Technical Field
[0001] The utility model relates to the technical field of flexible brackets, in particular to a herringbone end column flexible bracket. Background Art
[0002] Photovoltaic brackets are increasingly used in scenes with complex terrain, such as hillsides, swamps, and water treatment plants. In such scenes, the span between the columns of the photovoltaic brackets needs to be greatly increased so that the photovoltaic brackets can meet different terrain requirements and can still stably support photovoltaic modules in complex terrain environments.
[0003] With the widespread application of photovoltaic flexible support systems, especially the application of large-span flexible cable structures, the design of the fixed end brackets on both sides of the bracket is particularly important. When the fixed end is subjected to unreasonable force, it will increase its own displacement and reduce the cumulative displacement of the cable span, eventually resulting in a smaller span.

[0006] Optionally, piles are provided at the bottom of the four bases, the bottoms of the four piles extend correspondingly to the inside of the concrete foundation, and reinforced squirrel cages are provided inside the four piles.
[0007] Optionally, an upper force-bearing cable is horizontally arranged between the tops of the two steel columns, and a lower force-bearing cable is arranged between the tops of the two steel columns.
[0008] Optionally, the lower force-bearing cable is concave, and steel strands are fixed to the tops of the two steel columns. One ends of the two steel strands extend vertically downward and are fixed on the diagonal bracing columns.
[0009] Optionally, a wind-resistant cable is fixed between the outer surfaces of the two steel columns near the top edge, the wind-resistant cable is upwardly convex, and the wind-resistant cable and the lower force-bearing cable are interlaced with each other.
[0010] Optionally, the convex top of the wind-resistant cable is located in the middle and connected to the upper force-bearing cable, and a support rod is provided on the convex top of the wind-resistant cable, and one end of the support rod is connected to the concave part of the lower force-bearing cable.

[0022] The effect achieved by the entire embodiment 1 is that by changing the form of the end bracket to a herringbone shape, the force is made more reasonable and the deflection in the mid-span of the cable can be reduced. Due to the change in the form of the end bracket, the displacement of the column top can be reduced, and at the same time, the deflection in the mid-span of the cable can be reduced, making the assembly safer. When installing the herringbone end bracket and the cable structure on site, the prestressing needs to be completed according to the design. The structural force transmission is clear, the force transmission path is simple, and the mid-span deflection can be reduced.
[0023] Embodiment 2, as Figure 1-2 As shown, piles 2 are provided at the bottom of the four bases 3, and the bottoms of the four piles 2 extend to the inside of the concrete foundation 1 accordingly. A steel cage 4 is provided inside the four piles 2. An upper force-bearing cable 7 is horizontally provided between the tops of the two steel columns 6, and a lower force-bearing cable 10 is provided between the tops of the two steel columns 6. The lower force-bearing cable 10 is concave. Steel strands 11 are fixed to the tops of the two steel columns 6. One ends of the two steel strands 11 extend vertically downward and are fixed on the diagonal bracing column 5. A wind-resistant cable 8 is fixed between the outer surfaces of the two steel columns 6 near the top edge. The wind-resistant cable 8 is convex, and the wind-resistant cable 8 and the lower force-bearing cable 10 are interlaced with each other. The convex top of the wind-resistant cable 8 is located in the middle and is connected to the upper force-bearing cable 7. A support rod 9 is provided at the convex top of the wind-resistant cable 8, and one end of the support rod 9 is connected to the concave part of the lower force-bearing cable 10.
[0024] The effect achieved by the entire embodiment 2 is that during the installation process, the wind-resistant cable 8 and the lower force-bearing cable 10 need to be staggered with each other so that the wind-resistant cable 8 and the lower force-bearing cable 10 form a whole, and the convex top of the wind-resistant cable 8 is located in the middle and connected with the upper force-bearing cable 7, and then the convex top of the wind-resistant cable 8 and the concave part of the lower force-bearing cable 10 are connected by the support rod 9, so that the middle gap with a larger part can be supported by the support rod 9, thereby ensuring the stability of the middle part.
[0025] Working principle: By changing the form of the end bracket to a herringbone shape, the force is more reasonable and the deflection in the mid-span of the cable can be reduced. Due to the change in the form of the end bracket, the displacement of the column top can be reduced, and the deflection in the mid-span of the cable can be reduced, making the assembly safer. When installing the herringbone end bracket and the cable structure on site, the prestressing needs to be completed according to the design. The structural force transmission is clear and the force transmission path is simple, which can reduce the deflection in the mid-span. During the installation process, the wind-resistant cable 8 and the lower force-bearing cable 10 need to be staggered with each other so that the wind-resistant cable 8 and the lower force-bearing cable 10 form a whole, and the convex top of the wind-resistant cable 8 is located in the middle and connected to the upper force-bearing cable 7. Then the convex top of the wind-resistant cable 8 and the concave part of the lower force-bearing cable 10 are connected by the strut 9, so that the middle gap with a larger part can be supported by the strut 9, thereby ensuring the stability of the middle part.
