[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The core of this utility model is to provide a prefabricated steel structure carport that does not require welding during on-site assembly, can be quickly assembled by a small number of workers, and also improves the stability of the carport.

[0039] It should be noted that in this embodiment, "row" refers to an arrangement along the left-right direction (i.e., the width direction of the carport), and "column" refers to an arrangement along the front-back direction (i.e., the length direction of the carport). Furthermore, relational terms such as "first" and "second" are merely used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0040] Please refer to Figure 1This application provides a prefabricated steel structure carport, including a frame body and a roof. The frame body includes columns 1, main beams 2, support beams 3 and purlins 4. The bottom end of the column 1 is provided with a base 5 for detachable connection with the foundation 6. Multiple columns 1 are distributed in multiple rows and two columns. The support beams 3 can be detachably connected between the two opposing sides of the top of the two columns 1 in each row. The top of the multiple columns 1 in each column can be detachably connected to the main beams 2. Multiple purlins 4 can be detachably connected between the tops of the two main beams 2 at intervals. The roof is detachably mounted on the multiple purlins 4.

[0041] The main frame serves as the primary supporting structure for the entire carport, and its structural strength determines the carport's stability. The main frame is preferably made of steel, which, compared to aluminum alloy carports, offers greater load-bearing capacity, better impact resistance, and effectively reduces the risk of collapse under extreme weather conditions.

[0042] The main frame consists of columns 1, main beams 2, support beams 3, and purlins 4. These components are preferably thin-walled steel pipes, which not only have high load-bearing capacity but are also lightweight, reducing the overall weight of the carport. Multiple columns 1 are arranged in two rows, with support beams 3 between the tops of the two columns 1 in each row, forming a stable truss structure that effectively resists lateral wind loads. Furthermore, the tops of the multiple columns 1 in each row are all supported by main beams 2, with multiple purlins 4 spaced between the two main beams 2. This effectively improves the lateral stiffness of the frame, further enhancing its resistance to lateral wind loads, thus making the carport more stable and reducing the risk of collapse in extreme weather conditions.

[0043] Furthermore, the connections between column 1 and main beam 2, support beam 3, and main beam 2 and purlin 4 are all detachable. It's easy to understand that detachable connections between components (such as threaded connections and snap-fit ​​connections) differ from welding, allowing components to be separated after assembly. In this way, these components can be standardized and manufactured in the factory, eliminating the need for welding operations and specialized construction teams on-site. A small number of workers can complete the assembly on-site with just tools, thereby improving assembly efficiency and saving labor costs.

[0044] Based on the above embodiments, as a further preferred option, please refer to... Figure 1 , Figure 5 , Figure 9 and Figure 10 The base 5 is made of steel plate with multiple bolt holes. These bolt holes are used to pass through pre-embedded bolts 7 on the foundation 6 and are fastened together, enabling a detachable connection between the base 5 and the foundation 6. This method facilitates the installation of the base 5 and also enhances the connection strength between the base 5 and the foundation 6, improving the structural stability of the column 1.

[0045] Based on the above embodiments, as a further preferred option, the foundation 6 can be an existing concrete surface with a thickness of 20cm or more, on which expansion bolts or chemical bolts are installed; or, the foundation 6 can also be a cast-in-place concrete structure, which can be cast as an independent foundation (suitable for ordinary soil, low cost, and simple construction. It requires pre-embedded rebar and post-installed chemical bolts or expansion bolts), a strip foundation (suitable for soft soil or scenarios where loads need to be distributed), or a pile foundation (suitable for soft soil, high groundwater level, or high wind pressure areas).

[0046] Ground unevenness treatment: If the ground is uneven, it must be adjusted during the construction of foundation 6. A laser level must be used to ensure that foundation 6 is level. Concrete foundation requirements: Concrete strength grade ≥ C25, curing period ≥ 7 days. Anchor bolts can be pre-embedded in the cast-in-place concrete base 5, with a pre-embedded bolt depth ≥ 120mm.

[0047] The foundation 6 adopts the above-mentioned concrete ground + bolt structure. After the base 5 at the bottom of the column 1 is connected to the bolt, the foundation 6 can firmly support the column 1 and ensure the structural stability of the column 1.

[0048] It should be noted that the space formed between the two columns 1 is used for parking vehicles. In one specific embodiment, the main specification of the spacing between the two columns 1 in a single parking space is 3000mm; the main specification of the spacing between the two columns 1 in a double parking space is 5200mm.

[0049] Furthermore, the number of columns 1 in each column depends on the number of rows of columns 1. The more rows there are, the more columns 1 there are, and the greater the stability of the main frame. Of course, in practical applications, to simplify the carport structure and save costs, multiple columns 1 can be distributed in two rows and two columns. In this case, the main specification for the spacing between the two rows of columns 1 for a single parking space or a double parking space can be 4200mm.

