Description

Technical Field

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

[0002] Currently, the photovoltaic support brackets are L-shaped, only one side of which is attached to the corrugated steel roof, making them prone to wobbling and spinning, and unreliable. Similarly, the connection to the uprights is only one side, resulting in an unbalanced overall structure and uneven stress distribution on the brackets. Furthermore, the current uprights are made of square aluminum, requiring an angle aluminum connector to connect the uprights to the crossbeams, and this connection involves drilling an eccentric hole, leading to a complex structure and uneven stress distribution. Figures 1 to 4 As shown. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a rooftop photovoltaic support structure.

[0004] This utility model is implemented using the following method: a rooftop photovoltaic elevated support bracket includes a base, with symmetrical legs on both sides of the lower end of the base, and symmetrical connecting arms on both sides of the upper surface of the base, forming a U-shaped frame; a column is connected to the base, the column includes a column body, the bottom of the column body is inserted into the two connecting arms of the base, and a wing plate is provided on the surface of the column body adjacent to the connecting arms, the wing plate being connected to a crossbeam.

[0005] Preferably, the two legs are fixed to the lower end of the base in a figure-eight shape, matching the shape of the corrugated steel sheet.

[0006] Preferably, the surface of the wing plate that contacts the crossbeam is flush with the surface of the column body that contacts the crossbeam.

[0007] Preferably, the wing plate is connected to the crossbeam by a first bolt.

[0008] Preferably, the cross-section of the beam is rectangular, and each of the two adjacent sides of the beam is provided with a first opening groove, into which the first bolt passes.

[0009] Preferably, the cross-section of the first opening groove is C-shaped.

[0010] Preferably, at least one second bolt passes through both connecting arms, and the second bolt also passes through the column body sandwiched between the two connecting arms.

[0011] Preferably, the surface of the column body facing away from the surface in contact with the crossbeam is provided with a second opening groove, through which the second bolt passes.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a rooftop photovoltaic elevated support bracket, which, compared with the prior art, has at least the following technical effects: 1. The symmetrical support leg design increases the contact area with the corrugated steel roof, ensuring a stable and reliable three-sided fit with the corrugated steel roof, preventing rotation and solving the swaying problem caused by single-sided fitting; the U-shaped frame structure allows the column body to be held in the middle by the connecting arms on both sides, with the center of gravity in the center, resulting in uniform force distribution and eliminating structural eccentricity; the side wing plates directly connect to the crossbeams, replacing the original angle aluminum connectors, reducing one angle aluminum connector transition, increasing structural stability, and simplifying the structural hierarchy. 2. The inclination angle of the support legs is V-shaped, matching the corrugated outline of the corrugated steel roof, enhancing the contact surface fit. 3. The wing plates are flush with the contact surface of the column, ensuring stable contact between the column and the connecting arm, improving the contact quality of the connection interface, and reducing vibration and noise. 4. The column and crossbeam can be directly locked together with the first bolt, saving angle aluminum connectors and helping to reduce the production cost of the photovoltaic support bracket. 5. Currently, crossbeams are either slotted or four-slotted. Slotted crossbeams require corresponding slots for connection during installation, making installation cumbersome. Four-slotted crossbeams only require two slots to be used, resulting in higher weight per meter. This utility model uses a non-standard square aluminum crossbeam with only two slots for connection. The external hexagonal bolts are directly connected to the column by locking into the slots (no need for actual slots), significantly reducing weight per meter compared to four-slotted crossbeams. 6. The first slot has a C-shaped cross-section, facilitating the locking and fixing of the first bolt, thus making it easier to fix the crossbeam to the column. 7. The through-type second bolt simultaneously constrains the connecting arm and the column body, eliminating the risk of relative rotation; the bolt is subjected to shear force instead of the original unilateral tensile force, improving the joint strength. 8. The second slot on the column enhances the bending strength of the second column and provides positioning for the installation of the second bolt, facilitating the alignment of the column and the base.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 5 to 10 A rooftop photovoltaic (PV) support structure includes a base 1 with symmetrical legs 11 on both sides of its lower end and symmetrical connecting arms 12 on both sides of its upper surface, forming a U-shaped frame. A column is connected to the base 1, and each column includes a column body 2. The bottom of the column body 2 is inserted into the two connecting arms 12 of the base 1. A wing plate 21 is provided on the surface of the column body 2 adjacent to the connecting arms 12, and the wing plate 21 is connected to a crossbeam 3. The symmetrical leg 11 design increases the contact area with the corrugated steel roof, ensuring a stable and secure fit on three sides of the bottom, preventing rotation and solving the swaying problem caused by single-sided fitting. The U-shaped frame structure allows the column body 2 to be held in the middle by the connecting arms 12, with the center of gravity in the center, resulting in uniform force distribution and eliminating structural eccentricity. The wing plates 21 directly connect to the crossbeam 3, replacing the original angle aluminum connectors, reducing the need for one angle aluminum connector, increasing structural stability, and simplifying the structural hierarchy.

