Description
본 발명은 건축 구조물용 부분절연식 복합 방수구조 및 그 방수공법에 관한 것으로, 좀 더 구체적으로는 방수시트 및 도막방수재를 이용한 복합 방수층을 바탕면에 접착시킴에 있어서 부분절연 접착방식을 이용하여, 응력 집중으로 인한 방수층의 균열 및 방수 시트의 접착력 약화로 인한 들뜸 현상을 방지하고, 거동 대응성, 충격 저항성 및 진동 흡수성이 우수한 건축 구조물용 부분절연식 복합 방수구조 및 그 방수공법에 관한 것이다.The present invention relates to a partially insulating composite waterproof structure for a building structure and a waterproofing method thereof, and more particularly, by using a partial insulating adhesive method in bonding a composite waterproof layer using a waterproof sheet and a film waterproofing material to a base surface, The present invention relates to a partially insulated composite waterproof structure for building structures which prevents the cracking of the waterproof layer due to stress concentration and the lifting phenomenon due to the weakening of the adhesive force of the waterproof sheet, and has excellent behavior response, impact resistance and vibration absorption, and a waterproofing method thereof.
건축 구조물에 대한 방수공법으로서 종래 알려진 것으로는 아스팔트 방수, 시멘트 액체 방수, 도막방수, 시트방수 등이 있다. 이 중 도막방수는 합성고무나 합성수지 및 경화제를 혼합하여 바닥층에 밀착 도포함으로써 형성된 도막을 통해 방수 효과를 얻도록 하는 것으로, 충격 저항성 및 마모 저항성은 우수하지만 외부 진동에 대한 흡수성이 미약하고 들뜸 현상이 일어날 수 있다는 단점을 갖는다. Conventionally known as waterproofing method for building structures include waterproofing asphalt, waterproofing cement liquid, waterproofing coating, sheet waterproofing and the like. Among these, the waterproof film is obtained by mixing synthetic rubber, synthetic resin, and hardening agent and applying it to the bottom layer to obtain waterproof effect. It has excellent impact resistance and abrasion resistance, but has low absorbency against external vibration and lifts up phenomenon. Has the disadvantage that it can happen.
또한 시트방수는 합성고무나 합성수지 또는 고무화 아스팔트 등을 주원료로 하여 일정 규격의 방수시트를 연결함으로써 방수 효과를 얻도록 하는 것으로서, 초기에는 아스팔트 방수시트들 간의 이음부를 결합시키기 위하여 이웃하는 양 아스팔트 시트의 이음부를 겹친 다음 토오치 램프 등을 사용하여 용융시켜 부착하는 방법이 사용되었다. 그러나, 이음부에 대한 토오치 램프의 과열 또는 불완전한 가열로 인하여 누수 발생의 원인이 되기도 하였으며, 단지 시트방수재의 자기접착만으로 프라이머가 도포된 하부와 접착되었기 때문에, 콘크리트면과 방수층간의 들뜸 현상이 발생하여 차후 하자 발생시 누수 부위를 찾기가 용이하지 않다는 문제점이 있었다. In addition, the sheet waterproofing is to obtain a waterproofing effect by connecting a waterproof sheet of a certain standard using synthetic rubber, synthetic resin, or rubberized asphalt as a main raw material, and initially neighboring both asphalt sheets to join the joints between the asphalt waterproof sheets. The method of overlapping the joints of and then melting and attaching using a torch lamp or the like was used. However, overheating or incomplete heating of the torch lamps to the joints may cause leakage, and only the self-adhesiveness of the sheet waterproofing material adheres to the primer-coated lower part, causing the phenomenon of lifting between the concrete surface and the waterproof layer. There was a problem that it is not easy to find the leakage site when the defect occurs later.
따라서 최근에는 아스팔트 시트방수와 도막방수의 단점을 개선한 복합방수공법이 개발되었다. 이러한 예는 국내 특허 제180632호(1998. 12. 2 등록) 및 특허 제337618호(2002. 5 9 등록)가 있다. 이들은 콘크리트 바닥면 위로 프라이머를 도포하거나 또는 도포하지 않고 아스팔트 방수시트를 바닥면에 밀착시키며, 인접하는 방수시트들 사이의 견실한 접착을 위해 경화성 합성수지액을 도포하거나, 방수시트 본체 위로 부직포 변위부를 형성하여 인접하는 방수시트 자체를 일부 중첩시키면서 부직포 변위부를 밀봉제를 이용하여 인접하는 방수시트에 접착되도록 하였다.Therefore, in recent years, a composite waterproofing method has been developed that improves the disadvantages of asphalt sheet waterproofing and coating waterproofing. Examples of this are Korean Patent No. 180632 (registered on December 2, 1998) and Patent No. 37618 (registered on May 9, 2002). They adhere the asphalt waterproof sheet to the floor with or without primer on the concrete floor, apply a curable synthetic resin solution for strong adhesion between adjacent waterproof sheets, or form a nonwoven displacement over the waterproof sheet body. The non-woven fabric displacement part was bonded to the adjacent waterproof sheet using a sealant while partially overlapping the adjacent waterproof sheet itself.
