Smoke insulation fireproof door

Abstract

The invention relates to a smoke insulation fireproof door. The smoke insulation fireproof door comprises a door frame and a door body hinged with the door frame, wherein one side of the door body isprovided with a vertically arranged fireproof edge in a protruding mode, the thickness of the fireproof edge is smaller than that of the door frame, a sink groove for the fireproof edge to enter is formed in the position, corresponding to the fireproof edge, of the door frame, and a hinge point of the door body and the door frame is arranged on the fireproof edge; the top surface, the bottom surface and the side surface, far away from the hinge point, of the door body are provided with mutually-communicated grooves, and water bags distributed along the grooves are embedded in the grooves; andwater supply pipes communicating with the water bags are embedded in the door body, and one ends, extending out of the door body, of the water supply pipes are positioned between the fireproof edge and the sink tank. By adopting the technical scheme, the water supply pipes supply water to the water bags to expand the water bags, so that the gap between the door body and the door frame is filled through the expanded water bags, the smoke insulation effect is achieved, the gap between the peripheral surface of the fireproof door and the door frame is reduced, the smoke insulation performance ofthe fireproof door is improved, and the safety of life and property of people is protected.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a smoke-proof fire door. Background technique [0002] At present, fire doors usually refer to the doors located in some closed places such as stair walkways, elevator rooms, cable wells, exhaust ducts, etc. Fire doors can meet the fire resistance stability and heat insulation within a certain period of time, and can prevent the fire from spreading and spreading. , to ensure the evacuation of personnel. [0003] In order to facilitate the opening and closing of the existing fire doors, after the fire doors are installed, a certain gap will be reserved on the upper and lower sides of the fire doors. It tends to emerge along the upper and lower gaps of the fire door. From the perspective of personal injury caused by fire, the thick smoke generated by fire is often the source of the greatest personal injury.

Problems solved by technology

[0003] In order to facilitate the opening and closing of the existing fire doors, after the fire doors are installed, a certain gap will be reserved on the upper and lower sides of the fire doors. It often emerges along the upper and lower gaps of the fire door. From the perspective of personal injury caused by fire, the thick smoke generated by the fire is often the source of the greatest personal injury.

[0004] The above existing technical solutions have the following defects: when the fire door is installed, the gap between the upper and lower sides of the fire door cannot be completely sealed, and it is not conducive to isolating dense smoke in the event of a fire, so there is room for improvement
