Description

Technical Field

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fireproof partition with a certain degree of fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. It is specially used to isolate fire sources in housing buildings and plays a huge role in firefighting. Once a fire occurs, people can get a chance to escape through fire doors. However, most of the fire doors currently used have a relatively simple structure, which makes it very easy to deform and unable to open in the event of a fire, and it is also inconvenient for personnel to judge the fire situation behind the fire door.

The utility model can greatly improve the high temperature resistance, heat insulation and flame retardancy of the fire door through the mutual cooperation of the heat insulation layer 102, the flame retardant layer 103, the reinforcement layer 104 and the sound insulation layer 105, greatly enhancing the service life and safety performance of the fire door, and conveniently allowing personnel to observe the fire situation in time through the observation window 107 so as to take timely action, solving the problem that most of the currently used fire doors have a relatively simple structure, which makes them very easy to deform and unable to be opened when a fire occurs, and facilitating personnel to judge the fire situation behind the fire door.

[0023] According to one embodiment of the utility model, Figure 1-4 As shown, the outer side of the high temperature resistant door panel layer 101 is coated with anti-corrosion and fireproof coating, which can ensure the service life of the fireproof door and improve the safety performance.

[0024] According to another embodiment of the present invention, Figure 3 and Figure 4 As shown, the heat insulation layer 102 is a perlite fireproof board, which can effectively block the heat generated by the fire and prevent people on the other side of the fire door from being baked by high temperature.

[0025] The flame retardant layer 103 is a silicone flame retardant board, which has excellent high temperature resistance and corrosion resistance, and can prevent the material from burning by absorbing heat and releasing inert gas.

[0026] The reinforcement layer 104 is an asbestos board, which has high tensile strength, high flexibility, resistance to chemical and thermal corrosion, strong toughness, and good sound insulation and heat preservation effects.

[0027] According to another embodiment of the present invention, Figure 1 and Figure 2 As shown, the observation window 107 is made of hollow high-temperature resistant tempered glass. There are two observation windows 107, and the upper and lower intervals are arranged on the door panel assembly 100. The purpose of this is to facilitate the observation work of people of different heights and ages, which is more convenient. The utility model can facilitate people to observe the fire situation through the observation window 107, which is more convenient.

[0029] The use of the utility model:

[0030] First of all, it should be made clear that the fire doors involved in the present invention are mainly used in public places such as shopping malls, schools, communities, hospitals or other places that require fire protection. The present invention takes the installation and use of fire doors as an example to explain in detail the method of use. When the fire door needs to be installed, the fireproof and high-temperature resistant installation groove 108 is manually inserted into the wall, and then the high-temperature flame-retardant expansion sealant is injected into the gap between the fireproof and high-temperature resistant installation groove 108 and the wall. After it dries and solidifies, the fire door is then hingedly arranged on the outside of the fireproof and high-temperature resistant installation groove 108 through hinges (a high-temperature resistant sealing strip is arranged on the outside of the fire door), and then the installation of the fire door can be completed. When a fire occurs, outsiders can view the fire situation through the observation window 107, so as to take corresponding fire extinguishing measures in time or wait for rescue. The utility model can achieve a substantial improvement in the high temperature resistance, heat insulation and flame retardancy of the fire door through the mutual cooperation of the heat insulation layer 102, the flame retardant layer 103, the reinforcement layer 104 and the sound insulation layer 105, greatly enhancing the service life and safety performance of the fire door. The observation window 107 allows personnel to observe the fire situation in time so as to take timely action, solving the problem that most of the currently used fire doors have a relatively simple structure, which makes them very easy to deform and unable to be opened when a fire occurs, and facilitates personnel to judge the fire situation behind the fire door.
