Description
Technical field
The utility model belongs to the building fire protection member in security against fire field, particularly a kind of power drive, rotation automatically, the cylinder spring shaft of speed-controllable and a kind of vertical (volume) curtain of soft automatic fire prevention retaining cigarette that comprises this cylinder spring shaft of need not.
Background technology
Fire curtain and labeled door have been widely used in the fire separation on building fire protection subregion and elevator cup, staircase, the evacuation aisle as the functional building fire protection member in security against fire field, prevent fire spread.
Fire curtain is applicable to that mineral wool is separated use on the big hole of building.Because its roller shutter machine is by the electric energy transmission, complex structure, it is big to take up room, and factor such as its price is not suitable for doing fire compartmentation and uses on the little hole of building in addition.In addition, when it loses power supply, the speed of hand hoisting is slow, can influence in emergency circumstances evacuating personnel, rescue and escape.The patent utility model the has been arranged method of establishing door in door in large-scale fire curtain upper shed, to satisfy safety evacuation and escape in emergency circumstances, but, still fail to solve effectively the contradictions such as evacuating personnel, escape and price of fire curtain when on the little hole of building, using.
Labeled door is installed in the purpose on interior fire compartmentation of building and elevator cup, staircase, the evacuation aisle merely as the building fire protection member, is the escape way that prevents fire spread and evacuating personnel is provided.Labeled door will play anti-fire action, and one of them essential condition is that can it keep normally off.Facts have proved, be installed in the elevator cup, staircase is evacuated the labeled door on the aisle, in use is difficult to keep normally off.The fire-proof function of unlatching of labeled door for convenience and maintenance closed condition, people design and have installed an automatic door closing device (door closer) on labeled door, pass through automatic door closing device, though labeled door has been realized automatic closing function, but the normally closed type labeled door the normally off that must keep, also hindered natural ventilation, printing opacity and the pedestrian of building under the non-fire condition itself and the barrier free accessibility that article pass in and out.It is preventative fire protection that the normally closed type labeled door is installed under construction, removes this and should not have its usefulness.The probability that normally closed type labeled door runs into fire is ten thousand/, or even 100,000/, 1,000,000/, and elevator cup, staircase, evacuation aisle be as the access way of building, and the frequency that its personnel are current, article flow is 10,000 times of fire probability, more than 100,000 times or even 1,000,000 times.Establish the normally closed type labeled door at above-mentioned position, just mean that people under the safety state of daily no fire, open labeled door everyday, pass through a lot of obstruction all the time, and meeting the emergency that comprises fire incident, it has also hindered people's evacuation speed.In addition, the normally closed type labeled door is located on the public aisle, natural ventilation, the printing opacity of not only influence building, and its shared catch can cause the propagation of infectious disease, influences public health; The door closer-holder of the unsettled labeled door of some quality, its resistance also can make the following unable labeled door of opening of children of 5-6 year, walk out outdoor activities.Therefore, be installed in the functional normally closed type labeled door on elevator cup, staircase and the evacuation aisle, though have the effect that fire preventing spreads, but more be the obstacle that in routine work, life, has brought current inconvenient and carrying article to people, the influence of bringing for the natural ventilation, printing opacity, heat radiation etc. of building itself.According to investigation, people are to being installed in the normally closed type labeled door on the interior elevator cup of buildings such as office, school, hospital, hotel, restaurant, office premises, industrial and mining enterprises, underground building and high-rise residential building, staircase, the evacuation aisle, the obstacle and the worry of bringing for people's routine work, life are much higher than the understanding to fire preventing.Not strong at people's awareness of the importance of fire prevention, under the reality of the lack of knowledge of taking precautions against natural calamities, the normally closed type labeled door that is installed in above-mentioned construction site is difficult to keep normally off, is opened wide mostly, performs practically no function.In the course of time, people have just ignored the effect that is installed in the normally closed type labeled door fire preventing of locating in elevator cup, staircase, evacuation aisle etc.Even considerable people is arranged, know not the normally closed type labeled door that is installed in above-mentioned position is to make what usefulness.After completion of works was checked and accepted through the fire-fighting of fire department, its anti-fire action was ignored by people mostly, and its unfavorable factor has also just become the object of people's worries and the reason of damage, and is that have even destroyed, is removed, and lost the effect of taking precautions against natural calamities of expection.Fire protection regulation according to " fire control law ", " Code for fire protection design of buildings " and " Code for fire protection design of high rise buildings " and related specifications, regulations has constituted fire disaster hidden danger.Because this hidden fire-fighting danger generality and complexity under construction brought great difficulty for the elimination of hidden danger.On economy, effect, real invalid input has not only caused massive losses to economy, has brought serious threat for the people's lives and property safety, has brought numerous potential hidden fire-fighting danger also for structural fire protection safety.
Summary of the invention
