Description

Technical Field

[0001] This utility model relates to the field of wall panel construction technology, and in particular to a fusion plate metal roof panel overlapping structure. Background Technology

[0002] In modern building structures, metal roofing panels are widely used in roofing systems of various buildings due to their advantages such as lightweight, high strength, durability, and ease of construction and maintenance. However, traditional overlapping structures of metal roofing panels often have some problems, such as poor waterproofing performance, loosening or gaps at the overlaps, which in turn affect the stability and service life of the entire roofing system.

[0003] To address these issues, researchers have begun exploring and studying novel metal roof panel overlapping structures. One important direction for improvement is enhancing the roof's waterproofing performance and overall stability by optimizing the overlapping method and adding a waterproof layer. Against this backdrop, this invention proposes a fusion-plate metal roof panel overlapping structure, aiming to achieve better waterproofing and more stable structural performance through innovative overlapping design and material application.

[0004] Specifically, traditional metal roofing panels often use simple overlapping or bolt connections when overlapping. These methods are susceptible to environmental factors (such as wind pressure and temperature changes) over long-term use, leading to loosening or gaps at the overlaps and affecting the roof's waterproofing performance. Furthermore, traditional metal roofing panels often use a single paint or coating to enhance waterproofing and corrosion resistance, but these treatments often have limited lifespan and high maintenance costs. This invention, however, by covering the upper panel of the metal roofing panel with a TPO roll material layer, not only improves the roof's waterproofing performance but also enhances its weather resistance and lifespan, while reducing subsequent maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems existing in the prior art. The fusion plate metal roof panel overlapping structure of this utility model is based on the traditional metal roof panel overlapping structure. By designing a specific interlocking structure and TPO cap, it not only achieves a tight overlap between metal roof panels, but also further enhances the waterproof performance of the overlap, thereby improving the waterproof performance and overall stability of the roof.

[0006] This utility model is achieved through the following technical solution: a fusion plate metal roof panel overlapping structure, comprising multiple metal roof panels overlapping each other in the horizontal and vertical directions, the upper panel of the metal roof panels being covered with a TPO roll material layer, multiple corrugated protrusions arranged side by side in the horizontal direction on the metal roof panels, adjacent metal roof panels being stacked in the vertical direction, and adjacent metal roof panels being interlocked in the horizontal direction, the two ends of the metal roof panels in the horizontal direction being respectively provided with a first splicing part and a second splicing part that interlock with each other, the first splicing part and the second splicing part forming an interlocking structure, and a TPO cap being provided on the metal roof panel corresponding to the position above the interlocking structure.

[0007] To further optimize this utility model, the following technical solutions may be preferred:

[0008] Preferably, the cross-section of the wave-shaped protrusion is trapezoidal.

[0009] Preferably, the metal roof panel is a composite panel, which includes a first metal layer and a second metal layer, with a filler material layer disposed between the first metal layer and the second metal layer.

[0010] Preferably, reinforcing ribs are provided side by side on the first metal layer and the second metal layer, and the reinforcing ribs are arranged longitudinally.

[0011] Preferably, the first splicing part includes an insertion protrusion disposed at one end of the metal roof panel, and the second splicing part includes an insertion groove and a positioning bending plate disposed at the opposite end of the metal roof panel. The positioning bending plate overlaps on the corrugated protrusions on the adjacent metal roof panels, and the insertion groove and the insertion protrusion engage with each other.

[0012] Preferably, the end of the positioning bending plate is provided with a bending protrusion, and the corrugated protrusion on the metal roof panel opposite to the end of the positioning bending plate is provided with a positioning groove, and the positioning groove cooperates with the bending protrusion.

[0013] Preferably, the insertion protrusion and insertion slot are both formed by bending the second metal layer, and the positioning slot and positioning bending plate are both formed by bending the first metal layer.

[0014] Preferably, the snap-fit ​​structure is provided with an inverted U-shaped nailing component, which fixes two adjacent metal roof panels with fixing nails. The inner wall of the TPO cap is bonded to the top of the nailing component by a self-adhesive component, and the two sides of the TPO cap extend and overlap the TPO roll layer on the metal roof panel.

[0015] Preferably, the TPO roll layer on the metal roof panel has an extension in the longitudinal direction, and the extension extends downward to overlap the TPO roll layer of the adjacent metal roof panel.

