Abstract

This invention discloses a prestressed cable-net structure beam, relating to the field of cable-net structure technology. The prestressed cable-net structure beam includes a cable truss mechanism and multiple support components spaced apart along a first direction. The cable truss mechanism includes at least four prestressed cables and multiple transverse stiffening truss structures. The transverse stiffening truss structures improve the stiffness of the prestressed cable-net structure beam, particularly the stiffness of the middle portion of the prestressed cables. Furthermore, the connecting trusses within the same transverse stiffening truss structure enclose a plane, with the area of ​​each plane gradually decreasing from the side closer to the support components to the side farther away. This alters the prestress at different positions of the prestressed cables, further enhancing the stiffness of the prestressed cable-net structure beam. Consequently, the prestressed cable-net structure beam possesses characteristics such as light weight, high vertical and horizontal stiffness, strong spanning capacity, and a certain degree of torsional resistance, making it promising for applications in structural engineering.

Description

Technical Field

[0001] This invention relates to the field of cable net structure technology, and in particular to a prestressed cable net structure beam. Background Technology

[0002] With the development of building structures, the heavy weight and weak span capacity of traditional steel beams and reinforced concrete beams have become increasingly apparent. Cable structures, such as steel strands and wire ropes, have the advantages of light weight, strong load-bearing capacity, and large span capacity, and with proper structural design, they have the potential to replace traditional steel beams and reinforced concrete beams. However, existing cable structures are relatively flexible, resulting in low stiffness, large deformation, and poor torsional resistance. Summary of the Invention

[0003] Therefore, it is necessary to provide a prestressed cable net structure beam to solve the technical problem of insufficient stiffness in existing cable structures.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A prestressed cable net structure beam, comprising:

[0006] Support components, wherein the number of support components is plurality of and they are spaced apart along a first direction; and

[0007] A cable truss mechanism includes at least four prestressed cables and multiple transverse stiffening truss structures. Each prestressed cable connects a support component along a first direction. Each transverse stiffening truss structure is spaced apart along the first direction. Each transverse stiffening truss structure includes a connecting truss and a reinforcing truss. Adjacent prestressed cables are connected by the connecting truss, and spaced-apart prestressed cables are connected by the reinforcing truss. Each connecting truss in the same transverse stiffening truss structure encloses a plane, and the area of ​​each plane gradually decreases from the side closer to the support component to the side farther away from the support component.

[0008] In some embodiments of the prestressed cable net structure beam, the prestressed cable is in the shape of a spatial arc, the horizontal and vertical spacing between adjacent prestressed cables at the ends of the prestressed cables is large, and the horizontal and vertical spacing between adjacent prestressed cables at the mid-span position of the prestressed cables is small.

[0009] In some embodiments of the prestressed cable net structure beam, the connecting truss is perpendicular to the prestressed cable.

[0010] In some embodiments of the prestressed cable net structure beam, the reinforcing truss and the connecting truss are coplanar, such that the transverse stiffening truss is perpendicular to the prestressed cable.

[0011] In some embodiments of the prestressed cable net structure beam, the connecting truss is connected to the prestressed cable via connectors.

[0012] In some embodiments of the prestressed cable net structure beam, the number of prestressed cables is four, including two upper prestressed cables and a lower prestressed cable located directly below the upper prestressed cables. The support assembly includes a column and an upper connecting rod and a lower connecting rod located on the column. The upper connecting rod and the lower connecting rod are parallel to each other. The upper connecting rod is located above the lower connecting rod. The two ends of the upper connecting rod are connected to one end of the two upper prestressed cables, and the two ends of the lower connecting rod are connected to one end of the two lower prestressed cables.

[0013] In some embodiments of the prestressed cable net structure beam, the column counteracts the horizontal force by inclined steel strands or anchor rods, which are anchored to the ground.

[0014] In some embodiments of the prestressed cable net structure beam, the prestressed cable is a steel strand or steel wire rope, the reinforcing truss and the connecting truss are both steel trusses, and the upper prestressed cable and the lower prestressed cable are prestressed and connected to the support assembly.

