How to write the construction scheme of cement tile roof?

A, slope roof truss structure construction:

1, cleaning the existing roof;

2. Pay-off according to the actual situation;

3, according to the requirements of roof slope masonry gables on both sides;

4, pull line, according to the size of brick column masonry, and leveling, make each column on the same slope, on both sides of the gables on the same plane; ;

5, according to the conditions to install mountain ridge, and straightening.

Second, the roof pay-off

1, the distance along the river is 450~600mm, and elastic ink lines are evenly arranged on the vertical eaves.

2, hanging tile spacing is not more than 345mm, to ensure that the upper and lower rows of tile lap is 75mm, let two eaves tile give full play to the role, in order to prevent rain leakage;

3. The waterline size is 40mmx20mm, and it is fixed with steel nails longer than 50mm according to the position of the chalk line, with the maximum spacing of 500mm. The end is 20mm away from the eaves.

4. The size of the hanging tile is 30mmx30mm, and it is fixed on the adhesive tape with a 3. 1~3.4mm round steel nail with a diameter of 50~60mm according to the position of the chalk line.

5. Drainage ditches and inclined walls should be added along the river.

From the center line of the inclined gutter 160MM (along the width direction of the inclined plane), two smooth noodles are fixed on each side; Other streamlines are horizontally connected with the streamlines in the inclined trench, and the upper hanging tiles shall not exceed the edge of the streamlines in the inclined trench, and the corresponding clear width shall be maintained.

Third, the main tile installation

1, laying rules of main tile on slope:

(1) The main tiles are laid from right to left and from bottom to top.

(2) The upper and lower rows of overlapping can be staggered or laid in pairs.

(3) Fixation of ceramic tile:

(4) The two rows of tiles around the eaves of the roof are all fixed with the quick-tooth screws and tapping buttons of the main tiles.

(5) Every other middle tile is fixed with self-tapping buckle and screw.

(6) The left and right margins of the ceramic tile are 50mm away from the cornice.

2. Laying the main tile at the inclined ridge position.

The main tile of each slope should be aligned with the oblique ridge line, and then cut after arching. The width of flat-fell seam should be as close as possible to the drainage ditch and the main tile cut by inclined ridge, which is convenient and firm to fix. It is recommended to fix it with tile-cutting buckle.

Fourth, the fitting ceramic tile installation

Eaves and slopes are laid from bottom to top. Dry construction, horizontal ridge and inclined ridge can be filled with cement mortar.
