Description

Technical Field

[0001] The utility model relates to the technical field of safety fire doors, in particular to a building safety fire door. Background Art

[0002] Building safety fire doors refer to special doors used in buildings to prevent the spread of fire and protect the lives and property of people. They are usually made of high temperature resistant, heat-insulating and smoke-proof materials, have fire resistance, and can effectively isolate the spread of flames, smoke and heat when a fire occurs, thereby buying precious time for the evacuation of personnel. These doors are usually closed, but in the event of a fire alarm or emergency, they can be quickly opened to provide a channel for the evacuation of personnel. In addition to fire resistance, they also need to have a strong structure, safe and reliable characteristics to ensure that they remain stable in a fire and do not hinder evacuation. Building safety fire doors are a vital part of the building's fire protection system and play a key role in improving the overall fire safety of the building.

[0003] At present, in order to ensure the strength of the door panel structure of existing fire doors, steel frames must be used as support. These steel frames undergo multiple complex processes during the production process, such as stamping, cold bending and machining at high temperatures. After production, size calibration is also required to ensure the interchangeability of different door panels. These processes greatly increase the production cost of fire doors. In addition, the steel frame also increases the difficulty of assembling fire doors. During the installation process, the steel frame and other components must be accurately connected and the gap must be adjusted, otherwise the pressure-bearing performance of the fire door will be affected. These problems increase the workload of fire door assembly, making the entire process more complicated and time-consuming.

[0004] Therefore, a new building safety fire door structure is needed now, which can remove the steel frame and replace it with other high temperature resistant materials under the premise of ensuring structural strength, so as to ensure strength, simplify the production process, improve the efficiency of production and assembly, and reduce costs. Based on this, we propose a building safety fire door. Utility Model Content