[0015] Implementing the embodiments of the present invention will have the following beneficial effects:

[0016] The prestressed cable net structure beam described above, in addition to possessing excellent support performance, also exhibits high stiffness. Specifically, the prestressed cable net structure beam includes a cable truss mechanism and multiple support components spaced apart along a first direction. The cable truss mechanism comprises at least four prestressed cables and multiple transverse stiffening truss structures. Each prestressed cable connects the support components along the first direction. Each transverse stiffening truss structure is spaced apart along the first direction and includes connecting trusses and reinforcing trusses. Adjacent prestressed cables are connected by connecting trusses, and spaced-apart prestressed cables are connected by reinforcing trusses. Thus, the use of transverse stiffening trusses enhances the stiffness of the prestressed cable net structure beam, particularly improving the stiffness of the middle portion of the prestressed cables. Furthermore, the connecting trusses located in the same transverse stiffening truss structure form a plane, and the area of ​​each plane gradually decreases from the side closer to the support component to the side farther away from the support component. In this way, by changing the prestress at different positions of the prestressed cable, the stiffness of the prestressed cable net structure beam is further improved, so that the prestressed cable net structure beam has the characteristics of light weight, large vertical and horizontal stiffness, strong spanning capacity and certain torsional resistance, and has broad application prospects in structural engineering.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The prestressed cable net structure beam provided in this embodiment of the invention is a flexible support structure. For example, in this embodiment, the prestressed cable net structure beam can be used to support photovoltaic modules to provide flexible support for the photovoltaic modules; of course, in other embodiments of the invention, the prestressed cable net structure beam can also be used to provide flexible support for other functional components, and this is not the only limitation.

[0024] Please combine them together Figure 1 and Figure 2 The prestressed cable net structure beam provided by the present invention will now be described. This prestressed cable net structure beam includes support components 10 and cable truss mechanisms 20. The number of support components 10 is plurality of and they are spaced apart along a first direction. The cable truss mechanism 20 includes at least four prestressed cables and a plurality of transverse stiffening truss structures 21. Each prestressed cable connects each support component 10 together along the first direction. Each transverse stiffening truss structure 21 is spaced apart along the first direction. Each transverse stiffening truss structure 21 includes connecting trusses 211 and reinforcing trusses 212. Adjacent prestressed cables are connected by connecting trusses 211. Spaced-apart prestressed cables are connected by reinforcing trusses 212. Each connecting truss 211 located in the same transverse stiffening truss structure 21 encloses a plane. The area of ​​each plane gradually decreases from the side closer to the support component 10 to the side farther away from the support component 10.

[0025] In summary, implementing the embodiments of the present invention will have the following beneficial effects: the prestressed cable net structure beam of the above solution, in addition to having excellent support performance, also has high stiffness. Specifically, the prestressed cable net structure beam includes a cable truss mechanism 20 and a plurality of support components 10 spaced apart along a first direction. The cable truss mechanism 20 includes at least four prestressed cables and a plurality of transverse stiffening truss structures 21. Each prestressed cable connects each support component 10 together along the first direction. Each transverse stiffening truss structure 21 is spaced apart along the first direction. The transverse stiffening truss structure 21 includes a connecting truss 211 and a reinforcing truss 212. Adjacent prestressed cables are connected by the connecting truss 211, and spaced-apart prestressed cables are connected by the reinforcing truss 212. Thus, the arrangement of the transverse stiffening truss structures 21 can improve the stiffness of the prestressed cable net structure beam, especially the stiffness of the middle part of the prestressed cable. Furthermore, the connecting trusses 211 located in the same transverse stiffening truss structure 21 form a plane, and the area of ​​each plane gradually decreases from the side closer to the support component 10 to the side farther away from the support component 10. In this way, by changing the prestress at different positions of the prestressed cable, the stiffness of the prestressed cable net structure beam is further improved, so that the prestressed cable net structure beam has the characteristics of light weight, large vertical and horizontal stiffness, strong spanning capacity and certain torsional resistance, and has broad application prospects in structural engineering.

[0026] In one embodiment, the prestressed cable is spatially curved, with larger horizontal and vertical spacing between adjacent prestressed cables at the ends and smaller horizontal and vertical spacing between adjacent prestressed cables at the mid-span.

