Description :
A fireproof rolling shutter door, together with a frame that can meet the requirements of fire resistance stability and integrity within a certain period of time, is composed of a curtain plate, a scroll, an electric motor, a guide rail, a bracket, a protective cover, and a control mechanism.Fireproof roller blinds are mainly used for walls that require fire separation, especially for firewalls and fire-resistant partition walls that require large openings for production, use, etc. but cannot be equipped with fire doors for fire separation.Steel fireproof rolling shutter
A rolling shutter made of steel materials for curtains, guide rails, seat plates, lintels, boxes, etc., and equipped with a door rolling machine and control box, which can meet the requirements of fire integrity.Inorganic fiber composite fireproof rolling shutterA roller blind made of inorganic fiber materials for the curtain surface, steel materials for the clamp plate, guide rail, seat plate, lintel, box body, etc., and equipped with a rolling door machine and control box, which can meet the requirements of fire integrity.Special grade fireproof roller shutterA rolling shutter made of steel or inorganic fiber materials as the curtain surface, steel materials as the guide rail, seat plate, clamp plate, door lintel, box body, etc., and equipped with a rolling door machine and control box, which can meet the requirements of fire integrity, thermal insulation, and smoke prevention performance.
1、 Limit the number of fire-resistant rolling shutters in fire compartments:The more fireproof rolling shutters in the same fire compartment, the lower the overall reliability of the fireproof rolling shutters. Therefore, the fireproof rolling shutters in the fire compartment should be controlled
For places with special needs, multiple fireproof rolling shutters should be installed, and other measures should be taken to enhance their reliability or conduct performance evaluations to achieve equivalent fire safety levels.2、 Limit the application scope of fire-resistant rolling shutters:The current technical specifications allow for the replacement of firewalls with fire-resistant rolling shutters, except for those in warehouses that cannot be replaced by fire-resistant rolling shutters. Given the widespread problem of low reliability of fireproof rolling shutters, it is recommended to revise the technical specifications and provisions related to the application of fireproof rolling shutters. It should be clarified that fireproof rolling shutters cannot replace firewalls, and strict regulations should be imposed on the application locations and parts of fireproof rolling shutters.3、 Add fire-resistant rolling shutter anti blocking alarm function:It is common for fire-resistant rolling shutters to be obstructed by objects during use, accounting for 40% of the causes of malfunctions. Although there are personnel patrols in management measures and signs stating "Do not stack items under the shutter" on site, due to the dynamic flow of people and logistics, fire-resistant rolling shutters may be obstructed by objects at any time. Once a fire occurs at this time, the fire-resistant rolling shutter cannot be effectively lowered and cannot provide fire separation. For such an important fault link, measures should be strengthened to prevent and alert in advance. It is recommended to install an anti obstruction alarm device on the fireproof rolling shutter, which will sound an alarm as long as there is an object under the fireproof rolling shutter. The alarm device is equipped with a 5-second delay. When people and objects pass under the rolling shutter within 5 seconds, it will not sound an alarm. The obstruction detection method can use infrared detection. After research and finalization, the alarm device will be included in the technical specifications for fireproof rolling shutter products. If this technical measure can be implemented, it will significantly improve the reliability of the fireproof rolling shutter.
