What are the specifications of corrugated tile roof? What is the construction technology of corrugated tile roof?

Nowadays, there are many materials and shapes of roofs, some pay attention to practicality, and some pursue beauty. Corrugated tile roof is a kind of roofing material with strong aesthetics, and the design of corrugated tile roof needs to conform to relevant specifications in order to achieve waterproof effect. So, what are the specifications of corrugated tile roof? What is the construction technology of corrugated tile roof? Now Bian Xiao will introduce the effect knowledge of corrugated tile roof to you, hoping to help you understand corrugated tile roof.

What are the specifications of corrugated tile roof?

According to the latest edition of General Principles for Civil Building Design (GB? 50352-2005):

Tile roof slope is:

20%-50% of flat tile;

Corrugated tile10%-50%;

Linoleum tile >; =20%.

The relevant dimensions of flat tile roof shall meet the following requirements:

1? The overlapping width of ridge tiles on two slope tiles should not be less than 40mm on each side.

2? The length of the tiles extending into the gutter and eaves gutter is 50-70mm.

3? The waterproof layer of the gutter and eaves gutter extends into the tile, and the width is not less than150 mm. ..

4? The length of cornice plate picked out by tile head is 50-70 mm.

5? The side tile of the wall or chimney protruding from the roof should be extended into the flood with a width of not less than 50 mm. ..

What is the construction technology of corrugated tile roof?

1. When laying corrugated tile roofs, two adjacent tiles should overlap in the wind direction with the highest frequency in a year. Its lap width: large wave tile and medium wave tile should not be less than half wave; Wavelet tiles should not be less than one wave. The lap length of the upper and lower rows of corrugated tiles should be determined according to the length of roof slope, but it should not be less than100 mm.

2. When laying corrugated tiles by staggered joints on the long sides of the upper and lower rows of tiles, it is advisable to stagger half a corrugated tile, but the corrugated tile and the middle corrugated tile should be staggered by at least one wave, and the corrugated tile should be staggered by at least two waves.

When the long sides of the upper and lower rows of tiles are laid, the angle of the tiles should be cut off in the direction of the tiles at the overlap of four adjacent tiles, and the diagonal gap is not more than 5 mm, so it is not necessary to cut corners on the glass fiber reinforced plastic tiles.

3. Corrugated tiles shall be fixed on metal purlins or concrete purlins with galvanized hook bolts with waterproof washers, or on wooden purlins with galvanized screws; Bolts or screws should be arranged at the top of the cover tile near the overlapping part of the corrugated tile.

On the purlin at the overlapping place of the upper and lower rows of corrugated tiles, each tile should have two bolts or screws; On the purlin of each row of corrugated tiles, a bolt or screw should be set on each cover tile where two adjacent corrugated tiles overlap.

When fixing corrugated tiles with screws in windy areas, the number of screws should be increased appropriately.

4. The nail hole on the corrugated tile should be drilled into a hole, and its aperture should be 2 ~ 3mm； larger than the diameter of the bolt (screw); Don't tighten the bolts or screws that fix the corrugated tile too tightly, and the washer can rotate slightly.

5. When laying glass, glass and steel corrugated tiles, they should be fixed with water screws or countersunk screws, and rubber pads should be added. Each tile should be fixed with purlin at least 6 times.

Glass fiber reinforced plastic corrugated tile shall not be exposed to open fire during installation, and shall be prevented from being injured by heavy objects and tools. It is forbidden to go on the roof before the wave tile and purlin are fixed with bolts.

6. Roof tile or galvanized steel plate should be used for roof and inclined ridge; The gap between ridge tile and wave tile should be sealed with hemp knife ash.

7, the ditch, eaves gutter, corrugated tile into the ditch should not be less than 50mm in length, the gap between the waterproof layer at the bottom of the ditch and corrugated tile should be filled with hemp fiber ash.

8. When the joint between the roof and the wall or chimney protruding from the roof is made of galvanized steel sheet for flashing, the lap width of corrugated tile and flashing should not be less than150 mm. The gap between corrugated tile and flashing should be filled with hemp fiber ash.

Above, Bian Xiao introduced the construction technology of corrugated tile roof for you in detail. This paper introduces eight construction steps of corrugated tile roof in detail, and some problems needing attention in the construction process, which need the attention of builders. And when we buy it again, we must see if it is a product that has passed the relevant inspection, so that the project used for construction is safe. I hope Bian Xiao's introduction can help you understand corrugated tile roof.
