[0139] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0140] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0141] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0142] Example

[0143] Crystalline silicon photovoltaic (PV) modules, or PV roofs, are designed to replace traditional opaque curtain walls, yet they use glass as the panel. Therefore, they combine the structural features of traditional glass curtain walls and aluminum panel curtain walls, while also meeting the technical requirements of both types of traditional curtain walls.

[0144] First, the panels used in building curtain walls or roofs can be classified into fully concealed frame, semi-concealed frame, and exposed frame types according to whether they have frames; they can be classified into closed and open types according to whether the gaps between adjacent panels are sealed; they can be classified into curtain walls (located on the building facade) and roofs according to the application scenario; and they can be classified into horizontal and vertical types according to the panel arrangement direction.

[0145] For example, in typical practices under existing technology, the subframe is fixed to the side of the glass. This necessitates matching subframes of different specifications when using exposed / concealed frame designs. Therefore, for different designs (such as fully concealed frame / fully exposed frame / horizontal exposed vertical concealed / horizontal concealed vertical exposed, etc.), four different subframe combinations will appear. Frame assembly is one of the core steps in panel assembly, and too many combinations of core steps increase the risk of errors. Furthermore, since the subframe is already bonded to the glass, removing the subframe is difficult once an error is discovered. At the same time, a large number of combination options are not conducive to building an efficient supply chain.

[0146] In the typical practice of aluminum panel curtain walls under existing technology, the horizontal and vertical arrangement of the panels corresponds to different keel forms. Using existing technology is not conducive to improving design, production, and supply chain efficiency.

[0147] It can be seen that the installation methods of the various existing technologies mentioned above have significant differences in structure.

[0148] In some existing technologies, the screw and aluminum alloy profile make point contact, and this structural form results in low safety. Other existing technologies use machine screws for fixing, which provide ideal connection strength, but require precise machining of threaded holes at the designed locations, increasing manufacturing costs. Still other existing technologies use self-tapping screws to fix panels, a practice not recognized in many countries or regions, and the threads of self-tapping screws are damaged to some extent after disassembly, thus hindering repeated disassembly and assembly and making maintenance difficult.

[0149] It is evident that several commonly used methods for fixing panels in existing technologies all have different application limitations. Furthermore, these different classifications often require different installation structures, increasing the complexity of product development, raw material procurement, and product manufacturing.

[0150] This embodiment provides a subframe with a highly versatile assembly interface structure, as well as various accessories that can be matched with the subframe. Through different combinations of parts, compatibility with the aforementioned various types of curtain wall / roof installation methods can be achieved. This will be illustrated below.

[0151] See Figure 1 This embodiment provides a panel 100. The panel 100 can be a photovoltaic panel for use in a photovoltaic curtain wall. Here, a photovoltaic panel refers to a panel 100 capable of generating photovoltaic power. A photovoltaic curtain wall refers to a curtain wall that utilizes a photovoltaic panel.

[0152] In this embodiment, the panel 100 includes a glass assembly 10 and a frame 11. The glass assembly 10 is connected to the frame 11. The glass assembly 10 can be a double-glass assembly, which is a solar-powered assembly composed of two pieces of glass, several solar cells, a power-connecting structure 12, and multiple layers of encapsulant film. The power-connecting structure 12 can be used to conduct the electricity generated by the photovoltaic cells for storage or use.

[0153] In this embodiment, the frame 11 includes four sub-frames 13, which are connected end to end in the circumferential direction to form a rectangle. The sub-frames 13 (or glass sub-frames) are assembled on the edge of the glass assembly 10, providing support for the glass assembly 10 and providing an installation interface for assembling the glass assembly 10.

[0154] See Figure 2 and Figure 3 In some embodiments, the frame 11 further includes a reinforcing frame 14, which is connected between two opposing subframes 13. The reinforcing frame 14 serves to strengthen the structural strength of the frame 14 and can support the glass assembly 10. The number of reinforcing frames 14 can be one or more, for example... Figure 2 There is one reinforced box 14 in the middle. Figure 3 There are two reinforcing boxes in section 14.

