Description

Technical Field

[0001] This application relates to the technical field of factory building roofs, and specifically relates to a light steel factory building with integrated roof lighting and insulation. Background Art

[0002] In the field of light steel factory buildings, the integrated design of roof lighting and insulation is an important means to improve the environmental comfort and energy-saving efficiency of factory buildings. In the prior art, to achieve the lighting function, skylights or lighting panels are usually installed on the roof. However, the core problem of such structures is the insufficient sealing between the roof frame and the roof body.

[0003] Sealing structure defect: Traditional sealing methods mostly use single-layer sealant or rubber pads. They are easily aged and cracked by ultraviolet rays and rainwater erosion when exposed to the external environment for a long time, resulting in frequent water seepage problems. For example, a steel structure factory building with a lighting structure with the publication number CN215802721U optimized the skylight structure but did not solve the problem of weak sealing at the connection between the frame and the roof.

[0004] Hidden danger of water accumulation and corrosion: Most existing roof frames are designed horizontally or slightly inclined, and rainwater is likely to stagnate at the sealing place to form water accumulation, accelerating the corrosion of the sealing material, especially in high-humidity or acid-rain environments.

[0005] Therefore, the present invention proposes a light steel factory building with integrated roof lighting and insulation. Summary of the Invention

[0006] The purpose of this application is: to solve the problems in the above background art, this application provides a light steel factory building with integrated roof lighting and insulation.

[0007] To achieve the above purpose, this application specifically adopts the following technical solutions: A light steel factory building with integrated roof lighting and insulation, comprising: A roof panel, on which a plurality of light-transmitting grooves are opened, and a waterproof layer is provided on the outer plate surface of the roof panel; A frame structure, including a sealing layer. The sealing layer is in a circular shape and is laid around the light-transmitting grooves on the waterproof layer. A frame-shaped plate is installed on the roof panel and presses on the sealing layer; An inner sealing layer, which is arranged on the inner plate surface of the roof panel. The inner sealing layer presses on the edge of the light-transmitting groove. The edge of the inner sealing layer is located inside the light-transmitting groove and is provided with a circular raised pad. A circular groove is formed between the circular raised pad and the light-transmitting groove; A support frame, which is installed on the inner plate surface of the roof panel and presses on the inner sealing layer. The inner edge along the support frame is aligned with the inner edge of the circular raised pad; A guiding member, which is arranged in the circular groove. A drainage groove is provided on the roof panel. The guiding member is communicated with the drainage groove, and the liquid is drained into the drainage groove through the guiding member.

[0008] Further, the guiding member includes a rectangular frame plate pressed in the rectangular groove. Two liquid discharge grooves are symmetrically formed in the rectangular frame plate along the inclination direction of the roof panel. A rectangular retaining pad is formed along the inner edge of the rectangular gasket, and the bottom of the rectangular retaining pad is pressed on the rectangular frame plate.

[0009] Further, a plurality of convex blocks are arrayed along the inclination direction on the side of the liquid discharge groove away from the rectangular retaining pad. An upper pressing plate is further included. A plurality of slots are formed in the upper pressing plate. The upper pressing plate is installed on the inclined surface of the rectangular frame plate through the cooperation of the slots and the convex blocks, so that the upper pressing plate and the rectangular frame plate press on the upper and lower end faces of the rectangular retaining pad.

[0010] Further, the side of the rectangular frame plate away from the liquid discharge groove is inclined along the direction of the liquid discharge groove, and the convex blocks are formed on the inclined surface of the rectangular frame plate.

[0011] Further, a collecting groove is formed between the lowest end of the upper surface of the rectangular frame plate and the light-transmitting groove. The drainage groove is formed through the wall thickness of the roof panel, and the highest end of the drainage groove is communicated with the collecting groove.

[0012] Further, the sealing layer covers the upper surface of the rectangular frame plate, and the frame-shaped plate is installed on the roof panel through bolts.

[0013] Further, the support frame includes two right-angle insertion cylinders and right-angle insertion rods. The two right-angle insertion cylinders are diagonally distributed and the two ends are respectively slidably matched with one end of the two right-angle insertion rods to form a rectangular closed area. Connecting convex plates are formed at the corners of the right-angle insertion rods and the right-angle insertion cylinders, and through holes are formed in the connecting convex plates.

