Description

Technical Field

[0001] This application relates to the field of border connection technology, and more specifically, to a border component. Background Technology

[0002] Currently, photovoltaic frames are mainly made of aluminum alloy profiles, and their assembly is primarily achieved through mounting with aluminum alloy corner brackets and pinholes for positioning. However, as a high-carbon emission material, aluminum alloy will limit its further development in terms of production capacity and carbon footprint verification.

[0003] Fiber-reinforced composite materials, as a new type of material that is lightweight, high-strength, and highly designable, have significant advantages in terms of performance and carbon emissions, and are already being used on a large scale in photovoltaic encapsulation. However, composite materials are fiber-reinforced resins, which cannot be fixed to corner brackets and form stable frames using methods similar to the plastic pressing of aluminum alloys.

[0004] For fiber-reinforced resin material frames, the current encapsulation method involves needle-punching adhesive onto the inner side of the frame to create adhesive bumps for diagonal positioning. However, this method is prone to failure because not all adhesive points can bear force simultaneously, leading to damage to the encapsulation structure. Utility Model Content

[0005] In view of the above-mentioned shortcomings, this application provides a border component to improve the problem of low connection strength of border components in related technologies.

[0006] This application is implemented as follows:

[0007] In a first aspect, an example of this application provides a frame assembly including a first frame strip, a second frame strip, and a corner bracket. The corner bracket has a first connector and a second connector connected at a predetermined angle; the first connector includes a first connecting sleeve and a first connecting arm, the first connecting sleeve being bonded to the inner wall of the end of the first frame strip by a first fiber resin adhesive layer; the interior of the first connecting sleeve is provided with a first channel and a first opening communicating with the first channel, and a first mating member is provided at the circumferential edge of the first connecting sleeve; the first connecting arm is provided with a second mating member for inserting through the first opening into the first channel and engaging with the first mating member; the second connector is bonded to the inner wall of the end of the second frame strip by a second fiber resin adhesive layer.

[0008] In the above implementation process, the second connector of the corner bracket is bonded to the inner wall of the end of the second frame strip through the second fiber resin layer, and a first connecting arm of the first connecting sleeve that can be interlocked with each other is provided in the first connector of the corner bracket. The first connecting sleeve is bonded to the inner wall of the end of the first frame strip through the first fiber resin adhesive layer. Therefore, when assembling the frame assembly on site, the operator only needs to insert the second mating part of the first connecting arm through the first opening of the first connecting sleeve into the first channel and snap it with the first mating part. On-site adhesive application is not required. The embodiments of this application bond the corresponding frame strip and connector through the first and second fiber resin adhesive layers, which eliminates the need to drill holes in the frame strip. It is applicable to the connection of frame strips made of fiber resin materials and other materials that are not easy to drill holes in, and has high adaptability. Moreover, the combination of fiber fabric and resin adhesive in the fiber resin adhesive layer not only improves the strength of the fiber resin adhesive layer itself, but also improves the bonding strength between the fiber resin adhesive layer and the inner wall of the frame strip and the outer wall of the first connecting sleeve / second connector, thereby improving the overall strength of the assembled frame structure.

[0009] In conjunction with the first aspect, in an optional embodiment of this application, the second connector includes a second connecting arm, which is bonded to the inner wall of the end of the second frame strip by a second fiber resin adhesive layer.

[0010] In the above implementation process, the second connecting arm is directly bonded to the inner wall of the end of the second frame strip through the second fiber resin adhesive layer. Under the premise of ensuring the connection strength and connection convenience of the frame assembly, a connecting sleeve can be omitted in the second frame strip. In the entire connection structure of the first frame strip and the second frame strip, only one first connecting sleeve is set on the inner wall of the end of the second frame strip, which can save production costs.

[0011] In conjunction with the first aspect, in an optional embodiment of this application, the second connector includes a second connecting sleeve and a second connecting arm. The second connecting sleeve is bonded to the inner wall of the end of the second frame strip by a second fiber resin adhesive layer. The interior of the second connecting sleeve is provided with a second channel and a second opening communicating with the second channel. A third mating member is provided at the circumferential edge of the second connecting sleeve. The second connecting arm is provided with a fourth mating member for inserting through the second opening into the second channel and engaging with the third mating member.

