중공형 콘크리트 충전 이중 강관기둥과 에이치형강 보의 접합부 구조 및 시공방법{Joint structure for hollow core concrete filled tube column and H shaped beam and construction method therefor}Joint structure for hollow core concrete filled tube column and H shaped beam and construction method therefor}

본 발명은 기둥과 보의 접합부 구조 및 시공방법에 관한 것으로, 보다 상세하게는 내부 강관과 외부 강관으로 이루어진 2중 강관의 내부 강관과 외부 강관 사이에 콘크리트를 충전한 중공형 콘크리트 충전 이중 강관기둥과 에이치형강 보의 접합부 구조 및 그 시공방법에 관한 것이다.The present invention relates to a joint structure of a column and a beam and a construction method, and more specifically, a hollow concrete-filled double steel pipe column filled with concrete between an inner steel pipe and an outer steel pipe of a double steel pipe composed of an inner steel pipe and an outer steel pipe; It relates to a joint structure of H-beams and a construction method thereof.

철골구조 건물은 기둥, 보, 가새 등의 개별부재를 연결하고 조립함으로써 이루어진다. 개개의 부재가 아무리 튼튼하게 설계되었더라도 이들의 연결이 취약하게 되어 있으면 건물 전체가 안전하다고 할 수 없을 것이다. 접합부는 연결되는 각 부재의 응력을 충분히 전달될 수 있도록 해야 한다. 접합부를 어떻게 설계하고 시공하느냐에 따라 구조안전은 물론 구조체 공사비에 미치는 영향도 크다.Steel structure buildings are made by connecting and assembling individual members such as columns, beams, and braces. No matter how sturdy the individual members are, if the connections are weak, the entire building will not be safe. The joints shall be capable of sufficiently transmitting the stress of each member to which they are connected. Depending on how the joints are designed and constructed, the impact on structural safety as well as the cost of the structure is greatly affected.

기둥과 보의 접합은 강접합과 핀접합으로 나눌 수 있으나 일반적으로 강접합으로 한다. 핀접합인 경우 고력볼트를 사용하고 강접합인 경우에는 용접으로 하는 것이 일반적이다. 용접접합의 경우 보 플랜지의 응력에 의해서 기둥의 플레이트가 면외 변형할 수 있는데 이것을 방지하기 위해 보가 접합되는 위치에 수평스티프너를 설치하여 보강해야 한다. 기둥 단면이 각형강관이나 원형강관일 때에는 보-기둥 접합부의 상세가 다소 복잡해지는데, 보강재(Diaphragm)의 형식에 따라 관통형 다이아프램 형식, 내부 다이아프램 형식 및 외부 다이아프램 형식이 있다. Column and beam joints can be divided into steel joints and pin joints, but generally steel joints. In the case of pin joints, high-strength bolts are used, and in the case of steel joints, welding is common. In the case of welded joint, the plate of column can be deformed out of plane due to the stress of beam flange. To prevent this, horizontal stiffener should be installed and reinforced at the position where beam is joined. When the column cross section is a square steel pipe or a round steel pipe, the details of the beam-column joint are somewhat complicated. There are a through diaphragm type, an internal diaphragm type, and an external diaphragm type depending on the type of diaphragm.

콘크리트 충전 강관구조는 강관과 콘크리트의 상호작용에 의해 뛰어난 구조 성능으로 초고층 구조시스템에 적합한 구조로 알려져 있다. 그러나 콘크리트 충전 강관기둥-H형강 보 접합에 대한 역학거동 규명과 시공의 어려움으로 여러 가지 접합형식에 대해서 연구중에 있다. 관통형 다이아프램 형식, 내부 다이아프램 형식은 고층건물에 적합한 것으로 알려져 일본에서 널리 사용되고 있으나, 우리나라는 상대적으로 지진 및 풍 하중이 작으므로 관통형 및 내다이아프램 접합형식을 그대로 적용시킬 경우 시공상에서 용접 및 콘크리트 충전성 등의 비효율적인 측면이 많다. 그리고 외부 다이아프램 형식의 제작·가공에 따른 비경제성 및 접합부 주변 외관의 복잡성 등이 단점으로 지적된다.Concrete filled steel pipe structure is known to be suitable for high-rise structural system with excellent structural performance by interaction between steel pipe and concrete. However, due to the difficulties in identifying and constructing the dynamic behavior of concrete-filled column-H-beam connections, various joint types are being studied. Through type diaphragm type and internal type diaphragm type are known to be suitable for high-rise buildings and are widely used in Japan.However, since Korea has relatively low earthquake and wind loads, the welding type can be used in construction when the through type and internal type diaphragm joint type is applied as it is. And inefficient aspects such as concrete fillability. In addition, it is pointed out the disadvantages such as inconsistency due to the manufacture and processing of the external diaphragm type and the complexity of the appearance around the joint.

