도 2 내지 도 4는 본 발명에 따른 철근접합형 조립식 철골튜브의 다양한 실시예를 도시한다. 도시하고 있는 바와 같이 본 발명은 철판을 절곡 성형한 단위부재(110) 복수개를 조립하여 완성한 조립식 철골튜브(100) 내부에 내부철근(200)을 접합 설치한다는데 특징이 있다. 2 to 4 show various embodiments of the reinforcement-type prefabricated steel tube according to the present invention. As shown, the present invention is characterized in that the inner reinforcement 200 is bonded to the inside of the prefabricated steel tube 100 completed by assembling a plurality of unit members 110 formed by bending the steel plate.

조립식 철골튜브(100)는 특허 제0684931호에 따른 것으로, 도 1과 같이 내부가 빈 폐쇄형의 원형 또는 각형 튜브 형상의 단면을 갖는 철골부재로 완성된다. 다시 말해, 조립식 철골튜브(100)는 튜브의 단면 일부와 일치하는 형상을 갖는 면형성부(111)와 상기 면형성부(111)의 양단부에서 튜브의 내부를 향해 절곡된 절곡부(112)를 포함하도록 철판을 절곡 성형하여 형성시킨 단위부재(110)를 복수개 준비하고, 상기 단위부재(110) 상호 간을 절곡부(112)가 서로 맞닿도록 배치한 후 접합함으로써 완성하는 것이다. 단위부재(110)를 준비함에 있어 면형성부(111)와 절곡부(112)는 서로 수직이 되게 절곡하는 것(도 1 참조)은 물론, 서로 예각을 이루게 절곡하는 것(도 2 내지 도 4 참조)도 가능하다. 어떻게 절곡하든지 간에 단위부재(110)에서 면형성부(111)와 절곡부(112)가 만나는 절곡모서리는 철판의 절곡성형 과정에서 자연스럽게 라운드형으로 처리되기 마련이므로, 상기 단위부재(110) 상호간을 절곡부(112)가 서로 맞닿도록 배치하면 절곡모서리가 만나는 부분은 면형성부(111)보다 들어간 형태의 함몰부(120)로 형성되며, 이러한 함몰부(120)는 단위부재(110) 상호 간을 접합할 때 용접살을 채우면서 용접접합하기 위한 공간으로 활용할 수 있다. Prefabricated steel tube 100 is in accordance with the patent 0684931, as shown in Figure 1 is completed with a steel member having a closed circular or rectangular tube-shaped cross-section inside.

In preparing the unit member 110, the surface forming portion 111 and the bent portion 112 are bent perpendicularly to each other (see FIG. 1), as well as bent at an acute angle to each other (FIGS. 2 to 4). Is also possible. Regardless of how it is bent, the bending corner where the surface forming portion 111 and the bending portion 112 meet in the unit member 110 is naturally processed to be round in the bending forming process of the iron plate, so that the unit members 110 are mutually When the bent part 112 is disposed to be in contact with each other, a portion where the bent edge meets is formed as a recessed part 120 having a shape more than that of the surface forming part 111, and the recessed part 120 is formed between the unit members 110. It can be used as a space for welding while filling the welding joint.

도 2 내지 도 4에서는 두 가지 종류의 단위부재(C형 단위부재와 리브L형 단위브재)를 이용하여 두 가지 형태의 조립식 철골튜브(100)를 완성한 형태를 구체적인 실시예로 제안하나, 본 발명에서도 도 1과 같이 다양한 종류의 단위부재(110)를 사용하여 다양한 형태의 조립식 철골튜브(100)를 완성할 수 있음은 물론 외주면에 섬유강화플라스틱 등에 의한 보강재로 보강할 수도 있다.In Figures 2 to 4 proposes a form of completing two types of prefabricated steel tube 100 by using two types of unit members (C type unit member and rib L type unit material) as a specific embodiment, but the present invention In FIG. 1, various types of prefabricated steel tubes 100 may be completed using various types of unit members 110 as well as reinforcement materials such as fiber reinforced plastics on the outer circumferential surface thereof.

