DETAILED DESCRIPTION

[0026] The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The expression "comprising" in this document is an "open" expression that merely means that the corresponding part or step is present, but it should not be interpreted as excluding additional parts or steps.

[0029] The rail for the slope roof photovoltaic support comprises a profile body and a rail connecting piece, the profile body has a connecting structure of mutual sliding nesting, two profile bodies are combined through the connecting structure, and are fixedly connected through the rail connecting piece.

[0030] The two profile bodies are combined through the connecting structure, the length of the rail can be adjusted in a certain range, thus the demand of installing photovoltaic components on various special-shaped slope roofs can be met, and the increase of workload and the reduction of efficiency caused by the accurate measurement of size data and the precise cutting of the rail are overcome.

[0031] As shown in Figure 1 and Figure 2 In order to achieve the purpose of the application, a rail for the slope roof photovoltaic support 2 comprises an inner rail 22, an outer rail 21 and an inner-outer rail connecting piece, the inner rail 22 is slidably inserted into the cavity of the outer rail 21, the inner rail 22 and the outer rail 21 are both provided with rail grooves 221 and 211 at corresponding positions, the inner-outer rail connecting piece comprises a connecting plate 12 and connecting bolts 11 respectively arranged in the rail grooves 221 and 211 of the inner rail 22 and the outer rail 21, the inner rail 22 and the outer rail 21 are fixedly connected through the connecting plate 12 and the connecting bolts 11, the rail grooves 221 / 211 are C-shaped or T-shaped, and the T-shaped rail groove is taken as an example, the rail groove 211 of the outer rail is slidably sleeved in the rail groove 221 of the inner rail.

[0032] The inner rail 22 and the outer rail 21 and the inner-outer rail connector can realize the length adjustment of the rail within a certain range, thereby meeting the needs of installing photovoltaic components on various special-shaped slope roofs, overcoming the increase of workload and reduction of efficiency caused by the need for accurate measurement of size data and precise cutting of the existing technology. The inner rail 22 and the outer rail 21 are alternately sleeved, and the length of the rail can be infinitely extended, which brings great convenience to the construction, and the traditional extension of the rail needs to be cut on site, which is time-consuming and laborious. The rail grooves 221 and 211 of the inner rail 22 and the outer rail 21 are arranged on an axis, can be conveniently connected through the connecting plate 12 and the connecting bolts (generally T-shaped bolt assemblies) arranged in the rail grooves 221 / 211 respectively, and can realize the extension of the inner rail outward or the retraction of the outer rail inward within a certain range, thereby conveniently adjusting the length of the entire rail. The appropriate outer rail (for example, slightly shorter than the required size) can be selected on site, and the inner rail of an appropriate size can be selected to assemble the rail of the required accurate size. When the rails of different positions are prefabricated in the factory according to the measured size, the length of the rail can be adjusted, and therefore the accuracy requirement of the cutting size is greatly reduced.

[0033] In Figure 1 In the embodiment example, the rail grooves are arranged on the opposite two sides of the inner rail 22 and the outer rail 21, and the inner rail 22 and the outer rail 21 have H-shaped cavities that are nested with each other. Figure 1 In the example, the H-shaped cavity of the inner rail 22 is 224. The rail profile is provided with rail grooves on both sides, which facilitates the installation and laying of the component.

[0034] In order to improve the strength of the rail, the inner wall between the two rail grooves in the cavity 224 of the inner rail 22 is provided with a reinforcing rib 223.

[0035] In some embodiments, a plurality of convex strips 222 and 212 for forming point contact sliding between the inner rail 22 and the outer rail 21 are respectively arranged on the outer wall of the inner rail 22 and / or the inner wall of the outer rail 21 along the length direction.

