Fig. 2 is a schematic structural view of a second embodiment of a fire-proof elevator door according to the present invention.
Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 to 2 are schematic structural views of a fireproof elevator door according to the present invention. The utility model provides a fire prevention lift-cabin door, includes inside hollow lift-cabin door body 10, glass magnesium board 20 and steel sheet 30, glass magnesium board 20 is located in lift-cabin door body 10 and with lift-cabin door body 10 cooperatees, glass magnesium board 20 one side is passed through aerogel 40 and is bonded on the surface of the inside front side of lift-cabin door body 10, steel sheet 30 is located in lift-cabin door body 10 and with lift-cabin door body 10 cooperatees, steel sheet 30 one side sets up on the surface of the other side of glass magnesium board 20, steel sheet 30 opposite side not with the surface contact of the inside rear side of lift-cabin door body 10.
After the left sides or the right sides of the two elevator door bodies 10 are assembled with the elevator room, the rear sides of the elevator door bodies 10 face the outside of the elevator room, and the front sides of the elevator door bodies 10 face the inside of the elevator room;
if people are trapped in the elevator room and a fire disaster occurs outside the elevator room, the people cannot escape from the elevator room and the fire disaster site and only stay in the elevator room to wait for rescue, and the two elevator door bodies 10 are important channels for connecting the elevator room and the elevator room;
in the process that the fireproof elevator door is heated by fire, the glass magnesium board 20 can absorb a large amount of heat energy, delay the temperature rise of the fireproof elevator door and further delay the temperature rise in the elevator room, so that the safety of personnel in the elevator room is guaranteed, and valuable time is won for rescue workers; the glass magnesium board 20 is a non-combustible material and has the advantages of good fireproof performance, no combustion when the flame is continuously burnt for 0,800 ℃, no flame at 1200 ℃ and the like;
after the glass magnesium board 20 absorbs a large amount of heat energy, the two ends of the glass magnesium board 20 can bend towards the direction with high heat energy, so that the glass magnesium board 20 can not be completely attached to the front side surface in the elevator door body 10, the effect of absorbing the heat energy is greatly reduced, the temperature in the elevator room rises again, through the arrangement of the steel plate 30, the steel plate 30 is attached to and tightly presses the surface of the glass magnesium board 20, the bending of the two ends of the glass magnesium board 20 towards the direction with high heat energy is limited, the fireproof performance of the glass magnesium board 20 is further improved, the safety of personnel in the elevator room is greatly increased, and the safety of the personnel in the elevator room is improved.
In the first embodiment, the elevator door body 10 prevents both ends of the magnesium oxide sheet 20 from being bent in a direction of high heat energy, and the steel sheet 30 presses the middle of the magnesium oxide sheet 20.
In the second embodiment, the steel plate 30 does not bend the ends of the magnesium oxide panel 20 in the direction of high heat energy, and the steel plate 30 presses the middle of the magnesium oxide panel 20.
It should be noted that the steel plate 30 does not contact with the inner rear side surface of the elevator door body 10, i.e. a certain gap is left between the two, so that the elevator door body 10 is reduced to directly conduct heat energy to the steel plate 30, the structural strength of the steel plate 30 is improved when a fire occurs, the steel plate 30 is not easy to deform, and thus the two ends of the glass magnesium plate 20 are prevented from being bent in the direction of high heat energy; the fine nanometer network structure of aerogel 40 restricts the heat propagation effectively for the indoor temperature of elevator can not too high, provides the guarantee for personnel's security.
Compared with the prior art, the fireproof elevator door provided by the utility model has the advantages that through the arrangement of the steel plate 30, the steel plate 30 is tightly attached to and tightly presses the surface of the glass magnesium board 20, the bending of two ends of the glass magnesium board 20 to the direction with high heat energy is limited, the fireproof performance of the glass magnesium board 20 is further improved, the safety of personnel in the elevator room is greatly improved, and the safety of the personnel in the elevator room is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
