철골보 접합부{STEEL BEAM JOINT}Cheolgolbo Joint {STEEL BEAM JOINT}

본 발명은 철골 구조에서 이음판의 사용을 최소화하면서 인접 보를 상호 결합하기 위한 철골보 접합부에 대한 것이다.
The present invention relates to a cheolgolbo joint for mutually joining adjacent beams while minimizing the use of the joint plate in the steel structure.

공장, 창고, 고층건물 등의 큰 공간을 필요로 하는 건축물에는 장스팬의 대형 철골 구조가 많이 적용되고 있으며, 철골 구조를 구성하는 각 부재는 부재 제작 전에 요구되는 설계응력에 맞추어 부재 설계를 먼저 실시한 다음, 설계된 치수대로 각 부재를 개별 생산하는 과정을 통하여 제작된다. Large structures of long spans are applied to buildings that require large spaces such as factories, warehouses, and high-rise buildings, and each member of the steel structure is designed to meet the design stress required before the member is manufactured. Next, it is produced through the process of producing each member individually in the designed dimensions.

이때 H 형강 등 기존 형강재 이외에도 최적 설계를 위한 구조재로 강판을 용접하여 성형한 조립용접보가 널리 사용되고 있으며, 조립용접보는 공장 제작 후 현장에서 이음판을 이용하여 볼트 또는 용접 조립하는 방법으로 서로 접합한다.At this time, in addition to the existing shaped steels such as H-shaped steel, assembly welding beams formed by welding steel sheets as a structural material for optimum design are widely used.The welding welding beams are joined together by bolts or welding assembly using a joint plate at the site after manufacturing the factory. .

도 1의 (a)와 (b)는 각각 종래 춤이 동일한 철골보(10)의 접합부를 도시하는 정면도 및 사시도이고, 도 2의 (a)와 (b)는 각각 종래 춤이 다른 철골보(10, 11)의 접합부를 도시하는 정면도 및 사시도이다.1 (a) and (b) are a front view and a perspective view respectively showing a joint of the cheolgolbo 10, the conventional dance is the same, Figures 2 (a) and (b) are respectively different cheolgolbo 10 , 11) is a front view and a perspective view showing the junction of FIG.

종래에는 도 1에서와 같이 춤이 동일한 철골보(10)의 경우 인접 철골보(10)의 상하부 플랜지 및 웨브를 연결하는 접합플레이트(20)를 덧댄 다음 이들을 상호 볼트 결합하였다. 그리고 도 2에서와 같이 춤이 다른 철골보(10, 11)인 경우에는 춤이 작은 보(11)의 응력을 춤이 큰 보(10)에 전달하기 위하여, 춤이 작은 보(11)의 플랜지 위치에 대응하는 위치의 춤이 큰 보(10) 내에 거셋플레이트(30)를 결합하고, 이 거셋플레이트(30) 단부에 다른 거셋플레이트(30)를 수직 방향으로 접합하였다. Conventionally, in the case of the same cheolgolbo 10 as shown in Figure 1 padded the joint plate 20 for connecting the upper and lower flanges and the web of the adjacent cheolgolbo 10 and then bolted to each other. And when the dance is different cheolgolbo (10, 11) as shown in Figure 2 in order to transfer the stress of the small beam 11 of the dance to the large beam 10, the flange position of the small dance of the dance 11 The gusset plate 30 was coupled into the large beam 10 at the position corresponding to the other, and the other gusset plate 30 was joined to the end of the gusset plate 30 in the vertical direction.

그러나 상기와 같이 접합플레이트(20)나 거셋플레이트(30)를 이용한 기존의 철골보 접합 방법은 플레이트 가공과 볼트 결합공 작업, 현장에서의 별도의 조립 공정 등으로 인하여 강재량, 볼트량, 현장 조립 공정 등과 같은 많은 경제적, 공기적, 품질적 문제를 안고 있었다. 또한, 접합부 결합시 구조적 안전성에 문제가 발생할 수 있는 단점이 있었으며, 특히, 거셋플레이트(30)를 이용한 춤이 다른 철골보의 접합은 접합 상세가 복잡하고, 시공이 불편하였다.However, the existing steel cheolgolbo joining method using the joining plate 20 or gusset plate 30 as described above is a steel material, bolt amount, field assembly process due to the plate processing and bolt joint hole work, separate assembly process in the field There were many economic, air and quality issues such as these. In addition, there was a disadvantage that a problem may occur in the structural safety when joining the joint, in particular, the joint of the different cheolgolbo using the gusset plate 30, the joint details are complicated, the construction was inconvenient.

한편, 종래 보, 거더 등의 수평부재를 접합하는 경우에는 먼저 설치된 일측 철골보 일단에 인접 철골보인 타측 철골보의 일단을 연결하였다.On the other hand, when joining a horizontal member, such as conventional beams, girders, was connected to one end of the other side cheolgolbo first adjacent one end of the cheolgolbo installed first.

그러나 일측 철골보의 측면에서 타측 철골보를 수평 방향으로 이동시키면서 결합하는 경우, 철골보의 수평 및 수직 방향 중심을 모두 맞추면서 작업하기가 곤란한 문제점이 있었다. 왜냐하면, 인접 철골보의 접합 과정은 고소 작업으로 이루어지는데, 철골보를 양중하여 일측 철골보의 단부와 수평 및 수직 중심을 맞추는 작업시 타측 철골보의 단부가 상하좌우로 이동하므로 위험하기 때문이다.
However, when combining the other side cheolgolbo in the horizontal direction from the side of one side cheolgolbo, there was a problem that it is difficult to work while matching both the horizontal and vertical center of the cheolgolbo. Because, the joining process of the adjacent cheolgolbo is made of a sue operation, because the end of the other cheolgolbo moves up, down, left, and right during the work of aligning the end of one cheolgolbo horizontally and vertically by lifting the cheolgolbo.

