Description
본발명은 층간조인트 크랙 방지 방법에 관한 것으로, 보다 상세하게는 층간 조인트 상부 면에 인위적으로 홈을 설치하여 크랙을 유도하고 그 홈을 외부용 코킹제를 채움으로 크랙 퍼티제의 박리에 따른 누수 현상을 억제하고 추후 변형 발생시 코킹제 만 재시공하여 크랙에 대한 하자 처리를 최소화 하며, 또한 골조공사 시 조인트 줄눈 설치 및 면처리에 의해 도장공사전 코킹제 시공으로 단순화 하여 시공비 절감 및 시공관리가 용이한 층간조인트 크랙 방지 방법에 관한 것이다.The present invention relates to a method for preventing cracks in interlayer joints, and more specifically, by installing a groove on the upper surface of the interlayer joint to induce cracks, and filling the grooves with external caulking agent to cause leakage of crack putty agent In the event of subsequent deformation, only caulking agent is re-installed to minimize defect treatment for cracks.In addition, joint joint installation and surface treatment during frame construction are simplified to caulking before painting, reducing construction cost and easy construction management. It is about how to prevent cracking.
일반적으로 거의 모든 아파트에서 입주 후 수년이 경과하면서 건축물의 수축 팽창으로 인한 구조물 균열이 발생하고 균열보수 및 하자처리에 어려움을 동반하고 있다.In general, in almost all apartments, after several years have elapsed, structural cracks occur due to shrinkage and expansion of buildings, and difficulties in repairing cracks and handling defects are accompanied.
특히 아파트 층간 죠인트 부분의 경우 발생 빈도가 많고 하자보수 후에도 재차 발생하는 경우가 많다. 층간조인트는 철근콘크리트 구조물 공사에서 층간타설을 통해 발생하는 시공줄눈을 말한다. 이러한 이음부위에는 청소가 미진할 경우 균열로 형성되는 경우가 많으며 내구성 저하로 누수로 인한 하자발생의 원인이 되고 있다.In particular, joints between apartment floors are frequently occurring, and they often occur again after defect repair. Interfloor joint refers to a construction joint that occurs through interfloor casting in reinforced concrete structure construction. These joints are often formed as cracks when cleaning is insufficient, and it is a cause of defects due to leakage due to reduced durability.
일반적으로 작은 하자라고 생각하지만, 공동주택의 경우 준공 후 입주자와 법적크레임 소송의 경우 가장 많은 부분을 차지한다.In general, it is considered a small defect, but in the case of apartment houses, it occupies the most part in the case of tenants and legal claims after construction.
이는 내부마감이 있는 여러 하자와는 달리 외부환경에 그대로 노출된 균열로 인해 가시적 법적 증거자료로 활용되고 있어 더욱 논란이 되고 있다.Unlike many defects with internal finishes, this is becoming more controversial as it is used as visible legal evidence due to cracks exposed to the external environment.
