[0029] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION
[0030] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] For example, see Figure 1 The present invention provides a technical solution: a metal tile roof construction method, the method comprising the following steps:
[0032] Preparation stage: Select metal tile materials made of aluminum-zinc alloy, in which the aluminum content is not less than 55% and the zinc content is between 43.4% and 44.4%, to ensure that the metal tile has good corrosion resistance and strength. At the same time, prepare galvanized square tubes as tile hanging strips with a diameter of 25mm and a wall thickness of 2.5mm, as well as matching installation nails, repair glue and weather-resistant sealant;
[0033] Waterproof layer construction: Lay a waterproof layer on the base layer. The waterproof layer includes a cement-based penetrating crystallization coating waterproof layer and a polyurethane coating waterproof layer. Ensure that the waterproof layer is continuous, undamaged, and meets the design requirements;
[0034] According to the roof area A and the unit area consumption of waterproof layer material q, the formula V = A q Calculate the total volume of the required waterproof layer material to ensure that there is enough waterproof layer material and no excess; by accurately calculating the amount of waterproof layer material used, both construction efficiency is guaranteed and material waste is avoided.
[0035] Installation of drainage strips: Lay drainage strips on the waterproof layer along the roof slope to ensure that the drainage strips fit tightly with the waterproof layer and are firmly fixed. The installation angle and position of the drainage strips can be accurately calculated using trigonometric formulas to ensure that rainwater can flow smoothly along the preset path to the drainage system, reduce the risk of water accumulation, and protect the roof structure.
[0036] According to the roof slope θ and the spacing d between the drainage strips, the installation angle and position of the drainage strips are calculated using trigonometric formulas to ensure that the drainage strips can effectively guide rainwater to the drainage system.
[0037] Base treatment: Clean the roof base, remove debris and dust, and use cement mortar to level it, ensuring that the base flatness is within ±3mm and meets the slope requirements of the design;
[0038] Installation of tile hanging strips: According to the standard of installing two tile hanging strips for every meter of roof width, fix the tile hanging strips on the base to ensure that they are level and evenly spaced;
[0039] Laying of metal tiles: Lay the first row of metal tiles from the eaves, ensuring that the metal tiles protrude from the eaves by at least 30mm. When laying upwards, overlap adjacent metal tiles left and right, with an overlap width of at least 60mm, and use mounting nails to fix them at the center line of the overlapped tile arc. Use at least 4 mounting nails to fix each metal tile. For areas with strong winds, increase the number of mounting nails per metal tile to 6 to enhance wind pressure resistance. The laying of metal tiles starts from the eaves, strictly following the requirements for overlap width and number of fixing nails, ensuring close connection and overall stability between metal tiles. In areas with strong winds, increase the number of fixing nails to further enhance wind pressure resistance.
[0040] Fixing and sealing: After the installation nails are fixed, use repair glue to seal the nail cap to prevent water seepage. At the same time, use weather-resistant sealant to seal the joints, ridge tiles and eaves of the metal tiles to ensure waterproof effect;
[0041] Inspection and acceptance: After the construction is completed, a comprehensive inspection is carried out to ensure that the metal tiles are laid flat, without omissions or damage, and necessary adjustments and repairs are made. At the same time, a waterproof test is carried out to ensure that there are no leaks on the roof.
[0042] Specifically, the spacing between tile hanging strips is controlled between 250mm and 300mm, based on the estimation formula of the standard value of wind load:
[0043] ω k =β z μ s μ z ω0;
[0044] Among them, β z is the wind vibration coefficient, μ s is the wind load shape coefficient, μ z is the wind pressure height variation coefficient, and ω0 is the basic wind pressure.
[0045] Specifically, the raw material ratio of the metal tile also includes 0.2% to 0.5% of rare earth element additives to improve the toughness and wind pressure resistance of the material, thereby enhancing the durability of the metal tile under severe weather conditions.
[0046] From the above, it can be seen that this metal tile roof construction method reflects high standards from material selection to construction completion. Aluminum-zinc alloy tiles are selected and rare earth elements are added to improve performance, ensuring the corrosion resistance and strength of the tiles. The waterproof layer adopts double protection and accurately calculates the amount to improve construction efficiency and avoid waste. The installation of water-flowing strips and tile hanging strips is accurately calculated to ensure smooth drainage and a stable structure. The laying of metal tiles strictly follows the specifications, especially in windy areas, fixing nails are added to enhance wind resistance. Finally, through comprehensive inspection and waterproofing tests, the construction quality is ensured. The metal tile roof is both beautiful and durable, and can adapt to various severe weather conditions.
