Anti-collision sealing fire door

Abstract

The invention provides an anti-collision sealing fire door. The anti-collision sealing fire door is particularly applicable to double-panel fire doors. Good sealing effect is achieved through a sealing device arranged at the lap joint of door panels; the sealing device is mainly made from flame-retardant organic materials, so that the sealing effect is guaranteed, the buffering effect is achieved, and better fire and theft prevention performance is realized with the characteristics of the fire door.

Description

technical field [0001] The invention belongs to the field of fire doors, in particular to a sealed anti-collision fire door. Background technique [0002] At present, the double-leaf steel fireproof doors on the market include a door frame, a left door panel and a right door panel. The door frame, left door panel and right door panel are all made of steel materials. Core. The above design can guarantee a good fire prevention effect, but this kind of double-door fireproof steel door has a large weight. When it is opened and closed in normal use, the collision between the lap joints of the door panels is serious, and the buffer is small. Not only the sound is very loud, but also the impact of noise People study normally, and the long-term severe collision of the switch will not only affect the life of the fire door, but also make the sealing of the fire door worse. In this way, in the event of a fire, flames and thick smoke will pass through this gap, which cannot prevent the...

The above design can guarantee a good fire prevention effect, but this kind of double-door fireproof steel door has a large weight. In normal use, when the door panels are opened and closed, the collision at the overlapping joints is serious, and the buffer is small. Not only the sound is very loud, but the noise is affected People study normally, and the long-term severe collision of the switch will not only affect the life of the fire door, but also make the sealing of the fire door worse. In this way, when a fire occurs, the flame and thick smoke will pass through the gap, which cannot prevent the spread of the flame.
