본 발명은 철골철근콘크리트 합성구조에 관한 것으로, 더욱 상세하게는 철골 보의 상부플랜지 위로 콘크리트보를 형성시키는 방법으로 철골보와 철근콘크리트슬래브를 합성함으로 강재량의 증가없이도 강성증대가 가능해져 공사비를 절감할 수 있게 되며 나아가 진동에 불리한 철골보의 규격을 극소화한 상태에서도 충분한 강성확보가 가능해져 혐진구조물에 유용하게 적용할 수 있는 철골철근콘크리트 합성구조에 관한 것이다.The present invention relates to a steel reinforced concrete composite structure, and more specifically, by combining a steel beam and reinforced concrete slab by forming a concrete beam over the upper flange of the steel beam, it is possible to increase the rigidity without increasing the amount of steel to reduce construction costs The present invention also relates to a steel reinforced concrete composite structure that can secure useful stiffness even in the state of minimizing the specification of steel golbo, which is disadvantageous to vibration.

철골구조는 건축물의 주요 구조부재로 공장(경우에 따라서는 현장)에서 제작한 철골부재를 리벳, 볼트 또는 용접 등의 접합방식에 의해 조립하여 이루어진 일종의 건식구조를 말한다. 이와 같은 철골구조에 따르면 크레인 등의 양중 장비에 의해 조립식으로 시공하므로 공기를 단축할 수 있게 되고, 고층 건물 및 대규모 스팬 건축물에 적합하여 설계 및 내부 평면구성이 자유로우며, 증,개축이 용이하다는 등의 장점이 수반된다. Steel structure refers to a kind of dry structure made by assembling the steel member manufactured in the factory (in some cases on site) as the main structural member of the building by the joining method such as rivet, bolt or welding. According to the steel structure, it is possible to shorten the air because it is prefabricated by heavy lifting equipment such as crane, and it is suitable for high-rise buildings and large-scale span buildings, and its design and interior plan are free, and it is easy to build and rebuild. Is accompanied by its advantages.

다만, 철골구조에서 다른 구조부재는 건식의 조립식으로 시공되는 것이 일반적이나, 각 구조부재와의 일체화를 위해 슬래브는 철근콘크리트구조의 습식으로 시공되는 것이 일반적이다. 도 1은 이와 같은 통상적인 철골보와 철근콘크리트슬래브의 합성구조를 도시하고 있다.However, in the steel structure, other structural members are generally constructed in a dry assembly type, but the slab is generally constructed in a wet type of reinforced concrete structure for integration with each structural member. Figure 1 shows a composite structure of such a conventional cheolgolbo and reinforced concrete slab.

한편, 도 1과 같은 단순한 형태의 합성구조를 장스팬 구조물에 적용하기 위해서는 강성을 증대시킬 필요가 있으며, 종래에는 철골보의 규격을 확장시키는 방법으로 강성을 증대시키는 것이 일반적이었다. 그러나, 이와 같은 방법은 고가인 강재량을 증대시키는 방법이므로 곧 공사비가 증대되는 문제를 수반하며, 무엇보다도 철골보의 규격에 비례하여 외부 충격에 의한 진동이 그만큼 증폭되므로 반도체 공장, LCD 공장과 같은 혐진구조물에 적용이 어렵다는 문제를 내재하였다. On the other hand, in order to apply the simple structure of the composite structure as shown in Figure 1 in the long span structure, it is necessary to increase the rigidity, it was conventional to increase the rigidity by a method of extending the specification of the cheolgolbo. However, this method is a method of increasing expensive steel materials, which in turn entails an increase in the cost of construction. Above all, the vibration caused by external shocks is amplified in proportion to the specifications of Cheolgolbo. There is a problem that it is difficult to apply to the structure.

이에 기존의 합성구조 형식이 갖는 단점을 보완할 수 있는 새로운 형태의 개발이 필요한 실정이었는 바, 본 발명자들은 이와 같은 점을 감안하여 본 발명과 같은 새로운 형태의 합성구조를 개발하게 되었다.Therefore, it was necessary to develop a new type that can compensate for the shortcomings of the existing synthetic structure type, and the present inventors have developed a new type of synthetic structure in accordance with the present invention.

