FIREPROOF STRUCTURE OF UPPER FRAME OF SLIDING DOOR
To prevent formation of a gap in an upper frame that is detrimental to fire protection when a door body of a sliding door is in a fully closed position.SOLUTION: An upper frame 3 of a suspended sliding door is made up of an upper frame body 3' and an inspection cover 4. The inspection cover 4 includes a supported portion (upper end portions of a face 40 and horizontal piece 41) formed at the upper end of the face 40 and a plurality of rising engagement pieces 42. The upper frame body 3' includes a rising support piece 353 that contacts and supports the supported portion of the inspection cover 4, and a contacting portion 351' that the rising engagement pieces 42 contact from the inside. One or more combustible elements are provided inside the upper frame 3. The inspection cover 4, which includes a first fastening piece 42A located on the door end side of a door end-side suspension wheel unit 66 of a door body 6 in a fully closed position, a second fastening piece 42B located a door tail side of a door tail-side suspension wheel unit 66, and a third fastening piece 42C located between the door end-side suspension wheel unit 66 and the door tail-side suspension wheel unit 66, maintains the contact between the rising support piece 353 and the supported portion in the vicinity of the combustible elements.SELECTED DRAWING: Figure 1
【課題】引戸の扉体が全閉姿勢にある時に、上枠に防火上不利な隙間が形成されることを防止する。【解決手段】上吊り引戸の上枠３は上枠本体３´と点検カバー４からなり、点検カバー４は、面部４０の上端に形成された被支承部（面部４０の上端部位、水平片４１）と複数の立ち上がり係止片４２を備え、上枠本体３´は、点検カバー４の前記被支承部に当接して支承する立ち上がり支承片３５３と、立ち上がり係止片４２が内側から当接する被当接部３５１´と、を備え、上枠３内には１つ以上の可燃要素が設けてあり、点検カバー４は、全閉姿勢にある扉体６の戸先側吊車ユニット６６の戸先側に位置する第１係止片４２Ａ、戸尻側吊車６６の戸尻側に位置する第２係止片４２Ｂ、戸先側吊車ユニット６６と戸尻側吊車ユニット６６の間に位置する第３係止片４２Ｃ、を含み、前記可燃要素の近傍における立ち上がり支承片３５３と前記被支承部の当接状態を維持する。【選択図】図１
