Description

TECHNICAL FIELD

[0001] The present application relates to the field of building technology, in particular to a support structure, which can be used for building roof. BACKGROUND

[0002] In recent years, with the continuous development and application of modern buildings, more and more buildings, especially public buildings, have higher requirements for their support columns.

[0003] The tree structure is a kind of spatial bionic structure, which belongs to the category of building bionic structure. It is a novel structure form with reasonable force transmission path, high bearing capacity and wide support coverage, and can form a larger support space with smaller rods.

[0004] The single-layer grid structure system supported by the tree structure is favored in spatial structure design in recent years due to its simple and beautiful architectural style, strong adaptability to free-form surfaces, etc. The single-layer grid structure has fewer rods, and the structure is often exposed in engineering application, which has rich architectural expression and highlights the building and structure. However, things have two sides, and the single-layer grid structure also has the problems of poor structural stiffness and stability due to the small number of rods and small structure rise ratio.

[0005] For example, the patent file (publication number CN217870962U) of China is a whole variable cross-section branch column expansion support structure, which includes a column and a branch cantilever beam. The branch cantilever beam is uniformly fixed on the outer surface of the column in the circumferential direction. The branch cantilever beam is divided into a support section one and a support section two, the support section one is arranged between the column and the support section two, and the support section two is used for supporting the steel structure. The cross-sectional area of the support section one gradually increases along the direction from the support section two to the column. This support structure changes the cross-section of the branch cantilever beam, increases the cross-sectional moment of inertia, and improves the bending bearing capacity.

[0006] However, the column and the branch cantilever beam of this support structure are directly welded. When the load received by the branch cantilever beam is transmitted to the column, the horizontal forces of the multiple branch cantilever beams cancel each other out, and the connection between the column and the branch cantilever beam is subjected to a large shear stress. The excessive shear stress is likely to separate the column and the branch cantilever beam from the connection. SUMMARY

[0007] The purpose of the present application is to solve the technical problem that the column and the branch cantilever beam of the support structure in the prior art are directly welded, when the load received by the branch cantilever beam is transmitted to the column, the connection between the column and the branch cantilever beam is subjected to a large shear stress, and the excessive shear stress is likely to separate the column and the branch cantilever beam from the connection.

[0008] To solve the above-mentioned technical problems, the present invention discloses a support structure, which includes a connecting rod, a main support rod, and a plurality of secondary support rods. One end of each of the secondary support rods is connected to one end of the main support rod via a first connecting node, and the secondary support rods extend divergently from their respective ends and are connected to the connecting rod via a second connecting node.

[0009] The first connecting node is provided with a hollow first connecting body, which has a main connecting part and a secondary connecting part arranged opposite to each other. One end of the main supporting rod is connected to the main connecting part, and one end of each of the multiple secondary supporting rods is connected to the secondary connecting part.

[0010] Furthermore, the first connector has a first auxiliary reinforcing component on the outer periphery of the main connecting part and a first inner reinforcing component inside the first connector.

[0011] Using the above technical solution, this support structure supports the connecting rod through a main support rod and multiple secondary support rods. The connecting rod can support the roof covering components of the building or be directly exposed to the outside. The main support rod, as the main supporting component, has its end facing away from the connecting rod fixedly connected to the supporting platform (e.g., the ground). Multiple secondary support rods are arranged between the main support rod and the connecting rod. One end of each secondary support rod is connected to one end of the main support rod via a first connecting node and extends in a divergent manner, forming a tree-like structure. Specifically, the main support rod is similar to the trunk in a tree branch structure, and the secondary support rods are similar to the branches in a tree-like structure. The connecting rod is connected to the secondary support rods via a second connecting node. The load on the connecting rod is applied to the secondary support rods through the second connecting node, and the secondary support rods then transfer the load to the main support rod through the first connecting node. This dispersed arrangement not only allows the loads of the multiple secondary support rods to partially cancel each other out at the first connecting node, dispersing external forces and reducing the impact force on individual secondary support rods, but also ensures that the main support rod is subjected to uniform force in the circumferential direction, improving the stability of the support structure.

[0012] The first connecting node features a hollow first connecting body. This first connecting body is connected to the main supporting rod via a main connecting part and to multiple secondary supporting rods via a secondary connecting part. Compared to the direct welding method in the prior art, the first connecting body greatly improves the connection strength and stability between the main supporting rod and the multiple secondary supporting rods. Furthermore, the hollow first connecting body can achieve the requirement of lightweighting while ensuring connection strength, thus reducing the load on the main supporting rod.

