Description

Technical Field

[0001] This invention relates to the field of building roof components technology, and in particular to a waterproof installation structure for a skylight panel. Background Technology

[0002] In metal roofing systems for industrial or civil buildings, skylights are often used in conjunction with coated metal roofing panels to meet indoor lighting requirements. Currently, the widely adopted installation method in the industry is as follows: first, supports are fixed to the roof purlins; then, self-tapping screws are used to directly penetrate the protruding edges of the skylight and secure it to the supports. Simultaneously, at the lateral overlap between the skylight and the metal roofing panel, a waterproof sealing strip is installed and used in conjunction with self-tapping screws for a secure connection.

[0003] Skylight panels (such as FRP and PC) have different material properties than metals, typically being more brittle and lacking in toughness. When self-tapping screws are directly tightened onto the stress-concentrated ridges of the skylight panel, micro-cracks or even full cracks can easily form around the fastening points due to installation stress, structural deformation during use, wind loads, and temperature changes. These cracks turn the fastening points into potential leak points, affecting the reliability of the roof's waterproofing and posing a long-term risk of leakage.

[0004] Therefore, the existing waterproof installation structure for skylights has the problem of low waterproof reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof installation structure for skylights, aiming to solve the problem of low waterproof reliability in existing waterproof installation structures for skylights.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: providing a waterproof installation structure for a light-transmitting panel, the light-transmitting panel waterproof installation structure including a light-transmitting panel and purlin hangers, the light-transmitting panel being fixedly installed on the upper surface of the purlin through the purlin hangers; The light-transmitting panel is provided with a raised ridge, and an inner hanging groove is provided on both sides of the raised ridge; The purlin hanger includes a strip-shaped pressure plate, a tie post, and a locking assembly. The two ends of the strip-shaped pressure plate are respectively engaged in the inner hanging groove of the skylight panel. One end of the tie post passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate. The other end of the tie post is threadedly connected to the locking assembly. The locking assembly abuts against the lower surface of the purlin to press the skylight panel onto the purlin.

[0007] Furthermore, the long axis of the inner hanging groove is parallel to the long axis of the protruding ridge.

[0008] Furthermore, the locking assembly includes an external threaded sleeve and a locking nut. The external threaded sleeve is sleeved on the outside of the tie column, and the locking nut is threadedly connected to the external threaded sleeve. The upper end of the locking nut abuts against the lower surface of the purlin, and the light-transmitting panel is pressed onto the purlin by tightening the locking nut.

[0009] Furthermore, the end of the pull column that is not connected to the strip pressure plate is provided with a hexagonal head.

[0010] Furthermore, a limiting platform is provided at the end of the pull column that is not connected to the strip pressure plate, and the diameter of the limiting platform is larger than the inner diameter of the external threaded sleeve.

[0011] Furthermore, a washer is provided between the strip-shaped pressure plate and the locking nut, and the washer is sleeved on the outside of the external threaded sleeve.

[0012] Furthermore, the snap-fit ​​surface of the strip-shaped pressure plate that contacts the inner hanging groove is provided with anti-slip ridges.

[0013] Furthermore, the strip-shaped pressure plate is provided with a threaded sleeve, and the pull column is provided with a connecting thread, which is threadedly connected to the threaded sleeve.

[0014] Furthermore, the threaded sleeve is located at the center of the strip-shaped pressure plate and extends towards the purlin.

[0015] Furthermore, the strip-shaped pressure plate is made of high-carbon steel.

[0016] This invention discloses a waterproof installation structure for a skylight panel. The structure includes a skylight panel and purlin hangers. The skylight panel is fixedly mounted on the upper surface of the purlin via the purlin hangers. The skylight panel has a raised ridge, and inner hanging grooves are respectively provided on both sides of the raised ridge. The purlin hangers include a strip-shaped pressure plate, a pull post, and a locking assembly. Both ends of the strip-shaped pressure plate are respectively engaged in the inner hanging grooves of the skylight panel. One end of the pull post passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate. The other end of the pull post is threadedly connected to the locking assembly. The locking assembly abuts against the lower surface of the purlin to press the skylight panel firmly onto the purlin. This invention adopts a non-penetrating installation structure, which uses an internal hanging groove and a strip pressure plate to engage with each other. It eliminates the need to drill holes and nails in the skylight, fundamentally avoiding stress concentration, micro-cracks and cracking problems caused by traditional self-tapping screw installation, completely eliminating the risk of water leakage at the fastening point, and improving the waterproof reliability and durability of the roof system.