[0047] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that, in the base treatment step, the special cement mortar used contains a waterproof additive to enhance the waterproof performance of the base; it can not only enhance the strength and flatness of the base, but also significantly improve its waterproof performance, laying a solid foundation for the subsequent waterproof layer and metal tile laying.
[0048] Specifically, the tile hanging strips are fixed with special fixings to improve the stability and durability of the installation; the fixings have excellent corrosion resistance and high strength, which can ensure that the tile hanging strips remain stable and not loose under severe weather conditions. Through precise measurement and positioning, the horizontality and spacing of the tile hanging strips are ensured to be consistent, providing reliable support for the laying of metal tiles.
[0049] Specifically, during the laying of metal tiles, a special rail system is used to assist the laying, ensuring the flatness and overlap accuracy of the metal tiles. The rail system can accurately control the laying direction, spacing and flatness of the metal tiles, ensuring that each tile can be accurately and quickly installed in the predetermined position. At the same time, the rail system also facilitates construction personnel to make adjustments and corrections, improving laying efficiency and quality.
[0050] Specifically, the overlap of metal tiles adopts double-layer overlap to enhance the waterproof performance of the roof; wherein, the overlap of metal tiles adopts double-layer overlap technology, that is, another layer of tiles is laid on the edge of the first layer of tiles to form an overlapping cover, thereby greatly increasing the waterproof performance of the overlap and preventing rainwater from seeping in from the overlap gap. At the same time, the double-layer overlap can also enhance the overall strength and stability of the roof.
[0051] Specifically, the metal tile installation nails are made of specially designed anti-weathering materials to improve their durability; the installation nails have excellent corrosion resistance, weathering resistance and aging resistance. Even after long-term exposure to harsh environments, the installation nails can maintain stable mechanical properties and good appearance, ensuring the firm installation and long-term use of the metal tile.
[0052] Specifically, the repair glue and weather-resistant sealant are made of highly elastic and aging-resistant materials to adapt to the temperature changes of the roof; in the repair and sealing process, ensure that all joints and holes are fully filled and sealed to prevent rainwater penetration and air circulation.
[0053] Specifically, during the inspection and acceptance steps, professional testing equipment is used to test the waterproof performance of the roof. The testing equipment includes:
[0054] Infrared thermal imager: Infrared thermal imager measures infrared radiation on the surface of an object and converts it into a visual thermal image. In the metal roof waterproofing inspection, the infrared thermal imager can identify the local temperature rise area caused by leakage, thereby helping the inspectors to quickly locate the potential leakage point;
[0055] Water tightness test equipment: including a pressurizing device and a water sprinkling system, used to simulate actual rainfall and water pressure conditions to test the water tightness of the roof. By gradually increasing the pressure and evenly sprinkling water, observing and recording whether there is leakage on the roof, the waterproof performance is evaluated;
[0056] Moisture meters and leak detectors: Moisture meters are used to measure moisture conditions under metal roofs, while leak detectors can more accurately detect tiny water seepage phenomena. These devices play an auxiliary role in the inspection process and help confirm whether the roof is truly waterproof.
[0057] As can be seen from the above, the base treatment part of this metal tile roof construction method uses special cement mortar containing waterproof additives to enhance the waterproof performance. The tile strips are fixed with special fixings to ensure stability and durability. During laying, the rail system ensures that the metal tiles are flat and overlap accurately. The double-layer overlap design further enhances waterproofing. The use of weather-resistant installation nails and weather-resistant sealants improves overall durability. During the acceptance stage, with the help of professional tools such as infrared thermal imagers, water tightness test equipment, hygrometers and leak detectors, the roof waterproofing performance is comprehensively evaluated to ensure construction quality. These specific measures not only improve construction efficiency, but also ensure the long-term waterproof effect and service life of metal tile roofs.
[0058] Example 3, based on Example 2, introduces 3D scanning technology and intelligent spraying robots in the preparation stage to improve construction efficiency and accuracy. At the same time, drone inspection technology is used in the inspection and acceptance steps to ensure that no defects and problems are missed.
[0059] The specific implementation process is as follows:
