본 고안은 이중강관기둥의 결합구조에 관한 것으로서, 더욱 상세하게는 각형강관부재를 효율적으로 건축구조용 기둥부재로 사용할 수 있도록 한 것이다.The present invention relates to a coupling structure of a double steel pipe column, and more particularly, to enable the use of a square steel pipe member as a structural structural pillar member.
최근에 강형강관부재를 중저층 및 고층건물의 기둥부재로 사용할 경우 강축과 약축의 구별이 없으므로 구조적인 성능이 기존의 H형강기둥에 비해 우수하다는 것이 널리 알려져 있다.Recently, when the steel member is used as the pillar member of the middle and high floors, it is widely known that the structural performance is superior to that of the conventional H-beam because there is no distinction between the steel shaft and the weak shaft.
종래에 각형강관부재를 기둥부재로 사용한 경우에 보(2)와 기둥(1a)의 접합부는 제1a도, 1b, 1c도와 같이 관통과 내측 및 외측다이어프램방식이 주로 사용되고 있는데, 이러한 다이어프램은 보(2)에 작용하는 하중(P) 및 모멘트(M)를 기둥(1a)에 전달하는 역할을 하게된다. 그러나 기존 방식의 다이어프램의 제작 및 설치에 있어서 제2도와 같은 보(2)와 기둥(1a)접합부의 국부좌굴을 방지하기 위해 접합부 위치에 다이어프램을 제작하여 층별로 설치해야 하는 시공 및 제작상 고난이도의 기술이 요구되고 있어서 자동 용접 로봇과 보-기둥 접합부 반전기와 같은 자동화 기계에 의존하여 다이어프램 유닛을 별도로 제작해야 하는 문제점이 있었다.Conventionally, when the square steel pipe member is used as the pillar member, the connection between the beam 2 and the pillar 1a is mainly used in the through and inner and outer diaphragms as shown in FIGS. 1a, 1b, and 1c. 2) the load (P) and the moment (M) acting on the role to transfer to the column (1a). However, in the fabrication and installation of the conventional diaphragm, the construction and production of high difficulty in the construction and production of the diaphragm at the junction location to install locally to prevent local buckling of the beam 2 and the pillar 1a junction as shown in FIG. There is a problem in that a diaphragm unit has to be manufactured separately depending on an automated machine such as an automatic welding robot and a beam-column junction inverter.
본 고안은 상기한 제반문제점을 해결하기 위한 것으로서, 본 고안은 각형 강관부재를 좌굴성능이 뛰어난 효율적인 건축구조용 기둥부재로 사용할 수 있도록 공간을 효과적으로 활용할 수 있을 뿐만 아니라, 건물의 전체적인 연성을 증가시켜 급격한 건물의 붕괴를 방지할 수 있는 이중강관기둥의 결합구조를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention can not only effectively use the space to use the square steel pipe member as an efficient structural structural pillar member with excellent buckling performance, but also increase the overall ductility of the building The purpose is to provide a combined structure of double steel pipe pillars to prevent the collapse of buildings.
상기한 목적을 달성하기 위해 본 고안은 복수개의 보(2)가 연결되는 외측 각형강관(1)과, 상기 외측각형강관(1)에 삽입되어 좌굴발생이 방지되도록 구속해주는 내측각형강관(3)과, 상기 내측 및 외측각형강관(3)(1)에 결합되는 엔드플레이트(4)로 구성된 이중강관기둥의 결합구조이다.In order to achieve the above object, the present invention provides an outer angular steel pipe 1 to which a plurality of beams 2 are connected, and an inner angular steel pipe 3 inserted into the outer angular steel pipe 1 to restrain the buckling from occurring. And, it is a coupling structure of the double steel pipe pillar consisting of the end plate (4) coupled to the inner and outer square steel pipe (3) (1).
이하 본 고안의 일실시예를 첨부도면 제3도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 3.
