More specifically, a cone is formed by welding conical cones with a left-handed thread to both ends of a steel pipe to make members. The inner sleeve of the nut and the outer threaded sleeve nut are inserted in sequence, and the sleeve is fixed with a pin. Then, the inner screw of the cone and the outer screw of the sleeve nut are screwed together to make holes in the body surface of the member. The bolt structure can be easily assembled without the need for a non-corrosive member such as hot-dip galvanized, and the space frame connection structure to obtain a member.

Due to this, there are disadvantages such as cross-sectional defects of the member 110 pipe, resulting in a decrease in strength and aesthetic appearance.
따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서 본 고안의 주된 목적으로는 안쪽으로 좌나사가 가공되어 있는 원추형의 콘을 강관의 양끝에 용접하여 멤버를 만들고, 그 멤버의 콘 내부에 결합되는 볼트에 바깥쪽에 나사가 가공된 슬리브너트 및 슬리브를 순차적으로 끼워 넣어 핀으로 슬리브를 고정한 다음 콘의 안쪽나사와 슬리브너트의 바깥쪽 나사를 나사 조립하고, 볼트를 연결볼의 외면에 여러 개가 형성된 나사공에 나사결합하여 멤버세트와 연결볼을 조립토록함으로서, 멤버의 몸체 표면에 구멍을 뚫지 않고서도 볼트를 쉽게 조립할 수 있음은 물론, 표면이 용융아연도금과 같은 부식방지처리가 된 멤버를 얻을 수 있도록 한 스페이스 프레임의 연결구조를 제공하는 데 있다. Therefore, the present invention was devised to solve the conventional problems as described above, and the main purpose of the present invention is to make a member by welding conical cones with left-handed screws to both ends of steel pipes, Fix the sleeve with a pin by inserting the sleeve nut with the screw on the outside and the sleeve in sequence to the bolt that is connected to the inside of the cone, and then screw-assemble the inner screw of the cone and the outer screw of the sleeve nut, By assembling the member set and the connecting ball by screwing into several threaded holes on the member, the bolt can be easily assembled without having to make a hole in the body surface of the member, and the surface is protected from corrosion such as hot dip galvanizing.

이하, 첨부한 도면에 의거하여 본 고안의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 스페이스 프레임의 연결구조를 보인 횡단면도이다.Figure 2 is a cross-sectional view showing a connection structure of the space frame according to the present invention.
본 고안에 따른 스페이스 프레임의 연결구조는 도 2에 도시한 바와 같이, 외주면에 여러 개의 나사구멍(61)이 형성된 연결볼(60)에 멤버(10)를 결합하기 위해서는 먼저, 안쪽에 좌나사(12')가 형성된 원추형의 콘(12)을 멤버(10)의 양 끝단에 용접설치한다. Space structure connection structure according to the present invention, as shown in Figure 2, in order to couple the member 10 to the connection ball 60 formed with a plurality of screw holes 61 on the outer peripheral surface, first, the left screw ( The conical cone 12 having the 12 'formed therein is welded to both ends of the member 10.
이어, 외주면에 나사부가 형성된 슬리브너트(40) 및 내주면에 관통형성되는 장공(31)에 핀(50)이 결합되는 슬리브(30)를 볼트(20)에 순차적으로 결합한다.Subsequently, the sleeve nut 40 having the threaded portion formed on the outer circumferential surface and the sleeve 30 having the pin 50 coupled to the long hole 31 formed through the inner circumferential surface are sequentially coupled to the bolt 20.
이때, 볼트(20)에 형성되는 핀구멍(23)과 슬리브(30)에 관통형성되는 장공(31)을 서로 일치시킨 다음, 장공(31)과 핀구멍(23)에 핀(50)을 끼움결하여 볼트(20), 슬리브너트(40), 슬리브(30)가 일체로 결합되도록 한다.At this time, the pin hole 23 formed in the bolt 20 and the long hole 31 formed through the sleeve 30 coincide with each other, and then the pin 50 is fitted into the long hole 31 and the pin hole 23. As a result, the bolt 20, the sleeve nut 40, and the sleeve 30 are integrally coupled.
