Description
본 발명은 토목, 건축에 이용되는 재인장형 앵커의 헤드와 재인장 장치에 관한 것으로서, 특히 재인장이 극히 용이하도록된 앵커의 헤드와 재인장 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head and a retensioning device of a re-tensioning anchor used in civil engineering and construction, and more particularly, to a head and a re-tensioning device of an anchor which is extremely easy to retension.
종래의 토목, 건축에 이용되는 재인장형 앵커의 헤드는 재인장을 위하여 헤드의 상부로 재인장용 강선이 여유있게 돌출되어 있어야 하므로 이로인한 작업에 불편이 있는 결점이 있으며 도4에서 참조되는 바와같이, 또한 볼트와 너트방식을 이용하므로 여유 강선(STRAND)를 이용하여 재인장후 앵커의 헤드 둘레에 볼트형 나사산(100)을 형성하고 상기 나사산과 너트형 나사산(200)을 형성한 너트(400)를 강선(300)을 인장한 다음 인장된 높이만큼 너트(400)를 하향시킨 후 작업을 하게되어 있는 것이 있으나 이 경우에는 강선을 충분히 잡아당길 수 있도록 하기위하여 강선(300)을 헤드위로 높이를 높게 돌출되게 해야하고 또한 헤드의 둘레와 너트에는 나사산을 형성하였으므로 사용도중 나사산이 망가져서 파지력이 약해지는 결점이 있게 된다.The head of the re-tensioning anchor used in conventional civil engineering and construction has a drawback that is inconvenient in the work because the re-stretching wire should be protruded to the upper part of the head for re-tensioning, as shown in Figure 4, In addition, since the bolt and nut method is used, the bolt 400 is formed around the head of the anchor after re-tensioning using a spare steel wire, and the nut 400 having the thread and the nut 200 is formed. After pulling the 300, the nut 400 is lowered by the stretched height, but in this case, the steel wire 300 is projected high above the head so as to sufficiently pull the steel wire. In addition, since the thread is formed in the circumference of the head and the nut, there is a drawback that the thread is broken during use and the gripping force is weakened.
본 발명은 상기한 바와같은 종래의 토목, 건축에 이용되는 재인장형 앵커의 결점을 개량하여 재인장이 극히 용이하고 재인장시 앵커의 헤드가 훼손될 염려가없이 재인장을 할 수 있고 재인장용 강선을 해드 상부로 높게 노출시킬 필요가 없으므로 작업이 쉽고 상부로 높게 노출된 재인장용 여유 강선(STRAND)를 커버하기위해서 주변을 콘크리트로 높혀야하는 작업을 해야하는 불편이 없게한 토목, 건축용 재인장형 앵커의 헤드와 재인장 장치를 제공코저 하는 것으로서 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention improves the shortcomings of the re-tension anchor used in conventional civil engineering and construction as described above, re-tensioning is extremely easy and can be re-tensioned without fear of damage to the anchor head when re-tensioning and the re-strengthened steel wire It is easy to work because it does not need to be exposed high to the top, and the head of civil engineering and building re-tensioning anchor which has no inconvenience of having to raise the surroundings with concrete in order to cover the re-stretching steel wire exposed to the top. When providing a re-tensioning device as described in detail with reference to the accompanying drawings as follows.