[0155] In this embodiment, Figure 1 , Figure 2 and Figure 3 Panels 100 in three sizes—small, medium, and large—are shown respectively.

[0156] See Figure 4 In this embodiment, adjacent subframes 13 are perpendicular to each other and are fastened together by self-tapping screws 15.

[0157] See Figure 5 In this embodiment, the reinforcing frame 14 and the subframe 13 are also fastened together by self-tapping screws 15.

[0158] Figure 6 and Figure 7 Two different appendices 13 are shown. For easy distinction, Figure 6 and Figure 7 The sub-frames 13 in the text are labeled as sub-frame 13a and sub-frame 13b, respectively.

[0159] See Figure 6 The subframe 13a includes a bottom wall 16, a first side wall 17, and a second side wall 18. The first side wall 17 and the second side wall 18 are respectively connected to the two sides of the bottom wall 16, and the first side wall 17 and the second side wall 18 are spaced apart and opposite each other. Thus, the subframe 13a has a roughly U-shaped cross-section along its length direction, and the inner space 19 enclosed by it can be used to accommodate structures such as cables for photovoltaic panels.

[0160] The first sidewall 17 has a first interface structure 20 protruding from its surface facing the second sidewall 18. The first interface structure 20 includes two snap-fit ​​portions 21, which are spaced apart along a direction perpendicular to the bottom wall 16. Each snap-fit ​​portion 21 is hook-shaped and bent towards the bottom wall 16. Specifically, each snap-fit ​​portion 21 includes a first folded edge 22 and a second folded edge 23. The first folded edge 22 extends vertically from the inner surface of the first sidewall 17, and the second folded edge 23 bends from the end of the first folded edge 22 away from the first sidewall 17 towards the bottom wall 16, so that the first folded edge 22 and the second folded edge 23 are connected to form an L-shape.

[0161] In this embodiment, the first folded edge 22 of one snap-fit ​​portion 21 facing away from the bottom wall 16 is connected to the end point of the first side wall 17 facing away from the bottom wall 16. The other snap-fit ​​portion 21 can be connected at 1 / 2 height of the bottom wall 16.

[0162] In this embodiment, a second interface structure 24 is provided at the end of the second sidewall 18 away from the bottom wall 16. The second interface structure 24 includes an end wall 25 perpendicular to the second sidewall 18, and the end wall 25 and the second sidewall 18 are combined to form a T-shape. The end wall 25 may be parallel to the bottom wall 16, and both sides of the end wall 25 extend out of the second sidewall 18 respectively.

[0163] In this embodiment, both the outer cover 34 and the glass support plate 44 are provided with a third interface structure 38 adapted to the first interface structure 20 (visible in...). Figure 12 or Figure 14 ), which will be described in detail below.

[0164] See Figure 7 In addition to the subframe 13a, the subframe 13b is further provided with a threaded sleeve 26. The threaded sleeve 26 protrudes from the inner surface of the bottom wall 16. The number of threaded sleeves 26 can be one or more, for example... Figure 7 Two of them.

[0165] exist Figures 1-3 In the frame 11 shown, one set of subframes 13 adopts Figure 6 The attached frame 13a shown, another set of attached frames 13 adopts Figure 7 Subframe 13b is shown. A self-tapping screw 15 passes through between the two connected subframes 13. Figure 6 The bottom wall 16 of the attached frame 13a shown is threaded to... Figure 7 The threaded sleeve 26 of the subframe 13b shown enables the connection between adjacent subframes 13.

[0166] Of course, in other embodiments, each of the subframes 13 of the frame 11 may adopt... Figure 6 Subframe 13a or both adopt Figure 7 Appendix 13b.

[0167] Figure 8 The reinforcing frame 14 of this embodiment is shown.

[0168] See Figure 8 In this embodiment, the reinforcing frame 14 includes an outer frame 27 and a threaded sleeve 26a. The outer frame 27 is rectangular, and the threaded sleeve 26a is connected to the inner side of the outer frame 27. The reinforcing frame 14 can have one or two threaded sleeves 26a.

