint space formed by spaced interval, the waterproof performance is improved by the first waterproof by the waterproof sheet layer and the second waterproof by coating layer, and the foam sheet of waterproof sheet layer is applied. The waterproof sheet is a self-supporting non-exposed composite waterproof structure to improve the waterproofing performance and adhesion by maintaining the attachment state of the waterproof sheet by elastically acting even if the elastic sheet is made by the external environmental factors.

일반적으로, 건축 구조물의 방수는 건축 총 공사비의 1 ~ 3% 이하로 금액적인 측면에서는 미비한 부분을 차지하고 있으나, 실거주자의 쾌적한 주거 환경의 유지라는 환경적인 측면뿐만 아니라 누수로 인한 철근 및 철골의 부식, 중성화, 동결융해, 유해 물질의 침입 등으로 인한 구조적인 열화가속화 등 내구성 저하의 방지 차원에서 영향력이 큰 중요한 공정이다.In general, the waterproofing of building structures is less than 1 ~ 3% of the total construction cost, which is insignificant in terms of money, but corrosion of reinforcing steel and steel due to leakage as well as environmental aspects of maintaining a comfortable living environment for real residents. It is an important process that has a high impact in order to prevent durability deterioration such as structural deterioration acceleration due to neutralization, freezing thawing and invasion of harmful substances.

건축물의 방수에 사용되는 비노출 방수공법은 노출방수공법 시공 단가의 약 50% 수준에서 시공이 가능한 공법으로 국내 옥상방수공법의 70%를 점유하고 있다.The non-exposed waterproof method, which is used for waterproofing the building, can be constructed at about 50% of the unit price of the exposed waterproof method and occupies 70% of the domestic rooftop waterproof method.

한편, 콘크리트 구조물의 방수공법으로는 침투성 방수공법과, 피막식 방수공법으로 나눌수 있고, 상기 침투성 방수공법은 방수제를 콘크리트 표면에 도포하여 콘크리트 자체를 치밀하게 변화시켜 방수성을 높이는 방법이고, 피막식 방수공법은 콘크리트 구조물의 내, 외부에 여러 겹의 불투수성 방수층을 형성하여 콘크리트 구조물의 균열 또는 그 외 건축물의 시공 결함에 대처하여 방수성을 높이는 방법이다.On the other hand, the waterproofing method of the concrete structure can be divided into a permeable waterproof method and a film-type waterproof method, the permeable waterproof method is a method of increasing the waterproofness by applying a waterproofing agent to the concrete surface to change the concrete itself, the film-type waterproof The construction method is a method of improving water resistance by forming multiple layers of impermeable waterproof layers inside and outside of a concrete structure to cope with cracks in concrete structures or construction defects of other buildings.

상기 피막식 방수공법은 아스팔트 방수, 시트방수, 도막방수 등으로 구분되며, 방수효과를 높이기 위하여 최근에는 도막재와 시트를 함께 시공하는 복합방수공법이 사용되고 있다.The coating type waterproofing method is divided into asphalt waterproofing, sheet waterproofing, waterproofing coating, etc. Recently, in order to increase the waterproofing effect, a composite waterproofing method for constructing a coating material and a sheet together is used.

상기 시트방수는 아스팔트 루핑, 개량아스팔트 방수시트, 합성고분자계 방수시트, 자착식 고무화 아스팔트 방수시트, 점착 유연형 방수시트 등이 있다.The sheet waterproofing includes asphalt roofing, improved asphalt waterproof sheet, synthetic polymer waterproof sheet, self-adhesive rubberized asphalt waterproof sheet, adhesive flexible waterproof sheet.

