Abstract
The utility model relates to a stair handrail-based air supplying escape system under a fire accident condition. The air supplying escape system comprises a tubular stair handrail integrally connected in a staircase; the end part of the tubular stair handrail is connected with an air supplying pipeline connected with a fan; the tubular stair handrail is provided with vents. The stair handrail-based air supplying escape system under the fire accident condition is simple in structure, reasonable in design and low in cost, by performing simple reconstruction on the existing integrally connected tubular stair handrail in the staircase, clean air can be conveyed by the tubular stair handrail to be supplied to escape personnel for breathing, and the aim that personnel in the staircase are not invaded by the smoke can be realized.
Description
Technical field
?the utility model relates to the air-supply escape system based on balustrade under a kind of fire situation.
Background technology
In reality, once building breaking out of fire, volume of smoke can be along with " stack effect " be along upwards diffusion of staircase, although can consider closed stair or smoke prevention staircase in architectural design, install labeled door, positive pressure fan etc. additional, but can not fundamentally guarantee that flue gas does not enter staircase.Due under fire situation, personnel's evacuation escape is the first instinct, especially the personnel that highrise building occupy fire genetic horizon top must evacuate downwards by staircase, evacuating personnel direction forms convection current with the flue gas that upwards pours in diffusion along staircase, increased the weight of the possibility that personnel suck toxic gas, from the statistics of a large amount of fire casualtiess, be not difficult to find, staircase remains flue gas to the maximum place of evacuating personnel escape infringement.The personnel that how to solve are not become distinct issues in the scene of a fire by flue gas infringement at staircase.
Utility model content
In order to overcome prior art deficiency, the utility model provides the air-supply escape system based on balustrade under fire situation.The utility model is simple in structure, reasonable in design, by the balustrade that existing floor gap one is connected, simply transforms, and can the personnel that realize well by flue gas, not encroached at staircase.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Air-supply escape system based on balustrade under fire situation, comprises the tubulose balustrade that floor gap one connects, and the end of described tubulose balustrade is connected with air supply duct, and air supply duct is connected with blower fan, and tubulose balustrade is provided with gravity vent.
When fire occurs, personnel evacuate downwards by staircase, evacuating personnel direction forms convection current with the flue gas that upwards pours in diffusion along staircase, now blower fan is sent to tubulose balustrade by air supply duct by pure air, clean air flows in the pipeline of tubulose balustrade, by gravity vent, flow out, personnel can breathe clean air in the ventilation on tubulose balustrade, have greatly reduced the probability of death by suffocation.
If the balustrade non-tubular shape structure in existing building, can add ventilating duct at balustrade place, ventilating duct is connected with blower fan by air supply duct, and ventilating duct is provided with gravity vent.
Preferably, the end that described tubulose balustrade is positioned at the end of top layer or is positioned at bottom is connected with air supply duct.
Preferably, the end that described tubulose balustrade is positioned at top layer is connected with the first blower fan by the first air supply duct, and the end that tubulose balustrade is positioned at bottom is connected with the second blower fan by the second air supply duct.
Floor upper strata and basement install respectively first, second blower fan additional, have improved the conveying capacity of pure air in tubulose balustrade.
Preferably, described gravity vent is arranged on the turning point of the stair bench of tubulose balustrade.
Preferably, described tubulose balustrade is made of metal.
First-selected tubulose balustrade is metal material, and as stainless steel etc., this kind of material also used in majority building.Not flammability, continuity, workability that it is good, function of the present utility model is realized becomes possibility.
The utility model compared with prior art, tool has the following advantages: simple in structure, reasonable in design, with low cost, by the tubulose balustrade that existing floor gap one is connected, simply transform, can carry pure air to breathe for escape personnel by tubulose balustrade, can the personnel that realize well by flue gas, do not encroached at staircase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, air-supply escape system based on balustrade under fire situation, comprise the tubulose balustrade 4 that 3 one of floor connect, the end that described tubulose balustrade 4 is positioned at top layer 1 is connected with the first blower fan 6 by the first air supply duct 7, the end that tubulose balustrade 4 is positioned at bottom 2 is connected with the second blower fan 9 by the second air supply duct 8, tubulose balustrade 4 is provided with gravity vent 5, and described gravity vent 5 is arranged on the turning point of the stair bench of tubulose balustrade 4.
When fire occurs, personnel evacuate downwards by staircase, evacuating personnel direction forms convection current with the flue gas that upwards pours in diffusion along staircase, now the first blower fan 6 and the second blower fan 9 are sent to tubulose balustrade 4 by the first air supply duct 7 and the second air supply duct 8 by pure air respectively, clean air is interior mobile at tubulose balustrade 4, by gravity vent 5, flow out, personnel can breathe clean air in the ventilation 5 on tubulose balustrade 4, have greatly reduced the probability of death by suffocation.