그러나 이러한 종래의 복합방수공법에 의할 경우, 인접하는 시트와 시트 접착시 방수재 사이의 높이차로 인하여 차후에 물고임 현상이 발생할 수 있었으며, 인접 시트들의 접착을 위해 별도의 합성수지액을 준비하여야 하거나 2중 접착 구조를 취함으로써 부착시공작업상의 작업성 및 경제성이 떨어졌다.However, according to the conventional composite waterproofing method, the water pooling phenomenon may occur later due to the height difference between the adjacent sheet and the waterproofing material when the sheet is bonded, and a separate synthetic resin solution should be prepared for the adhesion of the adjacent sheets or double By adopting the adhesive structure, workability and economical efficiency of the attaching and construction work were deteriorated.
이러한 종래 기술의 문제점을 극복하기 위하여 본원 발명자는 2003. 10. 9자로 출원된 국내 특허출원 제2003-70202호 "방수시트를 이용한 복합 방수구조 및 방수공법"에서, 콘크리트층 또는 아스팔트 프라이머층 위로 도포되는 도막방수재; 상기 도막방수재의 상부에 배치되며 고무화 아스팔트층을 사이에 둔 상하 부직포층으로 구성된 제 1 방수시트; 상기 제 1 방수시트와 2-15mm 간격을 두고 배치되며 고무화 아스팔트층을 사이에 둔 상하 부직포층으로 구성된 제 2 방수시트; 및 상기 상부 또는 하부 부직포층의 일끝단 또는 양끝단으로 5-10cm 연장된 부직포 이음부로 구성되며, 상기 방수시트들 사이의 간격에 상기 도막방수재와 동일 재질의 틈도막방수재가 채워지고, 상기 부직포 이음부의 일부가 인접하는 상기 방수시트의 상기 부직포층과 중첩하여 접합되는 것을 특징으로 하는 방수 시트를 이용한 복합 방수구조 및 방수공법을 개시하였다. 이는 방수시트 자체 및 방수시트의 부직포 이음부와 도막재 사이의 일체 결합을 도모하여 방수층의 수밀성을 확보하고, 방수재 사이의 높이차로 인한 물고임 현상을 방지하며, 접착제를 사용하지 않음으로써 경제성과 작업성을 도모할 수 있는 유용한 방수공법이다.In order to overcome the problems of the prior art, the present inventors apply to the concrete layer or asphalt primer layer in Korean Patent Application No. 2003-70202, "Compound waterproof structure and waterproofing method using a waterproof sheet", filed October 9, 2003. Coating waterproofing material; A first waterproof sheet disposed on an upper portion of the coating waterproof material and configured of an upper and a lower non-woven fabric layer having a rubberized asphalt layer therebetween; A second waterproof sheet disposed at a distance of 2-15 mm from the first waterproof sheet and configured of an upper and a lower non-woven fabric layer having a rubberized asphalt layer therebetween; And a non-woven fabric joint portion extending 5-10 cm to one or both ends of the upper or lower nonwoven fabric layer, wherein the gap between the waterproof sheets is filled with a gap coating waterproof material of the same material as the coating waterproof material, and the nonwoven fabric joint A composite waterproof structure and a waterproofing method using a waterproof sheet are disclosed, wherein a portion of the portion overlaps and joins the nonwoven layer of the adjacent waterproof sheet. This ensures the watertightness of the waterproof layer by preventing the watertightness due to the difference in height between the waterproof sheet itself and the nonwoven fabric joints of the waterproof sheet and the coating material, and prevents water sticking due to the height difference between the waterproof materials. It is a useful waterproofing method to promote sex.
한편, 건축 구조물에 외부 충격이 지속적으로 가해지거나 환경 조건의 변화 등으로 인하여 응력이 가해질 경우 방수층은 지속적인 거동으로 균열이 발생할 수 있으며, 균열이 진행되어 방수층이 파단되면 누수가 발생하여 구조물이 열화되고, 최악의 경우 구조물을 철거하거나 재건설하여야 하는 상황에도 이를 수 있다. On the other hand, if a stress is applied due to a continuous external impact or a change in environmental conditions, the waterproof layer may crack due to continuous behavior.If the crack progresses and the waterproof layer breaks, leaks may occur and the structure deteriorates. In the worst case, this can lead to the need to demolish or rebuild the structure.
따라서 본 발명자는 종래의 복합방수공법의 문제점을 극복하고 지속적 거동이나 환경 조건의 변화에 대하여도 안정적인 보다 개선된 방수공법을 연구한 결과, 본 발명을 완성하게 되었다.Therefore, the present inventors have overcome the problems of the conventional composite waterproofing method, and as a result of researching a more improved waterproofing method that is stable against continuous behavior or changes in environmental conditions, the present invention has been completed.

Another object of the present invention is to use a separate weaving network type reinforcement for the bonding of the adjacent sheet and the sheet when the butt joint, without the use of an adhesive in the connection between the adjacent waterproof sheet requires a sealing operation By not doing so, it is to provide a partially insulating composite waterproof structure and a waterproofing method for building structures, which is more workable and economical.
