Description

Technical Field

[0001] This utility model relates to the field of building metal roofing cladding systems, specifically to a multi-linked metal roofing panel rib. Background Technology

[0002] Traditional metal roofing systems connect adjacent metal panels using techniques such as single-edge rolling, interlocking, and welding to form a unified panel system. Since metal roofing panels typically have a wave height of 50–80 mm and a width of 400–500 mm, they are formed by cold-bending and pressing thin-walled metal sheets of 0.5–0.8 mm. On the one hand, the effective cross-section of the profiled roofing panel needs to be reduced due to the width-to-thickness ratio of the thin-walled steel sheet; on the other hand, the connection between two adjacent panels is relatively weak, failing to form an integral load-bearing cross-section. Therefore, metal roofing panels have relatively weak load-bearing capacity under wind loads. Simultaneously, with the widespread application of distributed photovoltaic (PV) power generation systems on metal roofs, PV modules need reliable connections to the metal roofing panel ribs. Generally, PV modules are connected to the roofing panel ribs via point connectors. The wind or snow loads on the PV modules are transferred to the metal roofing panel ribs as concentrated forces. This places a greater load on traditional metal roofing panels, requiring them to withstand larger concentrated loads. Therefore, higher requirements are placed on the overall bending load-bearing capacity and local load-bearing capacity of metal roofing panels. Utility Model Content

[0003] This utility model discloses a multi-linked metal roof panel rib, which longitudinally connects two adjacent metal roof panel ribs through a multi-linked structure, forming a combined stress-bearing section between the two thin-walled profiled metals, increasing the effective cross-section, thereby improving the overall bending load-bearing capacity and local stress-bearing capacity of the metal roof panel, and enhancing the wind resistance performance of the metal roof panel.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-linked metal roof panel rib includes interconnected metal roof panels and a first roof support disposed between the interconnected metal roof panels. The side connecting ends of the metal roof panels form protruding ribs, each rib including an upper rib edge and a lower rib edge. A rib protrusion extending inward toward the metal roof panel is formed between the upper and lower rib edges, and a cavity is formed inside the rib protrusion. The rib protrusion is open on the side away from the metal roof panel. The first roof support includes a first support base and a first support connecting piece fixedly connected to the first support base. First horizontal constraint plates are respectively provided on both sides of the first support connecting piece.

[0006] The ribs of two connected metal roof panels are joined together, and the convex ribs of the two metal roof panels are joined together to form a rib groove. The first support base is fixed on the roof steel purlin. The first horizontal constraint plate on the first support connecting piece is embedded in the rib groove. The upper ribs of the two metal roof panels are connected to each other, and the lower ribs are connected to each other. The interconnection of the lower ribs is located on both sides of the first roof support. A sliding cavity is formed between the interconnection of two adjacent lower ribs. Within the sliding cavity, the first support connecting piece and the rib groove can slide relative to each other.

[0007] Furthermore, the upper ribs are connected by continuous edge-rolling and interlocking along the length of the ribs, and the two upper ribs are welded together by continuous welds along the length; the lower ribs are connected by intermittent welds along the length.

[0008] Furthermore, the upper ribs are connected by continuous rolled edge interlocking along the length of the ribs, and the two upper ribs are welded together by continuous weld along the length; the lower ribs are connected by bolts with waterproof washers at intervals along the length or by resistance spot welding.

[0009] Furthermore, the upper ribs are connected by continuous rolled edge interlocking along the length of the ribs, and the lower ribs are connected by bolts with waterproof washers spaced apart along the length or by resistance spot welding.

[0010] Furthermore, the outermost rib of the metal roof panel located at the outermost edge is connected to the second roof support. The second roof support includes a second support connecting piece and a second support base. The second support connecting piece is provided with a second horizontal constraint plate, which is embedded in the inner cavity of the rib protrusion of the metal roof panel. The second support base is fixed to the roof steel purlin. The second support connecting piece and the second support base can slide relative to each other. The second support connecting piece is fixedly connected to the upper rib edge of the metal roof panel.

