약축에 대한 스플릿 티의 기둥-보 접합구조 및 접합방법 {Beam-column connection and detail of split tee in weak axis}Beam-column connection and detail of split tee in weak axis}

본 발명은 약축에 대한 스플릿 티의 기둥-보 접합구조 및 접합방법에 관한 것이다. 더욱 구체적으로, 수평보의 상, 하면의 높이에 상당하는 위치의 기둥 웨브에 보강되는 수평 스티프너(1)의 위치를 소정의 위치만큼 각각 상부 및 하부로이동시킨 약축에 대한 스플릿 티의 기둥-보 접합방법에 관한 것이다.The present invention relates to a column-beam joint structure and a method of joining a split tee to a weak axis. More specifically, the column-beam of the split tee with respect to the weak axis which moved the position of the horizontal stiffener 1 reinforced by the column web of the position corresponding to the height of the upper and lower surfaces of the horizontal beam to upper and lower positions by predetermined position, respectively. It relates to a bonding method.

기둥-보의 접합부는 원활한 응력 전달기구로서의 충분한 변형 능력과 강성 확보가 필수적인 곳으로서 힘의 전달과정이 매우 복잡하다. 특히 기둥과 보로 둘러싸인 부분인 패널존은 수평 스티프너(1)로 보강하지 않을 경우 기둥의 양 플랜지에 국부변형이 발생할 우려가 있다. 이에 기둥-보 접합부에는 기둥 웨브에 수평 스티프너(1)가 일반적으로 보강된다.The beam-to-beam connection is a complex process of force transmission as it is necessary to secure sufficient deformation capacity and rigidity as a smooth stress transmission mechanism. In particular, the panel zone, which is a part enclosed by the pillars and beams, may cause local deformation in both flanges of the pillar when the panel zone is not reinforced with the horizontal stiffener (1). The column-beam connection is thus generally reinforced with a horizontal stiffener 1 in the column web.

그러나 상기한 바와 같이 기둥-보 접합부에서 수평보의 상,하 플랜지의 위치에 상당하는 높이의 기둥 웨브에 수평 스티프너(1)를 보강하는 경우, 약축에 대한 기둥-보 접합이 제한을 받는 문제가 발생한다.However, when reinforcing the horizontal stiffener (1) in the column web of the height corresponding to the position of the upper and lower flanges of the horizontal beam in the column-beam connection as described above, there is a problem that the column-beam connection to the weak axis is limited Occurs.

상기한 문제점 때문에 종래에는 도1에 도시한 바와 같이 공장에서 약축에 대한 기둥-보 접합부의 일부를 미리 용접하여 현장으로 운반하고, 현장에서 수평보의 나머지 부분을 접합하는 방법을 사용해왔다. 그러나 여기에는 우선, 접합부의 용접량이 증가하여 부재가 취성화 되는 문제가 있고 아울러 접합개소가 증가됨으로써 작업량이 늘어나고, 기둥에 접합부의 일부가 연결되어 운송됨으로써 운송이 용이하지 않다는 문제가 있다.Due to the above problems, conventionally, as shown in FIG. 1, a method of welding a part of a pillar-beam joint to a weak axis in a factory in advance and transporting it to a site, and joining the rest of the horizontal beam in the field has been used. However, there is a problem that, firstly, the weld amount of the joint increases and the member becomes brittle, and the amount of work increases due to an increase in the joining point, and there is a problem that transportation is not easy because some of the joint is connected and transported to the column.

본 발명은 상기한 문제점을 해소하기 위하여 안출된 것으로서, 수평 스티프너(1)의 이동으로 약축에 대한 스플릿 티의 기둥-보 접합이 제한을 받지 않도록 하여 접합부의 용접량을 줄이고 접합 개소를 감소시킬 수 있는 약축에 대한 스플릿티의 기둥-보 접합구조 및 접합방법을 제공함을 그 목적으로 한다.The present invention has been made to solve the above problems, the movement of the horizontal stiffener (1) can reduce the welding amount of the joint and reduce the joint location of the split tee beam beam of the split tee to the weak axis is not limited It is an object of the present invention to provide a column-beam joint structure and a method of joining a splitty for a weak axis.

1 : 수평 스티프너 10 : H형강 기둥1: horizontal stiffener 10: H-beam column

20 : H형강 수평보 30 : 스플릿 티20: H-beam horizontal beam 30: split tee

본 발명의 약축에 대한 스플릿 티의 기둥-보 접합구조는 도3에 도시된 바와 같이 H형강 기둥, 스플릿 티, H형강 수평보 및 수평 스티프너로 구성된다.The pillar-beam joint structure of the split tee to the weak axis of the present invention is composed of an H-beam column, a split tee, an H-beam horizontal beam and a horizontal stiffener.

상기 스플릿 티(30)는 T형강을 사용하며, 상기 H형강 기둥의 웨브에 수평으로 부착되어, 기둥과 보를 접합시키는 연결부재의 역할을 한다.The split tee 30 uses T-shaped steel, and is horizontally attached to the web of the H-beam, and serves as a connecting member for joining the pillar and the beam.

