2. Installation steps of colored steel tile roof of farm house: firstly, two 4m*3m scaffolding are built with steel pipes, and each foot of the scaffolding is equipped with a wheel, which is convenient to use and can be pushed.
3. Install the inner panel on the roof where the color steel tile is to be installed. Each wave crest is fixed with a special 30mm self-tapping screw, and the color of the nut is the same as that of the color plate.
4. After the inner panel is installed, thermal insulation cotton can be laid on it. Note that the joint of thermal insulation cotton needs to be sealed with special tape.
5. Fix the fasteners on the purlins with self-tapping screws, and remember that there must be fasteners on each purlin.
6. After installing the fixing parts, put a steel plate on the fixing parts, and then press it against the bottom groove of the center rib and inner rib of each fixing part until it is fully engaged, and lock the middle of the colored steel tile with a special locking edge.
7. Install the rear fasteners one by one, one on each supporting surface, to ensure that the interlocking ribs of the fasteners are engaged with the outer ribs of the installed steel plates.
8, pull a line along the bottom of the color steel plate, check whether both ends of the color steel plate are in the same straight line. After inspection, the second color steel tile can be placed on the second row of fixed parts, with the inner rib on the outer rib of the first steel plate and the middle rib on the middle rib of the fixed part. Repeat the operation method of the first board and install the remaining color steel tiles in the above order.
9. Both inside and outside the wallboard need to be screwed. As for how to twist, please refer to the second step.
10, the next step is to install the gutter, connect the gutter to the ground for 9m, and then pull it to the roof with hemp rope for installation. Note that when installing the gutter, the line should be kept straight and the stay wire should be straightened.
1 1. After installing the color steel plate, the next step is the essential waterproof treatment. Using a crowbar, the part between the terminal ribs of the steel roof is folded upwards to ensure that the water blown from the inside under the flashing will not flow into the building. Then, the flat plate part between the ribs at the lower end of the steel plate is slightly bent downward (lip-shaped) by using a folding tool to ensure that rainwater is discharged along the terminal end of the steel plate and will not flow back to the lower side of the flat plate chassis under the action of wind.
