Standard specification for installation of fire shutter doors

1. Construction requirements for inorganic fabric fire shutter doors: According to the atlas of inorganic fabric fire shutter doors.

2. Fire shutter doors shall comply with GB14102-2008 "Fire shutters": 1. Fireproof, smokeproof, windproof, and burglarproof, and can be used in conjunction with temperature and smoke alarm systems. 2. It should be divided into one-step drop and two-step drop: in case of fire, it can automatically control the door body to drop, and can stop for 1 to 10 minutes (1.8m from the ground) for emergency evacuation, and then the door body continues to drop and close to prevent The fireworks went out. 3. There are emergency lifting buttons inside and outside the door. If necessary, the door can be raised to the stop position to continue evacuating people, and the door will automatically drop and close according to the determined delay time. 4. It should be linked with the fire central control room to realize the overall control, and also have manual and automatic opening and closing functions.

3. Appearance requirements for inorganic fabric fire shutter doors: 1. There should be no cracks, pits, obvious bumps, hammer marks, burrs, holes and other defects on the surface of the metal lower part of the fire shutter. Its surface should be treated with anti-rust treatment, and the coating and plating should be uniform without stripping or flowing. 2. The inorganic fiber composite curtain surface of the fireproof roller shutter should not have defects such as tearing, missing corners, gouging, holes, tilting, jumping wires, broken wires, obvious uneven density of warp and weft yarns, and color difference; the plywood should be straight and clamped It should be firm, and the warp direction of the base fabric should be the stress direction of the curtain surface, and the curtain surface should be beautiful, straight and clean. 3. Relatively moving parts should not have burrs in cutting, bending, punching and drilling. 4. There should be no misalignment in the assembly and splicing of each lower part. 5. The welding place should be firm, the appearance should be flat, and there should be no slag inclusion, missing welding, looseness, etc. 6. All fasteners must be tight and there should be no looseness.

4. Material requirements for inorganic fabric fire shutter doors: 1. Various raw materials used for the main components of fire shutters should comply with the relevant national standards or industry standards. 2. The thickness of the splint is ≥3.0mm, the thickness of the seat plate is ≥3.0mm, and the thickness of the buried guide rail is ≥1.5mm. 3. The decorative fabric or base fabric on the surface of the inorganic fiber composite fireproof roller shutter should not be brittle under the condition of -20°C and should maintain a certain degree of elasticity; it should not stick under the condition of +50°C. 4. The combustion performance of the inorganic fiber composite fireproof curtain surface decoration cloth should not be lower than the requirements of GB 8624-1997B1 (textile); the combustion performance of the base fabric should not be lower than the requirements of GB 8624-1997A grade. 5. The breaking strength of various textiles used for the surface of inorganic fiber composite fireproof roller shutters at room temperature should not be lower than 600 N/5cm in the warp direction, and 300 N/5cm in the weft direction.

5. Dimensional tolerances of the main parts of the inorganic cloth fireproof rolling door: 1. The depth of the guide rail groove is ±2.0mm, and the groove width is ±2.0mm. 6. Technical requirements for the installation of inorganic fabric fireproof rolling shutter doors: 1. The number of joints on the curtain surface of inorganic fabric fireproof rolling shutter doors should not exceed 3 per meter, and the joints should avoid overlapping. The stress seams on the curtain surface should be sewn with double threads, and the overlap of the splicing seams should not be less than 20mm. Non-stress seams can be sewn with a single thread, and the overlap at the splicing seam should not be less than 10 mm. 2. The inorganic fiber composite curtain surface should be provided with high temperature resistant stainless steel wires (ropes) at regular intervals along the weft direction of the curtain fabric to bear the weight of the curtain surface; splints should be arranged along the curtain fabric meridian direction to ensure the overall strength of the curtain surface. It should be 300mm-500mm. 3. In addition to the plywood on the surface of the inorganic fiber composite curtain, windproof hooks should be installed at both ends. 4. When the width of the hole is ≥3000mm and <5000mm, the embedded depth of each end of the guide rail should be more than 50mm; the sliding surface of the guide rail should be smooth and straight; the curtain surface and the roller should be stable and smooth when running in the guide rail, and there should be no collision and impact Phenomenon. 5. The rolling door machine for fire shutters should be a finalized supporting product that has passed the inspection of the national fire inspection agency. 6. The control box for fire shutters should be a finalized supporting product that has passed the inspection of the national fire inspection agency. 7. Smoke-proof devices should be installed in the guide rails of the fire-proof and smoke-proof roller shutters, and the materials used for the smoke-proof devices should be non-combustible or difficult-to-combustible materials. 8. Smoke-proof devices should be installed in the eyebrows of the fire-proof and smoke-proof roller shutters, and the materials used for the smoke-proof devices should be non-combustible or difficult-to-combustible materials.