[0027] In one embodiment, such as Figure 2 As shown, the connecting truss 211 is perpendicular to the prestressing cable. This perpendicularity of the connecting truss 211 to the prestressing cable improves the connection strength between adjacent prestressing cables, enhances the torsional resistance between prestressing cables, and thus improves the prestressing cables' ability to resist lateral winds, preventing significant vibration and overturning of the prestressed cable net structure beam. The positional relationship between the connecting truss 211 and the prestressing cable includes, but is not limited to, the following: the connecting trusses 211 can all be located outside the prestressing cable and connected to it, with each prestressing cable located within the space enclosed by each connecting truss 211. Alternatively, the connecting trusses 211 can all be located inside the prestressing cable and connected to it, with each prestressing cable located outside the space enclosed by each connecting truss 211. Alternatively, each connecting truss 211 can have its two ends connected to adjacent prestressing cables respectively. It can be understood that in other embodiments, the above-mentioned positional relationship between the connecting trusses 211 and the prestressing cable can be symmetrically arranged in the cable truss mechanism 20.

[0028] In some embodiments, the plane of the connecting truss 211 and the plane of the reinforcing truss 212 may not be coplanar, each used to improve the stiffness of the prestressed cable. Specifically, the reinforcing truss 212 is arranged perpendicular to the prestressed cable. All reinforcing trusses 212 located in the same transverse stiffening truss structure 21 are coplanar. That is, the plane of the connecting truss 211 and the plane of the reinforcing truss 212 are parallel to each other. The plane of the reinforcing truss 212 is located between adjacent planes. Further, the plane of the reinforcing truss 212 is located on the plane of symmetry of adjacent planes. This ensures that the stress on the prestressed cable is relatively uniform throughout, thereby improving the stability of the prestressed cable net structure beam. Further, the reinforcing trusses 212 may be overlapped, allowing relative sliding during use for fine adjustments to avoid local stress concentration caused by processing errors, which could lead to instability in the transverse stiffening truss structure 21. It can be understood that in other embodiments, the reinforcing trusses 212 are fixedly connected, meaning the middle parts of two reinforcing trusses 212 are connected as one unit. This improves the stability of the transverse stiffening truss structure 21, allowing each prestressed cable to achieve the preset shape.

[0029] In this embodiment, as Figure 2 As shown, the reinforcing truss 212 and the connecting truss 211 are coplanar, so that the transverse stiffening truss 21 is perpendicular to the prestressing cable. This ensures that the corresponding reinforcing truss 212 and connecting truss 211 act on the same position of the prestressing cable, avoiding bending and fracture weak points in the prestressing cable caused by different points of application. Simultaneously, the coplanarity of the reinforcing truss 212 and the connecting truss 211 also ensures that the forces generated by each reinforcing truss 212 and each connecting truss 211 are coplanar, further improving the stability of the cable-stayed girder mechanism 20. Furthermore, as mentioned above, the connecting truss 211 is perpendicular to the prestressing cable, indicating that the transverse stiffening truss structure 21 as a whole is perpendicular to the prestressing cable, thereby further improving the stress stability of the prestressing cable.

[0030] In one embodiment, please refer to... Figure 2 The transverse stiffening truss structures 21 are evenly spaced along the extension direction of the prestressed cables. This ensures relatively uniform stress distribution throughout the prestressed cables, preventing instability in the transverse stiffening truss structures 21 caused by excessive stress, and thus preventing damage to the connection structure of the transverse stiffening truss structures 21, which could lead to failure of the prestressed cable net structure beam. Furthermore, the areas of the planes between adjacent support components 10 are symmetrical to further improve the stability of the cable truss mechanism 20. It can be understood that in other embodiments, the transverse stiffening truss structures 21 may also be unequally spaced along the extension direction of the prestressed cables.

[0031] In one embodiment, the connecting truss 211 is connected to the prestressed cable via a connector. It can be understood that in other embodiments, the reinforcing truss 212 can also be connected to the prestressed cable via a connector. This connection via connectors facilitates the connection of the connecting truss 211 and the reinforcing truss 212 to the prestressed cable. In this embodiment, the connector can be integrally connected to the connecting truss 211 or the reinforcing truss 212, and the installation position of the connector on the prestressed cable can be pre-set to ensure that the transverse stiffening truss structure 21 is evenly spaced on the prestressed cable. It can be understood that in other embodiments, the connector can be detachably connected to the prestressed cable, facilitating adjustment of the connector's position, thereby adjusting the position of the transverse stiffening truss structure 21, and ultimately finding an optimal connection position for the transverse stiffening truss structure 21. Furthermore, the connector can be a ring-shaped structure, including a fixed part and a rotating part. The fixed part is used to connect with the connecting truss 211 or the reinforcing truss 212. One end of the rotating part is rotatably connected to the fixed part. The fixed part and the rotating part enclose a ring-shaped clamping space. The prestressed cable can pass through the clamping space to be clamped onto the fixed part by the rotating part. The other end of the rotating part can be connected to the fixed part by bolts or clips. It can be understood that in other embodiments, the connector can also be a hook-shaped structure with a fastening gap.