[0012] In the above implementation process, connecting sleeves are bonded to the inner walls of both the first and second frame strip ends using a fiber resin adhesive layer. When assembling the frame assembly, the operator can insert the second mating component at the first connecting arm of the corner bracket through the first opening of the first connecting sleeve into the first channel and engage it with the first mating component. Similarly, the operator can insert the fourth mating component at the second connecting arm of the corner bracket through the second opening of the second connecting sleeve into the second channel and engage it with the third mating component. During frame assembly, no on-site adhesive application or opening of the frame strips is required. Furthermore, if some frame strips are found to be substandard due to transportation or other reasons and need to be discarded, the discarded frame strips are not bonded to the main structure of the corner bracket, such as the connecting arms, thus saving on corner bracket production costs to a certain extent.

[0013] In conjunction with the first aspect, in an optional embodiment of this application, the first mating member includes a third opening disposed on the side wall of the first connecting sleeve, the third opening communicating with the first channel; the second mating member includes a boss protruding from the end of the first connecting arm; when the first connecting arm is connected to the first connecting sleeve, the boss retracts, passes through the first opening into the first channel to the position of the third opening, and then the boss springs back and engages with the third opening.

[0014] In the above implementation process, a third opening communicating with the first channel is provided on the side wall of the first connecting sleeve, and a boss is provided at the end of the first connecting arm. When it is necessary to assemble the frame assembly, pressure can be applied to the boss of the first connecting arm to cause the boss to retract and extend into the first channel from the first opening. The boss is kept in a retracted state by the pressure of the side wall of the connecting sleeve. When the boss moves to the third opening on the side wall, the pressure applied to the boss by the first connecting sleeve disappears, and the boss can spring back and lock into the third opening.

[0015] In conjunction with the first aspect, in an optional embodiment of this application, the first connecting sleeve is provided with a third opening on both opposite sidewalls, and the end of the first connecting arm is provided with two oppositely arranged bosses, which are used to engage with the two third openings in a one-to-one correspondence.

[0016] In the above implementation process, a third opening-shaped first mating part is provided on each of the two opposite side walls of the first connecting sleeve, and two opposite bosses are provided at the end of the first connecting arm. When assembling the frame assembly, the two bosses at the end of the first connecting arm can be engaged with the two third openings of the first connecting sleeve one by one, thereby further improving the connection stability.

[0017] In conjunction with the first aspect, in an optional embodiment of this application, the first connecting sleeve is a through-groove structure or a hollow tubular structure. Along the axial direction of the first connecting sleeve, the third opening is located in the middle of one of the side walls of the first connecting sleeve.

[0018] In conjunction with the first aspect, in an optional embodiment of this application, the first connecting arm is hollowed out. When the first connecting arm is connected to the first connecting sleeve, the boss can retract toward the hollowed-out area. After the boss passes through the first opening into the first channel to the position of the third opening, the boss springs back and engages with the third opening.

[0019] In the above implementation process, the first connecting arm is designed with a hollow shape. Pressure can be applied to the hollow first connecting arm, causing it to deform and causing the boss at the first connecting arm to contract towards the hollow area, allowing the boss to extend into the first channel of the first connecting sleeve. Before the boss moves to the third opening, the side wall of the first connecting sleeve continuously applies pressure to the boss, keeping it in a contracted state. When the boss moves to the third opening at the side wall, the pressure applied by the first connecting sleeve to the boss disappears, and the compressed connecting arm can spring back, allowing the boss to be locked at the third opening.

[0020] In conjunction with the first aspect, in an optional embodiment of this application, the end of the first connecting arm away from the second connecting member is a pointed structure, and the connection between the pointed structure and the middle part of the first connecting arm forms a stepped boss.

[0021] In the above implementation process, a pointed structure is provided at the end of the first connecting arm, which facilitates the pointed structure to pass through the first opening of the first connecting sleeve into the first channel. The side wall of the first connecting sleeve gradually applies pressure to the pointed structure, causing the first connecting arm to retract. When the boss at the pointed structure moves to the third opening, it can spring back and engage with the third opening.

[0022] In conjunction with the first aspect, in an optional embodiment of this application, the first connecting arm and the second connecting member are at 90°. The end face of the first frame bar near the second frame bar is a first inclined surface, and the end face of the second frame bar near the first frame bar is a second inclined surface. The inclination angles of the first inclined surface and the inclination angles of the second inclined surface are complementary.

