Description

Technical Field

[0001] This utility model relates to the field of photovoltaic carport components technology, and more specifically, to a column assembly structure applied to photovoltaic carports. Background Technology

[0002] In the field of steel structures and photovoltaic carports, the columns, as the main supporting structure, directly affect the overall stability, construction efficiency, and long-term performance through their connection method. Traditionally, columns are mostly connected using on-site full welds, meaning the columns are directly welded to the foundation structure on-site. While welding technology is mature, it presents the following significant problems in practical applications:

[0003] 1. Unstable on-site welding quality

[0004] Welding quality is affected by multiple factors, including the working environment (such as outdoor wind, sand, and humidity), the welder's skill level, and the condition of the equipment. Under open-air construction conditions, welds are easily affected by environmental disturbances, leading to defects such as porosity, slag inclusions, and lack of fusion, which in turn reduces the strength of the joint. In addition, the heat-affected zone of welding may cause changes in material properties, such as grain coarsening or residual stress concentration, which may lead to microcracks after long-term use, affecting structural safety.

[0005] 2. High secondary processing costs

[0006] After welding is completed, subsequent processes such as weld grinding and anti-corrosion treatment (such as painting or hot-dip galvanizing) are usually required. If the weld is severely deformed or misaligned, rework and correction are necessary, which will increase labor, material and time costs.

[0007] 3. Low installation efficiency and poor flexibility

[0008] Welding requires specialized equipment (such as welding machines and gas protection devices) and certified welders, resulting in long construction cycles and the inability to quickly disassemble and reassemble. For scenarios requiring adjustments to height or angle (such as optimizing the tilt angle of photovoltaic panels), the welded structure is difficult to modify. Forcibly cutting and reassembling it would damage the original anti-corrosion layer and weaken the structural strength. Utility Model Content

[0009] In order to overcome the problems of unstable quality, low construction efficiency, high secondary processing costs and lack of flexibility in the existing on-site welding and installation of columns, this utility model provides a column assembly structure for photovoltaic carports.

[0010] The technical solution of this utility model is as follows:

[0031] It should be noted that in the field of steel structures and photovoltaic carports, the columns, as the main supporting structure, directly affect the overall stability, construction efficiency, and long-term performance through their connection method. Traditionally, columns are mostly connected using on-site full-weld joints, meaning the columns are directly welded to the foundation structure on-site. While welding technology is mature, it presents the following significant problems in practical applications:

[0032] 1. Unstable on-site welding quality

[0033] Welding quality is affected by multiple factors, including the working environment (such as outdoor wind, sand, and humidity), the welder's skill level, and the condition of the equipment. Under open-air construction conditions, welds are easily affected by environmental disturbances, leading to defects such as porosity, slag inclusions, and lack of fusion, which in turn reduces the strength of the joint. In addition, the heat-affected zone of welding may cause changes in material properties, such as grain coarsening or residual stress concentration, which may lead to microcracks after long-term use, affecting structural safety.

[0034] 2. High secondary processing costs

[0035] After welding is completed, subsequent processes such as weld grinding and anti-corrosion treatment (such as painting or hot-dip galvanizing) are usually required. If the weld is severely deformed or misaligned, rework and correction are necessary, which will increase labor, material and time costs.

[0036] 3. Low installation efficiency and poor flexibility

[0037] Welding requires specialized equipment (such as welding machines and gas protection devices) and certified welders, resulting in long construction cycles and the inability to quickly disassemble and reassemble. For scenarios requiring adjustments to height or angle (such as optimizing the tilt angle of photovoltaic panels), the welded structure is difficult to modify. Forcibly cutting and reassembling it would damage the original anti-corrosion layer and weaken the structural strength.

[0038] like Figures 1-4 As shown, this embodiment provides a column assembly structure for photovoltaic carports. The column assembly 10 and pre-embedded screws 31 are connected by fasteners to achieve non-welding assembly, replacing traditional welding processes. This eliminates quality risks such as weld porosity and cracks caused by harsh on-site welding environments and varying welder skill levels, ensuring stable and reliable structural strength at the connection points. Using standardized fastener connections, no professional welding equipment or certified welders are required; ordinary construction workers can quickly complete the installation, significantly reducing on-site construction intensity and difficulty, thereby improving installation efficiency. Furthermore, the fasteners facilitate easy assembly and disassembly when adjustments to height or angle are needed.

