Description

Technical Field

[0001] This invention relates to the field of roof skylight technology, specifically to a roof wind-resistant and pressure-relief skylight and its application. Background Technology

[0002] Metal roofing panels possess advantages such as lightweight, high strength, corrosion resistance, and aesthetic appeal, and have been widely used in large-scale buildings such as high-speed rail platforms, convention centers, and stadiums in recent years. As a crucial component of metal roofing, the wind resistance and waterproofing functions of skylights are of paramount importance.

[0003] The wind pressure distribution on the roof surface is mainly influenced by the turbulence inherent in the structure itself. Airflow separation occurs at the highest point of the roof, resulting in significant negative pressure. Simulations were conducted to assess the wind pressure distribution on the roof in different directions. Furthermore, the current "Load Code for Building Structures" (GB 50009-2012) also indicates that the negative pressure is greater at the highest point of the roof. Figure 9 As shown. Compared to skylights on flat roofs and pitched roofs, skylights at the ridge are subject to more complex stress conditions. They are more susceptible to instability due to negative wind pressure, making them unable to withstand strong wind loads and causing problems such as deformation and leakage.

[0004] Currently, there are generally no wind-resistant and pressure-relief treatments specifically designed for roofs to withstand wind pressure. Most solutions involve adding reinforcement structures to the ridge. For example, in existing patent literature with publication number CN214169604U, entitled "A Wind-Resistant and Snow-Proof Ridge Structure for Metal Roofs," it is specifically disclosed that "ridge plugs are fixed to the upper metal profiled steel sheets on two opposite roof surfaces; the shape of the ridge plugs matches the valley shape of the upper metal profiled steel sheets on the roof, and the ridge plugs are connected to the peak of the slope on the upper surface of the upper metal profiled steel sheets on the roof; the ridge plugs are connected and fixed to the valley of the slope on the upper surface of the upper metal profiled steel sheets on the roof." The joints are fitted with butyl tapes facing each other, with a gap between the two tapes. The patent document states that by utilizing specially shaped ridge end caps and metal ridge tiles, a special butyl tape laying method, and a unique connection method, the entire metal roof ridge structure is made more robust, effectively solving minor air and snow leaks. However, the patent document also notes that in the event of a blizzard, the ridge skylights may deform under wind loads. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to solve the problem that roof skylights are easily damaged by wind pressure.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A roof wind-resistant pressure relief skylight includes a skylight installed on the roof, with pressure relief adjustment devices installed at the four corners of the skylight, and pressure sensors also installed on the skylight.

[0008] The pressure relief regulating device includes an inner sleeve rod and an outer sleeve. The top of the inner sleeve rod is connected to a square tube, and the bottom of the outer sleeve is fixed to the roof. The bottom of the inner sleeve rod is slidably connected inside the outer sleeve. A pressure relief hole is opened on the outer sleeve. The upper part of the outer sleeve is connected to the square tube through an elastic element, and the top of the square tube is fixed to the skylight.

[0009] This application incorporates sliding sleeve pressure relief components at the four corners of the skylight. These components effectively address roof ridge deformation caused by excessive loads from strong winds. The outer sleeve features pressure relief holes and incorporates elastic elements that work in conjunction with pressure sensors. When the generated negative wind pressure exceeds the pressure set by the pressure relief device, the pressure relief adjustment device activates. Once the pressure relief is complete, the elastic elements pull back, promptly closing the adjustment device. Conversely, when the generated negative wind pressure falls below the set pressure, the skylight may already be damaged. In this case, the elastic elements spring back the pressure relief device, activating the adjustment device to release pressure and ensuring the skylight at the roof ridge maintains good load-bearing capacity.

[0010] As a further aspect of the present invention: the pressure relief regulating device further includes a single plate and a support plate, one end of the single plate being connected to a square tube via the support plate, the square tube being located on the side of the skylight.

[0011] As a further aspect of the present invention: a gasket is provided at the contact position between the inner sleeve rod and the outer sleeve, the gasket is fixed on the inner wall of the outer sleeve, and the gasket is located below the pressure relief hole.

[0012] As a further aspect of the present invention: flashing is provided on all four sides of the skylight, and the top of the flashing is fixed to the outer sleeve, while a gap is left between the bottom and the roof.

[0013] As a further aspect of the present invention: the bottom of the four sides of the skylight is fixed to the roof by a waterproof component.

