Description

Can block fire door of smog

Technical Field

The invention belongs to the technical field of fireproof doors, and particularly relates to a fireproof door capable of blocking smoke.

Background

The fireproof door is a door which can meet the requirements of fire-resistant stability, integrity and heat insulation within a certain time, and is a fireproof partition which is arranged between fireproof partitions, evacuation staircases, vertical shafts and the like and has certain fire resistance. The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people.

In order to facilitate the rotation of the door panel, a certain gap is reserved between the door panel and the ground, so that the friction between the door panel and the ground is avoided, but the reserved gap is also the gap, so that the sealing effect of the fireproof door is reduced, and partial smoke can pass through the gap between the door panel and the ground when a fire disaster happens; meanwhile, in order to solve the defect, a complete rectangular door frame is adopted for some fire-proof doors, namely, a frame at the lower side of the door frame is arranged on the ground, and when the fire-proof door is closed, the frame is in sealing contact with the lower side of the door plate, but the design causes inconvenience when people pass through the fire-proof door every day, and the situation of stumbling is easy to occur; meanwhile, after the fireproof door is closed, people cannot directly observe the situation on the other side of the fireproof door, and further cannot accurately judge the fire on the other side of the fireproof door in time, so that people can easily make an incorrect evacuation strategy; if the fire judged by people is larger than the actual fire, people can be in an overstrained state, but mistakes are easy to make mistakes in a hurry, and if the fire judged by people is smaller than the actual fire, people are easy to make a lacked response, and the best evacuation escape practice is delayed.
