콘크리트 충전 원형강관기둥과 보의 연결장치{Concrete Filled Steer Tube and beams connecting device}Concrete Filled Steer Tube and beams connecting device

본 발명은 콘크리트 충전 원형강관기둥(CFT; Concrete Filled Steer Tube)과 보의 연결장치에 관한 것으로서, 더욱 상세하게는 고리(Ring) 형태의 다이아프램을 원형강관기둥의 보 설치 위치마다 공장에서 자동용접하여 상기 다이아프램의 외경이 상기 원형강관기둥의 외주면과 근접되도록 하되 H형강 보의 상,하부플랜지가 볼트체결 가능하도록 상기 다이아프램에 원주방향으로 볼트관통공을 형성함으로써, 다이아프램이 원형강관기둥에서 많이 돌출되지 않으므로 차량운반시 부피를 많이 차지하지 않아 물류비를 절감할 수 있는 콘트리트충전 원형강관기둥과 보의 연결장치에 관한 것이다.The present invention relates to a device for connecting a concrete filled steer tube (CFT) and a beam, and more specifically, a ring-shaped diaphragm is automatically welded at a factory for each beam installation position of a circular steel pipe column. By making the outer diameter of the diaphragm close to the outer circumferential surface of the circular steel pipe pillar, by forming a bolt through hole in the circumferential direction of the diaphragm so that the upper and lower flanges of the H-beam can be bolted, the diaphragm is a circular steel pipe pillar Since it does not protrude much from the vehicle, it does not occupy a lot of volume during transportation, and it relates to a connection device of the concrete-filled circular steel tube column and beam that can reduce the logistics cost.

콘크리트 충전 강관기둥(CFT; Concrete Filled Steer Tube)은 기존의 강관 기둥에 콘크리트를 충전한 것으로서, 뛰어난 내진성능과 우수한 내화성능이 입증되어 기존의 RC조(철근 콘크리트), S조(철골), SRC조(철골 콘크리트 합성)에 이은 제 4의 구조로서 최근 각광을 받고 있다. 콘크리트의 충전성이 중요하므로 고유동 콘크리트가 사용되고 있으며, 기둥 내부에 공극 없이 충전될 필요가 있다. 대개 콘크리크 버켓을 이용한 트레미관 충전법과 펌프 배관을 이용한 하부 압입법으로 시공한다.Concrete Filled Steer Tube (CFT) is a concrete filled steel tube column, which has been proven to have excellent seismic resistance and excellent fire resistance, so that existing RC (reinforced concrete), S (steel), SRC As a fourth structure following the tank (steel concrete composite), it has been in the spotlight recently. Since the filling property of concrete is important, high-flow concrete is used, and it needs to be filled without voids in the column. It is usually constructed by filling the trem tube using concrete buckets and bottom press using pump pipes.

콘크리트 충전 강관 기둥은 대부분 각형 강관이 주로 시공되어 왔다. 원형강관 기둥은 콘크리트의 우수한 압축력을 최대한 살릴 수 있는 매우 우수한 공법임이 이미 실험으로 수차례 검증되었음에도 불구하고, 제작 과정에 곡면 가공이 많으므로 작업 인력의 소모가 많아 제작비용이 상승하는 문제점이 있었고, 외부 다이아프램에 브라켓이 돌출 연결된 형태의 부재를 사용하므로 공장에서 취부작업시 다루기 힘들고 용접량이 많으며 부피가 커서 많이 운반할 수 없는 문제점도 있었다. 그리하여 각형 강관이 주로 콘크리트 충전 강관기둥으로 채택되어 왔다. 그러나 각형 강관은 콘크리트의 압축력을 최대한으로 이용하지 못하고 강관의 내부를 채워주는 보조적인 역할만을 해왔다.Concrete-filled steel pipe columns have been mainly constructed of square steel pipes. Although the circular steel pipe column has been proved several times by experiments that it is a very good method that can maximize the excellent compressive force of concrete, there is a problem that the manufacturing cost increases due to the large number of curved work in the production process, Brackets protrudingly connected to the external diaphragm, so it was difficult to handle during the installation work in the factory, and there was a problem in that a large amount of welding and a large volume could not be transported. Thus, square steel pipes have been mainly adopted as concrete filled steel pipe columns. However, square steel pipes have only played a supporting role in filling the inside of the steel pipes without making the best use of the compressive force of concrete.