[0169] exist Figures 1-3 In the frame 11 shown, between the connected subframe 13 and reinforcing frame 14, self-tapping screws 15 pass through the bottom wall 16 of the subframe 13 and are threaded together. Figure 8 The threaded sleeve 26a of the reinforcing frame 14 shown enables the connection between the subframe 13 and the reinforcing frame 14.

[0170] In this embodiment, both the subframe 13 and the reinforcing frame 14 can be made of aluminum alloy profiles. The ends of the subframe 13 and the reinforcing frame 14 that make up the frame 11 do not require chamfering. The subframes 13 and 14 are assembled perpendicularly to each other and to each other, without the need for corner brackets; they are connected solely by self-tapping screws 15. This assembly structure facilitates processing and ensures the quality of the parts at the joints.

[0171] See Figure 9 or Figure 10 In the panel 100 of this embodiment, the glass assembly 10 and the subframe 13 are bonded together by an adhesive structure 28. Specifically, the glass assembly 10 is bonded and fixed to the surface of the first sidewall 17 of the subframe 13 away from the second sidewall 18 by the adhesive structure 28.

[0172] The adhesive structure 28 may include sealant 29 and double-sided adhesive 30. For example, sealant 29 is disposed on the side away from the bottom wall 16, and double-sided adhesive 30 is disposed on the side close to the bottom wall 16. As a spacer material, double-sided adhesive 30 has excellent air permeability, which is beneficial to the curing of sealant 29 (such as silicone structural sealant).

[0173] In this embodiment, a connecting groove 31 is recessed on the outer side of the second sidewall 18 of the subframe 13 (also seen in...). Figure 6 or Figure 7 The connecting groove 31 is located at one end of the second sidewall 18 near the bottom wall 16. In this embodiment, the outer surface of the second sidewall 18 can be fitted with a sealing strip 32, and one end of the sealing strip 32 can be snapped into the connecting groove 31 to achieve connection with the second sidewall 18.

[0174] Optionally, the connecting groove 31 can be configured as a groove with a smaller and narrower opening and a wider interior (such as a T-shape, dovetail shape, etc.) to prevent the sealing strip 32 from detaching from the second side wall 18. The interface (i.e., the connecting groove 31) of the subframe 13 for installing the sealing strip 32 is a press-fit interface, and the sealing strip 32 can be elastically pressed into the connecting groove 31 to achieve assembly with the subframe 13.

[0175] Sealing strip 32 can be used to seal and fill the second sidewall 18 and the outer structure (such as base 50, see...) Figure 19 The gap between them. Optionally, the surface of the sealing strip 32 facing away from the second sidewall 18 can be a toothed surface 33.

[0176] See Figure 11 In this embodiment, the glass assembly 10 and the reinforcing frame 14 are bonded together by an adhesive structure 28a. Specifically, the glass assembly 10 is bonded and fixed to the surface of the reinforcing frame 14 near the glass assembly 10 by the adhesive structure 28a.

[0177] The adhesive structure 28a may include sealant 29 and double-sided adhesive 30. For example, sealant 29 is provided on both sides of the adhesive structure 28a, and double-sided adhesive 30 is provided in the middle. The double-sided adhesive 30 serves as a spacer material and has excellent air permeability, which is beneficial for the curing of sealant 29 (such as silicone structural sealant).

[0178] See Figure 12 and Figure 13 In some embodiments, the panel 100 also includes an outer cover 34. The outer cover 34 is used to protect and decorate the sides of the glass assembly 10.

[0179] The outer cover 34 includes a third wall 35, a fourth wall 36, and a fifth wall 37. The third wall 35, the fourth wall 36, and the fifth wall 37 are connected in sequence to form a U-shape.

[0180] A third interface structure 38 is protruding from the inner surface of the third wall 35. The third interface structure 38 includes two mating hooks 39, which are spaced apart along a direction perpendicular to the fourth wall 36. The mating hooks 39 are hook-shaped and bent toward the fourth wall 36.

[0181] The U-shaped outer cover 34 is fitted over the outside of the glass assembly 10 and the first sidewall 17, serving to protect the sides of the glass assembly 10. The glass assembly 10 and the first sidewall 17 extend between the third wall 35 and the fifth wall 37. The first sidewall 17 and the third wall 35 are parallel and engage with the latch 39 at the latching part 21 to achieve a latching engagement between the outer cover 34 and the subframe 13.

[0182] A joint filler structure 40 is fitted between the fifth wall 37 and the outer surface of the glass assembly 10. Optionally, the joint filler structure 40 includes a pad 41, a foam rod 42, and a sealant 29 (such as silicone architectural sealant). The joint filler structure 40 can support the glass assembly 10 to the fifth wall 37 along the thickness direction using the pad 41, and achieve a sealed connection between the fifth wall 37 and the glass assembly 10 using the sealant 29. The foam rod 42 can be inserted into the gap before the sealant 29 is applied to facilitate the injection of the sealant 29.

[0183] In this embodiment, optionally, the fourth wall 36 is threaded with a set screw 43. The end of the set screw 43 abuts against the first side wall 17, for engaging the locking hook 39 of the third interface structure 38 with the locking portion 21 of the first interface structure 20.

[0184] In this embodiment, the set screw 43 is threaded into the threaded hole on the fourth wall 36 of the outer cover 34 and abuts against the first folded edge 22 of the snap-fit ​​portion 21 at the outer end of the first side wall 17 of the subframe 13 (e.g., Figure 12 By tightening the set screw 43, the snap-fit ​​part 21 can be reliably engaged with the matching hook 39 without disengaging.

[0185] In some embodiments, the spacing between the set screws 43 along the length of the outer cover 34 is no greater than 450 mm. The number and position of the pads 41 can be consistent with the set screws 43, thereby ensuring that the outer cover 34 is securely assembled.

[0186] See Figures 14-16 In some embodiments, the panel 100 does not have an outer cover 34, but has a glass support plate 44. The glass support plate 44 includes a first wall 45 and a second wall 46, which intersect perpendicularly to form an L-shape.

[0187] A third interface structure 38 is protruding from the inner surface of the first wall 45. The third interface structure 38 includes two mating hooks 39, which are spaced apart along a direction perpendicular to the second wall 46. The mating hooks 39 are hook-shaped and bent toward the second wall 46.

[0188] Both the first sidewall 17 and the first wall 45 are vertical. The glass support plate 44 is suspended on the locking part 21 by engaging the hook 39, and the second wall 46 extends horizontally to the bottom of the glass assembly 10 and supports the glass assembly 10.

[0189] Optionally, the panel 100 also includes a pad 41, which is placed between the second wall 46 of the glass support plate 44 and the glass assembly 10 to achieve a cushioning and protective effect. Optionally, a foam rod 42 and sealant 29 may also be provided between the second wall 46 and the glass assembly 10 to achieve filling and sealing adhesion.

[0190] In this way, the weight of the glass assembly 10 can be borne by the glass support plate 44 and transferred to the subframe 13 through the matching hook 39, which can prevent the weight load of the glass assembly 10 from being applied to the adhesive structure 28 between the subframe 13 and the glass assembly 10 for a long time, thus preventing the adhesive structure 28 from aging.

[0191] See Figure 16 In this embodiment, the glass support plate 44 can be a multi-segment structure broken along the length of the glass assembly 10. For example, Figure 16 The glass tray 44 includes two segments that are broken along the length direction, or in other words, the glass tray 44 includes two segments spaced apart along the length direction.

[0192] Figure 15 and Figure 16 The structure shown is applicable to the design of glass support plate 44 for enclosed curtain walls. When the curtain wall / roof structure adopts an enclosed design, the glass support plate 44 can be made into a 100mm long part, together with the pad 41, according to... Figure 16 The positions shown are fitted on the left and right sides of the bottom edge of panel 100 and fixed in the designed position with sealant 29 (such as silicone building sealant).

[0193] Figure 17 and Figure 18 The structure shown is applicable to the glass support plate 44 design for open curtain walls.

[0194] See Figure 17 and Figure 18 In this embodiment, the glass support plate 44 can also be a continuous structure along the length of the glass assembly 10 to provide more reliable support. When the curtain wall / roof structure adopts an open design, see [reference needed]. Figure 18 The glass support plate 44 can be arranged along the bottom edge of the panel 100, and two pads 41 are arranged at designated positions to support the glass assembly 10. Foam rods 42 can be installed in the gap between the glass support plate 44 and the glass assembly 10, and sealant 29 (such as silicone building sealant) can be injected.

