Technical Field
[0001] This utility model belongs to the field of building construction technology, and in particular relates to a building skylight roof structure. Background Technology
[0002] A skylight is a building structure applied to the top of a building primarily to achieve natural lighting. It typically consists of a frame and light-transmitting materials. The frame is often made of metal to provide stable support, while the light-transmitting materials, such as glass or PC panels, have good light transmission. Skylights can effectively introduce natural light, reduce energy consumption for artificial lighting, and create bright and open interior spaces. They are widely used in various types of buildings, such as commercial centers, stadiums, and residences. Their design must take into account multiple aspects, including lighting effects, structural safety, waterproofing, and heat insulation, to improve the overall performance and comfort of the building.
[0003] A common practice in existing technologies is to continuously lay large-sized glass or PC panels on the roof using splicing joints. Due to limitations in the size, transportation, and installation of individual light-transmitting materials, splicing becomes inevitable, which concentrates the issues of sealing, waterproofing, and structural connection at the joints and supports. Analysis of existing engineering cases and technical documents reveals that the technical problems in current building designs are: the joints rely on sealants, caulking materials, or rubber strips, which age and crack after prolonged exposure to ultraviolet rays, temperature differences, and rainwater, easily leading to leakage. Utility Model Content
[0004] The purpose of this utility model is to provide a building skylight roof structure. The technical problem to be solved is that the joints of the glass panels rely on sealant for sealing, which ages and cracks after being exposed to ultraviolet rays, temperature differences and rainwater for a long time, leading to leakage.
[0005] This invention employs supporting steel beams and side supporting steel beams to construct a stable support frame, providing reliable support for the ultra-clear laminated insulated glass and ensuring stable installation. Furthermore, through the combined use of various materials, multiple sealing treatments are applied to the glass and the frame, as well as between the glass panes, significantly improving sealing performance and effectively preventing rainwater leakage and air infiltration, thus solving the aforementioned problems.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A building skylight roof structure includes supporting steel beams; side supporting steel beams are installed on both sides of the top of the supporting steel beams; the top of the side supporting steel beams is covered with ultra-clear laminated insulated glass; a connecting component is provided on one side of the two side supporting steel beams facing each other; the connecting component includes an aluminum alloy main frame; both sides of the aluminum alloy main frame are welded and fixed to the side supporting steel beams; both sides of the aluminum alloy main frame are respectively attached to the two side supporting steel beams; and aluminum alloy sub-frames are assembled on both sides of the top of the aluminum alloy main frame. A sealing gasket is bonded to the top of the aluminum alloy sub-frame, and the top of the sealing gasket is bonded and fixed to the edge of the ultra-clear laminated insulated glass. A first weather-resistant silicone sealant is applied to the top of the aluminum alloy sub-frame, and the first weather-resistant silicone sealant covers the joint between the ultra-clear laminated insulated glass and the aluminum alloy sub-frame. An aluminum alloy pressure plate is provided between the two aluminum alloy sub-frames, and a stainless steel bolt is provided through the top of the aluminum alloy pressure plate. A pressure-bearing component is integrally stamped on one side of each of the two aluminum alloy sub-frames, and the bottom of the aluminum alloy pressure plate is pressed onto the top of the pressure-bearing component.
[0007] The present invention, as described above, is used for a building skylight roof structure. Further, the bottom sides of the aluminum alloy main frame are integrally formed with connecting plates, and the top of the supporting steel beam is welded with a U-shaped steel channel, which is engaged between the two connecting plates.
[0008] The present invention, as described above, is used for a building skylight roof structure. In a further step, an aluminum alloy bolt is provided through one side of the U-shaped steel channel, and the connecting plate and the U-shaped steel channel are fixedly connected by the aluminum alloy bolt.
[0009] The present invention, as described above, is used for a building skylight roof structure. Further, a first rubber sealing strip is pressed onto one side of each of the two ultra-white laminated insulated glass units, and the surface of the first rubber sealing strip is filled with a second weather-resistant silicone sealant.
[0010] The present invention provides a further feature for a building skylight roof structure as described above: expansion joints are provided at both ends of the front side of the aluminum alloy main frame.
[0011] The present invention, as described above, is used for a building skylight roof structure. Further, the bottom of the aluminum alloy sub-frame is integrally stamped with a slot, and a second rubber sealing strip is inserted into the inner cavity of the slot.

[0014] By applying a first rubber sealing strip and a second weather-resistant silicone sealant between adjacent laminated insulated glass units, a primary seal is achieved for the glass joints. Simultaneously, the first weather-resistant silicone sealant is applied to the joint between the laminated insulated glass and the aluminum alloy sub-frame, achieving a secondary seal and preventing rainwater from seeping into the building's interior through the glass joints. This invention solves the technical problem of glass panel joints relying on sealant for sealing, which ages and cracks after prolonged exposure to ultraviolet radiation, temperature differences, and rainwater, leading to leakage.
[0015] By using the supporting steel beams and side supporting steel beams together, a stable supporting frame is provided for the ultra-clear laminated insulated glass.

This allows the ultra-clear laminated insulated glass to be stably installed on top of the supporting steel beams and the side supporting steel beams. By sealing the junction of the two ultra-clear laminated insulated glass units, the goal of stable and reliable installation and strong sealing performance can be achieved.

