Description

High residential building is without electric automatic fire damper

One, high residential building safety?

Acceleration along with the urban modernization footwork, the highrise building erect image in China city is emerged rapidly in large numbersBamboo shoots after a spring rain and is equally stood the sky in the city, and floor is built higher and higher, the high-rise fire that arrives with it, also accompany such as shadow, high-rise malignant fire again and again constantly occurs, as long as it shrouds the mind at high-rise buildings, and everybody is nervous worried, because bottom one family breaking out of fire, resident family above it just is unable to escape bad luck, although aerial ladder is also more and more higher, role is very limited in high-rise fire, because it is subject to the restriction of a lot of objective factors, such as narrow field, ground is uneven, wind-force is excessive etc., the capital affects the ability of its actual motion, so high-rise fire is being engulfed countless victims' life just as the demon, and brings great property loss for country and individual, in face of it, everybody feels simply helpless.The present high-rise fire fire-fighting difficult problem that become international.So far go back the neither one effective method and solve it.

Two, the fire fighting device of high residential building can not put in place fully and also be not suitable with present development

We know that the outfit of the fire fighting device of the present high residential building of China all can not put in place fully, and also science not is in addition without personal management and on the shelf for a long time, when treating the big fire burst, all without actual effective utilization.Often appearance fire plug when big fire occurs does not go out the serious problems of water.The fire plug of not mentionleting alone in the high-rise building does not go out water, and the fire plug on ground is also often anhydrous desirable.The beginning of this year at the end of last year, only in 4 months, three great high-rise fires just occured in China, i.e. the high-rise big fire in Chongqing on August 9th, 2010; Shanghai high-rise big fire on November 15 in 2010, Shenyang high-rise big fire on February 3 in 2011, they all be from fire bed burn top layer always, fire department is felt simply helpless, and wherein the high-rise big fire of that time of Shanghai causes 57 people dead altogether, the people is in hospital more than 70 great casualties and the heavy losses of property, allow common people shock, because taking place frequently of high-rise fire, various high-rise fire escape apparatus also meet the tendency and look unfamiliar, but this can only say passive fire protection.Yet its effect is also as one wishes not to the utmost.

According to the researcher of relevant department of Ministry of Public Security measuring and calculating, big fire burns the time that 100 meters top layer only needs half a minute from bottom, and this is too fearful.

Does three, how big fire spread to top layer fast from bottom?

Everybody knows, water flows to lower from eminence, can fire opposite, former thermal current of flaring up is that straight line rises, after the low layer burning things which may cause a fire disaster is scurried out from window, directly upwards layer window is altered, the glass window of last layer window was being closed, big fire also can be burnt fragmentation with glass very soon and be come off, at this moment big fire just last layer within doors the combustion-supporting lower of comburant alter to last layer window more, like this, big fire burns top layer from low layer always just as relay, according to these special circumstances of high-rise fire, I have invented again this " high residential building is without electric automatic fire damper " it have been different from ' fire screen ' on the basis of invention " high residential building is without electric automatic shutter " and " high residential building fire prevention windowsill " by ruminating over, and also am different from ' fire prevention windowsill ', but it is the important supplement of above two kinds of high floor fireproofings and perfect.Because, because the diversification of building constructions material and profile, the highrise building that has namely is inconvenient to fill ' fire screen ', also be not suitable with and build ' fire prevention windowsill ', such as those senior office premises full glass curtain walls buildings of picture, to load onto this be attractive in appearancely not only can be flattened on can prevent fires but also can regard ' fire resisting shield ' of billboard below the windowsill drawing at ordinary times but it adapts to fully.In case breaking out of fire, need not electric energy it too the automatic spring fireguard block the infringement of big fire and burning things which may cause a fire disaster guided into direction away from window.

