Abstract

The present application discloses a rooftop lighting and heat-insulating integrated light steel factory building, which relates to the technical field of factory roofs. The present application includes: a roof panel, wherein a plurality of light-transmitting grooves are provided on the roof panel, and a waterproof layer is provided on the outer surface of the roof panel; a frame structure, including a sealing layer, wherein the sealing layer is in a circular shape and is laid on the waterproof layer around the light-transmitting grooves. The present application can effectively prevent rainwater from flowing from the supporting frame into the factory building through the design of the inner sealing layer and the circular convex pad. With the cooperation of the guide, the infiltrated water will generally evaporate after flowing in the guide for a period of time. When the amount of infiltrated rainwater is large, the guide will also guide the rainwater into the drainage trough and finally be discharged to the outside. Because the inner sealing layer is located in the factory building and the circular convex pad rarely comes into contact with rainwater, it is difficult to accelerate aging due to the erosion of rainwater. This not only effectively improves the effect of preventing rainwater from penetrating, but also has a long service life and reduces the corrosion rate of the sealing material.

Description

Technical Field

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

[0002] In the field of lightweight steel factories, integrated roof lighting and insulation design is an important means to improve factory environmental comfort and energy efficiency. Existing technologies typically install skylights or skylight panels on the roof to achieve this lighting function. However, the core problem of such structures is the insufficient sealing between the roof frame and the roof body.

[0003] Sealing defects: Traditional sealing methods often use single-layer sealants or rubber pads, which are susceptible to UV rays and rainwater erosion, leading to aging and cracking, and frequent water seepage. For example, Publication No. CN215802721U describes a steel-structured factory building with a skylight structure. While the skylight structure was optimized, it failed to address the weak seal at the connection between the frame and the roof.

[0004] Hidden danger of corrosion due to accumulated water: Existing roof frames are mostly designed to be horizontal or slightly inclined. Rainwater can easily accumulate in the sealing area and form accumulated water, which accelerates the corrosion of the sealing material, especially in high humidity or acid rain environments.

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

The upper pressure plate is installed on the inclined surface of the return-shaped frame plate through the slots and the protrusions to form the upper pressure plate and the return-shaped frame plate pressed on the upper and lower end surfaces of the return-shaped baffle.

[0016] Furthermore, the side of the circular frame away from the drainage groove is in an inclined structure along the direction of the drainage groove, and the protrusion is constructed on the inclined structural surface of the circular frame.

[0017] Furthermore, a collecting groove is formed between the lowest end of the upper surface of the circular frame plate and the light-transmitting groove, the drainage groove is opened through the thickness of the roof panel wall, and the highest end of the drainage groove is connected to the collecting groove.

[0039] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present application.

[0040] like Figures 1-13 As shown, an embodiment of the present application proposes a light steel factory building with integrated roof lighting and insulation, comprising:

[0041] Roof panel 1, roof panel 1 can be an existing color steel plate, but compared with the existing color steel plate, the thickness of the roof panel 1 of the device is about four times that of the existing color steel plate, the outer surface is designed with linear wave grooves, the roof panels 1 are connected with connecting parts, a plurality of light-transmitting grooves 3 are opened on the roof panel 1, and the outer surface of the roof panel 1 is provided with a waterproof layer 2, which is a 1.5PVC waterproof membrane, and is laid on the upper surface of the roof panel 1 using a full-bonding process;

[0042] The frame structure includes a sealing layer 4. The sealing layer 4 is in a circular shape and is laid on the waterproof layer 2 around the light-transmitting groove 3. The sealing layer 4 is a 1.5 PVC waterproof membrane and is also laid on the waterproof layer 2 using a full-bonding process. The roof panel 1 is installed with a frame plate 5 that is pressed against the sealing layer 4. In this embodiment, after the sealing layer 4 is laid, the frame plate 5 is installed on the roof panel 1 by bolts to press and seal the sealing layer 4. The double seal between the sealing layer 4 and the waterproof layer 2 effectively prevents rainwater from seeping in between the frame plate 5 and the roof panel 1 during rainy days.

