Construction requirements and appearance requirements of fire-resistant rolling shutter doors, fire-resistant rolling shutter door prices

The construction requirements for an inorganic cloth fire-proof rolling shutter door are based on the inorganic cloth-based fire-proof rolling shutter atlas. Fireproof rolling shutter door price
The second fire rolling shutter door should comply with the "Fireproof rolling shutter door"
Fireproof, smokeproof, windproof and anti-theft, and can be used in conjunction with the temperature-sensing smoke alarm system.
It should be divided into one step and two steps. In case of fire, the door body can be automatically controlled to drop, and it can stop for ~ minutes (from the ground for emergency evacuation of personnel), and then the door body continues to drop and close to prevent fireworks from escaping.< br/> There is an emergency lifting button inside and outside the door. If necessary, the door can be raised to the stop position to continue evacuating people. The door will automatically fall and close according to the determined delay time.

Please contact the fire protection center The control room is linked to achieve total control, and has manual and automatic opening and closing functions.
Appearance requirements for three-inorganic cloth fire-proof rolling shutter doors
The surface of the metal parts of the fire-proof rolling shutter should not have cracks, pits and obvious concave and convex hammer marks Burr holes and other defects. The surface should be treated with anti-rust treatment, and the coating should be even and there should be no peeling or bleeding.
The surface of the fire-proof roller shutter inorganic fiber composite curtain should not have tears, corners, holes, holes, tilt jumps Defects such as broken threads, obvious uneven density of warp and weft yarns, and color differences. The splints should be straight and the clamping should be firm. The warp direction of the base fabric should be the direction of stress on the curtain surface, and the curtain surface should be beautiful, straight, and clean.
Relatively There should be no burrs in the moving parts during cutting, bending, punching, drilling and other processing.
There should be no misalignment at the assembly and splicing of each component.
The welding joint should be firm, the appearance should be smooth, and there should be no slag inclusions or leaks Loose welding and other phenomena.
All fasteners must be tight and should not be loose.
Four material requirements for inorganic cloth fire-proof rolling shutter doors
Various raw materials used in the main parts of fire-proof rolling shutters should Comply with the requirements of the corresponding national standards or industry standards.
The thickness of the plywood, the thickness of the seat plate, and the thickness of the buried guide rail.
The decorative fabric or base fabric of the inorganic fiber composite fireproof roller shutter surface should be able to withstand the temperature of 1℃ It will not cause brittleness under certain conditions and should maintain a certain degree of elasticity and should not stick to +°C.
The combustion performance of the inorganic fiber composite fireproof roller shutter curtain surface decoration fabric should not be lower than the requirements of grade (textile fabric) The burning performance of the fabric should not be lower than the requirements of grade 1.
The breaking strength of various textiles used in the surface of inorganic fiber composite fire-proof roller shutters at room temperature should not be lower than / in the warp direction and should not be lower than / in the weft direction.
Five inorganic cloth fire-proof rolling shutter doors have smooth operation performance
The curtain surface should run smoothly in the guide rail, and there should be no derailment or obvious tilt. The two curtain surfaces of the double-curtain roller shutter should rise and fall at the same time. The height difference between the curtain surfaces should not be greater than.
The average noise during the opening and closing operation of the fire-resistant roller shutter should not be greater than.
The operating speed of the electric opening and closing of the vertical roller shutter should be /~. Its own weight decreases The speed should not be greater than /. The operating speed of the electric opening and closing of the lateral roller shutters should not be less than /. The operating speed of the electric opening and closing of the horizontal roller shutters should be /~/.
Fireproof rollers installed at the evacuation passages The curtain should have two-step closing performance.
The fire-proof roller shutter should be equipped with a temperature-controlled release device. When the temperature around the temperature-sensing element of the release device reaches ±°C, the release device will operate, and the roller shutter should drop and close according to its own weight.

Dimensional tolerances of the main components of six inorganic cloth fire-proof rolling shutter doors
The guide rail groove is deep and the groove is wide.
Technical indicators of seven-machine fabric fire-proof rolling shutter door
Fire protection grade, fire resistance limit hours
Wind pressure resistance/㎡).
When the pressure difference on both sides of the smoke-proof curtain is different, the amount of smoke leakage under standard conditions should not be greater than (㎡?).
Eight Technical Requirements for Installation of Inorganic Fabric Fire-proof Rolling Shutter Doors
The number of seams on the curtain surface of inorganic fabric fire-proof rolling shutter doors should not exceed 1 per meter, and the joints should avoid overlapping. The stress-bearing seams on the curtain surface should be sewn with double threads, and the overlap of the splicing seams should not be less than. Non-stress seams can be sewn with single thread, and the overlap amount at the splicing seam should not be less than 100%.
The inorganic fiber composite curtain surface should be provided with high-temperature stainless steel wires at certain intervals along the weft direction of the curtain fabric (the ropes should bear the weight of the curtain surface and set up splints along the cord warp direction to ensure the overall strength of the curtain surface. The spacing between the splints should be For.
In addition to plywood, windproof hooks should be installed at both ends of the inorganic fiber composite curtain surface.
When the width of the opening is <, the embedded depth of each end of the guide rail should be > The sliding surface of the guide rail should be smooth and flat. The straight rollers should be smooth and smooth when running in the guide rail, and there should be no collision or impact.
The control box for fire-proof rolling shutters should be a stereotyped supporting product that has passed the inspection by the national fire inspection agency.
Fire prevention The rolling door machine for rolling shutters should be a stereotyped supporting product that has passed the test of the national fire inspection agency. Fireproof rolling shutter door price
