Description

Technical Field

[0001] This utility model belongs to the field of skylight technology, and in particular relates to a horizontal sunken skylight structure for industrial plants. Background Technology

[0002] Factory buildings typically require ample natural light to ensure the smooth operation of production activities. Skylights allow natural light to enter the factory interior directly, increasing indoor illumination and reducing reliance on artificial lighting during the day, thereby lowering lighting energy consumption and saving energy costs.

[0003] In existing skylights, the glass is fixed to the frame using structural adhesive. When the glass breaks, the organic polymer film in the middle holds the broken glass fragments together, preventing them from falling and thus providing safety. When broken glass is discovered, it needs to be replaced to avoid affecting light transmission. However, using structural adhesive makes replacing these glass pieces inconvenient and cumbersome. Therefore, we propose a horizontally recessed skylight structure for industrial plants. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontally sunken skylight structure for industrial plants to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a horizontal sunken skylight structure for industrial plants, including a roof slab and further comprising:

[0006] The mounting frame is inserted into the roof of the factory building. Two connecting blocks are fixedly installed on both sides of the mounting frame. A first bolt is threaded into the connecting block, and one end of the first bolt extends into the roof of the factory building.

[0007] A first circular plate is fixedly installed inside the mounting frame. A first annular sealing gasket is fixedly installed on the top of the first circular plate. A second annular plate is fixedly installed inside the mounting frame and above the first annular sealing gasket. A second annular sealing gasket is fixedly installed at the bottom of the second annular plate. Tempered glass is provided between the first annular sealing gasket and the second annular sealing gasket. Two drain pipes are fixedly installed inside the second annular sealing gasket. One end of each drain pipe passes through the inner wall of the mounting frame and extends to the outside.

[0008] A fixing component is located inside the roof of the factory building and is used to fix the second annular plate.

[0009] In this technical solution, during installation, the worker can place the mounting frame into the mounting holes on the factory roof panel. At this time, the four connecting blocks will be located on top of the factory roof panel. Then, the four connecting blocks can be fixed to the top of the factory roof panel using four first bolts and a wrench. Subsequently, waterproof structural adhesive can be applied to the connection between the mounting frame and the factory roof panel. Then, the worker can place the tempered glass on top of the first annular sealing gasket, and then place the second annular plate inside the mounting frame. Then, the fixing component is used to fix the second annular plate. At this time, the second annular sealing gasket will deform under pressure, and the first annular sealing gasket will also deform under pressure, thereby fixing the tempered glass. With the cooperation of the first and second annular sealing gaskets, water leakage can be avoided.

[0010] In the above technical solution, the fixing component further includes:

[0011] Several grooves are provided, all of which are formed within the mounting frame and located above the second annular plate. A rotating plate is rotatably mounted in each groove. A third bolt is threaded onto the end of the rotating plate away from the groove. One end of the third bolt is in close contact with the top of the second annular plate. A limit groove is provided in each groove.

[0012] Two first baffles are located at the top of the mounting frame. Two second baffles are provided at the top of the mounting frame. The two ends of the second baffles are respectively located at the top of one end of the two first baffles. A second bolt is installed on the internal thread of the second baffle. One end of the second bolt passes through one end of the first baffle and extends into the mounting frame. Several limiting rods are fixedly installed at the bottom of the second baffles and the bottom of the first baffles. One end of the limiting rod passes through the top of the mounting frame and extends into the corresponding limiting groove.

[0013] In this technical solution, during fixing, the second bolts on the second baffle can be removed with a wrench. Then, the first and second baffles can be removed from the top of the mounting frame, allowing the limiting rods to be pulled out of their corresponding limiting grooves. At this point, the rotating plate will be released from its fixed position. The operator can then rotate and open the rotating plate, positioning it above the second annular plate. After rotating all the rotating plates 90° outwards, the first and second baffles are returned to their original positions. The limiting rods at the bottom of the first and second baffles will then re-insert into their corresponding limiting grooves, fixing the rotating plate and preventing further rotation. Subsequently, the two second baffles can be secured using the four second bolts and a wrench. The first baffle and two second baffles are fixed to the top of the factory roof. Then, the workers can install the thread of the third bolt in the end of the rotating plate away from the groove. Then, the third bolt can be turned with a wrench to make the third bolt move downward until one end of the third bolt contacts the top of the second annular plate and presses the second annular plate downward. At this time, the second annular sealing gasket will deform under the pressure, and the first annular sealing gasket will also deform under the pressure. When turning several third bolts, they can be turned evenly. Do not turn one of the third bolts to the point that it cannot be turned. At this time, the tempered glass will be fixed. With the cooperation of the first annular sealing gasket and the second annular sealing gasket, water leakage can be avoided.