상기 개량 아스팔트 방수시트는 180℃ 이상의 고온의 아스팔트에 스티렌-부타디엔-스티렌(SBS) 중합체를 융해시킨 후 각종 첨가제를 혼합하여 아스팔트가 가질 수 없는 성질, 즉, 우수한 내열성, 내화학성, 내한성 및 접합성 등을 가지도록 개질시킨 것으로 부직포 등의 중심기재를 사용하여 일정한 두께로 정형화시킨 방수시트이다.The improved asphalt waterproof sheet melts the styrene-butadiene-styrene (SBS) polymer on high-temperature asphalt of 180 ° C. or higher, and then mixes various additives to prevent asphalt from having properties, that is, excellent heat resistance, chemical resistance, cold resistance, and bonding properties. It is modified to have a waterproof sheet that is shaped to a certain thickness using a central base such as a nonwoven fabric.

상기 개량 아스팔트 방수시트는 내열성, 내화학성, 내한성 및 접합성이 우수한 장점이 있으나, 시트의 형태로 정형화하기 위해 중심기재를 중심으로 상부와 하부에 일정두께의 개질아스팔트층을 형성하는 데, 이는 하부 또는 상부에 유기용제가 함유된 도막방수제가 복합적으로 시공될 경우 시트 변형이나 개질아스팔트층의 용해의 원인으로 작용하여 방수층을 파괴하는 문제점이 있다.The improved asphalt waterproof sheet has the advantages of excellent heat resistance, chemical resistance, cold resistance and bonding, but to form a sheet-like modified asphalt layer having a predetermined thickness on the top and bottom centering the center substrate, which is the bottom or When the coating film waterproofing agent containing the organic solvent on the top is combined, there is a problem of breaking the waterproof layer by acting as a cause of sheet deformation or dissolution of the modified asphalt layer.

종래의 아스팔트 방수시트의 일례를 살펴보면, 선등록 특허 제10-1681001호의 복합방수용 개질아스팔트 펠트시트는, 글라스 파이버 메취 중심층, 및 상기 글라스 파이버 메쉬 중심층 상, 하부로 장섬유 또는 단섬유 부직포로 구성된 아스팔트 펠트 원지에 개질아스팔트를 함침하는데, 상기 개질아스팔트는 스트레이트 아스팔트 100중량부에 SBS, SIS, SERS, SBR의 합성고무 5 ~ 20 중량부, 아스팔트 중온 혼화제 1 ~ 5 중량부가 혼합된 것을 특징으로 하며, 상기 아스팔트 펠트 원지에 개질아스팔트를 제조설비로 함침한 후 탈유하여 제조하는 것을 특징으로 하며, 펠트시트 제조공정은 140 ~ 170℃에서 제조되어 아스팔트의 가스 및 흄 발생을 억제하는 것이다.Looking at an example of a conventional asphalt waterproof sheet, the composite waterproof modified felt felt sheet of the pre-registered Patent No. 10-1681001, the glass fiber mesh center layer, and the glass fiber mesh center layer, the bottom of the long fiber or short fiber nonwoven fabric It is impregnated with modified asphalt on the asphalt base material, wherein the modified asphalt is mixed with 100 parts by weight of straight asphalt, 5 to 20 parts by weight of synthetic rubber of SBS, SIS, SERS, and SBR, and 1 to 5 parts by weight of an asphalt moderate temperature admixture. In addition, the asphalt felt base paper is characterized in that it is produced by impregnating the modified asphalt with a manufacturing facility and then deoiled. The felt sheet manufacturing process is manufactured at 140 to 170 ° C. to suppress the generation of asphalt gas and fumes.

그러나, 상기 개량아스팔트 방수시트는 개량 아스팔트 열공법 등이 주로 사용되면서 냄새로 인한 환경오염, 민원발생, 토치 및 열풍기 사용으로 인한 전문인력 요구, 열이 과도하게 전달되었을 때 재료의 손상 및 변형부착 또는 바탕면과의 부착력 약화 등을 야기하는 문제점이 있다.However, the improved asphalt waterproof sheet is mainly used as an improved asphalt thermal method, environmental pollution due to odors, civil complaints, demands of professional personnel due to the use of torch and hot air blower, damage or deformation of materials when heat is excessively transferred or There is a problem that causes a weakening of the adhesion with the base surface.

