The specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
The utility model is from hydrodynamics and thermodynamic (al) principle, see Fig. 1: building construction fire-fighting exhaust, safety channel system of the present utility model, be provided with a fire-fighting exhaust, safety window 1 at each the room wall of building construction or the position, the top on roof, this fire-fighting exhaust, safety window 1 is outer to be provided with an opening up, the subchannel 2 that communicates with it, the opening part of this subchannel 2 is lower than the least significant end place to the subchannel 2 in next level room that should the room, and the subchannel 2 in each room communicates with a main channel 3 up and down, the outlet 4 of this main channel 3 is at this roof that builds a building, promptly the flue gas that comes out from subchannel 2 openings etc. flows into the main channel 3, and flows out from the outlet 4 of the main channel 3 of being located at this roof that builds a building.In the present embodiment, outlet 4 places of main channel 3 are provided with one with the wind and moving blast cap 5, shown in Fig. 5-A, 5-B, 5-C, blast cap 5 comprises pedestal 6 and housing 7, this pedestal 6 is fixed on outlet 4 places of main channel 3, one column 8 is fixed on the pedestal 6, housing 7 is enclosed within on this column 8, and the import 9 one end opening diameters of this housing 7 are greater than the outlet 4 of main channel 3 and entangle the outlet 4 of this main channel 3, outlet one end of this housing 7 and entrance point 9 are vertical and to be arranged to subtended angle be α ° tubaeform, and tubaeform major part outwardly.This flaring outlet is can be around column 8 rotation and under the distinguished and admirable effect of streaming that produces when crossing horn mouth under the effect of wind-force, the inner low pressure that forms of horn mouth, the air-flow in the horn mouth can be got rid of the flue gas in the passage flowing out under this hypobaric attraction outside the trend horn mouth.Wind-force is big more, and this drainage is strong more! Thereby strengthened the air draft effect of " stack effect "! Loudspeaker opening part 10 is provided with metal guard 11 and sneaks into to prevent foreign matters such as small worm.Whole blast cap is made with resistant materials such as stainless steels, to prolong its application life, reduces maintenance work and expense.
In the utility model, can be provided with several main channels 3 in the building construction, the subchannel 2 in adjacent each room communicates with a main channel 3 wherein, the adjacent room of building construction can be combined into many between the combined type fire-fighting exhaust, safety channel system that share of room.
About combined channel, now the combination passage that share with Unit four is that example illustrates: see Fig. 2, Fig. 3 and Fig. 4, the A-A section is the vertical vertical tangent plane of passage, and the B-B section is the cross section of passage by the security against fire exhaust window, and C is that inside and outside part is isolated, the hermetically-sealed construction partial enlarged drawing.Fire safety passage can be designed to inside and outside separate type, in order to construction and maintenance.Passage cross section B-B is the Back Word type, and passage skin 12 can be used the square shape that the building facade has fillet in making.Internals 13 are the square shape of 4 jiaos of oriented external radiation dividing plates, and inside and outside two are divided into main channel 3 and 4 subchannels 2 up and down with passage.4 subchannels 2 up and down communicate with the fire-fighting exhaust, safety window 1 of unit separately respectively, pyrotechnics from the fire-fighting exhaust, safety window 1 of unit separately enter separately subchannel 2 upwards, in the time of will arriving upper unit fire-fighting exhaust, safety window 1, enter main channel 3 from the opening part of the top of internals 13.For ease of the smooth circulation of pyrotechnics, the lower end of internals 13 is made outside tubaeform, reducing the resistance of air-flow, enters main channel 3 from separately subchannel 2 apace smoothly in order to air-flow and discharges.Fire-fighting air draft escape way skin 12 is at the period of the day from 11 p.m. to 1 a.m that builds a house, available punching block is made the square shape passage that makes progress continuously, internals can be made modular prefabricated with the material of light-weight refractory, length is the height of corresponding each floor, to guarantee accuracy, the interchangeability of respective outer side edges, improve yield rate, alleviate construction weight.Square groove 14 is arranged at each dividing plate top of internals, and fire-resistant soft band 15 is installed therebetween, each passage of ectonexine is separated and seals, and avoids mutual taint of odour of each passage and collision.Subchannel 2 is too narrow to even child also can't enter any unit from feeder connection, to stop to cause the public security problem guaranteeing under the situation of circulation area narrow and wide trapezoidal of formation naturally up and down.
In case breaking out of fire, the blast cap 5 that flue gas moves with the wind through security against fire window 1, subchannel 2, main channel 3 and top is discharged, thereby form a flow field: though red-hot, the low weight air-flow of sheaf space is billowing on the room, but the lower layer space in room, fresh, heavier cold air constantly flows in a steady stream, form the line of demarcation between red-hot flue gas and the fresh cold air, this has improved the advantage that environment and fire fighter sue and labour of withdrawing of disaster affected people greatly.Except that the scene of fire, other unit can not be subjected to the influence of the condition of a disaster up and down.In the life that Here it is " stack effect " of called optical imaging.We burn little chimney, the smokestack of power plant, the high converter system to the molten steel boiling of the interior temperature of steel mill that bavin is cooked, because flue gas has the rational flow direction, the influence of any safety can not arranged to the staff on next door.
