Abstract: 콘크리트 구조물에 균열이 발생하게 되면, 균열이 더 이상 진행되는 것을 막을 수 있도록 균열부위에 주입기구를 설치하고 주입기를 연결하여 보수액을 주입하게 된다. 이때 사용되는 대표적인 주입기구가 패커 이다.  
종래의 패커는 고정용 고무 슬리브가 헛도는 경우가 많아 천공한 주입구를 사용하지 못하게 된다. 또한 균열 내부에 보수액을 주입하는 중에 설치된 패커가 빠져나오게 되어 작업자의 안전을 위협하게 되고 시공 불량으로 이어진다.  
또한 금속에 포함된 철 성분에 의해 녹이 발생하여 마감 후 구조물의 표면을 오염시키는 경우가 있으며, 플라스틱 재질 등에 비해 경제적이지 못하고, 재작업을 해야 하는 경우 기존의 주입구를 사용하지 못한다. 
본 발명의 패커는 설치시 외 측에 , 외 측에 주입구보다 약간 크게 형성된 래칫 모양의 톱니가 형성된 래칫형 너트(6)가 주입구 홀 면에 밀착되어 헛도는 것을 방지하게 된다.     
또한 고무 슬리브(55)와 함께 원통에 여러 가닥의 홈이 형성된 콜릿형 슬리브(44)도 함께 축 방향으로 수축되어 원주가 팽창하여 주입구에 견고하게 밀착되어, 주입압력에 의한 패커의 빠짐을 방지한다.  
 또한 모든 구성을 플라스틱으로 제작하는 것이 가능하다. 따라서 플라스틱으로 제작할 경우 녹이 발생하지 않아 마감 후 구조물의 표면을 오염시키지 않고, 재 작업시 기존의 주입구를 재천공하여 플라스틱 잔유물을 제거하고 주입구를 재사용할 수 있다. 
따라서 본 발명의 패커는 종래에 비하여 경제적이며 작업품질향상의 효과를 갖는다.

Abstract: 정부에서는 대형 지하실 흙막이 공사에 계측관리를 의무화 하였으며 터널이나 교량등 공공구조물에서도 상시계측을 하고 있다. 그러나 대부분 외국에서 도입한 각종 값비싼 계측기를 부적합한 위치에 부적합한 방법으로 부착 관리하고 있어서 안전진단 효과가 미미한 실정에 있다. 교량, 터널, 댐 등 토목구조물은 도 3과 같이 지점의 이동 또는 구조물의 회전, 전도 여부를 측정하는 것이 주된 계측이라고 할 수 있으나 이를 건축구조물과 지하실 흙막이 공사에 적용하기에는 부적합하다. 
     댐이나 교량의 피어는 도 3과 같이 강성이 커서 그 자체의 휨변형이 미미하므로 하나의 경사계를 어느 위치에 부착해도 회전 여부를 측정하기에 충분하다. 그러나 건축구조물 기둥은 도 4와 같이 대부분 강성이 약하여 변형곡선이 직선과는 멀기 때문에 아래층과 윗층 사이 기둥의 어느 부위에 경사계를 부착해도 층간변위를 대표하는 자료가 될 수 없다. 도 5에서도 트러스에 휨변형곡선을 따라 여러 개의 경사계를 연이어서 부착한다고 해도 중앙 최대처짐량을 계산하는 것이 어렵다. 그러나 만약 도 4의 1층, 2층 사이를 직선으로 연결하고, 도 5의 트러스 고정단과 중앙점을 직선(강선)으로 연결하여 직선이 두 점 사이에서 기울어지는 각도를 측정하면, 기둥과 트러스가 휨변형으로 야기되는 층간변위 및 중앙 최대처짐량은 3각법으로 쉽게 계산할 수 있다. 또한 강선의 길이가 길어서 자중으로 구부러지는 곡률은 두 지점 간에 변위가 생긴다고 해도 곡률에는 영향을 주지 않으므로 상기 각도 에는 차이가 없게 된다.

Abstract: 본 발명은 스트립 속도 측정 장치에 관한 것으로서, 사상압연기의 출구측에 위치하고 사상압연기에서 송출되는 스트립의 이송경로 하측에 배치되어 스트립의 이송 시 발생되는 유도전류에 의해 스트립의 속도를 측정하는 속도측정부와, 사상압연기의 출구측에 위치하고 속도측정부의 전측에 배치되며 스트립의 상부 표면의 이물질을 제거하도록 스트립의 상부를 향해 유체를 분사하는 상분사부와, 사상압연기의 출구측에 위치하고 속도측정부의 전측에 배치되며 스트립의 하부 표면의 이물질을 제거하도록 스트립의 하부를 향해 유체를 분사하는 하분사부를 포함하는 것을 특징으로 한다.  
본 발명에 따르면, 사상압연기에서 송출되는 스트립의 속도를 유도전류를 이용하여 실시간으로 정확하게 측정할 수 있다.
