좌굴방지부를 구비한 철골가새{IRON FRAME BRACE HAVING BUCKING PROTECTION PART}Steel frame brace with buckling prevention part {IRON FRAME BRACE HAVING BUCKING PROTECTION PART}

본 발명은 좌굴방지부를 구비한 철골가새에 관한 것으로, 더욱 상세하게는, 기존 철골가새에 비하여 단면적을 감소시킴으로써 공간활용도를 높이고 구조물의 좌굴을 방지함으로써 지진하중이나 풍하중과 같은 횡력에 대한 에너지를 안정적으로 소산할 수 있는 좌굴방지부를 구비한 철골가새에 관한 것이다. The present invention relates to a steel brace having a buckling prevention portion, and more particularly, to reduce the cross-sectional area compared to the existing steel brace to increase the space utilization and to prevent buckling of the structure to stabilize the energy for the lateral force such as earthquake load or wind load It relates to a steel brace having a buckling prevention portion that can dissipate.

일반적으로 철골구조를 갖는 건축물에서는 지진과 풍하중과 같은 수평하중에 대한 기둥-보 골조의 횡강성을 확보하기 위해 철골가새(Brace)를 설치하는 경우가 있다.In general, a steel frame structure may be provided with steel braces to secure the lateral stiffness of column-beam frames against horizontal loads such as earthquakes and wind loads.

도 1은 종래의 철골가새가 골조에 설치된 구조를 도시한 평면도이고, 도 2는 도 1의 'Ⅱ-Ⅱ' 선에 따른 철골가새의 내부구조를 도시한 횡단면도이다. 1 is a plan view showing the structure of a conventional steel braced is installed in the frame, Figure 2 is a cross-sectional view showing the internal structure of the steel frame according to the 'II-II' line of FIG.

도 1에 도시한 바와 같이, 종래의 철골가새가 골조에 설치된 구조는, 기둥(110) 골조와 보(120) 골조가 접촉하는 모서리부분과, 기둥(110) 골조와 지면이 접속하는 부분에 각각 가새 플레이트(140)를 각각 설치하고, 가새 플레이트(140)와 철골가새(130)가 용접에 의하여 연결되는 구조를 갖는다. As shown in FIG. 1, a structure in which a conventional steel brace is installed in a frame includes a corner portion where the pillar 110 frame and the beam 120 frame contact each other, and a portion where the pillar 110 frame and the ground connect to each other. Each brace plate 140 is installed, and the brace plate 140 and the steel brace 130 are connected by welding.

그런데, 이러한 종래의 철골가새가 골조에 설치된 구조에서는, 수평하중이 작용하는 경우는, 철골가새(130)는 압축력 혹은 인장력을 받게 되고, 철골가새(130)의 축방향 강성이 매우 크므로 골조전체의 횡강성이 크게 되어 안정된 구조를 실현할 수 있으나, 철골가새(130)의 좌굴 내력이상의 힘이 작용하게 되면, 철골가새(130)의 좌굴에 의해 철골가새(130)가 받을 수 있는 내력은 순간적으로 급격하게 떨어져 대지진이 발생하여 좌굴 내력이상의 하중이 작용하였을 때에는 철골가새(130) 골조는 매우 불안정한 구조가 될 가능성이 매우 높다는 문제점이 있다. By the way, in the structure in which the conventional steel braces are installed in the frame, when the horizontal load is applied, the steel braces 130 are subjected to compressive or tensile force, and the axial rigidity of the steel braces 130 is very large, so that the whole frame The lateral stiffness of the large can achieve a stable structure, but when a force greater than the buckling strength of the steel brace 130 is applied, the strength that can be received by the steel brace 130 by the buckling of the steel brace 130 instantaneously When a large earthquake suddenly falls and a load of more than the buckling strength is applied, the structure of the steel braced 130 is very likely to become a very unstable structure.

