Description

TECHNICAL FIELD

[0002] In the field of building safety, fire doors and door frames are important fire protection facilities, and their performance is directly related to the safety of personnel and property protection. They are widely used in residential, commercial buildings, industrial plants and other types of places. With the continuous improvement of safety standards, environmental protection requirements and user experience in the construction industry, traditional fire doors and door frames have gradually exposed many performance defects and have been difficult to meet the actual needs of the current market. From the structural strength and durability, the frame of the traditional fire door is made of ordinary steel plate or composite material, and the thickness of the plate is generally less than 1mm. Some of the frame has a hollow or filled with inferior material inside, which leads to poor overall structural stability. After long-term use, it is easy to deform, crack and other problems, which not only affects the normal opening and closing of the door body, but also reduces the impact resistance of the fire door, making it difficult to maintain structural integrity in emergency situations such as fire. At the same time, the traditional door plate is mostly single or simple double-layer structure, lacking effective support and reinforcement design, which is easy to damage when subjected to external impact, and has a short service life.
