Fire shutter door is a kind of fire-proof and heat-insulating facility suitable for large opening in buildings. This product has played a certain role in design and installation. Fire shutter doors are widely used in fire zones of industrial and civil buildings, which can effectively prevent the fire from spreading and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. Technical requirements for fire shutter doors: average vertical speed, 3m, min fire resistance time, 240 minutes; Smoke leakage, 0. 18m? Every minute, electric lifting, automatic locking and manual opening; After the accessory receives the smoke temperature signal, it will automatically land; After receiving the signal from the fire control center, you can land at last or stop at any position. The thickness of main raw materials shall meet the following requirements: part name, material thickness (mm), curtain plate, 2 guide rails ≥3.0 lintel 1.5 box 0.83. Appearance requirements: No cracks, pits, obvious bumps, hammer marks, burrs, holes and other defects are allowed on the surfaces of curtain plates, guide rails, lintels, reels and other parts; Relative motion in cutting, bending, drilling and other processing places, we must deal with burrs.
The assembly and splicing of components or parts are not allowed to be misplaced; The welding place should be firm and flat, and slag inclusion and missing welding are not allowed; The external leakage surface of the parts must be treated with rust prevention, and the coating should be uniform without spots; All fasteners must be tightened and are not allowed to loosen. The average noise of shutter opening and closing and operation shall meet the following requirements: the power of shutter w, KW ≤ 0.4 and the average noise dbw≤500. Main quality requirements: adjacent interlocking curtain plates can rotate flexibly after being connected in series, and cannot fall off when swinging 900; Baffles or anti-channeling mechanisms at both ends of the curtain plate should be firmly assembled. After the curtain plate is assembled, the channeling momentum of the curtain plate shall not be greater than 2mm.