[0014] Further, one side in the length direction of the right-angle insertion cylinder is open, and one side in the length direction of the right-angle insertion rod is flush with the open end of the right-angle insertion cylinder.

[0015] Further, a partition plate connected to the steel structure support assembly of the factory building is further included. The partition plate is located below the roof panel, and a heat insulation layer is provided on the upper surface of the partition plate. The heat insulation layer is located between the roof panel and the partition plate.

[0016] Further, the heat insulation layer is made of glass wool material, and the partition plate is made of mineral wool material.

[0017] The beneficial effects of the present application are as follows: Through the design of the inner sealing layer and the return-shaped convex pads, this application can effectively prevent rainwater from flowing into the factory building from the support frame. With the cooperation of the guiding members, the infiltrated water generally evaporates after flowing in the guiding members for a period of time. When the amount of infiltrated rainwater is large, the guiding members will also guide the rainwater into the drainage grooves and finally discharge it to the outside. Since the inner sealing layer is located inside the factory building and the return-shaped convex pads rarely come into contact with rainwater, it is difficult to accelerate aging due to the erosion of rainwater. This not only effectively improves the rainwater anti-seepage effect but also has a long service life and reduces the corrosion rate of the sealing material. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0020] As Figures 1 - 13 shown, a light steel workshop for integrated roof lighting and thermal insulation proposed in an embodiment of the present application includes: A roof panel 1, the roof panel 1 can be an existing color steel plate. However, compared with the existing color steel plate, the thickness of the roof panel 1 of this device is about four times that of the existing color steel plate, and the outer surface is designed with straight wave grooves. The roof panels 1 are connected by connectors. A plurality of light-transmitting grooves 3 are provided on the roof panel 1. A waterproof layer 2 is provided on the outer plate surface of the roof panel 1. The waterproof layer 2 is a 1.5 PVC waterproof coiled material and is laid on the upper plate surface of the roof panel 1 by a full-adhesion process; A frame structure, including a sealing layer 4. The sealing layer 4 is in a return shape and is laid around the light-transmitting groove 3 on the waterproof layer 2. The sealing layer 4 is a 1.5 PVC waterproof coiled material and is also laid on the waterproof layer 2 by a full-adhesion process. A frame-shaped plate 5 is installed on the roof panel 1 and presses on the sealing layer 4. In this embodiment, after the laying of the sealing layer 4 is completed, the frame-shaped plate 5 is installed on the roof panel 1 by bolts to press and seal the sealing layer 4. The double sealing of the sealing layer 4 and the waterproof layer 2 effectively prevents rainwater from seeping in from between the frame-shaped plate 5 and the roof panel 1 on rainy days; An inner sealing layer 7 is provided on the inner plate surface of the roof panel 1. That is to say, the inner sealing layer 7 is provided on the side of the roof panel 1 close to the inside of the workshop. The inner sealing layer 7 presses on the edge of the light-transmitting groove 3. A return-shaped convex pad 8 is formed at the edge of the inner sealing layer 7 and is located inside the light-transmitting groove 3. That is to say, the return-shaped convex pad 8 is