FIRE DOOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a fire door structure that improves flame interruption performance in addition to heat shielding performance.SOLUTION: A fire door structure includes: a fire door 12 that has a cavity part 10; an opening part 18 that is formed in a header part 26 of the fire door 12 and that communicates with the cavity part 10; and a refractory material 20 which is provided in the cavity part 10, which is thermally expanded in case of fire to fill the inside of the cavity part 10, and which leaks out from the opening 18 to close a gap dU between the fire door 12 and a door frame 14 fitted with the fire door 12.
【課題】遮熱性能に加えて、遮炎性能を高めた防火戸構造を提供する。【解決手段】防火戸構造は、空洞部１０を有する防火戸１２と、防火戸１２の小口部２６に形成され、空洞部１０と連通する開口部１８と、空洞部１０に設けられ、火災時に熱膨張して空洞部１０の内部を充満させ、開口部１８から漏れ出て、防火戸１２と防火戸１２が取付けられた戸枠１４との隙間ｄＵを塞ぐ耐火材２０と、を有している。【選択図】図２
