Description

Technical Field

[0001] This utility model relates to a roof standing seam end cap system kit, and to a metal roofing system, belonging to the field of construction. Background Technology

[0002] Currently, large-span public buildings mostly adopt steel structures for their main structures, and the roofs generally use complex, multi-layered metal roofing systems. Metal roofing systems have been used in my country for nearly 30 years. As building designs become increasingly complex and taller, metal roofs face more and more challenges. They must not only meet aesthetic requirements but also possess stability to withstand complex weather conditions. Coastal cities, in particular, are subject to typhoon attacks, further increasing the demand for structural stability.

[0003] Metal roofing systems are mostly sloping and irregularly shaped. Standing seam roof panels typically have end caps to prevent moisture ingress and to conceal the internal structure, enhancing the appearance. Common end cap structures involve manually cutting and fabricating a metal sheet to fit the standing seam roof panel, then riveting or welding the sheet to the panel's end. This baffle prevents rainwater backflow during extreme weather conditions.

[0004] The existing technical solutions have the following drawbacks: metal plates are generally heavy and costly. Furthermore, if multi-point welding is used when installing metal plates, it is inconvenient to operate and disassemble them. If end-point welding is used, water leakage will occur due to insufficient tightness of the connection, resulting in poor waterproofing. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a roof standing seam end cap system kit and a metal roofing system to solve the above-mentioned problems.

[0022] Figure 2 This is an enlarged schematic diagram of the roof standing seam end cap system kit. Detailed Implementation

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a roof standing seam plug system kit, which includes: a down-turned edge waterproofing plate 1, a clamp 2, a plug 3, a metal water-blocking plate 5, and a down-turned edge waterproofing buckle cover 6.

[0025] The down-facing waterproofing board 1 is fixedly connected to the lower part of the roof edge. For example... Figure 2 As shown, the lower edge water-blocking plate 1 has an edge-sealing section 11, a water-blocking section 12, and a water-draining section 13.

[0026] The edge section 11 is snapped into the pressure clamp 2; the water-blocking section 12 is folded downward from the plane to prevent rainwater from flowing back and to divert it downward.

[0027] The drain section 13 is located at the end of the water-blocking section 12 and folds inward and upward. This further helps rainwater flow down and makes the edges smooth and non-exposed, preventing rust.

[0028] The down-turned edge waterproofing board 1 is riveted to the edge of the roof using rivets 14.

[0029] The end cap 3 is bonded to the roof base plate 20. In this embodiment, the end cap 3 is made of foam.

[0030] Fixture 2, such as Figure 2 As shown, it includes two sections: a fastener 21 on one side and a pressure clamp 22 on the other. The fastener 21 is fixed in the end cap 3. The fastener is forked to increase the firmness of the connection with the end cap 3. There are two pressure clamps 22, one opening upwards and the other downwards. The pressure clamp 22 with the downward opening engages with the edge banding section 11 to seal the edge of the metal roof.

[0031] The clamp 2 and the plug 3 are prefabricated in the factory and installed together.

[0032] Metal water-blocking plate 5 is longitudinally fixed to the edge of the roof. For example... Figure 2 As shown, the lower end of the metal water-blocking plate 5 is fixedly connected to the roof base plate 20 by screws 8. Screws 8 are self-tapping screws.

[0033] The flip-edge waterproofing cover 6 has one end locked to the upper part of the metal baffle plate 5, and the other end snapped into the upward-opening pressure clamp 22, so that it closes together with the lower flip-edge waterproofing plate 1 at the edge, thus completing the complete coverage of the roof edge.

[0034] like Figure 1 and Figure 2 As shown, this embodiment also provides a metal roofing system, which, in addition to the above-mentioned roof standing seam end cap system kit, also includes:

[0035] Metal profiled strips 4 have upward-curving pressing parts 41 on both sides. Multiple metal profiled strips 4 are connected to each other through the pressing parts to form a continuous roof. At the locking edge, the pressing parts 41 are engaged with the metal baffle 5, and are locked in the notched engagement point to fix them together.

[0036] The metal water barrier 5 is attached to the upward protruding edge 41 of the metal profiled strip 4 on the roof via the first bending section 51 at the top.

[0037] In a preferred embodiment, the roof base plate 20 has an additional waterproof layer, and the end cap 3 is adhered to the waterproof layer.

[0038] When installing the roof standing seam plug system kit, first use rivets 14 to connect the down-turned edge waterproofing plate 1 to the roof base plate to perform height difference water tightness test. After completion, use adhesive to fix the foam plug 3 to the metal roof base plate or TPO waterproofing layer. TPO refers to thermoplastic polyolefin. After checking the adhesion tightness, proceed with the installation of the metal roofing panels. Press down the foam plug 3, apply sealant to the surrounding gaps, and temporarily fix the metal profiled strip 4 to the metal roofing panel using weather-resistant sealant. Then, accurately press the metal baffle 5 to the position coinciding with the metal profiled strip 4, and secure it with self-tapping screws and circumferential rivets. Apply sealant to all contact points with the metal roofing panel. Next, install the flanged waterproofing cap 6, connecting its front end to the metal baffle 5 via a locking mechanism to complete the flanged waterproofing. The rear end, along with the lower flanged waterproofing cap 1, is pressure-pressed into the two pressure clamps at the tail of the galvanized clamp 2, completing the load-bearing fixation of the entire system. Finally, check for leaks and gaps in exposed areas and seal them tightly with sealant.

[0039] This utility model's roof sealing system features a simple structure and efficient installation. All metal materials are the same as those used in the roof panels, avoiding uneven stress and preventing oxidation. Furthermore, all major materials are custom-made to fit the roof panel profile, ensuring a tight and seamless seal. The down-turned edge waterproofing plate 1 is tightly connected to the roof, creating a complete water-tight seal and preventing water from seeping in through gaps. The end cap 3 is elastic and water-resistant, effectively isolating water. Only the metal water-stop plate 5 is nailed in place, eliminating the need for traditional welding, making operation simple and installation quick. The metal profiled strip 4 is temporarily fixed to the metal roof panel using weather-resistant sealant, strengthening the fixation and preventing nail holes. By installing the down-turned edge waterproofing cap 6, which connects to the metal water-stop plate 5 via a locking mechanism, the entire roof edge is completely sealed. No rigid fixing is required; the entire structure is formed simply by interlocking pressure.
