Roof Connection Points Solved
1. To ensure effective drainage of eaves and roof overhangs, maintain and service the lower eave boards together. The best choice for the overhang is a metal waterproofing board or corrosion-resistant coating eave board. Extend the metal waterproofing board 100mm inward from the roof edge towards the overhang, and then slope it downwards to cover the overhang. Before the equipment shingles, securely fasten the metal waterproofing board as shown in the diagram to the overhang and steel purlins.
2. Flashing at the junction of the roof and wall is custom-fabricated on-site using metal sheets or corrosion-resistant coating panels to the specified dimensions. One end is fixed in place on the wall, while the other is secured to the roof tiles.
3. Water Tank and Chimney Flashing: The water tank and chimney should intersect with the roof tiles at four points. They can be divided into flat face flashing and curved flashing. Flat face flashing refers to the roof tiles starting on the upward slope of the building, where metal sheets can be custom-fabricated into flashing panels based on site limitations, fixed below the building's contour and above the steel joists under the roof tiles. Flat face under flashing refers to the roof tiles being on the downward slope of the building, where metal sheets can be custom-fabricated into flashing panels based on site limitations, fixed below the roof tiles and above the building's contour. Curved flashing refers to the roof tiles being at the intersection of the two sloping sides of the building, where metal sheets can be custom-fabricated into flashing panels based on site limitations, fixed below the building's contour and above the tile surface.
4. The panoramic sunroof coping solution involves first securing the sides and upper slope panels of the panoramic sunroof in place on the roof, before the roof tiles are installed. Once the瓦 equipment along the downhill path of the panoramic sunroof is completed, a metal drainage panel from a manufacturer is then placed over the tiles.
5. Drainage Pipeline Solution Near Wahu Window: To ensure effective metabolism of precipitation above the Wahu Window, drainage outlets should be set on both sides of the window. The construction of equipment and engineering follows the methods of dealing with the back wall, water tank, and chimney flashing.
Solar energy generation equipment and waterproof attic skylight roofs for solar power generation, in normal circumstances, the construction work is coordinated based on the current state of the roof and the overall planning of the building project. Common methods for solar energy generation equipment include pre-burying service platforms for roof-mounted equipment and creating support frames on sloping roofs. The pre-buried service platform involves embedding sufficient width for solar energy generation equipment on one side of the roof, with the rest covered by sloping roofs. Solar power generation on sloping roofs involves constructing support frames above the slope. Taking a steel structure with steel trusses as an example: the solar panel supports must be welded to the four upright rods of the load-bearing main beam on the roof tiles, followed by welding two parallel load-bearing beams on top of the four rods. The total width of the two load-bearing beams is determined based on the total width of the solar power generation equipment, and the top of the two beams must maintain a consistent level to facilitate the solar power generation equipment. The base of the four upright rods for the roof tiles should be treated appropriately.
Four: Lightning Rod Grounding Devices and Moisture Protection - The construction of lightning rod grounding devices should be in accordance with the overall planning of the building project and communicated to the construction team. Common grounding device equipment methods are shown in the figure below, and moisture protection solutions must be implemented for the lightning protection equipment on the roof tiles.
III. Construction Site Safety and Completion Cleanup
1. During construction on the slope, the team primarily checks the stability and integrity of the roof steel purlins. The synthetic resin tiles should settle along the slope, with no more than 3 tiles per stack. They discourage placing materials on non-fixed steel purlins to prevent them from falling or being broken by strong winds.
2. Non-slip slides must be used during construction on sloping roofs, and the construction team must prioritize safety; construction activities should be discouraged during rain, snowfall, and when wind speeds exceed 6 on the Beaufort scale.
3. After the roof tile equipment is completed, it is necessary to clean up the fine materials on the roof. Check for any damage to the roof tiles and clean the roof. If there are misdrilled holes, they can be sealed with epoxy resin glue.