본 발명은 상기와 같은 조립식 철골튜브(100)를 기본으로, 조립식 철골튜브(100) 내부에 조립식 철골튜브(100)에 구속되게 내부철근(200)을 설치할 것을 제안한다. 내부철근(200)은 도 2와 도 3에서와 같이 조립식 철골튜브(100) 내표면에 직접 접합하는 방식으로 설치하거나, 도 4에서와 같이 조립식 철골튜브(100) 내표면에 철근고정구(300)를 접합 설치한 후 철근고정구(300)에 구속시키는 방식으로 설치할 수 있다. 다만 내부철근(200)은 조립식 철골튜브(100) 내표면에 직접 접하거나 근접할수록 모멘트 내력을 최대화하는데 유리하므로 도 4와 같이 철근고정구(300)를 이용하여 설치하는 경우에는 내부철근(200)이 조립식 철골튜브(100) 내표면에 최대한 근접하게 설치하도록 한다. 물론 내부철근(200)은 요구내력에 따라 필요 위치에 자유롭게 설치할 수 있다.The present invention proposes to install the internal reinforcement 200 to be restrained by the prefabricated steel tube 100 inside the prefabricated steel tube 100 based on the prefabricated steel tube 100 as described above. The internal reinforcement 200 is installed in a manner of directly bonding to the inner surface of the prefabricated steel tube 100, as shown in Figures 2 and 3, or the reinforcing fixture 300 on the inner surface of the prefabricated steel tube 100 as shown in FIG. After installing the joint can be installed in a manner to restrain the rebar fixture 300. However, since the internal reinforcement 200 is in direct contact with or close to the inner surface of the prefabricated steel tube 100, the moment strength is advantageous to maximize the internal reinforcement 200 when installed using the reinforcing bar 300 as shown in FIG. Prefabricated steel tube 100 to be installed as close as possible to the inner surface. Of course, the internal reinforcement 200 can be freely installed in the required position according to the required strength.

도 4에서는 철근고정구(300)로 철선을 절곡하여 철근안착부(311)을 형성시킨 절곡철선(310)을 제안하며, 내부철근(200)은 철근고정구(300)의 철근안착부(311)에 안착시킴으로써 철근고정구(300)에 구속 설치할 수 있다. 절곡철선(310)은 하나의 철근안착부(311)는 물론 여러 개의 철근안착부(311)가 동시에 형성되도록 구성할 수 있다. In FIG. 4, the bending steel wire 310 is formed by bending the steel wire into the reinforcing bar 300 to form the reinforcing seat 311, and the inner reinforcing bar 200 is connected to the reinforcing seat 311 of the reinforcing bar 300. It can be restrained and installed in the reinforcing bar 300 by being seated. The bending wire 310 may be configured such that not only one rebar seating portion 311 but also several rebar seating portions 311 are simultaneously formed.

상기와 같이 내부철근(200)이 마련된 조립식 철골튜브(100)는 결국 도 1과 같은 조립식 철골튜브(100)가 내부철근(200)에 의해 보강된 형태가 된다. 조립식 철골튜브(100)는 그 자체가 단면 형태상 약축이 없기 때문에 압축재로서 좌굴 내력 확보에 유리한 형태인데, 이러한 조립식 철골튜브(100) 내부에 내부철근(200)을 구속시키면 좌굴 내력을 더욱 보강할 수 있다. 나아가 내부철근(200)을 철골튜브(100) 내표면에 최대한 근접하게 구속시키면 모멘트 내력을 최대화할 수 있다. 이와 같이 내부철근(200)에 의해 보강되기 때문에, 조립식 철골튜브(100)는 상당히 얇은 두께의 철판을 이용하여 단위부재(110)를 준비할 수 있다. The prefabricated steel tube 100 provided with the internal reinforcement 200 as described above becomes a form in which the prefabricated steel tube 100 as shown in FIG. 1 is reinforced by the internal reinforcement 200. Prefabricated steel tube 100 is a form that is advantageous to secure buckling strength as a compression material because there is no weak axis in cross-sectional shape, by restraining the internal reinforcement 200 in the prefabricated steel tube 100 to further strengthen the buckling strength can do. Furthermore, restraining the inner rebar 200 as close as possible to the inner surface of the steel tube 100 may maximize the moment strength. Since it is reinforced by the internal reinforcement 200 as described above, the prefabricated steel tube 100 can prepare the unit member 110 using a steel plate of a fairly thin thickness.

