To improve the strength of a renovated fitting together with suppressing the spread of fire from a gap generated between an inner cover covering the indoor side part of a newly provided lower frame and a skeleton opening with the result of improving fire prevention performance.SOLUTION: A renovated fitting includes a new lower frame attached to an existing frame remaining in a skeleton opening part, and an inner cover for covering the indoor side of the new lower frame. The inner cover is engaged with an indoor side wall part of the new lower frame and fixed to the skeleton opening part on the indoor side of the new lower frame, and the new lower frame is provided with a heating expansion material expanding toward a gap between the new lower frame and the skeleton opening part upon receipt of heat on the indoor side surface of the indoor side wall.SELECTED DRAWING: Figure 3
【課題】改修建具の強度を向上するとともに、新設下枠の室内側部を覆う内部カバーと躯体開口部との間に生じる間隙からの延焼を抑制し、防火性能を向上させる。【解決手段】躯体開口部に残存する既設枠に装着される新設下枠と、新設下枠の室内側を覆う内部カバーを備え、内部カバーは、新設下枠の室内側壁部に係合されているとともに、新設下枠の室内側の躯体開口部に固定されており、新設下枠は、室内側壁の室内側面に、加熱により新設下枠と躯体開口部の間の間隙に向かって膨張する加熱膨張材が配置されている。【選択図】 図３