[0026] Please see Figures 5 to 8 , Figure 10 Preferably, the two support legs 11 are fixed to the lower end of the base 1 in a V-shape, matching the shape of the corrugated steel sheet. The V-shaped inclination angle of the support legs 11 matches the corrugated outline of the corrugated steel sheet, enhancing the fit of the contact surface.

[0027] Please see Figures 5 to 8 , Figure 10Preferably, the surfaces of the wing plate 21 and the crossbeam 3 that contact each other are flush with the surfaces of the column body 2 and the crossbeam 3. The flushness of the wing plate 21 with the column contact surface ensures smooth contact between the column and the connecting arm 12, improves the contact quality of the connection interface, and reduces vibration and noise. Of course, the wing plate 21 only needs to be positioned between the two surfaces that contact the connecting arm 12, without exceeding this range.

[0028] Please see Figures 5 to 8 , Figure 10 Preferably, the wing plate 21 is connected to the crossbeam 3 by a first bolt 4. The column and the crossbeam 3 can be directly locked together by the first bolt 4, saving on angle aluminum connectors and helping to reduce the production cost of the photovoltaic bracket.

[0029] Please see Figure 5 , Figure 6 , Figures 9 to 10 Preferably, the cross-section of the crossbeam 3 is rectangular, and each of the two adjacent sides of the crossbeam 3 is provided with a first opening slot 31, into which the first bolt 4 passes. Currently, the crossbeam 3 is either a slotted crossbeam 3 with a locking block or a four-slot crossbeam 3. The slotted crossbeam 3 with a locking block requires corresponding locking blocks for connection during installation, which is more troublesome. The four-slot crossbeam 3 actually only requires two slots to be used, resulting in a higher weight per meter. The irregular square aluminum of this utility model only has two slots for connection directions, and the external hexagonal bolts are directly connected to the column by locking the slots (without the need to use locking blocks), which greatly reduces the weight per meter compared to the four-slot crossbeam 3.

[0030] Please see Figure 5 , Figure 6 , Figures 9 to 10 Preferably, the cross-section of the first opening groove 31 is C-shaped. The C-shaped cross-section of the first opening groove 31 facilitates the locking and fixing of the first bolt 4, so as to facilitate the fixing of the crossbeam 3 to the column.

[0031] Please see Figures 5 to 8 , Figure 10 Preferably, at least one second bolt 5 passes through both connecting arms 12, and the second bolt 5 also passes through the column body 2 sandwiched between the two connecting arms 12. The through-bolt 5 simultaneously constrains the connecting arms 12 and the column body 2, eliminating the risk of relative rotation; the bolt is subjected to shear force instead of the original unilateral tensile force, improving the joint strength.

[0032] Please see Figures 5 to 8 , Figure 10 Preferably, the surface of the column body 2 facing away from the surface in contact with the crossbeam 3 is provided with a second opening groove 22, through which the second bolt 5 passes. The second opening groove 22 on the column enhances the bending strength of the second column and provides positioning for the installation of the second bolt, facilitating the alignment of the column and the base 1.

[0033] Please see Figures 5 to 8 Preferably, the column has a hollow structure, and the hollow part can provide space for the third bolt 8 connecting the base 1 and the corrugated steel roof 6.

[0034] The working principle of this utility model is as follows:

[0035] First, align the support legs 11 at the bottom of the base 1 and three sides of the lower surface of the base 1 with the corrugated steel roof 6. Then, secure the base 1 to the corrugated steel roof 6 with bolts. Next, align and insert the column body 2 between the two connecting arms 12 (the second opening slot 22 needs to be aligned with one side of the connecting arm 12). Then, lock the second bolt 5 between the two connecting arms 12, and the second bolt 5 should pass through the second opening slot 22. Repeat this process to complete the assembly of multiple bases 1, columns, etc., with the corrugated steel roof 6. Then, lock the first bolt 4 between the top of the two wing plates 21 of each column and the first opening slot 31 on one side of the crossbeam 3 to fix the crossbeam 3 to the top of the column. This completes the assembly of the entire photovoltaic frame. After that, the photovoltaic panels 7 can be installed on the crossbeam 3.