Adopt the remarkable advantage of building construction of the present utility model, anyone with a discerning eye can easily see that, fire-fighting of the present utility model exhaust passage system is again the passage of a vented exhaust very naturally, when being not only breaking out of fire, it just can use, and be 24 hours all day long all play a role, have the structural element of effect of equal importance, indispensable, necessary building construction with building structures such as housing windows, elevator shaft, thereby changed the major defect that present building construction does not have reliable security against fire design! It both can undertake security against fire, had accomplished to change the air-conditioning important task of using the irrational vented exhaust of Hairdryer at present from top to bottom again.So described fire safety passage system has also just become the safe passageway system of fire-fighting exhaust naturally.In view of the above, under the situation that does not influence the house function, can be with combined type fire-fighting exhaust, safety channel systems such as the room share between how being combined into one deck house, to reach the reasonable utilization in space, the purpose of saving more of material, cost.
Adopting another advantage of the present utility model is to existing house, comprise that existing houses such as house, office building, large-scale arenas, market can both transform in view of the above, thereby improve its security against fire function, just cost is than new house height, but much smaller than the cost that modernized fire prevention is set.
Obviously, adopt building of the present utility model to be aided with modern fire prevention again, can adopt suction, exhaust blower up and down at fire-fighting exhaust, safety passage, with technical measures such as pyrotechnics monitoring sprays, the security against fire rank in house will further improve in the room.
Obviously, at each room fire-fighting exhaust, safety window exhaust fan being set is reliable, the simplest method.
The superjacent air space that requires each room of stack effect itself seals.Yet the door and window Chang Kaichang in room closes, can not seal, so should satisfy the door top on the structure seals greater than the space of fire-fighting exhaust, safety window 1 height, the illumination problem can solve with the bright window of seal glass, with this, all activities in the room: people's breathing, the hot gas that all thermals source produced all float and assemble in this, and can only discharge from the fire-fighting exhaust, safety window 1 of the top, room, even scavenge to guarantee the room temperature difference also can form stack effect when little, change to fresh air.
The characteristics of stack effect are that chimney is high more, and the function of suction pyrotechnics is just strong more.The chimney of power plant is exactly this reason up to tens of rice.So the utility model is specially adapted to the favorite of modern city---modern highrise building.The also corresponding meeting of high more its stack effect of building is higher.This advantage is that schemes such as the aerial ladder, helicopter fire fighting of any " modernization " all can not be compared.This shows that using the utility model on house floor constructure is rational, science.
The characteristics of stack effect are that chimney is high more, and the temperature difference is big more, and the effect of suction pyrotechnics is good more.Noted earlier all is the situation of the condition of a disaster when serious, every key element of stack effect all reaches peak, this is just as disaster taking place and the on-the-spot serious situation that nobody sues and labours again and again at present, we create this condition, when even the condition of a disaster is so serious, the worst this part, unit, scene of fire of also only bringing disaster to, will not as at present, the condition of a disaster can expand ouster le main stage rapidly to, the people is arranged or has other fire protections also can when fire just takes place, sue and labour calmly as the scene, thereby avoid the expansion of the condition of a disaster!
Obviously, fire-fighting exhaust, safety window should be arranged on the position that the fire-fighting disaster takes place the room plane figure easily, in other words, the layout in house should launch according to the setting of fire-fighting exhaust, safety window 1, so that the possibility that disaster enlarges disaster when taking place is reduced to minimum.It must be admitted that, and stack effect requires this fire-fighting exhaust, safety passage preferably to soar up to the sky from the bottom up, and drainage effect is best.But the function in house varies, people's habits and customs vary with each individual again, the special employing when making up passage, often function of use and fire-fighting exhaust, safety window be provided with conflicting, at this moment also can above the room, the passage with lateral arrangement fire-fighting exhaust, safety window 1 be extended to the place that optimum is arranged air flow inlet, though increased local resistance like this, but fire-fighting exhaust, safety window 1 can be arranged in optimum place, and the efficient that has improved fire-fighting exhaust, safety passage greatly is still very worth.
As a same reason, kitchen range hood window can be set on the room wall of corresponding position, subchannel 2 place, in view of the above, the utility model still keeps outside the advantage of simple structure, not only further enlarged fire-fighting exhaust, safety channel function, also played thorough change and disorderly discharged the disordered state of kitchen range hood to corridor, staircase at present, thereby can promote the standardized problem of kitchen range hood, can improve the hygienic conditions of housing construction greatly, improve our general level of the health.
Water can carry boat also can capsized boat, the strong instrument of taming fire is changed into " stack effect " of the sort of terror in current scene of fire in enforcement of the present utility model, reach the positive effect of simple in structure, with low cost, green, environmental protection, low-carbon (LC) simultaneously, opened the building construction security against fire and the sanitary new situation.
Must be pointed out that above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; Change or modify so long as disclose spiritual any being equal to of being done, all fall into the protection domain that this patent comprises according to this patent.