[0039] Specifically, the column assembly structure applied to the photovoltaic carport includes a column assembly 10 and a connecting assembly 20. The column assembly 10 is connected to the foundation structure 30 through a pre-embedded screw 31. The connecting assembly 20 includes multiple fasteners. The column assembly 10 is connected to the pre-embedded screw 31 through the fasteners to achieve non-welding assembly.

[0040] In one embodiment, the column assembly 10 includes a column unit 11 and a flange 12, the column unit 11 and the flange 12 being connected.

[0041] The column assembly 10 also includes several reinforcing ribs 13, each rib being triangular in shape and evenly distributed at the connection between the column unit 11 and the flange 12. The rigid connection between the flange 12 and the column unit 11, combined with the reinforcing ribs 13, improves the overall resistance to lateral forces. The triangular design of the reinforcing ribs 13 optimizes the transmission of force flow, effectively dispersing stress concentrations caused by wind and snow loads. The evenly distributed triangular reinforcing ribs 13 at the connection between the column unit 11 and the flange 12 form a stable mechanical support structure, enhancing the bending strength of the connection area.

[0042] It should be noted that the connection between the column unit 11 and the flange 12, as well as the connection between the column assembly 10 and the reinforcing rib 13, are all completed in the factory to avoid quality fluctuations in on-site welding, reduce on-site workload, and improve work efficiency.

[0043] The flange 12 is provided with a number of reserved holes 121, and the reserved holes 121 correspond one-to-one with the positions of the embedded screws 31, which can improve the positioning accuracy when installing the pole assembly and the embedded screws 31.

[0044] An adjusting shim 22 is provided in the reserved hole 121 for fine-tuning the verticality of the column assembly 10. The adjusting shim 22 ensures the installation accuracy of the column and adapts to unevenness of the foundation structure 30.

[0045] In one embodiment, the pre-embedded screw 31 is L-shaped, and the bending angle of the pre-embedded screw 31 is placed within the base structure 30 to ensure that the pre-embedded screw 31 is stably installed within the base structure 30 and to prevent it from loosening.

[0046] In one embodiment, the foundation structure 30 is a concrete base, and the pre-embedded screw 31 is pre-embedded in the base before the concrete is poured, with the top end of the pre-embedded screw 31 protruding 50-100mm above the surface of the base. This design, where the pre-embedded screw 31 protrudes 50-100mm above the base, provides ample operating space and improves installation efficiency.

[0047] The foundation structure 30 is further provided with an embedded plate 32, and the orthographic projection of the column assembly 10 is located within the orthographic projection of the embedded plate 32. The design of the embedded plate 32 expands the load distribution area of ​​the column assembly 10, and optimizes the force transmission path to a three-level transmission of "column assembly 10 → embedded plate 32 → base", avoiding local damage to the base caused by stress concentration. Specifically, the force of the column assembly 10 is transmitted to the embedded plate 32, and after being evenly distributed on the embedded plate 32, it is transmitted to the base, preventing excessive stress in one place from causing damage to the base.

[0048] The embedded plate 32 is provided with a plurality of embedded through holes, and the positions of the embedded through holes correspond one-to-one with the positions of the embedded screws 31. The embedded plate 32 is placed on the base surface during the concrete pouring to provide a reference plane for the installation of the column assembly 10.

[0049] In one embodiment, the fastener includes a nut 21 and a washer 22. The nut 21 and the pre-embedded screw 31 cooperate to lock the column assembly 10, ensuring that the tensile strength of the connection part is high enough, so that the connection node remains stable under long-term vibration environment and the risk of loosening is low.

[0050] In one embodiment, the column unit 11 is a long strip of steel with an I-shaped cross-section. The I-shaped cross-section of the column unit 11 increases its bending section modulus compared to a rectangular cross-section, significantly enhancing its wind load resistance.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0052] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
