본 발명은 너트분리방지 클램핑 볼트에 관한 것으로, 보다 상세하게는 주로 건설현장 등에서 비계 설치용으로 사용되는 비계용 클램프 등의 클램핑 볼트에 있어서, 너트가 클램핑 볼트로부터 분리되지 않도록 하는 분리방지수단을 갖춘 너트분리방지 클램핑 볼트에 관한 것이다.The present invention relates to a nut-separating clamping bolt, and more particularly, in a clamping bolt such as a scaffolding clamp mainly used for scaffolding installation in construction sites, etc., a nut having a separation preventing means for preventing the nut from being separated from the clamping bolt. The anti-separation clamping bolt.

각종 건축현장에서 비계파이프를 종횡으로 설치하는 비계용 클램프 등에는 체결쇠를 클램핑 볼트와 너트로 체결하여 조임함으로써 비계파이프를 클램핑의 몸체에 고정시키도록 구성되어 있다.In various construction sites, scaffolding clamps, which are installed horizontally and horizontally, are fastened to clamping bodies by clamping fastening bolts with clamping bolts and nuts.

이러한 비계용 클램프 등에 사용되는 클램핑 볼트는 체결된 너트를 볼트로부터 풀어낼 경우 작업의 신속성 등을 위해 전동공구 등을 사용하여 풀어내게 되는 데, 이때 상당한 주의를 기울이지 않으면 체결된 너트가 클램핑 볼트로부터 완전히 분리됨으로써 분리된 너트의 관리가 용이치 않게 되고 너트를 유실하는 경우도 빈번히 발생하는 것이었다.Clamping bolts used for such scaffolding clamps are loosened using a power tool, etc. for quickness of work when the fastened nut is released from the bolt. If the user is not careful, the fastened nut is completely removed from the clamping bolt. By separating, the management of the separated nut was not easy and the nut was frequently lost.

특히, 비계용 클램프와 같이 비계를 제거한 뒤 다음 비계설치작업을 위하여 너트를 볼트로부터 완전히 분리시키지 않고 볼트에 결합된 상태로 두었다가 차후의 비계 설치작업시에 볼트에 너트가 결합된 상태에서 곧바로 클림핑작업을 수행할 수 있도록 하는 것이 작업의 신속성과 효율성을 위해 가장 바람직한 경우, 또는 너트가 볼트에 체결된 상태에서 결합된 너트를 빈번히 조였다가 풀어내는 과정을 반복적으로 수행하는 각종의 클램프에 있어서는 너트를 조이고 푸는 작업 도중 너트가 볼트로부터 완전히 분리되면 너트를 볼트에 재결합한 뒤 체결하여야만 하고 분리된 너트는 유실 우려도 높아 작업의 효율성과 생산성이 저하될 수밖에 없는 것이 었다.In particular, after removing the scaffolding, such as the scaffolding clamp, leave the nut coupled to the bolt without completely removing it from the bolt for the next scaffold installation and immediately crimp it with the nut coupled to the bolt during subsequent scaffold installations. It is most desirable for the speed and efficiency of the work to be performed, or for various clamps that repeatedly tighten and loosen the combined nut with the nut fastened to the bolt. If the nut was completely removed from the bolt during the tightening and loosening operation, the nut must be refitted to the bolt and then tightened.

본 발명에서는 주로 비계용 클램프 등의 클램핑 볼트에 있어서 너트를 클램핑 볼트로부터 풀어낼 경우 너트가 클램핑 볼트로부터 완전히 분리되지 않고 볼트에 결합된 상태로 있게 함으로써 너트의 유실 우려를 방지함과 동시에 너트가 볼트에 결합된 상태에서 볼트에 대한 너트의 클램핑작업이 수행될 수 있도록 하고자 한다.In the present invention, mainly in clamping bolts such as scaffolding clamps, when the nut is released from the clamping bolt, the nut is not completely separated from the clamping bolt, but is coupled to the bolt to prevent the nut from being lost and at the same time the nut is The clamping of the nut against the bolt can be carried out in the coupled state.

즉, 너트를 풀고 조이는 작업은 그대로 수행되면서도 너트가 볼트로부터 분리되는 것은 방지되도록 한 것이다.In other words, while loosening and tightening the nut is performed as it is to prevent the nut from being separated from the bolt.

본 발명은 비계용 클램프 등 각종 클램프의 클램핑 볼트에 있어서, 볼트에 결합된 너트가 볼트로부터 분리되지 않도록 구성한 것에 특징이 있는바, 이하에 본 발명의 구성을 첨부 도면과 함께 구체적으로 살펴보면 다음과 같다.The present invention is characterized in that the clamping bolts of various clamps, such as scaffolding clamps, are configured such that the nut coupled to the bolt is not separated from the bolt. Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings. .

도 1은 본 발명의 하나의 실시예로서 비계용 클램프의 클램핑 볼트에 본 발명이 적용된 예를 도시한 것이며, 도 2는 본 발명의 구성도, 도 3은 본 발명의 작용상태도 이다.1 shows an example in which the present invention is applied to a clamping bolt of a scaffold clamp as an embodiment of the present invention, Figure 2 is a configuration diagram of the present invention, Figure 3 is an operational state diagram of the present invention.

