Abstract
Description
Technical Field
[0001] This invention relates to the field of building roofs, and more specifically, to a highly wind-resistant, leak-proof concealed roofing system. Background Technology
[0002] In the field of industrial plants and photovoltaic installations, roof panel systems are the core structure for ensuring building safety and functional stability. Traditional roof panel systems mostly use exposed screws to fix the panel units. Although this design simplifies the construction process, it has significant drawbacks: when encountering strong winds, the panel units at the exposed screws will form tearing points due to stress concentration, leading to a sharp decline in wind resistance and even safety hazards such as panel tearing and detachment. At the same time, the joint gaps at the screw fixing points are prone to becoming channels for rainwater leakage under wind and rain erosion. Long-term leakage not only damages equipment inside the plant and corrodes the steel structure, but also accelerates the insulation aging of photovoltaic modules, increasing maintenance costs and downtime risks.
[0003] This application provides a roof panel system that meets the requirements for wind resistance and leak prevention of roof panels. Summary of the Invention
[0004] 1. Technical problems to be solved
[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a high wind-resistant and leak-proof concealed roofing system that can improve the wind resistance and leak-proof performance of roof panels.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A highly wind-resistant and leak-proof concealed roofing system includes multiple unit roof panels and horseshoe buckles. One end of each unit roof panel is bent to form a snap-fit portion, and the side of the unit roof panel away from the snap-fit portion is bent to form a raised portion. Multiple horseshoe buckles are snapped into the snap-fit portion, and the horseshoe buckles are fixedly connected to the purlins by self-tapping screws. The horseshoe buckles snapped into the unit roof panels are located within the raised portions of adjacent unit roof panels.
[0009] The unit roof panel includes a metal substrate and a thermoplastic sheet that is hot-melt fixed to the outer surface of the metal substrate. One end of the thermoplastic sheet away from the snap-fit portion extends to the outer side of the inner metal substrate to form a protrusion. The protrusion of the unit roof panel and the portion of the adjacent unit roof panel located between the snap-fit portion and the raised portion are hot-melt fixed to form a welded strip.
[0010] As a further improvement of the present invention, the middle part of the raised portion is bent inward to form a concave portion, and a pulling component is engaged in the concave portion, with the lower end of the pulling component being engaged with a horseshoe buckle.
[0011] As a further improvement of the present invention, the traction assembly includes an upper clamp that engages with the concave portion, a sliding rod that is fixedly connected to the lower end of the upper clamp, the sliding rod that slides through the lower clamp, and the lower end of the lower clamp engaging with a horseshoe buckle.
[0012] As a further improvement of the present invention, the cross-section of the snap-fit part is U-shaped, the cross-section of the raised part is trapezoidal or semi-circular, and the horseshoe buckle is provided with a snap-fit cavity for the snap-fit part to be inserted.
[0013] As a further improvement of the present invention, the metal substrate is made of aluminum-zinc plate, the thermoplastic plate is made of thermoplastic polyolefin elastomer or polyvinyl chloride, and the horseshoe buckle is made of aluminum alloy material.
[0014] As a further improvement of the present invention, the horseshoe buckle includes a fixing plate, a pair of oppositely arranged side plates are fixedly connected to the fixing plate, a snap-fit cavity is opened on the side plate, the fixing plate abuts against the purlin and has a plurality of screw holes for self-tapping screws to pass through, and an abutting plate is fixedly connected to the side of the side plate away from the fixing plate, and the abutting plate abuts against the horizontal part of the unit roof panel located between the snap-fit part and the raised part.
[0015] As a further improvement of the present invention, the concave section is U-shaped, the upper clamp is a semi-enclosed structure and is sleeved on the outside of the concave section, and a pair of snap-fit posts are fixedly connected to the outer wall of the lower clamp, and a pair of snap-fit holes are opened on the horseshoe buckle to engage with the snap-fit posts.
[0016] As a further improvement of the present invention, the sliding rod is a round rod with an inverted T-shaped cross-section, and a spring is sleeved on the sliding rod. The upper end of the spring abuts against the lower end face of the upper clamp, and the lower end of the spring abuts against the upper end face of the lower clamp. The cross-section of the lower clamp is an inverted lantern shape, and the cross-section of the horseshoe buckle is a trapezoid with the tip pointing upwards.
[0017] 3. Beneficial Effects
[0018] Compared with the prior art, the advantages of this invention are:
[0019] (1) The present invention provides a unit roof panel with a snap-fit part and a raised part. When the snap-fit part of the unit roof panel is snapped and fixed by using horseshoe buckles and self-tapping screws, the horseshoe buckles and self-tapping screws are located in the raised part of the adjacent unit roof panel, thereby realizing the concealed installation of horseshoe buckles and self-tapping screws and improving the waterproofness, weather resistance and wind resistance of the roof panel.
[0020] (2) The present invention uses a horseshoe buckle to replace the self-tapping screws to directly penetrate the unit roof panel, thereby reducing stress concentration and further improving the wind resistance of the unit roof panel.
