FIRE DOOR
To improve fire resistance and productivity of right and left door end stiles to be butted with each other when adopting a concave-convex fit structure in a joint part of a draw type fire door.SOLUTION: In a draw type fire door 1, a first door end side stile 21 and a second door end side stile 31 are made of stile members 2e of the same shape provided with vertically elongated recessed grooves 22 and 32 on opposing surfaces of door ends. A projecting member 40 projected from the recessed groove 22 of the first door end stile 21 toward the door end side of a first door body 20 is attached to the recessed groove 22 of the first door end stile 21, and when the door ends of the first door body 20 and a second door body 30 are butted against each other, the projecting member 40 enters into the recessed groove 32 of the second door side stile 31.SELECTED DRAWING: Figure 4
【課題】引き分け式の防火戸の付け合わせ部に凹凸構造を採用するにあたり、突き合わされる左右の戸先框の耐火性・生産性を向上させる。【解決手段】引き分け式の防火戸１において、第一戸先側框２１及び第二戸先側框３１を、上下方向に長尺な凹溝２２、３２を戸先同士の対向面に備えた同形状の框部材２ｅからなるものとし、第一戸先側框２１の凹溝２２には、第一戸体２０の戸先側に向けて第一戸先框２１の凹溝２２から突出した凸部材４０が取り付けられたものとし、第一戸体２０と第二戸体３０との戸先同士が突き合わされた際に、凸部材４０が第二戸先側框３１の凹溝３２内に入り込むよう構成した。【選択図】図４