비계용 클램프(10)는 공지된 바와 같이 몸체(11)와 몸체(11)에 힌지 결합되는 체결쇠(12)와, 몸체(11)에 힌지 결합된 클램핑 볼트(1)로 이루어지고, 클램핑 볼트(1)에 체결된 너트(2)가 체결쇠(12)에 조임결합되어 몸체(11)와 체결쇠(12) 사이의 비계파이프(13)를 종횡으로 고정설치하도록 구성되어 있다.Scaffolding clamp 10 is composed of a clamping bolt (12) hinged to the body 11 and the body 11, the clamping bolt (1) hinged to the body 11, as known The nut 2 fastened to (1) is fastened to the fastener 12 so that the scaffold pipe 13 between the body 11 and the fastener 12 can be fixedly installed laterally.

본 발명에서는 전술한 비계용 클램프(10) 등과 같은 각종 클램프의 클램핑 볼트(1)에 있어서, 클램핑 볼트(1)에 너트(2)의 분리방지수단을 갖춘 것이다.In the present invention, in the clamping bolt 1 of various clamps such as the above-mentioned scaffolding clamp 10, the clamping bolt 1 is provided with a separation preventing means of the nut 2.

클램핑 볼트(1)는 나사체결부(3) 일측에 끝단으로 갈수록 직경이 작은 테이퍼부(4)를 별도로 형성하고, 테이퍼부(4)에는 나사체결부(3)와 동일한 피치에서 나사산을 점차적으로 하향되게 절삭한 형태의 나사부(5)로 형성한다.The clamping bolt 1 separately forms a tapered portion 4 having a smaller diameter toward one end on one side of the screwed portion 3, and the tapered portion 4 gradually threaded at the same pitch as the screwed portion 3. It is formed by the screw part 5 of the shape cut downward.

테이퍼부(4)는 너트(2)의 폭이 충분히 수용될 수 있는 길이로 형성되어야 할 것이다.The tapered portion 4 will have to be formed in a length such that the width of the nut 2 can be sufficiently accommodated.

그리고, 나사체결부(3) 일측 테이퍼부(4)의 끝단에는 환턱(7)을 만들고 너트(2)를 나사 결합 후 이탈방지부재(6)를 환턱(7)에 끼운 다음 선단부분을 압착하여 클랭핑 볼트(1)를 구성한 것이다.Then, at the end of the tapered portion (4) of the screw fastening part 3, the round jaw (7) is made, and after the nut (2) is screwed in, the separation preventing member (6) is inserted into the round bar (7), and then the tip end is compressed. The clamping bolt 1 is configured.

이탈방지부재(6)는 클램핑 볼트(1)의 테이퍼부(4) 끝단의 환턱(7)에 너트(2)의 내경보다 큰 와셔를 삽입 후 끝단부분을 이탈방지부재(6)의 내경보다 다소 넓은 상태가 되게 압착하여 고정결합시켜 너트(2)가 클램핑 볼트(1)로부터 이탈됨으로써 분리되는 것을 방지하는 것이다. The detachment preventing member 6 inserts a washer larger than the inner diameter of the nut 2 into the round bar 7 of the end of the taper portion 4 of the clamping bolt 1, and then ends the end of the detachment member 6 with the inner diameter of the detaching preventing member 6. The nut 2 is prevented from being separated by being separated from the clamping bolt 1 by being compressed and fixed in a wide state.

상기와 같이 이탈방지부재(6)를 나사체결부(3)의 환턱(7)에 삽입 후 결합방법으로서 다른 실시 예로는 나사체결부(3)의 환턱(7)에 이탈방지부재(6)를 끼운 후 끝단부분을 다수 곳에 압점부(8) 처리하여 압접부(8) 부분이 이탈방지부재(6)의 애경보다 다소 돌출되게 하여 일체화한다.Insertion of the separation preventing member 6 into the annulus 7 of the screw fastening portion 3 as described above as another method of coupling the separation preventing member 6 to the annulus (7) of the screw fastening portion (3) After inserting, the end portion is treated with a pressure point 8 in a number of places so that the part of the pressure contact portion 8 protrudes somewhat more than the diameter of the separation preventing member 6 to be integrated.

이러한 이탈방지부재(6)는 위에서 전술한 예 외에도 등가의 여러 수단으로 실시할 수 있을 것이다.The separation preventing member 6 may be implemented by various equivalent means in addition to the above-described examples.

이상과 같이 구성된 본 발명은 클램핑 볼트(1)에 너트(2)가 결합된 상태에서 클램핑 작업 등이 이루어져 너트(2)가 클램핑 볼트(1)로부터 분리되어 유실되거나 클램핑 볼트(1)로부터 분리된 너트(2)를 재결합하여 체결작업할 필요없이 너트(2)가 클램핑 볼트(1)에 결합된 상태에서 곧바로 체결작업이 이루어지는 것으로, 이하에 본 발명의 특징적인 작용에 대하여 살펴보면 다음과 같다.According to the present invention configured as described above, the clamping operation is performed while the nut 2 is coupled to the clamping bolt 1, and the nut 2 is separated from the clamping bolt 1 and is lost or separated from the clamping bolt 1. The fastening operation is performed immediately in the state in which the nut 2 is coupled to the clamping bolt 1 without the need for rejoining the nut 2, and the characteristic operation of the present invention will be described below.

