Fireproof roll screen with evacuating fireproof door

Abstract

The invention discloses a fireproof roll screen with an evacuating fireproof door. The fireproof roll screen with the evacuating fireproof door comprises a main door frame and an auxiliary door frame, wherein the auxiliary door frame is hinged to the bottom of a first side frame of the main door frame; a fireproof roll screen surface is mounted on the inner side of the main door frame; the evacuating fireproof door is mounted on the inner side of the auxiliary door frame; and a notch is formed in the bottom of the fireproof roll screen surface and corresponds to the position of the auxiliary door frame. When the fireproof roll screen with the evacuating fireproof door is used in the daily life, the fireproof roll screen and the evacuating fireproof door are opened completely, a door leaf of the evacuating fireproof door and the auxiliary door frame on a movable side are opened completely, and smoothness of a passage is guaranteed. When fire breaks out, the evacuating fireproof door is closed after the command of a fire control center is received, and meanwhile, the fireproof roll screen can also receive the command of the fire control center, then descends automatically and is closed. By the fireproof roll screen and the evacuating fireproof door which are used together, fire prevention requirements of the fire fighting passage are met completely, the door leaf of the evacuating fireproof door can be opened at any time according to demands of escape, and then requirements of escape are met.

Description

technical field [0001] The invention relates to a fire door, in particular to a fire shutter with an evacuation fire door. Background technique [0002] Fire prevention is a very important task in construction engineering, and fire doors are an important part of building fire prevention facilities. The design concept and use concept of modern buildings are becoming more and more efficient and intensive, which is fully reflected in each unit and product in the building. The fire shutters used in the escape routes of buildings have obvious characteristics. Existing fire shutters, due to the complete closure of escape passages when a fire occurs, require fire doors for escape to be installed near the fire shutters, resulting in waste of cost and space. Especially when it is reflected in the buildings of modern metropolises where every inch of land is expensive, this problem is even more prominent.
