Description

A single open fire door with perspective structure

technical field

The utility model relates to the technical field of fire doors, in particular to a single-open fire door with a see-through structure.

Background technique

A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people.

In the existing technical solutions, general fire doors often have no perspective ability, that is, they do not know anything happening on the back of the fire door, which is not conducive to timely and accurate selection of escape routes at the fire scene. Therefore, in order to solve the above problems , on the existing fire doors, either cat's eyes are installed, or other perspective effects, such as glass, are installed. However, in the application of fire doors, this structure often results in fireproof glass and There is a gap between the fire doors, and this gap will cause flames and smoke to escape directly, which is not conducive to the escape at the scene, and the fire protection ability of the fire door depends to a large extent on the anti-combustion ability of the fire door. The outer surface of the door is often covered with metal, so it is definitely difficult to damage it by direct combustion. However, in practice, it will be found that fire doors are often burned out. Bad.