located inside the light-transmitting groove 3 and close to its edge, so that a return-shaped groove 9 is formed between the return-shaped convex pad 8 and the groove wall of the light-transmitting groove 3; The support frame 6 is installed on the inner surface of the roof panel 1 and presses the inner sealing layer 7. In this embodiment, the support frame 6 can be installed on the inner surface of the roof panel 1 by bolts, so as to indirectly install the inner sealing layer 7 on the inner surface of the roof panel 1. The inner edge of the support frame 6 is aligned with the inner edge of the loop gasket 8. That is to say, after the support frame 6 is installed, the inner sealing layer 7 is located between the support frame 6 and the inner surface of the roof panel 1. The guide member 10 is arranged in the loop-shaped groove 9. That is to say, the guide member 10 is loop-shaped and covers the loop-shaped groove 9. The roof panel 1 is provided with a drainage groove 11, and the guide member 10 is communicated with the drainage groove 11. The liquid is drained into the drainage groove 11 through the guide member 10. After the guide member 10 is arranged in the loop-shaped groove 9, the frame-shaped plate 5 is installed on the roof panel 1, so that the roof panel 1 presses on the guide member 10, so that the guide member 10 and the support frame 6 press the inner sealing layer 7, thereby further improving the sealing performance. After the rainwater falls on the support frame 6, rainwater will accumulate at the end face of the frame-shaped plate 5A. Because the frame-shaped plate 5 is inclined, the rainwater on the end face of the frame-shaped plate 5A will flow out in the direction of the side adjacent to the A end face due to the action of gravity. Therefore, the end face of the frame-shaped plate 5A has the longest rainwater retention time on rainy days. Therefore, the waterproof layer 2 near the A end face is most easily eroded by rainwater. Coupled with the long-term influence of ultraviolet rays, it is easy to age and crack. And in the sealing layer 4, because it is pressed by the frame-shaped plate 5, rainwater and ultraviolet rays are not easy to erode the sealing layer 4. Because the rainwater retention time on the end face of the frame-shaped plate 5A is the longest, after long-term use, the sealing layer 4 near the A end face is the first to age compared with other positions. However, due to the design of the inner sealing layer 7 and the guide member 10, when part of the rainwater seeps into the light-transmitting groove 3 from the end face of the frame plate A, at this time, due to the design of the inner sealing layer 7 and the loop gasket 8, it can effectively prevent the rainwater from flowing from the support frame 6 into the factory building. With the cooperation of the guide member 10, the infiltrated water generally evaporates after flowing in the guide member 10 for a period of time. When the amount of infiltrated rainwater is large, the guide member 10 will also guide the rainwater into the drainage groove 11 and finally be discharged to the outside. And because the inner sealing layer 7 is located inside the factory building and the loop gasket 8 rarely contacts rainwater, it is difficult to accelerate aging due to rainwater erosion. Preferably, the inner sealing layer 7 and the loop gasket 8 are made of rubber material, which has a good sealing effect, and the sealing effect will be further improved under the pressure of the support frame 6 and the frame-shaped plate 5. This not only effectively improves the rainwater anti-seepage effect, but also has a long service life, reduces the corrosion rate of the sealing material. In this embodiment, the skylight is installed on the frame-shaped plate 5.

