According to the "Code for Design of Theater Buildings":
The fire curtain at the entrance is a safety and fire protection door that can separate the audience hall and the main stage space, preventing the spread of fire and smoke;
Block the audience's line of sight, stabilize their emotions, and enable them to exit in an orderly manner.
1. Overview of Fire Curtain
1 A fire curtain is installed at the entrance between the audience hall and the stage, which is actually a movable fire protection partition. When a fire occurs in the theater
At the end of each performance, the fireproof curtain falls and separates the stage and audience hall into two fireproof areas. In emergency situations, fire curtains
Within 4 5 seconds, descend to the desired position by gravity (closing the stage opening) * When the lower edge of the screen is attached to the stage surface, the damping device will automatically be activated to reduce the screen weight
The deceleration time for the descent of the vehicle shall not be less than 10 seconds A sealing device is installed around the curtain and between the building curtain to ensure that the fire curtain is in the descending position
When sealing smoke and fire effectively, the fire resistance limit of the fire curtain should comply with international standards and relevant fire prevention regulations in China.
1 The fire curtain consists of a curtain body, guide rails, counterweights, driving devices, hoisting systems, damping devices, protective devices, sensors, etc. have
Body size:
-The curtain is a steel structure frame with an outer steel plate and an inner layer filled with fire-resistant and flame-retardant materials.
The winch system consists of an electric motor, a reducer, a brake, a drum, a mechanical manual release device, etc.
Release the damping force of the descending damping device and adjust the damping position.
Guide rails and sealing devices Pulley assembly, balance child and guide rail Steel wire ropes and accessories*
1 3. The fire curtain can be electrically controlled to rise and fall, or manually lowered. The design guarantee of the damping mechanism and driving device of the fire curtain in the theater
In the event of a fire (even if there is a complete power outage), the fire curtain can still be closed by its own weight damping.