[0016] This utility model has the following effects:

[0017] (1) Enhanced Waterproofing Performance: By designing a specific interlocking structure and covering the interlocking structure with a TPO cap, this invention achieves a tight overlap between metal roof panels. This design effectively prevents rainwater and other moisture from seeping in through the overlap, thereby significantly improving the waterproofing performance of the roof. Even under severe weather conditions, it ensures that the interior of the building remains dry.

[0018] (2) Improved overall stability: Adjacent metal roof panels are connected by interlocking and overlapping in the horizontal and vertical directions, respectively. This structure enhances the connection strength between the roof panels. Under the influence of external environmental factors such as wind pressure and temperature changes, the roof panels are less likely to loosen or develop gaps, thereby improving the overall stability and durability of the entire roof system.

[0019] (3) Optimized construction efficiency: The fusion plate metal roof panel overlapping structure of this utility model adopts a standardized design, making installation and disassembly during construction simpler and faster. Construction workers can more easily achieve precise alignment and fixing of the roof panels, thereby shortening the construction cycle and reducing construction costs.

[0020] (4) Extended service life: The TPO roll layer covering the metal roofing panel has excellent weather resistance and corrosion resistance, and can resist the erosion of harmful substances such as ultraviolet rays, acids and alkalis. At the same time, the interlocking structure and TPO cap design also reduce wear and aging at the joints, thereby extending the service life of the metal roofing panel.

[0021] (5) Enhanced Aesthetics: The undulating protrusions not only enhance the structural strength of the metal roof panels but also give the roof a more aesthetically pleasing appearance. This design makes the building visually more three-dimensional and layered, enhancing its overall aesthetics and value.

[0022] In summary, the fusion plate metal roof panel overlapping structure of this utility model exhibits significant advantages in terms of waterproof performance, overall stability, construction efficiency, service life, and aesthetics, providing a more reliable and efficient roofing solution for modern buildings.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0034] Example 1

[0035] like Figure 1-8As shown: A fusion panel metal roofing panel overlapping structure includes multiple metal roofing panels 1 that overlap each other in the horizontal and vertical directions. The upper panel of the metal roofing panel is covered with a TPO roll material layer 2. Multiple corrugated protrusions 3 are arranged side by side in the horizontal direction on the metal roofing panel. Adjacent metal roofing panels are stacked in the vertical direction and interlocked in the horizontal direction. The two ends of the metal roofing panel in the horizontal direction are respectively provided with a first splicing part 4 and a second splicing part 5 that interlock with each other. The first splicing part and the second splicing part form an interlocking structure. A TPO cap 6 is provided on the metal roofing panel above the position corresponding to the interlocking structure.

[0036] In a preferred embodiment, the cross-section of the corrugated protrusion 3 is trapezoidal. This shape not only increases the contact area of ​​the protrusion and improves the adhesion with the upper and lower layers, but also allows the protrusion to better disperse stress when subjected to external forces, avoiding damage caused by stress concentration. Therefore, the trapezoidal corrugated protrusion significantly enhances the structural stability of the metal roof panel, making it more resistant to external loads such as wind pressure and snow pressure.

[0037] In a preferred embodiment, the metal roof panel 1 is a composite panel comprising a first metal layer 101, a second metal layer 102, and a filler material layer 103 between the first and second metal layers. This design combines the strength of the metal material with the thermal insulation and sound insulation properties of the filler material, enabling the metal roof panel to maintain high strength while also possessing excellent thermal insulation, sound insulation, and fire resistance. This significantly improves the overall performance of the roof and meets the multifunctional needs of modern architecture.

[0038] In a preferred embodiment, reinforcing ribs 104 are provided side-by-side on the first metal layer 101 and the second metal layer 102, arranged longitudinally. This design significantly enhances the longitudinal strength of the metal roof panel, making it more resistant to longitudinal loads and deformations. Simultaneously, the reinforcing ribs also disperse stress, preventing damage caused by excessive local stress. Therefore, the addition of reinforcing ribs further improves the structural stability and durability of the metal roof panel.

[0039] In a preferred embodiment, the first splicing part 4 includes an insertion protrusion 105 disposed at one end of the metal roof panel, and the second splicing part 5 includes an insertion groove 106 and a positioning bending plate 107 disposed at the opposite end of the metal roof panel. The positioning bending plate overlaps the corrugated protrusions on the adjacent metal roof panels, and the insertion groove and the insertion protrusions engage with each other. This design ensures that the metal roof panels can be tightly connected in the lateral direction and are not easy to loosen. The positioning bending plate overlapping the corrugated protrusions on the adjacent metal roof panels not only increases the contact area of ​​the connection, but also further enhances the stability of the connection through physical fitting. The bent protrusions at the end of the positioning bending plate cooperate with the positioning grooves on the metal roof panels to form an additional locking mechanism, which effectively prevents the relative displacement of the roof panels when subjected to external forces.

