Analysis of the causes of problems encountered in the use of fire doors

The function of a pair of fire doors is unclear. Fire doors mainly refer to doors that can meet fire resistance stability integrity and thermal insulation requirements within a certain period of time. It is a fire-resistant partition with a certain degree of fire resistance that is installed at the evacuation stairwell, vertical duct well inspection port, etc. in the fire-proof partition. It plays a very important role in preventing the spread of fire and smoke within a certain period of time and ensuring the safe evacuation of personnel. . However, in actual design and use work, whether it is designers or users, some personnel have vague ideas about these important functions, do not understand them clearly, do not pay enough attention, and even do not know the significance of the settings.
The coordination between the two professional designers is insufficient. In the design of building normally open fire doors, two majors generally need to work closely together to complete the project. One is a construction major and the other is an electrical major. First, the architectural major will carry out the layout and installation design of the normally open fire door in accordance with the national standards "Code for Fire Protection Design of Buildings" or "Code for Design of Fire Protection for High-Rise Civil Buildings", and then the electrical major will design the self-closing function. However, this is not the case. During the design of this project, these two majors were often out of touch and lacked coordination. In the layout design drawing of the normally open fire door of the building, only the position and some basic instructions of the normally open fire door are indicated. There is no detailed explanation of the self-closing function, and there is no timely ventilation with the electrical professional, and the electrical design The personnel also did not carefully analyze the building functions, resulting in the critical issue of normally open fire door design being ignored. This is the main reason
The manufacturer of the three fire door self-closing products does not have enough publicity. Han Yu in the Tang Dynasty had a famous saying: A thousand-mile horse always exists, but a bole does not always exist. For leading knowledge and advanced technology to be understood and mastered by the world, there should be a publicity process. In the promotion of fire protection products, fire door manufacturers often focus on products with large market demand, such as commonly used steel and wooden fire door closers, and do not highlight the self-closing products of fire doors that are not used in large quantities. Therefore, the majority of construction engineering design personnel and users in the society do not have a relatively comprehensive understanding and understanding of this, resulting in it not being widely used in design practice.
The knowledge of four pairs of normally open fire doors is insufficient. Compared with other fire doors, normally open fire doors have a self-closing function added during production. Its function is mainly realized by electromagnetic release valve or magnetic door closer and automatic control system. In the design of normally open fire doors in daily buildings, because the manufacturers of automatic control system equipment are out of touch with the manufacturers of fire doors, and the manufacturers of automatic control system equipment do not produce self-closing products for normally open fire doors, there is no fire protection in their product samples. The automatic door control method makes it difficult for designers to master and understand this expertise. Then there is the misunderstanding of the design of normally open fire doors. It is believed that normally open means that ordinary fire doors are often opened during use. Therefore, it is only designed as an ordinary fire door
