본 발명은 강관이 삽입된 H형 강보에 관한 것으로서, 보다 상세하게는 H형 강보의 일단에 다수개의 강관을 삽입함으로서, 고가의 복잡한 제진장치를 사용하지 않고도, 지진 및 풍에 의해 건축 구조물에 가해지는 하중을 수평으로 분산시켜 충 격을 효율적으로 완화시켜 저렴한 비용으로 건축 구조물의 구조적 안전성을 확보할 수 있도록 한 강관이 삽입된 H형 강보에 관한 것이다.The present invention relates to an H type steel beam in which a steel pipe is inserted, and more particularly, by inserting a plurality of steel pipes into one end of the H type steel beam, it is applied to a building structure by earthquakes and winds without using an expensive and complicated vibration damping device. It is related to the H-beam with the steel pipe inserted to distribute the load horizontally to efficiently alleviate the impact and secure structural safety of the building structure at low cost.

일반적으로, 도심의 빌딩, 고층복합시설 등과 같은 건축물을 시공하는 경우 탑/다운(Top/down) 공법 또는 다운워드(Downward) 공법을 많이 적용한다.In general, when constructing a building such as a city center building, a high-rise complex, etc., a top / down method or a downward method are frequently applied.

탑/다운 공법이란, 지상층과 지하층을 동시에 시공하는 공법으로서, 지상층의 경우 골격을 세워 가면서 그대로 진행하고, 이와 동시에 지하층의 경우 골격을 세운 후, 한층씩 파내려가면서 시공을 하는 공법이며, 다운워드(Downward) 공법은 탑/다운 공법과는 달리 지하층 부분만 역 타시공하는 공법으로, 도 1 및 도 2에 도시된 바와 같이, 상기 두 공법 모두 각 건축 구조물의 시공을 위한 기둥(P)의 콘크리트 타설작업 전, H형 강보(10)를 각 기둥(P)사이를 연결하며 설치하여 견고한 건축 구조물을 시공할 수 있도록 한다.The top / down method is a method of constructing the ground floor and the basement at the same time, and proceeds as it is while building the skeleton in the ground floor, and at the same time, after constructing the skeleton in the basement floor, the construction is carried out by digging one by one. Unlike the top / down method, a downward method is a method for reverse construction of only a basement part, as shown in FIGS. 1 and 2, in which both methods are concrete of a pillar (P) for construction of each building structure. Before pouring work, install H-shaped steel beams 10 between each pillar P to install a solid building structure.

하지만, 상기와 같은 종래의 H형 강보는 제진요소, 즉, 지진 및 풍에 의해 건축 구조물에 가해지는 하중을 수평으로 분산시켜 충격을 완화시킬 수 있는 요소가 미비하여 상기 건축 구조물이 지진 및 풍에 의한 하중에 견디지 못하게 되는 문제점이 있었다.However, the conventional H-shaped steel as described above is a vibration damping element, that is, elements that can mitigate the impact by horizontally distributing the load applied to the building structure by the earthquake and wind is insufficient, so that the building structure to earthquake and wind There was a problem that can not stand the load.

상기와 같은 문제점을 해결하기 위하여, 오일 댐퍼 등의 장치를 다수개의 각 H형 강보 사이에 설치하여, 상기 지진 및 풍에 의한 하중을 견딜 수 있게 설계하고 있는 실정이나, 상기의 오일 댐퍼 등은 고가의 복잡한 장치로서, 건축 구조물의 구조적 안전성을 확보하는데 많은 비용이 소요되는 등의 문제점이 있었다.In order to solve the above problems, a device such as an oil damper is installed between a plurality of H-shaped steel beams and designed to withstand the load caused by the earthquake and wind, but the oil damper is expensive. As a complex device, there is a problem such as a high cost to ensure the structural safety of the building structure.
