The first step is to install the guide rail
Determine the installation position of the guide rail on both sides of the fire shutter door, use a hammer line to release the guide rail reference line, and release the guide rail connector fixing bolt cross line. The guide rail should not exceed the ceiling.
Use an impact drill to drill the holes for the connecting pieces to fix the expansion bolts on the wall columns. The spacing between the connecting pieces should not be greater than the distance between the two ends of the rail opening. First fix a few connecting pieces up and down, attach the guide rail, correct its verticality and spot weld. After the guide is fixed, check the verticality of the guide rail. Each meter should not be greater than the verticality of the entire length. The composite curtain surface is embedded in the guide rail to a depth of ( See). Fireproof rolling shutter door wholesale
Install the remaining connecting parts, and use spot welding between the connecting parts and the guide rails. The spot welding points between each connecting piece and one guide rail shall not be less than 1.0 pixels, the width of the spot welding shall not be less than 0.05 pixels, and the welding points must be Shouldn't wear phenomenon occur. When using stainless steel guide rails, the welding rods are stainless steel welding rods.
The second step is to install the reel
According to the design center height of the reel in the large sample drawing, determine the center position of the active support plate on the column or wall, and release the center cross line of the expansion bolt.
Using the center of the main support plate as the benchmark, use a horizontal plastic tube to find the corresponding center of the driven support plate and the cross line of the driven expansion bolt hole.
Drilling expansion holes with a percussion drill requires the drill bit to be perpendicular to the cylinder surface. If individual screw holes touch the steel bars and cannot be drilled, they can be moved appropriately, but the firmness and appearance cannot be affected.
Install the straight support wrench
Install the active support plate (the driver bracket is connected in advance and welded to the support plate. Use nuts, spring rings, and flat washers to tighten the expansion bolt that passes through the support wrench hole to require support. The plate surface is perpendicular to the scroll.
The direction of installing the driven bearing plate is the same as above, but before tightening the bolts, the Sichuan horizontal pipe is required to check whether the center height of the driven bearing plate is consistent with the active bearing plate, and the horizontality is controlled at the height of the hole. / Within, if there is any deviation, adjust it in time.
The support plate will follow the weight of the entire door. Although some support plates are fixed with expansion bolts, they are not stable enough, so they should be supplemented with supports or reinforcement ribs and fixed and welded on site. Use cross-bolts to fix the support plate on the brick wall.

Before installing the reel, first orient the hanging plate and install it on the reel, and then install the curtain plate on Hang the board and roll it tightly on the reel and tie it with iron wire.
When hoisting the reel, you must pay attention to safety. If there is a dedicated person to direct the herringbone ladder, scaffolding and hand chain hoist, all must be inspected. When installing, first put the bearings and seats on Plug the optical shaft into the end hole of the reel, and tighten the bearing fixing bolt after aligning the position.
After the reel is installed, you can move the reel left and right to adjust the position. At the same time, use a level ruler and a horizontal tube to check the level of the reel. Adjust After installation, the optical shaft and the reel are fully welded and fixed, and the optical axis and the bearing are fixed with support screws.
When hoisting the reel, special attention should be paid not to damage the curtain plate rolled on the axis, and wooden boards should be used when binding with wire ropes.
The third step is to install the auxiliary axle. For special occasions, when the auxiliary axle must be installed
Determine the height of the center of the auxiliary axle at one end of the door pillar, release the cross line of the bearing plate connecting bolt hole, use this as a benchmark, and just level the pipe. Find the center position of the secondary shaft of the door pillar at the other end and release the crosshair of the screw hole of the bearing plate.
Use an impact drill to drill the expansion bolt holes. The requirements for installing the expansion bolts are the same as before.
Install the bearing seat and secondary shaft, and review them at the same time. Level, the operation is the same as the reel.
The fourth step is to install the fire shutter door motor
First put the chain on the sprocket on the bracket. Before fixing the drive base, put the chain on the small sprocket and tighten it. Fix the bolts. At this time, shaking the chain can make the scroll rotate.
Step 5: Curtain Plate Installation
First loosen several curtain panels on the roller blind, and use a horizontal tube and a ruler to check the unevenness of the roller blind. If the tilt is not greater than the height of the opening, find out the reason and make adjustments.
Use the scroll to rotate the curtain plate, and finally install the bottom beam of the curtain plate. Pay attention to the head seal when putting on the curtain plate , In addition, if you thread the remaining curtain panels together in advance, pay special attention to the movement and do not let the curtain panels deform when bundling.
Check whether the arc bend on the guide rail is suitable, and then lower the roller blind. Walk around to see if there is any jamming phenomenon.
Step 6: Install the supporting wheel bracket. When it is necessary to install the supporting wheel, first determine the position of the bracket on the wall pillars on both sides of the door. The method is the same as the scroll. Install the bracket before installing it. The center height and level of each supporting wheel should be unified and then fixed.
Step 7: Install the electric control box, lock box, etc.
Place the lock box as required, and the screw hole cross of the electric control box Line, use an impact drill to drill holes. The lock box and electric control box should be installed flat and vertically, and should be fixed with or bolts, and the fixation should be firm.
Install the wire tube to connect the lock box and the electric control box. The wires at both ends of the wire tube should be tightened with special nuts. If necessary, copper joints can be used to connect the wire tube. The spacing between the wire tubes is normal
Does not exceed.
Install electrical control panel and limiter.
Connect electrical connecting wires, independent wires, power cords, signal wires, etc. The wiring standards are operated according to the regulations for low-voltage user electrical installations. The wires at both ends of the metal hose are wrapped with plastic tubes or (yellow wax tubes), and the grounding wire is double-colored. Please pay special attention to the grounding wire to be firm.

Plug in the power, manually lower the roller shutter one third of the way, push the button to roll the curtain panel, adjust the upper and lower limits, and then operate the roller shutter up and down several times to check whether the roller shutter is running smoothly.
Step 8 Install the fire partition wall
Place the fire partition moisture line. The fire partition wall should be as close to the reel and guide rail as possible without affecting the roller shutter.
According to the laying out line, use an impact drill to drill expansion bolts on the side of the wall and fix it on the top.
Install the fireproof board into the angle steel frame and fix it with electric welding. The installation of the fireproof partition wall must be straight and firm.
Step 9: After the paint is installed, apply anti-rust paint to the parts that have not been treated with anti-corrosion and the welding scars (the welding slag and rust layer should be removed during welding).