[0036] The inner and outer rails are coaxially and slidably nested, the height difference between the inner and outer rails is very small, which is the thickness of the pipe wall of the outer rail, and the whole is more beautiful. The technical scheme of the present application is different from the existing technology which completely depends on the connector to connect different rails. The present application mainly forms a structure that can adjust the overall length of the rail through the structure of mutual sliding and nesting, and the nested structure forms a stable connection between the two rails connected with each other. The connector only plays a locking role. The existing technology can only rely on the connector for connection, and the requirement for the connector is higher, and the length cannot be adjusted. If adjustment is needed, the rail of the new length needs to be cut or replaced, which is time-consuming and laborious.

[0037] This invention also discloses a photovoltaic support system for pitched roofs, using... Figure 4-1 , Figure 4-2 As shown, it is used to install photovoltaic modules. Figure 4-1 and Figure 4-2 This includes a photovoltaic module 1 mounted above the tile 13. The support structure includes any of the aforementioned guide rails 2, and also includes connectors 3, such as... Figure 3 As shown, the connector 3 includes a support plate 7 for connecting to the guide rail 2, a base plate 10 for fixed connection to an external support (e.g., a wooden frame, steel frame, or concrete slab for a pitched roof), and an extension plate 9 connecting the support plate 7 and the base plate 10. The connector 3 is connected to the concrete pitched roof using expansion bolts 4. When the roof is a steel structure roof, self-drilling hexagonal bolts 5 are used for connection; when the roof is a wooden structure roof, self-tapping screws 6 are used for connection. Figure 6 As shown.

[0038] exist Figure 3 and Figure 5 In the example, the extension plate 9 has a horizontal extension plate with bent portions 91 and 92 at both ends. Each of the bent portions 91 and 92 has a connecting hole. The edges of the base plate 10 and the support plate 7 each have connecting portions 101 and 71 that are adapted to the bent portions 91 and 92, respectively. The connecting portions 101 and 71 have mounting holes 102 and 72, respectively. The base plate 10 and the support plate 7 are bolted to both ends of the extension plate 9 through the mounting holes and connecting holes. Both the support plate 7 and the base plate 10 are connected to the extension plate 9 using round-head square-neck bolts 8.

[0039] To facilitate fine-tuning, the connection holes and / or mounting holes are oblong. This allows for adaptation to different tile-shaped component structures and also helps adjust for errors during construction.

[0040] This invention has the following advantages: 1. When adapting to pitched roofs of different sizes, the guide rails use point contact sliding through the cooperation of inner and outer guide rail structures to reduce friction and make the sliding smoother; when the guide rail length is insufficient, the number of inner and outer guide rails can be increased and fixed with connecting plates to extend the guide rails; when the guide rails are extended too long, simply slide the guide rails to the required length and then fix them to reduce the length of the extended guide rails, thus realizing the function of extending and shortening the guide rails without cutting the guide rails, reducing the tools required for on-site operations, reducing the workload of workers, and at the same time making the photovoltaic brackets on the pitched roofs neat and beautiful, maximizing the power generation utilization rate.

[0041] 2, the connecting piece can adapt to different structural forms of roof, only need to change the used parts of the connection, the structure is simple and reliable; when the roof is concrete roof, the connecting piece is connected with the concrete slope roof through expansion bolt, when the roof is steel structure roof, the hexagonal drill tail bolt is used for connection, when the roof is wood structure roof, the self-tapping screw is used for connection.

[0042] 3, multiple waist type holes are installed on the connecting piece, which can adapt to different tile structures on one hand and adjust the error during construction on the other hand. During actual installation, the tiles of the roof may be high height glazed tiles, or low height stone tile or asphalt tile, at this time, the height is adjusted by using the waist type hole on the connecting piece, so that the installation of different tile structures can be realized, and the waist type hole can also adjust the error of on-site construction, thereby reducing the construction period.

[0043] The above shows and describes the basic principles and main features of the present application and the advantages of the present application, and those skilled in the art should understand that the present application is not limited to the above embodiments, the above embodiments and the description in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application, the scope of protection of the present application is defined by the appended claims and their equivalents.
