Description

체결장치{COUPLING DEVICE}Fastening Device {COUPLING DEVICE}

본 발명은 체결장치에 관한 것으로, 특히 협소한 장소에 배치되는 제 1,2부재를 외측 일방향에서 간편하게 체결시킴과 아울러, 제 1,2부재를 견고하게 상호 연결시킬 수 있도록 그 구조가 개선된 체결장치에 관한 것이다.The present invention relates to a fastening device, in particular, the fastening of the structure is improved so that the first and second members, which are arranged in a narrow place, can be easily fastened in one outer direction, and the first and second members can be firmly interconnected. Relates to a device.

일반적으로 H빔 형태의 보 또는 패널 형태의 제 1부재와 제 2부재를 연결시키는 통상의 방법은, 볼트와 너트를 이용한 체결식 고정구조를 채택하고 있다.In general, the conventional method of connecting the first member and the second member in the form of a beam or panel in the form of an H beam adopts a fastening type fixing structure using bolts and nuts.

그 체결식 고정구조의 결합방식은 제 1,2부재에 결합공을 형성시킨 후에, 볼트를 제 1,2부재의 결합공을 관통시키고, 관통된 볼트의 단부에 너트를 체결하는 방식을 갖는다.The coupling method of the fastening type fastening structure has a method of forming a coupling hole in the first and second members, then passing the bolt through the coupling hole of the first and second members, and fastening the nut to the end of the penetrated bolt.

그런데, 제 1부재가 벽면과 근접된 위치에 배치될 경우에는 벽면과 제1부재 사이의 공간이 협소하므로, 볼트 또는 너트를 체결하기 어려운 문제점이 있었다.By the way, when the first member is disposed in a position close to the wall surface, since the space between the wall surface and the first member is narrow, it is difficult to fasten the bolt or nut.

예컨대, 한국공개특허공보 10-2010-1516호에 개시되고 도 11 및 도 12를 참조하면, 가설 흙막이 공사에 사용되는 버팀보(30)를 사각 강관 형태로 구성하고, 띠장(20)과 버팀보(30)의 연결부에는 경사 형태로 위치하는 경사버팀보(40)가 체결볼트(50)로 체결되도록 한 것이다.For example, disclosed in Korean Patent Laid-Open Publication No. 10-2010-1516 and referring to FIGS. 11 and 12, the brace 30 used for temporary soil construction is configured in the form of a square steel pipe, and the strip 20 and the brace 30 are formed. ), The inclined brace 40 positioned in the inclined form is to be fastened to the fastening bolt (50).

그리고, 경사버팀재(40)의 양단에는 체결공(41)(41')이 형성된 고정판(42)(42')이 결합되고, 고정판(42)(42')이 버팀보(30)의 표면에 밀착되며, 상기의 고정판(42)(42')에는 버팀보(30)와 견고하게 고정하기 위한 체결공(41)(41')을 관통하도록 되어 있다.In addition, fixing plates 42 and 42 'having fastening holes 41 and 41' are coupled to both ends of the inclined support material 40, and the fixing plates 42 and 42 'are formed on the surface of the support 30. In close contact with each other, the fixing plates 42 and 42 ′ penetrate the fastening holes 41 and 41 ′ for firmly fixing the brace 30.

그런데, 버팀보(30)가 사각 강관 형태(통형)로 형성되어 강관 내부로 작업자의 손이 들어갈 수 없게 되므로, 버팀보(30)를 고정시키기 위한 너트의 채용이 불가능하다.By the way, since the brace 30 is formed in a rectangular steel pipe form (cylindrical) to prevent the operator's hand into the steel pipe, it is impossible to employ a nut for fixing the brace 30.

이에 따라서 버팀보(30)에는 경사버팀재(40)의 체결공(41)(41')과 대응하는 체결나사공(31)(31')을 형성하여 체결볼트(50)로 나사 체결하여야 한다.Accordingly, the brace 30 has to be fastened to the fastening holes 41 and 41 ′ of the inclined brace material 40 to form the fastening screw holes 31 and 31 ′ to be screwed with the fastening bolt 50.

그러나, 이 경우에는 공사중 버팀보(30) 등의 충격 및 진동 등으로 나사풀림이 발생할 수 있어 안전사고가 염려된다.However, in this case, the screw loosening may occur due to the shock and vibration of the brace 30 and the like during construction, which may cause safety accidents.

본 발명은 상기한 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 그 목적은 협소한 공간에 배치된 제 1,2부재들간의 상호 연결 및 고정을 외측 일방향에서 용이하게 체결할 수 있도록 그 구조가 개선된 체결장치를 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an easy structure for fastening the interconnection and fixing between the first and second members disposed in a narrow space in one outer direction.
