[0025] In the following, only some exemplary embodiments are simply described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are to be regarded as illustrative in nature and not restrictive.

[0026] In the related art, an installation structure for installing other building components such as photovoltaic modules on a roof or purlin is proposed. The installation structure includes a seat body and two lead screws, and the two lead screws are respectively threadedly connected to the seat body. One of the lead screws is connected to the upper side of the seat body and is used for threadedly connecting with other building components such as photovoltaic modules; the other lead screw is connected to the lower side of the seat body and penetrates through the purlin or the roof, and the lead screw forms a fixation with the purlin or the roof through a threadedly connected fastener.

[0027] In the above installation structure, since threaded holes need to be machined at the upper and lower ends of the seat body respectively, and two lead screws need to be connected and fixed to the seat body during the installation process, there are defects such as complex processing technology and cumbersome on-site installation process. Moreover, in order to improve the structural strength of the seat body and avoid damage to the threaded holes at the upper and lower ends under stress concentration, it is necessary to correspondingly increase the cross-sectional area of the seat body, resulting in a relatively high material cost of the seat body.

[0028] In view of the defects existing in the installation structure in the above related technologies, the embodiment of the present application provides a fixed support for fixedly installing a second building component on a first building component, aiming to reduce the material cost and processing cost of the fixed support, and also being beneficial to improving the installation convenience.

[0029] Figure 1 FIG. shows a schematic structural diagram of the fixed support 1 provided by the embodiment of the present application. Figure 2 FIG. shows an exploded structural diagram of the fixed support 1 provided by the embodiment of the present application. As Figure 1 and Figure 2 shown, the fixed support 1 provided by the embodiment of the present application includes a column 10, a cover 20, and a fastener 30.

[0030] Specifically, a threaded structure is provided on the outer peripheral wall of the column 10, and the threaded structure is used for threaded connection with the second building component. The cover 20 is provided with a through hole 20a for the column 10 to pass through, and the outer peripheral wall of the column 10 is fixedly connected to the inner peripheral wall of the through hole 20a. The cover 20 is used for fixedly connecting with the surface of the first building component. The fastener 30 is fixedly arranged inside the first building component, and the fastener 30 is sleeved on the column 10 and is in threaded connection with the threaded structure of the column 10.

[0031] In the embodiment of the present application, the first building component may include purlins or building panels, etc., and the second building component may include photovoltaic modules, electrical equipment, brackets, or walking support plates, etc. In the description of the specification of the present application, the surface of the first building component can be understood as the upper surface of the first building component.

[0032] Exemplarily, the first building component may be provided with an installation hole, and the installation hole extends from the surface of the first building component towards the inside. The fastener 30 can be fixedly arranged inside the installation hole. The column 10 can be a lead screw, and the part of the column 10 located below the cover 20 is adapted to penetrate into the inside of the installation hole and form a threaded connection with the fastener 30. The cover 20 is located on the upper side of the first building component and is fixedly connected to the upper surface of the first building component, thereby realizing the connection and fixation of the fixed support 1 on the first building component. The second building component can be in threaded connection with the part of the column 10 located above the cover 20 to realize the fixed connection between the second building component and the fixed support 1. Thus, the fixed installation of the second building component on the first building component is realized.

[0033] It can be understood 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 mounting 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.

[0034] According to the fixed support 1 of the embodiment of the present application, by providing the integrally formed column 10, and by providing the cover 20 and the fastener 30, the fastener 30 can be arranged inside the first building component, and the cover 20 can be fixedly connected to the surface of the first building component. With such an arrangement, the fixed connection of the fixed support 1 to the first building component is realized, and the second building component is fixedly installed on the first building component through the threaded connection between the column 10 and the second building component. Since the fixed support 1 of the embodiment of the present application can use only one screw rod as the column 10 and does not require a seat body, thus, compared with the installation structure in the related art, the amount of manufacturing materials for the fixed support 1 is saved, thereby saving the material cost of the fixed support 1, and the structure is simple and does not require complex preparation processes, which is beneficial to reducing the manufacturing cost of the fixed support 1. In addition, during the installation process of the fixed support 1, it is only necessary to thread-connect the column 10 with the fastener 30 fixedly arranged inside the first building component and fixedly connect the cover 20 to the surface of the first building component. Therefore, the assembly difficulty of the fixed support 1 on the first building component is reduced, and the assembly convenience of the second building component on the first building component is significantly improved.

[0035] In one embodiment, the cover 20 includes a stacked body 21 and at least one backing plate 22. The body 21 and the at least one backing plate 22 jointly define a through hole 20a. At least a part of the body 21 covers the surface of the first building component, and the backing plate 22 is fixedly connected to the body 21.

[0036] Exemplarily, the body 21 can be made of a flexible material, which is used to cover the surface of the first building component and can 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, which is used to provide rigid support for the cover 20 to enhance the structural strength of the cover 20.

[0037] Through the above embodiment, it can not only ensure that the cover 20 has a certain waterproof performance but also ensure that the cover 20 has good structural strength.

