The previous editor has introduced the reinforcement construction process of roofing tiles in detail. It can be seen that the reinforcement of roofing tiles is very important and construction personnel cannot ignore it. The corrugated roof tile is a roof waterproof component made of thermal insulation asbestos and cement as basic materials, and there is also a glass fiber reinforced plastic corrugated roof tile with chemical materials and reinforced materials. Although the corrugated roof tile has some inevitable shortcomings, it is a rainproof component after all, so we need to understand the construction precautions of the corrugated roof tile! The precautions for the construction of the wave roof tiles are as follows: 1. When laying the wave roof tiles, two adjacent tiles should be overlapped in the direction of the annual maximum frequency wind. The overlap width: large and medium corrugated tiles should not be less than half a wave; small corrugated tiles should not be less than one wave. The overlap length of the upper and lower rows of corrugated tiles should be determined according to the roof wavelength, but should not be less than 100mm. 2. When the corrugated tiles are laid by staggering the lap joints of the upper and lower rows of tiles, half of the corrugated tiles should be staggered, but the large and medium corrugated tiles should be staggered by at least 1 wave, and the small corrugated tiles should be staggered by at least 2 Waves. When laying the upper and lower two rows of tiles so that the long side lap joints are not easy to open, at the lap joints of the adjacent 4 tiles, the corners of the tiles should be cut first, and the diagonal gap should not be greater than 5mm. FRP tiles are not corner. 3. Corrugated tiles should be fixed on metal rafter bars or concrete rafter bars with galvanized hook bolts with waterproof washers, or fixed on wooden rafter bars with galvanized screws; bolts or screws should be set on the crest of the cover tile. On the rafters at the overlap of the upper and lower rows of corrugated tiles, there should be two bolts or screws for each cover; on the rafters next to each row of corrugated tiles, each cover at the overlap of two adjacent corrugated tiles There should be a bolt or screw on the tile. 4. The nail holes on the corrugated tile should be drilled and the hole diameter should be 2-3mm larger than the diameter of the bolt; the bolts or screws for fixing the corrugated tile should not be tightened too tightly, so that the washer can roll slightly. 5. When laying FRP corrugated tiles, use wood screws or butt bolts to fix them, and add rubber pads. Each tile should be fixed to the rafters at least 6 places. Do not touch the open flame when installing the FRP corrugated tile, and avoid heavy objects and objects from smashing the corrugated tile. Before the corrugated tiles and rafters are bolted, the roof is forbidden to get on people. 6. Roof ridges and inclined ridges should be covered with ridge tiles or galvanized thin steel plates; the open space between the ridge tiles and the corrugated tiles should be sealed tightly with ash, etc. 7. When the roof has gutters and gutters, the length of the corrugated tiles extending into the ditch should not be less than 50mm; the open space between the waterproof layer at the bottom of the ditch and the corrugated tiles should be tightly filled with ash, etc. 8. When galvanized sheet steel is used for flooding at the junction of the roof and the protruding wall or chimney, the overlap width between the corrugated tile and the flooding should not be less than 150mm, and the open space in between should be tightly filled with ash.