[0014] As a further embodiment of the present invention: the seepage prevention component includes a corrugated plate and a corner splicing component. The corrugated plate is located at the bottom side of the skylight. One end of the corrugated plate is fixed to the skylight and the other end is fixed to the roof. The corner splicing between two adjacent corrugated plates is fixed by the corner splicing component.

[0015] As a further aspect of the present invention: the pleated plate includes an integrally formed skylight welding part, a vertical overlapping part, a pleated protrusion part, and a roof welding part. The skylight welding part is fixed to the bottom side of the skylight, the roof welding part is fixed to the roof, the end of the pleated protrusion part is fixed to the corner splice, and the vertical overlapping part is located between the pleated protrusion part and the roof welding part and is arc-shaped and fixed to the corner splice.

[0016] As a further aspect of the present invention: the corner splicing component includes an upper connecting part and an arc-shaped overlapping part. The upper connecting part is located at the top of the arc-shaped overlapping part, and the upper connecting part includes two vertically shaped welding edges. The two welding edges are fixed to the bottom of the two side edges of the skylight, and the arc-shaped overlapping part connects two adjacent pleated plates.

[0017] This application also discloses the application of roof wind-resistant pressure relief skylights at the roof ridge.

[0018] This application also discloses the application of roof wind-resistant pressure relief skylights on pitched roofs.

[0019] As a further aspect of the present invention, it also includes a second anti-seepage component located at the junction of the skylight and the slope of the sloping roof. The second anti-seepage component includes an anti-seepage board and an anti-seepage splicing board. One end of the anti-seepage board is connected to the side of the skylight, and the other end is fixed to the roof through the anti-seepage splicing board.

[0020] As a further aspect of the present invention: the seepage-proof board has a "C" shaped structure, and the seepage-proof splicing board has an "S" shaped structure.

[0021] This application also discloses the application of roof wind-resistant and pressure-relief skylights in flat roofs.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Firstly, this application incorporates sliding sleeve pressure relief components at the four corners of the skylight. These components effectively address the deformation at the ridge caused by excessive load-bearing capacity due to strong winds. Pressure relief holes are located on the outer sleeve, incorporating elastic elements that work in conjunction with pressure sensors. When the generated negative wind pressure exceeds the pressure set by the pressure relief device, the pressure relief adjustment device activates. After pressure relief is complete, the elastic elements pull back, promptly closing the adjustment device. Conversely, when the generated negative wind pressure falls below the pressure set by the pressure relief device, the skylight may already be damaged. In this case, the elastic elements spring back the pressure relief device, activating the adjustment device to release pressure, ensuring the skylight at the ridge maintains good load-bearing capacity.

[0024] Secondly, this application uses horizontal pleated panels to splice the skylight on all four sides with the roof. The horizontal pleats greatly increase the contact area at the splice, making the contact more reliable. At the same time, the horizontal pleats extend the water seepage path at the joint between the skylight and the roof, which can promptly drain the turbulent water flow during heavy rain and snow, effectively improving the waterproof performance at the joint between the bottom of the skylight and the metal roof panel.

[0025] Finally, this application addresses the issue of leakage caused by rainwater accumulation at the joint between the skylight and the sloping roof, effectively shifting the leakage point upwards in conjunction with the flashing. An S-shaped waterproofing splice is installed between the C-shaped waterproofing board and the roof, ensuring a smooth transition and reducing misalignment caused by stress concentration. Rivets are used to connect the C-shaped waterproofing board, S-shaped waterproofing splice, and the roof, and sealant is applied. Alternatively, bolts or welding can be used for fixing, reducing the contact area between the C-shaped waterproofing board and the roof for a more secure connection. Furthermore, honeycomb gaskets are installed at the joint between the S-shaped waterproofing splice and the roof to effectively address cracking at the skylight-to-roof joint under temperature stress. When a joint breaks, the honeycomb layer ensures the gasket has good extensibility, effectively mitigating deformation and improving waterproofing performance. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: A wind-resistant pressure-relief skylight applied to the ridge of a roof includes a skylight 1, a pressure relief regulating device 2, a waterproof component 3, a flashing 4, and a pressure sensor 7. The skylight 1 is installed at the ridge of the roof 5. Figure 8 It can be seen that the ridge is the highest point and bears the greatest negative wind pressure. Therefore, this application sets pressure relief adjustment devices 2 at the four corners of the skylight 1 at the ridge. Since the negative wind pressure is the greatest at the ridge, setting the pressure relief adjustment device 2 at the ridge is the optimal embodiment. When there is a change in the shape of the ridge, the pressure relief adjustment device 2 is more suitable for the skylight at the ridge. It can balance the negative wind pressure borne by the skylight 1. When the generated negative wind pressure exceeds the pressure set by the pressure relief adjustment device 2, it can be relieved through the pressure relief adjustment device 2. After the pressure relief is completed, the elastic element in the pressure relief adjustment device 2 will generate a pull-back action and close the pressure relief adjustment device 2 in time. When the generated negative wind pressure is lower than the pressure set by the pressure relief adjustment device 2, the skylight may have been damaged. At this time, the elastic element in the pressure relief adjustment device 2 will pop up the pressure relief device and open the pressure relief hole to relieve pressure, ensuring that the skylight at the ridge has good load-bearing performance.