[0195] Thus, the subframe 13 in this embodiment can be adapted to glass support plates 44 of different lengths, thereby making it suitable for different application scenarios (such as open curtain walls or closed curtain walls).

[0196] As described above, the first interface structure 20 of the subframe 13 can be adapted to the third interface structure 38 of the glass support plate 44, and can be adapted to glass support plates 44 of different lengths. Furthermore, the first interface structure 20 of the subframe 13 can also be adapted to the third interface structure 38 of the outer cover 34. Thus, the subframe 13 in this embodiment has high versatility and can be applied to different installation scenarios.

[0197] This embodiment also provides a photovoltaic curtain wall 200, which uses the aforementioned panel 100 with photovoltaic power generation function, thereby achieving energy saving and environmental protection.

[0198] See Figures 19-21 In this embodiment, the photovoltaic curtain wall 200 includes a base 50, a panel support block 51, and a plurality of the aforementioned panels 100. The base 50 is used for fixed connection to the keel 52. The panel support block 51 is connected to the base 50, and the panels 100 are supported on the panel support block 51.

[0199] The keel 52 can be the basic structure of the building where the photovoltaic curtain wall 200 is located, used for installing the panel 100. The keel 52 can include vertical keels along the vertical direction and horizontal keels along the horizontal direction. The horizontal keels and vertical keels are connected to form a crisscrossing grid structure for fixing and installing the panel 100.

[0200] See also Figure 19 In this embodiment, the base 50 includes a sixth wall 53, a seventh wall 54, and an eighth wall 55, which are connected sequentially to form a U-shape. The outer surfaces of the sixth wall 53 and the eighth wall 55 are respectively configured with toothed surfaces 33a (see...). Figure 22 The sixth wall 53 and the eighth wall 55 are sandwiched on both sides of the keel 52 and are fixedly connected to the keel 52 (also seen in...). Figure 23 and Figure 24 The seventh wall 54 is located outside the keel 52.

[0201] The seventh wall 54 has a U-shaped connecting wall 56 formed by an inward indentation at the middle position in the width direction (also seen in...). Figure 22 The inner side of the connecting wall 56 defines the receiving groove 57.

[0202] The photovoltaic curtain wall 200 also includes an adapter 58, which snaps into the receiving groove 57. The adapter 58 can also be found in [reference needed]. Figure 25 .

[0203] The panel support block 51 is fastened to the adapter 58 by the locking member 59 and supports the panel 100.

[0204] In this embodiment, a dedicated mounting interface (i.e., the connecting wall 56 forming the receiving groove 57) is designed on the base 50 to accommodate the adapter 58. Threaded holes are machined on the adapter 58, and screws are fastened to the adapter 58, thus solving the problem of low security of bolts and self-tapping screws in the prior art. Furthermore, since the adapter 58 can slide within the groove, its position can be adjusted on-site as needed, eliminating the need to machine threaded holes when machining the base 50, thus simplifying the machining process.

[0205] It should be noted that, Figures 19-21The keel 52 is a vertical keel, and the length direction of the base 50 is parallel to the vertical direction G. The panel support block 51 is the first panel support block 51a, which includes a ninth wall 64 and a tenth wall 65, which are vertically connected in an L-shape. The ninth wall 64 is attached to and connected to the adapter 58 by a locking member 59. The tenth wall 65 is connected to the upper end of the ninth wall 64 and supports the panel 100. The upper surface of the first panel support block 51a is at the same elevation as the bottom edge of the glass assembly 10.

[0206] Optionally, the locking element 59 includes two self-tapping screws 15 and one hex pan head screw 60.

[0207] Optionally, a sealing strip 32, superimposed on the outer side of the second side wall 18 of the subframe 13, seals the space between the second side wall 18 and the seventh wall 54 of the base 50. The sealing strip 29 provides a cushioning effect and reduces noise generation.

