본 발명은 철골구조물에서의 층고절감형 바닥구조에 관한 것이며, 특히, H형강보의 상부 플랜지에 딥 데크를 결합시켜 바닥층의 두께를 감소시키는 층고절감형 바닥구조에 관한 것이다.The present invention relates to a floor-reduced floor structure in a steel structure, and more particularly, to a floor-reduced floor structure for reducing the thickness of the bottom layer by coupling a dip deck to the upper flange of the H-beam.

일반적인 철골구조물의 바닥구조는 철골구조(steel structure) 또는 철골콘크리트구조(reinforced concrete structure)를 기반으로 구축된다. 상기 바닥구조는 바닥골조를 형성하는 철골 콘크리트부와, 이런 철골 콘크리트부의 상부에 설치되는 온돌층 또는 바닥마감재 및, 철골 콘크리트부의 하부에 설치되는 천정마감부로 구성된다. 그리고, 바닥구조에서 철골 콘크리트부는 다음의 도 1과 같이 구성 설치된다.The floor structure of the general steel structure is constructed based on a steel structure (steel structure) or steel reinforced concrete (reinforced concrete structure). The floor structure is composed of a steel concrete part to form a floor frame, an ondol layer or a floor finishing material installed on the upper portion of the steel concrete portion, and a ceiling finishing portion installed on the lower portion of the steel concrete portion. And, the steel frame concrete portion in the floor structure is installed as shown in FIG.

도 1은 종래기술에 따른 철골구조물에서 H형강보와 데크로 형성된 바닥구조의 일부 단면도이고, 도 2는 도 1에 도시된 바닥구조에서 콘크리트가 타설되기 전에 H형강보와 데크가 설치된 상태를 나타낸 일부 사시도이다.1 is a partial cross-sectional view of the floor structure formed with H-beams and decks in steel structures according to the prior art, Figure 2 shows a state in which the H-beams and decks are installed before concrete is poured in the floor structure shown in FIG. Some perspective view.

도 1 및 도 2에 도시된 바와 같이, 철골구조물에는 벽체의 기둥으로 사용되는 다수개의 스틸 스터드들 사이에 보가 설치 연결된다. 그리고, 보에는 강성을 고려하여 일반적으로 H형강이 주로 사용되는데, 이런 H형강보(10)가 설치되는 기둥과 기둥 사이가 넓은 구조물에는 H형강보(10)에 발생하는 처짐을 억제시키기 위해 웨브 길이가 긴 H형강보(10)가 사용되기도 한다. As shown in Figure 1 and 2, the steel structure is connected to the beam between the plurality of steel studs used as the pillar of the wall. In general, H-beams are generally used in consideration of the rigidity of the beams, and in a structure in which the H-beams 10 are installed in a wide structure between the pillars and the pillars, the webs for suppressing the deflections occurring in the H-beams 10 are provided. Long H-shaped steel beam 10 may be used.

그리고, 철골구조물의 바닥구조에는 상기와 같은 다수개의 H형강보(10)들이 일정 간격으로 배열 설치되고, 인접한 한 쌍의 H형강보(10) 사이에는 다수개의 데크(11)들이 H형강보(10)의 상부 플랜지에 그 길이방향을 따라 설치된다. In addition, a plurality of H-shaped steel beams 10 are arranged at regular intervals in the bottom structure of the steel frame structure, and a plurality of decks 11 are H-shaped steel beams between a pair of adjacent H-shaped steel beams 10. 10) is installed along the longitudinal direction of the upper flange.

그리고, 상기 바닥구조에 사용되는 데크(11)는 일반적인 절곡된 형상의 강판이며, H형강보(10)의 상부 플랜지에 데크(11)가 거치되는 경우에는 데크(11)의 절곡된 부위에서 빈 공간이 존재하게 된다. 그래서, H형강보(10)와 데크(11)로 형성된 바닥골조에는 타설되는 콘크리트(13)가 상기 데크(11)의 절곡된 부위를 통해 하부로 흘러 나가지 못하도록, H형강보(10)와 데크(11)가 접하는 빈 공간에 캡(15)을 설치한다. The deck 11 used for the floor structure is a steel plate having a general bent shape, and when the deck 11 is mounted on the upper flange of the H-shaped steel beam 10, the deck 11 is empty at the bent portion of the deck 11. Space exists. Thus, in the bottom frame formed of the H-beams 10 and the deck 11, the concrete 13 to be poured so as not to flow down through the bent portion of the deck 11, H-beams 10 and the deck The cap 15 is provided in the empty space which (11) contacts.

하지만, 상기와 같이 구성된 철골구조물의 바닥구조는 H형강보(10)의 상부에 데크(11) 뿐만 아니라, 타설되는 콘크리트(13)와, 온돌층과 바닥마감재까지 적층되기 때문에, 바닥구조의 두께가 두꺼워지는 큰 문제점이 있다. However, the floor structure of the steel structure configured as described above is not only deck 11 on top of the H-beams 10, but also the concrete 13, the ondol layer and the floor finishing material is stacked, the thickness of the floor structure There is a big problem of thickening.