국내실용등록 제358912호는 원형강관기둥에 다이아프램을 용접한 기술이 개시된 바 있다. 이는 다이아프램이 원형강관기둥에서 많이 돌출되지 않으므로 차량 운반시 많이 실을 수 있어 물류비 절감 차원에서 이점이 있다. 그러나 건설현장에서 상기 다이아프램에 보를 직접 용접하는 방식이므로 고층으로 올라가는 보와 원형강관기둥의 용접에 어려움이 있으며, 용접에 따른 강관기둥과 보의 열변형으로 인하여 수직 및 수평도를 맞추기 어려운 등의 단점이 있었다.Korean Utility Registration No. 358912 has disclosed a technique in which a diaphragm is welded to a round steel tube column. This is because the diaphragm does not protrude much from the round steel pipe column, so it can be loaded a lot when transporting the vehicle. However, since the beam is directly welded to the diaphragm at the construction site, it is difficult to weld the beam and the round steel pipe pillar that rise to a higher floor, and it is difficult to adjust the vertical and horizontal degrees due to the heat deformation of the steel pipe pillar and the beam caused by the welding. There was a downside.

국내실용등록 제394341호 및 일본 특개평 제14-161581호에는 원형강관기둥에 다이아프램을 용접한 상태에서 공장에서 출하되면 건설현장에서 보의 상,하부플랜지와 연결판으로 볼트체결하는 기술이 개시된 바 있다.Korean Utility Registration No. 394341 and Japanese Laid-Open Patent Publication No. 14-161581 disclose the technique of bolting to the beam upper and lower flanges and connecting plate at the construction site when it is shipped from the factory with the diaphragm welded to the round steel pipe column. There is a bar.

그러나 이들 기술들은 다이아프램에 보를 볼트체결하기 위하여 볼트관통공이 형성된 브래킷이 다이아프램에서 많이 돌출되어 있으므로 부피를 많이 차지하여 물류비가 증가되는 단점이 있었다.However, these technologies have a disadvantage in that the logistics cost is increased by taking up a lot of volume since the bracket through which the bolt through-hole is formed to bolt the diaphragm to the beam is protruded from the diaphragm.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 제철공장에서 양산된 원자재를 이용하여 용접량을 최소화시켜서 제작비용을 낮추고 상부에서 콘크리트믹서 펌프로 직접 타설하는 방식으로 콘크리트 충전 작업이 원활하도록 하여 지진과 화재에 강한 CFT(Concrete Filled Steel Tube)공법을 널리 보급함에 있다. 본 발명의 다른 목적은 제철공장에서 양산된 원형강관기둥에 철판의 두께만 다른 똑같은 규격으로 생산된 고리 형태의 다이아프램을 용접하기 위하여 로울러 위에 올려 저속 회전시키면서 서브머지드 용접기나 기타 자동용접기로 용접함으로써, 용접 품질이 우수하고 대량생산으로 인한 생산성 향상에도 크게 기여할 수 있는 원형강관기둥을 생산하고자 한다.The present invention was developed in view of the conventional problems, the object of the present invention is to reduce the production cost by minimizing the welding amount by using the raw materials produced in the steel mill in the concrete filling operation in the way of pouring directly into the concrete mixer pump from the top It is to spread the CFT (Concrete Filled Steel Tube) method that is resistant to earthquakes and fires by making it smooth. It is another object of the present invention to weld circular diaphragm produced in the same standard with different steel plate thickness to the round steel pipe column produced in the steel mill, while welding on a roller while rotating at a low speed while using a submerged welding machine or other automatic welding machine. By doing so, it is intended to produce a circular steel pipe column which can contribute to the improvement of productivity due to the excellent welding quality and mass production.