[0023] In the above implementation process, the end faces of the first frame strip and the second frame strip are set as complementary bevels. After connecting the first frame strip and the second frame strip with corner brackets, a right-angle frame structure can be formed, which can meet the packaging requirements of photovoltaic modules and other devices with right-angle structures.

[0024] In conjunction with the first aspect, in an optional embodiment of this application, the frame assembly includes two sets of first frame strips and second frame strips, which are connected end to end in sequence by corner brackets, a first fiber resin adhesive layer, and a second fiber resin adhesive layer.

[0025] In the above implementation process, the two sets of first frame strips and second frame strips are connected end to end in sequence through the corner code and fiber resin adhesive layer of the present application embodiment to form an enclosed frame structure to meet the encapsulation requirements of structures such as photovoltaic modules.

Detailed Implementation

[0032] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms “comprising” and “having”, and any variations thereof, in the specification and the foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0034] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] Currently, photovoltaic frames are mainly made of aluminum alloy profiles, and their assembly method primarily involves mounting using aluminum alloy corner brackets with indented holes. For example, one end of the corner bracket is inserted into the frame strip, and then the corner bracket and frame strip are stamped together. During the forming process, the frame and corner bracket are processed and stamped together, and the indentations formed on the frame coincide with the deformed parts on the corner bracket, thus fixing one end of the corner bracket to the frame.

[0037] Fiber-reinforced composite materials, as a new type of material that is lightweight, high-strength, and highly designable, have begun to be used on a large scale in photovoltaic encapsulation. However, since composite materials are fiber-reinforced resins, they cannot be fixed with corner brackets and form a stable frame using a method similar to the plastic pressing of aluminum alloys.

[0038] For fiber-reinforced resin material frames, the current encapsulation method involves needle-punching adhesive onto the inner side of the frame to create adhesive bumps for diagonal positioning. However, this method is prone to failure because not all adhesive points can bear force simultaneously, leading to damage to the encapsulation structure.

[0039] Therefore, this application further improves the border component, thereby improving the assembly problem of the border component to a certain extent. To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0040] Please see Figure 1 This application provides a border component 1, which includes a first frame strip 10, a second frame strip 20, and a corner code 30.

[0041] In this regard, please combine Figure 1 and Figure 2The corner bracket 30 has a first connector 31 and a second connector 32 connected at a preset angle. The first connector 31 includes a first connecting sleeve 311 and a first connecting arm 312. The first connecting sleeve 311 is bonded to the inner wall of the end of the first frame strip 10 by a first fiber resin adhesive layer 33. The interior of the first connecting sleeve 311 is provided with a first channel 3111 and a first opening 3112 communicating with the first channel 3111. A first mating part 3113 is provided at the circumferential edge of the first connecting sleeve 311. The first connecting arm 312 is provided with a second mating part 3121, which is used to pass through the first opening 3112 into the first channel 3111 and engage with the first mating part 3113. The second connector 32 is bonded to the inner wall of the end of the second frame strip 20 by a second fiber resin adhesive layer 34.

[0042] When assembling the frame assembly 1 provided in this embodiment on-site, the operator only needs to insert the second mating part 3121 at the first connecting arm 312 through the first opening 3112 of the first connecting sleeve 3111 into the first channel 3111 and snap it into the first mating part 3113. On-site adhesive application is not required. This embodiment uses the first fiber resin adhesive layer 33 and the second fiber resin adhesive layer 34 to bond the corresponding connecting sleeve and connecting part, eliminating the need for drilling holes in the frame strip. This makes it suitable for connecting frame strips made of fiber resin materials that are difficult to drill holes in, offering high adaptability. Furthermore, the combination of the fiber fabric and resin adhesive in the fiber resin adhesive layer not only improves the strength of the fiber resin adhesive layer itself but also enhances the bonding strength between the fiber resin adhesive layer and the inner wall of the frame strip and the outer wall of the first connecting sleeve 311 / second connecting part 32, thereby improving the overall strength of the frame assembly 1.

[0043] It is understood that the border component 1 provided in this application embodiment has at least two states, including as follows: Figure 1 The first state shown: The second mating member 3121 of the first connecting arm 312 does not pass through the first opening 3112 into the first channel 3111 and engage with the first mating member 3113. This includes, for example... Figure 4 The second state shown: The second mating part 3121 of the first connecting arm 312 has passed through the first opening 3112 into the first channel 3111 and engaged with the first mating part 3113.

