Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a roof support structure for a photovoltaic support. Background Technology

[0002] Traditional photovoltaic roof support structures, such as Figure 1 As shown, it mainly consists of columns 1', diagonal beams 2', and crossbeams 3', all of which are typically constructed using square tubing. The surfaces of these square tubing structures lack points for installing and connecting fittings, necessitating additional measures during assembly.

[0003] In traditional assembly methods, a slot needs to be cut at the top of the column for the inclined beam to be embedded, and the crossbeam is mounted on top of the inclined beam. To ensure structural stability, the inclined beam and crossbeam need to be connected by a ring-shaped connector and fasteners. This connection method requires self-locking for fixation. However, this method not only requires a large number of connectors, increasing material costs, but also complicates the construction process. In addition, this structure has relatively poor stability, making it difficult to meet the high stability and safety requirements of photovoltaic support systems. Utility Model Content

[0004] The purpose of this invention is to provide a roof support structure for photovoltaic brackets to solve the problems existing in traditional structures, improve the stability and construction efficiency of the structure, and reduce material costs.

[0005] To achieve the above objectives, the solution of this utility model is: a roof support structure for a photovoltaic bracket, comprising columns, inclined beams and crossbeams;

[0006] The columns are supported between the ground and the roof, the inclined beams are erected on top of the columns, and the crossbeams are erected above the inclined beams.

[0007] The column and the inclined beam are connected by a first connector, and the inclined beam and the crossbeam are connected by a second connector.

[0008] Profiles used as columns, diagonal beams and crossbeams have mounting grooves on their main surface;

[0009] The connector and the profile are fixedly connected by a fastening assembly, which includes a bolt and a nut. The head of the bolt is limited in the mounting groove of the profile, and the shank of the bolt passes through the connector and is fastened by the nut.

[0010] The first connector consists of an upper connecting part and a lower connecting part. Both the upper and lower connecting parts are provided with mounting holes for bolts. The upper connecting part has an upward-opening U-shaped structure for connecting the inclined beam; the lower connecting part has a ring-shaped structure that surrounds the column for connecting the column.

[0011] Each first connector group includes two identical arc-shaped connecting plates; each connecting plate has an extension arm on each side, and the two extension arms on the same connecting plate are staggered vertically in the horizontal direction. When the two connecting plates are joined together with their arc-shaped openings facing each other, the extension arms on different sides of the two connecting plates are staggered vertically and joined together to form a ring structure that hugs the outer perimeter of the column.

[0012] The second connector consists of two U-shaped parts, one above the other. The bottoms of these two U-shaped parts are connected, with the opening of the upper U-shaped part facing upwards for connecting the crossbeam and the opening of the lower U-shaped part facing downwards for connecting the inclined beam. Each U-shaped part has mounting holes on its sidewall for bolt engagement.

[0013] The mounting hole is a runway-shaped mounting hole.

[0014] The bolts in the fastening assembly are T-bolts. The head of the T-bolt is a parallel polygon, with one set of parallel sides being the long side and the other two sets being the short sides. After the head of the T-bolt is rotated at a certain angle in the mounting groove of the profile, it is engaged in the groove.

[0015] The mounting groove on the profile extends along the length of the main body, and the mounting groove has lateral openings on both sides.

[0016] The mounting groove on the profile has a T-shaped cross-section.

[0017] The connection between the mounting groove on the profile and the main body is a Z-shaped structure. The Z-shaped structure includes a horizontal side and two vertical sides. The first vertical side and the second vertical side are located at the two ends of the horizontal side and extend parallel to each other in the same direction from the two ends of the horizontal side.

[0018] The profile has a cross-section that is quadrilateral, pentagonal, hexagonal, or octagonal; the mounting grooves distributed on the outer periphery of the profile are two, three, or four.

[0019] The beneficial effects of this utility model by adopting the above solution are mainly reflected in the following aspects:

[0020] Firstly, by creating mounting grooves on the surface of the profiles used as columns, diagonal beams, and horizontal beams, direct mounting points are provided for the connectors, eliminating the need for additional slots or complex connection structures. This not only simplifies the assembly process and reduces construction steps but also significantly improves construction efficiency.

