[0002] At present, the materials used in the photovoltaic bracket design atlas are basically the same cross-sectional style, such as C-shaped steel or U-shaped steel. However, with the continuous updating of the scheme and the switching between C-shaped steel and U-shaped steel bracket schemes, the existing technology does not have a mixed bracket scheme of C-steel and U-steel, which leads to a large amount of raw materials piled up in the warehouse that cannot be consumed, resulting in a waste of bracket materials. [Contents of the utility model]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a connection structure between U-shaped steel and C-shaped steel in the outward direction of the photovoltaic bracket, so as to solve the problem that C-steel and U-steel cannot be mixed in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a connection structure of U-shaped steel and C-shaped steel on the outward direction of the photovoltaic bracket, including U-shaped steel and C-shaped steel, the U-shaped steel opening is facing upward, the C-shaped steel opening is facing sideways, and a special-shaped component connector is provided between the U-shaped steel and the C-shaped steel, the special-shaped component connector includes a first connecting edge and a second connecting edge which are perpendicular to each other, the first connecting edge is connected to the bottom surface of the U-shaped steel by a first bolt, and the second connecting edge is connected to the bottom surface of the C-shaped steel by a second bolt.

[0005] Preferably, a reinforcing rib is provided between the first connecting edge and the second connecting edge.

[0006] Preferably, the first connecting edge and the second connecting edge are two side edges of an angle steel, the reinforcing rib is a steel plate with a right-angled triangle or right-angled trapezoidal structure, and the reinforcing rib is welded to the first connecting plate and the second connecting plate.

[0007] Preferably, two reinforcing ribs are provided, and the first connecting edge and the second connecting edge are separated into three connecting areas.

[0008] Preferably, three first fixing holes are provided on the first connecting edge corresponding to three connecting areas, and the first fixing holes are connected with first bolts.

[0009] Preferably, the first fixing hole is a waist-shaped hole.

[0010] Preferably, a second fixing hole is provided in a middle connecting area corresponding to the second connecting edge, and the second fixing hole is connected with a second bolt.

[0011] Preferably, the second fixing hole is a waist-shaped hole.

[0012] Preferably, the bottom surface of the U-shaped steel and / or C-shaped steel is evenly distributed with connection holes along the length direction.

[0013] Preferably, a crossbeam perpendicularly intersecting the U-shaped steel is fixed on the U-shaped steel, and the photovoltaic module is installed on the crossbeam; and / or the U-shaped steel and the C-shaped steel intersect obliquely or perpendicularly.

[0014] The utility model adopts the above technical solution and has the following beneficial effects:

[0015] 1. A special-shaped component connector is provided between the U-shaped steel and the C-shaped steel, wherein the special-shaped component connector includes a first connecting edge and a second connecting edge which are perpendicular to each other, the first connecting edge is connected to the bottom surface of the U-shaped steel by a first bolt, and the second connecting edge is connected to the bottom surface of the C-shaped steel by a second bolt. Therefore, the problem of mutual connection between the C-shaped steel and the U-shaped steel bracket is solved, the material consumption speed is increased, and the problem of material waste caused by the inability to consume materials when switching between the C-shaped steel and the U-shaped steel bracket schemes is solved.

[0016] 2. A reinforcing rib is provided between the first connecting edge and the second connecting edge, thereby enhancing the overall structural strength of the special-shaped component connector.

[0017] 3. The first connecting edge and the second connecting edge are angle steels, and the reinforcing ribs are steel plates with a right-angled triangle or right-angled trapezoidal structure. The reinforcing ribs are welded to the first connecting plate and the second connecting plate, and scraps can be used to make special-shaped component connectors, thereby saving materials and reducing costs.

[0018] 4. Two reinforcing ribs are provided, which not only enhance the overall structural strength of the special-shaped component connector, but also separate the first connecting edge and the second connecting edge into three connecting areas. Correspondingly, three first fixing holes are provided in the three connecting areas corresponding to the first connecting edge, and a second fixing hole is provided in the middle connecting area corresponding to the second connecting edge.

[0019] 5. The three first fixing holes are connected to the three first bolts correspondingly, thereby ensuring that the first connecting edge is reliably connected to the bottom surface of the U-shaped steel to stably support the bottom surface of the U-shaped steel.

[0020] 6. The reason why the second connecting edge is only provided with a second fixing hole connected with the second bolt in the middle connecting area is that in this way, when the second bolt is not tightened, the C-shaped steel can be rotated to adjust the angle between the C-shaped steel and the U-shaped steel. After the position is adjusted, the second bolt can be fully tightened.

