Description

일방향 볼트 체결장치One-way bolt fastener
본 발명은 일방향 볼트 체결장치에 관한 것으로, 더 상세하게는 피체결부재의 이면이 폐쇄되어 손이나 공구가 들어갈 수 없는 경우 전면 한쪽에서만 작업하여 볼트와 너트를 용이하게 체결할 수 있도록 하고, 특히 별도의 일방향 볼트 전용체결공구를 사용하지 않고 피체결부재의 전면 한쪽에서 볼트와 너트를 간단하게 체결할 수 있도록 한 일방향 볼트 체결장치에 관한 것이다.The present invention relates to a one-way bolt fastening device, and more particularly, when the back surface of the fastening member is closed so that a hand or a tool cannot be inserted, the bolt and nut can be easily fastened by only working on one side of the front surface, and in particular, The present invention relates to a one-way bolt fastening device that allows the bolt and nut to be simply fastened on the front side of the member to be fastened without using a one-way bolting fastening tool.
일반적으로 두 개의 피체결부재를 체결함에 있어서는 용접, 리벳팅, 볼트 등의 다양한 체결구조들이 적용될 수 있으나, 그 중 볼트 체결은 작업이 용이하고 열을 수반하지 아니하여 피체결부재에 대한 열변형이 발생할 우려가 없다는 점에서 가장 널리 사용되는 체결구조의 하나이다.In general, when fastening two fastened members, various fastening structures such as welding, riveting, and bolts can be applied. Among them, fastening of bolts is easy to work and does not involve heat. It is one of the most widely used fastening structures in that there is no risk of occurrence.
여기서, 볼트 체결구조는 통상적으로 피체결부재의 일면에서 체결공에 볼트를 삽입하고, 피체결부재의 타면에서 체결공을 관통하여 외부로 돌출된 볼트의 수나사에 너트의 암나사를 체결하는 구조로 이루어진다. 이때, 피체결부재의 양면은 작업자의 손이나 공구의 접근이 용이하도록 개방되어야 한다. 그러나, 종래에는 피체결부재의 이면이 폐쇄되어 손이나 공구가 들어갈 수 없는 경우, 즉 피체결부재의 양면에서 볼트와 너트를 체결할 수 없는 경우 상술한 통상적인 볼트와 너트의 체결구조로는 피체결부재를 체결할 수 없는 구조적인 문제점이 있었다.Here, the bolt fastening structure is typically made of a structure in which the bolt is inserted into the fastening hole on one surface of the fastened member, and the female screw of the nut is fastened to the male screw of the bolt projecting outward through the fastening hole on the other surface of the fastened member. . At this time, both sides of the fastening member should be opened to facilitate the access of the operator's hand or tool. However, in the related art, when the back surface of the member to be fastened is closed and a hand or a tool cannot enter, that is, when the bolt and nut cannot be fastened on both sides of the member to be fastened, the above-described conventional bolt and nut fastening structure is avoided. There was a structural problem that cannot fasten the fastening member.
이러한 문제점을 해결하기 위해 하기 특허문헌인 대한민국 특허공보 공고번호 제90-000221호에는 일방향 즉, 외면에서만 분할와셔를 개재한 보울트를 판체등의 체결공으로 집어넣어 외부조작으로 결합, 체결하는 것이 가능하고 또한 이러한 체결에 있어서도 특히 내측 분할와셔에 대한 외부에서의 조립 용이성과 그 작업안정성면에서 우수한 성가를 나타내는 분할와셔를 이용한 보울트 체결방법 및 그 장치가 기재되어 있다.In order to solve this problem, Korean Patent Publication No. 90-000221, which is the following patent document, can insert and insert a bolt having a split washer only in one direction, that is, on the outer surface, into a fastening hole such as a plate, and then connect and fasten it by external operation. Also described is a bolt fastening method and apparatus using a split washer that exhibits excellent ease of assembly from the outside with respect to the inner split washer and its work stability.
그러나 상기 선행기술은 분할와셔를 인장선으로 당겨서 하나의 와셔형태로 조합되게 하는 것으로, 분할와셔가 보이지도 않는 상태에서 인장선의 당김만으로 완전히 서로 분리된 각 분할와셔를 일체화시키면서 정위치에 자리 잡게 한다는 것은 숙련공이 아니면 현실적으로 용이하지 않을 뿐만 아니라 분할와셔의 고정작업에 많은 시간이 소요되는 문제점이 있다.However, the prior art is to pull the split washer with a tension line to be combined into a single washer form, it is to be placed in place while integrating each separate washer completely separated from each other by only pulling the tension line in the state that the split washer is not visible.
