Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of metal roofing structure systems, and more specifically, to an angle-seam type corrosion-resistant profiled steel sheet roofing system. Background Technology
[0002] In the field of building metal roofing, corrosion-resistant profiled steel sheets are widely used due to their excellent durability. Traditional corrosion-resistant profiled steel sheets typically use galvanized steel as the core material, with a modified bitumen polymer layer and a pre-coated aluminum foil protective layer on both the inner and outer surfaces, forming a five-layer composite structure. This is manufactured through continuous hot-pressing and roll forming processes. Because of the relatively soft modified bitumen polymer layer inside, it is difficult to form overly complex edge-locking shapes during roll forming, and most are processed into relatively simple corrugated sheet shapes. To fix them to the roof purlins, the industry commonly uses self-tapping screws combined with waterproof gaskets.
[0003] This method of fixing roof panels using self-tapping screws inevitably creates numerous perforations. Although waterproof gaskets provide sealing, these perforated areas remain weak points in the roof waterproofing system, posing a potential risk of leakage. Over time, or after exposure to environmental factors such as temperature variations and wind loads, the gaskets may age and fail, leading to a decline in the roof's waterproofing performance. Therefore, this type of penetrating fixing roofing system in existing technology has inherent limitations in its waterproofing performance. The industry urgently needs a roof fixing solution that does not penetrate the roof panel itself, while maintaining the excellent properties of corrosion-resistant steel and providing reliable wind resistance. Utility Model Content
[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes an angle-seam type corrosion-resistant profiled steel roofing system, which can overcome the above-mentioned shortcomings of the prior art.
[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:
[0006] An angle-seam type corrosion-resistant profiled steel roofing system;
[0007] The angle-seam corrosion-resistant profiled steel roofing system includes angle-seam corrosion-resistant profiled steel sheets, stainless steel roof supports, roof purlins, windproof clamp assemblies, and self-tapping screws. The stainless steel roof supports are fixed to the roof purlins by self-tapping screws. The angle-seam corrosion-resistant profiled steel sheets have inner and outer flanges. The inner flange is fastened to the top of the stainless steel roof supports, and the outer and inner flanges of adjacent steel sheets are engaged with each other by a locking mechanism. The windproof clamp assembly is installed at the ribs after locking and includes profile windproof clamps, grooved pads, and hexagonal socket head cap screws. The hexagonal socket head cap screws pass through the profile windproof clamps and are inserted into the grooves of the grooved pads. Tightening the hexagonal socket head cap screws clamps the profile windproof clamps and grooved pads to the adjacent ribs.
[0008] Furthermore, the outer and inner flanges of adjacent angle-seam corrosion-resistant profiled steel sheets are mechanically interlocked and locked at the position of the stainless steel roofing support using a special locking machine.
[0009] Furthermore, the grooved pad of the windproof clip assembly can be replaced with an aluminum profile with an installation platform; the aluminum profile is provided with two bolt mounting slots, which are connected to the external corner aluminum profile keel by mounting bolts, for expanding the installation of roof auxiliary facilities.
[0010] Furthermore, the aluminum profile is fastened to the angle aluminum profile keel by mounting bolts, and the roof auxiliary facilities include at least one of a fall protection system, a walkway system, a snow blocking system, or an aluminum plate secondary skin system.
[0011] Furthermore, the angle-seam corrosion-resistant profiled steel sheet has a five-layer composite structure, including a galvanized steel core, a modified asphalt polymer layer, and a pre-coated aluminum foil protective layer.
[0012] Furthermore, the top of the stainless steel roof support is provided with a fastening structure that matches the shape of the inner flange of the angled corrosion-resistant profiled steel sheet.
[0013] Furthermore, the inner side of the profile windproof clip is provided with anti-slip teeth to enhance the frictional engagement force with the plate ribs.
[0014] Furthermore, the tightening stroke of the internal hexagonal set screw controls the clamping distance between the profile windproof clamp and the grooved pad, and its maximum clamping distance is less than 1.2 times the total thickness of the adjacent plate ribs.
[0015] Furthermore, after the self-tapping screw penetrates the stainless steel roof support and roof purlin, its end is coated with a layer of sealant.
[0016] The beneficial effects of this utility model are as follows: By adopting an angle-locking edge fixing method to replace the traditional through-fixing, the roofing system completely avoids penetration points caused by nailing, eliminating the risk of leakage caused by traditional fixing methods and improving the overall waterproof performance of the roof. Through the specially designed windproof clip components and the structure that can be replaced with aluminum profiles with installation platforms, the roofing system has stronger wind uplift resistance and is easy to expand and install auxiliary facilities such as fall arrest systems, walkway systems, snow blocking systems, photovoltaic systems or aluminum panel secondary skin systems. In this way, while improving waterproof and corrosion resistance, the reliability, safety and functional applicability of the roofing system are greatly improved, meeting the diverse building needs.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.
[0041] In practical use, the angle-seam type corrosion-resistant profiled steel roofing system according to this utility model consists of an angle-seam type corrosion-resistant profiled steel sheet 1, a stainless steel roof support 2, a roof purlin 3, a windproof clamp assembly 4, and self-tapping screws 5, and is edged using a special edge-locking machine.
[0042] The installation process is described below:
[0043] Step 1: Fix the stainless steel roof support 2 to the roof purlin 3 with self-tapping screws 5; fasten the stainless steel roof support 2 to the inner flange 11 of the angle-seam corrosion-resistant profiled steel sheet 1.
[0044] Step 2: Attach the outer flange 12 of the next angle-seam corrosion-resistant profiled steel sheet 1 to the stainless steel roof support 2, and install and fix the next stainless steel roof support 2 at the inner flange 11 position of the next angle-seam corrosion-resistant profiled steel sheet 1.

[0050] In summary, by employing the above-mentioned technical solution of this utility model, the roofing system completely avoids penetration points caused by nailing by using an angle-locking edge fixing method instead of traditional through-fixing, thus eliminating the risk of leakage caused by traditional fixing methods and improving the overall waterproof performance of the roof. Through specially designed windproof clip components and a structure that can be replaced with aluminum profiles with installation platforms, the roofing system has stronger wind uplift resistance and facilitates the expansion and installation of auxiliary facilities such as fall arrest systems, walkway systems, snow blocking systems, photovoltaic systems, or aluminum panel secondary skin systems. This achieves the goal of significantly improving the reliability, safety, and functional applicability of the roofing system while enhancing its waterproof and corrosion-resistant properties, thereby meeting diverse building needs.
