Description

Technical Field

[0001] This utility model relates to the field of fireproof doors, and in particular to a ceramic fiber heat-insulating fireproof door with high fire resistance. Background Technology

[0002] Doors are an indispensable and important part of building decoration. As door technology continues to improve, more functional building doors are appearing in our field of vision. Among them, fire doors are welcomed in scenarios where fire protection is required.

[0003] Chinese patent application number CN201020573741.6 provides a heat-insulating fireproof door. The fireproof expansion seal is internally covered with a fireproof expansion body, and the flame-retardant decorative covering material of the fireproof expansion seal is provided with raised positioning decorative lines and an elastic body is attached between the raised positioning decorative lines. It has high fire safety performance, is energy-saving and environmentally friendly, easy to implement and low cost.

[0004] Existing deep-hole laser repair methods have certain drawbacks. First, most existing fire doors are filled with ordinary heat insulation materials, which, although having a certain fire resistance, have insufficient heat insulation performance in high-temperature environments. This can easily lead to a rapid rise in the surface temperature of the door, reducing its fire resistance and heat insulation performance. Furthermore, the fire warning effect is also poor, resulting in a decrease in the safety protection effect of the fire door. Therefore, we propose a high fire resistance ceramic fiber heat insulation fire door. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a high-fire-resistant ceramic fiber insulated fire door. By setting a ceramic fiber insulation layer and an alarm, the fire door has a ceramic fiber insulation layer inside. The ceramic fiber insulation layer is composed of ceramic fiber cotton and ceramic fiber felt arranged in layers and staggered, achieving a layered combination. The ceramic fiber cotton and ceramic fiber felt are close to the fire source side, forming a gradient insulation barrier. The low thermal conductivity of this structure can delay heat conduction. Furthermore, when the fire door is in use, the smoke detector and temperature sensor can sense the smoke and temperature environment around the door in real time. When the set value is exceeded, the alarm will sound an alarm, thus improving the fire protection effect and safety performance of the insulated fire door.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A highly fire-resistant ceramic fiber insulated fire door includes a door frame body and a fire door body;

[0008] The fireproof door body includes an outer steel plate and an inner steel plate. The inner end of the outer steel plate is provided with a ceramic fiber heat insulation layer. The ceramic fiber heat insulation layer is made of ceramic fiber cotton and ceramic fiber felt arranged in layers. A smoke detector is fixedly connected to the outer end of the door frame body. A temperature sensor is movably connected to the outer side of the smoke detector. An alarm is movably connected to the outer side of the temperature sensor. The alarm is located at the outer end of the door frame body.

[0009] By installing a ceramic fiber insulation layer and an alarm, the fire resistance of the insulated fire door can be improved, while its safety performance can also be enhanced.

[0010] Furthermore, a backup power supply is fixedly connected to the rear end of the door frame body.

[0011] The installation of a backup power supply further enhances the protective effect of the fire door.

[0012] Furthermore, a fire-resistant layer is provided at the outer end of the ceramic fiber insulation layer, the fire-resistant layer is symmetrically distributed, and the fire-resistant layer is located at the inner end of the outer steel plate and the inner steel plate.

[0013] By installing a fire-resistant layer, heat can be prevented from passing through, further improving the heat resistance of the fire door.

[0014] Furthermore, an expansion sealing strip is fixedly connected to the outer end of the fire door body, and the expansion sealing strip is symmetrically distributed on the outer end of the fire door body.

[0015] The fire door's protective effect was improved by installing an expansion sealing strip.

[0016] Furthermore, a heat-insulating smoke baffle is fixedly connected to the bottom end of the fire door.

[0017] The overall protective effect of fire doors can be improved by installing heat-insulating smoke baffles.

[0018] Furthermore, a controller is fixedly connected to the outer end of the door frame body.

