Description

층고저감형 바닥구조{FLOOR CONSTRUCTION FOR LOWERING STORY-HEIGHT}FLOOR CONSTRUCTION FOR LOWERING STORY-HEIGHT}

본 발명은 층고저감형 바닥구조에 관한 것으로, 보다 상세하게는 강관기둥에 접합되는 보부재와 함께 바닥을 형성하는 층고저감형 바닥구조에 관한 것이다.The present invention relates to a floor-reduced floor structure, and more particularly, to a floor-reduced floor structure that forms a floor together with a beam member joined to a steel pipe column.

일반적으로 고층건물의 시공시, 전체 건물높이를 낮추기 위해서는 설계요구사항에 따른 실내높이를 제외한 보와 슬라브, 그리고 천전공간으로 구성된 층간 높이를 낮추는 것이 중요하다.In general, it is important to lower the height between floors consisting of beams, slabs and ceiling spaces, excluding interior heights, according to design requirements.

한편, 일반적인 철골건물에 있어서, 슬라브 바닥하중을 철골보가 지지하도록 설계된다. 이와 같은 구조의 바닥구조체는 슬라브의 높이에 철골보의 높이가 더해져 층간 높이가 높아지며 건축물이 고층인 경우 노출보에 대한 내화처리를 위한 공간이 추가됨에 따라서 층간 높이가 높아지는 단점이 있다.On the other hand, in a typical steel frame building, the cheolgolbo is designed to support the slab floor load. The floor structure of such a structure has the disadvantage that the height of the slab is added to the height of the slab and the height of the floor increases, and the height of the floor increases as the space for fire treatment of the exposed beam is added when the building is a high floor.

이러한 문제점을 해소하기 위하여 하부 플랜지에 데크부재를 거치하여 슬라브를 보부재의 웨브 높이 이상으로 시공하도록 하는 형태의 철골보 부재가 다양하게 개발되어 사용되고 있다.In order to solve this problem, various types of steel golbo members have been developed and used to mount the slab on the lower flange to construct the slab above the web height of the beam member.

하지만, 상기한 철골보 부재를 통한 시공시 보의 크기가 커지게 되어 전체 높이에 해당하는 두께의 바닥슬라브는 비합리적인 시공이 되기 쉬우며, 바닥 아랫 면의 높이가 보의 하부플랜지의 높이와 동일하게 시공됨으로서 천장면에 등기구나 배선등에 필요한 추가 공간의 확보가 어려워지는 단점을 가지고 있다.However, when the construction of the beam through the steel cheolgolbo member becomes large, the floor slab having a thickness corresponding to the overall height is easy to be unreasonable construction, the height of the bottom of the floor is the same as the height of the lower flange of the beam As a result, it is difficult to secure additional space required for lighting and wiring on the ceiling.

따라서, 층간 높이를 낮추면서 시공비용 및 시공효율을 향상시키는 바닥구조가 필요한 실정이다.Therefore, there is a need for a floor structure that improves the construction cost and construction efficiency while lowering the height between floors.

본 발명은 층간의 높이를 감소시킬 수 있는 층고저감형 바닥구조를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a floor height reduction floor structure that can reduce the height between floors.

본 발명에 따른 층고저감형 바닥구조는 수평부재와 상기 수평부재로부터 연장형성되는 수직부재를 구비하는 층고저감형 보부재와, 상기 보부재의 상부에 타설되는 슬라브와 상기 슬라브의 내부에 배치되도록 매설되는 강도보강근을 구비하는 바닥부, 및 상기 보부재와 상기 바닥부에 구비되는 강도보강근을 연결하는 접합보강부재를 포함한다.The floor-reduced floor structure according to the present invention has a floor-reduced beam member having a horizontal member and a vertical member extending from the horizontal member, and a slab placed on top of the beam member and embedded to be disposed inside the slab. And a joint reinforcing member for connecting the beam reinforcing bar provided with the beam member and the bottom reinforcing bar having a strength reinforcement.

상기 강도보강근은 일측이 강관기둥에 접합되며 외력에 저항할 수 있도록 고강도 철근으로 이루어질 수 있다.The reinforcing reinforcement may be made of high strength reinforcing bar so that one side is joined to the steel pipe pillar and can resist external forces.

상기 접합보강부재는 상기 수직부재와 상기 강도보강근을 연결하도록 접합되는 플레이트 형상을 가지며, 복수개가 접합될 수 있다.The joint reinforcing member has a plate shape to be joined to connect the vertical member and the strength reinforcing muscle, a plurality may be joined.

