DOOR FRAME STRUCTURE FOR HINGED DOOR
PROBLEM TO BE SOLVED: To improve heat insulation properties of a door frame 3 for a hinged door by propagating heat of a fire slow to a non-fire-occurrence side through the door frame 3 in a case that the fire takes place.SOLUTION: A first door frame face and a second door frame face formed inside and outside across a door stop face 3a of a door frame 3 are covered by providing a sheet type foaming fire-resistant material 4 which foams on receiving heat of a fire, and surfaces of foaming fire-resistant materials 4 corresponding to the first and second door frame faces are covered with first and second surface plates 5a, 5b made of a decorative steel plate having been divided, so that the surface plate on a non-fire-occurrence side is not affected by deformation of the surface plate 5 when the foaming fire-resistant material 4 on a fire occurrence side foams.SELECTED DRAWING: Figure 2
【課題】開き戸用の戸枠３において、火災が発生した場合に、火災の熱が戸枠３を通して非火災発生側に伝達するのを遅くして遮熱性の向上を図る。【解決手段】戸枠３の戸当り面３ａを境にして形成される室内外の第一戸枠面と第二戸枠面に、火災の熱を受けて発泡するシート状の発泡性耐火材４を設けて被覆すると共に、該第一、第二戸枠面に対応する発泡性耐火材４の表面に、化粧鋼板からなる第一、第二表面板５ａ、５ｂを分割して被覆するようにして、火災発生側の発泡性耐火材４が発泡したときの表面板５の変形が、非火災発生側の表面板に影響を受けないようにする。【選択図】図２