도 1에서와 같이 본 발명에 따른 중공형 콘크리트 충전 이중 강관기둥과 에이치형강 보의 접합부 구조는, 내부 강관기둥(10), 내부 강관기둥(10)의 외주면에 접합된 4개의 H형 브라켓(20), H형 브라켓(20)을 서로 연결하면서 내부 강관기둥(10)을 둘러싸는 4개의 원호형 플레이트(Arc plate, 30), 원형 플레이트(30)가 연결되어 이루는 직경과 동일한 직경을 갖고 원호형 플레이트(30)의 상부와 하부에 각각 결합되는 2개의 링 플레이트(40), 각 링 플레이트(40)에 결합되고 내부 강관기둥(10)을 감싸는 외부 강관기둥(50), 내부 강관기둥(10)과 외부 강관기둥(50) 사이 그리고 내부 강관기둥(10)과 H형 브라켓(20) 및 원호형 플레이트(30) 사이에 충전되는 콘크리트(60) 및 각 H형 브라켓(20)에 접합되는 H형강 보(70)로 이루어진다. As shown in FIG. 1, the joint structure of the hollow concrete filled double steel pipe pillar and H-shaped steel beam according to the present invention includes four H-shaped brackets 20 joined to the outer circumferential surfaces of the inner steel pipe pillar 10 and the inner steel pipe pillar 10. ), The four arc-shaped plates (Arc plate, 30) surrounding the inner steel pipe column (10) while connecting the H-shaped bracket (20) and the circular plate (30) has the same diameter as the diameter formed by the circular arc type Two ring plates 40 respectively coupled to the upper and lower portions of the plate 30, outer steel pipe columns 50 and inner steel pipe columns 10 coupled to each ring plate 40 and surrounding the inner steel pipe columns 10. H-shaped steel joined to the concrete 60 and each H-shaped bracket 20 filled between the outer and outer steel pipe pillars 50 and between the inner steel pipe pillars 10 and the H-bracket 20 and the arc-shaped plate 30. Made of a beam 70.

내부 강관기둥(10)은 강관기둥-H형강 보로 이루어지는 철골골조의 주 기둥을 이루는 부재로서 외부 강관기둥(50)으로 둘러싸이고 콘크리트(60)로 피복된다. The inner steel pipe column 10 is a member that forms the main pillar of the steel frame frame made of steel pipe column-H-beams and is surrounded by an outer steel pipe column 50 and covered with concrete 60.

내부 강관기둥(10)에는 H형강 보(70)가 접합될 위치에 H형 브라켓(20)이 접합된다. 즉, H형 브라켓(20)은 H형강 보(70)를 접합하기 위해 내부 강관기둥(10)의 외주면에 용접으로 설치되는 것으로 접합되는 H형강 보(70)와 동일한 단면을 갖는다. 도 1에서는 내부 강관기둥(10)에 십자형으로 H형강 보(70)가 접합되는 경우, 즉 내부 강관기둥(10)이 중앙에 설치된 것을 예시한 것으로 H형 브라켓(20)은 4개가 설치되어 있다. 그러나 본 발명은 이에 한정되지 않으며 기둥(10)에 접합되는 보(70)의 수에 따라 외곽기둥의 경우 3개 또는 2개가 설치될 수 있다.The H-shaped bracket 20 is joined to the inner steel pipe column 10 at the position where the H-beam 70 is to be joined. That is, the H-shaped bracket 20 has the same cross section as the H-beams 70 joined by being welded to the outer circumferential surface of the inner steel pipe column 10 to join the H-beams 70. In FIG. 1, when the H-beam 70 is joined to the inner steel pipe column 10 in a cross shape, that is, the inner steel pipe column 10 is installed in the center, four H-shaped brackets 20 are installed. . However, the present invention is not limited thereto, and three or two outer pillars may be installed depending on the number of beams 70 joined to the pillars 10.