[0040] In a preferred embodiment, the end of the positioning bending plate 107 is provided with a bending protrusion 108, and a positioning groove 109 is designed on the corrugated protrusion on the metal roof panel away from the positioning bending plate. Specifically, the positioning groove 109 is designed on the side of the corrugated protrusion away from the edge, and the positioning groove and the bending protrusion cooperate with each other. The interlocking structure of the insertion protrusion and the insertion groove, as well as the overlap of the positioning bending plate and the corrugated protrusion, together form a tight waterproof barrier, effectively preventing water from seeping in from the overlap gap. The cooperation between the positioning groove and the bending protrusion further enhances the waterproof effect, ensuring that the waterproof performance of the roof is not affected even under extreme weather conditions.

[0041] In a preferred embodiment, the insert protrusion 105 and the insert groove 106 are both formed by bending the second metal layer 102, and the positioning groove 109 and the positioning bending plate 107 are both formed by bending the first metal layer 101. The standardized design, where components such as the insert protrusion, insert groove, and positioning bending plate are all formed by bending metal layers, makes installation and disassembly during construction simpler and faster. Construction workers can more easily achieve precise alignment and fixing of the roof panels, reducing installation errors and improving construction efficiency and quality.

[0042] Furthermore, the above design optimizes the connection structure, reducing wear and aging at the joints, thereby extending the service life of the metal roof panels; the placement of positioning bends and bending protrusions also increases the strength of the connection points, making the entire roof system more durable; the design of components such as insert protrusions, insert slots, and positioning bends not only enhances the stability of the connection but also makes the roof visually cleaner and more aesthetically pleasing; the combination of wave-shaped protrusions and positioning bends also helps with drainage and ventilation, improving the functionality of the roof.

[0043] As a preferred embodiment, the interlocking structure is provided with an inverted U-shaped nail 7. The nail 7 is used to fix two adjacent metal roof panels with fixing nails 8. The inner wall of the TPO cap 6 is bonded to the top of the nail 7 with a self-adhesive 9. The TPO cap extends on both sides and overlaps the TPO roll layer on the metal roof panel. The TPO roll layer 2 on the metal roof panel has an extension 10 in the longitudinal direction. The extension extends downward and overlaps the TPO roll layer 2 of the adjacent metal roof panel. The above structural design has the following advantages: (1) Enhanced fixing stability: By providing an inverted U-shaped nail 7 on the interlocking structure and using fixing nails to fix two adjacent metal roof panels, this design ensures a more secure connection between the roof panels. The nail 7 not only provides additional support, but also achieves deeper fixing by penetrating the roof panel and the TPO roll layer, effectively preventing the roof panel from loosening or shifting when subjected to external forces. (2) Optimized Waterproof Sealing: The inner wall of the TPO cap is bonded to the top of the nailer via self-adhesive. This design not only simplifies the installation process but also ensures a tight fit between the cap and the nailer. Simultaneously, the TPO cap extends and overlaps the TPO roll layer on both sides of the metal roof panel, forming a continuous waterproof barrier that effectively prevents moisture from seeping in through the overlap gaps. The longitudinal extension of the TPO roll layer on the metal roof panel further enhances the waterproofing effect. The extension extends downwards and overlaps the TPO roll layer of the adjacent metal roof panel, forming an overlapping waterproof layer that ensures the roof's waterproofing performance remains unaffected even under extreme weather conditions. (3) Improved Construction Efficiency and Precision: The inverted U-shaped nailer and self-adhesive design make fixing and sealing during construction simpler and faster. Construction workers can more easily achieve precise alignment and fixing of the roof panels, reducing installation errors and improving construction efficiency and quality. (4) Enhanced structural durability and service life: By optimizing the connection structure and waterproofing design, wear and aging at the joints are reduced, thereby extending the service life of the metal roofing panels and TPO rolls. Meanwhile, the robust design of the fasteners and TPO caps also increases the overall durability of the roofing system. (5) Improved aesthetics and functionality: The TPO cap design not only enhances waterproofing performance but also makes the roof visually cleaner and more aesthetically pleasing. Furthermore, the tight fit between the extended portion of the cap and the TPO roll layer avoids visual imperfections caused by exposed fasteners; the extension not only enhances waterproofing but also facilitates drainage and ventilation, improving the functionality of the roof.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