상기 수평 스티프너(1)는 강축에 접합되는 수평보의 플랜지 부분의 응력을 기둥의 웨브에 원활하게 전달하고, 기둥 플랜지의 국부좌굴을 방지하기 위하여 설치되는 것으로서, 상기 H형강 기둥(10)에 접합되는 H형강 수평보(20)의 상,하면의 높이에 상당하는 위치에서 각각 상부 및 하부로 소정의 거리만큼 이동시켜 설치된다.The horizontal stiffener (1) is installed to smoothly transfer the stress of the flange portion of the horizontal beam joined to the steel shaft to the web of the pillar, and to prevent local buckling of the pillar flange, bonded to the H-beam pillar (10) It is installed by moving a predetermined distance upward and downward, respectively, at a position corresponding to the height of the upper and lower surfaces of the H-beam horizontal beam 20 to be.

상기한 소정의 거리는 기둥의 웨브에 스플릿 티(30)를 부착하기 위해 필요한 최소한의 고력볼트 체결작업 공간을 확보할 수 있는 거리를 말한다. 이렇게 수평 스티프너의 위치를 이동시킴으로써 약축에 대한 스플릿 티의 기둥-보 접합을 용이하게 하고, 수평보를 현장에서 한 번에 접합할 수 있어 접합개소가 기존의 4개소에서 2개소로 줄어든다. 또한 스플릿 티(30)가 바로 패널 존에 부착되므로 패널 존의 체적이 증가하여 접합부의 강성 및 변형능력도 증가된다.The predetermined distance refers to a distance capable of securing a minimum high-strength bolt fastening work space required for attaching the split tee 30 to the web of the pillar. By shifting the position of the horizontal stiffener in this way, the column-beam joining of the split tee with respect to the weak axis is facilitated, and the horizontal beam can be joined at once in the field, and the joining points are reduced from the existing four places to two places. In addition, since the split tee 30 is directly attached to the panel zone, the volume of the panel zone is increased to increase the rigidity and deformation capacity of the joint.

수평보(20)는 보의 상,하부 플랜지가 상기 스플릿 티(30)의 웨브에 고력볼트로 연결되어 기둥에 수평으로 접합된다.Horizontal beam 20 is the upper and lower flanges of the beam is connected to the web of the split tee 30 with high-strength bolt is horizontally bonded to the pillar.

H형강 기둥의 강축에 접합되는 수평보의 접합방법은 수평 스티프너에 의한 제한이 없으므로 용접접합, 고력볼트 접합 등 현장상황에 따라 어느 것이나 가능하다.The method of joining the horizontal beam to the steel shaft of the H-beam column is not limited by the horizontal stiffener, so that any one can be used depending on the site, such as welding or high-strength bolt.

약축에 대한 스플릿 티의 기둥-보 접합방법은, 먼저 H형강 기둥(10)에 접합될 수평보의 상,하면의 높이에 상당하는 위치에서, 스플릿 티(30)를 기둥 웨브에 부착하기 위해 필요한 최소한의 고력볼트 체결작업 공간을 확보할 수 있는 거리만큼 각각 상부 및 하부로 이동시킨 위치에, 수평 스티프너(1)를 기둥의 웨브와 양 플랜지에 용접하여 설치한다.The pillar-beam joining method of the split tee with respect to the weak axis is first required for attaching the split tee 30 to the pillar web at a position corresponding to the height of the upper and lower surfaces of the horizontal beam to be joined to the H-beam column 10. The horizontal stiffener (1) is welded to the web and both flanges of the column and installed at the position moved to the upper and lower positions, respectively, by a distance to secure a minimum high-strength bolt fastening work space.

상기 작업 후 스플릿 티(30)의 플랜지 부분을 기둥의 웨브에 고력볼트로 연결하여 수평으로 부착하고, 상기 스플릿 티(30)의 웨브에 H형강 수평보(20)의 플랜지를 고력볼트로 연결하여 상기 H형강 기둥에 접합시킨다.After the operation, the flange portion of the split tee 30 is connected to the web of the column by high-strength bolt, and horizontally attached, and the flange of the H-beam horizontal beam 20 to the web of the split tee 30 by high-strength bolt. Joined to the H-beams.

본 발명의 약축에 대한 스플릿 티의 기둥-보 접합구조 및 접합방법은 기둥 웨브에 보강되는 수평 스티프너(1)의 위치를 이동시킴으로써, 약축에 대한 기둥-보의 접합방법의 제한을 해소하고, 스플릿 티 접합에 의해 수평보를 현장에서 한 번에 기둥에 접합할 수 있어 접합개소를 종래의 4개소에서 2개소로 감소시킬 수 있을 뿐만 아니라 접합부의 용접량을 감소시켜 부재의 취성화를 방지할 수 있다.The column-beam joining structure and the joining method of the split tee with respect to the weak axis of the present invention eliminate the limitation of the method of joining the column-beam to the weak axis by moving the position of the horizontal stiffener 1 which is reinforced to the column web. By tee joining, horizontal beams can be joined to a column at a time in the field, so that the joining points can be reduced from two places in the prior art, and the welding amount of the joining parts can be reduced to prevent brittleness of the members. .