[0044] It is understood that the first frame strip 10 and the second frame strip 20 are hollow profiles. This application does not limit the specific structure and material of the first frame strip 10 and the second frame strip 20, and appropriate selections can be made according to conventional frame strip structures and materials in the art.

[0045] As an example, the first frame strip 10 and the second frame strip 20 can be made of metal or composite materials. Metals include, but are not limited to, aluminum or aluminum alloys. Composite materials include, but are not limited to, fiber-reinforced resin materials such as glass fiber reinforced resin materials and carbon fiber resin reinforced materials.

[0046] As an example, please combine Figure 1 and Figure 4 The first frame strip 10 and the second frame strip 20 can be connected into a right-angle structure by the corner bracket 30. The end face of the first frame strip 10 near the second frame strip 20 is the first inclined surface 11, and the end face of the second frame strip 20 near the first frame strip 10 is the second inclined surface 21. The inclination angles of the first inclined surface 11 and the second inclined surface 21 are complementary.

[0047] For example, the angle between the first inclined plane 11 and the vertical direction is α1, and the angle between the second inclined plane 21 and the vertical direction is α2. The sum of α1 and α2 is 90°. For example, α1 and α2 can both be 45°. Alternatively, α1 can be 30° and α2 can be 60°.

[0048] It is understood that the "complementary" referred to in this application means that it is industrially achievable, such that the first inclined plane 11 and the second inclined plane 21, when joined together, can make the first frame strip 10 and the second frame strip 20 approximately perpendicular. The terms "perpendicular," "complementary," and "90°" used in this application are all industrially achievable and may have certain unavoidable errors compared to absolute mathematical values.

[0049] The corner bracket 30 has a first connector 31 and a second connector 32 connected at a preset angle, and the angle between the first connector 31 and the second connector 32 is adapted to the connection angle requirements of the first frame strip 10 and the second frame strip 20.

[0050] For example, when the first frame strip 10 and the second frame strip 20 need to be connected to form a structure similar to a vertical connection, please refer to [reference needed]. Figure 2 and Figure 3 The included angle between the first connector 31 and the second connector 32 can be 90°.

[0051] For example, when the first frame strip 10 and the second frame strip 20 need to be connected into a bent structure with an included angle of 120°, the included angle between the first connector 31 and the second connector 32 can be 120°.

[0052] For example, when the first frame strip 10 and the second frame strip 20 need to be connected to form a structure similar to a horizontal one, the included angle between the first connector 31 and the second connector 32 can be 180°.

[0053] To facilitate on-site installation by operators, the first connector 31 in the corner bracket 30 provided in this application embodiment includes a first connecting sleeve 311 and a first connecting arm 312. The first connecting sleeve 311 is bonded to the inner wall of the end of the first frame strip 10 through a first fiber resin adhesive layer 33. The second mating part 3121 at the first connecting arm 312 can be engaged with the first mating part 3113 at the first connecting sleeve 311, thereby realizing the connection between the first frame strip 10 and the second frame strip 20.

[0054] This application does not limit how the second mating member 3121 engages with the first mating member 3113. In some embodiments, please refer to [the relevant documentation]. Figure 2 The first mating component 3113 includes a third opening disposed on the side wall of the first connecting sleeve 311, which communicates with the first channel 3111. The second mating component 3121 includes a boss protruding from the end of the first connecting arm 312. When the first connecting arm 312 is connected to the first connecting sleeve 311, the boss retracts, passes through the first opening into the first channel 3111 to the position of the third opening, and then springs back to engage with the third opening. By utilizing the convex-concave engagement of the boss and the third opening, the connection between the first connecting arm 312 and the first connecting sleeve 311 can be achieved.

[0055] This application does not limit the specific location of the third opening. In some embodiments, the first connecting sleeve 311 can be a through-slot structure or a hollow tubular structure, and the first mating member 3113, which is the third opening, can be located at the end of the through-slot structure or the hollow tubular structure away from the first opening 3112. That is, the first opening 3112 and the first mating member 3113, which is the third opening, are located at the two ends of the through-slot structure and the hollow tubular structure, respectively.