[0013] Furthermore, the first auxiliary reinforcing component located on the outer periphery of the main connecting part can enhance the connection strength between the main connecting part and the supporting main rod, preventing connection failure due to excessive force; while the first inner reinforcing component located inside the first connecting body can enhance the structural strength of the first connecting body and reduce the risk of plastic deformation of the first connecting body.

[0014] Optionally, in one embodiment, the first connector is configured as a connecting ball, the main connector is configured as the hemisphere of the connecting ball near the supporting main rod, and the secondary connector is configured as the hemisphere of the connecting ball near the multiple supporting secondary rods.

[0015] Furthermore, the extended axis of the main support rod passes through the center of the connecting ball, and the extended axes of multiple secondary support rods converge at a point on the extended axis of the main support rod.

[0016] By adopting the above technical solution, the design of the connecting ball ensures that the first connecting body has the same curvature and strength in all directions, thereby ensuring the uniformity of the connection with the main supporting rod and multiple secondary supporting rods, reducing the risk of structural damage caused by load concentration, improving the overall durability of the structure, and enabling each secondary supporting rod to evenly distribute the load, further improving the stability of the structure.

[0017] Furthermore, the extension line of the axis of the main support rod passes through the center of the connecting ball, enabling the main connecting part, which is set as a hemispherical surface, to be stably connected to the main support rod, further improving the connection stability between the first connecting body and the main support rod. The extension lines of the axes of multiple secondary support rods intersect at a point on the extension line of the axis of the main support rod. This design allows all secondary support rods to form a common intersection point on the connecting ball, thereby realizing the concentrated transmission and dispersion of force.

[0018] Optionally, in one embodiment, a first reinforcing plate is provided on the outer periphery of the connecting ball near the supporting main rod, the first reinforcing plate extending in a circumferential direction parallel to the supporting main rod, and a second reinforcing plate is provided on the outer periphery of the supporting main rod near the connecting ball, the second reinforcing plate extending in a circumferential direction along the supporting main rod.

[0019] Furthermore, the first auxiliary reinforcing component is disposed between the first reinforcing plate and the second reinforcing plate, and includes a plurality of reinforcing ribs spaced circumferentially along the main support rod. One end of each of the plurality of reinforcing ribs is connected to the first reinforcing plate, and the other end is connected to the second reinforcing plate.

[0020] Using the above technical solution, the first reinforcing plate is set on the outer periphery of the connecting ball near the supporting main rod, which increases the strength and rigidity of the connection area between the connecting ball and the supporting main rod; the second reinforcing plate is set on the outer periphery of the supporting main rod near the connecting ball, which enhances the load-bearing capacity of the supporting main rod in this area.

[0021] The first auxiliary reinforcing component is configured as multiple reinforcing ribs, which are spaced apart circumferentially along the main support rod. One end of each reinforcing rib is connected to the first reinforcing plate and the other end is connected to the second reinforcing plate, thereby forming a bridge-like connection between the first and second reinforcing plates. This not only enhances the connection between the reinforcing plates but also improves the stability of the overall structure by distributing the load.

[0022] Therefore, this design further enhances the stability and connection strength of the support structure, optimizes the load distribution, and improves the overall durability of the structure by setting reinforcing plates on the outer periphery of the connecting ball and the supporting main rod, and setting multiple reinforcing ribs between them as the first auxiliary reinforcing components.

[0023] Optionally, in one embodiment, the first inner reinforcement component includes a plurality of first inner reinforcement plates disposed within the connecting ball.

[0024] In this configuration, each of the multiple first inner reinforcing plates passes through the center of the connecting ball, and the outer edge of the first inner reinforcing plate is in contact with the inner surface of the connecting ball.

[0025] By employing the above technical solution and incorporating a reinforcing plate inside the connecting sphere, the load-bearing capacity of the connecting sphere can be significantly improved, enabling it to withstand greater loads without failure. Furthermore, the reinforcing plate design enhances the structural stability of the connecting sphere, ensuring the overall structure maintains good performance even under complex working conditions.

[0026] In addition, since the reinforcing plate passes through the center of the ball, it can effectively and evenly transfer the load from the secondary support rod to the main support rod, reducing the risk of structural deformation or damage caused by uneven load distribution.

[0027] In order to improve the connection strength between the supporting secondary rod and the connecting rod, in one embodiment, the second connecting node is provided with a hollow second connecting body, and a second inner reinforcing component is provided inside the second connecting body.

[0028] The second connecting body is set as a connecting cylinder, the axis of the connecting cylinder is perpendicular to the axis of the connecting rod, and the connecting rod and multiple supporting secondary rods are connected to the side wall of the corresponding connecting cylinder.

[0029] Furthermore, both ends of the connecting cylinder are provided with sealing plates, and the second inner reinforcing assembly includes multiple second inner reinforcing plates disposed inside the connecting cylinder. The multiple second inner reinforcing plates are spaced apart along the axial direction of the connecting cylinder, and the outer edge of each second inner reinforcing plate is in contact with the inner surface of the side wall of the connecting cylinder.