A foam strip 13 is pressed and installed between the aluminum alloy sub-frame 42 and the aluminum alloy main frame 41. The top of the aluminum alloy main frame 41 is stamped and integrally formed with a limiting groove 14. The rear end of the stainless steel bolt 46 is engaged in the inner cavity of the limiting groove 14. A sealing gasket 44 is bonded to the top of the aluminum alloy sub-frame 42. The top of the sealing gasket 44 is bonded and fixed to the edge of the ultra-clear laminated insulating glass 3. A first weather-resistant silicone sealant 43 is applied to the top of the aluminum alloy sub-frame 42.

An aluminum alloy pressure plate 45 is provided between the two aluminum alloy sub-frames 42. A stainless steel bolt 46 is provided through the top of the aluminum alloy pressure plate 45. A pressure-bearing component 47 is stamped and integrally formed on one side of the two aluminum alloy sub-frames 42. The bottom of the aluminum alloy pressure plate 45 is pressed onto the top of the pressure-bearing component 47.
[0022] refer to Figure 1 The above-mentioned building skylight roof structure of this utility model is further improved by: pressing a first rubber sealing strip 8 on one side of each of the two ultra-white laminated insulated glass units 3, and filling the surface of the first rubber sealing strip 8 with a second weather-resistant silicone sealant 9.
[0023] By applying a first rubber sealing strip and a second weather-resistant silicone sealant between adjacent laminated insulated glass units, a primary seal is achieved for the glass joints. Simultaneously, the first weather-resistant silicone sealant is applied to the joint between the laminated insulated glass and the aluminum alloy sub-frame, achieving a secondary seal and preventing rainwater from seeping into the building's interior through the glass joints. This invention solves the technical problem of glass panel joints relying on sealant for sealing, which ages and cracks after prolonged exposure to ultraviolet radiation, temperature differences, and rainwater, leading to leakage.
[0024] refer to Figure 1 , Figure 2 and Figure 4 Expansion joints 10 are provided at both ends of the front side of the aluminum alloy main frame 41.
[0025] The above solution is adopted: by setting the expansion joint 10, there is a certain expansion space between the aluminum alloy main frame 41 and the side support steel beam 2, thereby effectively preventing damage to the aluminum alloy sub-frame 42 and the all-white laminated insulated glass 3 caused by the vibration of the side support steel beam 2.
[0026] refer to Figure 2 and Figure 3 The bottom of the aluminum alloy sub-frame 42 is integrally stamped with a slot 11, and a second rubber sealing strip 12 is inserted into the inner cavity of the slot 11. The bottom of the second rubber sealing strip 12 is pressed onto the surface of the aluminum alloy main frame 41.
[0027] By adopting the above solution, the aluminum alloy sub-frame 42 and the aluminum alloy main frame 41 are sealed in contact through the cooperation of the slot 11 and the second rubber sealing strip 12, thereby sealing the periphery of the stainless steel bolt 46 and effectively preventing external factors from affecting the stability of the stainless steel bolt 46.
[0028] Working Principle: In use, the user constructs the supporting steel beam 1 and the side supporting steel beam 2, then welds the aluminum alloy main frame 41 between the two side supporting steel beams 2, thus fixing the side supporting steel beams 2 and the aluminum alloy main frame 41. The user then engages the aluminum alloy sub-frame 42 on both sides of the top of the aluminum alloy main frame 41, presses the aluminum alloy pressure plate 45 onto the top of the pressure-bearing component 47, and allows the stainless steel bolt 46 to penetrate into the inner cavity of the limiting groove 14. The nut of the stainless steel bolt 46 is locked in the limiting groove 14. Rotating the stainless steel bolt 46 then pushes the aluminum alloy pressure plate 45 downwards via a thread, generating a reverse pull that causes the aluminum alloy... The pressure plate 45 is stably pressed onto the top of the pressure-bearing component 47. Then, the user adheres the sealing gasket 44 to the top of the aluminum alloy sub-frame 42 and lays the ultra-clear laminated insulating glass 3, so that the surface of the ultra-clear laminated insulating glass 3 is bonded and fixed to the top of the sealing gasket 44. The first weather-resistant silicone sealant 43 is applied between the sealing gasket 44, the ultra-clear laminated insulating glass 3 and the sealing gasket 44 to seal the ultra-clear laminated insulating glass 3 and the aluminum alloy sub-frame 42. Finally, the first rubber sealing strip 8 is pressed between the two ultra-clear laminated insulating glass 3 in sequence, and the second weather-resistant silicone sealant 9 is applied to the top of the first rubber sealing strip 8 to seal again.
[0029] In summary, the building's skylight roof structure, through the combined use of supporting steel beams 1 and side supporting steel beams 2, provides a stable support frame for the ultra-clear laminated insulated glass 3. Simultaneously, the combined use of connecting components 4, connecting plates 5, and U-shaped steel channels 6 allows for the assembly and fixation of the ultra-clear laminated insulated glass 3 and the side supporting steel beams 2. This ensures the ultra-clear laminated insulated glass 3 is stably installed on top of the supporting steel beams 1 and side supporting steel beams 2, and the junction of the two ultra-clear laminated insulated glass 3 is sealed, thus achieving stable and reliable installation and strong sealing performance.
