Abstract
The utility model discloses a kind of fire resistant doorsets, including door body and doorframe, the cross section that the door body is used for the edge coordinated with doorframe is ladder structure of right angle, doorframe position corresponding with the edge is tapered plane shape, the tapered plane is consistent with the central plane gradient of right-angled trapezium, seamless applying both when door body is closed.The utility model is rational in infrastructure, ingenious in design, its shape and structure by changing door body and doorframe, on the premise of the normal use of fire resistant doorsets is not influenceed, not only eliminates the design of expanding sealing strips, cost-effective, and improves the sealing property of fire resistant doorsets.Therefore, the utility model is suitable to popularization and application.
Description
Technical field
The utility model is related to a kind of fire resistant doorsets.
Background technology
Common fire resistant doorsets, the edge corner angle for generally all being used to coordinate with doorframe in door body are designed using L-shaped structure, then
Sealing strip is provided with, that fire resistant doorsets are realized using sealing strip chance high-temperature expansion is fully sealed (as shown in Figure 1), Jin Erda
To cut-off scene of fire, it is to avoid pyrotechnics is stretched to the purpose of other safety areas.But, this sealing strip must be reached in temperature
Expansion sealing could be realized after to certain altitude, and at the initial stage of fire generation, temperature not yet rises to sealing strip expansion requirements
Before, there is gap between fire resistant doorsets and doorframe, pyrotechnics reaches safety area easily through gap, so to personal safety with
Public property causes certain infringement.And if can be caused using the sealing strip that low temperature is expansion in door body edge edges and corners again
Fire resistant doorsets are difficult to switch, and influence routine use.Therefore, the fire-proof function of fire resistant doorsets is realized by sealing strip dilating principle, is
Exist disadvantage, it is necessary to improve.
Utility model content
For above-mentioned technical deficiency, the utility model provides a kind of fire resistant doorsets, and it solves fire prevention by structure design
Between door in door body and doorframe the problem of sealing.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of fire resistant doorsets, including door body and doorframe, the cross section that the door body is used for the edge coordinated with doorframe are right angle
Trapezium structure, doorframe position corresponding with the edge is the central plane gradient one of tapered plane shape, the tapered plane and right-angled trapezium
Cause, it is seamless applying both when door body is closed.
Further, the cigarette sense spray system for being sprayed towards door outside is additionally provided with the doorframe.
Compared with prior art, the utility model has the advantages that：
(1) the utility model is rational in infrastructure, ingenious in design, and the shape at its edge for coordinating door body with doorframe is changed by L-shaped
For right-angled trapezium, and make the matched edge of doorframe into tapered plane shape, so that before not influenceing fire resistant doorsets normally to use
Put, not only eliminate the design of expanding sealing strips, and improve the sealing property of fire resistant doorsets, when running into fire, pass through
Sealing can quickly be realized by closing fire resistant doorsets, it is ensured that the personnel of safety area and the safety of equipment.
(2) the utility model is provided with cigarette sense spray system on doorframe, automatic sensing and can be carried out when occurring fire
Spray, is realized to the atomization of flue gas and putting out by water for pyrotechnics, so that the danger of upper reduction fire to greatest extent.
Brief description of the drawings
Fig. 1 is existing fire resistant doorsets door body and the cooperation schematic diagram at doorframe edge.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is door body and the cooperation schematic diagram at doorframe edge in the utility model.
Wherein, the corresponding parts title of reference is：
1- door body, 2- doorframes, 3- cigarette sense spray systems.
Embodiment
The utility model is described in further detail with embodiment for explanation below in conjunction with the accompanying drawings, and mode of the present utility model includes
But it is not limited only to following examples.
Embodiment
As shown in Fig. 2 the utility model provides a kind of Novel fire-proof door, including door body 1, doorframe 2 and cigarette sense spray system
System 3.The cross section that the door body 1 is used for the edge coordinated with doorframe 2 is ladder structure of right angle, the doorframe 2 and the edge pair
The position answered is tapered plane shape, and the tapered plane is consistent with the central plane gradient of right-angled trapezium, seamless contact both when door body is closed,
As shown in Figure 3.And described cigarette sense spray system 3 is then arranged on doorframe 2.
When meeting fire, quick closedown door body 1, now, the central plane of its edge right-angled trapezium and the tapered plane seamless paste of doorframe 2
Close, form sealing state, it is to avoid outside flue gas enters, it is ensured that the personal security of safety area；Meanwhile, cigarette sense spray system 3 is felt
Cigarette is simultaneously sprayed towards door outside, realizes to the atomization of flue gas and putting out by water for pyrotechnics, the danger of fire is reduced to greatest extent.
The utility model not only eliminates the design of expanding sealing strips by changing the matching relationship of door body and doorframe, saves
The about buying of expanding sealing strips and assembly cost, and improve the sealing property of fire resistant doorsets, make it can when running into fire
Sealed with quick realization, and then effectively ensure that the safety of personnel and equipment.
Above-described embodiment is only one of preferred embodiment of the present utility model, be should not be taken to limit of the present utility model
Protection domain, it is all body design thought of the present utility model and mentally make have no the change of essential meaning or polishing,
The technical problem that it is solved is still consistent with the utility model, should be included in protection domain of the present utility model it
It is interior.
Claims (2)
1. a kind of fire resistant doorsets, including door body (1) and doorframe (2), it is characterised in that the door body (1) is used to coordinate with doorframe (2)
The cross section at edge be ladder structure of right angle, the doorframe (2) position corresponding with the edge is tapered plane shape, the tapered plane
