Folding fireproof door
The invention discloses a folding fireproof door. Comprising a door frame fixed in a door opening, a primary door rotationally installed on the door frame through hinges, a secondary door rotationally connected with the primary door through hinges, a double-shaft door closer fixedly installed on the upper portion of the primary door, and a primary door connecting rod mechanism with one end fixedly connected with a first transmission shaft of the double-shaft door closer and the other end rotationally connected with the door frame on the top of the primary door. One end of the secondary door connecting rod mechanism is fixedly connected with a second transmission shaft of the double-shaft door closer, and the other end of the secondary door connecting rod mechanism is rotationally connected with the secondary door; the first transmission shaft and the second transmission shaft are linked with each other and are opposite in rotating direction, so that the secondary door can be completely opened and folded on the back surface of the primary door while the primary door is completely opened. The device can be widely applied to upgrading and reconstruction of fireproof doors in various occasions, on the premise of meeting normal fire protection requirements, rapid and synchronous opening of the secondary door and the primary door can be achieved, the effective clear width of an evacuation channel is guaranteed, occupation of other channels after the fireproof door is opened outwards is reduced, and the device is safe, reliable and low in production cost.
本发明公开了一种折叠防火门，包括固定在门洞内的门框、通过合页转动安装在门框上的母门、通过合页与母门转动相连的子门、固定安装在母门上部的双轴闭门器、一端与双轴闭门器的第一传动轴固定相连另一端与母门顶部门框转动相连的母门连杆机构、以及一端与双轴闭门器的第二传动轴固定相连另一端与所述子门转动相连的子门连杆机构；第一传动轴和第二传动轴相互联动，转向相反，使母门被完全打开的同时子门也能被完全打开并折叠于母门背面。本发明可广泛应用于各种场合防火门的升级改造，在满足正常消防要求的前提下，能够实现子门和母门的快速同步开启，既保证了疏散通道的有效净宽，又减少防火门外开后对其他通道的占用，安全可靠，生产成本低。
