ELECTRICALLY-DRIVEN FIREPROOF DOOR DEVICE
To open and close heavy a fireproof door stably over a long period of time.SOLUTION: A fireproof door device is configured such that a rail bar 2, which causes a suspended sliding-door type fireproof door 1 to travel by wheels 12 on a carrier 11, is connected to a fixing bar 3 fixed to a building in a detachable manner and a control circuit controls a linear motor 6 to cause the carrier 11 to travel along the rail bar 2. The fireproof door device includes an engagement mechanism that connects the rear end of the rail bar 2 to the fixed bar 3 in a detachable manner, and a tilt angle adjustment mechanism 5 that adjusts the tilt angle of the rail bar 2, which is arranged in a downward slope from the rear end to the tip. The fixing bar 3 has a fixing rib 32 on the side edge of a vertical plate 21, the engagement mechanism has a holding arm for holding the rear end part of the rail bar 2 between it and the vertical plate and connecting it so as to be freely pulled out, the rear end part of the rail bar 2 placed on the fixing rib 32 is connected to the fixing bar 3 by the holding arm, and the vertical position of the end part on the door tip side is adjusted by the tilt angle adjustment mechanism 5.SELECTED DRAWING: Figure 5
【課題】重い防火ドアを長期間にわたって安定して開閉する。【解決手段】防火ドア装置は、引戸の防火ドア１を吊り下げ構造で走行台１１の車輪１２で走行させるレールバー２を、建物に固定してなる固定バー３に脱着構造で連結しており、リニアモータ６を制御回路で制御して走行台１１をレールバー２に沿って移動させる。防火ドア装置は、レールバー２の後端を固定バー３に脱着自在に連結してなる係止機構と、後端から先端に向かって下り勾配に配置してなるレールバー２の傾斜角を調整する傾斜角調整機構５とを備える。固定バー３は、垂直プレート２１の側縁に固定リブ３２を有し、係止機構は、レールバー２の後端部を垂直プレートとの間に挟んで引き抜き自在に連結する挟持アームを有し、固定リブ３２に載せたレールバー２の後端部を挟持アームで固定バー３に連結し、傾斜角調整機構５で戸先側の端部の上下位置を調整している。【選択図】図５