[0208] For standard curtain wall / roof structures, panel 100 can be assembled by fixing only one set of opposite edges. Depending on the facade panel design, base 50 only needs to be placed on one of the horizontal or vertical main keels.

[0209] Figures 26-27 In the design, the keel 52 is a transverse keel along the horizontal direction, and the width direction of the base 50 is parallel to the vertical direction G. The panel support block 51 is a second panel support block 51b. The second panel support block 51b includes a rectangular frame 66 and an extension wall 67. The rectangular frame 66 is attached to and connected to the adapter 58 by a locking member 59a. Optionally, the locking member 59a includes an internal hex pan head screw, a flat washer, and a spring washer.

[0210] The extension wall 67 protrudes from the upper surface of the rectangular frame 66 and is spaced from the seventh wall 54 of the base 50 to define the clamping space 68. The second interface structure 24 of the second sidewall 18 includes an end wall 25 perpendicular to the second sidewall 18, and the end wall 25 and the second sidewall 18 are combined to form a T-shape. The end wall 25 of the second interface structure 24 of the downward-facing subframe 13 of the panel 100 is supported on the rectangular frame 66 and sandwiched between the extension wall 67 and the seventh wall 54.

[0211] Optionally, a sealing strip 32 superimposed on the outer side of the second side wall 18 of the subframe 13 is sealed between the second side wall 18 and the seventh wall 54 of the base 50.

[0212] See Figure 26 There can be multiple second panel support blocks 51b, which are arranged at intervals along the length of the base 50 to jointly support the panel 100.

[0213] Figure 28 Show structure and Figure 27 They are basically the same, the difference is that... Figure 27 The second panel support block 51b (see) is used Figure 29 )and Figure 28 The second panel support block 51b (see) is used Figure 30 The different lengths of the rectangular frames 66 are mainly reflected in their different lengths. Thus, by using the second panel support blocks 51b of different sizes, the panel 100 can be supported at different heights (i.e., the center elevation of the crossbeam) of the relatively horizontal keel.

[0214] In this embodiment, a base 50 is fitted onto the keel 52, providing an interface for the assembly of the panel 100. Controlling the adjustment gap between the keel 52 and the base 50 within a suitable range can accommodate reasonable deviations during the production and installation of the keel 52 without causing excessive adverse effects on the connection structure. Optionally, the inner net width of the base 50 is 85mm, and the width of the keel 52 is preferably 60-70mm, as can be seen in [the following text is missing from the original extract]. Figures 22-24 .

[0215] See you again Figures 22-24 In this embodiment, the base 50 is assembled onto the keel 52 via a bolt assembly 61 (including bolts, flat washers, spring washers, and hexagonal nuts), a toothed plate 62, and an adjusting shim 63. The toothed plate 62 and the adjusting shim 63 eliminate reasonable tolerances caused by the machining and installation of the keel 52. The base 50 is designed with a dedicated interface for assembling the panel 100 (i.e., the connecting wall 56 forming the receiving groove 57), which ensures the reliability of the panel 100 assembly.

[0216] Depending on the length of the base 50, each base 50 is connected to the keel 52 by a fixed bolt assembly 61 and at least one sliding bolt assembly 61. The spacing of the bolt assemblies 61 should be determined according to the actual load, and the distance between the first and last bolt assemblies 61 and the end of the base 50 should not exceed 250mm.

[0217] See Figures 31-34 The photovoltaic curtain wall 200 also includes a pressing block 69.

[0218] The pressure block 69 includes an eleventh wall 70, two twelfth walls 71, and two thirteenth walls 72. The two twelfth walls 71 are perpendicularly connected to the two sides of the eleventh wall 70 in the width direction, and the two thirteenth walls 72 are perpendicularly connected to the eleventh wall 70 and are spaced apart between the two twelfth walls 71. The seventh wall 54 of the base 50 is recessed with limiting grooves 73 on both sides of the receiving groove 57.

[0219] The portions of the seventh wall 54 of the base 50 located on either side of the receiving groove 57 respectively support the second sidewall 18 of the subframe 13 of a panel 100. A locking member 59b passes through the eleventh wall 70 from between the two thirteenth walls 72 and locks the pressure block 69 to the adapter 58. Optionally, the locking member 59b includes an internal hex pan head screw, a flat washer, and a spring washer.

