[China Aluminum Network] dark buckle upright seam aluminum alloy roof system has only been widely used in recent years in China, is the first to fix the aluminum alloy seat with screws on the purlin, and then the roof buckle on the seat of the plum head Later, the overlapping edges of the roof panels were snapped together by an electric edger. With this method of fixing, the roof is not exposed to screws, and the entire roof is not only beautiful and clean, but also eliminates the hidden danger of water leakage caused by screw holes. 3004 aluminum magnesium manganese alloy plate has strong corrosion resistance, especially in the acidic environment, its corrosion resistance is better than steel plate and ordinary aluminum alloy plate; In addition, the screws used in the dark buckle upright seam aluminum magnesium manganese roof system, The accessories are all accessory products and the entire system has good anti-corrosion capabilities.
The installation process is as follows: Putting → In Place → Undercut → Edge trimming.
1) The plane control of the lay-out roof panel is generally completed by positioning the fixed support below the roof panel. After the roof panel mounts are installed, only the board-end positioning lines need to be set. Generally, the distance from the edge of the plate to the drainage ditch is the control line. The length of the plate extending beyond the edge of the drainage ditch is slightly larger than the design and is convenient for trimming.
2) Raise the plate to the installation position in position. When positioning, align the plate-end control line first, then press the overlapping edge into the overlapping edge of the previous plate, and check if the overlapping edges are tightly connected.
3) After adjusting the position of the bite plate, use a special electric sewing machine to perform the sewing. The undercut is required to be continuous and flat, and no distortion or cracking can occur. In the occlusal crawling process of the undercutting machine, the lap joint must be tightly clamped within 1 mm in front of it, which is also the key to the quality of the mechanical undercut. The roof panels that are in place on the day must be undercut to prevent the panels from being blown or scraped by the wind.
4) After the panel trimming is completed, the edge of the edge of the panel needs to be trimmed to ensure that the edge of the panel is neat and beautiful. The length of the roof panel extending into the gutter should be ≥80mm.
5) After the trimming process is finished, at the end of the roofing part of the roof, using a special jig, turn the board upside down, and control the angle at about 45° to ensure that the rainwater from the fistula is discharged to the inside without blocking. One side of the head and the flashing board infiltrate into the room.
6) Installation points
1 Start the installation of the roof panel after completing the pre-installation test.
2 using mechanical bite seaming installation. After the roof panels are laid, they should be bitten by an undercut machine as soon as possible to improve the board's integrity and bearing capacity.
3 When the panel is laid, after the axis is completed, first manually align the panel with the support, and then put the undercutting machine on the joints of the 3 panels to support the double underfoot of the undercutting machine to prevent overturning. .
4 When the roof panel is installed, two workers first move along the ribs at the front of the board and the plate, and the lock stitches of the board and the support under the board are firmly fixed while walking. The latter person pulled the guide rope of the mouthpiece to make it closely follow the person and close the roof panel tightly.
7) After the completion of the installation, after the completion of the reinstallation of the aluminum-magnesium-manganese-based roof panels, the properties of the installed metal roof panels are tested to ensure that the metal roof panels are waterproof and wind-resistant.