또한, 종래의 철골가새(130)는 기둥(110) 골조 및 보(120) 골조와 연결되어 설치되는 철골가새(130)가 하중을 분담하도록 설계하여야 하기 때문에 기둥(110) 골조와, 보(120) 골조와 같은 주요부재가 손상을 입을 가능성이 있고, 그러한 구조시스템을 내진 설계에 적용하기 위해서는 설계절차가 복잡해지고, 항복 메카니즘을 제어하기에는 어려운 점이 많다는 문제점이 있다. In addition, the conventional steel brace 130 is a pillar 110 and the beam 120, because the steel brace 130 installed in connection with the frame and the beam 120 should be designed to share the load, the frame 110 and the beam 120 There is a problem that the main members such as the frame may be damaged, and the design procedure is complicated to apply such a structural system to the seismic design, and it is difficult to control the yield mechanism.

상기와 같은 점을 감안하여 안출한 본 발명의 목적은, 기존 철골가새에 비하여 단면적을 감소시킴으로써 공간활용도를 높이고 구조물의 좌굴을 방지함으로써 지진하중이나 풍하중과 같은 횡력에 대한 에너지를 안정적으로 소산할 수 있는 좌굴방지부를 구비한 철골가새를 제공함에 있다.The object of the present invention devised in view of the above point, it is possible to stably dissipate energy for the lateral force such as earthquake load or wind load by increasing the space utilization and preventing the buckling of the structure by reducing the cross-sectional area compared to the existing steel brace In providing a steel brace with a buckling prevention portion.

상기와 같은 본 발명의 목적을 달성하기 위한 좌굴방지부를 구비한 철골가 새는, 일정한 내부공간을 형성하는 관상의 강관과; 상기 강관의 내부공간에 설치되는 중심부재와; 상기 강관을 기둥이나 보와 같은 골조에 고정 거치시키도록 상기 강관의 양측 단부에 구비되는 거치부재로 구성되는 철골가새에 있어서, 상기 강관과 상기 중심부재 사이의 공간에 구비되며 일측면이 상기 중심부재의 외면에 고정 결합되고 타측면이 상기 강관의 내면과 접촉되는 복수의 강봉으로 이루어지는 좌굴방지부를 포함하여 구성되는 것을 특징으로 한다.Steel tube with a buckling prevention portion for achieving the object of the present invention as described above, the tubular steel pipe to form a constant internal space; A core material installed in the inner space of the steel pipe; In the steel brace composed of a holding member provided on both ends of the steel pipe to fix the steel pipe to a frame such as a column or beam, provided in the space between the steel pipe and the central material and one side is the central material It is fixed to the outer surface of the other side is characterized in that it comprises a buckling prevention portion consisting of a plurality of steel rods in contact with the inner surface of the steel pipe.

이상에서 살펴본 바와 같이 본 발명에 의한 좌굴방지부를 구비한 철골가새는, 지진하중이나, 풍하중과 같은 횡력이 건축구조물에 가해질 경우 에너지를 안정적으로 소산할 수 있는 효과가 있다. As described above, the steel brace having the anti-buckling portion according to the present invention has an effect of stably dissipating energy when a lateral force such as an earthquake load or wind load is applied to the building structure.

Filled with concrete 133 to have a structure of hardened.

그러나 본 발명은 기존의 비좌굴가새와 비교하여 콘크리트를 사용하지 않는 건식 공법이 사용되므로, 시공의 정밀도가 비교적 덜 요구되므로, 제작이 간편하고 일반 시공기술자가 쉽게 제작할 수 있는 효과가 있다. However, the present invention uses a dry method that does not use concrete in comparison with the existing non-buckling bracing, because the construction precision is relatively less required, the production is easy and there is an effect that can be easily manufactured by general construction technicians.

아울러, 기존의 철골가재가 좌굴에 저항하기 위하여 단면이 커지는 것에 비하여 좌굴을 방지함으로써 가새의 단면적을 상당히 줄일 수 있으므로 공간 활용도를 높일 수 있는 효과가 있다. In addition, compared to the conventional steel frame to resist buckling, the cross section of the brace to prevent the buckling to significantly reduce the cross-sectional area of the brace, thereby increasing the space utilization.
