What is the construction technology of "tile roof"?

Roof tile dry hanging construction plan 1.1 process flow \x0d\ structural layer → 20 thick 1:3 cement mortar leveling layer → one layer 2 thick SBS (type 2) modified asphalt waterproof membrane air barrier layer → 60 thick extruded polystyrene

x0d\1. Structural layer\x0d\Clean the structural layer and lightly water the surface to moisten it\x0d\2. Cement mortar leveling layer\x0d\20 thick 1:3 cement mortar leveling layer is to closely adhere to the air barrier layer

An integral air barrier film with a certain thickness and elasticity is formed on the leveling layer to act as an air barrier.

During construction, in addition to ensuring the flatness of the leveling layer, the details of the structure must also be dealt with, specifically: \x0d\1) Set grating joints on the leveling layer to prevent cracking of the leveling layer from causing cracking of the waterproof layer. The spacing between grating joints is 6m.

, the seam width is 20mm, and filled with sealing material.

\x0d\2) The corners of the leveling layer should be formed into arcs with a radius of not less than 50mm.

\x0d\3) The junction between the water outlet and the roof should be sealed, and the depth of the waterproof coating extending into the outlet should not be less than 50mm.

\x0d\3. SBS modified asphalt waterproof membrane air barrier layer\x0d\4. Extruded polystyrene board insulation layer\x0d\ 60 thick insulation layer should be laid evenly and tightly connected.

\x0d\5. Cement mortar leveling layer\x0d\20 thick 1:3 cement mortar leveling layer is used to make the waterproof coating closely adhere to the leveling layer to form an overall waterproof membrane with a certain thickness and elasticity to play a waterproof role.

.

During construction, in addition to ensuring the flatness of the leveling layer, the detailed structure must also be dealt with. For details, see the leveling layer separated by the same layer.

\x0d\6. SBS modified asphalt waterproof membrane waterproof layer\x0d\For details, please refer to the above method for roof waterproof layer treatment\x0d\7. The thinnest part is 20 thick and 1:3 cement mortar lying tile layer\x0d\According to the design requirements

, ensure that the thickness of the lying tile layer is ≥20, and it is equipped with steel mesh Φ6@500×500\x0d\8. Spanish tile paving\x0d\Preparation work before construction\x0d\1. The height of the herringbone board on the gable wall should be

As high as the back side of the tile hanging strips.

\x0d\2. Before laying roof tiles, gutters and other channels must be installed along the drainage ditch (inclined ditch).

\x0d\3. Clear all obstacles, such as completing all cement mortar processes, dismantling scaffolding, wooden board molds, etc.

\x0d\4. Fill the reinforced concrete cornice wings and trim them neatly.

\x0d\Installation of tile hanging strips\x0d\1. First install a tile hanging strip on both sides of the top of the water strip, so that the distance between the tops of the tile hanging strips is 4cm.

The size of the hanging tile strips should not be less than 25×25mm. There must be linoleum padding on open and wooden roofs, and it must extend at least 150mm past the top of the ridge.

\x0d\2. Middle part: Starting from the first tile hanging strip downward, install the tile hanging strips at intervals of 332mm-356mm (see the "Tile Hanging Spacing" of Technical Points for details).

Ensure that the amount of tiles used is no less than 9.5 tiles/square meter.

\x0d\3. Install the last tile hanging strip of the cornice: let it be close to the eaves edge, and the height should be the same as the cornice pressure plate, but it must be one inch higher than the other hanging tile strips.

\x0d\4. The connection points of the tile hanging strips should be placed on the center line of the water strips and should be staggered from each other.

\x0d\5. Use card strips to adjust the tile hanging strips to make each row even and flush.

If necessary, you can only adjust the water-slip strips by turning them, and do not cut the tile-hanging strips easily.

\x0d\Installation of roof tiles\x0d\1. Start laying the first tile from the lower right corner of the eaves, and arrange it from right to left until the first row is covered. Note that the tiles at the left and right ends must be kept at the corrugated protrusions.

.

Otherwise, the arrangement of the tiles must be readjusted.

\x0d\2. When laying the second row of tiles, stagger and overlap the tiles with the first row of tiles to make the entire roof stronger and drain rainwater more effectively.

Then use clamping strips to fix the distance from the edge to the ridge every ten tiles to keep the edges of the tiles connected in a straight line.