[0014] In the above technical solution, one end of the limiting rod is inserted into the mounting frame, the second bolt is threadedly connected to the mounting frame, and the second bolt is threadedly connected to the first baffle.

[0015] In this technical solution, it is ensured that one end of the limiting rod can be inserted into the mounting frame, that the second bolt can be threaded into the mounting frame, and that the second bolt can be threaded into the first baffle.

[0016] In the above technical solution, two drain pipes are further fixedly installed inside the second annular sealing gasket, one end of which penetrates the inner wall of the mounting frame and extends to the outside.

[0017] In this technical solution, the rainwater on the top of the tempered glass can be discharged to the outside through the action of two drainage pipes.

[0018] In the above technical solution, furthermore, the cross-section of the limiting groove and the cross-section of the limiting rod are both rectangular.

[0019] In this technical solution, the position of the rotating plate is fixed after one end of the limiting rod is inserted into the limiting groove.

[0020] Furthermore, in the above technical solution, the mounting frame and the connecting block are integrally formed structures.

[0021] In this technical solution, the structural stability between the mounting frame and the connecting block is ensured.

[0022] In the above technical solution, the first bolt is further threadedly connected to the roof of the factory building.

[0023] In this technical solution, it is ensured that the first bolt can be threaded into the roof of the factory building.

[0024] The beneficial effects of this utility model are:

[0025] The industrial plant uses a horizontal sunken skylight structure. Through the cooperation of the installation frame, the first circular plate, the first annular sealing gasket, the second annular sealing gasket, the second annular plate, and the fixing components, structural adhesive is not required when installing tempered glass. This makes it easy to disassemble the tempered glass and avoids the inconvenience of replacing broken tempered glass, which would affect the light transmission of the plant.

Then, the worker places the tempered glass 3 on top of the first annular sealing gasket 7, and then places the second annular plate 10 inside the mounting frame 2. Then, the fixing components are used to fix the second annular plate 10. At this time, the second annular sealing gasket 9 will deform under pressure, and the first annular sealing gasket 7 will also deform under pressure, thereby fixing the tempered glass 3. With the cooperation of the first annular sealing gasket 7 and the second annular sealing gasket 9, water leakage can be avoided. Example 2

[0045] Several grooves 16 are provided in the mounting frame 2 and are located above the second annular plate 10. A rotating plate 14 is rotatably installed in the groove 16. A third bolt 15 is threaded on the end of the rotating plate 14 away from the groove 16. One end of the third bolt 15 is in close contact with the top of the second annular plate 10. A limit groove 17 is provided in the groove 16.

[0046] Two first baffles 11 are located at the top of the mounting frame 2. Two second baffles 12 are provided at the top of the mounting frame 2. The two ends of the second baffles 12 are respectively located at the top of one end of the two first baffles 11. A second bolt 8 is installed on the internal thread of the second baffle 12. One end of the second bolt 8 passes through one end of the first baffle 11 and extends into the mounting frame 2. Several limiting rods 18 are fixedly installed at the bottom of the second baffles 12 and the bottom of the first baffles 11. One end of the limiting rod 18 passes through the top of the mounting frame 2 and extends into the corresponding limiting groove 17.

[0047] During fixing, the second bolt 8 on the second baffle 12 can be removed with a wrench. Then, the first baffle 11 and the second baffle 12 can be removed from the top of the mounting frame 2, allowing the limiting rod 18 to be pulled out from the corresponding limiting groove 17. At this time, the rotating plate 14 will be released from fixing. Then, the operator can rotate and open the rotating plate 14, so that the rotating plate 14 is rotated above the second annular plate 10. After rotating all the rotating plates 14 outward by 90°, the first baffle 11 and the second baffle 12 are returned to their original positions. At this time, the limiting rod 18 at the bottom of the first baffle 11 and the second baffle 12 will be inserted into the corresponding limiting groove 17 again. At this time, the rotating plate 14 will be fixed and will not rotate. Then, the two baffles can be fixed by using the four second bolts 8 and a wrench. The first baffle 11 and the two second baffles 12 are fixed to the top of the factory roof 1. Then, the workers can install the thread of the third bolt 15 into the end of the rotating plate 14 away from the groove 16. Then, the third bolt 15 can be rotated with a wrench to make the third bolt 15 move downward until one end of the third bolt 15 contacts the top of the second annular plate 10 and squeezes the second annular plate 10 to move downward. At this time, the second annular sealing gasket 9 will deform under the pressure, and the first annular sealing gasket 7 will also deform under the pressure. When rotating several third bolts 15, they can be rotated evenly. Do not rotate one of the third bolts 15 to the point that it cannot be rotated. At this time, the tempered glass 3 will be fixed. With the cooperation of the first annular sealing gasket 7 and the second annular sealing gasket 9, water leakage can be avoided. Example 3