[0021] 7. The first fixing hole and the second fixing hole can be designed as waist-shaped holes to facilitate connection with bolts and connecting holes.

[0022] 8. The bottom surfaces of the U-shaped steel and the C-shaped steel are evenly distributed with connection holes along the length direction to facilitate the adjustment of the connection position between the U-shaped steel and the C-shaped steel.

[0023] 9. U-shaped steel is used as the diagonal beam of the photovoltaic bracket, on which the cross beam is installed, and the photovoltaic modules are installed on the cross beam. At the same time, the U-shaped steel and the C-shaped steel are obliquely intersected or vertically intersected, that is, the C-shaped steel is used as a column or diagonal brace. This is a common photovoltaic bracket structure, which can be widely used on photovoltaic brackets, solving the problem of material accumulation caused by the inability to mix C steel and U steel in the prior art.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0030] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0031] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0032] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "horizontal", "vertical", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0035] Reference Figures 1 to 3 As shown, a connection structure of U-shaped steel and C-shaped steel in the outward direction of the photovoltaic support includes U-shaped steel 1 and C-shaped steel 2. The opening direction of the U-shaped steel 1 is perpendicular to the opening direction of the C-shaped steel 2. For example, the opening of the U-shaped steel faces upward, and the opening of the C-shaped steel faces sideways. A special-shaped component connector 3 is provided between the U-shaped steel 1 and the C-shaped steel 2. The special-shaped component connector 3 includes a first connecting edge 31 and a second connecting edge 32 that are perpendicular to each other. The first connecting edge 31 is connected to the bottom surface of the U-shaped steel by a first bolt, and the second connecting edge 32 is connected to the bottom surface of the C-shaped steel by a second bolt.

[0036] The above technical solution solves the problem of connecting the C-shaped steel and U-shaped steel brackets to each other by providing a special-shaped component connector between the U-shaped steel and the C-shaped steel, increases the material consumption rate, and solves the problem of material waste caused by the inability to consume materials when switching between the C-shaped steel and U-shaped steel bracket solutions.

[0037] In order to enhance the overall structural strength of the special-shaped component connector, a reinforcing rib 33 is provided between the first connecting edge 31 and the second connecting edge 32 .

[0038] Specifically, the first connecting edge 31 and the second connecting edge 32 are two side edges of the angle steel, the reinforcing rib plate 33 is a steel plate of a right-angled triangle or a right-angled trapezoidal structure, and the reinforcing rib plate is welded to the first connecting plate and the second connecting plate. Whether it is an angle steel or a steel plate of a right-angled triangle or a right-angled trapezoidal structure, leftover materials can be used, thereby effectively utilizing leftover materials to reduce costs.

[0039] Furthermore, the reinforcing ribs 33 are provided with two pieces, and the first connecting edge and the second connecting edge are separated into three connecting areas. The first connecting edge 31 is provided with three first fixing holes 311 corresponding to the three connecting areas, and the first fixing holes 311 are connected to the first bolts. The three first fixing holes are connected to the three first bolts corresponding to the three first fixing holes, so as to ensure that the first connecting edge is reliably connected to the bottom surface of the U-shaped steel to stably support the bottom surface of the U-shaped steel. The second connecting edge 32 is provided with a second fixing hole 321 corresponding to a middle connecting area, and the second fixing hole 321 is connected to the second bolt. The reason why the second connecting edge is only provided with a second fixing hole 321 in a middle connecting area to connect with the second bolt is that in this way, when the second bolt is not tightened, the C-shaped steel can be rotated to adjust the angle between the C-shaped steel and the U-shaped steel, and the second bolt can be fully tightened after the position is adjusted.

[0040] Preferably, the first fixing hole and the second fixing hole can be designed as waist-shaped holes to facilitate connection with the bolts and the connecting holes.

[0041] In order to facilitate the connection with the special-shaped component connector, the bottom surfaces of the U-shaped steel 1 and the C-shaped steel 2 are evenly distributed with connection holes along the length direction, so as to facilitate the adjustment of the connection position between the U-shaped steel and the C-shaped steel and connect them through the special-shaped component connector.

[0042] In this embodiment, a crossbeam perpendicular to the U-shaped steel is fixed on the U-shaped steel, and the photovoltaic module is installed on the crossbeam. The U-shaped steel and the C-shaped steel intersect obliquely or perpendicularly. That is, the C-shaped steel is used as a column or a diagonal brace. This is a common photovoltaic support structure, which can be widely used on photovoltaic supports, solving the problem of material accumulation caused by the inability to mix C-steel and U-steel in the prior art.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