강관 바깥면에 다이아프램이 용접되면 상하부 다이아프램 사이에 H형강 보의 웨브(Web)와 접합되는 가셋트를 용접하여 고정시키고 상기 다이아프램에는 원주방향으로 볼트체결공을 천공하여 보의 플랜지와 연결판으로 볼트체결할 수 있도록 해준다. 상기 원호형의 볼트체결공으로 인하여 보와 다이아프램이 견고하게 조립되므로 원형강관기둥을 공장에서 생산하여 건설현장으로 운반시키는 과정에서 상기 다이아프램의 부피 감소로 물류비를 절감할 수 있는 콘크리트타설 원형강관기둥과 ㅂ보의 연결장치를 제공함에 있다.When the diaphragm is welded to the outer surface of the steel pipe, the gaskets which are joined to the web of the H-beams are fixed between the upper and lower diaphragms, and the bolt diaphragm is drilled in the circumferential direction to connect the flange of the beam. Allows bolting to the plate. Since the beam and diaphragm are firmly assembled due to the arc-shaped bolting hole, the concrete casting circular steel pipe column can reduce the logistics cost by reducing the volume of the diaphragm in the process of producing the circular steel pipe column at the factory and transporting it to the construction site. It is to provide a connection device of the and the bogie.

본 발명은 고리 형태의 다이아프램을 브라켓이 없는 원형 다이아프램으로 제작하게 되면 종래 직사각판재 형태의 연결판(Sprice Plate)을 볼트로 조립하기 어렵게 된다. 이를 해소하고자 상기 다이아프램에 원주방향으로 볼트체결공을 천공하고 연결판에도 같은 형태로 원주방향으로 볼트체결공을 천공하면 보와 다이아프램의 볼트체결이 가능해진다.According to the present invention, when the ring-shaped diaphragm is manufactured as a circular diaphragm without a bracket, it is difficult to assemble a conventional plate-shaped connecting plate (Sprice Plate) with a bolt. In order to solve this problem, if the bolt fastening hole is drilled in the circumferential direction on the diaphragm, and the bolt fastening hole is drilled in the circumferential direction in the same form in the connecting plate, the bolt fastening of the beam and the diaphragm becomes possible.

다이아프램의 원형 외주면과 H형강 보의 직선형 플랜지 끝단면의 접합에 있어서는 상기 다이아프램에 접선방향으로 직선형 면접부를 형성하여 보의 끝단면이 맞닿아 접합 되게 한다. 따라서 보와 다이아프램을 연결판으로 볼트체결할때 공간이 형성되지 않아 마찰 접촉성 및 조립의 정밀성이 향상된다.In the joining of the circular outer circumferential surface of the diaphragm and the straight flange end surface of the H-beams, a linear contact portion is formed on the diaphragm in a tangential direction so that the end surface of the beam abuts. Therefore, no space is formed when bolting the beam and the diaphragm to the connecting plate, thereby improving friction contact and assembly precision.

이를 위하여 본 발명은 원형강관기둥의 보 연결부위마다 상,하부다이어프램을 용접하여 원형강관기둥과 보를 연결판으로 볼트체결 하기위한 원형강관기둥과 보의 연결장치에 있어서, 상기 상,하부다이어프램은 원주방향을 따라 다수개의 볼트체결공이 각각 형성되고, 상기 연결판에는 상기 상,하부다이어프램에 형성된 볼트체결공과 대응되도록 원주방향을 따라 다수개의 볼트체결공이 형성되어 상기 상,하부다이어프램과 연결판이 원주방향을 따라 볼트체결되는 특징이 있다.To this end, the present invention in the connecting device of the circular steel pipe column and beam for bolting the circular steel pipe column and the beam to the connecting plate by welding the upper and lower diaphragm for each beam connection portion of the circular steel pipe column, the upper, lower diaphragm is the circumference A plurality of bolt fastening holes are formed along the direction, and the connecting plate has a plurality of bolt fastening holes formed along the circumferential direction so as to correspond to the bolt fastening holes formed in the upper and lower diaphragms, so that the upper and lower diaphragms and the connecting plate are arranged in the circumferential direction. There is a feature that is bolted together.