[0043] An inner sealing layer 7 is provided on the inner surface of the roof panel 1, that is, the inner sealing layer 7 is provided on the side of the roof panel 1 close to the factory building. The inner sealing layer 7 presses the edge of the light-transmitting groove 3. The edge of the inner sealing layer 7 is located in the light-transmitting groove 3 and is configured with a return-shaped convex pad 8. That is, the return-shaped convex pad 8 is located in 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;

[0044] 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, thereby indirectly installing 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 return convex pad 8. That is, 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;

[0045] The guide member 10 is arranged in the return groove 9, that is, the guide member 10 is return-shaped and covers the return groove 9. The roof panel 1 is provided with a drainage groove 11, and the guide member 10 is connected to the drainage groove 11. The liquid is drained into the drainage groove 11 through the guide member 10. When the guide member 10 is arranged in the return groove 9, the frame plate 5 is installed on the roof panel 1, so that the roof panel 1 is pressed 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, and rainwater falling into the support frame 6 is not easily damaged. After the support frame 6 is installed, rainwater will accumulate at the end face of the frame plate 5A. Because the frame plate 5 is tilted, the rainwater on the end face of the frame plate 5A will flow out from the side adjacent to the A end face due to gravity. Therefore, the end face of the frame plate 5A retains rainwater for the longest time on rainy days. Therefore, the waterproof layer 2 close to the A end face is most susceptible to rainwater erosion, and is prone to aging and cracking due to long-term exposure to ultraviolet rays. However, the sealing layer 4 is pressed by the frame plate 5, so rainwater and ultraviolet rays are not easy to erode the sealing layer 4. The rainwater on the A end face stays for the longest time, so after long-term use, the sealing layer 4 near the A end face is easy to age first compared with other positions. However, due to the design of the inner sealing layer 7 and the guide 10, when some rainwater penetrates from the A end face of the frame plate into the light-transmitting groove 3, the design of the inner sealing layer 7 and the return convex pad 8 can effectively prevent the rainwater from flowing from the support frame 6 into the factory building. With the cooperation of the guide 10, the infiltrated water will generally evaporate after flowing in the guide 10 for a period of time. When the amount of infiltrated rainwater is large, it will pass through the guide 10. 0 will also guide the rainwater into the drainage trough 11 and finally be discharged to the outside. Because the inner sealing layer 7 is located in the factory building and the return-shaped convex pad 8 rarely comes into contact with rainwater, it is difficult to accelerate aging due to the erosion of rainwater. Preferably, the inner sealing layer 7 and the return-shaped convex pad 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 supporting frame 6 and the frame plate 5. This not only effectively improves the effect of preventing rainwater from penetrating, but also has a long service life and reduces the corrosion rate of the sealing material. In this embodiment, the skylight is installed on the frame plate 5.

[0046] like Figure 9 、 Figure 10 and Figure 13As shown, in some embodiments, the guide 10 includes a return frame plate 1001 pressed in the return groove 9, and the return frame plate 1001 has two drainage grooves 1002 symmetrically opened along the tilt direction of the roof panel 1, and a return stopper 1003 is constructed along the edge of the return convex pad 8. The bottom of the return stopper 1003 is pressed on the return frame plate 1001, that is, the bottom of the return stopper 1003 is tightly pressed on the return frame plate 1001. When rainwater flows from the frame plate 5A When the rainwater penetrates through the frame plate 5, it will flow into the end face of the return convex pad 8 close to the A end, and then the rainwater will flow to both sides, and finally flow into the two drainage grooves 1002. When the rainwater flows into the lowest end of the drainage groove 1002, it will flow into the drainage groove 11, and then flow into the outside. In this embodiment, after the frame plate 5 is installed on the roof panel 1, it will be pressed on the return baffle 1003, thereby forming a seal to prevent rainwater that has penetrated into the light-transmitting groove 3 from flowing through the return baffle 1003 and entering the factory building.