[0038] Furthermore, a pressure sensor 7 is also installed on the inside of the sunroof 1, which can monitor the wind pressure that the sunroof 1 is subjected to in real time.

[0039] Reference Figure 1 andFigure 2 The pressure relief regulating device 2 includes a square tube 21, an elastic element 22, a pressure relief hole 23, a support plate 24, a single plate 25, an inner sleeve rod 26, and an outer sleeve 27. The top of the inner sleeve rod 26 is connected to the square tube 21, and the bottom of the outer sleeve 27 is fixed to the roof 5. The bottom of the inner sleeve rod 26 is slidably connected inside the outer sleeve 27. The pressure relief hole 23 is opened on the outer sleeve 27. The top of the outer sleeve 27 is connected to the square tube 21 through the elastic element 22. The top of the square tube 21 is fixed to the skylight 1. One end of the single plate 25 is connected to the square tube 21 through the support plate 24. The square tube 21 is located on the side of the skylight 1. A gasket is also provided at the contact position between the inner sleeve rod 26 and the outer sleeve 27. The gasket is fixed on the inner wall of the outer sleeve 27 and is located below the pressure relief hole 23. The gasket here can be a sealing gasket to prevent water from entering the gap between the inner sleeve rod 26 and the outer sleeve 27, which would affect subsequent use. When the inner sleeve rod 26 slides upward inside the outer sleeve 27, the pressure relief hole 23 will be exposed, and pressure relief can be achieved at this time. When the inner sleeve rod 26 slides downward inside the outer sleeve 27, the pressure relief hole 23 will be blocked, and sealing can be achieved at this time.

[0040] When external negative wind pressure acts on the skylight 1 at the roof ridge, it will cause the skylight 1 at the roof ridge to move upwards, thereby causing the inner sleeve rods 26 on both sides of the skylight to slide upwards within the outer sleeve 27. When the pressure relief holes 23 on the inner sleeve rods 26 are exposed, the negative wind pressure of the skylight 1 can be relieved through the pressure relief holes 23. The outer sleeve 27 is connected to the square tube 21 through elastic elements 22. When the skylight 1 moves upwards under the external negative wind pressure, the skylight 1 will cause the elastic elements 22 on both sides to stretch. After the pressure relief ends, it will reset under the action of the elastic elements 22, and when the pressure sensor 7 detects... When the negative wind pressure exceeds the pressure set by the pressure relief device, the elastic element 22 will work to move the skylight 1 upwards and release pressure through the pressure relief hole. When the negative wind pressure is lower than the pressure set by the pressure relief adjustment device 2, the skylight may have been damaged. At this time, the elastic element 22 in the pressure relief adjustment device 2 will pop up the pressure relief device by manual control and open the pressure relief hole to release pressure, ensuring that the skylight at the ridge has good load-bearing performance. It should be noted that the elastic element 22 can be a regular spring or a shock absorber. The top of the single panel 25 is fixed to the skylight 1. The single panel 25 and the skylight 1 can be fixed by bolts, pins or welding.

[0041] Reference Figure 1 The flashing 4 consists of four sets, which are installed on the four sides of the skylight 1. The top of the flashing 4 is fixed to the outer sleeve 27, and a gap is left between the bottom and the roof 5. The flashing 4 can provide a certain waterproof effect at the connection between the skylight 1 and the roof 5. At the same time, the bottom of the four sides of the skylight 1 is fixed to the roof 5 by the waterproof component 3. The waterproof component 3 can further ensure the waterproof effect at the connection between the skylight 1 and the roof 5.

