Description

Technical Field

[0001] This utility model relates to roof structures, specifically to a metal roof structure. Background Technology

[0002] Industrial plants are often used as machine repair workshops, coal storage sheds, and warehouses in coal mines. These plants are relatively simple in design, often failing to adequately consider the local maximum wind pressure. Inadequate design of the fastening force between the metal roof panels and mounting brackets, as well as the spacing of the brackets, leads to damage or collapse of the metal roof under strong winds. If the plant houses precision equipment and battery manufacturing materials, the wind resistance requirements for the roof are significantly increased. Therefore, it is necessary to improve the wind resistance of the roof to ensure its durability and longer service life. Summary of the Invention

[0003] This invention addresses the technical problem of poor wind resistance in simple, traditional metal roofs by providing a metal roof structure.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a metal roof structure, comprising, from bottom to top, main purlins, profiled steel sheet bearing plates, purlins, a waterproof layer, an isolation layer, and an outer profiled metal sheet; a thermal insulation layer is laid at the purlins; a vapor barrier layer is laid on the side of the profiled steel sheet bearing plate near the purlins; a fixing bracket is fixed between the outer profiled metal sheet and the waterproof layer, the top of the fixing bracket being above the outer profiled metal sheet, and the lower end of the fixing bracket passing through the isolation layer. The purlin is fixed with screws; a heat insulation pad is laid between the waterproof layers of the fixing bracket; the profiled steel sheet bearing plate has multiple evenly distributed recessed connecting grooves, and is connected to the main purlin with screws at the recessed connecting grooves; a channel steel-shaped support is provided between adjacent recessed connecting grooves, with the two vertical ends of the support located at two adjacent recessed connecting grooves respectively, and the horizontal end of the support located between the lower end of the purlin and the vapor barrier layer; the purlin, the support, and the profiled steel sheet bearing plate are connected together with screws.

[0005] Furthermore, the outer laminated metal plate is coated with a 0.8mm thick fluorocarbon coating.

[0006] Furthermore, the waterproof layer is a 1.5mm thick TPO waterproof membrane.

[0007] Furthermore, the thermal insulation layer is 100mm thick 140K thermal insulation rock wool.

[0008] Furthermore, the bearing plate of the profiled steel sheet is a 0.8mm thick YX15 / 225 / 900 type profiled steel sheet.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The material and structural design of this invention gives the metal roof better wind resistance. By optimizing the spacing of the self-tapping screws, it not only increases pull-out resistance but also provides insulation and leak prevention. The structure is simple and saves on steel consumption. At the same time, it reduces rework costs and economic losses, achieving an industry-leading level. Attached Figure Description