또한, 상기 바닥구조는 H형강보(10)가 외부에 노출되기 때문에, 부식방지 등을 위한 내화피복처리를 해야 하는 문제점이 있다.In addition, since the floor structure is exposed to the outside of the H-shaped steel beam 10, there is a problem that a fireproof coating treatment for corrosion prevention, etc. should be performed.

그래서, 대한민국 특허공개 제 2000-0038840호에 기술된 바닥구조의 종래기술에서는 층고절감을 위해 바닥구조의 두께를 감소시키는 바닥구조를 기술하고 있다. 아래에서는 상기 대한민국 특허공개 제 2000-0038840호의 기술내용에 대하여 도 3 및 도 4를 참조해 가면서 설명하겠다.Thus, the prior art of the floor structure described in Korean Patent Laid-Open No. 2000-0038840 discloses a floor structure for reducing the thickness of the floor structure to reduce the floor. Hereinafter, the technical contents of the Korean Patent Publication No. 2000-0038840 will be described with reference to FIGS. 3 and 4.

도 3 및 도 4는 도 1에 도시된 바닥구조의 두께를 감소시킨 종래기술의 다른 실시예를 각각 나타낸 일부 단면도들이다.3 and 4 are some cross-sectional views respectively showing another embodiment of the prior art in which the thickness of the floor structure shown in FIG. 1 is reduced.

도 3에 도시된 바와 같이, 종래기술의 다른 실시예에 따른 층고절감형 바닥구조는 H형강보(20a)의 하부 플랜지에 그 하부 플랜지보다 넓은 폭을 갖는 강판(26)을 용접한다. 그리고, 강판(26)이 접합된 H형강보(20a)의 하부 플랜지에 딥 데크(21)를 거치하고, 콘크리트(23)를 타설한다. As shown in FIG. 3, the layer-reduced floor structure according to another embodiment of the prior art welds the steel plate 26 having a wider width than the lower flange to the lower flange of the H-shaped steel beam 20a. Then, the deep deck 21 is mounted on the lower flange of the H-shaped steel beam 20a to which the steel plate 26 is joined, and the concrete 23 is poured.

상기 종래의 다른 실시예는 바닥구조의 두께가 감소하는 효과가 있지만, 딥 데크(21) 및 콘크리트(23)와 같은 바닥구조의 하중이 H형강보(20a)의 강판(26)에 작용하기 때문에, 구조적 안전성에 문제점이 있다.Another conventional embodiment has the effect of reducing the thickness of the floor structure, but because the load of the floor structure such as the deep deck 21 and concrete 23 acts on the steel plate 26 of the H-beams 20a However, there is a problem in structural safety.

그리고, 도 4에 도시된 바와 같이, 종래기술의 또 다른 실시예에 따른 층고절감형 바닥구조는 하부 플랜지 폭이 넓은 H형강보(20b)를 사용한다. 그리고, H형강보(20b)의 하부 양 플랜지에는 딥 데크(21)를 각각 거치하고, 콘크리트(23)를 타설한다.And, as shown in Figure 4, the high-floor floor structure according to another embodiment of the prior art uses the H-shaped steel beam 20b having a wide bottom flange width. Then, each of the lower decks of the H-shaped steel beams 20b is mounted with the deep decks 21, and the concrete 23 is poured.

하지만, 이런 하부 플랜지가 넓은 H형강보(20b)를 이용한 바닥구조는 기존 대량 생산되는 규격화된 H형강보를 사용할 수 없는 단점이 있다. 그리고, 기둥과 다른 기둥 사이가 넓은 장스팬 구조물은 웨브가 긴 H형강보를 사용하기 때문에, H형강보의 웨브 길이에 대응하는 높이를 가진 딥 데크를 사용해야 하는 단점이 있으며, H형강보의 웨브 길이에 대응하는 높이의 데크를 사용하지 않는 바닥구조는 콘크리트(23)의 윗면 높이에 맞춰 필요 이상으로 콘크리트 슬라브를 시공해야 하는 단점이 있다. However, the bottom structure using a wide H-shaped steel beam (20b) of the lower flange has a disadvantage that can not use the standardized H-shaped steel beam produced in the past. In addition, since the long span structure between the pillar and the other pillar has a long H-beam, the web has a disadvantage of using a deep deck having a height corresponding to the web length of the H-beam. The floor structure does not use a deck of a height corresponding to the disadvantage that the concrete slab must be constructed more than necessary to match the top height of the concrete (23).

본 발명은 앞서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 제공된 것으로서, H형강보의 상부 플랜지에 연결부재를 용접 결합시키고, 이런 연결부재에 딥 데크를 거치 결합시켜 바닥층의 두께를 감소시키는 층고절감형 바닥구조를 제공하는 데 그 목적이 있다.The present invention has been provided to solve the problems of the prior art as described above, and welded coupling member to the upper flange of the H-beam, and through the deep deck to the coupling member to reduce the thickness of the bottom layer to reduce the thickness of the bottom layer The purpose is to provide a type floor structure.