상기 보부재는 H 형강보에 구비되는 웨브에서 이등분으로 절단된 H 형강보 형상으로 이루어질 수 있다.The beam member may be formed in an H-shaped steel beam shape cut into bisection in a web provided in the H-shaped steel beam.

본 발명에 따르면, 절단된 H 형강보 형상으로 이루어진 보부재를 통해 바닥을 구성하는 철골 골조의 높이를 감소시킬 수 있으므로, 층고를 저감할 수 있는 효과가 있다.According to the present invention, it is possible to reduce the height of the steel frame constituting the floor through the beam member made of a cut H-shaped steel beam shape, there is an effect that can reduce the height.

또한, 절단된 H 형강보 형상으로 이루어진 보부재를 통해 시공비용을 감소시킬 수 있다.In addition, the construction cost can be reduced through the beam member made of a cut H-shaped steel beam shape.

도 1 내지 도 3을 참조하면, 층고저감형 바닥구조(100)는 일예로서, 보부재(120), 바닥부(130), 및 접합보강부재(160)를 포함한다.1 to 3, the floor height reduction floor structure 100 includes, as an example, a beam member 120, a bottom portion 130, and a joint reinforcing member 160.

보부재(120)는 강관기둥(10)에 접합된다. 한편, 강관기둥(10)은 일예로서 각형강관기둥일 수 있으며, 보다 자세하게는 사각형 단면을 가진 각형강관기둥일 수 있다.Beam member 120 is bonded to the steel pipe column (10). Meanwhile, the steel pipe column 10 may be, for example, a square steel pipe column, and more particularly, a square steel pipe column having a rectangular cross section.

또한, 보부재(120)는 용접에 의해 강관기둥(10)에 접합될 수 있으며, 도 1에 도시된 바와 같이, 일예로서 강관기둥(10)의 대향되도록 배치되는 양측면에 보부재(120)가 접합될 수 있다.In addition, the beam member 120 may be joined to the steel pipe pillar 10 by welding, and as shown in FIG. 1, as an example, the beam member 120 may be disposed on both side surfaces of the steel pipe pillar 10 to face each other. Can be bonded.

다만, 이에 한정되지 않으며, 보부재(120)는 강관기둥(10)의 적어도 일측면 에 접합될 수 있다.However, the present invention is not limited thereto, and the beam member 120 may be joined to at least one side of the steel pipe pillar 10.

한편, 보부재(120)는 수평부재(122)와,수평부재(122)에 수직하게 배치되어 강관기둥에 접합되는 수직부재(124)를 구비할 수 있다. 즉, 보부재(120)의 수평부재(122)는 강관기둥(120)의 폭방향으로 접합되며, 수평부재(122)의 상면으로부터 연장되도록 형성되는 수직부재(124)는 강관기둥(120)의 길이방향으로 접합된다.Meanwhile, the beam member 120 may include a horizontal member 122 and a vertical member 124 disposed perpendicular to the horizontal member 122 and joined to the steel pipe pillar. That is, the horizontal member 122 of the beam member 120 is joined in the width direction of the steel pipe pillar 120, the vertical member 124 is formed to extend from the upper surface of the horizontal member 122 of the steel pipe pillar 120 It is joined in the longitudinal direction.

일예로서, 보부재(120)는 H 형강보에 구비되는 웨브에서 이등분으로 절단된 H 형강보 형상으로 이루어질 수 있다.As an example, the beam member 120 may be formed in an H-shaped steel beam shape cut in bisection in the web provided in the H-shaped steel beam.

바닥부(130)는 보부재(120)의 상부에 타설되는 슬라브(140)와, 슬라브(140)의 내부에 배치되도록 매설되는 강도보강근(150)을 구비할 수 있다.The bottom portion 130 may include a slab 140 that is placed on the upper portion of the beam member 120 and a strength reinforcement 150 that is embedded to be disposed inside the slab 140.

슬라브(140)는 보부재(120)의 수평부재(122)와 평행을 이루도록 타설되며, 콘크리트로 구성될 수 있다.The slab 140 is poured in parallel with the horizontal member 122 of the beam member 120, it may be composed of concrete.

한편, 강도보강근(150)은 일측이 강관기둥(10)에 접합되며, 외력에 저항할 수 있도록 고강도 철근으로 이루어질 수 있다. 즉, 외력이 가해지는 경우 강도보강근(150)은 보부재(120)와 함께 하중을 강관기둥(10)에 전달할 수 있도록 고강도 철근으로 이루어질 수 있다.On the other hand, the strength reinforcement 150 is one side is joined to the steel pipe column 10, it may be made of high strength reinforcement to resist external forces. That is, when an external force is applied, the strength reinforcement 150 may be made of high strength reinforcement to transfer the load to the steel pipe column 10 together with the beam member 120.