[0050] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The top of the column 1 is provided with a first U-shaped plate 8 with an open end opposite to it. The two side plates of the first U-shaped plate 8 are respectively connected to the two sides of the main beam 2 by the first fastener. The top side of the column 1 is provided with a second U-shaped plate 9 with an open end opposite to it. The two side plates of the second U-shaped plate 9 are respectively connected to the two sides of the end of the support beam 3 by the second fastener. The top of the main beam 2 is provided with a third U-shaped plate 10 with an open end opposite to it. The two side plates of the third U-shaped plate 10 are respectively connected to the two sides of the end of the purlin 4 by the third fastener.

[0051] In this embodiment, during factory production, a first U-shaped plate 8 is welded to the top of the column 1. The open end of the first U-shaped plate 8 must face away from the column 1 to facilitate the insertion of the end of the main beam 2 into the first U-shaped plate 8. Furthermore, each side plate of the first U-shaped plate 8 has at least one bolt hole, and correspondingly, each opposite side of the end of the main beam 2 also has at least one bolt hole. This avoids welding operations during on-site installation. Workers use tools to fasten the first U-shaped plate 8 to the end of the main beam 2 with first fasteners (e.g., bolts), thus quickly completing the assembly of the main beam 2.

[0052] In addition, a second U-shaped plate 9 is welded to one side of the top of the column 1. The open end of the second U-shaped plate 9 must face away from the side of the column 1 to facilitate the insertion of the end of the support beam 3 into the second U-shaped plate 9. Each side of the second U-shaped plate 9 has at least one bolt hole, and correspondingly, each side of the end of the support beam 3 also has at least one bolt hole. This avoids welding during on-site installation; workers use tools (such as bolts) to fasten the second U-shaped plate 9 to the end of the support beam 3, thus quickly completing the assembly of the support beam 3.

[0053] A third U-shaped plate 10 is also welded to the top of the main beam 2. The number of third U-shaped plates 10 is the same as the number of purlins 4. The open end of the third U-shaped plate 10 must face away from the main beam 2 to facilitate the insertion of the end of the purlin 4 into the third U-shaped plate 10. Each side of the third U-shaped plate 10 has at least one bolt hole, and correspondingly, each side of the end of the purlin 4 also has at least one bolt hole. This avoids welding during on-site installation. Workers use tools to fasten the third U-shaped plate 10 to the end of the purlin 4 with third fasteners (such as bolts), thus quickly completing the assembly of the purlin 4.

[0054] In this way, all components in the main frame are detachably connected by U-shaped plates and bolts. The U-shaped plates have openings on both sides, allowing the components to be assembled to move flexibly to accommodate components of different lengths. In addition, the U-shaped plates also have an opening at one end, making it easy to insert the components to be assembled, thus improving the flexibility of assembly. Furthermore, the use of bolted connections can form rigid nodes, which can make the assembled main frame more stable.

[0055] Based on the above embodiments, as a further preferred option, please refer to... Figure 9 The height of the multiple rows of columns 1 gradually decreases from front to back, and the two columns 1 in each row are of the same height, so that the multiple purlins 4 form a sloping roof that is higher in the front and lower in the back. In this way, the sloping roof can be fitted with a roof cover to form a sloping canopy roof, which can reduce water accumulation on the canopy roof through automatic drainage, thereby reducing the cost of waterproofing construction.

[0056] In one specific embodiment, please refer to Figure 9 and Figure 10For a carport with two rows and two columns 1, the front height H ranges from 2.5m to 4m, with an optimal height of 3.5m; the rear height h ranges from 2m to 3m, with an optimal height of 2.5m; the distance between the front and rear columns 1 is 3m to 5m, with an optimal distance of 4m. The width b of the column 1 for a single-carport carport is 2.5m to 3.5m, with an optimal width of 3m; the width B of the single-carport roof (i.e., photovoltaic module 12) is 3m to 4m, with an optimal width of 3.5m. For a double-carport carport, the width b of the column 1 is 5m to 6m, with an optimal width of 5.2m; the width B of the double-carport roof (i.e., photovoltaic module 12) is 5m to 7m, with an optimal width of 6m.

[0057] Based on the above embodiments, as a further preferred option, please refer to... Figure 11 and Figure 12 The top cover is set as a photovoltaic module 12, which includes multiple photovoltaic panels 121, which are arranged and laid on the inclined top.

[0058] The photovoltaic module 12 can convert light energy into electrical energy. The photovoltaic module 12 replaces the conventional canopy panel and is placed on the top of the main frame. It can not only provide rain and sun protection for the vehicle, but also save energy by absorbing sunlight and converting it into electrical energy to power the vehicle.

[0059] Based on the above embodiments, as a further preferred option, please refer to... Figure 8 The rear end of the lowest purlin 4 is detachably provided with a water guide groove 11, and the opening of the water guide groove 11 is not higher than the lowest purlin 4.

[0060] It should be noted that in this embodiment, the front-back direction refers to the direction in which the main beam 2 extends and is placed, and the multiple purlins 4 connecting the two main beams 2 are arranged at intervals along the front-back direction.