[0032] The prestressed cable has a corresponding interlocking groove to reduce its radial dimension, allowing it to enter the hook structure through the interlocking gap. Alternatively, the prestressed cable at the interlocking groove can complement the interlocking gap. This restriction prevents movement of the connector relative to the prestressed cable, thus improving the stability of the connection between the connecting truss 211 and the reinforcing truss 212 and the prestressed cable. Simultaneously, the complementarity of the interlocking groove also reduces the impact on the stiffness of the prestressed cable caused by the groove. After complementing the interlocking gap, the connector and prestressed cable can be integrated by welding, bonding, or connecting structures. Therefore, the interlocking groove also serves a positioning function, facilitating the assembly of the connecting truss 211 and the reinforcing truss 212 with the prestressed cable, improving assembly efficiency, and reducing labor costs.

[0033] In one embodiment, one end of an adjacent connecting truss 211 and one end of a corresponding reinforcing truss 212 are connected by the same connector. This shared connector ensures the stability of the prestressed cable under stress, meaning the forces are directed in the same plane, preventing torsion of the prestressed cable, and reducing the number of connectors used, thus lowering costs. Similarly, the connector can also be a ring-shaped structure, including a fixed part and a rotating part. The fixed part forms a 45° angle with both the connecting truss 211 and the reinforcing truss 212. One end of the rotating part is rotatably connected to the fixed part, and the fixed and rotating parts enclose a ring-shaped clamping space. The prestressed cable can pass through this clamping space and be clamped onto the fixed part by the rotating part. The other end of the rotating part can be connected to the fixed part by bolts or clips. Likewise, the connector can also be a hook-shaped structure with a snap-fit ​​gap. The hook-shaped structure connects both the connecting truss 211 and the reinforcing truss 212, creating a 45° angle between adjacent connecting trusses 211 and reinforcing trusses 212. The prestressed cables have corresponding interlocking grooves to reduce their radial dimensions, allowing the interlocking gaps in the prestressed cables to enter the hook-shaped structure. Alternatively, the interlocking grooves can complement the interlocking gaps, thus preventing movement of the connectors relative to the prestressed cables due to the constraint of the interlocking grooves, thereby improving the stability of the connection between the connecting trusses 211 and the reinforcing trusses 212 and the prestressed cables. Simultaneously, the complementary nature of the interlocking grooves on the prestressed cables also reduces the impact of the interlocking grooves on the stiffness of the prestressed cables. After the prestressed cable at the interlocking slot is complementary to the interlocking gap, the connector and the prestressed cable can be connected together by welding, bonding or connecting structure. Therefore, the interlocking slot can also improve the positioning function, so as to facilitate the assembly of the connecting truss 211 and the reinforcing truss 212 with the prestressed cable and the prestressed cable, improve the assembly efficiency, and thus reduce labor costs.

[0034] In one embodiment, please combine Figures 1 to 3 The number of prestressing cables is four, including two upper prestressing cables 22 and a lower prestressing cable 23 located directly below the upper prestressing cables 22. The two upper prestressing cables 22 and the two lower prestressing cables 23 are arranged in a rectangular pattern. The transverse stiffening truss structure 21 maintains the aforementioned distribution of the two upper prestressing cables 22 and the two lower prestressing cables 23. Figure 3The support assembly 10 includes a column 11 and an upper connecting rod 12 and a lower connecting rod 13 located on the column 11. The upper connecting rod 12 and the lower connecting rod 13 are parallel to each other. The upper connecting rod 12 is located above the lower connecting rod 13, and both ends of the upper connecting rod 12 are connected to one end of two upper prestressed cables 22, and both ends of the lower connecting rod 13 are connected to one end of two lower prestressed cables 23. In this embodiment, there are three support assemblies 10, which are arranged sequentially along the first direction. The two ends of the prestressed cables are connected to the support assemblies 10 located on both sides, and the support assembly 10 located in the middle can further improve the stability of the prestressed cables. It can be understood that in other embodiments, the number of support assemblies 10 can also be two, four or more, and each support assembly 10 is arranged sequentially along the first direction. In addition, in other embodiments, there are multiple support assemblies 10, and each support assembly 10 can also be distributed in a matrix, that is, including support assemblies 10 spaced apart along the first direction and also including support assemblies 10 spaced apart along the second direction, wherein the first direction is perpendicular to the second direction.

