[0024] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0025] Related art proposes a mounting structure for attaching photovoltaic modules or other building components to roofs or purlins. The mounting structure includes a base and two screws, each of which is threadedly connected to the base. One screw is connected to the upper side of the base and is threadedly connected to the photovoltaic module or other building component. The other screw is connected to the lower side of the base and extends through the purlin or roof. The screw is fixed to the purlin or roof via threaded fasteners.

[0026] The aforementioned mounting structure requires threaded holes on both the upper and lower ends of the base, and two screws must be connected and secured to the base during installation. This results in complex manufacturing processes and cumbersome on-site installation. Furthermore, to improve the base's structural strength and prevent damage to the threaded holes on the upper and lower ends due to stress concentration, the base's cross-sectional area must be increased, resulting in higher material costs.

[0027] In response to the defects of the installation structure in the above-mentioned related art, the embodiment of the present application provides a fixed support for fixing a second building component on a first building component, aiming to reduce the material cost and processing cost of the fixed support and also to improve the installation convenience.

[0028] Figure 1 A schematic structural diagram of the fixed support 1 provided in an embodiment of the present application is shown. Figure 2 FIG. 1 shows an exploded structural diagram of the fixed support 1 provided in an embodiment of the present application. Figure 1 and Figure 2 As shown, the fixed support 1 provided in the embodiment of the present application includes a column 10 , a cover 20 and a fastener 30 .

[0029] Specifically, the outer wall of the column 10 is provided with a threaded structure for threaded connection with the second building component. The cover 20 includes a body 21 and a backing plate 22. The body 21 is wrapped around the outer side of the backing plate 22. The body 21 and the backing plate 22 together define a through hole 20a for the column 10 to pass through. The outer wall of the column 10 is fixedly connected to the inner wall of the through hole 20a. The body 21 is used to securely connect to the surface of the second building component. A fastener 30 is fixedly disposed within the interior of the first building component. The fastener 30 is sleeved on the column 10 and threadedly connected to the threaded structure of the column 10.

[0030] In the embodiments of the present application, the first building component may include a purlin or a building panel, etc., and the second building component may include a photovoltaic module, electrical equipment, a bracket or a walking support board, etc. In the description of this application, the surface of the first building component may be understood as the upper surface of the first building component.

[0031] For example, the first building component may have a mounting hole extending inward from the surface of the first building component, and the fastener 30 may be fixedly disposed within the mounting hole. The column 10 may be a threaded rod, with the portion of the column 10 located below the cover 20 adapted to penetrate into the mounting hole and form a threaded connection with the fastener 30. The cover 20 is located above the first building component and fixedly connected to the upper surface of the first building component, thereby securing the fixing support 1 to the first building component. The second building component may be threadedly connected to the portion of the column 10 located above the cover 20, thereby securing the second building component to the fixing support 1. Thus, the second building component is securely mounted on the first building component.

[0032] It is understandable that the cover 20 covers the surface of the first building component and is used to cover the gap between the inner peripheral wall of the installation hole on the first building component and the outer peripheral wall of the column 10, thereby playing a sealing role and achieving the purpose of waterproofing.

[0033] For example, the main body 21 can be made of a flexible material to cover the surface of the first building component and to block the gap between the outer peripheral wall of the column 10 and the inner peripheral wall of the mounting hole of the first building component. The backing plate 22 can be made of a rigid material to provide rigid support for the cover 20, thereby improving the structural strength of the cover 20 and thus enhancing the stability of the fixed connection between the cover 20 and the column 10. The backing plate 22 can be disposed inside the main body 21. In other words, the main body 21 is covered by the outside of the backing plate 22 so that the backing plate 22 is not exposed to the outside world. In this way, the cover 20 can be ensured to have a certain degree of waterproof performance and good structural strength.