Is provided to the cheolgolbo junction, characterized in that coupled to be mounted on top of the protruding lower flange of the first member.

다른 바람직한 실시예에 따른 본 발명은 상기 제2부재는 제1부재와 춤이 동일하고 제1부재와 결합되는 단부의 상부 플랜지가 제1부재 방향으로 돌출 형성되고, 상기 제2부재의 돌출된 상부 플랜지는 제1부재의 상부 플랜지 상부에 거치되도록 결합되는 것을 특징으로 하는 철골보 접합부를 제공한다. According to another exemplary embodiment of the present invention, the second member has the same dance as the first member, and an upper flange of the end joined to the first member protrudes toward the first member, and the protruding upper portion of the second member. The flange provides a cheolgolbo joint, characterized in that coupled to be mounted on top of the upper flange of the first member.

또 다른 바람직한 실시예에 따른 본 발명은 상기 제2부재의 춤이 제1부재의 웨브 높이(d)보다 t만큼 작고, 두께가 t인 연결플레이트가 일측 상면은 제1부재의 상부 플랜지 하면에 결합되고 타측 하면은 제2부재의 상부 플랜지 단부 상면에 결합되는 것을 특징으로 하는 철골보 접합부를 제공한다.According to another preferred embodiment of the present invention, the dance of the second member is smaller than the height d of the web of the first member by t, and the connection plate having a thickness of t is connected to the lower surface of the upper flange of the first member. And the other lower surface provides a cheolgolbo junction, characterized in that coupled to the upper surface of the upper flange end of the second member.

또 다른 바람직한 실시예에 따른 본 발명은 상기 제2부재는 거더이고, 상기 제1부재는 거더 또는 브라켓인 것을 특징으로 하는 것을 특징으로 하는 철골보 접합부를 제공한다.According to another preferred embodiment of the present invention, the second member is a girder, and the first member provides a cheolgolbo joint, characterized in that the girder or a bracket.

상기와 같은 본 발명에 따르면 다음과 같은 효과가 있다.According to the present invention as described above, the following effects can be obtained.

첫째, 일측 철골보의 플랜지 상부에 타측 철골보의 플랜지를 위치시켜 인접 철골보의 플랜지 상하면을 직접 결합하기 때문에, 별도의 이음판이 불필요하다. 따라서 강재량 및 볼트량 절감, 현장 조립 공정 생략으로 인한 경제성 향상, 공기 단축, 고품질의 접합부 양산이 가능하다.First, since the flange of the other side cheolgolbo is positioned directly on the flange of one side cheolgolbo directly coupled to the upper and lower flanges of the adjacent cheolgolbo, a separate joint plate is unnecessary. Therefore, it is possible to reduce the amount of steel and bolts, improve economics by omitting the field assembly process, shorten the air, and mass-produce high-quality joints.

둘째, 일측 철골보의 웨브 높이보다 타측 철골보의 춤이 t 만큼 작을 경우, 인접 철골보의 상부 플랜지 사이의 공간을 통하여 일측 철골보의 상부 플랜지 하부 및 타측 철골보의 상부 플랜지 상부 사이에 두께 t인 연결플레이트의 양단을 용이하게 위치시킬 수 있다. 따라서 간단한 시공으로 응력 전달을 확실하게 할 수 있는 장점이 있다. Second, if the dance of the other cheolgolbo is t smaller than the web height of one cheolgolbo, t between both ends of the upper plate of the upper cheolgolbo and the upper flange of the other cheolgolbo through the space between the upper flanges of the adjacent cheolgolbo Can be easily located. Therefore, there is an advantage that can be ensured stress transmission by a simple construction.

셋째, 인접 철골보의 춤이 동일한 경우 뿐만 아니라 춤이 상이한 경우에도 적용할 수 있어, 실내 천정고를 높일 수 있다.Third, it is possible to apply not only when the dance of the adjacent cheolgolbo is the same, but also when the dance is different, it is possible to increase the indoor ceiling height.

넷째, 설계 응력에 따른 부재 단면의 최적 설계시, 인접 부재 상호 간에 부재 단면의 크기 또는 두께가 상이하여 인접 철골보의 위치가 동일 평면에 있지 아니하더라도 적용할 수 있다. 따라서 단면이 일정한 부재를 사용하였을 경우에 비하여 강재 사용량을 절감할 수 있다.Fourth, in the optimal design of the member cross-section according to the design stress, even if the position of the adjacent cheolgolbo is not in the same plane because the size or thickness of the member cross-section between the adjacent members are different. Therefore, the amount of steel used can be reduced as compared with the case of using a member having a constant cross section.

다섯째, 먼저 설치된 일측 철골보 일단에 철골보를 결합할 경우 수직 및 수평 방향 중심을 맞추기가 용이하여, 작업성 향상 및 안전성을 도모할 수 있다.
Fifth, when combining the cheolgolbo to one end of the first cheolgolbo installed first, it is easy to center the vertical and horizontal direction, it is possible to improve the workability and safety.