앞서 설명한 바와 같은 목적을 달성하기 위한 본 발명의 층고절감형 바닥구조는 철골구조물에서 기둥과 다른 기둥 사이에 연결 설치되는 H형강보와, 상기 H형강보의 길이방향을 따라 상기 H형강보에 거치 결합되는 데크 및, 상기 데크의 상부에 타설되는 콘크리트를 포함한다. 상기 H형강보의 상부 양 플랜지에는 연결부재가 상기 H형강보의 외측방향으로 돌출되게 각각 접합되고, 상기 연결부재에는 상기 데크가 거치 결합된다.Floor-saving floor structure of the present invention for achieving the object as described above is mounted on the H-beams along the longitudinal direction of the H-beams and the H-beams are installed between the pillars and other columns in the steel structure A deck to be joined, and concrete poured on top of the deck.

Floor-saving floor structure of the present invention is installed between the H-shaped steel beam 30 is mass-produced and standardized between the pillar and the other pillar in the steel structure. And, when the H-shaped steel beam 30 is installed in a wide structure between the pillar and the other pillar, in order to suppress the deflection generated in the H-shaped steel beam 30, H-shaped steel beam 30 having a long web length You can also use

그리고, H형강보(30)의 상부 양 플랜지에는 H형강보(30)의 길이방향을 따라 일정 간격으로 연결부재(32)인 다수개의 철물들이 각각 접합된다. 즉, 연결부재(30)는 H형강보(30)의 상부 플랜지에서 H형강보(30)의 내측면에 접합된다. 그리고, 연결부재(30)는 H형강보(30)의 플랜지 및 웨브에 용접되던지, H형강보(30)의 플랜지에만 용접될 수 있다. 또한, 연결부재(32)는 정형화된 크기와 형상을 가진 철물을 사용하지 않아도 무방하지만, H형강보(30)에 용이하게 용접 결합되도록 H형강보(30)와 같은 재질인 것이 바람직하다. 그리고, 연결부재(32)는 H형강보(30)의 외측방향으로 돌출되게 접합되어야 하며, 돌출되는 연결부재(32)의 크기는 시공되는 바닥구조의 여건에 따라 달리한다. 그리고, 돌출된 연결부재(32)에는 딥 데크(31)가 거치 결합된다.In addition, the upper flanges of the H-shaped steel beams 30 are joined to a plurality of hardware, which are the connecting members 32 at regular intervals, respectively, along the longitudinal direction of the H-shaped steel beams 30. That is, the connecting member 30 is joined to the inner surface of the H-beams 30 in the upper flange of the H-beams 30. In addition, the connecting member 30 may be welded to the flange and the web of the H-shaped steel beam 30, or may be welded only to the flange of the H-shaped steel beam 30. In addition, the connecting member 32 may be made of a material having a standardized size and shape, but may be made of the same material as the H-shaped steel beam 30 so as to be easily welded to the H-shaped steel beam 30. And, the connecting member 32 is to be bonded to protrude in the outward direction of the H-shaped steel beam 30, the size of the connecting member 32 protruding varies depending on the conditions of the floor structure being constructed. Then, the deep deck 31 is coupled to the protruding connection member 32.

도 6은 도 5에 도시된 바닥구조에서의 딥 데크를 나타낸 사시도이다.FIG. 6 is a perspective view illustrating a deep deck in the floor structure illustrated in FIG. 5.

도 5 및 도 6에 도시된 바와 같이, 딥 데크(31)는 철골구조물에서 거푸집과 같이 콘크리트 슬라브가 형성될 수 있도록, 콘크리트(33)를 지지하는 역할을 한다. 이런 딥 데크(31)는 굴곡된 형상의 굴곡부(36)와, 상기 돌출된 연결부재(32)에 접하는 거치부(37)로 구성된다. 그리고, 본 발명의 층고절감형 바닥구조에는 딥 데크(31)에 비해 높이가 작은 일반 데크를 사용해도 무방하나, 일반 데크를 사용하는 경우에는 바닥구조에 콘크리트의 시공높이만큼 필요 이상으로 콘크리트 슬라브가 타설 시공해야 함으로, H형강보(30)의 웨브 길이보다 약간 작은 높이의 딥 데크(31)를 이용한다.As shown in Figure 5 and 6, the deep deck 31 serves to support the concrete 33, so that the concrete slab can be formed in the steel structure, such as formwork. The deep deck 31 is composed of a curved portion 36 of the curved shape, and the mounting portion 37 in contact with the protruding connecting member 32. In addition, although the floor height reduction floor structure of the present invention may use a general deck having a smaller height than the deep deck 31, when using a general deck, concrete slabs are more than necessary as the construction height of the concrete in the floor structure. Since the construction should be poured, a deep deck 31 of a height slightly smaller than the web length of the H-beams 30 is used.

그리고, 바닥구조에는 H형강보(30)에 딥 데크(31)가 거치된 상태에서 타설되는 콘크리트(33)가 하부로 흘러 내리지 못하도록, 거치부(37)의 하부 빈 공간에 캡이 삽입 설치된다. In addition, a cap is inserted into the bottom structure so that the concrete 33 being poured in the state where the deep deck 31 is mounted on the H-shaped steel beam 30 does not flow down. .
