Abstract
The invention discloses an open space firefighting and smoke exhaust structure of a high-rise office building with curtain walls. The open space firefighting and smoke exhaust structure has the advantages that firefighting and smoke exhaust requirements of indoor open office spaces can be met on the premise that the floor heights of the high-rise office building and the manufacturing costs of the curtain walls are not increased, and vertical shafts of standard floors of the office building are used as indoor smoke exhaust outlets, and are positioned according to the requirement that the distances from the farthermost indoor points to smoke exhaust outlets are shorter than 30 m; horizontal air ducts which are originally arranged between the smoke exhaust outlets and the smoke exhaust vertical shafts can be omitted, accordingly, the floor heights of the standard floors can be reduced, and the problem of difficulty in arranging natural smoke exhaust windows in existing curtain walls can be solved.
Description
Technical field
The present invention relates to a kind of high-rise curtain wall office building wide open space fire control smoke exhausting structure, belong to building curtain wall technical field.
Background technology
Since 2014 editions " Code for fire protection design of buildings " GB50016-2014 perform, the fire control smoke exhausting opening wide working space being greater than 100 square metres in Tall Office Buildings has become the common difficulty that everybody runs into, because clear stipulaties top hinged window in new edition specification can not be used as natural draught system, this just means that top hinged window conventional is in the past used as this Normal practice of fire-fighting natural draught system and is nowadays denied.Other natural draught system mode cannot adopt owing to all there is the defect of himself in actual items.Such as casement window opening inwards, can affect the use of the interior space after unlatching, and " inside holding " this structural form can cause the percolating water of curtain wall system; Although bottom hinged window is optimal fume exhausting type, but run into sleet sky after opening at ordinary times and can bring again inconvenience in use, although can increase sleet induction module in curtain wall system outside, opening door-leaf is closed after can automatically responding to sleet voluntarily, but this adds construction costs again virtually.If transfer to adopt conventional mechanical smoke extraction, a series of ways such as indoor fire control smoke exhausting airduct can propose new requirement to the floor height of building again, additionally can increase construction costs thus.Therefore the fire control smoke exhausting how solving office tower wide open space becomes a thorny new problem.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, a kind of high-rise curtain wall office building wide open space fire control smoke exhausting structure is provided, solve difficult problem curtain wall being offered natural smoke exhaust windows, facade facade effect can be ensured, curtain wall cost can be reduced again.
For solving the problems of the technologies described above, the invention provides a kind of high-rise curtain wall office building wide open space fire control smoke exhausting structure, it is characterized in that, smoke evacuation point position is set in the side in the aisle of the close indoor wide open space of every layer, each smoke evacuation site setting smoke shaft, the smoke shaft of each layer is through and pass to roof, is connected with the fume extractor being arranged on layer top.
The sidewall furred ceiling of every layer of smoke shaft arranges indoor exhaust wind mouth with lower portion.
Described indoor exhaust wind mouth is louver structure.
Indoor exhaust wind open area is directly proportional to indoor wide open space size.
Indoor exhaust wind open area is no more than 1.5 square metres.
The smoke shaft area at each smoke evacuation point position place is no more than 1 square metre.
One or more smoke evacuation point position is set in every layer.
Be not more than 30 meters according to each smoke shaft service radius of every layer, smoke extraction area is not more than 500 square metres, a smoke evacuation point position is set.
The beneficial effect that the present invention reaches:
1, reduce facade to window, both ensure that facade facade effect, additionally reduced curtain wall cost.
2, the floor height of highrise building is saved.
3, horizontal smoke exhaust pipe is saved.
4, difficult problem curtain wall being offered natural smoke exhaust windows is solved.
Under the prerequisite that building floor height limits by economic factor, the fire control smoke exhausting opening wide working space in Tall Office Buildings adopts mechanical smoke extraction mode, under the prerequisite not increasing floor height, saving construction cost, according to the high plane characteristic of highrise building typical floor similarity with vertically superpose advantage, the ingenious regulation utilized in smoke controlling specification, by means of only arranging smoke shaft, the fire control smoke exhausting of all floor wide open spaces in highrise building just can be solved.
Accompanying drawing explanation
Fig. 1 is smoke shaft layout schematic diagram;
Fig. 2 is smoke shaft generalized section;
Fig. 3 is smoke shaft blinds schematic diagram;
1. indoor wide open space, 2. aisle, 3. smoke shafts, 4. indoor exhaust wind mouth, 5. fume extractor in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As Figure 1-3, high-rise curtain wall office building wide open space fire control smoke exhausting structure of the present invention, according to the area requirements of using function and smoke bay in the typical floor plan of Tall Office Buildings, in the indoor wide open space 1 of every layer, the side in aisle 2 arranges smoke evacuation point position, each site setting smoke shaft 3, each layer smoke shaft is through and pass to roof, and be connected with the outdoor fume extractor 5 being arranged on layer top, indoor smoke shaft 3 arranges indoor exhaust wind mouth 4 near furred ceiling.Shaft area is different according to the size of wide open space, the most about 1 square meter.
Arrange smoke evacuation blinds below shaft wall furred ceiling, blinds area is determined according to room-size, the most about 1.5 square meters.
The present invention is ingenious utilizes smoke shaft, 30 meters are not more than according to smoke shaft every layer, each smoke vent opening service radius, smoke extraction area is not more than the requirement of 500 square meters, in the plane of typical floor, some smoke evacuation point positions can be set according to this code requirement, each some position can arrange smoke shaft, arranges smoke evacuation blinds below smoke shaft sidewall furred ceiling.This way arranges repetitive rate high according to compact, the vertical floor level of plane figure of Tall Office Buildings, optimize conventional mechanical fume exhausting type, eliminate conventional horizontal smoke exhaust pipe, smoke vent opening is set directly on vertical shaft, gives full play to the service efficiency of smoke shaft.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
