Description

용접 절점구조{Welding nodal structure}Welding nodal structure

본 발명은 용접 절점구조에 관한 것으로서, 특히 용접절점구의 외측에 형성된 절점요부에 절점돌부가 형성된 각각의 용접강부재가 맞대어져 용접이음으로 결합되어지도록 한 것이다.The present invention relates to a welded joint structure, in particular, each welded steel member having a joint portion formed at a joint recess portion formed on the outer side of a welded joint so that the welded steel members are coupled by welded joints.

일반적으로 벽체 또는 지붕을 갖는 강구조물은 원형강관, 각형강관 및 H형강 등(이하, "강부재"라 함)을 이용하여 시공되어지게 되고, 강부재는 벽체 또는 지붕에 소요되는 길이 만큼 절단된 상태에서 절단된 부위가 서로 맞대어지도록 한 후 볼트(리벳) 또는 용접이음을 통해 결합되어지도록 구성되어 있다.Generally, a steel structure having a wall or a roof is constructed using a round steel pipe, a rectangular steel pipe, an H-shaped steel or the like (hereinafter referred to as "steel member"), and the steel member is cut So as to be brought into contact with each other and then to be connected through bolts (rivets) or welded joints.

벽체 시공에 필요한 벽체용 강부재는 절단된 하부에 관통홀이 형성된 바닥 플랜지가 형성되어 앵커볼트에 의하여 바닥기초에 맞대어지게 설치되어지고, 절단된 상부에 관통홀을 갖는 루프 플랜지가 형성되어 루프(지붕)의 가장자리에 맞대어져 볼트 또는 용접이음으로 결합되게 설치된다.A steel member for a wall used for a wall is formed by forming a bottom flange having a through hole at the cut bottom and being fitted to the bottom of the floor by means of an anchor bolt and forming a loop flange having a through hole at the cut top, Roof) and are joined together by bolts or welded joints.

루프 시공에 필요한 루프용 강부재는 일측단 또는 타측단이 각각 루프 플랜지에 맞대어지는 관통홀을 갖는 맞대기 플랜지가 형성되어 볼트 또는 용접이음으로 결합되어지고, 맞대기 플랜지와 대응되는 루프용 강부재의 일측단 또는 타측단은 맞대어지는 면에 해당하는 형태와 각도 만큼 절단되어지도록 하고, 절단된 각각의 절단면이 맞대어져 용접이음으로 결합되어지게 설치된다.A steel member for a loop necessary for a loop construction is formed by a bolt or a welded joint formed with a butt flange having a through hole through which one end or the other end abuts against the roof flange, The end or the other end is cut by a shape and an angle corresponding to the face to be abutted, and the respective cut surfaces are fitted to each other so as to be joined by welding.

그러나 벽체용 강부재에 있어 절단된 상부에 루프 플랜지를 가공하여 용접이음으로 결합되어지도록 하거나, 루프용 강부재에 있어 각각 맞대어지는 면을 절단하여 용접이음으로 결합되도록 하는 과정에서 작업 공정수의 증가로 인하여 시공기간이 길어지는 가운데 시공 비용에 증가되는 문제점이 있었다.However, in the steel member for the wall, the loop flange is formed on the cut upper part so as to be joined by welded joint, or in the process of cutting the facing faces of the steel members for loop, The construction time is lengthened and the construction cost is increased.

또한 벽체 또는 루프 형태가 돔의 형태 등 둥근 형태의 구조를 갖게 될 경우, 모든 벽체용 강부재 또는 루프용 강부재가 정확히 맞대어지도록 정밀 절단 가공 및 그에 따른 정밀 이음 작업이 소요됨으로써, 전기한 바와 같은 동일한 문제점이 있었다.Further, when the wall or the loop shape has a round shape such as a dome shape, it is necessary to perform precise cutting and precise joining operations so that the steel members for all the walls or the steel members for the loops can be accurately brought into contact with each other. There was the same problem.

그리고 벽체 또는 루프 형태가 일정한 곡률을 갖지 않고 임의 곡율을 가질 경우, 작업이 더욱 지연되는 또 다른 문제점이 있었다.If the wall or loop shape does not have a constant curvature but has an arbitrary curvature, there is another problem that the work is further delayed.

본 발명은 벽체용 강부재 또는 루프용 강부재에 있어 각각 맞대어지는 면을 절단하여 용접이음으로 결합되도록 하는 과정에서 작업 공정수를 줄여 시공기간을 단축시킬 수 있도록 하는 가운데 시공비용을 줄일 수 있도록 하고, 아울러 벽체 또는 루프 형태가 일정한 곡률을 갖는 돔 형태이거나 임의 곡율을 갖는 돔 또는 파도형태의 상,하부 원형 곡율을 갖는 루프 형태일 경우에도 작업이 용이하게 이루어질 수 있도록 한 것이다.The present invention reduces the number of work processes and shortens the construction period in the process of cutting the facing surfaces of the steel member for a wall or the steel member for a loop and joining them by welded joints, , And the work can be easily performed even when the wall or loop shape is a dome shape having a constant curvature or a loop shape having an upper or lower circular curvature in the form of a dome or a wave having a certain curvature.
