DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Example

[0027] Reference Figure 1-3 As shown, a double-layer glass lighting top node of the present invention comprises:

[0028] Keel 2;

[0029] The inner layer structure comprises: a first glass layer 9, a first sealing member 13, and a first waterproof member 14, wherein the end of the first glass layer 9 is sealed and connected to the keel 2 through the first sealing member 13, and adjacent first glass layers 9 are sealed and connected through the first waterproof member 14;

[0030] The outer layer structure includes: a pressure plate assembly 7, a second waterproof component 15, a second glass layer 10, a second sealing component 8, a third waterproof component 16 and a conduit 5. The pressure plate assembly 7 is sealed and connected to the adjacent first glass layers 9 through the second waterproof component 15, the ends of the second glass layers 10 are sealed and connected to the pressure plate assembly 7 through the second sealing component 8, and the adjacent second glass layers 10 are sealed and connected through the third waterproof component 16. The conduit 5 is penetrated through the second waterproof component 15.

[0031] In the double-layer glass skylighting top node described in the present invention, in the inner layer structure, the first sealing member 13 prevents leakage between the end of the first glass layer 9 and the keel 2, and the first waterproof member 14 ensures the sealing between adjacent first glass layers 9. In the outer layer structure, the second waterproof member 15 ensures the sealing between the pressing plate assembly 7 and the first glass layer 9, the second sealing member 8 prevents leakage between the end of the second glass layer 10 and the pressing plate assembly 7, and the third waterproof member 16 ensures the sealing between adjacent second glass layers 10. In the height direction, the first glass layer 9 and the second glass layer 10 are sealed in sequence by the second waterproof member 15, the pressing plate assembly 7 and the second sealing member 8. It can solve the problem of smooth drainage of the skylight top without water leakage, and at the same time enhance the effect of heat insulation, sound insulation and heat preservation. The conduit 5 is arranged in the second waterproof member 15, and the drainage function between the first glass layer 9 and the second glass layer 10 is realized under the premise of ensuring sealing. Even if leakage occurs at the gap position of the second glass layer 10, the accumulated water can be discharged through the water conduit to ensure that the first glass layer 9 does not leak.

[0032] It also includes an embedded part 1, which is embedded in the indoor wall to be installed. The embedded part 1 is connected to an angle steel 4, and the keel 2 is fixedly connected to the embedded part 1 through the angle steel 4.

[0033] Reference Figure 3 The pressure plate assembly 7 shown includes: a first pressure plate 19, a second pressure plate 17 and an intermediate pressure plate, the first pressure plate 19 is arranged on the second waterproof part 15, the second pressure plate 17 is sealed and connected to the first pressure plate 19, the intermediate pressure plate is arranged between the first pressure plate 19 and the second pressure plate 17, the first pressure plate 19 and the second pressure plate 17 are arranged facing each other, and the side close to each other is provided with staggered serrated strips, which not only fixes the lower fireproof glass but also provides a fixing fulcrum for the upper glass.

[0034] The intermediate pressure plate is provided with a connection assembly, which includes: a connection piece 12, one end of which is provided on the keel 2 and the other end passes through the first waterproof member 14 and extends outward, and a bolt 20 which is provided in the pressure plate assembly 7 and connected to the connection piece 12. The keel 2 is the main supporting structure of the skylight roof, bearing the deadweight of the skylight roof and external loads. The keel 2 is firmly connected with the pressure plate assembly 7 through the connection assembly, which effectively improves the structural stability of the entire skylight roof node. When facing external loads such as strong winds and snow accumulation, the skylight roof node can maintain its structural integrity and is not easily deformed or damaged, thereby extending the service life of the skylight roof. The bolt 20 tightly connects the pressure plate assembly 7 with the connection piece 12 through the friction and clamping force generated by tightening, preventing the pressure plate assembly 7 from loosening or displacement during use. When the skylight roof is subjected to external force, the connection assembly can effectively transmit and disperse the external force, ensuring the stability and reliability of the entire skylight roof node structure.

[0035] One end of the bolt 20 abuts against the third waterproof member 16 and the other end passes through the middle pressure plate and the first pressure plate 19 in sequence and is connected to the connecting member 12. The connecting member 12 is provided with a threaded hole adapted for the bolt 20. The bolt 20 passes through the middle pressure plate and the first pressure plate 19 in sequence and is threadedly connected to the connecting member 12, so that these components form a stable overall structure.

[0036] The first pressing plate 19, the second pressing plate 17 and the middle piece are respectively provided with through holes for the connecting piece 12 to pass through, so that the connecting piece 12 can pass through smoothly. The second pressing plate 17 is also provided with a receiving platform, and the middle plate 18 is arranged on the receiving platform. The setting of the receiving platform provides clear positioning and support for the installation of the middle plate 18, so that the installation of the middle plate 18 is more convenient, quick and accurate.