[0042] Furthermore, the waterproofing component 3 includes a corrugated plate 31 and a corner splice 32. The corrugated plate 31 is located at the bottom side of the skylight 1. One end of the corrugated plate 31 is welded and fixed to the skylight 1, and the other end is welded and fixed to the roof 5. The corner splice between two adjacent corrugated plates 31 is fixed by the corner splice 32. The corner splice 32 is located at the four corners of the skylight 1. That is, the four corner splices 32 are used to connect the four side corrugated plates 31, thereby ensuring the airtightness between the entire skylight 1 and the roof 5.

[0043] Furthermore, refer to Figure 3 and Figure 4 The corrugated plate 31 includes an integrally formed skylight welding part 311, a vertical overlapping part 312, a corrugated protrusion part 313, and a roof welding part 314. The skylight welding part 311 is fixed to the bottom side of the skylight 1, and the roof welding part 314 is fixed to the roof 5. The corrugated protrusion part 313 and the roof welding part 314 are both located at both ends of the corrugated plate 31. The roof welding part 314 is used to weld the roof. The corrugated protrusion parts 313 of two adjacent corrugated plates 31 are fixed by corner splicing parts 32. The two can be fixed by bolts or welding. The two adjacent vertical overlapping parts 312 are also fixed by corner splicing parts 32. The vertical overlapping parts 312 overlap on the corner splicing parts 32. The two can also be fixed by bolts or welding. The corner splice 32 includes an upper connecting part 321 and an arc-shaped overlapping part 322. The upper connecting part 321 is located at the top of the arc-shaped overlapping part 322 and includes two vertical welding edges. The two welding edges are welded to the bottom of the corner of the skylight 1. The arc-shaped overlapping part 322 connects two adjacent pleated protrusions 313 and is fixed to the pleated protrusions 313 by welding. It should be noted that the pleated protrusions 313 have an uneven pleated structure. At the same time, the position where the arc-shaped overlapping part 322 connects to the two sides of the pleated protrusions 313 also adopts a corresponding uneven pleated structure, which matches the two sides of the pleated protrusions 313 perfectly, increasing the contact area between the two and ensuring the stability and waterproof effect when the two are welded. The bottom of the arc-shaped overlapping part 322 is welded to the roof.

[0044] Example 2 is the same as above, except that the wind-resistant and pressure-relief skylight described above can also be applied to skylights on flat roofs (such as...). Figure 6 As shown in the figure, it should be noted that the rest of the structure is the same as the structure of the wind-resistant and pressure-relief skylight at the ridge, as described above.

[0045] Example 3 is the same as above, except that the wind-resistant and pressure-relief skylight described above can be applied to skylights on sloping roofs (such as...). Figure 7 As shown), the skylight applied to the pitched roof also includes a waterproof component 2 6 located at the junction of the skylight 1 and the slope of the pitched roof (as shown). Figure 8As shown, the second waterproof component 6 is placed at the junction of the skylight 1 and the uphill section of the sloping roof. This prevents rainwater flowing from the uphill section to the downhill section from affecting the seal between the skylight 1 and the roof 5, thereby preventing the risk of roof leakage. In this setting, the second waterproof component 6 can provide initial water blocking between the skylight 1 and the roof 5, while the first waterproof component 3 between the skylight 1 and the roof provides secondary water blocking, further ensuring the seal between the skylight 1 and the roof 5.

[0046] Furthermore, refer to Figure 8 The second anti-seepage component 6 includes an anti-seepage plate 61 and an anti-seepage splicing plate 62. One end of the anti-seepage plate 61 is fixed to the side of the skylight 1 by welding or bolting, and the other end is fixed to the roof 5 through the anti-seepage splicing plate 62. The top of the anti-seepage splicing plate 62 is welded to the anti-seepage plate 61, and the bottom of the anti-seepage splicing plate 62 is welded to the roof 5. The anti-seepage plate 61 has a "C" shaped structure, with the arc-shaped opening of the "C" facing the upward slope. This installation arrangement makes it difficult for water to accumulate. The anti-seepage splicing plate 62 has an "S" shaped structure, but it can also be set to a "C" shape or other shapes, depending on the actual site conditions. Figure 8 The given structure is an "S" shape, and this application presents the "S" shape structure as the optimal implementation. An S-shaped waterproofing splice plate is installed between the C-shaped waterproofing board and the roof. Compared to right-angle connectors, the S-shaped waterproofing splice plate has a smoother transition at the joint, reducing misalignment caused by stress concentration. Rivets can also be used at the joints between the S-shaped waterproofing splice plate, the C-shaped waterproofing board, and the roof, and sealant can be used to reduce the contact area between the C-shaped waterproofing board and the roof, making the connection more secure. In addition, gaskets are installed at the connection between the S-shaped waterproof splice board and the roof. It should be noted that the gaskets here are designed in a honeycomb shape. When a connection is damaged, the honeycomb layer can ensure that the gasket has good extensibility, effectively cope with the damage and deformation at the joint, and improve the waterproof performance. The connection with the roof using rivets can effectively cope with the phenomenon that cracks are prone to occur at the connection between skylight 1 and roof 5 under temperature stress. When a connection is damaged, the honeycomb layer can ensure that the gasket has good extensibility, effectively cope with the damage and deformation at the joint, and improve the waterproof performance.