[0011] Furthermore, the outermost rib of the metal roof panel located at the outermost edge is connected to the second roof support. The second roof support includes a second support connecting piece and a second support base. The second support connecting piece is provided with a second horizontal constraint plate, which is embedded in the inner cavity of the rib protrusion of the metal roof panel. The second support base is fixed to the roof steel purlin. The second support connecting piece and the second support base can slide relative to each other. The second support connecting piece is fixedly connected to the lower rib edge of the metal roof panel.

[0012] Furthermore, the second support connecting piece is bolted to the upper rib or the lower rib respectively.

[0013] This invention connects the interconnected metal roof panel ribs in multiple longitudinal directions, improving the reliability of the connection between adjacent metal roof panels, increasing the effective cross-section for bending bearing capacity, and enhancing the safety and reliability of the metal roof panels under wind loads and local concentrated forces.

[0014] This invention connects the lower parts of the interconnected metal roof panel ribs with bolts or intermittent welds, avoiding the interrupted setting of the roof support connection section. This maintains the combined connection function of the ribs without affecting the relative expansion and contraction sliding performance of the metal roof panel and the roof support.

[0015] This utility model changes the out-of-plane stress on the longitudinal edge and support connection points of the metal roof panel by adding a reliable connection to the bottom of the metal roof panel ribs. The out-of-plane stress is directly transferred through the bottom connection, which solves the wind load damage caused by the detachment of the roof support connection due to out-of-plane deformation.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0046] This embodiment provides a multi-link connection scheme for the rib connection of metal roof panels. The scheme involves the connection between metal roof panels 1, as well as the connection between metal roof panels 1 and roof supports. To distinguish the roof supports in different locations, this embodiment refers to the roof support located between two metal roof panels 1 as "first roof support 2" (see...). Figure 10 The roof support located on the outermost edge of the metal roof panel 1 is called the "second roof support 3" (see...). Figure 15 and Figure 17 ).

[0047] The structure of the first roof support 2 is as follows: Figure 12 As shown, the first roof support 2 includes a first support base 22 and a first support connecting piece 21. The first support connecting piece 21 is perpendicular to the first support base 22 and is integrated with it. First horizontal constraint plates 211 are formed by extending outward horizontally on both sides of the first support connecting piece 21. The first horizontal constraint plates 211 are perpendicularly connected to the first support connecting piece 21. Fixing holes are provided on the first support base 22.

[0048] The structure of the second roof support 3 is as follows: Figure 19 As shown, the second roof support 3 includes a second support connecting piece 31 and a second support base 32. The second support base 32 has a sliding groove, and a fixing hole is formed on the side of the sliding groove. The second support connecting piece 31 has a second horizontal constraint plate 311, which is perpendicularly connected to the second support connecting piece 31. The bottom of the second support connecting piece 31 has a limiting rod, and the bottom of the second support connecting piece 31 is embedded in the sliding groove of the second support base 32, allowing the second support connecting piece 31 to slide along the length of the sliding groove.

[0049] Structural reference for metal roofing panel 1 Figure 1 and Figure 2 As shown, the two opposite sides of the metal roof panel 1 form protruding ribs as connecting ends. The ribs include an upper rib 11 and a lower rib 12. A rib protrusion 14 extending inward toward the metal roof panel 1 is formed between the upper rib 11 and the lower rib 12. The rib protrusion 14 is curved and has a cavity inside. The side of the rib protrusion 14 away from the metal roof panel 1 is open.

[0050] Regarding the connection methods between the metal roof panels 1 given above, this utility model only provides the following three specific embodiments for illustration. However, the protection scope of this utility model is not limited to the solutions of the three specific examples. Any substitution or modification using conventional technical means shall fall within the protection scope of this utility model.

