Description
본 고안은 볼트체결장치에 관한 것으로서, 특히 볼트부재와 볼팅 대상면이 이루는 각도에 따라 대응될 수 있도록 그 구조가 개선된 볼트체결장치에 관한 것이다.The present invention relates to a bolt fastening device, and more particularly to a bolt fastening device having an improved structure so that the bolt member and the bolting target surface can correspond to the angle.
도 1을 참조하여, 일반적인 볼팅작업은 볼팅 대상면(1)의 외측으로 돌출된 볼트부재(2)의 단부에 너트부재(10)를 체결하고 상기 볼팅 대상면(1)에 너트부재(10)가 밀착되도록 조여주는 것이다. 그러나, 도시된 바와 같이 볼팅 대상면(1)의 외측으로 돌출된 볼트부재(2)가 볼팅 대상면(1)과 수직을 이루지 못하고 일측으로 기울어진 경우, 너트부재(10)는 볼팅 대상면(1)과 선 접촉되며 정확한 볼팅작업이 이루어지지 못한다. 더욱이, 그 이상 무리한 힘으로 볼트부재(10)를 조이면 볼트부재(10) 및 너트부재(2)의 나사산이 일그러져 더욱 좋지 않다.Referring to Figure 1, the general bolting operation is to fasten the nut member 10 to the end of the bolt member (2) protruding out of the bolting target surface (1) and the nut member (10) on the bolting target surface (1) Tighten so that the close contact. However, as shown, when the bolt member 2 protruding outward from the bolting target surface 1 is not perpendicular to the bolting target surface 1 and is inclined to one side, the nut member 10 is the bolting target surface ( It is in line with 1) and the exact bolting work cannot be done. Furthermore, if the bolt member 10 is tightened with excessive force, the threads of the bolt member 10 and the nut member 2 are distorted, which is not good.
특히, 프리스트레싱(Prestressing)을 이용한 구조물 또는 포스트텐셔닝(Post-Tensioning) 구조물에 응력도입을 위한 강선등에 적용되는 볼트체결장치의 경우, 고도로 정확한 볼팅작업을 요하며 볼팅작업후에도 볼팅된 부분에 지속적으로 강한 장력이 작용되므로, 상기한 문제로 인하여 부정확한 볼팅작업이 이루어졌다면 볼팅부의 내구성이 떨어지게 된다.In particular, bolt fastening devices that are applied to steel wires for stress introduction to structures using prestressing or post-tensioning structures require highly accurate bolting operations and continue to be bolted after the bolting operation. Since a strong tension is applied, if the incorrect bolting operation is made due to the above problem, the durability of the bolting portion is reduced.
상기와 같이 볼팅 대상면과 볼트부재가 수직을 이루지 못하고 일측으로 기운 경우, 볼팅 대상면 상에 상기 볼트부재에 체결되는 너트부재가 면 접촉된 상태로 조여질 수 있도록 별도의 브라켓(도시하지 않음) 등을 설치하여 보완하기도 하지만, 응력이 일정치 않아 변이가 발생되며 볼팅작업 공수가 늘어나 번거롭고 비교적 작은 볼팅 대상면에 대한 볼팅작업에는 적용이 쉽지 않은 문제점들이 여전히 남아있다.As described above, when the bolting target surface and the bolt member are tilted to one side without being vertical, a separate bracket (not shown) may be tightened while the nut member fastened to the bolt member on the bolting target surface is in surface contact. Although it is supplemented by installing the back, there is still a problem that is not easy to apply to the bolting work on the cumbersome and relatively small bolting target surface due to the variation in stress is not constant, the number of bolting work is increased.
본 고안은 이와 같은 문제점들을 고려하여 안출된 것으로서, 볼팅 대상면 외측으로 돌출된 볼트부재가 볼팅 대상면과 수직을 이루지 못하고 기운 상태와 같이 볼트부재와 볼팅대상면이 이루는 각도에 관련한 변화에 대응하여 정확한 볼팅작업이 가능한 볼트체결장치를 제공하는 것을 과제로 한다.The present invention has been devised in view of the above problems, and the bolt member protruding outside the bolting target surface is not perpendicular to the bolting target surface and responds to the change related to the angle between the bolt member and the bolting target surface as inclined. An object of the present invention is to provide a bolting device capable of accurate bolting work.