[0047] like Figure 2-Figure 3 As shown, in some embodiments, the drainage trough 1002 is configured with a plurality of protrusions 12 in an array along its inclined direction on one side away from the return-shaped baffle 1003, and further includes an upper pressure plate 13, on which a plurality of slots 14 are provided. The upper pressure plate 13 is mounted on the inclined surface of the return-shaped frame plate 1001 through the slots 14 in cooperation with the protrusions 12, so as to form the upper pressure plate 13 and the return-shaped frame plate 1001 pressed against the upper and lower end surfaces of the return-shaped baffle 1003, that is, the upper pressure plate 13 is installed behind the return-shaped frame plate 1001, and the return-shaped baffle 1003 is located between the upper pressure plate 13 and the return-shaped frame plate 1001 In this embodiment, the sealing layer 4 covers the upper surface of the circular frame plate 1001, and the frame plate 5 is installed on the roof panel 1 by bolts, that is, the inner edge of the sealing layer 4 is aligned with the inner edge of the upper pressure plate 13, the skylight is directly pressed on the upper pressure plate 13, and the inner edge of the sealing layer 4 is pressed. The skylight pressed on the upper pressure plate 13 is flush with the frame plate 5, and the frame plate 5 and the skylight are installed by sealant, thereby completing the installation of the skylight. At this time, the circular baffle 1003 is also located below the sealing layer 4, which plays a sunshade role and prevents the circular baffle 1003 from being eroded by ultraviolet rays.

[0048] like Figure 11 As shown, in some embodiments, the side of the circular frame plate 1001 away from the drainage trough 1002 is inclined along the direction of the drainage trough 1002, and the protrusion 12 is constructed on the inclined structural surface of the circular frame plate 1001. As shown in the figure, when water seepage occurs on both sides of the frame plate 5 adjacent to the A end, the inclined structure of the drainage trough 1002 can effectively guide the rainwater into the drainage trough 1002, further improving the collection effect of rainwater seepage.

[0049] like Figure 10As shown, in some embodiments, a collecting groove 15 is formed between the lowest end of the upper surface of the circular frame 1001 and the light-transmitting groove 3, and the drainage groove 11 is opened through the wall thickness of the roof panel 1, and the highest end of the drainage groove 11 is connected to 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, and 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 into the outside world.

[0050] like Figure 6 and Figure 9 As shown, in some embodiments, the support frame 6 includes two right-angle inserts 601 and a right-angle insert rod 602, and the two right-angle inserts 601 are diagonally distributed and the two ends are respectively slidably matched with one end of the two right-angle insert rods 602 to form a circular closed area. The right-angle insert rod 602 and the right-angle insert 601 are both constructed with connecting protrusions 603 at the corners, and the connecting protrusions 603 are provided with through holes 604, that is, the connecting protrusions 603 can be installed on the inner panel surface of the roof panel 1 by bolts, and the design of the right-angle insert rod 602 and the right-angle insert 601 can adjust the size of the circular closed area of the support frame 6 according to the size of the light-transmitting groove 3, thereby improving applicability.

[0051] like Figure 6 and Figure 9 As shown, in some embodiments, one side of the right-angle insert 601 in the length direction is open, and one side of the right-angle insert rod 602 in the length direction is flush with the open end of the right-angle insert 601, that is, the open end of the right-angle insert 601 is directly in contact with the inner sealing layer 7 of the right-angle insert rod 602. The design of the open end of the right-angle insert 601 increases the force-bearing area with the inner sealing layer 7, further improving the sealing effect.

[0052] like Figure 9 As shown, in some embodiments, a partition 16 connected to the steel structure support assembly of the factory building is also included. In this embodiment, the partition 16 can be installed on the roof beam. The partition 16 is located below the roof panel 1. The upper surface of the partition 16 is provided with an insulation layer 17. The insulation layer 17 is located between the roof panel 1 and the partition 16. The design of the insulation layer 17 improves the insulation effect in the factory building.

[0053] like Figure 9 As shown, in some embodiments, the insulation layer 17 is made of glass wool material, and the partition 16 is made of mineral wool material. Glass wool material has good high temperature resistance, and the partition 16 is made of mineral wool material with good sound insulation effect, thereby reducing noise in the factory.

[0054] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one 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. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
