Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic technology, and particularly relates to a photovoltaic support.

Background Art

[0002] At present, in the portal photovoltaic support, the truss scheme accounts for the largest proportion. For example, the Chinese utility model patent with the publication number CN222140287U discloses an assembled truss, which includes a truss beam and a plurality of truss columns. The plurality of truss columns are evenly arranged and fixedly installed on the lower side of the truss beam through bolts; the truss beam includes an upper chord, a lower chord and a plurality of web members. The plurality of web members are evenly arranged and fixedly installed between the upper chord and the lower chord through bolts. The cross-section of the upper chord is in a "channel" - shaped structure, and the opening of the "channel" - shaped structure of the upper chord faces upward and is used as a water trough; the truss column includes an inner chord, an outer chord and a plurality of column web members. The plurality of column web members are evenly arranged and fixedly installed between the inner chord and the outer chord through bolts.

[0003] However, in the existing truss scheme, while ensuring that the front and rear columns can span a large distance and cross over a house, trusses need to be welded under the components to ensure strength. There are too many welding points, which increases the construction duration. Moreover, the truss structures of different schemes are different, and it is easy to make mistakes during construction. Therefore, the truss scheme has the disadvantages of cumbersome construction, long construction time and complexity.

Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic portal steel support, which is convenient for construction and improves construction efficiency.

[0005] To solve the above technical problem, the utility model adopts the following technical scheme:

[0006] A photovoltaic portal steel support includes two side steel frame columns arranged side by side, a foundation connected to the bottom ends of the steel frame columns, two steel frame beams connecting the two side steel frame columns, and purlins perpendicularly and cross - fixed above the steel frame beams. Column connection steel plates are provided inside the tops of the steel frame columns. The steel frame beams are obliquely arranged. Beam connection steel plates are provided at both ends of the steel frame beams. The beam connection steel plates at the obliquely lower ends of the steel frame beams are butted against the column connection steel plates and fixed by bolts. The beam connection steel plates at the obliquely upper ends of the two steel frame beams are butted against each other and fixed by bolts.

[0007] Preferably, the photovoltaic portal steel support further includes purlin support plates. The purlins are connected to the purlin support plates by bolts, and the bottoms of the purlin support plates are welded to the steel frame beams.

[0008] Preferably, stiffening ribs are welded between the purlin support plates and the steel frame beams.

[0009] Preferably, the steel frame beams are variable - section steel.

[0010] Preferably, the steel frame beam is composed of at least two branch segments joined together.

[0011] Preferably, the connecting ends of two adjacent branch sections of the steel frame beam are provided with connecting steel plates, and the connecting steel plates of the two branch sections are connected and fixed by bolts.

[0012] Preferably, the steel frame column is a variable cross-section steel, and the cross-sectional area gradually increases from bottom to top.

[0013] Preferably, a column base plate is welded to the bottom end of the steel frame column.

[0014] Preferably, the foundation is a concrete structure, and anchor bolts are pre-embedded in the foundation. The anchor bolts pass through the column base plate and are fixed by connecting nuts.

[0015] Preferably, the steel frame beams and steel frame columns are made of I-beams or H-beams.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. The main structure of the portal steel support consists of steel frame beams and steel frame columns. The steel frame beams and columns can be made directly from structural steel, which is not only lightweight and easy to construct, but also allows for the selection of larger cross-sectional dimensions as needed, ensuring structural stability and reliability.

[0018] During on-site construction, the connection nodes of the portal steel support include the connection nodes between the steel frame beams and steel frame columns, the connection nodes between two steel frame beams, and the connection nodes between the steel frame columns and the foundation. There are only four connection nodes in total. The fewer connection nodes and the simpler structure, and all of these connection nodes are bolted, which can improve the accuracy and efficiency of construction.

[0019] 2. The purlins and purlin brackets are connected by bolts. The purlin brackets can be used to position the purlins and ensure that the purlins are securely fixed. The bolt connection can improve the accuracy and efficiency of construction.

[0020] 3. Stiffening ribs are welded between the purlin support plate and the steel frame beam to increase the connection strength and the stability of the purlin.

[0021] 4. Steel frame beams and columns can be made of variable cross-section steel. The cross-sectional dimensions are increased in areas requiring greater loads and decreased in areas with lower stress. This variation in cross-sectional dimensions allows for a more rational distribution of internal forces when the beam is under load, thereby optimizing the structure and saving materials.