본 발명은 철강공장에서 양산된 강관을 사용하여 2차 제작함으로 강관제작의 번거로움과 용접작업을 최소화시키고, 자동생산을 할 수 있는 기틀을 다짐으로서 생산성 향상과 비용 감소에 큰 역할을 할 것으로 기대한다. 현장에서의 용접과 절단 작업을 최소화하여 현장의 안전은 물론이고 지진과 화재에 효율적인 CFT(Concrete Filled Steer Tube)공법을 널리 보급함에 있다. 특히, 원형강관기둥의 다이아프램의 원방향 비율에 따라 볼트관통구멍을 가공하여 보를 연결하므로 연결판(Sprice Plate)이 횡으로 넓은 면적이 기둥에 직접 연결되므로 보의 횡 하중에 따른 지진에 특히 효과적이다.The present invention is expected to play a major role in improving productivity and reducing costs by minimizing the hassle and welding work of steel pipe production and making a foundation for automatic production by making secondary production using steel pipes produced in steel mills. do. By minimizing welding and cutting work in the field, it is widely spreading the CFT (Concrete Filled Steer Tube) method that is effective in the field as well as earthquake and fire. Particularly effective for earthquakes due to transverse loads of beams, since the wide plate is directly connected to the column by processing bolt through holes according to the circular ratio of the diaphragm of circular steel pipes. to be.

원형강관기둥 내부에 장해물이 없어서 상부에서 콘크리트 믹서 펌프로 직접 타설하므로 고유동콘크리트(High Flowable Concret)가 아니어도 일반 고강도 콘크리트를 공극 없이 쉽게 타설할 수 있다. 요즘은 건물 상층부에 타워크레인과 별도로 콘크리트믹서 펌프 헤드가 타워크레인처럼 위로 올라가면서 콘크리트를 타설한다. 따라서 콘크리트 버켓이 필요없는 것이다. 원형강관기둥 최상부 다이아프램은 또 다른 상부측의 원형강관기둥의 하부 베이스와 조립된다.Since there is no obstacle inside the round steel pipe column, it is poured directly into the concrete mixer pump from the top, so it is easy to place general high-strength concrete without voids even if it is not high flow concrete. Nowadays, the concrete mixer pump head is placed on the upper floor of the building and poured concrete as the tower crane rises up. So you don't need a concrete bucket. The top diaphragm of the round steel pipe column is assembled with the lower base of the round steel pipe column on the other side.

하부측의 원형강관기둥의 최상부 다이아프램과 상부측의 원형강관기둥의 베이스 플레이트(Base Plate)를 볼트로 연결하므로 설치가 편리하고 정밀도가 우수하다. 이때 하부기둥 상부강관 내측에 다수개의 철근을 용접 부착하여 상부기둥 베이스 내부에 매설하여 기둥의 연속성과 지진으로부터 기둥을 보강한다.The upper diaphragm of the round steel pipe column on the lower side and the base plate of the round steel pipe column on the upper side are bolted, so installation is convenient and precision is excellent. At this time, a plurality of reinforcing bars are welded inside the upper column of the lower column and embedded in the upper column base to reinforce the column from the continuity of the column and the earthquake.

본 발명은 다이아프램이 원형강관기둥의 외주면에 근접되므로 돌출 부피를 많이 차지하지 않아 차량운반시 원형강관기둥을 보다 많이 운반할 수 있어서 물류비가 획기적으로 절감되는 이점이 있다. 종래에는 다이아프램과 보의 플랜지를 연결하기 위하여 다이아프램에 브래킷을 돌출시켜 보의 플랜지와 연결판으로 볼트체결해야 했으므로 부피를 많이 차지하여 물류비가 증가되었다.Since the diaphragm is close to the outer circumferential surface of the round steel pipe column, the diaphragm does not occupy a large amount of protruding volume, and thus, the transport cost of the round steel pipe column can be more greatly reduced when the vehicle is transported. In the related art, in order to connect the diaphragm and the flange of the beam, the bracket had to be protruded to the diaphragm and bolted to the flange and the connecting plate of the beam.