[0056] Alternatively, in some embodiments, please continue to refer to Figure 2 The first connecting sleeve 311 can be a through-slot structure or a hollow tubular structure, and the first mating member 3113, which is the third opening, can be located in the middle of the side wall of the through-slot structure or the hollow tubular structure along the axial direction. Furthermore, in some embodiments, a third opening is provided at each of the two opposite side walls of the first connecting sleeve 311, and two opposite bosses can be provided at the first connecting arm 312, and the two bosses of the first connecting arm 312 can be inserted into the two third openings one by one.

[0057] It is understood that the material of the first connecting arm 312 provided in this application embodiment has a certain degree of toughness, enabling it to deform, allowing the boss to contract under external force and rebound after the external force is removed. As an example, the material of the first connecting arm 312 can be a metal or a resin. For example, the material of the first connecting arm 312 can be aluminum or an aluminum alloy. Alternatively, the material of the first connecting arm 312 can be epoxy resin or rubber, or other engineering resins.

[0058] Furthermore, this application does not limit how the boss at the first connecting arm 312 retracts; in some embodiments, please refer to [the documentation / reference needed]. Figure 1 The first connecting arm 312 can be configured as a hollow structure in the middle. When the first connecting arm 312 is connected to the first connecting sleeve 311, the first connecting arm 312 can deform and shrink towards the hollow structure, thereby causing the boss to shrink towards the hollow structure, so that the boss can pass through the first opening 3112 into the first channel 3111 to the position of the third opening, and then the boss springs back and engages with the third opening.

[0059] Furthermore, in order to facilitate the insertion of the boss at the first connecting arm 312 into the first channel 3111 of the first connecting sleeve 311, in some possible embodiments, the end of the first connecting arm 312 away from the second connecting member 32 can be set as a pointed structure, and the connection between the pointed structure and the middle part of the first connecting arm 312 forms a stepped boss.

[0060] It is understood that a sharp-angled structure may include a bevel. Alternatively, please see... Figure 2 The pointed structure can be two connected inclined surfaces. The sidewall of the first connecting arm 312 protrudes outward at the connection with the inclined surface to form a stepped boss.

[0061] Alternatively, in some embodiments, the second mating member 3121 includes two connecting plates located at the end of the first connecting arm 312. The two connecting plates are arranged relatively apart, with a boss on the side of one connecting plate facing away from the other, or both connecting plates have bosses on their outer sides. Due to the gap between the two connecting plates, under the action of external force, the ends of the two connecting plates can be brought closer together, allowing the boss and both connecting plates to pass through the first opening 3112 into the first channel 3111. During the movement of the boss and the two connecting plates within the first channel 3111, they are constantly subjected to pressure from the inner wall of the first connecting sleeve 311 and are in a contracted state. When the boss moves to the position of the first mating member 3113, the first mating member 3113 causes the pressure on the boss to disappear, allowing the two connecting plates to spring back, thereby engaging the boss with the first mating member 3113.

[0062] Alternatively, in other embodiments, the boss can be provided at the end of the first connecting arm 312, and an elastic deformable material can be provided between the boss and the end of the first connecting arm 312.

[0063] This application does not limit the first mating member 3113 to be an open structure or the second mating member 3121 to be a boss structure. In some embodiments, the first mating member 3113 can be a retractable boss, and the second mating member 3121 can be an opening provided on the outer wall of the first connecting arm 312. The retraction of the boss structure of the first mating member 3113 can be achieved by providing an elastic element such as a spring between the boss and the inner wall of the first connecting sleeve 311. To facilitate the movement of the first connecting arm 312 within the first connecting sleeve 311, the boss of the first mating member 3113 can be set as a wedge shape.

[0064] Furthermore, this application does not limit the specific structure of the second connector 32. For some embodiments, please refer to... Figure 3 The second connecting member 32 includes a second connecting sleeve 321 and a second connecting arm 322. The second connecting sleeve 321 is bonded to the inner wall of the end of the second frame strip 20 by a second fiber resin adhesive layer 34. The interior of the second connecting sleeve 321 is provided with a second channel 3211 and a second opening 3212 communicating with the second channel 3211. A third mating member 3213 is provided at the circumferential edge of the second connecting sleeve 321. The second connecting arm 322 is provided with a fourth mating member 3221, which is used to pass through the second opening 3212 into the second channel 3211 and engage with the third mating member 3213.