원호형 플레이트(30)는 브라켓(20)을 서로 연결하면서 내부 강관기둥(10)을 둘러싸도록 설치된다. 내부 강관기둥(10)을 둘러싸는 원호형 플레이트(30)의 직경은 링 플레이트(40) 및 외부 강관기둥(50)의 직경과 동일한 직경을 갖는다. 따라서 내부 강관기둥(10)과 외부 강관기둥(50) 사이에 콘크리트(60)를 충전할 때 내부 강관기둥(10), H형 브라켓(20) 및 원호형 플레이트(30)로 둘러싸인 공간 내부에도 콘크리트(60)가 채워지게 된다. 이를 위해 원호형 플레이트(30)의 양단부에는 H형 브 라켓(20)의 상부 플랜지와 하부 플랜지 사이로 삽입되고 웨브에 접하는 크기를 갖는 폐쇄단부(31)가 형성된다. 이 폐쇄단부(31)는 H형 브라켓(20)의 상부 플랜지와 하부 플랜지와 용접으로 접합되어 H형 브라켓(20)의 면외 변형을 방지하는 스티프너의 기능을 한다. The arc-shaped plate 30 is installed to surround the inner steel pipe pillar 10 while connecting the bracket 20 to each other. The diameter of the arc-shaped plate 30 surrounding the inner steel pipe column 10 has the same diameter as that of the ring plate 40 and the outer steel pipe column 50. Therefore, when the concrete 60 is filled between the inner steel pipe column 10 and the outer steel pipe column 50, the concrete inside the space surrounded by the inner steel pipe column 10, the H-type bracket 20 and the arc-shaped plate 30 60 will be filled. To this end, both ends of the arc-shaped plate 30 are formed between the upper flange and the lower flange of the H-shaped bracket 20 and a closed end 31 having a size in contact with the web is formed. The closed end 31 is joined to the upper flange and the lower flange of the H-type bracket 20 by welding to function as a stiffener to prevent out-of-plane deformation of the H-type bracket 20.

원호형 플레이트(30)와 동일 수직선 상에는 원호형 플레이트(30)가 연결되어 이루는 원의 직경과 동일한 직경을 갖는 링 플레이트(40)가 접합된다. 이 링 플레이트(40)는 외부 강관기둥(50)을 현장에서 간편 연결할 수 있도록 한다. On the same vertical line as the arc-shaped plate 30, the ring plate 40 having the same diameter as that of the circle formed by the arc-shaped plate 30 is connected is joined. The ring plate 40 allows the external steel pipe column 50 to be easily connected in the field.

외부 강관기둥(50)은 내부 강관기둥(10)을 감싸도록 설치된다. 외부 강관기둥(50)은 링 플레이트(40)와 동일한 직경을 갖고 링 플레이트(40)와 접합된다. H형 브라켓(20), 원호형 플레이트(30) 및 링 플레이트(40)는 공장에서 미리 내부 강관기둥(10)에 접합되는데 반해, 외부 강관기둥(50)은 내부 강관기둥(10)을 세우고 H형강 보(70)를 접합해 골조를 구축한 후 시공된다. 따라서 외부 강관기둥(50)은 적어도 2개로 분할되고 현장에서 용접으로 서로 연결되어 내부 강관기둥(10)을 감싸게 된다. 외부 강관기둥(50)은 콘크리트(60) 타설을 위한 거푸집 역할을 하게 되고 내부 강관기둥(10)과 함께 중공형 콘크리트 충전 이중 강관기둥을 구성한다. The outer steel pipe pillar 50 is installed to surround the inner steel pipe pillar 10. The outer steel pipe column 50 has the same diameter as the ring plate 40 and is joined to the ring plate 40. The H-bracket 20, the arc-shaped plate 30 and the ring plate 40 are joined to the inner steel pipe column 10 in advance at the factory, whereas the outer steel pipe column 50 sets up the inner steel pipe column 10 and It is constructed after joining the section beams 70 to build a frame. Therefore, the outer steel pipe pillar 50 is divided into at least two and connected to each other by welding in the field to surround the inner steel pipe pillar (10). The outer steel pipe column 50 serves as a formwork for placing concrete 60, and together with the inner steel pipe column 10 constitutes a hollow concrete filled double steel pipe column.

