Classification and use scope of fire-proof rolling shutter doors and local settings of fire-proof rolling shutter doors, wholesale of fire-proof rolling shutter doors

The fire shutter door functions as a horizontal fire separation in the same way as the fire wall. It consists of a curtain plate, seat plate, guide rail support, reel box, control box, rolling door machine limiter, door lintel manual quick release switch device, button switch and safety device, etc. It consists of three parts and is generally installed in places where it is inconvenient to use firewall separation. For example, open elevator halls, escalators, large business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings where fireproof doors and windows cannot be used. Fire-proof rolling shutter doors have been widely used in fire-proof separation in construction projects. Fireproof rolling shutter door wholesale
Fireproof rolling shutter classification
According to the opening direction, it can be divided into two types: top roll and side roll.
According to the installation form, there are two types: wall-in-wall and side-wall (or inside the hole and outside the hole).
According to material, it can be divided into steel, composite, inorganic, etc.
There is no national standard for the classification of fireproof performance of fireproof roller shutters. In the general technical conditions for steel fireproof roller shutters, ordinary steel fireproof roller shutters are divided into
grades, fire resistance time
grades, fire resistance time
Composite steel fire-proof rolling shutters are divided into
grades, fire-resistant time
grades, fire-resistant time fire rolling shutter doors wholesale
However, the national standard does not require the fire resistance performance classification of steel fire-proof rolling shutter doors. The fire resistance test measures the temperature rise of the back fire surface, and does not use the temperature rise of the back fire surface as a condition to determine the fire resistance time. In recent years, vapor mist steel fireproof rolling shutters, evaporative vapor mist steel fireproof rolling shutters, etc. have appeared on the market. , according to the requirements of high regulations, when used as a component for fire partition separation, the temperature rise of the back fire surface must be used as the criterion for determining the fire resistance limit. In order to distinguish the classification of fire-resistant roller shutters with fire resistance limits under the above two different judgment conditions, before the national standards for fire-resistant roller shutter classification are promulgated, experts in high-end regulation management recommend that fire resistance tests be conducted according to the national standard fire resistance test methods for doors and roller shutters. , which meet the requirements of various judgment conditions including the temperature rise of the back-fire surface, and the fire resistance limit, are called special-grade fire-resistant rolling shutters. Those that do not use the temperature rise of the back-fire surface as a judgment condition in the fire resistance test are collectively called ordinary fire-proof rolling shutter doors.
Where are fire shutter doors generally installed?
Determined based on the process, in addition to the firewall, the fireproof rolling shutter door should also be equipped with a fireproof rolling shutter if there is no firewall between the two fireproof zones. Generally located in the following locations.
Inspection doors for cable wells, duct wells, exhaust ducts, garbage ducts and other vertical duct wells.
Seal the evacuation stairs, lead to the walkway, close the elevator room, the door leading to the front room and the front room leading to the walkway. Wholesale of fire shutter doors
Standards (such as fire protection codes for high-rise civil building design) or partition doors with special requirements for fire and smoke protection. For example, the partition doors of equipment rooms with fixed fire extinguishing devices attached to high-rise civil buildings (cylinder rooms, foam stations, etc., ventilation and air-conditioning machine rooms, etc.) should use Class A fire doors on the partition walls of basement rooms where people often stay or where there are many combustibles. Doors should use Class A fire doors. Due to limited conditions, fuel and gas boilers, combustible oil-immersed power transformers, combustible oil-filled high-voltage capacitors and switches must be arranged in high-rise buildings. Doors on partition walls of special rooms. Class A fire doors should be used.
Divide fire protection zones and control the fire walls and doors on fire partition walls set up in the building area of the zones. When it is difficult to install fire walls or fire doors in a building, fire shutter doors should be used instead. Must be protected by water curtain. Wholesale of fireproof rolling shutter doors