[0021] (3) The present invention uses a unit roof panel with a two-layer structure including a metal substrate and a thermoplastic board. The unit roof panel is fixedly connected to the adjacent unit roof panel by hot-melt fixing at the end away from the snap-fit part, so that the thermoplastic board on the outer surface is connected to form an integral waterproof layer. This not only makes it easier to adjust the hot-melt position and improves the installation flexibility, but also further improves the overall waterproof effect.
[0022] (4) By providing a snap-fit part and a raised part, the present invention improves the elastic deformation capability of the unit roof panel, thereby improving the roof panel's resistance to thermal expansion and contraction.
[0023] (5) The present invention provides a traction component that connects the horseshoe buckle and the raised part of the adjacent unit roof panel, as well as a concave part set in the middle of the raised part. When the raised part moves outward under the action of wind force, the traction component pulls the raised part, thereby further improving the overall wind resistance of the roof panel.
[0024] (6) The present invention provides a traction assembly including an upper clamp and a lower clamp, which enables the rapid splicing and installation of the traction assembly, the inner recess and the horseshoe buckle, thereby improving the convenience of installing multiple traction assemblies.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0039] Please see Figures 1-6In the first embodiment of the present invention, a high wind-resistant and leak-proof concealed roof system includes multiple unit roof panels 1 and horseshoe buckles 2. One end of the unit roof panel 1 is bent to form a snap-fit portion 101, and the side of the unit roof panel 1 away from the snap-fit portion 101 is bent to form a raised portion 102. Multiple horseshoe buckles 2 are snapped into the snap-fit portion 101, and the horseshoe buckles 2 are fixedly connected to the purlins 4 by self-tapping screws 3. The horseshoe buckles 2 snapped into the unit roof panel 1 are located in the raised portion 102 of the adjacent unit roof panel 1.
[0040] Please see Figure 4 and Figure 5 The unit roof panel 1 includes a metal substrate 103 and a thermoplastic sheet 104 that is hot-melt fixed to the outer surface of the metal substrate 103. One end of the thermoplastic sheet 104 away from the snap-fit portion 101 extends to the outer side of the inner metal substrate 103 to form a protrusion. The protrusion of the unit roof panel 1 is hot-melt fixed to the portion of the adjacent unit roof panel 1 located between the snap-fit portion 101 and the raised portion 102, and a welded strip 105 is formed.
[0041] Compared to traditional roofing systems, this invention, through the use of unit roof panels 1 with snap-fit portions 101 and raised portions 102, allows for concealed installation of the snap-fit portions 101 of the unit roof panels 1 when using horseshoe buckles 2 and self-tapping screws 3 to snap and fix them. The horseshoe buckles 2 and self-tapping screws 3 are located within the raised portions 102 of adjacent unit roof panels 1, improving the waterproofness, weather resistance, and wind resistance of the roof panels. Simultaneously, by using horseshoe buckles 2 to snap onto the snap-fit portions 101 instead of self-tapping screws 3 directly penetrating the unit roof panels 1, stress concentration is reduced, further enhancing the performance of the unit roof panels. The wind resistance of panel 1 is improved. In addition, the unit roof panel 1, which includes a two-layer structure of metal substrate 103 and thermoplastic panel 104, is fixedly connected to the adjacent unit roof panel 1 by heat fusion at the end of the unit roof panel 1 away from the snap-fit part 101. This allows the thermoplastic panel 104 on the outer surface to be connected to form an integral waterproof layer, which not only facilitates the adjustment of the heat fusion position and improves the installation flexibility, but also further improves the overall waterproof effect. Furthermore, by providing the snap-fit part 101 and the raised part 102, the elastic deformation capability of the unit roof panel 1 is improved, thereby improving the roof panel's resistance to thermal expansion and contraction.
[0042] Please see Figure 2 and Figure 3 The snap-fit part 101 has a U-shaped cross section, the raised part 102 has a trapezoidal or semi-circular cross section, and the horseshoe buckle 2 has a snap-fit cavity 203 for the snap-fit part 101 to be inserted into.
[0043] Specifically, the snap-fit portion 101 and the raised portion 102 undergo elastic deformation when subjected to external force or internal stress generated by thermal expansion and contraction, thereby further improving the wind resistance of the unit roof panel 1.
[0044] In this embodiment, the metal substrate 103 is made of aluminum-zinc plate, the thermoplastic plate 104 is made of thermoplastic polyolefin elastomer or polyvinyl chloride, and the horseshoe buckle 2 is made of aluminum alloy.
[0045] Specifically, the metal substrate 103 made of aluminum-zinc plate has high strength and toughness, which improves the wind resistance of the unit roof panel 1.
[0046] Please see Figure 3 and Figure 6 The horseshoe buckle 2 includes a fixing plate 201, which is fixedly connected to a pair of oppositely arranged side plates 202. A snap-fit cavity 203 is opened on the side plate 202. The fixing plate 201 abuts against the purlin 4 and has multiple screw holes for self-tapping screws 3 to pass through. An abutting plate 204 is fixedly connected to the side of the side plate 202 away from the fixing plate 201. The abutting plate 204 abuts against the horizontal part of the unit roof panel 1 located between the snap-fit part 101 and the raised part 102.