[0220] Furthermore, the inward-facing end of the end wall 25 on the second side wall 18 of the subframe 13 is positioned between the twelfth wall 71 and the thirteenth wall 72. The thirteenth wall 72 extends into and engages with the limiting groove 73 to mutually limit the position of the base 50. In this way, when the panel 100 deforms, the subframe 13 and the pressure block 69 can hook onto each other, preventing the subframe 13 from slipping off.

[0221] Optionally, the spacing between the twelfth wall 71 and the thirteenth wall 72 is greater than the thickness of the end wall 25, so that the end wall 25 can be adjusted in position between the twelfth wall 71 and the thirteenth wall 72. In this way, the spacing between adjacent subframes 13 can be adjusted within a certain range to accommodate curtain wall structures with different panel 100 spacings.

[0222] For curtain walls with varying spacing between adjacent panels 100, different sized pressure blocks 69 are used for adaptation. For example, Figure 32 The spacing between adjacent panels 100 in the middle is greater than Figure 31 ,but Figure 32 use Figure 34 The larger pressure block 69 shown is... Figure 31 use Figure 33 The smaller pressure block 69 is shown.

[0223] See also Figures 35-38 In this embodiment, there are multiple pressure blocks 69, which are distributed on a set of opposing subframes 13 of the panel 100. Optionally, the spacing between adjacent pressure blocks 69 can be set within a certain range, for example, 200-400mm (300mm is a practical option). Optionally, the distance between the first and last pressure blocks 69 and the end of the panel 100 is set to no more than 150mm. This ensures that the pressure blocks 69 have a high clamping force.

[0224] For example, Figure 35 and Figure 36 The small panel 100 shown (e.g.) Figure 1 The pressure block 69 can be distributed on the subframe 13 on a set of long sides of the panel 100, or on the subframe 13 on a set of short sides of the panel 100. Figure 37 The medium-sized panel 100 shown (e.g.) Figure 2 )as well as Figure 38 The large panel 100 shown (e.g.) Figure 3The pressure blocks 69 can be distributed on the subframes 13 at both ends of the reinforcing frame 14 along the length of the panel 100.

[0225] As described above, through the arrangement of the first interface structure 20 and the second interface structure 24 of the subframe 13, the panel 100 of this embodiment can be fitted with two different sizes of pressure blocks 69. Figure 33 , Figure 34 ), and the vertically placed panel 100 can be used with the first panel support block 51a ( Figure 19 ), Horizontal panel 100 uses second panel support block 51b ( Figure 29 and Figure 30 This allows for different functions, making it suitable for various installation requirements.

[0226] See Figure 39 and Figure 40 In this embodiment, among the multiple panels 100 of the photovoltaic curtain wall 200, the installation gaps between adjacent panels 100 are filled with a sealing structure 74. The sealing structure 74 may include foam rods and sealant (such as silicone building sealant).

[0227] in, Figure 39 The photovoltaic curtain wall 200 uses Figure 15 and Figure 17 The panel 100 shown has a glass support plate 44. Figure 40 The photovoltaic curtain wall 200 uses Figure 12 The panel 100 shown has an outer cover 34.

[0228] Figure 39 and Figure 40 The diagram shows a closed-off curtain wall or roof, where the gaps between adjacent panels 100 are sealed by a sealing structure 74.

[0229] In other embodiments, the gaps between adjacent panels 100 may remain open without filling the sealing structure 74. That is, the panel 100 of this embodiment can also be applied to open curtain walls or roofs. In this case, a separate waterproof structure can be designed on the back side of the panel 100, taking into account the weather resistance of the relevant components.

[0230] In summary, the appendix 13 provided in this application embodiment, through its interface structure design, can be adapted to a variety of different installation scenarios, has strong versatility, and saves design and development costs.

[0231] In addition to being used for curtain walls and roofs, the structure of this embodiment can also be used for photovoltaic or non-photovoltaic building panels 100, including but not limited to building skylights, railings, and canopies.

[0232] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