본 발명은 상기한 종래의 문제를 개선하고자 안출된 것으로서, 철골보의 상부플랜지 위로 콘크리트보를 형성시키는 방법으로 철골보와 철근콘크리트슬래브를 합성함으로 강재량의 증가없이도 강성증대가 가능해져 비교적 저렴한 공사비로 장스팬 구조물에 유용하게 적용할 수 있는 철골철근콘크리트 합성구조를 제공하는데 그 목적이 있다.The present invention has been made to improve the above-described problems, by combining the steel beams and reinforced concrete slab by forming a concrete beam on the upper flange of the cheolgolbo, it is possible to increase the rigidity without increasing the amount of steel material, the span is relatively low construction cost The purpose is to provide a steel reinforced concrete composite structure that can be usefully applied to the structure.

본 발명의 다른 목적은 진동에 불리한 철골보의 규격을 극소화한 상태에서도 충분한 강성확보가 가능해져 혐진구조물에 유용하게 적용할 수 있는 철골철근콘크리트 합성구조를 제공하는 것이다.Another object of the present invention is to provide a steel reinforced concrete composite structure that can be securely used in a damped structure is possible to secure sufficient rigidity even in the state of minimizing the specifications of the cheolgolbo against vibration.

상기한 목적달성을 위해, 본 발명은 상·하부플랜지 및 웨브로 이루어지는 철골보; 상기 철골보의 상부플랜지 위로 시공되는 콘크리트보; 및, 상기 콘크리트보 위 수평방향으로 콘크리트보와 일체화 시공되는 철근콘크리트슬래브;를 포함하여 구성되는 것을 특징으로 하는 철골철근콘크리트 합성구조를 제공한다. In order to achieve the above object, the present invention is cheolgolbo consisting of upper, lower flanges and web; Concrete beams are constructed on the upper flange of the cheolgolbo; And, reinforced concrete slab which is constructed integrally with the concrete beam in the horizontal direction on the concrete beam; provides a steel reinforced concrete composite structure comprising a.

이때, 상기 콘크리트보는 상기 철골보의 상부플랜지 양단부 위로 철골보의 길이방향을 따라 한쌍의 측면플레이트를 세워서 접합 설치한 후 한쌍의 측면플레이트에 의해 형성된 공간 내에 콘크리트가 채워짐으로 시공될 수 있으며, 특히 상기 한쌍의 측면플레이트는 상향하여 점점 간격이 벌어지도록 경사지게 설치될 수 있다. 나아가, 상기 철골보의 상부플랜지 상부면에 시어코넥터가 접합 설치되도록 구성할 수 있다. In this case, the concrete beam can be constructed by filling the concrete in the space formed by the pair of side plates after installing a pair of side plates in the longitudinal direction of the cheolgolbo on both ends of the upper flange of the cheolgolbo, especially the pair of The side plate may be installed to be inclined so as to be gradually spaced upward. Further, the sheath connector may be configured to be bonded to the upper surface of the upper flange of the cheolgolbo.

이하, 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

도 2는 본 발명에 따른 철골철근콘크리트 합성구조를 도시한 도면이고 도 3은 본 발명의 철골철근콘크리트 합성구조에 적용되는 철골보를 도시한 도면이며, 도시하고 있는 바와 같이 본 발명은 철골구조와 철근콘크리트구조를 합성한 합성구조로서 통상의 철골보 상부플랜지(10a)와 철근콘크리트슬래브(30) 사이에 콘크리트보(20)가 형성된다는데 기술적 특징이 있다. 결국, 본 발명은 전체적으로 철근콘크리트T형보와 그 아래의 철골보의 합성구조와 흡사한 구조형식으로 완성된다고 할 수 있다.Figure 2 is a view showing a steel reinforced concrete composite structure according to the present invention and Figure 3 is a view showing a steel cheolgolbo applied to the steel reinforced concrete composite structure of the present invention, as shown in the present invention the steel structure and reinforcing steel It is a technical feature that the concrete beam 20 is formed between the conventional steel cheolgolbo upper flange (10a) and the reinforced concrete slab 30 as a synthetic structure synthesized concrete structure. After all, the present invention can be said to be completed in a structural form similar to the composite structure of the reinforced concrete T-beams and the steel cheolgolbo below.

철골보(10)는 상부플랜지(10a), 하부플랜지(10b) 및 웨브(10c)로 이루어지 며, 이러한 예로는 가장 보편적인 H형강이 있다. Cheolgolbo 10 is composed of the upper flange (10a), the lower flange (10b) and the web (10c), this example is the most common H-shaped steel.