[0021] Such as Figure 9 、 Figure 10 And Figure 13As shown, in some embodiments, the guide member 10 includes a rectangular frame plate 1001 pressed in the rectangular groove 9. Two drain grooves 1002 are symmetrically formed along the inclination direction of the roof panel 1 of the rectangular frame plate 1001. A rectangular retaining pad 1003 is constructed along the inner edge of the rectangular cushion 8. The bottom of the rectangular retaining pad 1003 is pressed on the rectangular frame plate 1001. That is to say, the bottom of the rectangular retaining pad 1003 is tightly pressed on the rectangular frame plate 1001. When rainwater penetrates through the frame plate 5 from the A end of the frame plate 5, the rainwater will flow into one end face of the rectangular cushion 8 close to the A end, and then the rainwater will flow to both sides and finally flow into the two drain grooves 1002. When the rainwater flows to the lowest end of the drain groove 1002, it flows into the drainage groove 11 and then flows to the outside. In this embodiment, after the frame plate 5 is installed on the roof panel 1, it is pressed on the rectangular retaining pad 1003, thereby forming a seal to prevent the rainwater penetrating into the light-transmitting groove 3 from flowing through the rectangular retaining pad 1003 and entering the factory building.

[0022] As Figures 2 - 3 As shown, in some embodiments, a plurality of convex blocks 12 are arrayed along the inclination direction on the side of the drain groove 1002 away from the rectangular retaining pad 1003. It further includes an upper pressing plate 13. A plurality of slots 14 are formed on the upper pressing plate 13. The upper pressing plate 13 is installed on the inclined surface of the rectangular frame plate 1001 by matching the slots 14 with the convex blocks 12, so that the upper pressing plate 13 and the rectangular frame plate 1001 press on the upper and lower end faces of the rectangular retaining pad 1003. That is to say, after the upper pressing plate 13 is installed on the rectangular frame plate 1001, the rectangular retaining pad 1003 is located between the upper pressing plate 13 and the rectangular frame plate 1001. In this embodiment, the sealing layer 4 covers the upper surface of the rectangular frame plate 1001. The frame plate 5 is installed on the roof panel 1 by bolts. That is to say, the inner edge of the sealing layer 4 is aligned with the inner edge plate of the upper pressing plate 13. The skylight is directly pressed on the upper pressing plate 13 and presses the inner edge of the sealing layer 4. The skylight pressed on the upper pressing plate 13 is flush with the frame plate 5. The frame plate 5 and the skylight are installed through a sealing adhesive, thereby completing the installation of the skylight. At this time, the rectangular retaining pad 1003 is also located below the sealing layer 4, playing a role in shading and preventing the rectangular retaining pad 1003 from being eroded by ultraviolet rays.

[0023] As Figure 11 As shown, in some embodiments, on the side of the rectangular frame plate 1001 away from the drain groove 1002, it is inclined along the direction of the drain groove 1002. The convex blocks 12 are constructed on the inclined surface of the rectangular frame plate 1001. As shown in the figure, when water seeps out from the two sides of the frame plate 5 adjacent to the A end, the inclined structure of the drain groove 1002 can effectively guide the rainwater into the drain groove 1002, further improving the collection effect of rainwater seepage.

[0024] As Figure 10As shown, in some embodiments, a collecting groove 15 is formed between the lowest end of the upper surface of the U-shaped frame plate 1001 and the light-transmitting groove 3. The drainage groove 11 is formed through the wall thickness of the roof panel 1, and the highest end of the drainage groove 11 communicates with the collecting groove 15. When rainwater flows along the drainage groove 1002 to the lowest end, the rainwater will enter the collecting groove 15. The diameter of the collecting groove 15 is larger than that of the drainage groove 11, which can well guide the rainwater into the drainage groove 11, so that the rainwater flows into the drainage groove 11 under the action of gravity and is discharged to the outside.

[0025] As Figure 6 and Figure 9 shown, in some embodiments, the support frame 6 includes two right-angle insertion cylinders 601 and right-angle insertion rods 602. The two right-angle insertion cylinders 601 are diagonally distributed and the two ends are respectively in sliding fit with one end of the two right-angle insertion rods 602 to form a U-shaped closed area. Connecting convex plates 603 are constructed at the corners of the right-angle insertion rods 602 and the right-angle insertion cylinders 601, and through holes 604 are formed in the connecting convex plates 603. That is to say, the connecting convex plates 603 can be installed on the inner plate surface of the roof panel 1 by bolts, and the design of the right-angle insertion rods 602 and the right-angle insertion cylinders 601 can adjust the size of the U-shaped closed area of the support frame 6 according to the size of the light-transmitting groove 3, improving the applicability.

[0026] As Figure 6 and Figure 9 shown, in some embodiments, one side in the length direction of the right-angle insertion cylinder 601 is open, and one side in the length direction of the right-angle insertion rod 602 is flush with the open end of the right-angle insertion cylinder 601. That is to say, the open end of the right-angle insertion cylinder 601 is in direct contact with the inner sealing layer 7 of the right-angle insertion rod 602. The design of the open end of the right-angle insertion cylinder 601 increases the force-bearing area with the inner sealing layer 7, further improving the sealing effect.

[0027] As Figure 9 shown, in some embodiments, it further includes a partition plate 16 connected to the steel structure support assembly of the factory building. In this embodiment, the partition plate 16 can be installed on the roof beam. The partition plate 16 is located below the roof panel 1, and a heat-insulating layer 17 is provided on the upper surface of the partition plate 16. The heat-insulating layer 17 is located between the roof panel 1 and the partition plate 16. The design of the heat-insulating layer 17 improves the heat-insulating effect in the factory building.

[0028] As Figure 9 shown, in some embodiments, the heat-insulating layer 17 is made of glass wool material, and the partition plate 16 is made of mineral wool material. The glass wool material has good high-temperature resistance, while the partition plate 16 made of mineral wool material has good sound insulation effect, thereby reducing the noise in the factory building.

[0029] The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