[0021] Secondly, the fastening components (including bolts and nuts) securely connect the connectors to the profiles, ensuring the stability and safety of the structure. The bolt heads are positioned within the mounting grooves, effectively preventing loosening and detachment, thus enhancing the stability of the entire support structure. Furthermore, compared to traditional ring-type connectors and fasteners, this invention reduces the number of connectors used, lowering material costs. Simultaneously, the simplified assembly process also reduces labor costs. Attached Figure Description

[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] This utility model provides a roof support structure for a photovoltaic bracket, such as... Figures 2 to 9 As shown, the structure includes a column 2, a diagonal beam 3, and a crossbeam 4. The column 2 is supported between the ground and the roof, the diagonal beam 3 is erected on top of the column 2, and the crossbeam 4 is erected above the diagonal beam 3. The column 2 and the diagonal beam 3 are connected by a first connector 5, and the diagonal beam 3 and the crossbeam 4 are connected by a second connector 6.

[0041] In this design, the key profile 1 used as column 2, diagonal beam 3, and crossbeam 4, such as Figure 2 As shown, the outer surface of its main body 11 is provided with a mounting groove 12 structure. The connecting parts and the profile 1 are fixedly connected by a fastening assembly 7. The fastening assembly 7 includes a bolt 71 and a nut 72. The head of the bolt 71 is limited in the mounting groove 12 of the profile 1, and the shank of the bolt 71 passes through the connecting part and is fastened by the nut 72.

[0042] On profile 1, the design of the mounting groove 12 is not only key to reducing the number of parts required for connection, but also greatly improves the efficiency and flexibility of on-site assembly. For example... Figure 3 and Figure 4 As shown, the mounting groove 12 extends along the length of the main body 11 of the profile 1, providing a wide and flexible sliding space for the bolt 71. This allows the bolt 71 to move freely along its length within the mounting groove 12, thus providing as many mounting point options as possible and ensuring that the bolt 71 can achieve a stable fixing effect in each ideal position. Furthermore, lateral openings are provided on both sides of the mounting groove 12 to facilitate the bolt 71's entry and exit from the mounting groove 12. The cross-section of the mounting groove 12 is T-shaped to prevent the head of the bolt 71 from axially dislodging from the mounting groove 12.

[0043] To improve the stability of the connection, this solution uses T-bolts 71, such as... Figure 6 and Figure 7As shown, the head of the T-bolt 71 is a parallelepiped, with one set of parallel sides being the long sides and the other two sets being the short sides. The T-bolt 71 is engaged with the mounting groove 12 on the inclined beam 3 as follows: the head of the T-bolt 71 is slid into the side opening of the mounting groove 12, and then rotated at a certain angle so that its head is locked in the groove of the mounting groove 12. In this way, the T-bolt 71 can no longer slide in the mounting groove 12.

[0044] Regarding the connectors, both the first connector 5 and the second connector 6 have mounting holes 8 that mate with bolts 71. The bolts 71 mate with the mounting grooves 12 and mounting holes 8 at corresponding positions to achieve connection and fixation at each point, thereby connecting and fixing the column 2, the diagonal beam 3, and the crossbeam 4.

[0045] like Figure 7 As shown, the first connecting part 5 is composed of an upper connecting part and a lower connecting part. Both the upper connecting part and the lower connecting part are provided with mounting holes 8 that cooperate with bolts 71. The upper connecting part has an upward-opening U-shaped structure for connecting the inclined beam 3; the lower connecting part has an annular structure that surrounds the column 2 for connecting the column 2.

[0046] To facilitate production, processing, and assembly, this design further improves the structure of the first connector 5. For example... Figure 7 and Figure 8 As shown, each set of first connecting parts 5 consists of two identical connecting plates 51. These two connecting plates 51 are joined together in a left-right splicing manner, encircling the outer perimeter of the column 2, thus forming a connection structure that is both stable and easy to assemble. Specifically, each connecting plate 51 adopts an arc-shaped structure design, which allows it to better conform to the curved surface of the column 2, increasing the stability and tightness of the connection. On both sides of each connecting plate 51, there is an extension arm 52. The two extension arms 52 on the same connecting plate 51 are staggered in the horizontal direction, that is, one extension arm 52 is on top and the other extension arm 52 is on the bottom. In this way, when the two connecting plates 51 are spliced ​​together with their arc-shaped openings facing each other, the extension arms 52 on the different sides of the two connecting plates 51 are staggered vertically, forming a ring structure.