상기 과제를 해결하기 위하여 본 고안은, 볼트부재에 체결하기 위한 너트부재와, 상기 볼트부재가 관통되어 진입된 각도변화에 대응될 수 있게 뚫어 놓은 볼트관통구멍과 이의 일측에 구형으로 오목하게 형성한 베어링요홈부를 가지는 너트받이와, 상기 너트부재와 너트받이 사이에 개재되어 상기 볼트부재를 관통시키게 뚫어놓은 구멍과 이의 일측에 상기 너트부재가 안착되는 안착면 및 그 타측에 구형으로 볼록하게 형성하여 상기 너트받이의 베어링요홈부와 면 접촉하게 된 베어링돌출부를 가지는 베어링부재가 구비된 볼트체결장치를 구성하였다.In order to solve the above problems, the present invention, a nut member for fastening to the bolt member, and formed through the bolt through hole drilled so as to correspond to the angle change entered through the bolt member and a spherical concave in one side thereof. A nut receiving part having a bearing recess, a hole interposed between the nut member and the nut receiving part, and a hole formed to penetrate the bolt member, and a seating surface on which the nut member is seated on one side thereof, and a convex shape on the other side thereof. A bolt fastening device with a bearing member having a bearing protrusion brought into surface contact with a bearing recess of a nut receiver was constructed.
상기한 볼트부재는 일반적인 체결고정수단으로서의 나사산이 형성된 볼트뿐만이 아니라, 프리스트레싱 및 포스트텐셔닝공법을 이용한 구조물에 응력도입을 위한 강재(Tendon) 예를 들어, PC(Prestressed Concrete) 강선, PC 강봉 및 PC 강꼬임선 등을 배제하지 않는다.The bolt member is not only a threaded bolt as a general fastening means, but also a steel (Tendon), for example, PC (Prestressed Concrete) wire, PC steel rod and PC for stress introduction to a structure using prestressing and posttensioning techniques. Do not rule out twisted pairs.
상기 너트부재 역시 일반 볼트체결용 너트 외에 클램프방식이나 플랜지형 고정환 등을 배제하지 않는 것이다.The nut member also does not exclude a clamping method or a flanged fixed ring in addition to the general bolt fastening nut.
이에 따라 본 고안에 따른 볼트체결장치는, 볼팅 대상면 외측으로 돌출된 볼트부재가 볼팅 대상면과 수직이 아닌 상태에서 너트부재가 체결되더라도, 이 너트부재가 상기 베어링부재의 안착면에 면 접촉된 상태로 조여지도록 상기 너트받이의 베어링요홈부에서 베어링부재가 유동됨으로써, 정확한 볼팅작업이 가능하게 된다.Accordingly, in the bolt fastening device according to the present invention, even if the bolt member protruding outside the bolting target surface is not perpendicular to the bolting target surface, the nut member is in surface contact with the seating surface of the bearing member. As the bearing member flows in the bearing recess of the nut receiver to be tightened in a state, accurate bolting operation is possible.
이와 같은 본 고안에 따른 볼트체결장치를 첨부된 도면을 참조하면서 그 바람직한 실시예를 설명하면 다음과 같다.Referring to the attached bolt fastening device according to the present invention as described above the preferred embodiment as follows.
첨부된 도면중 도 2 내지 도 5는 본 고안에 따른 볼트체결장치의 실시예들로서 체결상태의 측단면도를 보이고 있다.2 to 5 of the accompanying drawings shows a side cross-sectional view of the fastening state as embodiments of the bolting device according to the present invention.