[0034] According to the fixed support 1 of the embodiment of the present application, by providing an integrally formed column 10, and by providing a cover 20 and a fastener 30, the fastener 30 can be disposed inside the first building component, and the cover 20 can be fixedly connected to the surface of the first building component. This arrangement achieves the fixed connection of the fixed support 1 to the first building component, and the threaded connection between the column 10 and the second building component, thereby achieving the fixed installation of the second building component on the first building component. Because the fixed support 1 of the embodiment of the present application can only use a single screw as the column 10 and does not require a base, compared to the installation structure in the related art, the amount of manufacturing material of the fixed support 1 is reduced, thereby reducing the material cost of the fixed support 1. Moreover, the simple structure does not require a complex preparation process, which helps to reduce the manufacturing cost of the fixed support 1. Secondly, during installation of the fixed support 1, it is only necessary to thread the uprights 10 into the fasteners 30 fixedly disposed within the first building component and to securely connect the cover 20 to the surface of the first building component. This reduces the difficulty of assembling the fixed support 1 onto the first building component and significantly improves the ease of assembling the second building component onto the first building component. Furthermore, by positioning the backing plate 22 within the body 21, for example, by allowing the body 21 to be positioned outside the backing plate 22 through an injection molding process, the manufacturing process of the cover 20 is simplified, thereby reducing the manufacturing cost of the cover 20 and further reducing the manufacturing cost of the fixed support 1.

[0035] In one embodiment, the body 21 is formed on the outer side of the backing plate 22 by an injection molding process.

[0036] For example, the body 21 can be disposed on the outer side of the backing plate 22 by a metal insert injection molding process. The metal insert injection molding process is a type of insert model in which a metal insert is pre-fixed in an appropriate position in a mold, and then plastic is injected to form the mold. After the mold is opened, the insert is tightly embedded in the product by the cooled and solidified plastic.

[0037] By utilizing the metal insert injection molding process, the body 21 can be directly injection-molded on the outer side of the backing plate 22 , thereby eliminating the need for assembly between the backing plate 22 and the body 21 , thereby saving the manufacturing cost of the cover 20 .

[0038] Optionally, the backing plate 22 is made of metal, and the body 21 is made of thermoplastic polyolefin or polyvinyl chloride.

[0039] In other examples of the present application, the material of the main body 21 can also be other types of polymer materials, such as polyethylene, polypropylene, polystyrene, polycarbonate, etc. The specific material can be flexibly selected according to actual conditions, and the embodiments of the present application are not specifically limited here.

[0040] Preferably, the backing plate 22 can be made of stainless steel. The body 21 can be made of thermoplastic polyolefin. It is understood that thermoplastic polyolefin is made by mixing polyolefin plastics such as polypropylene (PP) or polyethylene (PE) with rubber or other elastomers. It combines the advantages of plastic and rubber, and has excellent heat resistance, weather resistance, chemical resistance, and tear resistance. This improves the corrosion resistance and durability of the body 21, and provides better sealing performance, enabling the cover 20 to have better waterproof performance.

[0041] In one embodiment, the cross-sectional shapes of the pad 22 and the body 21 are both circular, and the ratio of the radius of the pad 22 to the radius of the body 21 is greater than or equal to 1 / 4 and less than or equal to 1 / 2.

[0042] Preferably, the ratio of the radius of the backing plate 22 to the radius of the body 21 can be 1 / 3. For example, the radius of the backing plate 22 can be 25 mm, and the radius of the body 21 can be 75 mm. The center of the backing plate 22 is arranged to coincide with the center of the body 21, thereby ensuring that the projection of the backing plate 22 on the first building component is within the range of the projection of the body 21 on the first building component.

[0043] Furthermore, the portion of the body 21 corresponding to the backing plate 22 protrudes outward and defines a cavity therein for accommodating the backing plate 22. The surface of the body 21 adjacent to the first building component is flat, allowing the surface of the body 21 adjacent to the first building component to conform to the surface of the first building component, thereby increasing the contact area between the cover 20 and the first building component and improving the sealing performance of the cover 20.

[0044] Optionally, the first building component includes a coiled material layer, and a surface of the coiled material layer forms the surface of the first building component; wherein the body 21 is connected to the surface of the coiled material layer by welding.

[0045] For example, the coiled material layer can be made of the same material as the body 21 of the cover 20, such as thermoplastic polyolefin or polyvinyl chloride. The surface of the coiled material layer can be fixedly connected to the surface of the body 21 by a hot air welding process.

