Description

구조물의 개구부 내진보강장치 및 이를 이용한 내진보강공법Seismic reinforcement device for opening of structure and seismic reinforcement method using the same
본 발명은 구조물의 개구부 내진보강장치 및 이를 이용한 내진보강공법에 관한 것으로, 더 상세하게는 다수의 창호, 문틀 등의 설치를 위한 개구부의 형성으로 인해 내진성이 떨어지는 것을 방지할 수 있는 구조물의 개구부 내진보강장치 및 이를 이용한 내진보강공법에 관한 것이다. The present invention relates to an earthquake-resistant reinforcing device of the structure and a seismic reinforcing method using the same, and more particularly, the seismic opening of the structure that can prevent the fall of the earthquake resistance due to the formation of openings for the installation of a plurality of windows, door frames, etc. It relates to a reinforcement device and a seismic reinforcement method using the same.
일반적으로 건축구조물 또는 토목구조물에는 창문(창호), 출입문, 부대시설등을 설치하기 위한 개구부가 설치된다. 이러한 개구부에는 일정 크기 이상의 개구공간(void space)을 확보한 후, 개구공간 내측면에 창호, 알루미늄 샤시, 부대시설구조물 등을 삽입하여 고정하는 것이 보통이다. In general, architectural structures or civil engineering structures are provided with openings for installing windows (windows), doors, and auxiliary facilities. It is common to secure a void space of a predetermined size or more in such an opening, and then insert and fix a window, an aluminum chassis, an auxiliary structure, etc. on the inner surface of the aperture space.
이러한 개구부는 콘크리트 건물, 조적식 건물을 비롯한 다양한 건축구조물에서 다른 부분에 비해 응력 집중이 심한 것으로 알려져 있다. 특히, 지진, 태풍 등의 발생으로 인해 진동이 발생하는 경우, 건축구조물의 개구부로부터 인장균열의 발생되기 때문에 개구부가 많은 건물은 지진이나 강풍에 매우 취약한 것으로 알려져 있다. These openings are known to have higher stress concentrations than other parts in various building structures including concrete buildings and masonry buildings. In particular, when vibration occurs due to an earthquake or typhoon, a tensile crack is generated from an opening of a building structure, and a building having many openings is known to be very vulnerable to an earthquake or strong wind.
내진설계가 반영되지 않은 콘크리트 건물의 경우, 내진성능이 충분치 못하여 개구부에서 기인하는 구조손상으로 인해 지진 발생 시 큰 피해가 발생할 수 있음이 확인된 바 있다. In the case of concrete buildings that do not reflect the seismic design, it has been confirmed that the seismic performance may not be sufficient, resulting in significant damage in case of an earthquake due to structural damage caused by the opening.
이러한 지진으로부터 인적 피해 및 물적 피해를 최소화하기 위해 건물의 개구부 또는 기둥이나 보와 같은 구조부재에는 다양한 제진장치가 설치된다. 제진 장치를 이용한 내진보강공법은 현재 건물구조물의 신축공사 및 리 모델링 공사에 일반적으로 활용되고 있다. 예컨대 상기 제진장치는 구조부재인 프레임에 대각 방향의 가새형 댐퍼를 설치하여, 지진에 의한 반복하중 동안 소성이력거동에 의해 에너지를 소산시킴으로써 건물 손상을 최소화하게 된다. In order to minimize human and physical damage from such an earthquake, various vibration suppressors are installed in the structural members such as openings or columns or beams of buildings. Seismic reinforcement method using vibration damping device is generally used in new construction and remodeling of building structures. For example, the vibration damping device is provided with a brace-type damper in a diagonal direction in a frame that is a structural member, thereby minimizing building damage by dissipating energy by plastic hysteresis behavior during repeated loads caused by earthquakes.
그러나 이러한 일반적인 제진장치는 댐퍼를 설치하기 위해 기둥이나 보와 같은 큰 강성을 갖는 구조부재(댐퍼 지지용)를 필요로 하므로, 시공이 까다로울 뿐만 아니라, 별도의 설치공간을 확보하여야 하는 문제점이 있다. 또한 철근콘크리트 건물은 댐퍼를 위한 별도의 설치공간을 확보하기 힘들기 때문에 제진장치의 설치가 힘들고, 특히 내진성능이 취약한 저층건물에는 적합하지 않다는 문제점이 있다.  However, such a general vibration damping device requires a structural member (for damper support) having a large rigidity such as a column or a beam in order to install a damper, which is not only difficult to construct, but also requires a separate installation space. In addition, the reinforced concrete building is difficult to secure a separate installation space for the damper, it is difficult to install the vibration damping device, in particular, there is a problem that is not suitable for low-rise buildings with poor seismic performance.
이러한 점을 감안하여 대한민국 특허등록 제 0348577호에는 건물의 개구부에 설치된 수평보형 댐퍼를 이용한 내진보강공법이 게시되어 있다. In view of this, Korean Patent Registration No. 0348577 discloses a seismic reinforcing method using a horizontal beam damper installed in an opening of a building.
게시된 내진보강공법은 보의 중앙부 저면에 중앙지구를 고정시켜 지진하중에 의한 보의 휨 변형이 중앙 T형지그에 전달되도록 하고, 상기 기둥부 내측면에 댐퍼프레임을 설치하고, 상기 중앙 T형지그와 댐퍼프레임 사이에 수평보형 댐퍼를 설치하되 상기 수평보형 댐퍼가 개구부의 상부에 위치하도록 하는 단계를 포함한다. Published seismic reinforcement method is to fix the central earth to the bottom of the center of the beam so that the bending deformation of the beam due to the earthquake load is transmitted to the center T-shaped jig, the damper frame is installed on the inner side of the column, the center T-shaped And installing a horizontal beam damper between the jig and the damper frame such that the horizontal beam damper is positioned above the opening.
대한민국 특허등록 제 1161785호에는 내진성능을 가진 일체형 창호 시스템에 게시되어 있다. 게시된 기술적 구성은 개구된 공간의 일부를 브레이스와 댐퍼가 가리게 되는 문제점이 있으며, 충분한 지진에 대해 댐핑력의 확보가 어렵다. Korean Patent Registration No. 1161785 is posted on an integrated window system with seismic performance. The technical configuration disclosed has a problem that the brace and the damper cover a part of the open space, and it is difficult to secure the damping force against a sufficient earthquake.
대한민국 특허등록 제 1165320호에는 철근콘트리트 건물의 개구부 내진보강방법이 게시되어 있다. 게시된 내진보강방법은 개구부의 철골프레임에 설치되는 댐퍼를 이용하지 않고 지진에 의한 수평력을 철근콘크리트 하부벽체에 매립된 철골프레임으로 저항하도록 하게 된다. Republic of Korea Patent Registration No. 1165320 discloses the seismic reinforcement method of the opening of the reinforced concrete building. The seismic reinforcement method disclosed is to resist the horizontal force caused by the earthquake to the steel frame frame embedded in the reinforced concrete lower wall without using a damper installed in the steel frame of the opening.
게시된 내진보강방법은 철근 콘크리트의 하부벽체에 매립된 철골플레임은 모서리 보강재를 더 구비하여 단순히 구조적 강도를 보완한 것으로, 건물의 설계에 따른 비용증가의 원인이 되며, 모서리 보강재가 설치되어 있으므로 이에 의해 건물의 개구부가 잠식되는 문제점이 있다. The posted seismic reinforcement method is that the steel frame embedded in the lower wall of reinforced concrete simply supplements the structural strength by further providing the edge reinforcement, which causes the increase in cost according to the design of the building. There is a problem that the opening of the building is encroached.