[0022] 5. The bottom of the steel frame column is welded with a column base plate. The foundation is a concrete structure with anchor bolts pre-embedded in it. The anchor bolts pass through the column base plate and are fixed with nuts. The concrete foundation is stable and reliable. The steel frame column is fixed to the anchor bolts through the column base plate, which facilitates rapid construction.

[0023] 6. The steel frame beams and columns are made of I-beams or H-beams, which saves materials and reduces costs.

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] like Figures 1 to 4 As shown, this embodiment provides a photovoltaic portal steel support structure, including two steel frame columns 1 arranged side by side, a foundation 2 connected to the bottom of the steel frame columns, two steel frame beams 3 connecting the two steel frame columns, and purlins 5 vertically and intersectingly fixed above the steel frame beams 3. Here, the direction in which the two steel frame columns 1 are arranged side by side can be defined as longitudinal, and the extension direction of the purlins 5 as transverse. The two steel frame columns 1 are arranged in pairs on both sides longitudinally, with two steel frame beams 3 between each pair. The specific number of beams 3 arranged transversely is determined according to the different arrangement of the photovoltaic modules. The number of purlins 5 is also determined as needed, and the photovoltaic modules 6 are fixed to the purlins.

[0037] In this embodiment, the main structure of the portal steel support consists of steel frame beams and steel frame columns. The steel frame beams and columns can be made directly from structural steel, which is not only lightweight and easy to construct, but also allows for the selection of larger cross-sectional dimensions to ensure structural stability and reliability. Specifically, the top inner side of the steel frame column 1 is provided with a column connecting steel plate 12, and the steel frame beam 3 is inclined, with beam connecting steel plates 34 at both ends. Stiffening plates can be installed between the column connecting steel plate 12 and the main body of the steel frame column, and between the beam connecting steel plate 34 and the main body of the steel frame beam, to improve connection strength. Specifically, the beam connecting steel plate 34 at the downward inclined end of the steel frame beam 3 is connected to the column connecting steel plate 12 and fixed with bolts, and the beam connecting steel plates 34 at the upward inclined ends of two steel frame beams are connected and fixed with bolts. All these beam-column connection nodes are bolted, which improves construction accuracy and efficiency.

[0038] In some embodiments, the photovoltaic portal steel support also includes a purlin support plate 4, which is also made of steel and is perpendicular to the steel frame beam 3. The purlins 5 are bolted to the purlin support plate 4. The bottom of the purlin support plate 4 can be bolted or welded to the steel frame beam 3. The purlin support plate helps to position the purlins and ensures reliable fixing. Additionally, stiffening ribs 41 can be welded between the purlin support plate 4 and the steel frame beam 3 to increase connection strength and purlin stability.

[0039] In some embodiments, the steel frame beam 3 is a variable cross-section steel section. The steel frame beam 3 may be composed of at least two branch sections joined together, for example, two branch sections, namely a first branch section 31 and a second branch section 32. The first branch section 31 is connected to the steel frame column 1, and the cross-sectional area of ​​both branch sections gradually increases from the joint end to the other end. The joint ends of the two branch sections of the steel frame beam are provided with joint steel plates 33, and the joint steel plates 33 of the two branch sections are joined together and fixed with bolts.

[0040] In some embodiments, the steel frame column 1 is a variable cross-section steel, and the cross-sectional area gradually increases from bottom to top.

[0041] like Figure 3 As shown, a column base plate 11 is welded to the bottom end of the steel frame column 1. The foundation 2 is a concrete structure, in which anchor bolts 21 are pre-embedded. The anchor bolts 21 pass through the column base plate 11 and are fixed with nuts. The concrete foundation is relatively stable. Connecting the column base plate to the foundation with anchor bolts and nuts facilitates construction and improves construction efficiency.

[0042] Preferably, the steel frame beam 3 and steel frame column 1 are made of I-beams or H-beams. They can be variable cross-section solid-web welded I-beams or variable cross-section solid-web welded H-beams. The cross-sectional dimensions are increased in areas requiring greater load bearing and decreased in areas with less stress. This variation in cross-sectional dimensions allows the beam to distribute internal forces more rationally when bearing loads, thereby optimizing the structure and saving materials. Of course, they can also be uniform cross-section solid-web welded I-beams or uniform cross-section solid-web welded H-beams.

[0043] Therefore, it can be seen that the present invention is convenient and easy to construct, has a high accuracy rate, and can improve construction quality and efficiency.

Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above.
