Description
본 발명은, 체결너트의 고정방법에 관한 것이다.The present invention relates to a fastening nut fastening method.
체결용 관통공을 가진 다수의 구조물을 체결하기 위해서는 체결볼트를 각각의 구조물의 관통공에 삽입하고, 체결볼트의 머리부를 고정도구 혹은 작업자의 손으로 고정한 후, 체결볼트에 대응하는 체결너트를 체결볼트의 나사부에 체결함으로써 이루어진다.To fasten a plurality of structures with fastening holes, insert the fastening bolts into the through holes of each structure, fix the head of the fastening bolts with a fixing tool or a worker's hand, and then fasten the fastening nuts corresponding to the fastening bolts. It is made by fastening to the threaded part of the bolt.
한편, 일예로서, 고정도구 혹은 작업자의 손이 미치지 않는 구조물의 내측에 위치하는 고정부재를 구조물에 체결하는 경우, 체결너트 및 체결볼트 중 어느 하나를 고정부재의 체결용 관통공에 고정시켜 구조물의 내측에 위치시킨 후, 대응하는 체결볼트 혹은 체결너트를 구조물의 관통공을 통해 체결하여 구조물에 고정부재를 결합한다.On the other hand, as an example, when fastening the fixing member or the fastening member located inside the structure that the operator's hand does not reach the structure, by fastening any one of the fastening nut and the fastening bolt to the fastening through-hole of the fastening member of the structure After positioning on the inside, the fastening bolt or fastening nut is fastened through the through hole of the structure to couple the fixing member to the structure.
일반적으로 이러한 고정방법에서는 고정부재의 관통공에 체결볼트를 삽입 후, 체결볼트의 머리부와 고정부재를 상호 용접하여 고정하거나, 고정부재의 관통공에 대응하여 체결너트를 고정부재에 위치시킨 후, 상호 접촉하는 부위의 가장자리를 용접하여 고정하는 방법이 사용된다.In general, in such a fixing method, after inserting the fastening bolt into the through hole of the fixing member, the head of the fastening bolt and the fixing member are welded to each other, or the fastening nut is positioned in the fixing member corresponding to the through hole of the fixing member. For example, a method of welding and fixing the edges of mutually contacting parts is used.
이러한 방법에 의하여, 고정부재의 체결용 관통공에 위치한 체결너트를 고정함으로써, 다른 고정도구 혹은 작업자의 손으로 체결너트를 고정할 필요 없이, 고정된 체결너트에 대응하는 체결볼트만 체결하면 됨으로 작업성을 향상시킬 수 있다.By fixing the fastening nut located in the fastening hole of the fastening member by this method, it is not necessary to fasten the fastening nut with another fastening tool or by the operator's hand, and only the fastening bolt corresponding to the fastening nut needs to be fastened. Can improve the sex.
그런데, 이러한 종래의 체결너트의 고정방법에 있어서는, 체결너트와 고정부재가 같은 재질이어야 하며, 만약 상이한 재질일 경우는 용접성에 문제가 있어 용접이 어렵거나 불가능한 경우가 발생한다. 또한, 용접으로 인해 고정부재에 변형이 발생되며, 작업공수 및 작업비용이 증가되는 등의 문제점이 있다.By the way, in the conventional fastening nut fastening method, the fastening nut and the fixing member should be the same material, if the different materials, there is a problem in the weldability is difficult or impossible to weld. In addition, the deformation occurs in the fixing member due to welding, there is a problem such as an increase in labor and cost.
따라서, 본 발명의 목적은, 재질의 상이함에 관계없이 고정부재와 체결너트를 고정할 수 있으며, 용접으로 인해 발생되는 고정부재의 변형을 막고, 작업이 용이하며, 비용을 절감할 수 있는 체결너트의 고정방법이 제공된다.Therefore, an object of the present invention, it is possible to fix the fixing member and the fastening nut, regardless of the material, preventing the deformation of the fastening member caused by welding, easy to work, can reduce the cost fastening nut The fixing method of is provided.