또한, 슬리브(30)는 내경 단면이 원형이며, 외부 단면은 랜치 등의 도구로 돌릴 수 있도록 다각형의 단면구조를 갖도록 한다.In addition, the sleeve 30 has a circular internal cross section, and the external cross section has a polygonal cross-sectional structure so as to be turned by a tool such as a wrench.
이어, 볼트(20)의 머리부분을 멤버(10)에 삽입 후, 슬리브너트(40)를 회전시키게 되면, 콘(12)의 안쪽에 형성된 좌나사(12')와 슬리브너트(40)의 외면에 형성된 나사부(40')에 의해 서로 나사결합되면서 멤버(10)를 구성하게 된다.Subsequently, when the head of the bolt 20 is inserted into the member 10 and the sleeve nut 40 is rotated, the outer surface of the left screw 12 'and the sleeve nut 40 formed on the inside of the cone 12 are rotated. The member 10 is configured by being screwed together by the threaded portion 40 '.
이어, 멤버(10)의 단부에 노출되는 볼트(20)의 나사부(22)를 연결볼(60)의 나사구멍(61)에 맞춰 끼운 다음, 슬리브(30)를 회전시키게 되면 상기 슬리브(30)와 함께 볼트(20)도 같이 회전하게 됨으로서 멤버(10)와 연결볼(60)이 견고하게 결합되게 된다. Subsequently, the threaded portion 22 of the bolt 20 exposed at the end of the member 10 is fitted to the screw hole 61 of the connecting ball 60, and then the sleeve 30 is rotated. The bolt 20 is also rotated together with the member 10 and the connection ball 60 is firmly coupled.
이때, 볼트(20)와 연결볼(60)의 나사구멍(61)에 가공된 나사는 우나사이고, 슬리브너트(40)와 콘(12)에 가공된 나사는 좌나사이므로 슬리브(30)를 회전시켜 볼트(20)에 강력한 회전력을 주어 볼트(20)를 연결볼(60)의 나사구멍(61)에 튼튼히 연결할 때, 이보다 먼저 콘(12)의 나사부(12')에 조여있는 슬리브너트(40)가 볼트(20)와 같이 따라 회전할 경우라도 더욱 더 조여지면서 느슨히 풀리는 것을 방지할 수 있게 된다.At this time, the screw machined in the screw hole 61 of the bolt 20 and the connecting ball 60 is the right hand thread, and the screw machined in the sleeve nut 40 and the cone 12 is the left hand screw to rotate the sleeve 30. When the bolt 20 is firmly connected to the screw hole 61 of the connecting ball 60 by giving a strong rotational force to the bolt 20, the sleeve nut 40 tightened to the threaded portion 12 'of the cone 12 before the bolt 20 is tightened. ), Even when rotated along with the bolt 20 can be further tightened to prevent loose loosening.
이와 같은 방법으로 연결볼(60)에 여러 개의 멤버(10)를 결합하고, 이러한 연결볼(60)과 멤버(10)의 결합체를 다수 개 연결하여 원하는 형태로 만들어줌으로써 스페이스 프레임의 연결구조를 완성할 수 있다. Combine several members 10 to the connection ball 60 in this way, and complete the connection structure of the space frame by connecting a plurality of the combination of the connection ball 60 and the member 10 to the desired shape can do.