[0038] Optionally, the material of the backing plate 22 is metal, and the material of the body 21 includes thermoplastic olefin 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 material of the backing plate 22 may be stainless steel. The material of the body 21 may be 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 plastics and rubber and has good heat resistance, weather resistance, chemical resistance and tear resistance. As a result, the corrosion resistance and durability of the body 21 can be improved, and it has good sealing performance, which can make the cover 20 have good waterproof performance.

[0041] In some examples, the number of the backing plate 22 may be one, and the backing plate 22 is disposed on a side of the backing plate 22 that is adjacent to or away from the first building component.

[0042] Optionally, there are two backing plates 22 and they are respectively arranged on two opposite sides of the main body 21 , and the projection of the backing plate 22 on the first building component is within the range of the projection of the main body 21 on the first building component.

[0043] Exemplarily, the cross-sectional shapes of the pad 22 and the body 21 may be circular, and the center of the pad 22 is arranged to coincide with the center of the body 21, and the radius of the pad 22 is smaller than the radius of the body 21, so that the projection of the pad 22 on the first building component is located within the range of the projection of the body 21 on the first building component. The ratio of the radius of the pad 22 to the radius of the body 21 may be between 1 / 4 and 1 / 2. The two pads 22 are respectively the first pad 22 and the second pad 22, the first pad 22 is located on the side of the body 21 away from the first building component, and the second pad 22 is located on the side of the body 21 adjacent to the first building component. It can be understood that the portion of the body 21 not blocked by the second pad 22 is arranged to fit the surface of the first building component.

[0044] Optionally, the body 21 is bonded to the backing plate 22. For example, the body 21 and the backing plate 22 may be bonded to each other by structural adhesive, and the structural adhesive may be epoxy resin adhesive, polyurethane adhesive or acrylic adhesive.

[0045] Optionally, the first building component comprises a coiled material layer, and a surface of the coiled material layer forms a surface of the first building component; wherein the body 21 is connected to the surface of the coiled material layer by welding.

[0046] Exemplarily, the coil 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 coil layer and the surface of the body 21 can be fixedly connected by a hot air welding process.

[0047] In one embodiment, the column 10 includes a first section 11, a second section 12, and a third section 13 that are sequentially connected in the axial direction. The first section 11 and the third section 13 are respectively provided with thread structures. The thread structure on the first section 11 is used for threaded connection with the second building component, and the thread structure on the third section 13 is used for threaded connection with the fastener 30. Among them, the outer peripheral wall of the second section 12 is fixedly connected to the inner peripheral wall of the through hole 20a.

[0048] Exemplarily, the ratio of the length dimension of the third section 13 to the length dimension of the first section 11 can be 0.4 to 0.8. Preferably, the ratio of the length dimension of the third section 13 to the length dimension of the first section 11 can be 0.6. In a specific example, the length dimension of the first section 11 can be 100 mm, the length dimension of the third section 13 can be 60 mm, and the length dimension of the second section 12 can 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 can be provided with a thread structure. Correspondingly, at least the corresponding part of the inner peripheral wall of the through hole 20a on the gasket is also provided with a matching thread structure, so that the second section 12 and the through hole 20a can be threadedly connected.

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

[0052] In the embodiment of the present application, the fastener 30 can be a nut. Through the threaded connection between the nut and the column 10, the fixed installation of the column 10 on the first building component is realized.

[0053] In one embodiment, the fastener 30 includes a riveted nut. The riveted nut has a threaded hole 30a penetrating through in its height direction. The threaded hole 30a is sleeved around the column 10 and is threadedly connected to the thread structure. The outer peripheral wall of the riveted nut deforms under the action of axial stress to form a stop structure, and the stop structure is used to make the riveted nut be snap-fitted and fixed inside the first building component.

[0054] In the embodiments of the present application, the rivet nut may specifically be a blind rivet nut or a reverse rivet nut, and the embodiments of the present application do not make specific limitations thereto. Preferably, the rivet nut may be a blind rivet nut. It can be understood that the rivet nut, also known as a stud nut, blind nut or rivet cap, is a tool for installing threaded fasteners on the surface of materials, and is particularly suitable for thin plates or occasions where it is difficult to operate from the back. The rivet nut is installed through a special installation tool (such as a blind rivet gun), and can perform single-sided operation on the second surface of the first building component, thereby providing a reliable threaded anchoring point for the column 10.

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

[0056] Through the above implementation manner, the stability of the fastener 30 in the first building component can be improved, and the setting manner of the fastener 30 in the first building component is relatively simple, which is beneficial to further improving the installation convenience of the fixed support 1.

[0058] In the embodiments of the present application, the building assembly may be a metal building installed with a photovoltaic system. In some examples, the first building component may include a building panel or a purlin, etc., and the second building component may include a photovoltaic module, electrical equipment, a walking support plate, a bridge, and a guardrail, etc. Any of the above second building components can be fixedly installed on the building panel or purlin through the fixed support 1 of the above embodiments of the present application.

[0059] In one implementation manner, the first building component includes a purlin or a building panel; the second building component includes at least one of a photovoltaic module, electrical equipment, a walkway plate, a lightning protection bracket, and a guardrail; wherein, the first building component is provided with an installation hole, the fastener 30 is fixedly arranged in the installation hole, a part of the column 10 passes through the installation hole and is threadedly connected with the fastener 30, and the second building component is threadedly connected with the part of the column 10 located outside the installation hole.