Four, the moulding of ' fire resisting shield ', structure, material, and installation requirement:

See accompanying drawing---Fig. 1. Fig. 2. Fig. 3. Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8,

' fire resisting shield ' minute: fireguard, fixedly channel-section steel, telescope support, meltable nylon yarn, adjust knob, annex: self-tapping screw and slotting axle 1. fireguards

See Fig. 1, Fig. 1 dwindles ' fire resisting shield ' front view at 15: 1; The 1st, windowsill; The 2nd, " fire resisting shield ", this piece fire resisting shield designs for multi-groove shape, and it is best to adopt multi-groove shape to design its fire-proof function, and it can accelerate the flowing velocity of HTHP; It is exactly one according to the width of resident family's window and one fixed rectangular " fireguard ", the height of each " fireguard " be the same be 70cm.If the width of window is 110cm, that will be added the window left side and stretch out 60cm, it is that length is respectively dwindled the little 20cm of 10cm cocondensation that the footprint left and right sides both direction that " fireguard " that 60cm equals this window of 60+60+110=230cm should be its ' fire prevention windowsill ' of inventing previously with me of the long 230cm of high 70cm X is stretched out on the right, why do this " fireguard " shorten 20cm than ' fire prevention windowsill '? because its table top will hang down 35cm than the daylight opening DLO windowsill of ' fire prevention windowsill ' after this ' fire resisting shield ' launched, namely move down 35cm, namely burning things which may cause a fire disaster has been pushed away far 35cm (seeing Fig. 3) simultaneously; See Fig. 2, Fig. 2 dwindles fire resisting shield rounding state side view at 10: 1; The 1st, windowsill; The 2nd, " meltable nylon yarn " just locating the fire prevention state; The 3rd, " telescope support " is in rounding state; The 4th, " fixing channel-section steel; The 5th, be in " fire resisting shield " of rounding state; Other sees Fig. 3, and Fig. 3 dwindles ' fire resisting shield ' deployed condition lateral view at 10: 1; The 1st, be in " telescope support " of extended configuration; The 2nd, " fireguard " is in the fire prevention state at linear about 45～50 degree oblique angles, slope; The angle at this oblique angle wants science to hold, and angle is excessive too small all not all right.This linear oblique angle, aerodynamic slope that meets can prevent that just downstairs big fire is to the key of vertical spread; See Fig. 4, Fig. 4 dwindles ' fire resisting shield ' deployed condition side-looking aerodynamics diagram at 10: 1; We know, the room that catches fire can produce high temperature, there is high temperature that high pressure is just arranged, speed when high temperature and high pressure is altered up from lower floor's window is very fast, it directly adsorbs body of wall and upwards spreads fast, alter in big fire with ' fire resisting shield ' and meet, the direction that big fire just can guide along the sloping line of ' fire resisting shield ' ejects fast, and this direction is just away from the direction of last layer window.Because big fire high temperature ejects fast along the direction that ' fire resisting shield ' guides, at this moment the top of ' fire resisting shield ' can form a relative low pressure and constantly replenish the peripheral low-temperature and low-pressure of being taken away because of rapid flow by HTHP.This low pressure is to change along with the intensity of a fire of lower floor's big fire; the larger low pressure of the intensity of a fire is also just larger; the cold air of other direction compiled to ' fire resisting shield ' top around this low pressure ceaselessly received; thereby the space of a shielding of self-assembling formation high temperature; the upper strata window is in a kind of comparatively safe temperature environment under this shielding protection all the time.

2. fixing channel-section steel

A fireguard should have two " fixedly channel-section steels ", respectively at the two ends of fireguard, mainly be used for fixing ' fire resisting shield ', some fixing holes of using are arranged above it, on the channel-section steel slotted eye be used for fixing on body of wall and circular hole is inserted axle and is used for being connected to a fixed with ' fire resisting shield ', all fixed screws and connect that to insert axle all should be stainless; See Fig. 5, Fig. 5 dwindles " fixedly channel-section steel " diagram at 10: 1; A is the channel-section steel front view; A-1 is the scarf of channel-section steel upper end; A-2 is that channel-section steel is connected slotting axle with telescope support; A-3 is oval-shaped self-tapping screw fixing hole; A-4 is that channel-section steel is connected slotting axle with fireguard; B is the channel-section steel side view; C is the channel-section steel back elevation

