The following applied to the reinforced concrete roofing, for example, introduces the construction process of color stone tiles.
When the color stone metal tile is applied to the reinforced concrete roof, the roof structure of the color stone roof tile is 1) the reinforced concrete structure layer, 2) the leveling layer of the cement mortar, 3) the thermal insulation layer of the extruded board, 4) the leveling layer of the cement mortar, 5) waterproof layer; 6) 4 cm thick cement mortar leveling layer; 7) wooden cistern; 8) wooden battens;
Material requirements
Grassroots requirements: 4 cm thick cement mortar leveling layer to ensure that the surface is smooth, uniform thickness, appropriate strength, concrete leveling layer flatness should be within ± 5 mm, cistern, hanging tile size deviation should be within ± 2 mm.
Color stone metal tile requirements: sub-main tile, ridge tile, flashing board, gutter board, gables, eaves, etc., according to the actual needs of the project to the manufacturers order;
Wooden cistern, hanging tile requirements: the size should be respectively ≥ 5 cm × 5 cm and ≥ 4 cm × 4 cm, and do anti-corrosion treatment;
Cement nails: nailing into the depth of the leveling layer to reach more than 3 cm, in order to ensure the cistern is firmly fixed on the roof structure;
Fixed battens with a nail: nail into the depth of cistern should reach more than 3 cm, in order to ensure that the battens and cistern firmly connected;
Color stone fixed with metal nails: 4 mm × 40 mm wood thread self-tapping screws, galvanized steel nails and so on.