본 발명은 다이아프램이 원형강관기둥과 근접되므로 부피를 많이 차지하지 않는데, 이는 다이아프램과 보의 플랜지를 연결하는 연결판을 볼트체결하기 위하여 볼트관통공이 상기 다이아프램에 원주방향으로 천공되므로 가능한 것이다. 또한 상기 연결판이 다이아프램의 원주방향을 따라 횡으로 폭이 증가되어 볼트체결면적이 횡으로 넓게 분포되므로 횡방향 비틀림하중에 대한 응력이 증가되어 좌우측의 흔들림에 따른 내진성이 향상되는 이점이 있다.In the present invention, the diaphragm is close to the round steel tube pillar, so that it does not take much volume. This is possible because the bolt through hole is circumferentially drilled on the diaphragm to bolt the connecting plate connecting the flange of the diaphragm and the beam. . In addition, since the connecting plate is increased in width along the circumferential direction of the diaphragm, the bolt fastening area is widely distributed in the horizontal direction, so that the stress against the lateral torsional load is increased, so that the seismic resistance due to the shaking on the left and right sides is improved.

본 발명 한 실시예는 원형강관기둥(10)의 보(50) 설치위치마다 다이어프램이 용접된다. 상기 다이어프램은 보(50)의 상부플랜지(52) 및 하부플랜지(53)와 대응되도록 상부다이어프램(20) 및 하부다이어프램(30)의 한쌍으로 구성되는데, 내부에 상기 원형강관기둥(10)이 관통되는 관통부(21)(31)가 형성되고 외주면은 원형으로 구성된다. 상기 각 다이어프램(20)(30)에는 보(50)의 플랜지 끝단이 면접되도록 원의 접선방향으로 직선형태의 면접부(23)(33)가 각각 형성되어 보의 끝단과 다이어프램의 외주면이 빈틈없이 면접되도록 해준다.In one embodiment of the present invention, the diaphragm is welded at each installation position of the beam 50 of the circular steel pipe column 10. The diaphragm is composed of a pair of upper diaphragm 20 and lower diaphragm 30 to correspond to the upper flange 52 and the lower flange 53 of the beam 50, the circular steel tube pillar 10 therein Through portions 21 and 31 are formed and the outer circumferential surface is formed in a circular shape. Each of the diaphragms 20, 30 is formed with a linear interview portion 23, 33 in the tangential direction of the circle so that the flange end of the beam 50 is interviewed, so that the end of the beam and the outer peripheral surface of the diaphragm are Allow interviews.

상기 상부다이어프램(20) 및 하부다이어프램(30)은 연결판(60)에 의해 보(50)의 상,하부플랜지(52)(53)와 볼트체결되는데, 이를 위하여 상기 다이어프램(20)(30)들에는 원주방향을 따라 다수개의 볼트체결공(22)(32)이 천공되고 상기 연결판(60)에도 상기 원주방향을 따라 다수개의 볼트체결공(63)이 천공된다. 상기 연결판(60)은 볼트체결공(62)이 원주방향으로 형성되어 횡방향으로 폭이 증가되는 효과가 있으므로 보와 강관기둥의 횡방향 내진이 보강되는 이점이 있다.The upper diaphragm 20 and the lower diaphragm 30 are bolted to the upper and lower flanges 52 and 53 of the beam 50 by the connecting plate 60, for this purpose the diaphragm 20, 30 In the field, a plurality of bolting holes 22 and 32 are drilled in the circumferential direction, and a plurality of bolting holes 63 are drilled in the connecting plate 60 in the circumferential direction. The connecting plate 60 has the advantage that the bolt fastening hole 62 is formed in the circumferential direction so that the width is increased in the transverse direction so that the lateral seismic resistance of the beam and the steel pipe pillar is reinforced.

또한 상기 연결판(60)에는 보(50)의 체결위치에 플랜지의 길이방향을 따라 직선형태로 배열된 다수개의 볼트체결공(63)이 형성되어 다이어프램과 보를 볼트로 연결시킨다.In addition, the connecting plate 60 is formed with a plurality of bolt fastening holes 63 arranged in a straight line along the longitudinal direction of the flange at the fastening position of the beam 50 to connect the diaphragm and the beam by bolts.

상기 상,하부다이어프램(20)(30)의 사이에는 보(50)의 측면 웨브(51)와 대응되도록 가셋트(40)가 용접되며 이들 가셋트(40)와 웨브(51)는 현장에서 웨브연결판(61)으로 볼트체결된다.Between the upper and lower diaphragms 20 and 30, the gastets 40 are welded to correspond to the side webs 51 of the beams 50, and these gussets 40 and the webs 51 are webs in the field.