또한, 이와 같은 연결구조에 의하면, 멤버(10)의 내외부 표면에 부식방지처리를 시행하기 위해서 멤버(10)를 용융아연도금조에 담금으로써 방식처리를 하고, 멤버(10) 양끝의 콘(12)의 나사에 묻은 아연을 제거한 후 볼트, 슬리브너트, 슬리브로 이루어진 슬리브세트를 조립함으로서, 멤버에 볼트를 조립하기 위한 구멍을 뚫지 않고서도 완전한 방식처리가 된 멤버세트를 제작할 수 있다.In addition, according to such a connection structure, in order to perform anti-corrosion treatment on the inner and outer surfaces of the member 10, anticorrosive treatment is performed by immersing the member 10 in a hot dip galvanizing bath, and the cones 12 at both ends of the member 10 are treated. By removing the zinc on the screw of the screw and assembling the sleeve set consisting of the bolt, the sleeve nut and the sleeve, it is possible to produce a complete anticorrosive member set without drilling a hole for assembling the bolt in the member.
한편, 도 3은 본 고안의 일실시예를 나타낸 것으로, 도면에 도시한 바와같이, 볼트(20)에 외연에 끼워져 회전되면서 멤버(10)와 연결볼(60)을 나사결합하는 슬리브(30)에 장공을 설치하지 않고 다수개의 각면(各面)을 내부에 갖도록 구성하고, 볼트(20) 또한 생크(21)의 외주면에서 상기 슬리브(30)의 내부구조와 일치하는 각면을 갖도록 구성하여 슬리브(30)를 회전할 때 볼트(20)도 함께 회전하도록 구성함으로써, 핀과 같은 별도의 연결부재 없이도 트러스 구조물을 완성할 수 있도록 한다.(도 4참조)On the other hand, Figure 3 shows an embodiment of the present invention, as shown in the drawing, the sleeve 30 for screwing the member 10 and the connecting ball 60 while being rotated by being fitted to the outer edge of the bolt 20 It is configured to have a plurality of facets therein without installing a long hole in the inside, and the bolt 20 is also configured to have a facet coinciding with the internal structure of the sleeve 30 on the outer peripheral surface of the shank 21 ( When rotating the bolt 30, the bolt 20 is also configured to rotate together, so that the truss structure can be completed without a separate connecting member such as a pin (see FIG. 4).
이때, 볼트(20)는 머리부를 없이 형성하되, 그 머리부분에 좌나사(24)를 형성한 다음, 너트(25)를 조립하여 조이게 되면, 볼트(20)와 슬리브너트(40)를 조립할 수 있게되므로, 슬리브너트(40)의 안쪽에 형성되는 구멍의 직경을 최소화할 수 있게 된다.At this time, the bolt 20 is formed without the head, the left screw 24 is formed on the head, and then tightened by assembling the nut 25, the bolt 20 and the sleeve nut 40 can be assembled. Therefore, the diameter of the hole formed in the inside of the sleeve nut 40 can be minimized.
이상에서와 같이, 본 고안은 안쪽으로 좌나사가 가공되어 있는 원추형의 콘을 강관의 양끝에 용접하여 멤버를 만들고, 그 멤버의 콘 내부에 결합되는 볼트에는 바깥쪽에 나사가 가공된 슬리브너트 및 슬리브를 순차적으로 끼워 넣어 핀으로 슬리브를 고정한 다음, 콘의 안쪽나사와 슬리브너트의 바깥쪽 나사를 나사 조립토록 함으로서, 멤버의 외면에 볼트를 삽입하기 위한 구멍을 뚫지 않고서도 볼트를 결합할 수 있으며, 이를 통해 표면이 용융아연도금과 같은 부식방지처리가 된 멤버를 얻을 수 있게되는 매우 유용한 고안이다.As described above, the present invention makes a member by welding the cone of the conical cone with the left screw on the inner end of the steel pipe, the bolt is coupled to the inside of the cone of the member, the sleeve nut and the sleeve is screwed on the outside Insert the sequentially to secure the sleeve with a pin, and then screw the inner screw of the cone and the outer screw of the sleeve nut together so that the bolt can be joined without drilling a hole for inserting the bolt into the outer surface of the member. This is a very useful design that allows the surface to obtain a member with corrosion protection such as hot dip galvanizing.