3. telescope support

" telescope support " two has been effect fixing and that draw ' fire resisting shield ' in, and it is folding and stretching, extension with the gathering of ' fire resisting shield ' and expansion.Add the bullet semi-annular jade pendant in " telescope support ", when " meltable nylon yarn " had no progeny by the big fire high temperature melting, spring can move along with the direction that ' fire resisting shield ' tilts and the rapidly expansion of promotion ' fire resisting shield ', block along the big fire of altering on the body of wall with the fastest speed, cut off big fire to the path of vertical spread.See Fig. 6, Fig. 6 dwindles " telescope support " diagram at 10: 1; D is that " telescope support " is in the folding state diagram; The part of spring cavity is housed, and is the major part of stretching; Fig. 6-E is diagram after " telescope support " stretches; E-1 is the sleeve that " telescope support " is connected with " fixedly channel-section steel " upper end; E-2 is the spring cavity of " telescope support "; E-3 is the scalable part of " telescope support "; E-4 is the sleeve that " telescope support " is connected with " fireguard ".

Meltable nylon yarn with adjust knob (fire resisting shield core component)

The core component of ' fire resisting shield ' is the same with ' fire screen ', and it is exactly " meltable nylon yarn ", sees Fig. 7, and Fig. 7 is the available existing fishing silk thread of core component " meltable nylon yarn " of ' fire resisting shield '.Large, the anti-sunlight of its intensity, refuse rainwater, anticorrosive, but it is afraid of big fire high temperature most, so be its " meltable nylon yarn ".' fire resisting shield ' should keep certain angle of inclination when relatively drawing in, both outwards slightly inclinations of certain angle, this gradient is very important, best inclination should be: in the situation that does not have nylon yarn to be fastened, one lets go ' fire resisting shield ' will be outwards mobile with the center of gravity force direction, at this moment " telescope support " can promote rapidly ' fire resisting shield ' expansion under the effect of spring, otherwise at this moment use " meltable nylon yarn " to replace handgrip ' fire resisting shield ' to snarl, make ' fire resisting shield ' be in all the time this fireproof heeling condition.The like this effect that loses fixing ' fire resisting shield ' in case meet that big fire high temperature " meltable nylon yarn " will be fused by big fire high temperature immediately, the in addition effect of " telescope support " spring, ' fire resisting shield ' can launch moment, stop the big fire of altering, here in inferior prompting explanation, the winding method of nylon yarn, winding method as ' fire screen ', namely can only fix the two of " meltable nylon yarn ", any position, stage casing all can not wind with one circuit, in case nylon yarn can not partly still snarl ' fire resisting shield ' and affect development rate in whole absent-mindedness of moment.And the fixing and adjustment degree of tightness of " meltable nylon yarn " also need have " adjustment knob " to finish, and sees Fig. 8, and Fig. 8 is that 1: 1 " adjustment knob " exploded view reaches fixedly self-tapping screw; The 1st, fixing self-tapping screw; The 2nd, " adjustment knob "; the 3rd, " adjustment knob " firm banking front view; the 4th, " adjustment knob " base self-tapping screw is eye fixedly; the 5th, " adjustment knob " firm banking side view; the 6th, " adjustment knob " rotation set side view; the 7th, the ply-yarn drill hole on " adjustment knob " rotation set, the 8th, cover is inserted in the protection of " adjustment knob " plastics, and the 9th, the notches for wire on the cover is inserted in the plastics protection.

5. accessories section: fixedly self-tapping screw and the fixing axle of inserting

" the fixedly channel-section steel " of ' fire resisting shield ', " telescope support ", screw, slotting axle etc. all should be stainless, because the fixing self-tapping screw of body of wall, the fixing axle of inserting with other parts, time one is long under the effect of sunlight rainwater, if get rusty or oxidation, ' fire resisting shield ' can occur tilt and can not normally launch, or come off and damage, both made not run-off the straight, the stain that comes off, becomes rusty also can affect with rainwater trickling attractive in appearance, so must use stainless steel material.

