Description
Technical field
The present invention relates to door manufacturing technology field, more particularly to a kind of intelligent fireproof door.
Background technology
The many methods and skill for manufacturing intelligent fireproof door and intelligent fireproof door core are had been developed over for a long time
Art.But the great majority in these prior art designs can not be well adapted for full-automatic manufacture process.At present on the market
Intelligent fireproof door, including fireproof core board and the fireproof decorative top for coating the fireproof core board, fireproof core board is with aluminium silicate wool or swollen
Swollen pearlite wool is main material, however, the fireproof core board of intelligent fireproof door is with aluminium silicate wool as main material, what it was produced
Flue gas has toxicity；The fireproof core board of intelligent fireproof door wants material based on expanded pearlite rock wool, and its intensity and fire prevention are burnt
Poor performance.
General, intelligent fireproof door is referred to and can meet that within a certain period of time fire stability, integrity and thermal insulation will
The door asked, is mainly used in fire wall opening, staircase gateway, evacu-ation walk, pipeline well head of Building Fire Protection subregion etc., puts down
It is usually used in personnel to pass through, can prevents propagation of flame when there is fire and prevent combustion product gases from flowing, intelligent fireproof door is earliest
Vessel industry is applied to, in recent years, as its importance between floors that increases of skyscraper is projected increasingly, in being building
The one of most important fire prevention measure, however, at present intelligent fireproof door is utilized made by iron material mostly, and applies paint in surface
Decorate within doors with coordinating, but this kind of practice is when fire occurs, it is harmful that pigment can produce chemical gas, and iron material itself
Heat conductivity is good, therefore when fire occurs, intelligent fireproof door can very scald, and makes one directly to open, it is necessary to look for it
He opens article indirectly, wastes escape time, and if scene of fire temperature it is higher when, this kind of intelligent fireproof door can produce change
Shape, leads to not open, it is necessary to failure mode unlatching, and same decreasing is rescued or escape time, furthermore, this kind of intelligence
The cost of type fire resistant doorsets can be in any more, causes the cost up for building dealer, makes consumer that more expense need to be used just commercially available yet
Buy, thus building owner save funds be first it is top-priority under, often only demand and pass through inspection, not full and accurate accounting
The fiery carrying capacity of building, even with cheap underproof fireproof building material, is especially topped the list with unqualified intelligent fireproof door.
But, many solutions, such as Chinese patent (application number have been had in prior art：
A kind of intelligent fireproof door 200910005201.X) is disclosed, it includes flame resistant glass and the support for supporting flame resistant glass
Part, and the support member include the elastic component contacted with two surfaces of flame resistant glass marginal portion, for supporting the bullet
Property component strengthen framework and be fixed on support and the fixed plate corresponding with two surfaces for strengthening framework.The technical side
Case is directed to commercialization problem, it is believed that fireproof glass costly, increased production cost used in universal intelligent fireproof door
Burden, limits supply and demand.Based on keeping on the basis of outstanding fire protecting performance, reaching effect attractive in appearance, frame-type support, bag are employed
The supporting part and fixed plate of elastic component are included, while realizing fire-proof function, production cost is reduced, but the technical scheme
The basic element of character has still used flame resistant glass, reduces the DeGrain of production cost, and flameproof effect is not obtained further
Raising.
For another example the A of Chinese patent CN 103726766 disclose a kind of intelligent fireproof door, it is characterised in that include：Two
Door pillar, is oppositely arranged；Accommodating mechanism, is arranged on the top of two door pillars；Several panels, are sequentially overlapped from bottom to top two
Between the individual door pillar, and can successively be stacked in the accommodating mechanism；Guiding mechanism, guides several panels in the door
Move back and forth between post and the accommodating mechanism；Drive mechanism, drives the guiding mechanism to drive the panel movement；It is described to lead
It is arranged on the door pillar and the accommodating mechanism to mechanism, several panels is caused from bottom to top by the guiding mechanism
It is sequentially overlapped between two door pillar or is successively stacked in the accommodating mechanism, realizes the closing of the intelligent fireproof door
Or open.In the technical scheme, traditional lath is replaced using panel, while with fire insulation and heat-insulated effect, making simple；
Intelligent fireproof door is closed by way of superposition, and panel can be successively stacked at the top of it when intelligent fireproof door is opened,
It is simple and quick.Although the technical scheme using panel replace traditional lath, closed by way of superposition it is intelligent anti-
The means such as vent, while having given up using flame resistant glass, can reach good flameproof effect, but, it is anti-for intelligent
The flexibility ratio aspect of the intensity, service life and intelligent fireproof door itself of vent itself is still short of.
The content of the invention
To overcome intensity, service life, intellectuality and the intelligence of intelligent fireproof door present in prior art itself
The problem that the flexibility ratio aspect of type fire resistant doorsets itself is still short of, the invention provides a kind of intelligent fireproof door.
The technical solution used in the present invention is：A kind of intelligent fireproof door, including door-plate and it is sleeved on door periphery
