Steel Fire Curtain
The fire screen is located between the auditorium and the stage. Its function is to seal the front desk entrance, cut off the auditorium and the main stage space, and prevent the spread of the fire. Avoid the oxygen in the auditorium being pumped away by the main stage. Fire curtain can block the viewer's sight, calm the viewer's mood and enable them to exit orderly. When a fire accident occurs in the theatre or at the end of each performance, the fire curtain falls and the stage and auditorium are separated into two fire protection areas. In emergencies, the fire curtain falls in place by gravity within 45 seconds. When it is 2.5m away from the main stage, the damping decreases to avoid injury and impact on the stage. An electric lifting device is arranged on the equipment layer, which can electrically control the rise and fall. It can also drop manually.
Fire curtain and fire resistance limit conform to the relevant fire protection regulations of China.
Fire curtain and guidance system can withstand the air pressure difference between auditorium and stage.
Fire curtain transmission is a balanced hoisting system. Hydraulic damping is used in the damping system.
The hoist is equipped with detection devices such as random rope, loose rope, overload and overrun.
● The curtain body is a steel structure frame flled with fire- proof and flame- retardant materials, and can withstand horizontal and vertical forces. The steel plate is painted with fire retardant paint on the stage.
● Winding system, including motor, reducer, double brake, drum and manual release device, etc.
● The damping force and position of the device can be adjusted by releasing the flling damping device.
● Guide rail and sealing device; top sand sealing groove
● A water curtain device is installed in the entrance of the platform lprovided by fire protection specialtyl to spray the curtain body and prolong the fire resistance time of the curtain body.
● Pulley assembly;
● Balance weight, balance weight frame guide ril and guard net;
● Wire rope and accessories.
● The upper and both sides of the curtain body exceed 0.5m of the stage entrance. Operating guideways are arranged on both sides of the fire curtain. Close encapsulation devices are installed around the curtain body and the building wall, so that when the fire curtain is in the descending position, smoke and fire can be effectively sealed.
● Fire curtain is equipped with warning lamp and buzzer so as to indicate safety when the curtain body is running. and the buzzer can close nearby.
● The local control panel with liting. descending, and emergency stop buttons can be operated in situ, and the manual device for releasing the curtain body descending directly can be used.