6. the excellent characteristics of fire resisting shield:

' fire resisting shield ' is to the important supplement of ' fire screen ' and ' fire prevention windowsill ' and perfect, because the at present material of highrise building and the diversification of contour structures, and the suitable dress ' fire screen ' that has and should not fill ' fire prevention windowsill '; The newly-built building that has easily fills ' fire prevention windowsill '; Above two kinds that have all are not suitable for installing, and adopt full glass curtain wall as high-grade office building, but its most suitable installation is this flexible convenient to both and can double as that billboard uses

' fire resisting shield '.The Ministry of Public Security once required China's high-rise building must will have " Fireproof refuge layer " must will have every 10 layers namely that one deck is inaccurate to be decorateed more than 10 layers, was on " Fireproof refuge layer "; Be ready to do like this but go back till now the neither one developer, reason is very simple, and developer's interests suffer damage; ' fire screen ' and ' fire resisting shield ' arranged now, and the developer can select a kind of better suited between these two kinds just to load onto one deck ' fire screen ' or ' fire resisting shield ' gets final product every 10 layers in highrise building.Also just there has been certain safety guarantee in building, whole like this building, if breaking out of fire at most also can only spread 10 layers, and the people who is burnt layer also can evacuate to rapidly and takes refuge more than the firebreak device layer is installed.The developer also reduced every 10 layers will vacant one deck out as the loss of refuge story.This requirement of the Ministry of Public Security is wished in the near future can be accomplished.By the way, those buildings that ' fire screen ' can be installed can be installed this ' fire resisting shield ' equally, and ' fire resisting shield ' is fit to the building of all architectural appearances.

' fire resisting shield ' can select different materials to process, stainless steel, stainless iron, reinforced aluminum, composite fireproof plate etc.Ordinary aluminum plate can not be used as ' fire resisting shield ', because the easy oxidation of ordinary aluminum plate, yielding.Only have through the reinforcement aluminium sheet of strengthening processing and could suit as ' fire resisting shield '.The advantage of reinforced aluminum is processing attractive in appearance, firm, light, easy, easily transportation, easily installation.Metal ' fire resisting shield ' can design the various floral designs of processing, and after processing such as contrasts such as adopting polishing, inferior light, hair side, it is luxurious beautiful that exterior quality can seem; Character and the different of classification according to the building also can be designed to billboard to ' fire resisting shield ' in addition, and billboard easily adopts color ink jet printing to process, and characteristics are bright in luster eye-catching.Installing and using so this ' fire resisting shield ' does not only affect the attractive in appearance and quality that also can promote building attractive in appearance in building.If any resident family want ' fire resisting shield ' come usefulness when large windowsill, Na Ta can directly remove " meltable nylon yarn " and launch ' fire resisting shield ', welds a stainless (steel) wire gridiron and loads onto and get final product.So large windowsill that changes domestic environment realizes that at once it can be prevented fires and can lay out the flowers and plants rockery potted landscape of liking itself.But the date that sunlight arranged is a little small articles of air dry also.The instantaneous expansion of dwelling environment, mood is also suddenly seen the light.Use if double as billboard, that kills two birds with one stone especially again, and the advertising expense of withdrawal can be offset the expense of installation ' fire resisting shield ' fully, and it makes vast high-rise buildings that a new selection arranged again, and safety primarily guarantees especially certainly.

' fire resisting shield ' is three chains of rings of high residential building fire prevention series with ' fire screen ' and ' fire prevention windowsill ', and their all linked with one another complementing one another are improved the fire safety problem that has thoroughly solved high residential building each other.It is first-selected that it will inevitably become from now on the high residential building fireproof, and its invention will bring great change and safety guarantee to social life, also is the needs of social development, at present international and domesticly just perplexed by the problem for high-rise fire.Its invention will promote China's fire-fighting cause and step into forward major step.Reduce great casualties and the heavy losses of property will for every year country and society.It is with out and out burden and the pressure that alleviates China's fire department and fire fighters.For society brings stablely, on the other hand, the economic worth of these innovation and creation and social benefit are huge.The innovation and creation that some is great and technological innovation need energetically support and the publicity of national departments concerned, even will have certain enforceable policy to ensure the popularization implementation.Particularly as this firebreak device.Before not having breaking out of fire, everybody has idea of leaving things to chance, the extremely long-pending attitude that change this idea of leaving things to chance to put prevention first into, allow and have in people's human brain " take precautions against natural calamities be better than ask calamity " the science idea.Only have people to live in the safe ring mirror, society just can stabilize, and the modern footwork of science just can advance at a quick pace.