[0061] Thus, the height of the multiple rows of columns 1 gradually decreases from front to back. That is, the height of each column 1 gradually decreases from front to back, and consequently, the height of the two main beams 2 also gradually decreases from front to back. Correspondingly, the height of the multiple rows of purlins 4 also gradually decreases from front to back. The rear end of the lowest purlin 4 is connected to the drainage channel 11 by bolts. Water on the roof can naturally collect in the drainage channel 11, which can guide the water to a preset drainage point, keeping the area under the roof dry.

[0062] Based on the above embodiments, as a further preferred option, please refer to... Figure 12 and Figure 13The multiple photovoltaic panels 121 in each column are arranged from front to back. The front and rear frames of the photovoltaic panels 121 are detachably mounted on two adjacent purlins 4, and the rear frame of the photovoltaic panel 121 also overlaps the front frame of another photovoltaic panel 121 adjacent to it. The multiple photovoltaic panels 121 in each row are arranged from right to left, and the left frame of the photovoltaic panel 121 and the right frame of another photovoltaic panel 121 adjacent to it are fastened together.

[0063] It should be noted that the photovoltaic panel 121 is usually surrounded by a frame. The purpose of the frame is to firmly fix the panel and install it in the designated position.

[0064] In this embodiment, the photovoltaic panels 121 can be installed one by one, starting from the lower right corner of the roof, proceeding from right to left and then from bottom to top, forming multiple rows and columns of photovoltaic panels 121. The front and rear frames of the photovoltaic panels 121 can be bolted or clamped onto two adjacent purlins 4, and the rear frame of the photovoltaic panel 121 overlaps with the front frame of another adjacent photovoltaic panel 121. This ensures that rainwater naturally collects in the drainage channel 11 from high to low. More preferably, a sealing strip is provided between the rear frame of the photovoltaic panel 121 and the front frame of the adjacent photovoltaic panel 121 to seal the gap and prevent rainwater backflow. Furthermore, the left frame of the photovoltaic panel 121 and the right frame of the adjacent photovoltaic panel 121 are fastened together, allowing multiple photovoltaic panels 121 to be arranged tightly, further preventing rainwater backflow.

[0065] Based on the above embodiments, as a further preferred option, please refer to... Figure 11 The rear frame of the photovoltaic panel 121 has no sheet material on the side facing it. This prevents the rear frame of the photovoltaic panel 121 from blocking rainwater and prevents dust accumulation on the surface, thereby avoiding reduced power generation efficiency or damage to the photovoltaic panel 121 due to dust accumulation.

[0066] Based on the above embodiments, as a further preferred embodiment, the right side frame of the plurality of photovoltaic panels 121 in the far right column is provided with a first groove, and the plurality of first grooves are connected sequentially from front to back; the left side frame of the plurality of photovoltaic panels 121 in the far left column is provided with a second groove, and the plurality of second grooves are connected sequentially from front to back.

[0067] Thus, the rightmost and leftmost ends of the overall photovoltaic module 12 also have water guide channels 11, which can guide rainwater on the photovoltaic module 12 from high to low and collect in the water guide channels 11 on the lowest purlin 4 below, thereby achieving rapid drainage, eliminating water accumulation and shading, ensuring normal power generation of the photovoltaic panel 121, and avoiding water accumulation and corrosion of the photovoltaic panel 121, thereby improving the service life of the photovoltaic panel 121.

[0068] Based on the above embodiments, as a further preferred embodiment, both the support beam 3 and the purlin 4 are configured as length-adjustable tubes. The length-adjustable tube includes two square tubes, both of which have several equally spaced adjustment holes along their length direction. A fourth fastener is inserted into the adjustment holes of one square tube and the two are aligned.

[0069] In this embodiment, both the support beam 3 and the purlin 4 extend in the left-right direction, both serving to improve the lateral stiffness of the main frame. Both the support beam 3 and the purlin 4 are adjustable-length tubes. After the initial assembly of the carport, if the user needs to increase or decrease the width of the carport, the photovoltaic modules 12 on the roof can be removed, the fourth fastener loosened, the adjustable-length tube stretched or compressed to a suitable length, and then the fourth fastener tightened again, thereby increasing or decreasing the width of the carport. It should be noted that if the carport width is increased, only one or more rows of photovoltaic panels 121 need to be added when reinstalling the photovoltaic modules 12; if the carport width is decreased, only one or more rows of photovoltaic panels 121 need to be removed when reinstalling the photovoltaic modules 12. Thus, the width of the main frame of the carport in this application can be adjusted. If the number of parking spaces or the type of vehicle changes, there is no need to customize a new carport; only adding or removing photovoltaic panels 121 is required, saving costs.

[0070] Preferably, the spacing between the adjustment holes is a multiple of the width of the photovoltaic panel 121, so as to ensure that the photovoltaic panel 121 can be added or removed in the row, avoiding the need to customize a new size of photovoltaic panel 121.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