[0037] Reference Figure 1-2 The keel 2, the first seal 13, the first glass layer 9, the second waterproof member 15, the pressure plate assembly 7, the second seal 8 and the second glass layer 10 are stacked and supported in sequence from bottom to top. There is a space 11 between the first glass layer 9 and the second glass layer 10. In terms of heat insulation, when the outside temperature changes, the air in the space 11 between the first glass layer 9 and the second glass layer 10 can play a buffering role, preventing heat from being directly transferred from the second glass layer 10 to the first glass layer 9, thereby reducing the indoor temperature fluctuation. In terms of sound insulation, when there is sound transmitted from the outside, the air in the space 11 can absorb and scatter part of the sound energy, reduce the propagation of sound, and achieve a sound insulation effect. The first waterproof member 14, the second waterproof member 15 and the third waterproof member 16 are all silicone weather-resistant glue, and are filled in the corresponding gaps to form glue seam seals. The first seal 13 is a fireproof sealant and a fireproof pad. The fire resistance limit of the first glass layer 9 and the keel 2 is not less than one hour.

[0038] One end of the conduit 5 is located in the partition 11, and the other end of the conduit 5 extends to the adjacent partition 11 through the second waterproof member 15. The conduit 5 in the outermost partition 11 extends downward through the corresponding second waterproof member 15. When water accumulates in the partition 11, the accumulated water will flow to the end of the conduit 5 located in the partition 11 under the action of gravity. After the conduit 5 collects the accumulated water, it passes through the second waterproof member 15 at its other end and guides it to the adjacent partition 11. In the adjacent partition 11, the accumulated water continues to flow along the conduit 5, and thus passes through the conduits 5 in each partition 11 in turn until it reaches the outermost partition 11. The conduit 5 in the outermost partition 11 extends downward through the corresponding second waterproof member 15, and finally discharges the accumulated water from the skylight top node, enters the drainage system of the building, or discharges it to a suitable location such as the ground, thereby completing the entire drainage process.

[0039] Reference Figure 1 The embedded parts 1 and angle steel 4 are connected to the end of the keel 2, and the end of the outermost second glass layer 10 is also connected to the indoor wall to be installed through the sub-frame 6. The end of the outermost second glass layer 10 is connected to the indoor wall through the sub-frame 6. The sub-frame 6 provides support and fixation for the second glass layer 10, so that it can maintain a stable position under various environmental conditions. The lighting top node is kept stable by the connection of the keel 2, angle steel 4 and embedded parts 1, and will not be displaced or deformed.

[0040] The first glass layer 9 is fireproof glass, and the thickness of the first glass layer 9 is greater than that of the second glass layer 10. When a fire occurs, as the fire spreads, the temperature gradually rises. At this time, the first glass layer 9 as fireproof glass begins to play a role. The fireproof interlayer material inside it undergoes expansion, carbonization and other reactions under the action of high temperature, forming a layer of heat insulation barrier to prevent flames and high temperatures from spreading into the room through the glass layer. At the same time, the thicker first glass layer 9 can maintain a lower temperature for a longer time due to its better heat insulation performance, providing more time for the evacuation of indoor personnel and the rescue of firefighters. In this process, although the thickness of the second glass layer 10 is relatively small, it can also play a role in blocking fire and heat to a certain extent, and together with the first glass layer 9, it constitutes a double-layer protection structure, which improves the overall fireproof performance of the skylight.

[0041] Reference Figure 1-2The keel 2 shown is configured as a steel square tube, which is sprayed with fireproof paint, and a fireproof skylight with fireproof glass is set on it. A customized steel connector 12 door is set in the middle of the steel square tube. The steel pressure plate assembly 7 is used to fix the lower fireproof glass and provide a fixing fulcrum for the upper glass. After the fireproof glass is fixed, silicone weather-resistant glue (the third waterproof component 16) is first applied to the position of the partition seam, and silicone weather-resistant glue (the second waterproof component 15) is applied to the side where the customized steel pressure plate and the fireproof glass are fixed. The upper glass is fixed with structural glue and aluminum alloy auxiliary frame in the factory. It is maintained according to the prescribed time to meet the bearing capacity of the structural glue and then transported to the site for installation on the customized connection support of the lower fireproof glass skylight, and then the pressure plate assembly 7 is used to fix the glass auxiliary frame. The pressure plate assembly 7 uses screws to fix the customized steel connector 12 and then fix the upper glass. A layer of silicone weather-resistant glue (the first and third waterproof components 16) is applied to the partition seam position of the glass panel. If leakage occurs at the gap of the upper glass skylight, the water in the cavity between the first and second skylights is discharged to the outside through the conduit 5, ensuring that the lower glass skylight does not leak. It can solve the problem of smooth drainage of the skylight and prevent water leakage, and at the same time enhance the effect of heat insulation, sound insulation and thermal insulation.

[0042] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