도 2는 본 고안에 따른 볼트체결장치의 일 실시예로서 기본적인 구성의 체결상태의 측단면도이다. 볼팅작업 순서를 따라 설명하면, 볼팅 대상면(1) 외측으로 돌출된 볼트부재(2)에, 먼저 너트받이(20)의 볼트관통구멍(21)을 통과시켜 볼팅 대상면(1) 상에 위치시키고, 다시 베어링부재(30)의 구멍(31)을 통과시켜 이 베어링부재(30)의 베어링돌출부(33)와 상기 너트받이(20)의 베어링요홈부(22)가 면 접촉되게 위치시킨 후, 마지막으로 너트부재(10)를 체결하여 조여줌으로써 볼팅작업이 완료된다.Figure 2 is a side cross-sectional view of a fastening state of the basic configuration as an embodiment of the bolting device according to the present invention. In the order of the bolting operation, the bolt member 2 protruding outward from the bolting target surface 1 first passes through the bolt through hole 21 of the nut receiver 20 and is positioned on the bolting target surface 1. After passing through the hole 31 of the bearing member 30 again, the bearing protrusion 33 of the bearing member 30 and the bearing recess 22 of the nut receiver 20 are placed in surface contact with each other. Finally, the bolting work is completed by tightening and tightening the nut member 10.
이때, 도면에 나타낸 것처럼 볼팅 대상면(1)과 볼트부재(2)가 수직이 아닌 경우, 너트부재(10)를 조임에 따라서 베어링돌출부(33)와 베어링요홈부(22)의 접촉면 사이에 유동이 발생하므로, 언제나 너트부재(10)가 베어링부재(30)의 안착면(32)에 면 접촉된 상태로 조여지게 된다. 즉, 종래예에서 전술한 바와 같이 너트부재가 볼팅 대상면과 선 접촉되어 발생되는 불완전한 볼팅작업이 이루어지는 문제나, 그 이상 과도한 힘으로 너트부재를 조임에 따라 볼트부재 및 너트부재의 나사산이 일그러지게 되는 문제가 해결된 것이다.At this time, when the bolting target surface 1 and the bolt member 2 are not vertical, as shown in the drawing, flows between the contact surface of the bearing protrusion 33 and the bearing recess 22 as the nut member 10 is tightened. As such, the nut member 10 is always tightened in surface contact with the seating surface 32 of the bearing member 30. That is, as described above in the prior art, the nut member is in contact with the bolting target surface, and an incomplete bolting operation occurs, or the screw member of the bolt member and the nut member are distorted as the nut member is tightened with excessive force. The problem is solved.
그리고 도면에 나타난 바와 같이, 너트받이(20)에 형성된 볼트관통구멍(21)의 크기에 따라 볼팅 대상면(1)과 볼트부재(2)가 이루는 각도에 대하여 θ만큼의 적용범위를 갖게된다.And, as shown in the drawing, according to the size of the bolt through hole 21 formed in the nut receiving 20 has an application range of θ for the angle formed by the bolting target surface 1 and the bolt member (2).
또한 도 3의 실시예에 나타낸 바와 같이, 상기 볼트부재(2)를 관통시키게 뚫어 놓은 구멍(41)과 이의 일측에 구형으로 오목하게 형성하여 베어링부재(30)의 베어링돌출부(33)와 면 접촉하게 된 보조베어링요홈부(42) 및 그 타측에 구형으로 볼록하게 형성하여 너트받이(20)의 베어링요홈부(22)와 면 접촉하게 된 보조베어링돌출부(43)를 가지는 보조베어링부재(40)를 베어링부재(30)와 너트받이(20) 사이에 개재시킬 수도 있다.In addition, as shown in the embodiment of Fig. 3, the hole 41 is formed through the bolt member 2 to penetrate and formed in a concave shape on one side thereof so as to make a surface contact with the bearing protrusion 33 of the bearing member 30 Auxiliary bearing member (40) having the auxiliary bearing groove portion 42 and the auxiliary bearing protrusion (43) which is formed in a convex shape on the other side thereof and is in contact with the bearing groove portion 22 of the nut receiving 20. It may be interposed between the bearing member 30 and the nut receiving 20.