[0047] The specific operating principle of this application is as follows: When encountering rainy weather during use, when external negative wind pressure acts on the roof, different wind pressures will be generated at different locations on the roof, such as... Figure 9 This displays the wind pressure at different locations on the roof, according to... Figure 9It can be seen that the negative wind pressure is the greatest at the ridge, so the skylight 1 set at the ridge will also be subject to the greatest negative wind pressure, which will cause the skylight 1 to move upward. When the negative wind pressure is high, it may even cause the skylight 1 to break. Correspondingly, the negative wind pressure on the slope is not as great as that on the ridge, but it is still affected by the negative wind pressure. Therefore, pressure relief devices are set in the skylights at the flat roof, the sloping roof and the ridge.

[0048] When external negative wind pressure acts on the skylight 1 at the roof ridge, it will cause the skylight 1 to move upwards, thereby causing the inner sleeve rods 26 on both sides of the skylight to slide upwards within the outer sleeve 27. When the pressure relief holes 23 on the inner sleeve rods 26 are exposed, the negative wind pressure of the skylight 1 can be relieved through the pressure relief holes 23. The outer sleeve 27 is connected to the square tube 21 by elastic elements 22. When the skylight 1 moves upwards under the external negative wind pressure, the skylight 1 will cause the elastic elements 22 on both sides to stretch. After the pressure relief ends, it will reset under the action of the elastic elements 22. And when the pressure sensor 7 detects the negative wind pressure, the skylight 1 will move upwards, causing the elastic elements 22 on both sides to stretch. When the wind pressure exceeds the pressure set by the pressure relief device, the elastic element 22 will work to move the entire skylight 1 upwards and release pressure through the pressure relief hole. When the generated negative wind pressure is lower than the pressure set by the pressure relief regulating device 2, the skylight may have been damaged. At this time, the elastic element 22 in the pressure relief regulating device 2 will be manually controlled to pop up the pressure relief device and open the pressure relief hole to release pressure, ensuring that the skylight at the ridge has good load-bearing capacity. It should be noted that the elastic element 22 can be a regular spring or a shock absorber. The top of the single panel 25 is fixed to the skylight 1. The single panel 25 and the skylight 1 can be fixed by bolts, pins or welding.

[0049] The connection between the four sides of the skylight 1 and the roof 5 needs to ensure a good seal. Therefore, a waterproof component 3 is installed at the connection. The pleated plate 31 and the corner splice 32 work together to achieve a seal between the skylight 1 and the roof 5. The pleated protrusions 313 on the pleated plate 31 can obstruct rainwater when it passes through the pleated protrusions 313. The pleated protrusions 313 block the rainwater in multiple ways, thereby ensuring the seal between the skylight 1 and the roof 5. At the same time, the flashing plate 4 can withstand the impact of rainwater from above on the connection between the skylight 1 and the roof 5. When the rainwater falls on the flashing plate 4, it will be buffered by the flashing plate 4 and then slide down from the flashing plate 4 onto the roof. It should be noted that the waterproof component 3 is installed at the skylights in three locations: flat roof, pitched roof, and ridge.

[0050] On sloping surfaces, especially uphill slopes, rainwater slides down the slope from the highest ridge. Therefore, the seal between the skylight 1 and the roof 5 on the uphill slope requires further waterproofing. Thus, a waterproofing component 2 6 (such as...) is added below the flashing 4 on the uphill slope. Figure 7As shown, a second anti-seepage component 6 is added to the front end of the first anti-seepage component 3. That is, the anti-seepage board 61 and the anti-seepage splicing board 62 can block rainwater for the first time, and then the anti-seepage component 3 can block rainwater for the second time, which can further ensure the sealing effect between the skylight 1 on the upper slope and the roof 5.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
