Seam joining structure of a waterproof sheet

RYU JONG HYUN

The present invention relates to a bonding structure for a joint of waterproof sheets. The bonding structure for a joint of waterproof sheets constructs a waterproof layer by using the waterproof sheets on a concrete layer of a building. The bonding structure for a joint of waterproof sheets allows a compartment having a water-expandable water stoppage material on the joint between the waterproof sheets to be formed to prevent moisture from being introduced by damage to the bonding structure and allows a sheet overlapping area to be pressurized and closed so that the sheet overlapping area closely adheres to prevent leaking water from being additionally introduced. To this end, the bonding structure for a joint of waterproof sheets includes an overlapping band part (100), a water-expandable water stoppage material (130), and a waterproof sheet overlapping area (200).

본 발명은 방수시트의 이음부 접합구조에 관련되며, 이때 방수시트의 이음부 접합구조는 건축물의 콘크리트 층에 방수시트를 이용하여 방수층을 시공함에 있어, 방수시트간의 이음부에 수팽창지수재가 구비되는 격실이 형성되어 접합구조의 파손으로 인한 수분유입을 차단함과 동시에 시트 겹침영역이 긴밀하게 밀착되도록 가압 폐쇄시켜 누수의 추가 유입을 방지되도록 중첩띠부(100), 수팽창지수재(130), 방수시트 겹침영역(200)을 포함하여 주요구성으로 이루어진다.