내부 강관기둥(10)과 외부 강관기둥(50) 사이에 그리고 내부 강관기둥(10)과 H형 브라켓(20) 및 원호형 플레이트(30)로 둘러싸인 공간에 콘크리트(60)가 충전된다. 따라서 도 3(a)에서와 같이 기둥과 보의 접합부가 콘크리트로 일체화된 구조로 되고 도 3(b)에서와 내부 강관기둥(10)은 콘크리트(60)에 의해 피복되어 화재시 내부 강관기둥(10)의 온도 상승을 억제할 수 있는 내화구조가 된다.Concrete 60 is filled between the inner steel pipe column 10 and the outer steel pipe column 50 and in a space surrounded by the inner steel pipe column 10 and the H-shaped bracket 20 and the arc-shaped plate 30. Therefore, as shown in FIG. 3 (a), the joint of the column and the beam is integrated with concrete, and in FIG. 3 (b) and the inner steel pipe column 10 is covered by the concrete 60 to prevent the internal steel pipe column ( It becomes a fireproof structure which can suppress the temperature rise of 10).

H형 브라켓(20)에는 H형강 보(70)가 접합된다. H형 브라켓(20)과 H형강 보(70) 간의 접합은 본 발명이 속하는 기술분에서 공지된 임의의 접합방법이 선택적으로 사용될 수 있다. The H-beam 70 is joined to the H-shaped bracket 20. Bonding between the H-shaped bracket 20 and the H-beams 70 can be optionally used any bonding method known in the art.

도 4a 내지 도 4d는 본 발명에 따른 중공형 콘크리트 충전 이중 강관기둥과 에이치형강 보의 접합부의 시공방법을 순서대로 나타낸 것이다. Figures 4a to 4d shows the construction method of the joint of the hollow concrete filled double steel pipe pillar and H-shaped steel beam in accordance with the present invention in order.

먼저, 내부 강관기둥(10)에 H형 브라켓(20), 원호형 플레이트(30) 및 링 플레이트(40)를 접합한다. 내부 강관기둥(10)이 1층 1절 형식인 경우 상부에만, 2층 1절 형식인 경우 H형강 보가 접합될 위치에 각각 H형 브라켓(20), 원호형 플레이트(30) 및 링 플레이트(40)를 접합한다. 도면에서는 1층 1절 방식의 경우를 도시하였다. H형 브라켓(20), 원호형 플레이트(30) 및 링 플레이트(40)를 내부 강관기둥(10)에 접합하는 작업은 현장에서 실시될 수도 있지만 공장에서 미리 수행되는 것이 바람직하다.First, the H-shaped bracket 20, the arc-shaped plate 30 and the ring plate 40 is bonded to the inner steel pipe column (10). H-bracket 20, arc-shaped plate 30, and ring plate 40 at the position where the H-beams are to be joined, respectively, when the inner steel pipe column 10 is the first-tier one-section type, and the two-layer one-section type. ). In the figure, the case of the one-layer one-section system is shown. Bonding the H-shaped bracket 20, the arc-shaped plate 30 and the ring plate 40 to the inner steel pipe column 10 may be carried out in the field, but is preferably performed in advance in the factory.

다음으로, 도 4a에서와 같이 H형 브라켓(20), 원호형 플레이트(30) 및 링 플레이트(40)가 접합된 내부 강관기둥(10)을 평면 계획에 따라 설치한다.Next, as shown in FIG. 4a, the inner steel pipe column 10 to which the H-shaped bracket 20, the arc-shaped plate 30, and the ring plate 40 are joined is installed according to a plan.

