When installing the main tile of the two slope roof, the center of the peak on one side coincides with the line of CC1(CC2) or DD1(DD2), and the upper and lower parts of the main tile should be parallel with the line of CD and AB, and start installation from one side (CC1 or DD1 line).
It is important to install the tile. Make sure that the bottom edge of the tile and the line of CC1(CC2) or DD1(DD2) are not inclined vertically. After the position is adjusted, fix the tile at the center position (crest) of the purlin and tile at the lower end.
In order to prevent the skew and unevenness caused by one-way lap, the horizontal installation of the main tile should be arranged one by one, that is, the second tile is buckled and the third tile is pressed, the fourth tile buckles the third tile and the fifth tile and clings one tile, and so on.
During the installation process, check the vertical between the bottom edge of the tile and the construction line at any time, and then complete the installation of the fasteners after confirmation.
A section length of the tile to be spliced for longitudinal installation.
The installation of the main tiles of the two sloping roofs should be carried out synchronously on both sides to ensure that the peaks of the positive ridge tiles are consistent.
The main tile is installed with self-tapping nails with a diameter of 6.3mm and a length of 75mm; The vertical ridge tile and oblique ridge tile are installed with self-tapping nails with a diameter of 6.3mm and a length of 110-150mm according to different fixed positions.
When fixing the tile, first place the waterproof ring in the groove under the protective pad, and put the self-tapping nail through the center hole of the protective pad (with the arc face facing down). The electric drill should be perpendicular to the tile surface, and the tightness of the fastening tile nail should be moderate, install the waterproof cap after completion.
Steel purline adopts self-tapping nails or stainless steel angle nails, and wooden purlin adopts self-tapping screws. Drill holes larger than 2mm straight diameter of self-tapping screws on peaks to be fixed, and fix a set of accessories every other crest.
Hip roofed buildings install the main tile first (the method is the same as that of the two slope houses). After the installation of the main tile, install the triangular roofs on both sides. The two sides of the center line CC3 and DD3 are equally installed, and then cut along the oblique line to facilitate the installation of the oblique ridge tile.