[0035] In another embodiment, the number of prestressing cables may be five or more, and the prestressing cables are distributed in a polygonal pattern. Adjacent prestressing cables are connected by connecting trusses 211. Prestressing cables arranged at intervals are connected by reinforcing trusses 212.

[0036] In one embodiment, such as Figure 1 As shown, the column 11 counteracts the horizontal force through diagonally stretched steel strands or anchor rods 231, which are anchored to the ground. In this embodiment, the diagonally stretched steel strands or anchor rods 231 are connected to the fixed column 30.

[0037] In one embodiment, the upper connecting rod 12 includes two first branches 121, each in the shape of a right trapezoid. The larger end of each first branch 121 is connected to the column 11, and the right-angled side of each first branch 121 is perpendicular to the column 11. First connecting portions 122 are provided at both ends of the upper connecting rod 12, located on the right-angled side of each first branch 121, and are used to connect to the upper prestressed cable 22. The lower connecting rod 13 includes two second branches 131, each in the shape of a right trapezoid. The larger end of each second branch 131 is connected to the column 11, and the right-angled side of each second branch 131 is perpendicular to the column 11. Second connecting portions 132 are provided at both ends of the lower connecting rod 13, located on the right-angled side of each second branch 131, and are used to connect to the lower prestressed cable 23. The right-angled sides of the first branches 121 and the second branches 131 are positioned opposite to each other. During use, the connection between the upper prestressed cable 22 and the first connecting part 122 provides a downward pressure to the first branch 121. The first connecting part 122 is located on the right-angle waist of the first branch 121, and the right-angle waist of the first branch 121 is opposite to the right-angle waist of the second branch 131. This allows the downward pressure to act on the first branch 121 through the first connecting part 122, causing the first branch 121 to bend downward. At this time, since the inclined waist of the first branch 121 is inclined upward from the column 11, the inclined waist of the first branch 121 tends to be compressed when subjected to downward pressure. This tendency can prevent the first branch 121 from continuing to bend downward, thereby improving the stability of the support component 10 structure and preventing the position of the upper prestressed cable 22 from changing, which would affect the overall stability of the cable truss mechanism 20. Similarly, during use, the connection between the lower prestressed cable 23 and the second connecting part 132 provides a downward force to the second branch 131. The second connecting part 132 is located on the right-angled waist of the second branch 131, and the right-angled waist of the first branch 121 is opposite to the right-angled waist of the second branch 131, so that the aforementioned downward force is actually a downward tension. This tension acts on the second branch 131 through the second connecting part 132, causing the second branch 131 to bend downward. At this time, since the inclined waist of the second branch 131 is inclined downward from the column 11, the inclined waist of the second branch 131 tends to be stretched when subjected to the downward tension. This tendency can prevent the second branch 131 from bending further downward, thereby improving the stability of the support assembly 10 structure and preventing the position of the lower prestressed cable 23 from changing, thus affecting the overall stability of the cable girder mechanism 20. Thus, the above arrangement can further improve the overall stability of the support assembly 10.

[0038] In this embodiment, the prestressed cable is a steel strand or wire rope, and both the reinforcing truss 212 and the connecting truss 211 are steel trusses. The upper prestressed cable 22 and the lower prestressed cable 23 are prestressed and connected to the support assembly 10. There are three support assemblies 10, which are arranged sequentially along the first direction. Nine transverse stiffening truss structures 21 are provided between adjacent support assemblies 10. The nine transverse stiffening truss structures 21 and the corresponding two adjacent support assemblies 10 are arranged at equal intervals. Each connecting truss 211 in the same transverse stiffening truss structure 21 forms a plane, and the area of ​​each plane decreases from the side closer to the support assembly 10 to the side farther away from the support assembly 10. That is, the area of ​​each plane gradually increases from the symmetrical face of the adjacent support assembly 10 to the side of the support assembly 10, and the ratio of the areas of adjacent planes is 1.21 to 1.44.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