In addition to the technical solutions of the above embodiments, it also has the following technical features: the cross-section of the limiting groove 17 and the cross-section of the limiting rod 18 are both rectangular.

[0053] Specifically, this ensures that once one end of the limiting rod 18 is inserted into the limiting groove 17, the position of the rotating plate 14 can be fixed. Example 6

[0054] This embodiment provides a horizontal sunken skylight structure for industrial plants. In addition to the technical solutions of the above embodiments, it also has the following technical features: the mounting frame 2 and the connecting block 4 are integrally formed structures.

[0055] Among these measures, it is essential to ensure the structural stability between the mounting frame 2 and the connecting block 4. Example 7

[0056] This embodiment provides a horizontal sunken skylight structure for industrial plants. In addition to the technical solutions of the above embodiments, it also has the following technical features: the first bolt 5 is threadedly connected to the roof plate 1 of the plant.

[0057] Specifically, it is ensured that the first bolt 5 can be threaded into the roof slab 1 of the factory building.

[0058] Working principle: During installation, the worker can place the mounting frame 2 into the mounting holes on the factory roof 1. At this time, the four connecting blocks 4 will be located on top of the factory roof 1. Then, the four connecting blocks 4 can be fixed to the top of the factory roof 1 using the four first bolts 5 and a wrench. Then, waterproof structural adhesive can be applied to the connection between the mounting frame 2 and the factory roof 1. Then, the worker can place the tempered glass 3 on top of the first annular sealing gasket 7, and then place the second annular plate 10 in the mounting frame 2. In the initial state, the third bolt 15 is not installed on the rotating plate 14, and the rotating plate 14 is located in the groove 16. Several bolts at the bottom of the second baffle 12 are not installed on the rotating plate 14. The limiting rods 18 and several limiting rods 18 at the bottom of the first baffle 11 will fix the corresponding rotating plate 14 in the corresponding groove 16, thereby ensuring that the rotating plate 14 will not obstruct the placement of the tempered glass 3. At this time, the second annular sealing gasket 9 at the bottom of the second annular plate 10 will contact the top of the tempered glass 3, and the top of the second annular plate 10 will be located below the groove 16. Subsequently, the second bolt 8 on the second baffle 12 can be removed with a wrench, and then the first baffle 11 and the second baffle 12 can be removed from the top of the mounting frame 2, so that the limiting rods 18 can be pulled out from the corresponding limiting grooves 17. At this time, the rotating plate 14 will be released from fixation, and then the operator can rotate the plate 14. Rotating plate 14 is rotated and opened, causing it to rotate above the second annular plate 10. After rotating all rotating plates 14 90° outwards, the first baffle 11 and the second baffle 12 are returned to their original positions. At this point, the limiting rods 18 at the bottom of the first baffle 11 and the second baffle 12 will re-insert into the corresponding limiting grooves 17, fixing the rotating plate 14 and preventing rotation. Then, using four second bolts 8 and a wrench, the two first baffles 11 and the two second baffles 12 are fixed to the top of the factory roof plate 1. Finally, the threaded part of the third bolt 15 is installed on the end of the rotating plate 14 furthest from the groove 16, allowing it to... Turn the third bolt 15 with a wrench to move it downwards until one end of the third bolt 15 contacts the top of the second annular plate 10 and presses the second annular plate 10 downwards. At this time, the second annular sealing gasket 9 will deform under pressure, and the first annular sealing gasket 7 will also deform under pressure. When turning several third bolts 15, the rotation can be even, and one of the third bolts 15 should not be turned to the point that it cannot be turned. At this time, the tempered glass 3 will be fixed. With the cooperation of the first annular sealing gasket 7 and the second annular sealing gasket 9, water leakage can be avoided. With the action of the two drain pipes 13, the rainwater on the top of the tempered glass 3 can be discharged to the outside.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