본 발명에 의한 클램핑 볼트(1)는 도 3과 같이 나사체결부(3)로부터 너트(2)를 풀어내게 되면 나사체결부(3) 일단에 형성된 테이퍼부(4)의 나사부(5)로 너트(2)가 풀려지면서 이동하게 된다.When the clamping bolt 1 according to the present invention is to unscrew the nut 2 from the screw fastening portion 3 as shown in Figure 3 nut to the threaded portion 5 of the tapered portion 4 formed on one end of the screw fastening portion 3 (2) is released and moves.

테이퍼부(4)의 나사부(5)로 이동된 너트(2)는 너트(2)의 내경보다 작은 테이퍼부(4)에 위치하게 되므로 클램핑 볼트(1)의 나사체결부(3)에 대한 나사 결합력을 상실하게 된다.The nut 2 moved to the threaded portion 5 of the tapered portion 4 is located in the tapered portion 4 smaller than the inner diameter of the nut 2, so that the screw to the screwed portion 3 of the clamping bolt 1 The bond will be lost.

이와 같이 테이퍼부(4)에 이동된 너트(2)는 끝단의 이탈방지부재(6)에 의하여 클램핑 볼트(1)로부터 이탈되지 않고 테이퍼부(4)에 머물러 있는 단순 결합상태를 유지하게 된다.In this way, the nut 2 moved to the tapered portion 4 maintains a simple engagement state in which the nut 2 is not detached from the clamping bolt 1 by the release preventing member 6 at the end and stays in the tapered portion 4.

그리고 너트(2)를 나사체결부(3)에 나사체결하는 작업을 수행함에 있어서는 테이퍼부(4)에 있는 너트(2)를 돌려서 나사체결부(3)로 체결작업을 진행하게 되면 테이퍼부(4)에 형성된 나사부(5)의 안내에 따라 너트(2)가 점진적이면서 자연스럽게 나사체결부(3)에 나사결합되어 체결작업이 이루어지므로 너트(2)의 체결작업을 보다 기민하고 용이하게 수행할 수 있게 된다.In the case of screwing the nut 2 to the screwing part 3, when the nut 2 of the taper part 4 is turned to proceed to the screwing part 3, the taper part ( 4) The nut 2 is gradually and naturally screwed to the screwing part 3 according to the guide of the threaded part 5 formed therein, so that the tightening work is more agile and easier to perform. It becomes possible.

따라서, 도 1의 비계용 클램프(10) 등에서와 같이 너트(2)가 클램핑 볼트(1)로부터 분리되지 않은 상태에서 비계파이프(13)의 클램핑작업을 위한 너트(2)의 풀고 조이는 작업이 이루어져 안정되고 기민한 클램핑 작업을 수행할 수 있게 된다.Accordingly, as shown in the scaffold clamp 10 of FIG. 1, the unwinding and tightening operation of the nut 2 for clamping the scaffold pipe 13 is performed while the nut 2 is not separated from the clamping bolt 1. Stable and agile clamping can be performed.

이상에서 본 발명은 비계용 클램프(10)의 클램핑 볼트(1)를 일례로 중점 설명하고 있으나, 너트(2)의 분리방지기능을 갖춘 본 발명은 언급된 비계용 클램프(10) 뿐만 아니라 클램핑 볼트(1)로부터 너트(2)를 완전히 분리시키지 않은 상태에서 반복적이고 빈번하게 너트(2)를 조이고 푸는 클램핑작업이 요구되는 여러 클램프의 클램핑 볼트(1)에 적용된다. Although the present invention focuses on the clamping bolt 1 of the scaffold clamp 10 as an example, the present invention with a separation prevention function of the nut 2 is not only the clamping bolt 10 but also the clamping bolt mentioned. It is applied to clamping bolts 1 of several clamps, which require clamping operations to repeatedly and frequently tighten and loosen the nut 2 repeatedly without completely removing the nut 2 from (1).

이상에서 살펴본 바와 같이 본 발명은 비계용 클램프(10) 등에 있어서, 클램핑 볼트(1)에 결합된 너트(2)를 풀고 조이는 작업은 그대로 수행하면서도 너트(2)가 클램핑 볼트(1)로부터 분리되지 않은 상태에서 클램핑 볼트(1)와 너트(2)간의 체결작업이 이루어져 클램핑 작업의 신속성과 효율성을 배가시킬 수 있는 등의 이점과 효과를 기대할 수 있다.As described above, in the present invention, in the clamp 10 for the scaffold, the nut 2 is not separated from the clamping bolt 1 while the nuts 2 coupled to the clamping bolt 1 are loosened and tightened. In this case, the clamping bolt 1 and the nut 2 are fastened, and thus the advantages and effects of the fastening and the efficiency of the clamping work can be doubled.
