Zusammenfassung: | A seismic reinforcement method of an outer square door-type frame for integrating through shear connection using a gap level plate and a sleeve anchor cap can share load by allowing a new vertical column member to serve as a base plate in a seismic resistance behavior by vertically constructing the new column member so that a great vertical spacing error (Δh) is minimized when the new column member of a square door-type frame used for new reinforcement is not in close contact with a conventional vertical column to have difficulty in installation thereof or a great vertical spacing error occurs therebetween, can suppress the occurrence of local ground pressure cracking around bored anchor holes upon boring for installation of anchors, allows the anchors inserted into the bored holes to serve as a reinforcing rigid body, allows the new column of the square door-type frame to have a box-shaped cross section filled with concrete for the purpose of increasing rigidity and strength, prevents leakage of concrete poured into anchor insertion holes for installation of the anchors formed in the outer surface thereof, and allows the anchors to be coupled to the new column at anchor points.
본 발명은 신설 보강에 사용되는 사각 문형 프레임의 수직한 신설기둥부재가 기존 수직기둥에 잘 밀착되지 않아 설치 곤란하거나 이들 사이에 큰 수직이격오차(△h)가 발생할 경우, 그 수직이격 오차가 최소화되도록 수직하게 신설기둥부재가 시공되어져 내진 저항거동시 베이스판 역할로 하중을 분담할 수 있고, 앵커체 설치를 위한 천공시 천공 앵커홀 주변의 국부 지압균열 발생을 억제함과 더불어 천공홀에 삽입된 앵커체가 보강강체 기능을 갖도록 하고, 사각문형 프레임의 신설기둥은 강성과 강도를 증대할 목적으로 콘크리트 충전되는 박스단면을 갖되 외부측면에 형성된 앵커체 설치용 앵커삽입홀로 타설콘크리트의 누액을 방지하고 앵커체를 신설기둥에 고정점 결합이 되도록 한 것을 특징으로 한다. |
