Description

철골보의 보강구조{Reinforcement structure of steel beam}Reinforcement structure of steel beams

본 발명은 건축구조물의 시공시, 기둥과 연결되는 철골보의 보강구조에 관한 것으로서, 좀더 상세하기는 양단부의 플랜지와 중앙의 연결플랜지 연결시기키 위해보강부재를 구비하여 강접함으로써, 상기와 같이 강접하는 부분에 집중되는 힘을 보강부재에 적용되는 수평 및 수직전단 응력에 의해 양단부의 플랜지로 전달되어, 양단부의 플랜지와 중앙의 연결플랜지의 접합되는 접합부의 접합강도를 향상시키고, 모멘트접합에 의해 발생하는 휨 및 처짐 현상을 방지할 수 있는 철골보의 보강구조에 관한 것이다.The present invention relates to the reinforcement structure of the cheolgolbo connected to the pillars during construction of the building structure, in more detail is to be in rigid contact with the reinforcing member provided with a reinforcing member for connecting the flange and the connection flange in the center of both ends, The force concentrated on the part is transmitted to the flanges at both ends by horizontal and vertical shear stresses applied to the reinforcing members, thereby improving the joint strength of the joints joined at the flanges at both ends and the connecting flange at the center, and generated by moment bonding. The present invention relates to a reinforcement structure of steel cheolgolbo, which can prevent bending and sagging.

일반적으로 철골공사에 사용되는 철골보 접합방법은 크게 모멘트접합과 전단 접합이 있다.In general, the cheolgolbo joining method used in steel frame construction is largely moment bonding and shear bonding.

모멘트 접합은 접합부에서 발생하는 모멘트로 외력에 저항하는 것, 즉 모멘트 저항시스템으로 말하고, 전단접합(예:핀접합)은 트러스와 같은 구조물에서 부재의 접합부에 모멘트가 발생하지 않도록 접합하는 방법을 말한다.Moment bonding refers to the moment generated at the joint to resist external forces, that is, the moment resistance system, and shear bonding (eg pin bonding) refers to the method of joining the joint of a member such that the moment does not occur in a structure such as a truss. .

각각의 접합방법을 H형강보로 예를들어 설명하면,For example, each bonding method is described as an H-beam.

전단접합(Shear Connection, Simple Connection, Pin Connection, Hinge Connection)은 H형강의 웨브(Web)만 볼트 등으로 체결시키고 플랜지(Flange)는 연결시키지 않음으로써, 보의 회전을 허용한 접합형태를 말하고,Shear connection (Shear Connection, Simple Connection, Pin Connection, Hinge Connection) refers to the type of connection that allows the rotation of the beam by fastening only the web of H-beams with bolts and not connecting the flanges.

모멘트접합(Moment Connection, Rigid Connection)은 H형강의 웨브(Web) 뿐만 아니라 플랜지(Flange)를 볼트 및 강접으로 강하게 연결시켜 보의 회전을 구속시킨 접합형식 말한다.Moment connection (rigid connection) refers to the joint type that restricts the rotation of the beam by connecting the flange of the flange as well as the web of the H-beam and the flange.

상기와 같은 모멘트 접합으로 인해 철골보에 작용하는 모멘트를 살펴보면, 철골보의 상면이 압축되어, 하면이 인장되는 정모멘트와, 철골보의 하면이 압축되어, 상면이 인장되는 부모멘트가 작용하게 된다.Looking at the moment acting on the cheolgolbo due to the moment bonding as described above, the upper surface of the cheolgolbo is compressed, the positive moment is tensioned the lower surface, and the lower surface of the cheolgolbo is compressed, the parent moment acts to tension the upper surface.

각각의 정모멘트와 부모멘트가 하중에 의해 작용되는 힘은 중앙부의 정모멘트보다 양단부의 부모멘트가 크게 발생된다.The force exerted by the loads of the constant moment and the parent moment is greater in the parent moments at both ends than in the center moment.

종래에 철골보의 제작에 있어서, 철골보의 양단부와 중앙부를 동일한 높이로 평행하게 제작하게 되면, 도 1 내지 도 2에서 도시한 바와 같이, 양단부(n)의 힘의 작용으로 인해 중앙부(p)의 무게가 증가하게 되어, 상기 중앙부(p)가 하방향으로 처짐이 가중되거나 파손됨으로, 철골보로써의 기능을 수행할 수 없게 되며, 경제적인 손실을 가져오는 문제점이 발생하였다. In the conventional production of cheolgolbo, if both ends and the center portion of the cheolgolbo produced in parallel to the same height, as shown in Figures 1 to 2, the weight of the central portion (p) due to the action of the force of both ends (n) Since the central portion (p) is increased or broken down in the downward direction, it is unable to perform a function as a cheolgolbo, causing a problem of economic loss.

상기 종래의 문제점을 해결하기 위한 본 발명의 목적은 철골보의 양단부를 연결하기 위해 마련된 연결플랜지를 강접하는데 있어서, 철골보의 상부과 연결플랜지의 상부를 수평하게 위치한 다음, 철골보의 일측면과 연결플랜지의 일측면이 접촉되는 접합부를 강접한 후, 상기 접합부에 추가로 보강부재를 접합함으로써, 접합부를 견고히 지지하는 동시에 접합강도를 향상시키며, 모멘트접합에 의해 발생하는 휨 및 처짐 현상을 방지할 수 있는 철골보의 보강구조를 제공하는 것이다.