이에, 자착식 아스팔트 시트가 사용되고 있으며, 상기 자착식 아스팔트 시트는, 시트 후면에 자체 점착성을 부여하여 바탕면에 부착하는 방식으로 사용함에 따라 접착력이 기존 열공법을 이용한 아스팔트 공법에 비해 낮고, 바탕면의 상태 즉, 레이턴스의 처리상태, 요철, 습윤상태 등에 따라 접착성능의 변동폭이 크다는 문제점이 있다.Therefore, the self-adhesive asphalt sheet is used, the self-adhesive asphalt sheet, the adhesive strength is lower than the conventional asphalt method using the conventional thermal method, by using a method of attaching to the base surface by attaching itself to the back of the sheet, In other words, there is a problem in that the variation in adhesion performance is large depending on the state of the treatment, the irregularity, the wet state, and the like.

또한, 종래의 다른 일례를 살펴보면, 도막재와 개질아스팔트 시트를 이용한 비노출복합공법은, 특허 제10-638990호에 게시된 우레탄과 양면 부직포 형태의 냉공법과, 공개특허 제10-2000-2469호에 게시된 사용성을 높이도록 아스팔트계의 도막재와 개질아스팔트 시트의 하층부에 부직포를 부착하고 상측부에 PE필름을 부착하며 양면에 아스팔트 컴파운드가 도포된 합성수지재가 개제되어 있는 매스틱 도막시트 이중방수공법이다.In addition, referring to another conventional example, the non-exposure composite method using the coating material and the modified asphalt sheet includes a cold working method in the form of a urethane and a double-sided nonwoven fabric disclosed in Patent No. 10-638990, and Patent Publication No. 10-2000-2469. Mastic coating sheet double waterproofing method with non-woven fabric attached to the lower layer of asphalt-based coating material and modified asphalt sheet, PE film attached to the upper side, and synthetic resin material coated with asphalt compound on both sides to improve usability posted on to be.

그러나, 매스틱 방수의 경우에 용제형의 아스팔트 컴파운드가 기존 우레ㅏㄴ 같은 액상에 비해 점도가 많이 높아 도포작업이 힘들어 작업의 효율이 떨어지며 겔상태의 아스팔트 컴파운드가 굳는 현상이 발생되어, 콘크리트의 균열에 대한 추종성을 지속적으로 기대하기는 어려우며, 조인트 연결부위 역시 바닥 도포용의 용제형 아스팔트 컴파운드를 사용하고 있어, 이질재료로 수밀한 복합화 형성이 어려우며 용제형의 아스팔트 컴파운드라 결국, 용제가 휘발되어 일정시간이 경과하에 되면 딱딱하게 굳어져 도막재의 탄성과 인장강도 등이 미약하게 되어 이음부 파단 위험성이 존재한다.However, in the case of mastic waterproofing, the solvent-type asphalt compound has a higher viscosity than the existing liquid such as urethane, so that the coating work is difficult and the work efficiency decreases, and the gel-like asphalt compound is hardened. It is difficult to continuously expect follow-up, and joint joints also use solvent-based asphalt compounds for floor application, making it difficult to form water-tight complexes with dissimilar materials, and solvent-based asphalt compounds. Under this time, it hardens, and the elasticity and tensile strength of the coating material become weak, resulting in the risk of fracture of the joint.

따라서, 이러한 자착식 시트와 복합공법의 문제점을 보완하고 자재를 정량시공하면서, 미숙련자도 쉽게 시공할 수 있고, 다양한 콘크리트 구조물과 기후 변화, 현장 여건이나 시공자의 선호도에 따라 선택적으로 적용될 수 있으면서, 탁월한 방수성능을 발휘하도록 하는 도막재 개발과 이를 이용한 복합방수공법의 개발이 매우 중요하다.Therefore, while compensating for the problems of the self-adhesive sheet and composite method and quantitatively constructing materials, even unskilled workers can be easily constructed, and can be selectively applied according to various concrete structures, climate change, site conditions, or preferences of the builder, It is very important to develop a coating material to exhibit waterproof performance and to develop a composite waterproof method using the same.
