Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal roofing technology, specifically to a modular metal roofing structure. Background Technology
[0002] Metal roofing structures are commonly used in large-scale composite steel structure buildings. With social development and technological advancements, the requirements for wind resistance and waterproofing performance of metal roofing structures are becoming increasingly stringent to ensure a longer service life. However, existing metal roofing panels have poor wind pressure resistance, especially at the joints, where they are prone to deformation due to weak connections. Furthermore, existing metal roofing panels lack sufficient waterproofing, with poor sealing at the joints between adjacent panels, leading to leaks, seepage, or rainwater backflow. Temperature changes cause metal roofing panels to expand or contract, resulting in cracks or deformation, further reducing waterproofing performance. Additionally, to ensure the comfort and safety of residents in large steel structure buildings, metal roofing structures also need to possess flame-retardant, sound-insulating, and thermal-insulating properties. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A modular metal roof structure is provided, comprising a plurality of sequentially spliced metal roof panels. Each metal roof panel has an integrally formed vertical rib at both ends. A first arc-shaped clamping plate and a second arc-shaped clamping plate are respectively provided on the top of the vertical ribs at both ends. The first arc-shaped clamping plate and the second arc-shaped clamping plate on two adjacent metal roof panels are adjacent to each other, and the first arc-shaped clamping plate is fixedly sleeved on the second arc-shaped clamping plate. The second arc-shaped clamping plate is fixedly sleeved on the top of the support. A plurality of supports are installed at intervals on the roof support grid. The plurality of first arc-shaped clamping plates are connected by windproof components.
[0006] Furthermore, the cross-sections of both the first and second arc-shaped cards are circular hook-shaped, and the inner arc surface of the first arc-shaped card matches the outer arc surface of the second arc-shaped card.
[0007] Furthermore, the top of the support is provided with a protrusion to facilitate the fixed installation of the second arc-shaped clamping plate.
[0008] Furthermore, several curved ribs are spaced apart in the middle of the metal roof panel.
[0009] Furthermore, the metal roof panels and the vertical ribs are smoothly connected by an integrally molded corrugated plate.
[0010] Furthermore, a roof base plate is installed on the supporting space frame, and the supports are fixedly installed on the roof base plate by purlins. From the inside to the outside, an inner isolation layer, an air barrier layer, a thermal insulation layer, a waterproof layer, and an outer isolation layer are installed between the roof base plate and the metal roof panel.
[0011] Furthermore, the inner and outer isolation layers are made of 50mm and 25mm ultra-fine glass fiber cotton, respectively; the air barrier layer is made of 0.3mm polypropylene plastic veneer; the insulation layer includes two layers of staggered water-repellent rock wool, each 50mm thick; and the waterproof layer is made of 1.5mm polyester fiber.
[0012] Furthermore, the metal roofing panels are made of 1mm thick aluminum-magnesium-manganese alloy.
[0013] Furthermore, the windproof component includes a windproof connecting rod, on which several pairs of windproof clips are connected by bolts, and each pair of windproof clips is fastened to the first arc-shaped clamping plate by bolts.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. In this scheme, several metal roof panels are sequentially spliced and fixed to the supports through the first and second arc-shaped clamps at their ends. This method is convenient to construct and the splices are not prone to water seepage. The corrugated plates enhance the toughness and wind pressure resistance of the vertical ribs, and have good arc-forming performance, making them aesthetically pleasing and practical. The arc-shaped ribs provide a certain deformation space for the thermal expansion and contraction of the metal roof panels. Finally, the several metal roof panels are fixedly connected into a whole by windproof connecting rods, thereby improving the overall wind pressure resistance and deformation resistance of the metal roof structure.
[0016] 2. This solution achieves sound insulation, fireproofing, air insulation, heat insulation, and waterproofing by sequentially installing an inner isolation layer, an air barrier layer, a thermal insulation layer, a waterproof layer, and an outer isolation layer between the roof base plate and the metal roof panel, thereby improving the comfort and safety of the metal roof structure during use.