다음으로, 도 4b에서와 같이 내부 강관기둥(10)에 H형강 보(70)를 접합하여 골조를 완성한다.Next, the H-beam beam 70 is bonded to the inner steel pipe column 10 as shown in Figure 4b to complete the frame.

다음으로, 도 4c에서와 같이 외부 강관기둥(50)을 내부 강관기둥(10)을 감싸도록 설치한다. 외부 강관기둥(50)은 내부 강관기둥(10)에 접합된 링 플레이트(40)에 연결된다. 이때, 외부 강관기둥(50)과 내부 강관기둥(10) 사이에 수직철근을 추가로 배근할 수 있다. Next, as shown in FIG. 4c, the outer steel pipe pillar 50 is installed to surround the inner steel pipe pillar 10. The outer steel pipe column 50 is connected to the ring plate 40 bonded to the inner steel pipe column 10. At this time, a vertical reinforcing bar may be additionally disposed between the outer steel pipe column 50 and the inner steel pipe column 10.

마지막으로, 도 4d에서와 같이 내부 강관기둥(10)과 외부 강관기둥(50) 사이의 공간에 콘크리트(60)를 충전한다. 이때, 내부 강관기둥(10)과 H형 브라켓(20) 그리고 원호형 플레이트(30)로 둘러싸인 공간에도 콘크리트(60)가 밀실하게 충전된다. Finally, the concrete 60 is filled in the space between the inner steel pipe pillar 10 and the outer steel pipe pillar 50 as shown in FIG. 4D. At this time, the concrete 60 is tightly filled even in the space surrounded by the inner steel pipe column 10, the H-bracket 20 and the arc-shaped plate 30.

이상과 같이 본 발명에 따르면 내부 강관기둥(10)과 H형강 보(70)로 구성되는 골조를 먼저 시공하여 시공중 하중은 내부 강관기둥(10)이 받도록 하면서 급속하게 골조공사를 진행할 수 있을 뿐만 아니라 기둥-보 접합부가 철골콘크리트 구조가 됨으로서 접합부의 일체성이 높아져 접합부의 성능이 향상된다. 그리고 내부 강관기둥(10)에 미리 링 플레이트(40)가 접합되어 있으므로 내부 강관기둥(10)을 피복하는 콘크리트를 타설하기 위한 거푸집으로 기능하는 외부 강관기둥(50)을 간편하게 현장에서 결합시킬 수 있다. 이렇게 내부 강관기둥이 콘크리트로 피복됨으로써 화재시 내부 강관기둥의 온도 상승을 억제할 수 있는 내화구조를 구현할 수 있으며, 기둥이 내부 강관기둥, 콘크리트 및 외부 강관기둥으로 구성됨으로써 기둥의 내력 및 좌굴성능을 크게 향상시킬 수 있다. 즉, 본 발명에 따르면 기둥에 별도의 내화피복이 불필요하며 기둥-보 접합부의 일체성이 확보되어 접합부의 성능이 향상된다. As described above, according to the present invention, the first construction of the frame consisting of the inner steel pipe column 10 and the H-beam steel 70 can be carried out rapidly during the construction while the load is received by the inner steel pipe column (10). Rather, the column-beam joint becomes a steel concrete structure, thereby increasing the integrity of the joint, thereby improving the performance of the joint. And since the ring plate 40 is bonded to the inner steel pipe column 10 in advance, the outer steel pipe column 50 serving as a formwork for pouring concrete covering the inner steel pipe column 10 can be easily combined in the field. . As the inner steel pipe pillar is covered with concrete, it is possible to realize a fireproof structure that can suppress the temperature rise of the inner steel pipe pillar in case of fire, and the pillar is composed of the inner steel pipe pillar, concrete and the outer steel pipe pillar, thereby improving the strength and buckling performance of the pillar. It can greatly improve. That is, according to the present invention, there is no need for a separate fireproof coating on the column, and the integrity of the column-beam joint is secured, thereby improving the performance of the joint.