[0065] This application does not limit the specific mating form of the third mating part 3213 and the fourth mating part 3221. The appropriate choice can be made by referring to the mating method of the first mating part 3113 and the second mating part 3121.

[0066] Alternatively, in some embodiments, please continue to refer to Figure 2 The second connector 32 includes a second connecting arm 322, which is bonded to the inner wall of the end of the second frame strip 20 via a second fiber resin adhesive layer 34. By directly bonding the second connecting arm 322 of the second connector 32 to the inner wall of the second frame strip 20 via the second fiber resin adhesive layer 34, the second connecting sleeve 321 can be omitted, thus saving costs.

[0067] Furthermore, this application does not limit the specific shape of the first connecting sleeve 311, the second connecting sleeve 321 / second connecting arm 322, and relevant personnel can make corresponding adjustments according to the shape of the inner cavity of the frame strip.

[0068] In some embodiments, the internal cavity of the frame strip can be a quadrangular prism structure, and the first connecting sleeve 311, the second connecting sleeve 321 / the second connecting arm 322 can be quadrangular prisms in shape, so as to bond the quadrangular prism structure to the corresponding frame strip using the corresponding fiber resin adhesive layer.

[0069] The first fiber resin adhesive layer 33 and the second fiber resin adhesive layer 34 are used to bond the corresponding frame strips and connectors. The first fiber resin adhesive layer 33 and the second fiber resin adhesive layer 34 refer to existing fiber resin blends, such as existing carbon fiber reinforced thermoplastic resin materials. The resin adhesive in the fiber resin blend is applied to the surface of the corresponding connector / sleeve before curing, and then the connector / sleeve is inserted into the corresponding frame strip, allowing the resin adhesive to cure and bond between the corresponding frame strip and the connector / sleeve.

[0070] It is understandable that, due to the frequent pores between fibers, the resin adhesive has a certain degree of fluidity before curing. Therefore, the cured resin adhesive will adhere to the pores between fibers and the surface of the fibers in the fiber resin adhesive layer. The frame assembly 1 provided in this application embodiment may include multiple sets of first frame strips 10, second frame strips 20, and corner brackets 30. Users can select the number of frame strips as needed to assemble frame structures of different shapes.

[0071] Furthermore, in some embodiments, the frame assembly 1 includes two sets of first frame strips 10 and second frame strips 20 connected by corner brackets 30, a first fiber resin adhesive layer 33, and a second fiber resin adhesive layer 34. (See also...) Figure 4 ( Figure 4 In the middle, corner code 30, first fiber resin adhesive layer 33 and second fiber resin adhesive layer 34 are located inside the frame strip, and the two sets of first frame strips 10 and second frame strips 20 are connected end to end in sequence.

[0072] It is understood that the aforementioned frame assembly 1 includes two first frame strips 10, two second frame strips 20, and four corner brackets 30. A first connecting sleeve 311 is bonded to the inner walls of both ends of each first frame strip 10 via a first fiber resin adhesive layer 33. A second connecting member 32 is bonded to the inner walls of both ends of each second frame strip 20 via a second fiber resin adhesive layer 34. Then, the four frame strips are bonded together end-to-end to form a quadrilateral frame structure.

[0073] The internal cavities of the first frame strip 10 and the second frame strip 20 are both quadrangular prism structures, and the inclination angle of their end faces is 45°. The end of the first connecting arm 312 is provided with a pointed structure, which includes two inclined slopes. The connection between the two slopes and the middle part of the first connecting arm 312 forms a stepped second mating part 3121. The first connecting sleeve 311 is a hollow quadrangular prism structure, and the two side walls in the middle of the quadrangular prism are provided with open first mating parts 3113.

[0074] After attaching the first adhesive piece to the outer wall of both first connecting sleeves 311, before the resin adhesive cures, push the two ends of the first frame strip 10 into the inner wall of the two ends of the first frame strip 10 for interference fit, and then cure.

[0075] The second connector 32 includes a second connecting arm 322. After the second adhesive piece is attached to the outer wall of both second connecting arms 322, before the resin adhesive cures, the two ends of the second frame strip 20 are respectively pushed in to make an interference fit with the inner wall of the two ends of the second frame strip 20, and then cured.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