[0051] Example 1: As Figures 1 to 3 ,as well as Figure 10 and Figure 11 As shown, the connecting end ribs of two metal roof panels 1 are joined together. Multiple first roof supports 2 are spaced apart along the length of the ribs between the two metal roof panels 1, and the bases 22 of the first supports are bolted to the roof purlins 8. The rib protrusions 14 between the two metal roof panels 1 are joined together to form a rib groove 13, allowing the first horizontal constraint plate 211 of the first roof support 2 to be embedded in the rib groove 13. After the two metal roof panels 1 are joined, the upper rib edges 11 of the two metal roof panels 1 are welded together with a continuous weld 4 along the length of the ribs, and the top edges 15 of the upper rib edges 11 of the two metal roof panels 1 are continuously rolled together along the length of the ribs. In this embodiment, the lower rib edges 12 of the two metal roof panels 1 are connected by intermittent welds 5 formed by intermittent welding along the length of the ribs. The location of each intermittent weld 5 avoids the location of the first roof support 2, such as... Figure 1 As shown, a sliding cavity 7 is formed between adjacent intermittent welds 5, as... Figure 14 As shown, within the sliding cavity 7 range a, the first support connecting piece 21 can slide relative to the plate rib groove 13.

[0052] Example 2: The solution adopted in this example is as follows Figures 4 to 6 As shown, the difference between this embodiment and Embodiment 1 is that the lower ribs 12 of the two metal roof panels 1 are connected by bolts 6 with waterproof washers 9 spaced apart along the length of the ribs. Unless otherwise specified, all aspects in this embodiment are performed in the same manner as in Embodiment 1. Of course, resistance spot welding can also be used instead of the bolt connection method used in this embodiment. In this embodiment, the range a of the sliding cavity 7 is as follows... Figure 13 As shown.

[0053] Example 3: The solution adopted in this example is as follows Figures 7 to 9 As shown, the difference between this embodiment and Embodiment 2 is that the upper ribs 11 of the two metal roof panels 1 are connected only by continuous rolled edges 15 along the length of the ribs, without the need for continuous welds 4. The connection method of the lower ribs 12 and other aspects not specifically described in this embodiment are performed in accordance with Embodiment 2.

[0054] The above three specific embodiments illustrate the connection structure between two adjacent metal roof panels 1. For the metal roof panel 1 located at the outermost edge of the roof, its outer ribs are connected via a second roof support 3. The connection between the edge metal roof panel ribs and the second roof support 3 can be achieved in the following two ways:

[0055] Form 1: such as Figure 15 and Figure 16 As shown, the second support base 32 of the second roof support 3 is fixed to the roof steel purlin 8 with bolts, and the second support connecting piece 31 is fixed to the upper rib edge 11 of the metal roof panel 1 with bolts 6, so that the second horizontal constraint plate 311 is embedded into the cavity of the plate rib protrusion 14.

[0056] Form 2: such as Figure 17 and Figure 18 As shown, the second support base 32 of the second roof support 3 is fixed to the roof steel purlin 8 with bolts, and the second support connecting piece 31 is fixed to the lower rib edge 12 of the metal roof panel 1 with bolts 6, so that the second horizontal constraint plate 311 is embedded into the cavity of the plate rib protrusion 14.

[0057] This invention incorporates multiple longitudinal connections between the ribs of the metal roof panel, enhancing the reliability of the connections between the metal roof panels. For the connection points of the lower rib edge 12 of the metal roof panel 1, the connection is intermittently arranged, avoiding the location of the second roof support 2. This maintains the combined connection of the ribs while utilizing the sliding cavity 7 to provide space for free expansion and contraction between the second roof support 2 and the metal roof panel ribs. For the second roof support 3 connected to the outermost metal roof panel rib, the second support connecting piece 31 is fixedly connected to the rib, allowing the second support connecting piece 31 to freely expand and contract relative to the second support base 32 along the length of the rib. This structural design ensures that the metal roof panel 1 can freely expand and contract along the length of the rib under the influence of thermal expansion and contraction, thus releasing the temperature stress of the metal roof panel 1. The solution provided by this invention comprehensively improves the wind resistance of the metal roof panel 1.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