이상과 같은 본 발명에 따른 철근접합형 조립식 철골튜브는 내부에 콘크리트를 충전함으로써 CFT구조용 강관부재로 사용할 수 있다. 내부에 콘크리트가 충전되는 경우에는 조립식 철골튜브(100)와 내부철근(200)은 콘크리트에 구속되어 구조적인 내력을 발휘하며, 특히 조립식 철골튜브(100)에서 절곡부(112)는 콘크리트에 묻혀 앵커역할을 하게 되므로 압축력 작용시에는 콘크리트의 구속효과를 증대시키고 전단력 작용시에는 내부의 콘크리트에까지 응력을 전달하는데 기여한다.Reinforced bonded prefabricated steel tube according to the present invention as described above can be used as a steel pipe member for the CFT structure by filling concrete therein. When the concrete is filled in the prefabricated steel tube 100 and the internal reinforcement 200 is constrained to concrete to exhibit structural strength, in particular, the bent portion 112 in the prefabricated steel tube 100 buried in the concrete anchor As it acts, it increases the restraint effect of concrete under the action of compressive force and contributes to the transfer of stress to the concrete within the shear force.

본 발명에 따른 철근접합형 조립식 철골튜브는, 조립식 철골튜브(100)를 완성하기 전에 단위부재(110)에 내부철근(200)을 접합하거나 철근고정구(300)를 접합함으로써 제작할 수 있다. 다시 말해, 조립식 철골튜브(100)를 구성하는 단위부재(110)를 서로 접합하지 않아 폐쇄되지 않은 상태로 조립식 철골튜브(100)를 준비하고, 폐쇄되지 않은 상태의 조립식 철골튜브(100)에서 단위부재(110) 내표면에 내부철근(200)을 직접 접합하여 설치하거나 또는 단위부재(110) 내표면에 철근고정구(300)를 접합한 후 내부철근(200)을 철근고정구(300)에 구속시켜 설치하고, 단위부재(110) 상호 간을 절곡부(112)가 서로 맞닿도록 배치한 상태에서 용접 접합하여 조립식 철골튜브(100)를 폐쇄시키는 것이다.Reinforcing-type prefabricated steel tube according to the present invention, before completing the prefabricated steel tube 100 can be manufactured by bonding the internal reinforcement 200 to the unit member 110 or the reinforcing fixture 300. In other words, the unit member 110 constituting the prefabricated steel tube 100 is not bonded to each other to prepare a prefabricated steel tube 100 in a non-closed state, the unit in the prefabricated steel tube 100 in a non-closed state Install the internal reinforcing bars 200 directly on the inner surface of the member 110 or bond the reinforcing bar 300 to the inner surface of the unit member 110, and then restrain the inner reinforcing bars 200 to the reinforcing bar 300. It is installed, and welded in the state in which the bent portion 112 is arranged to abut each other between the unit members 110 to close the prefabricated steel tube 100.

이상에서 본 발명은 구체적인 실시예를 참조하여 상세히 설명되었으나, 실시예는 본 발명을 예시하기 위한 것일 뿐이므로, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 치환, 부가 및 변형된 실시 형태들 역시 아래에 첨부한 특허청구범위에 의하여 정하여지는 본 발명의 보호범위에 속한다고 할 것이다.The present invention has been described in detail above with reference to specific embodiments, but the embodiments are only for illustrating the present invention, and thus the embodiments substituted, added, and modified within the scope without departing from the spirit of the present invention are also described below.
