Description

A double-open perspective fire door with skeleton structure

technical field

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

Among the existing fire doors, single-open fire doors are relatively rare, and double-open fire doors are more common. Although this kind of fire protection is suitable for relatively spacious passages, there are still some problems in practical applications. Many defects, such as no perspective ability, and the main defects after actual use are: firstly, the double-opening fire doors are relatively wide, and the fire doors of this structure lack the ability to keep closed, making the fire doors closed. It is not strict, and the double-opening fire doors often cause the fire doors to not be closed well because the two doors are closed at the same time. The fixation is poor, and there are certain safety hazards; Weaker, especially when it is baked by flames, it will not be able to bear its own gravity, and it will destroy the perfect structure of the fire door, causing flames and smoke to escape; Very good fire resistance.
