Description
Technical field
The present invention relates to a kind of fire resistant doorsets, specially wooden heat-insulating fireproof door, belong to security appliance field.
Background technology
China's fire protection facility is the most perfect at present, and fire resistant doorsets can not give full play to it in a fire should
Some effects, on the contrary, very likely cause the generation of obstruction safe escape phenomenon because of the damage of fire resistant doorsets.I
The security against fire consciousness of the current people of state is thin；Some uses unit management to be not good at, and not causes its management
Pay much attention to；Publicize not in place.In security against fire inspection is unanimous, some units one run into fire supervision department and send out
Existing the problems referred to above, extensively carry out fire fighting device and use, safeguard, manage communication and education, make great efforts to improve people's
Full consciousness and sense of self-protection are sent out in fire-fighting；The unit being provided with fire resistant doorsets is extensively carried out fire-fighting peace umbrella know
Know publicity training, strive allowing everyone know about the use of fire resistant doorsets, safeguard, manage basic general knowledge,
The maintenance of the conscious door participating in life, manage, make its moment combat ready/readiness；Put up at fire resistant doorsets
Fire resistant doorsets purposes, function and handy state and use basic demand, effectively prevent to cause because of extra exit locking
The fire incident of group's dead group wound, whole nation major part provinces and cities have been widely used in technique, and effect is notable,
Some safety doors still have several drawbacks that part, many safety doors are merely able to be opened to 90 degree at present,
When fire occurs, use and there is bigger potential safety hazard.
Heat-insulating, fire-preventing is the behave of a kind of necessity for safety door.Fire resistant doorsets present in prior art
Fire proofing material numerous, on the one hand be the performance issue of fire proofing material so that fire-proof and thermal-insulation is not ideal,
On the other hand it is the setting in the position of safety door, again such that fire resistant doorsets flameproof effect is less of fire proofing material
Substantially.Additionally, the not charge ratio of fire-proof heat-insulating material is bad present in prior art so that using
Process China makes fireprotection layer and thermal insulation layer to get a desired effect.Therefore for the problems referred to above I
Propose a kind of wooden heat-insulating fireproof door.

The present invention in use, the once breaking out of fire of normally opened fire resistant doorsets, can be realized by coordinated control system
It is automatically switched off, is effectively guaranteed fire resistant doorsets reliable closedown in a fire, thus reaches it every cigarette, back-fire relief
Should have effect.Normally opened fire resistant doorsets do not have big district with normally closed fire resistant doorsets manufacturing in basic configuration
Not, it is to be replaced with the door closer of normally closed fire resistant doorsets to prevent with the normally opened of automatic fire alarm coordinated signals
Fire resistant doorsets can freely be opened 180 degree of degree, and close smoothly, revolutionize by fire automatic opener
Normally closed fireproof door closer maximum opens 90 degree degree angles and to using the drawback made troubles, and this kind is released
Put device and once close fire resistant doorsets, in the case of anti-fire door releaser not yet resets, in fire due to panic and
Escaping anxious, the people of escape cannot take into account at all and close the fire resistant doorsets having been switched on, at this moment door opener sense
Just can be closed by opposite house by after smog, it is ensured that smog does not enter indoor, the safety of protection people.
The operation principle of the present invention: will pass through when wooden heat-insulating fireproof door experiences smog or high temperature
Signal is passed to siren by sensor, and siren sends alarm, while sending alarm, it is possible to profit
With door opener, door is opened, if if smog gets up to have only to from Indoor Combustion push away handle or draw handle
Simply wooden heat-insulating fireproof door can be opened, because the hinge that wooden heat-insulating fireproof door is installed can
The rotation of 180 degree, will not in case of emergency have influence on people and open the door, can be quick when producing fire
Personnel are withdrawn scene of fire, it is ensured that people's safety；Thermal source can be cut off by the internally installed thermal insulation layer of door,
Protecting the temperature within house, flame resistant glass can allow indoor people see scene of fire clearly, thus adopts
Take rescue measure trapped personnel is made to sue and labour.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment,
And without departing from the spirit or essential characteristics of the present invention, it is possible to real in other specific forms
The existing present invention.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and
Being nonrestrictive, the scope of the present invention is limited by claims rather than described above, therefore purport
All changes in falling in the implication of equivalency and scope of claim are included in the present invention.
Should not be considered as limiting involved claim by any reference in claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, but the most each reality
Mode of executing only comprises an independent technical scheme, and this narrating mode of description is only for understand
Seeing, those skilled in the art should be using description as an entirety, and the technical scheme in each embodiment is also
Other embodiments that it will be appreciated by those skilled in the art that can be formed through appropriately combined.