이에 따라, 절단된 H 형강보 형상으로 이루어진 보부재(120)와 함께 강도보강근(150)은 건물의 골조 역할을 수행한다.Accordingly, the strength reinforcement 150 together with the beam member 120 formed in the cut H-shaped beam shape serves as a skeleton of the building.

한편, 강도보강근(150)은 보부재(120)의 상부에 다수개가 일정 간격을 가지도록 구비될 수 있다. 즉, 전달되는 외력을 분산하여 부담할 수 있도록 강도보강근(150)이 슬라브(140)의 내부에 배치된다.On the other hand, the strength reinforcement 150 may be provided on the upper portion of the beam member 120 to have a predetermined interval. That is, the strength reinforcement 150 is disposed inside the slab 140 so as to distribute and bear the external force transmitted.

또한, 도면에는 도시되지 않았으나 슬라브(140) 내부에는 콘크리트의 타설을 위한 구조철근이 배근되어 있으며, 상기한 강도보강근(150)은 슬라브(140)를 지지하도록 구비되는 구조철근과는 구별된다. In addition, although not shown in the drawing, the structural reinforcing bar for placing concrete is placed inside the slab 140, and the strength reinforcing bar 150 is distinguished from the structural reinforcing bar provided to support the slab 140.

접합보강부재(160)은 보부재(120)와 바닥부(130)에 구비되는 강도보강근(150)을 연결한다. 즉, 접합보강부재(160)는 보부재(120)의 수직부재(122)와 강도보강근(150)을 연결하도록 일측이 수직부재(122)에 접합되고 타측이 강도보강근(150)에 접합된다.The joint reinforcing member 160 connects the strength reinforcement 150 provided in the reinforcing member 120 and the bottom portion 130. That is, the joint reinforcing member 160 is joined to the vertical member 122 and the other side is joined to the strength reinforcement 150 so as to connect the vertical member 122 and the strength reinforcement 150 of the beam member 120.

한편, 접합보강부재(160)는 플레이트 형상을 가질 수 있으며, 복수개가 구비될 수 있다.On the other hand, the bonding reinforcing member 160 may have a plate shape, it may be provided with a plurality.

이에 따라, 보부재(120)로부터 전달되는 하중이 접합보강부재(160)를 통해 연결된 강도보강근(150)에 전달될 수 있다. 즉, 접합보강부재(160)를 통해 보부재(120)와 강도보강근(150)이 연결되므로, 보부재(120)와 강도보강근(150)은 일체로 거동하여 전달되는 하중을 강관기둥(10)에 전달할 수 있는 것이다.Accordingly, the load transmitted from the reinforcing member 120 may be transmitted to the strength reinforcing muscle 150 connected through the joint reinforcing member 160. That is, since the beam member 120 and the strength reinforcement 150 is connected through the joint reinforcing member 160, the beam member 120 and the strength reinforcement 150 is integrated with the steel pipe pillar (10) Can be delivered to.

더하여, 접합보강부재(160)는 바닥부(130)에 구비되는 슬라브(140)에 매설되며, 이에 따라 접합보강부재(160)는 보부재(120), 강도보강근(150), 슬라브(140)와 일체로 거동할 수 있다.In addition, the joint reinforcing member 160 is embedded in the slab 140 provided in the bottom portion 130, accordingly the joint reinforcing member 160 is a reinforcing member 120, strength reinforcement 150, slab 140 Can be integrated with

따라서, 가해지는 외력을 강관기둥(10)으로 전달할 수 있다.Therefore, the external force applied can be transmitted to the steel pipe column 10.

상기한 바와 같이, 이등분으로 절단된 H 형강보 형상을 가지는 보부재(120)를 통해 층고를 저감할 수 있다.As described above, the height of the floor can be reduced through the beam member 120 having the H-shaped steel beam shape cut into two parts.

더하여, 보부재(120)를 통해 구조물의 골조를 형성하므로, 사용되는 철물의 양을 감소시킬 수 있으므로, 시공비용이 감소될 수 있다.In addition, since the structure of the structure is formed through the beam member 120, since the amount of hardware used can be reduced, the construction cost can be reduced.

그리고, 슬라브(140)와 일체로 거동하는 강도보강근(150)과 접합보강부재(160)를 통해 보부재(120)의 상부측 강도를 보강할 수 있으므로, 층고를 저감할 수 있는 동시에 접합강도를 유지할 수 있다.In addition, since the strength of the upper side of the beam member 120 can be reinforced by the strength reinforcement 150 and the joint reinforcement member 160 which are integral with the slab 140, the height of the floor can be reduced and the bond strength can be reduced. I can keep it.
