Due to the improper installation of fire shutters, the product is damaged, the operation is not smooth, and other after-sales problems. Occurred on the project from time to time, generally Party A will require debugging and reinstallation. More serious may force the removal and replacement of other brands. Therefore, the installation of fire shutters is not standardized, and a project loses 100,000 yuan, which is by no means an open mouth. To prevent this from happening, summarize the following latest fire shutter installation specifications.
I. Construction procedures for fire shutter installation
Opening measurement → Support plate installation → Rolling door machine installation → Reel installation → Curtain installation one rail installation → Electricity commissioning → Electrical installation → Power connection → Comprehensive commissioning → Cleaning → Acceptance.
Second, the support plate installation
① Determine the installation form (in the column and column side) according to the schematic diagram of the installation structure of the roller blind, and determine the installation height of the roller blind according to the requirements.
② Use a horizontal pipe to find the horizontal position between the two columns, and mark the installation position on the column (beam).
③ Fix the support plate on the column (beam) with M12 × 100 expansion bolts, and use the support angle steel to support it firmly
④ Adjust the level of the two support plates to meet the maximum error ≤10mm, and it should be installed according to the product manual and solid.
Third, the rolling door machine installation
① Check whether the fittings of the rolling door machine are intact, whether the connection terminals are loose, without damage, and check whether the insulation performance is good;
② Fix the rolling door machine on the support plate, and the sprocket centers of each rotating shaft should be coaxial.
③ Install the chain and adjust the center distance. Adjust the bolts to make the chain tension properly, and then tighten the spring pad bolts to avoid damaging the feet of the gear box during operation and ensure the progress of repeated positioning of the roller shutter.
④ Pay special attention to the installation of the elastic piece connected to the chain. Make sure that the installation is firmly locked to prevent it from loosening during operation.
⑤ Fill the chain with lubricating oil to keep the chain well lubricated and prolong its service life.
⑥ The manual device and braking device of the rolling door machine should be flexible and reliable, and there must be no block or difference.
Direction, eliminate slipping phenomenon, and ensure that there is no sudden drop when the roller shutter is running.
Fourth, the scroll installation
① Adjust the length of the reel according to the distance between the two support plates, and connect the reel to the bearing shaft.
Welding is firm. Welding defects such as missing welding, slag inclusion and bubbles are not allowed during welding.
② Polish the welded area with an angle grinder and perform anti-rust treatment.
③ Use a manual hoist to hoist and install the reel between the two support plates, adjust the appropriate clearance, level the bearing and reel horizontality, allow the error to be within 1/300 of the opening, and keep it perpendicular to the support plate to ensure that the reel, bearing shaft, The concentricity of the bearing makes it run freely.
④ Tighten the bearing gland and ensure that there is no looseness.
V. Installation of double curtain inorganic fiber fireproof roller shutter
① Use thick white brown rope to wind on the reel, start the rolling door machine to install the curtain on the reel.
② Tighten the hook plate bolts.
③ The test panel is required to run flexibly up and down, and the panel is not allowed to twist.
④ The anti-channeling mechanism at both ends of the curtain should be firm and firm, and the axial movement of the curtain should be controlled ≤ 2mm.
⑤ There should be a certain gap between the curtain plate and the chain to ensure that it is between 20-30mm to prevent the chain from falling during operation.
⑥ After the curtain is assembled into a roller blind, it should be raised and lowered in parallel during operation. The unevenness of the inclined roller blind is not greater than 1/300 of the opening.
Installation of the stern plate. After the seat plate is installed, the contact with the ground should be uniform and parallel, and the non-parallelness of the two seat plates should not be greater than 50mm.
Six, rail installation
① When installing the guide rail, the upper part should be made into an inverted "eight" shape to ensure that the curtain board does not block when entering the guide rail. The bottom of the guide rail should be buried under the ground to avoid the gap between the floor and the guide rail.
② The verticality error of the roller shutter after installation shall not be greater than 5mm / m, and the total length shall not be greater than 20mm.
③ The dual guide rails should be installed on the same axis, and fixed to the column (wall) body with M12 * 100 expansion bolts, and the fixing parts should be buried in the structure of the column (wall), with a spacing not greater than 600mm-1000mm.
④ The roller shutter should run smoothly and smoothly in the guide rail, and no collision or impact is allowed.
Seven, electrical installation
① Check whether the equipment and accessories of the electrical control box are intact, and whether the terminals are loose.
② Fix the control box with M8 × 60 expansion bolts on a column (wall) that is easy to maintain, and it should be firm and reliable.
③ Install the button box, and install the button box on the sides of the roller shutter for easy operation. The height from the ground is 1.3-1.5 meters.
④ Piping, using JGD φ20 × 1.5mm piping, the required bend radius and connection method should comply with national electrical codes.
⑤ The lines from the electric control box to the door rolling machine, the travel switch and the water control box are protected by φ15 plastic-coated steel pipe, and the length of the hose is not more than 1 meter.
8. Debugging and Testing of Roller Blinds
c Before the electrical commissioning, a comprehensive inspection of the mechanical part is required. Specific inspection items
A. Whether the self-weight drop of the roller shutter is normal and flexible
B. Whether the manual opening and closing device is free
C. Whether the door roller brake is normal
D. Whether the bearing cap is tightened without loosening
E. Whether the drive sprocket is on the same plane and the chain tension is appropriate
F. Whether the support plate reinforcement is loose
G. Whether the curtain runs normally in the guide rail, without blocking
H. Whether the amount of movement between the curtains meets the requirements
② Before stand-alone commissioning, check whether the electrical wiring is correct, and whether there are loosening or falling off, and then turn on the power after correct.
③ Start the button by jogging and run without abnormality and sensitive braking.
④ Debug the upper, middle, and lower strokes of the roller blind, and position it at the specified position, and it is required that the repeated positioning error of each position is not greater than 10mm.
The final acceptance and commissioning are top priorities. When submitting to Party A for acceptance, self-inspection is indispensable. It is much better to find the problem and solve it yourself than to be solved by others.