[0047] like Figure 9As shown, the second connecting member 6 consists of two U-shaped parts, upper and lower, connected at their bottoms, which can also be considered as sharing a common bottom. The upper U-shaped part 61 opens upwards to connect to the crossbeam 4, while the lower U-shaped part 62 opens downwards to connect to the inclined beam 3. Each U-shaped part has mounting holes 8 on its sidewalls for engagement with bolts 71. During assembly, the upper connecting part of the first connecting member 5 and the lower U-shaped part 62 of the second connecting member 6 together enclose the outer periphery of the inclined beam 3, with the second connecting member 6 inside (closer to the inclined beam 3) and the first connecting member 5 outside. In other words, during assembly, the mounting holes 8 on the upper connecting part of the first connecting member 5 correspond to the mounting holes 8 on the lower U-shaped part 62 of the second connecting member 6, forming a one-to-one corresponding hole set. Each corresponding set of mounting holes 8 is fastened together by a set of bolts 71 and nuts 72. This design not only ensures the accuracy of installation but also significantly improves the overall structural strength and stability.

[0048] The connector described in this case has a runway-shaped mounting hole 8, as shown in the reference. Figure 8 and Figure 9 The design of the runway-shaped mounting holes 8 allows for a degree of fine-tuning during installation, ensuring precise alignment and tight fit between the inclined beam 3 and the connector.

[0049] As a further improvement to the structure, the connection between the mounting groove 12 on the crossbeam 4 and the main body 11 is a Z-shaped structure 13. Specifically, as... Figure 4 and Figure 5 As shown, the Z-shaped structure 13 includes a horizontal side 131 and two vertical sides. The first vertical side 132 and the second vertical side 133 are located at both ends of the horizontal side 131 and extend parallel to each other in the same direction. During processing, these components are integrally formed with the main body 11. Compared with traditional sharp bending angles, this Z-shaped transition structure can effectively disperse stress and significantly reduce stress concentration, thus making the stress distribution at the connection more uniform and reasonable. This design not only significantly improves the fatigue resistance of the profile 1 during use and enhances the structural stability, but also greatly improves the overall load-bearing capacity and reliability of the photovoltaic support profile 1, providing a guarantee for the safe and efficient operation of the photovoltaic support.

[0050] The main body 11 of the profile 1 is typically designed as a hollow structure, but this design is not an absolute requirement. It can be flexibly adjusted according to actual application needs. The main advantage of using a hollow main body 11 structure is that it significantly reduces the overall weight, thereby improving the handling and installation efficiency of the photovoltaic bracket; at the same time, the hollow design can effectively improve material utilization, reduce costs, and make the manufacturing of the photovoltaic bracket more economical and efficient. Furthermore, the hollow structure provides greater flexibility to the profile 1, facilitating plug-in assembly with components such as bases and connectors.

[0051] Regarding the shape of the profile section 1, we offer a variety of designs, including but not limited to quadrilateral, pentagonal, hexagonal, and octagonal options, such as... Figure 10 As shown, the selection of these shapes is entirely based on actual assembly requirements and application scenarios. This solution does not impose specific limitations on them to ensure maximum flexibility and adaptability. In this solution, as needed, profile 1 with an octagonal cross-section is selected as column 2, and profile 1 with a rectangular cross-section is selected as inclined beam 3 and crossbeam 4.

[0052] Regarding the number of mounting grooves 12 distributed around the outer periphery of the main body 11 of profile 1, such as Figure 10 As shown, there are, but are not limited to, two, three, or four mounting slots 12, the specific number of which depends on the assembly requirements and application scenario. In this solution, the column 2 has four mounting slots 12, the inclined beam 3 and the crossbeam 4 each have three mounting slots 12, the first connecting member 5 has mounting holes 8 corresponding to the mounting slots 12 on the column 2 and the inclined beam 3, and the second connecting member 6 has mounting holes 8 corresponding to the mounting slots 12 on the inclined beam 3 and the crossbeam.

[0053] The assembly method of the roof support structure of the photovoltaic bracket of this utility model is as follows:

[0054] refer to Figure 2 The pre-fixed column 2 is usually fixed to the base, but it can also be fixed directly to the ground. The specific installation method is not limited in this case, so as to adapt to the needs of different scenarios.

[0055] First, install the first connector 5 on the column 2 and fix it with T-bolts 71 and nuts 72 through the mounting groove 12 of the profile 1. Then, embed the inclined beam 3 into the upper connecting part of the first connector 5. Next, embed the lower U-shaped part 62 of the second connector 6 into the inclined beam 3 and fix it with T-bolts 71 and nuts 72. Finally, place the crossbeam 4 into the U-shaped part 61 of the second connector 6 and fix it with T-bolts 71 and nuts 72 through the mounting groove 12 of the profile 1.

The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components. Furthermore, the front, back, left, and right directions involved in this embodiment are only as a reference and do not represent the actual orientation in practical application.
