FIRE PROTECTION REFURBISHMENT SASH
PROBLEM TO BE SOLVED: To provide a fire protection refurbishment sash capable of efficiently blocking a gap between an existing frame body and a new frame body to swiftly and reliably prevent communication between the outdoor and the indoor at a fire.SOLUTION: The fire protection refurbishment sash includes: a new frame body which is fixed to an existing frame body installed in an opening of a building; and a thermal expansion material that blocks a gap between the existing frame body and the new frame body being inflated by the heat. The thermal expansion material is disposed between the existing frame body and the new frame body (being attached to the new frame body), adjacent to the end at the indoor side and the end at the outdoor side in a depth direction. In the end at the indoor side and/or the end at the outdoor side where the thermal expansion material is disposed, the new frame body and the existing frame body are positioned close to each other.SELECTED DRAWING: Figure 3
【課題】火災時に既設の枠体と新設の枠体との間を効率的に塞ぐことができ、室内外の連通を素早く確実に防止することができる防火改装サッシを提供する。【解決手段】建物開口部に設置されている既設枠体に対して固定される新設枠体と、加熱により膨張して既設枠体と新設枠体の間の間隙を閉塞する加熱膨張材とを備え、加熱膨張材は、見込み方向の室内側端部近傍及び室外側端部近傍において既設枠体と新設枠体との間に（おいて新設枠体に）配置されており、加熱膨張材が配置される室内側端部近傍及び／又は室外側端部近傍において、新設枠体と既設枠体とが近接している。【選択図】図３
