Fire shutter as with firewall role played bounding horizontal zones separated by curtains Board, plank, guides, bearings, spool, Cabinet, control box, shutter, restrictor, doorway, manual speed drop switchgear, button switch and device, such as the 13-part, common installation in the inconvenience of parts, separated by a firewall. Example: open the elevator, escalator, Department store of the spacious hall, exhibition floor exhibition halls and buildings of the cave is large and cannot be used for fire doors and Windows. Fire shutter in architectural engineering, the fireproofing won the broad application. First, fire shutter classification: press materials: steel, composite, inorganic, etc. According to the installation form: wall, wall-side (or hole, the hole). The opening direction can be divided into: roll and side volume two. Fire shutter fire performance rating, there is no national standard, GB14102 the steel fire shutter General technical conditions "in the ordinary steel fire shutter is divided into: F1, fire resistance time 1.50hF2 level, fire resistance time 2.0h compound steel fire shutter is divided into: F3, F4-2.50h refractory time, fire resistance time 3.00h but GB GB14102 on steel fire shutter fire resistance performance ratings are not requirements for fire resistance test for measuring back fire surface temperature, do not take back fire surface temperature rise time as the judgment of fire, in recent years the market VAP-steel fire shutter, evaporative VAP-steel fire shutter, and so on, press the" explanation ", when used as a fire retardant partition separates artifacts, you must take back fire surface temperature rise as fire resistance of the judging criteria. To distinguish between these two different conditions of fire resistance of fire shutter of classification, in fire shutter grading standards introduced previously, the doctrine of "management of experts recommended: according to the national standard of the door and curtain of fire test methods for fire resistance test, GB7633 reach including back fire surface temperature rise in various conditions, the fire resistance ¡ý 3.0h, called Super fire shutter, all in fire resistance test of not taking back fire surface temperature rise as judging criteria collectively referred to as ordinary fire shutter. Technical requirements: 1, curtain panels, Rails, doorway, scrolls, and other parts of the surface does not allow for any cracks, holes and more obvious concavo-convex, hammer marks, Burr, holes 2, welding defects should be firm, smooth appearance, do not allow welding slag, leakage, penetration welding. 3, parts exposed surfaces must be anti-corrosion treatment, coating, coating should be uniform. 4, shutter opens, run average noise should meet the requirements. W ≤ 0.4KW ≤ 50dB0.4 ≤ w ≤ 1.5 ≤ 60dBW ≥ 1.5KW ≤ 70dB5, curtain panels embedded rail depth. Entrance width B1mm B "3000 each end embedded depth ≥ 45mm3000 ≤ B" 5000 ≥ 50mm5000 ≤ B "9000 ≥ 60mm6, guide to the top of the arc should be formed, and its length should be more than the entrance at least 75mm guides with smoke properties must have smoke unit, used materials should be non-combustible material insulation smoke unit and shutter surface should be even close fitting, fitting surface should not be less than 80%. 7. rails of sliding surface should be smooth and straight, straightness per meter cannot be larger than length of linear 1.5mm shall not exceed 0.12%. 8, fire shutter seat plate and ground clearance of not more than 20mm. 9, fire shutter should be set manually hoisting device for power. 10, should have to rely on shutter weight decrease performance, with constant speed performance, place the appliance manually speed operating force not greater than 50N. 11, used for the evacuation of the aisle, export of fireproof roller shutter should be set at the other side of the button, set the linkage should be used in smoke, temperature detector, dropped to 1.5m Department should delay function. 12, fire shutter linkage decline, the controller should be able to issue a beep signal. 13. adopt fire shutter instead of firewall, its fire shutter should be consistent with the fire resistance of the firewall, or in its sides set closed sprinkler system, its nozzle spacing should not be less than 2.00m. 14, fire shutter should use fire power supply, power cable should wear a concealed metal tube, the downlead should take fire protection measures. 3. fire shutter installation and debugging FAQ: 1, curtain plate coating, rust. 2, curtain plate unsoldering, leakage welding phenomena, the welding point with slag. 3. curtain panels have a noticeable pressure hole, a bump, penetrating pores. 4. curtain panels, guideway does not meet the requirements, straightness per meter cannot be larger than length of straightness 1.5mm, shall not be greater than 0.12%. 5, curtain panels embedded rail depth does not meet the requirements. 6, rail deformation curtain plate stuck or landing is not smooth, the noise is larger. 7, shutter, lower-bit failure or limit line wrong answer. 8, curtain panels not only or not only, phase error, upside down. 9, does not act, and the button contact burned, line is blocked. 10, seat plate with a ground clearance greater than 20mm. 11, curtain panels and door pasting does not close, there is a large gap. 12, shutter above or do not completely block or block material does not meet the requirements for fire resistance. 13, curtain plate withhold ceiling or seat plate was side-wall decorations stuck. 14, shutter fire resistance do not meet design requirements or supposes the water curtain protection. 15, owners install stainless steel curtain, etc without a national inspection bodies detection products. 16, shutter take-off and landing speed does not meet the requirements. 17, is not set on the whereabouts of the plant or plant deadweight inconvenience. 18, weight off appliance arm operating force not greater than 50N, does not meet the requirements. 19, weight close institutional failure, shutter cannot stop or do not have constant speed performance. 20, evacuation channel, export of fireproof roller shutter does not set the control button on both sides. 21, evacuation channel, export of fireproof roller shutter without delay function in the place. 22, evacuation channel, export of fireproof roller shutter only smoke detector linked to land. 23, fire shutter only from one side of the detector response or by cross fire shutter set of probes simultaneously. 24, fire shutter linkage landing controller silent alarm function. 25, fire shutter fire power is not used. 26, fire shutter power control cable to wear hose does not meet the requirements, the exposed wires or only set huangla tube, downlead metal pipe failure to take fire protection measures. To sum up fire shutter in the installation process in so many questions, installation and commissioning of units, in accordance with the technicalStandard debugging normal and really make it up to fireproofing function.