제3도는 본 고안을 나타낸 분해 사시도로서, 외측각형강관(1)의 둘레면이 복수개의 보(2)가 연결되어 있고, 상기 외측각형강관(1)의 내부면 중앙에는 내측강형강관(3) 하단의 모서리가 위치되도록 삽입되며, 상기 내측 및 외측각형강관(3)(1)의 상하단에는 엔드플레이트(4)가 결합되어 구성된다.3 is an exploded perspective view showing the present invention, the circumferential surface of the outer square steel pipe (1) is connected to a plurality of beams (2), the inner steel tube (3) in the center of the inner surface of the outer square steel pipe (1) The bottom edge is inserted so that the upper and lower ends of the inner and outer angular steel pipes 3 and 1 are coupled to the end plate 4.
이와같이 구성된 본 고안은 제3도에 나타낸 바와같이, 외측각형강관(1)의 내면중앙에 내측각형강관(3)하단의 모서리가 위치되도록 삽입되고, 상기 내측 및 외측각형강관(3)(1)의 상하단에는 엔드플레이트(4)가 결합되므로 접합부에 작용하는 하중(P) 및 모멘트(M)가 보(2)의 플랜지 및 웨브면을 따라 상기 외측각형강관(1)면으로 전달되어 제2도와 같이 외측각형강관(1)면을 좌굴시키고자 하는 경향을 내측각형강관(3)의 모서리 부위에서 선형태로 외측각형강관(1)면의 하증전달부위를 지지하게 되므로 인해 상기 외측각형강관(1)면에 좌굴이 발생되지 않도록 구속해 줄 수 있게 된다.The present invention configured as described above is inserted in such a way that the bottom edge of the inner corner steel tube 3 is positioned at the center of the inner surface of the outer square steel tube 1, and the inner and outer square steel tubes 3 and 1 as shown in FIG. The upper and lower ends of the end plate 4 are coupled to each other, so that the load P and the moment M acting on the joint are transferred to the outer angular steel pipe 1 surface along the flange and web surface of the beam 2 to the second degree. As described above, the tendency of buckling the outer angular steel pipe 1 surface is supported by the lower transfer portion of the outer angular steel pipe 1 surface in a linear form at the corner of the inner angular steel pipe 3. It is possible to restrain the buckling from occurring.
또한, 현장에서 본 고안의 단위 이중강관부재를 이용하여 건물의 기둥을 제작하는 경우에는 내, 외측각형강관(3)(1)의 상,하단에 결합된 엔드플레이트(4)를 이용하여 보울트 연결만 하면 되므로 공기의 단축 및 품질관리의 효율성을 얻을 수 있게 된다.In addition, when manufacturing the pillar of the building using the unit double steel pipe member of the present invention in the field, the bolt connection using the end plate (4) coupled to the upper and lower ends of the inner, outer lateral steel pipe (3) (1) Since it is necessary to achieve the shortening of air and the efficiency of quality control.
또한, 단위 이중강관기둥부재의 길이를 현장에서 변경해야 하는 경우에는 단위 기둥부재를 요구하는 길이만큼 절단하여 현장에서 조립 및 용접시공하면 되므로 단위 기둥부재의 길이를 현장에서 조립 및 용접시공하면 되므로 단위 기둥부재의 길이를 현장에서 자유자재로 조절할 수 있게 된다.In addition, when the length of the unit double steel tube pillar member is to be changed in the field, the unit pillar member may be cut to the required length, and then assembled and welded on site, so the unit pillar member may be assembled and welded on site. The length of the pillar member can be adjusted freely in the field.
이상에서와 같이, 본 고안은 이중강관부재를 사용하므로써, 기둥부재의 크기가 감소되어 공간을 효율적으로 활용할 수 있으며, 구조적인 측면에서도 외측각형강관(1)의 파괴 이후에도 내측각형강관(3)이 적절히 하중을 지지하게 되므로 건물의 전체적인 연성을 증가시켜 급격한 건물의 붕괴를 방지할 수 있을 뿐만 아니라, 기존의 각형강관부재를 사용하여 제작할 수 있으므로 인해 제작 등과 같은 불필요한 작업을 절감시킬 수 있는 매우 유용한 고안이다.As described above, the present invention by using a double steel pipe member, the size of the pillar member is reduced to utilize the space efficiently, even in the structural aspect of the inner square steel pipe (3) after the destruction of the outer square steel pipe (1) As it supports the load properly, it can increase the overall ductility of the building to prevent sudden collapse of the building, and it can be manufactured by using the existing square steel pipe member, so it is very useful to reduce unnecessary work such as manufacturing. to be.
