Fire shutter doors installation and construction quality control points: 1) Review the hole size and dimensions are consistent with the measurement hole elevation Shanxi fire door manufacturers, namely vertical pop-up guide roll centerline; 2) Fixed reel, gear Luliang fire doors, roll cartridge installation should be flexible rotation; 3) test: first manual test run, and then hoist motor several times to adjust to no stuck, blocking and abnormal noise, open and close several times to meet the requirements, all set up before installing protective hood. When selecting fire shutter doors most important factor is the fire resistance of fire shutter doors. There are two methods of fire shutter fire resistance: one fire shutter in accordance with existing national standards GB7633 "fire test methods door and shutter the" resistance test, including the unexposed surface temperature determination, including the determination condition ; the second is the same fire resistance test carried out in accordance with GB7633 shutter doors fire door prices, according to the standard non-insulated protective layer on the metal shutter waiver provisions unexposed surface temperature and product standards "steel fire shutter general technical conditions" (GB14102-93) requirements and only to a certain distance away from the unexposed surface of the radiant heat intensity and curtain side wear fire to determine whether the fire resistance of rolling shutter. According to fire back surface temperature rise does not include the fire resistance of determining conditions for non-insulated fire shutter, fire resistance of the resulting data, including the unexposed surface temperature than the fire resistance of determining conditions for thermal insulation fire shutter fire resistance to be much longer.