[0019] By installing a controller, communication between the various sensing components of the fire door can be made more convenient, and control can be made more easy.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By setting a ceramic fiber insulation layer and an alarm, the fire door has a ceramic fiber insulation layer inside. The ceramic fiber insulation layer is composed of ceramic fiber cotton and ceramic fiber felt arranged in layers and staggered in a layered combination. The ceramic fiber cotton and ceramic fiber felt are close to the fire source side to form a gradient insulation barrier. The low thermal conductivity of this structure can delay heat conduction. When the fire door is in use, the smoke detector and temperature sensor can sense the smoke and temperature environment around the door in real time. When the set value is exceeded, the alarm will sound an alarm, which improves the fire protection effect of the fire door and the safety protection performance.

[0022] 2. By setting an expansion sealing strip, which is made of an outer shell of high-temperature resistant rubber or weather-resistant PVC and an inner filling of expanded graphite material, the expansion sealing strip is set at the contact gap between the door frame body and the fire door body. When exposed to high temperature, the volume expands rapidly and automatically seals the gap, preventing the spread of flames and smoke, thus improving the protective effect of the fire door.

[0034] Reference Figure 3-4 As shown, a fire-resistant layer 9 is further provided at the outer end of the ceramic fiber insulation layer 8. The fire-resistant layer 9 is symmetrically distributed and is located at the inner end of the outer steel plate 71 and the inner steel plate 72.

[0035] The fire door body 7 is equipped with a ceramic fiber insulation layer 8 inside. The ceramic fiber insulation layer 8 is composed of ceramic fiber cotton 81 and ceramic fiber felt 82 arranged in layers and staggered, achieving a layered combination. The ceramic fiber cotton 81 and ceramic fiber felt 82 are close to the fire source side, forming a gradient heat insulation barrier. The low thermal conductivity of this structure can delay heat conduction. When the fire door is in use, the smoke detector 3 and temperature sensor 4 can sense the smoke and temperature environment around the door in real time. When the set value is exceeded, the alarm 5 will sound an alarm. The backup power supply 6 provides power to the smoke detector 3, temperature sensor 4 and alarm 5, ensuring that each component can still work in the event of a power outage or malfunction. The fire-resistant layer 9 is made of inorganic fire-resistant board material. The symmetrically distributed fire-resistant layer 9 can prevent heat from passing through, further improving the heat resistance of the fire door.

[0038] Reference Figure 1 As shown, a controller 2 is further fixedly connected to the outer end of the door frame body 1.

[0039] The expansion sealing strip 10 is made by installing an outer shell of high-temperature resistant rubber or weather-resistant PVC and an inner filling of expanded graphite material. The expansion sealing strip 10 is set at the contact gap between the door frame body 1 and the fire door body 7. When exposed to high temperature, it expands rapidly and automatically seals the gap to prevent the spread of flames and smoke. The heat insulation and smoke baffle 11 can form a protective structure at the bottom of the fire door body 7 to prevent the penetration of high-temperature smoke. The controller 2 serves as the central hub between the smoke detector 3 and other sensing components and the alarm 5 and the building management system or fire control center, making communication between the various sensing components of the fire door more convenient and control more convenient.

[0040] Specific implementation process: When the fire door is in use, the smoke detector 3 and temperature sensor 4 can sense the smoke and temperature environment around the door in real time. When the set value is exceeded, the control system controls the alarm 5 to issue an audible alarm, thereby improving the fire safety of the insulated fire door. When the fire door body 7 is in use, the fire-resistant layer 9 is made of inorganic fire-resistant board material. The symmetrically distributed fire-resistant layer 9 can prevent heat from passing through. The ceramic fiber insulation layer 8 is composed of ceramic fiber cotton 81 and ceramic fiber felt 82 arranged in layers and staggered, achieving layered combination. The ceramic fiber cotton 81 and ceramic fiber felt 82 are close to the fire source side, forming a gradient heat insulation barrier. The low thermal conductivity of this structure can delay heat conduction. The expansion sealing strip 10 is made of an outer shell of high-temperature resistant rubber or weather-resistant PVC and an inner filling of expanded graphite material. The expansion sealing strip 10 is set at the contact gap between the door frame body 1 and the fire door body 7. When exposed to high temperature, the volume expands rapidly, automatically sealing the gap and preventing the spread of flames and smoke, making the fire door safer to use.