[0047] Specifically, by providing a snap-fit cavity 203 and an abutment plate 204, the horseshoe buckle 2 and the unit roof panel 1 have a larger contact area, which improves the stability of the roof panel fixing and the uniformity of the force.
[0048] Please see Figures 7-10 In the second embodiment of the present invention, based on the first embodiment, a high wind-resistant and leak-proof concealed roofing system is provided, wherein a concave portion 106 is formed by bending inward in the middle of the raised portion 102, and a pulling component 5 is engaged in the concave portion 106, and the lower end of the pulling component 5 is engaged in the horseshoe buckle 2.
[0049] Specifically, the horseshoe buckle 2 is connected to the concave portion 106 in the middle of the raised portion 102 of the adjacent unit roof panel 1 through the tensioning component 5. When the unit roof panel 1 is compressed, the tensioning component 5 provides support for the raised portion 102, improving the compressive strength of the raised portion 102. At the same time, when the unit roof panel 1 is subjected to outward pulling force under strong winds, the tensioning component 5 pulls the raised portion 102 inward, further improving the wind resistance of the unit roof panel 1. Meanwhile, by reducing the deformation of the raised portion 102, the probability of tearing of the welded strip 105 is reduced, improving the anti-leakage performance. It should be noted that the raised portion 102 is the raised part of the entire roof panel. When strong winds pass through the surface of the roof panel, the sidewall of the raised portion 102 is subjected to lateral force, tending to detach from the roof panel, and is subjected to an outward force away from the roof panel.
[0050] Please see Figure 8 , Figure 9 and Figure 10 The traction component 5 includes an upper clamp 6 that engages with the recessed portion 106. A sliding rod 7 is fixedly connected to the lower end of the upper clamp 6. The sliding rod 7 slides through a lower clamp 8. The lower end of the lower clamp 8 engages with a horseshoe buckle 2.
[0051] Specifically, when the raised portion 102 tends to move away from the roof panel, the horseshoe buckle 2 pulls the sliding rod 7 through the lower clamp 8, and the sliding rod 7 pulls the concave portion 106 through the upper clamp 6, thereby achieving the traction of the raised portion 102.
[0052] Please see Figure 8 and Figure 9 The concave part 106 has a U-shaped cross section. The upper clamp 6 has a semi-enclosed structure and is fitted on the outside of the concave part 106. The lower clamp 8 has a pair of locking posts 10 fixedly connected to its outer wall. The horseshoe buckle 2 has a pair of locking holes 205 that are inserted and matched with the locking posts 10.
[0053] Specifically, the upper clamp 6 and the inner recess 106 are fixed by the cooperation of the inner recess 106 and the upper clamp 6. The lower clamp 8 and the horseshoe buckle 2 are fixed by the cooperation of the clamping post 10 and the clamping hole 205. It should be noted that the clamping hole 205 is opened on the inner wall of the opposite side of the pair of side plates 202.
[0054] Please see Figure 9 and Figure 10 The sliding rod 7 is a round rod with an inverted T-shaped cross section. A spring 9 is sleeved on the sliding rod 7. The upper end of the spring 9 abuts against the lower end face of the upper clamp 6, and the lower end of the spring 9 abuts against the upper end face of the lower clamp 8. The cross section of the lower clamp 8 is an inverted lantern shape, and the cross section of the horseshoe buckle 2 is a trapezoid with the tip pointing upwards.
[0055] Specifically, the spring 9 provides a certain length adjustment range for the tensioning assembly 5, facilitating installation and providing cushioning when pulled, thus improving its compressive and tensile strength. Simultaneously, the semi-enclosed upper clamp 6 and the lower clamp 8 with an inverted lantern-shaped cross-section allow the tensioning assembly 5 a certain elastic deformation range, further enhancing its compressive and tensile strength. Furthermore, during installation, the horseshoe buckle 2 is installed first and located within the adjacent raised portion 102 (when installing the roof panel, the first unit roof panel 1 is first fixed with the horseshoe buckle 2 and self-tapping screws 3, then...). The raised portion 102 of another unit roof panel 1 is covered on the installed horseshoe buckle 2. Then, the protrusion of the thermoplastic plate 104 is heat-fused to fix the portion between the snap-fit portion 101 and the raised portion 102 of the adjacent unit roof panel 1. Therefore, by snapping the upper clamp 6 into the end of the recess 106 and sliding the traction assembly 5 along the recess 106, when encountering the first few horseshoe buckles 2 that need to be avoided, the lower clamp 8 is rotated. Since the lower clamp 8 is inverted lantern shape, the tip of the horseshoe buckle 2 passes through the lower end opening of the lower clamp 8, which facilitates the installation of multiple traction assemblies 5.
[0056] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
