2. Use an impact drill to punch holes for fixing expansion bolts of connectors on the wall column, between the connectors.
The distance shall not be greater than 600.
Mm, and the distance between both ends is 100.
Hmm.
Fix several joints up and down first, paste the guide rail, correct its verticality and spot weld, and then check the verticality of the guide rail after the guide rail is fixed, which shall not be greater than 5 per meter.
Mm, the verticality of the total length shall not exceed 20.
Mm, the depth of the composite curtain embedded in the guide rail (see GBl4 102—2005).
3. Install the remaining connectors, and spot welding is adopted between the connectors and the guide rail. The spot welding between each connector and the guide rail shall be no less than 5 points, and the spot welding width shall be no less than 5.
Well, the welding place.
Never wear it.
When stainless steel guide rails are used, covered electrode adopts stainless steel covered electrode.
Step 2: Install the reel 1. According to the design center height of the drum in the detail drawing, determine the center position of the active support plate on the column or wall, and release the center crosshair of the expansion bolt.
2. Based on the center of the main bearing plate, find out the corresponding driven bearing plate with horizontal plastic pipe.
Center and driven expansion bolt hole crosshairs.
3. Punching: Drill the expansion hole with an impact drill, and the drill bit is required to be perpendicular to the cylinder. Individual screw holes can move properly if they touch the steel bar, but they can't affect the firmness and appearance.
Step 3: Install the countershaft
In special occasions, it is necessary to install the shaft at 1, determine the height position of the center of the auxiliary shaft at one end of the door post, and release the crosshairs of the bearing plate connecting bolt holes. On this basis, the center position of the auxiliary shaft of the door post at the other end can be found by leveling the pipe.
Pay out the crosshairs of the screw holes of the support plate.
2. Drill the expansion bolt hole with an impact drill, and the requirements for installing the expansion bolt are the same as before.
3. Install the bearing seat and the auxiliary shaft, check the levelness at the same time, and make the same reel.
Step 4: Install the fire shutter motor, put the chain on the sprocket on the bracket, put the chain on the small sprocket before fixing the driving base, and then tighten the fixing bolts. At this time, shaking the chain can make the reel rotate.
Step five:
The curtain plate is installed as 1. First, loosen a few curtain plates on the roller blind, and check that the unevenness of the roller blind is not greater than 1/300 of the height of the hole with a horizontal pipe and a ruler. If the inclination exceeds the tolerance, find out the reason and adjust it.
2. Rotate with the scroll, put on the curtain board, and finally install the curtain board bottom beam.
Pay attention to your head when you wear the curtain board. In addition, it is also important to put other curtains together in advance.
Do not pay attention to the deformation of the curtain plate when moving the bundle.
3. Check whether the arc bending of the upper mouth of the guide rail is appropriate, then put down the shutter and walk around to observe whether there is any jamming phenomenon.
Step 6: When the roller frame needs to be installed, first determine the positions of the brackets on the wall columns on both sides of the door.
Fatong scroll.
After installing the bracket, install the idler. The center height and levelness of each idler should be consistent, and then fixed.
Step 7: Install the electric control box, lock box, etc. 1. Place the lock box as required, pass through the thread of the electric control box, and drill holes with an impact drill.
Lock box and electric control box should be installed horizontally and vertically, and fixed with M6 or M8 bolts, and the fixation should be firm.
2. Install the conduit connection lock box and electric control box, and use special nuts for stranded wires at both ends of the conduit.
Tightening, if the buyer needs, can be connected by copper connector, and the distance between the wire and the pipe clamp is generally not more than 100cm.
3. Electrical control panel and limiter.
4. Connect the electrical connection wires and turn off the wires, power cables and signal wires. The wiring standard shall conform to the "Regulations for Electrical Equipment of Low Voltage Users". The two wires in the metal hose should be wrapped with plastic pipe or (yellow wax pipe), and the grounding wire should be double-color wire. Pay special attention to the grounding wire.
5. Turn on the power supply, manually lower the shutter by one-third button to roll the shutter plate, adjust the upper and lower limits, and then walk the longitudinal shutter up and down several times to check whether the shutter runs smoothly.
Step 8:
Install the fire partition wall 1 and put away the position line of the fire partition wall. The fireproof partition wall should be as close as possible to the scroll and guide rail without affecting the rolling shutter.
2, according to the pay-off, with an impact drill on the side of the wall, on the top of the expansion bolt.
3. Put the fireproof board into the angle steel frame and fix it by welding. The installation of fire partition should be straight and firm.
Step 9: Paint: After installation, apply anti-rust paint on the welding scar (welding slag and rust layer should be removed) on the parts without anti-corrosion treatment.