[0024] Please see Figure 1 and Figure 5 This invention proposes a waterproof installation structure for a skylight panel, comprising a skylight panel 2 and a purlin hanger 4. The skylight panel 2 is fixedly mounted on the upper surface of a purlin 1 via the purlin hanger 4. The skylight panel 2 has a raised ridge, and inner hanging grooves 3 are respectively provided on both sides of the raised ridge. The purlin hanger 4 includes a strip-shaped pressure plate 5, a pull post 6, and a locking assembly. Both ends of the strip-shaped pressure plate 5 are respectively engaged in the inner hanging grooves 3 of the skylight panel 2. One end of the pull post 6 passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate 5. The other end of the pull post 6 is threadedly connected to the locking assembly. The locking assembly abuts against the lower surface of the purlin 1 to press the skylight panel 2 onto the purlin 1.

[0025] In this embodiment, inner hanging grooves 3 are respectively provided on both sides of the protruding ridge. The inner hanging grooves 3 are integrally formed by molding and other processes during the manufacturing of the light-transmitting panel 2, and are part of the structure of the light-transmitting panel 2 itself. The purlin hanger 4 is a force-bearing and connecting component, and the light-transmitting panel 2 is fixedly mounted on the upper surface of the purlin 1 through the purlin hanger 4. Due to the limited operating space below the light-transmitting panel 2, it is very difficult to directly move the strip pressure plate 5 laterally to make it fit into the inner hanging groove 3. During installation, the strip pressure plate 5 is not directly aligned with the inner hanging groove 3. Instead of placing the purlin 6 in the inner hanging groove 3, the purlin 6 is positioned with its length direction parallel to the direction of the inner hanging groove 3, and is placed inside the convex ridge. Then, one end of the pull post 6 passes through the pre-set purlin mounting hole on the purlin 1 and is threadedly connected to the strip pressure plate 5. After that, by rotating the pull post 6, the strip pressure plate 5 is driven to rotate inside the convex ridge, so that both ends of the strip pressure plate 5 are respectively engaged in the inner hanging groove 3 of the light-transmitting panel 2. Finally, the locking assembly is tightened to press the strip pressure plate 5, so that the light-transmitting panel 2 is pressed tightly onto the purlin 1.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, the long axis of the inner hanging groove 3 is parallel to the long axis of the protruding ridge.

[0027] In this embodiment, the long axis of the inner hanging groove 3 is parallel to the long axis of the protruding ridge to improve the stability of the connection between the strip pressure plate 5 and the inner hanging groove 3. During installation, the strip pressure plate 5 is not directly aligned with the inner hanging groove 3, but is placed inside the protruding ridge with its length direction parallel to the direction of the protruding ridge and the inner hanging groove 3.

[0028] In one embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly includes an external threaded sleeve 7 and a locking nut 8. The external threaded sleeve 7 is sleeved on the outside of the tie column 6, and the locking nut 8 is threadedly connected to the external threaded sleeve 7. The upper end of the locking nut 8 abuts against the lower surface of the purlin 1. By tightening the locking nut 8, the light-transmitting panel 2 is pressed against the purlin 1.

[0029] In this embodiment, during installation, the strip-shaped pressure plate 5 is placed inside the convex ridge with its length direction parallel to the direction of the inner hanging groove 3. The external threaded sleeve 7 is sleeved on the outside of the pull post 6. One end of the pull post 6 passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate 5. Then, by rotating the pull post 6, the strip-shaped pressure plate 5 is driven to rotate inside the convex ridge, so that both ends of the strip-shaped pressure plate 5 are respectively engaged in the inner hanging groove 3 of the light-transmitting panel 2. Finally, the locking nut 8 is tightened to press the strip-shaped pressure plate 5, so that the light-transmitting panel 2 is pressed against the purlin 1.

[0030] In one embodiment, such as Figure 3 and Figure 4 As shown, the end of the pull post 6 that is not connected to the strip pressure plate 5 is provided with a hexagonal head 11.

[0031] In this embodiment, during installation, the strip-shaped pressure plate 5 is placed inside the convex ridge with its length direction parallel to the direction of the inner hanging groove 3. The external threaded sleeve 7 is sleeved on the outside of the pull post 6. One end of the pull post 6 passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate 5. Then, a wrench is used to hold the hexagonal head 11, and by rotating the pull post 6, the strip-shaped pressure plate 5 is driven to rotate inside the convex ridge, so that both ends of the strip-shaped pressure plate 5 are respectively engaged in the inner hanging groove 3 of the light-transmitting panel 2. Finally, the locking assembly is tightened to press the strip-shaped pressure plate 5, so that the light-transmitting panel 2 is pressed against the purlin 1.

[0032] In one embodiment, such as Figure 3 and Figure 4 As shown, a limiting platform 10 is provided at the end of the pull column 6 that is not connected to the strip pressure plate 5, and the diameter of the limiting platform 10 is larger than the inner diameter of the external threaded sleeve 7.