콘크리트보(20)는 상기 철골보의 상부플랜지(10a) 위로 시공되어 구조적으로 철골보(10)를 보완하는 역할을 한다. Concrete beam 20 is constructed above the upper flange (10a) of the cheolgolbo and serves to structurally complement the cheolgolbo (10).

콘크리트보(20)의 시공을 위해 본 발명에서는 도 3과 같이 한쌍의 측면플레이트(21)가 접합된 상태의 철골보(10)를 제안하고 있다. 즉, 철골보의 상부플랜지(10a) 양단부 위로 철골보(10)의 길이방향을 따라 한쌍의 측면플레이트(21)를 세워서 접합함으로 한쌍의 측면플레이트(21) 사이에 공간이 형성되도록 한 것이다. 그 결과 한쌍의 측면플레이트(21)는 콘크리트보(20)를 형성하기 위한 일종의 영구거푸집이 되며, 그 사이 공간 내에 콘크리트가 채워짐으로 콘크리트보(20)로 완성된다. For the construction of the concrete beam 20, the present invention proposes a cheolgolbo 10 in a state in which a pair of side plates 21 are bonded as shown in FIG. That is, the space between the pair of side plates 21 by forming a pair of side plates 21 along the longitudinal direction of the cheolgolbo 10 on both ends of the upper flange (10a) of the cheolgolbo. As a result, the pair of side plates 21 becomes a kind of permanent formwork for forming the concrete beam 20, and the concrete is filled in the space therebetween is completed by the concrete beam 20.

콘크리트보(20)는 그 양측면을 경사지게 형성되도록 구성하면 보헌치로 형성될 수 있게 되며, 한쌍의 측면플레이트(21)를 이용하여 콘크리트보(20)를 시공하는 경우에는 한쌍의 측면플레이트(21)를 상향하여 점점 간격이 벌어지도록 경사지게 설치하는 것만으로 간편하게 보헌치를 구성할 수 있을 것이다.When the concrete beam 20 is configured to be formed to be inclined both sides, it can be formed as a booncheung, when using a pair of side plates 21 when constructing the concrete beam 20 a pair of side plates 21 By simply installing the inclined slope so that the gap is gradually upward and can be configured easily.

콘크리트보(20)와 철골보(10)의 일체화를 위해 철골보의 상부플랜지(10a) 상부면에는 스터드볼트와 같이 시어코넥터(shear connector, 22)를 접합하는 것이 바람직하겠다.In order to integrate the concrete beam 20 and the cheolgolbo 10, it is preferable to bond a shear connector 22 to the upper surface of the upper flange 10a of the cheolgolbo like a stud bolt.

철근콘크리트슬래브(30)는 상기 콘크리트보(20) 위 수평방향으로 콘크리트 보(20)와 일체화 시공된다. 콘크리트보(20)와 철근콘크리트슬래브(30)의 일체화는 콘크리트 동시타설로 구현할 수 있다. Reinforced concrete slab 30 is integrally constructed with the concrete beam 20 in the horizontal direction on the concrete beam 20. The integration of the concrete beam 20 and the reinforced concrete slab 30 can be implemented by placing concrete simultaneously.

상기와 같은 구성으로, 본 발명은 도 1과 같은 종래의 합성구조에 비해 철골보(10)의 규격이 축소되어 강재량을 감축시킬 수 있게 되는 한편, 콘크리트보(20)에 의해 압축력이 보완되므로 전체적으로 강성이 보강된 합성구조로 완성되게 된다. 실제, 도 1 합성구조에서의 철골보의 보춤과 도 2 합성구조에서의 합성보(콘크리트보+철골보)의 보춤을 동일하게 하여 전체적으로 도 1의 합성구조에 비해 도 2의 합성구조의 강재량을 10~15%물량을 줄인 상태에서 구조 계산해 본 결과, 도 1의 합성구조와 도 2의 합성구조의 강성이 거의 유사하게 나타났다. With the configuration as described above, the present invention can reduce the amount of steel by reducing the size of the steel cheolgol 10 compared to the conventional composite structure as shown in Figure 1, while the compressive force is complemented by the concrete beam 20 as a whole The stiffened composite structure is completed. Actually, the steel beam of the composite structure of FIG. 2 compared to the composite structure of FIG. 1 by equalizing the beam beam of the steel beam in the composite structure of FIG. 1 and the composite beam (concrete beam + steel ball) in the composite structure of FIG. As a result of structural calculation with 15% reduction, the stiffness of the composite structure of FIG. 1 and that of FIG.
