Abstract
The utility model provides a smoke prevention device for a square basement, which comprises a smoke prevention stair hall communicated with each floor of the square basement and directly connected with the ground surface, wherein a front room is arranged between the smoke prevention stair hall and each floor of the square basement, the front room is isolated from the smoke prevention stair hall and the basement through an isolating door respectively, the front room on each floor of the square basement is communicated with an air intake shaft, a blower room is arranged between the front room on the first floor of the square basement and the ground surface, a boosting fan is arranged inside the blower room, and the boosting fan is communicated with the front room on each floor of the square basement through a pipe. In the smoke prevention device for the square basement, the smoke prevention stair hall, the front rooms, the air intake shaft and the booting air supply system are arranged reasonably, so that the smoke prevention device for the square basement can not affect the landscape of a square on the ground.
Description
Technical field
The utility model relates to building field, especially the Smoke prevention device of the basement below the square.
Background technology
Staircase is the unique fire escape of building after on fire, cup is set and will considers that at cup Smoke prevention is exactly full of smokely to advance staircase and cause fire escape to be obstructed in order further to prevent.For square basement (garage, underground commerce square etc.), some does not possess the smoke and the cup thereof of the basement of natural draught system condition, at present common way is to establish forced draught blower at smoke or its cup top to carry out pressure air blowing through piping, because the layout between the basement smoke, cup, downcast, pressure air blowing equipment pipe is reasonable inadequately, make the landscape impact of wide over the ground of Smoke prevention device of basement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of square basement fume-resisting system measure is set, rationally distributed between basement smoke, cup, downcast, the pressure air blowing system makes the view of wide over the ground of Smoke prevention device of basement can not impact.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of square basement Smoke prevention device, comprise the smoke that is communicated with every layer of basement and straight-through ground, be provided with cup between described smoke and every layer of basement, described cup is isolated by isolating door and described smoke and basement respectively, and the cup of every layer of basement is communicated with downcast; Be provided with Ventilator Room between the cup of B1 basement and the ground, be provided with booster fan in the described Ventilator Room, described booster fan is communicated with the cup of each layer basement by pipeline.In the basement Smoke prevention device of the present utility model, rationally distributed between basement smoke, cup, downcast, the pressure air blowing system makes the view of wide over the ground of Smoke prevention device of basement can not impact.
As improvement, described downcast is located at the top of each layer basement cup, and downcast one side combines with described smoke guardrail.
As improvement, behind the straight-through ground 300mm of described downcast, its side wall is established the blinds air intake, perhaps directly at the staircase side wall air intake that opens wide, reduces by wide over the ground landscape impact.
As improvement, described downcast top is provided with ornament, as planting greenbelt or moulding design.
The beneficial effect that the utility model is compared with prior art brought is:
Establish an interlayer as the pressure air blowing machine room above cup, forced draught blower is sent into each layer cup by vertical tube; Adjacent smoke place, cup top establishes downcast, combines with the staircase guardrail, and beautifies the downcast top with greening or design; Rationally distributed between basement smoke, cup, downcast, the pressure air blowing system makes the view of wide over the ground of Smoke prevention device of basement can not impact.
Description of drawings
Fig. 1 is the utility model sectional view.
Fig. 2 is a first floor smoke floor map.
Fig. 3 is a B1 basement floor map.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of square basement Smoke prevention device, comprise the smoke 9 that is communicated with every layer of basement and straight-through ground, be provided with cup 4 between described smoke 9 and every layer of basement, described cup 4 is isolated by isolating door 41 and described smoke 9 and basement respectively, and the cup 4 of every layer of basement is communicated with downcast 1.Be provided with Ventilator Room 3 between the cup 4 of B1 basement and the ground 2, be provided with booster fan 5 in the described Ventilator Room 3, described booster fan 5 is communicated with the air outlet 7 of the cup 4 of each layer basement by vertical pipeline 6.Shown in Fig. 2,3, described downcast 1 is located at the top of each layer basement cup 4, and downcast 1 one sides combine with described smoke 9 guardrails.Behind the described downcast 1 straight-through ground 300mm, its side wall is established blinds air intake 11, and described downcast 1 top is provided with greenbelt 8.
Basement below a lot of squares is equipped with the smoke 9 and the cup 4 on straight-through ground, smoke 9 is the straight-through ground of open type, its cup 4 needs the pressurization Smoke prevention, because of all there is earthing on general square, cup 4 parts are accomplished with earthing flat, above cup 4, establish an interlayer as the pressure air blowing machine room, if forced draught blower is sent into each layer cup 4 by vertical tube, adjacent smoke 9 places, cup 4 tops establish downcast 1, combine with smoke 9 guardrails, and with the greening or design beautify downcast 1 top, behind downcast 1 300mm above ground level, its side wall is established blinds air intake 11, perhaps directly at the staircase side wall air intake that opens wide, reduces by wide over the ground landscape impact.
In the basement Smoke prevention device of the present utility model, rationally distributed between basement smoke 9, cup 4, downcast 1, the pressure air blowing system 3,5 makes the view of wide over the ground of Smoke prevention device of basement can not impact.