[0033] In this embodiment, a limiting platform 10 is provided at the end of the pull post 6 that is not connected to the strip pressure plate 5. The diameter of the limiting platform 10 is larger than the inner diameter of the external threaded sleeve 7. When the external threaded sleeve 7 is sleeved on the outside of the pull post 6, its lower end will be supported by the limiting platform 10, ensuring that the external threaded sleeve 7 will not move upward during the tightening of the locking nut 8, but will stably transmit the locking force to the pull post 6 through the limiting platform 10, thereby tightening the strip pressure plate and pressing the light-transmitting panel 2 onto the purlin 1.

[0034] In one embodiment, such as Figure 3 and Figure 4 As shown, a washer 9 is provided between the strip-shaped pressure plate 5 and the locking nut 8, and the washer 9 is sleeved on the outside of the external threaded sleeve 7.

[0035] In this embodiment, a washer 9 is provided between the strip-shaped pressure plate 5 and the locking nut 8. The washer 9 is sleeved on the outside of the external threaded sleeve 7. The washer 9 is used to increase the contact area between the locking nut 8 and the lower surface of the purlin 1, so that the pressure distribution is more uniform and the reliability of the connection is improved.

[0036] In one embodiment, such as Figure 3 and Figure 5 As shown, the snap-fit ​​surface of the strip-shaped pressure plate 5 that contacts the inner hanging groove 3 is provided with anti-slip ridges 14.

[0037] In this embodiment, the snap-fit ​​surface of the strip-shaped pressure plate 5 that contacts the inner hanging groove 3 is provided with anti-slip ridges 14. When both ends of the strip-shaped pressure plate 5 are snapped into the inner hanging groove 3 of the light-transmitting panel 2, these anti-slip ridges 14 can effectively increase the friction between the strip-shaped pressure plate 5 and the inner hanging groove 3, prevent the strip-shaped pressure plate 5 from sliding or shifting in the inner hanging groove 3, and further enhance the stability of the connection between the strip-shaped pressure plate 5 and the inner hanging groove 3.

[0038] In one embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the strip-shaped pressure plate 5 is provided with a threaded sleeve 13, and the pull column 6 is provided with a connecting thread 12, which is threadedly connected to the threaded sleeve 13.

[0039] In this embodiment, during installation, the strip-shaped pressure plate 5 is placed inside the convex ridge with its length direction parallel to the direction of the inner hanging groove 3. Then, one end of the pull post 6 passes through the purlin mounting hole and is threadedly connected to the threaded sleeve 13 on the strip-shaped pressure plate 5 through the connecting thread 12. After that, by rotating the pull post 6, the strip-shaped pressure plate 5 is driven to rotate inside the convex ridge, so that both ends of the strip-shaped pressure plate 5 are respectively engaged in the inner hanging groove 3 of the light-transmitting panel 2. Finally, the locking assembly is tightened to press the strip-shaped pressure plate 5, so that the light-transmitting panel 2 is pressed against the purlin 1.

[0040] In one embodiment, such as Figure 2 and Figure 5 As shown, the threaded sleeve 13 is located at the center of the strip-shaped pressure plate 5 and extends toward the purlin 1.

[0041] In this embodiment, the threaded sleeve 13 is located at the center of the strip-shaped pressure plate 5 and extends towards the purlin 1 to achieve coaxial connection with the tie column 6, thereby avoiding uneven force and skewing during installation.

[0042] In one embodiment, such as Figure 5 As shown, the strip-shaped pressure plate 5 is made of high carbon steel.

[0043] In this embodiment, the strip pressure plate 5 is made of high carbon steel, which has high hardness and fatigue strength, and is suitable for the complex stress conditions of the roof, avoiding deformation, loosening or even damage under long-term wind or snow pressure.

[0044] This invention discloses a waterproof installation structure for a skylight panel. The structure includes a skylight panel and purlin hangers. The skylight panel is fixedly mounted on the upper surface of the purlin via the purlin hangers. The skylight panel has a raised ridge, and inner hanging grooves are respectively provided on both sides of the raised ridge. The purlin hangers include a strip-shaped pressure plate, a pull post, and a locking assembly. Both ends of the strip-shaped pressure plate are respectively engaged in the inner hanging grooves of the skylight panel. One end of the pull post passes through the purlin mounting hole and is threadedly connected to the strip-shaped pressure plate. The other end of the pull post is threadedly connected to the locking assembly. The locking assembly abuts against the lower surface of the purlin to press the skylight panel firmly onto the purlin. This invention adopts a non-penetrating installation structure, which uses an internal hanging groove and a strip pressure plate to engage with each other.
