Detailed Description
The utility model will be described in further detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 3, the present utility model is a high temperature resistant fire door comprising: outer frame 1, and the door leaf of being connected with outer frame 1, the door leaf includes: the door frame 2, the supporting structure 3 that sets up in door frame 2, the fire prevention glass 5 of card setting in door frame 2 front and back side to and connect respectively at door frame 2 front and back side's heat insulating board 6.
The heat insulating board 6 of this embodiment is a magnesium oxide board, which is a high temperature refractory material with magnesium oxide as a main component, has good heat insulating performance and high temperature resistance, and can be used in a high temperature environment with a temperature of up to 1800 ℃.
Specifically, the heat insulating plate 6 is connected to the door frame 2 through screws, the fireproof glass 5 is coated in the heat insulating plate 6, when a high-temperature fire disaster occurs, the heat insulating plate 6 can slow down the high-temperature transmission speed, the time and the degree of heat conduction to the door frame 2 and the fireproof glass 5 are reduced, and the structure and the stability of the door are protected, so that the fireproof effect is achieved.
Specifically, the high temperature resistant fireproof door of this embodiment through adopting bearing structure 3 and the technical scheme that sets up heat insulating board 6 in the door leaf outside, has solved the not good problem of the thermal-insulated performance of traditional fireproof door to stability and security under high temperature environment have been improved to prevent fire door.
Furthermore, the supporting structure 3 is of an X-shaped structure, so that the strength and stability of the door frame 2 can be improved, and the door frame 2 is more durable in a high-temperature environment; meanwhile, the weight of the door frame 2 can be reduced by the structure, so that the door frame 2 is easier to open and close, and the use experience is improved; in addition, the supporting mode of the X-shaped structure can reduce the space inside the door frame 2 and improve the heat insulation effect.
Further, the center point of the support structure 3 coincides with the center point of the door frame 2.
Specifically, the center point of the supporting structure 3 coincides with the center point of the door frame 2, so that the center of gravity of the door leaf coincides with the center point of the door frame 1, which is very important for the performance of the fire door, because the fire door needs to maintain the stability of the structure at high temperature and under flame to ensure that it can effectively isolate the fire source and prevent the spread of fire, and therefore, the center point of the supporting structure 3 coincides with the center point of the door frame 2, which can improve the stability and safety of the door leaf, thereby improving the performance of the fire door.
Further, the front side and the back side of the door frame 2 are respectively provided with an installation groove 21 inwards, the fireproof glass 5 is clamped in the installation grooves 21, and expansion division bars 4 are connected between the periphery of the fireproof glass 5 and the installation grooves 21.
