Step 1: Install the guide rail. 1. Determine the installation position of the guide rails on both sides of the fire shutter door, use hammer wire to release the guide rail baseline and release the crosshairs of the fixing bolts of the guide rail connector. The guide rail shall not exceed the ceiling by less than 75 cm. 2. Use an impact drill to fix the expansion bolt hole on the wall column with connectors. The distance shall not be greater than 600? Mm, and the distance between the two ends is 100? Well, first fix several joints up and down, 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 perpendicularity 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, where is the weld? 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 detailed drawing, determine the center position of the column or movable support plate on the 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. 1. Install the straight support wrench. (1) Install the active support plate (the driver bracket is pre-connected and welded on the support plate), and tighten the expansion bolt through the hole of the support wrench with nuts, spring retaining rings and flat washers. The surface of the support plate is required to be perpendicular to the reel. (2) Install the driven bearing plate in the above direction, but before tightening the bolts, please check whether the center height of the driven bearing plate is consistent with the active bearing plate, and the levelness should be controlled within 1/300 of the hole height. If there is any deviation, adjust it in time. (3) With the weight of the whole door, some support plates are fixed with expansion bolts, but they are not stable enough. They should be fixed on the spot with support or reinforcing ribs and welded on the brick wall with through bolts.
5. Install the fire reel. ( 1)? Before installing the reel, orient the hanging plate and put it on the reel, then put 4-6 curtain plates on the hanging plate, tightly wrap them on the reel and tie them firmly with iron wire. (2)? When hoisting the scroll, be sure to pay attention to safety, have a special person to direct it, and check the ladder, scaffolding and chain block. When installing, first insert the optical axis of the sleeve bearing and the seat into the end hole of the reel, align the position, and then tighten the bearing. (3)? After the scroll is wound, you can move the scroll left and right to adjust the position. At the same time, check the level of the reel with a spirit level and a horizontal tube. After adjustment, the optical axis and the reel are completely welded and fixed, and the optical axis and the bearing are fixed with the support head screw. (4)? When hoisting the reel, pay special attention not to damage the curtain plate wound on the shaft, and use steel wire? After the rope is tied, the boards should be padded.
Step 3: Install the countershaft? On special occasions, when the shaft must be assembled: 1. Determine the center height position of the auxiliary shaft at one end of the doorpost, and set out the crosshair of the connecting bolt hole of the backing plate. On this basis, level the pipe and find out the center position of the auxiliary shaft at the other end of the door post. 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, and check the levelness at the same time. The operation is the same as that of the reel.
Step 4: Install the fire shutter door motor. First, put the chain on the sprocket on the bracket, then 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 5:? 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. 3. Pay attention to your head when placing curtain boards, and it is especially important to put other curtain boards together in advance. Do not pay attention to the deformation of the curtain plate when moving the bundle. 4. 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 in the design, 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 wiring duct to connect the lock box and the electric control box, and use special nuts for stranded wires at both ends of the wiring duct? 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 press the shutter one-third key to roll the shutter plate, adjust the upper and lower limits, and then manipulate the shutter to walk 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.
After the above nine steps are completed, a complete fire shutter door is successfully installed.
The above suggestions I gave you are the installation process of our fire shutter doors, and what problems should be paid attention to in the usual installation are elaborated for you. So we must pay attention to these details when installing to prevent some unexpected events. At the same time, I would like to remind you that even if a fire shutter is installed, you should not take it lightly. We should pay attention to the safety of using fire at ordinary times, so that our life can be more comfortable.