본 실시예에 의하면, 본 고안의 제작편의를 위해 볼트부재(2)의 규격에 따라 베어링부재(30)를 규격화하더라도 상기 보조베어링부재(40)가 어댑터의 역할을 하여 다양한 작업조건에 적용될 수 있다. 예를들어, 본 실시예에 도시된 바와 같이 볼트관통구멍(21)의 사이즈가 크고 두꺼운 너트받이(20)와 보조베어링부재(40)를 사용함에 따라 θ'로 확대된 적용범위를 갖게 됨을 알 수 있다.According to this embodiment, the auxiliary bearing member 40 acts as an adapter and can be applied to various working conditions even if the bearing member 30 is standardized according to the specification of the bolt member 2 for the convenience of manufacture of the present invention. . For example, as shown in the present embodiment, it is understood that the bolt through-hole 21 has a large size and a wider range of application to θ 'as the thick nut holder 20 and the auxiliary bearing member 40 are used. Can be.
도 4는 도 2의 실시예에 베어링요홈부(52)를 양측에 갖는 너트받이(50)가 채용된 실시예의 측단면도로서, 너트받이(50)의 방향성을 없애고 볼팅 대상면(1)과 맞닿는 부분의 면적을 줄인 실시예이다.FIG. 4 is a side cross-sectional view of an embodiment in which the nut receiver 50 having the bearing recesses 52 on both sides is adopted in the embodiment of FIG. 2, and the nut receiver 50 is contacted with the bolting target surface 1. An embodiment in which the area of the portion is reduced.
도 5는 도 3의 실시예에 베어링요홈부(52)를 양측에 갖는 너트받이(50)가 채용된 실시예의 측단면도를 나타낸 것이다.5 is a side cross-sectional view of an embodiment in which the nut receiving 50 having the bearing recess 52 on both sides is employed in the embodiment of FIG. 3.
이상과 같이 살펴본 상기 실시예들은 본 고안에 따른 바람직한 몇몇의 실시예를 설명한 것에 불과하고, 본 고안의 적용 범위는 이것에만 한정되는 것이 아니며, 동일 사상의 범주내에서 적절하게 변경 가능한 것이다. 예를 들어, 상기 베어링부재가 상기 볼트부재를 체결하기 위한 너트부재에 일체로 형성하면 볼팅작업시 작업편의를 향상시킬 수 있는 것이다.The embodiments described above are merely to describe some preferred embodiments according to the present invention, the scope of application of the present invention is not limited to this, it can be changed appropriately within the scope of the same idea. For example, when the bearing member is integrally formed with the nut member for fastening the bolt member, the work piece can be improved during the bolting operation.
본 고안 볼트체결장치에 의하면, 볼팅 대상면 외측으로 돌출된 볼트부재가 볼팅 대상면과 수직이 아닌 상태에서 너트부재가 체결되더라도, 이 너트부재가 상기 베어링부재 일측의 안착면에 면 접촉된 상태로 조여지도록, 너트받이의 베어링요홈부에서 베어링부재 타측의 베어링돌출부가 유동되기 때문에, 언제나 정확한 볼팅작업이 가능하게 되고, 응력이 일정하여 변이발생이 없으며, 볼팅된 부분의 내구성이 향상되는 효과가 있다.According to the bolt fastening device of the present invention, even if the nut member is fastened in a state where the bolt member protruding outside the bolting target surface is not perpendicular to the bolting target surface, the nut member is in surface contact with the seating surface of one side of the bearing member. To be tightened, since the bearing protrusion of the bearing member on the other side flows from the bearing recess of the nut receiver, accurate bolting is always possible, and there is no variation due to the constant stress, and the durability of the bolted part is improved. .
또한, 종래와 같이 볼팅 대상면 외측으로 돌출된 볼트부재가 볼팅 대상면과 수직을 이루고 있지 못한 경우, 별도의 브라켓 등을 설치할 필요 없이 볼트부재를 조여주는 것만으로 작업이 완료되므로 간편하고 손쉬운 볼팅작업이 이루어진다.In addition, when the bolt member protruding outside the bolting target surface is not perpendicular to the bolting target surface as in the prior art, the bolting member is completed by simply tightening the bolt member without installing a separate bracket. This is done.
그리고, 보조베어링부재 및 너트부재의 선택에 따라 다양한 볼팅작업조건에 맞게 적용될 수 있는 장점이 있다.In addition, according to the selection of the auxiliary bearing member and the nut member there is an advantage that can be applied to various bolting working conditions.
