Abstract
The utility model relates to an automatic smoke-blocking suspended wall which belongs to a fire product of proof fume exhaustion aspect, which is an indispensable device in tall buildings on smoke prevention and fume exhaustion. The utility model overcomes the defect that a specially arranged girder or a fire wall divides the smoke zone. A solenoid switch is controlled by two ion smoke alarms through an ' AND ' mode, so the suspended wall can fall down slowly to block smoke. A manual switch is arranged meanwhile to reach the aim of blocking smoke when fire.
Description
The utility model is the fire product of a kind of anti-smoke evacuation aspect.
In current highrise building is built, deficiency is paid attention in anti-smoke evacuation in the fire, general both at home and abroad statistics is thought, sootiness causes death the people and accounts for 70% of fire fatality number in the fire, to stopping of flue gas in the fire, general beam or the fire wall that adopts special setting hinders cigarette in hall and corridor.The deficiencies in the prior art part be 1. under construction the corridor and the hall in adopt beam and fire wall to carry out the division of smoke bay, make that the pipeline in hall and corridor furred ceiling can not be walked; 2. in highrise building because floor height is restricted, the beam used of retaining cigarette is set makes that personnel are current and be restricted.A few countries such as Japan have been produced some smoke-proof pendant walls in recent years, residence is made up of frame, the wall that hangs down, motor mechanism, its thickness is 20 centimetres, and its weak point is 1. to be used in the vertical wall in the corridor owing to be subjected to the restriction of frame, and making hangs down has certain slit between wall limit and the wall.2. adopt motor mechanism to start vertical wall and made the wall that hangs down that thicker thickness be arranged, taken the effective ceiling void.3. the wall that hangs down does not have right-angle side, can't hang ceiling material.4. owing to do not feel the cigarette device, the action of the wall that hangs down can't be controlled automatically.
The purpose of this utility model is to avoid weak point of the prior art, provides a kind of and both can guarantee that the pipeline in the ceiling void walked, and stops the climing Smoke prevention district of crossing of flue gas, can make People's Bank of China's current automatic smoke-proof pendant wall that is not restricted in the corridor again.
So array structure just can be realized the purpose of utility model under adopting.The automatic catch cigarette hangs down wall system by movable wall, the matrix frid of hanging down, releasing device (manually reaching motor switch), and buffer, sniffer are formed.It can level be hung on the roof, the vertical wall of its assembling position is fixed on the matrix frid with hinge, and at the opening direction device releasing device of wall and matrix frid that hangs down, a buffering air pressure is installed between vertical wall and matrix frid is discharged pull bar, with lead probe and releasing device are coupled together simultaneously.
Figure one, the vertical wall construction schematic diagram of automatic catch cigarette
Below in conjunction with accompanying drawing, embodiment content of the present utility model is described in further detail.
Among the figure: 1 smoke alarm; 2 matrix frids; 3 right-angle sides; Gear cigarette limit, 4 right angles 5 pressure buffer positioners; 6 releasing devices; 7 wired hose hand switches; 8 vertical walls.
By the Ion Smoke Sensor detector (1) of two III levels with " with " mode is connected, certain control signal by pressure and electric current is provided, respectively fold the right-angle side (3) of one fixed width with slot type fixed head (2) trough rim of 6 wide cm thicks with the aisle, be used for hanging suspended ceiling decoration material, on the in-built gear cigarette limit (4), right angle of establishing of matrix frid, alter cigarette in order to be blocked in hinge seam place, be fixed on the gear cigarette limit, right angle with the vertical wall (8) of hinge with 〉=50 centimetres high, make it can be from horizontally rotating vertically, an air pressure piston type buffering releasing device (5) that arranged certain release time is installed between hang down wall and matrix frid, and to make vertical wall drop to vertical time from level be 10～30 seconds, between vertical wall and matrix frid, electromagnetic release switch is installed, (6) namely can automatically pull open latch after it receives the signal of telecommunication of certain voltage and electric current makes the wall that hangs down fall to stoping spreading of flue gas, make it reach the purpose of smoke bay, other establishes one and overlaps the hand switch that can install within the specific limits, and (7) make automatic smoke-blocking suspension wall reach the purpose of utility model.
The utility model compared with prior art has following advantages:
1. existing product is owing to be subjected to the impact of frame, and is not tight with corridor two abutment wall shutoff, realizes that the utility model does not then have side frame, and movable wall and the corridor of hanging down be with wide, and at both sides installation sealing strip.
2. substitute motor mechanism with electromagnetic mechanism and make designs simplification, make the product thickness attenuate, run-though space strengthens in the furred ceiling.
3. hand gear reaches and can start the wall action of hanging down under the non-transformer situation.
Claims (4)
1, a kind of vertical wall device of automatic catch cigarette that is specially adapted to the anti-smoke evacuation of fire-fighting, it comprises: the wall that hangs down, matrix frid, releasing device, positioning tie bar; The wall that hangs down is fixed on the matrix frid with hinge, and at the opening direction device releasing device of wall and matrix frid that hangs down, a positioning tie bar is installed between vertical wall and matrix frid; The Ion Smoke Sensor probe (1) that it is characterized in that two III utmost points with " with " mode is connected.
2, as claims 1 described automatic smoke-proof pendant wall, it is characterized in that piston type air buffering releasing device (5), adjust the pressure of gas in the cylinder body, make to discharge to reach the regular hour.
3, automatic smoke-proof pendant wall as claimed in claim 1 is characterized in that retaining cigarette limit (4), device one right angle on the matrix frid.
4, automatic smoke-proof pendant wall as claimed in claim 1 is characterized in that the concave groove edges of boards respectively go out the right-angle side of certain width (3).
