Description

Technical Field

[0001] The utility model relates to the technical field of building roof structure construction, in particular to a standing seam locked aluminum-magnesium-manganese plate metal roof structure. Background Art

[0002] With the development of the national economy, the design and construction of large-scale public construction projects, the market has a great demand for high-quality roofing materials and technical systems. The application of advanced metal roofing system technologies and materials such as aluminum-magnesium-manganese plates has changed the current situation where the supply of domestic metal roofing materials is limited to color-coated steel plates. Traditional roofs are mostly color-coated steel structures, reinforced concrete structures, etc. After a period of use, these roofs are prone to water leakage, thermal expansion and contraction stress damage, weak wind resistance, and corrosion resistance. Aluminum-magnesium-manganese metal roofs can solve these problems very well. The upright lock seam system is currently a more commonly used roofing system for light steel structure public buildings. There are many types of construction methods. The current commonly used method is: glass wool insulation layer, air barrier layer, glass wool sound absorption layer, non-woven fabric, perforated corrugated steel bottom plate, secondary purlin, main purlin or main steel structure are laid under the upright lock seam aluminum-magnesium-manganese alloy corrugated plate. This construction method can solve the functional requirements of the roof such as waterproofing, heat preservation, sound insulation, and sound absorption, but because the materials used are mostly flexible materials, the structural stability in windy weather is greatly reduced. The utility model patent with application number 202021352182.6 discloses a large-span upright lock-edge aluminum-magnesium-manganese plate metal roof structure, including purlins and color steel plates. Three groups of roof panels are arranged horizontally above the color steel plates, and two groups of fixed supports supporting the roof panels are arranged under adjacent roof panels. A longitudinally extending plum blossom head is fixed on the top of the support plate, which is connected to the joints of the roof panels through a snap-on lock-edge structure. There is no need to penetrate the roof panels with screws for installation. The entire roof panel system can expand and contract freely under temperature changes to avoid roof leakage and extend the life of the metal roof structure. However, the structure has poor wind resistance and relatively weak noise reduction ability. Utility Model Content