[0046] In one embodiment, the column 10 includes a first section 11, a second section 12, and a third section 13 connected in sequence in the axial direction. The first section 11 and the third section 13 are respectively provided with a threaded structure, and the threaded structure on the first section 11 is used for threaded connection with the second building component, and the threaded structure on the third section 13 is used for threaded connection with the fastener 30. The outer peripheral wall of the second section 12 is fixedly connected to the inner peripheral wall of the through hole 20a.

[0047] It is understandable that the length of the second section 12 may be greater than or equal to the height of the through hole 20 a of the cover 20 to ensure that the outer peripheral wall of the second section 12 can be fixedly connected to the inner peripheral wall of the through hole 20 a .

[0048] For example, the ratio of the length of the third segment 13 to the length of the first segment 11 may be 0.4 to 0.8. Preferably, the ratio of the length of the third segment 13 to the length of the first segment 11 may be 0.6. In a specific example, the length of the first segment 11 may be 100 mm, the length of the third segment 13 may be 60 mm, and the length of the second segment 12 may be 8 mm.

[0049] Optionally, the outer peripheral wall of the second section 12 is threadedly connected or welded to the inner peripheral wall of the through hole 20a.

[0050] In some examples, the outer peripheral wall of the second section 12 may be provided with a threaded structure, and accordingly, the inner peripheral wall of the through hole 20a may also be provided with a matching threaded structure at least on the corresponding portion of the gasket, thereby enabling a threaded connection between the second section 12 and the through hole 20a.

[0051] In other examples, the outer wall of the second section 12 is formed with a welding surface for welding to the inner wall of the through hole 20a. More specifically, the outer wall of the second section 12 and the inner wall of the through hole 20a can be fixedly connected by laser welding.

[0052] In the embodiment of the present application, the fastener 30 may be a nut, and the column 10 is fixedly mounted on the first building component through a threaded connection between the nut and the column 10 .

[0053] In one embodiment, the fastener 30 includes a rivet nut having a screw hole 30a extending therethrough in its height direction. The screw hole 30a is sleeved on the periphery of the column 10 and is threadedly connected to the threaded structure. The outer peripheral wall of the rivet nut deforms under axial stress to form a stop structure, which is used to clamp and fix the rivet nut to the interior of the first building component.

[0054] In the embodiments of the present application, the rivet nut can specifically be a pull rivet nut or a flip rivet nut, which is not specifically limited in the embodiments of the present application. Preferably, the rivet nut can be a pull rivet nut. It is understood that the rivet nut, also known as a nail nut, blind nut or pull cap, is a tool used to install a threaded fastener on the surface of a material, and is particularly suitable for thin plates or occasions where it is difficult to operate from the back. The rivet nut is installed using a special installation tool (such as a pull rivet gun) and can be operated on one side on the second surface of the first building component, thereby providing a reliable threaded anchor point for the column 10.

[0055] In some specific examples, the rivet nut can be placed in the mounting hole of the first building component first, and then the pull rod of the rivet gun is inserted into the screw hole 30a of the rivet nut. Then, the rivet gun is started. The rivet nut is deformed under the action of axial stress, causing the tail to expand to form a stop structure, so that the rivet nut is tightly clamped and fixed to the inside of the first building component through the stop structure.

[0056] Through the above embodiment, the stability of the fastener 30 in the first building component can be improved, and the arrangement of the fastener 30 in the first building component is relatively simple, which is conducive to further improving the installation convenience of the fixing support 1.

[0057] As another aspect of the embodiments of the present application, the embodiments of the present application further provide a building assembly. The building assembly of the embodiments of the present application includes a first building component, a second building component, and at least one fixing support 1 of the above embodiments of the present application, wherein the fixing support 1 is used to fix the second building component on the first building component.

[0059] According to the building assembly provided in the present application, by utilizing the fixing support 1 of the above embodiment of the present application, the installation cost of the second building component on the first building component can be effectively reduced, and the assembly difficulty can be significantly reduced, thereby improving the installation convenience.