[0030] By adopting the above technical solution, and by designing a hollow second connecting body (i.e., a connecting cylinder) and setting a second internal reinforcing component inside it, the connection strength between the supporting secondary rod and the connecting rod can be significantly improved, thereby further enhancing the stability and durability of the entire support structure.

[0031] The axis of the connecting cylinder is perpendicular to the axis of the connecting rod. This design allows the connecting cylinder to effectively connect the secondary support rod and the connecting rod, forming a stable connection structure.

[0032] Specifically, both ends of the connecting cylinder are equipped with sealing plates, which not only prevents foreign objects from entering the connecting cylinder, but also increases the rigidity and strength of the connecting cylinder, further improving the stability of the connection node; multiple second inner reinforcing plates are arranged at intervals along the axis of the connecting cylinder. This design allows the second inner reinforcing plates to evenly distribute the stress inside the connecting cylinder, preventing structural damage caused by excessive local stress.

[0033] An embodiment of the present invention also discloses a building roof, comprising a plurality of the above-described support structures, wherein the connecting rods of the plurality of support structures are parallel and staggered or intersect each other.

[0034] Among them, two adjacent and intersecting support structures are connected by a second connecting node, with one connecting rod intersecting the other connecting rod.

[0035] Furthermore, the building roof also includes multiple connecting secondary rods, which intersect with the connecting rod and connect to the connecting rod at a position offset from the second connecting node.

[0036] Furthermore, a reinforcing ring plate is fitted at the intersection of the connecting rod and the secondary connecting rod, and the reinforcing ring plate is attached to the corresponding outer surface of the secondary connecting rod.

[0037] Using the above technical solution, the building roof consists of multiple supporting structures. The connecting rods of these supporting structures are parallel and staggered or intersect each other, forming a complex supporting network. Adjacent and intersecting supporting structures are connected by a second connecting node, which enhances the connection strength between the supporting structures and improves the stability of the overall structure.

[0038] Furthermore, the presence of the connecting secondary rod allows the building roof to better distribute loads when subjected to external forces, reducing the risk of structural damage due to excessive local stress. A reinforcing ring plate is fitted at the intersection of the connecting rod and the connecting secondary rod, enhancing the connection strength between them.

[0039] Therefore, this building roof adopts multiple of the above-mentioned support structures and cleverly arranges connecting rods and secondary connecting rods to achieve efficient support and stable connection of the structure, which can meet various scenarios that need to withstand high loads and complex working conditions.

[0058] In existing technologies, the support structure's columns and branch beams are directly welded together. When the load received by the branch beams is transferred to the columns, the horizontal forces of multiple branch beams cancel each other out, while the connection between the columns and branch beams is subjected to extremely high shear stress. Excessive shear stress is very likely to separate the columns and branch beams from the connection.

[0059] To this end, the present invention proposes a support structure, which includes a connecting rod, a main support rod, and multiple secondary support rods. One end of each of the multiple secondary support rods is connected to one end of the main support rod via a first connecting node, and the multiple secondary support rods extend divergently from their respective ends and are connected to the connecting rod via a second connecting node.

[0060] It should be noted that multiple secondary support members and the main support members form a tree-like structure. The tree-like support structure disperses and transfers loads through multiple paths, which can significantly reduce the bending moment and shear force borne by a single support member, thereby improving the load-bearing capacity and stability of the entire structure.

[0061] Furthermore, this structural form can make more efficient use of materials. Through reasonable branch design, it can save material usage and reduce structural weight while ensuring structural strength, thus facilitating cost control of the entire structural system.

[0062] In addition, the unique branching shape of the tree-like support structure can reduce the longitudinal span of the structure, especially without adding more intermediate supports, and can achieve a larger column-free space.

[0063] Furthermore, in order to improve the connection strength between the multiple secondary support rods and the main support rod, the support structure provided by the present invention provides a hollow first connector at the first connection node. The first connector not only serves to connect the secondary support rods and the main support rod, but also enhances the stability of the connection through its internal structure.

[0064] Furthermore, in order to improve the structural strength of the first connector, a first auxiliary reinforcing component is provided on the outer periphery of the main connecting part, and a first inner reinforcing component is provided inside the first connector.

[0065] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0066] like Figure 1As shown, an embodiment of the present invention provides a support structure 10, which includes a connecting rod 100, a main support rod 200, and a plurality of secondary support rods 300. The connecting rod 100 can support the covering component of the building roof or be directly exposed to the outside. The main support rod 200 serves as the main support component, with one end of it facing away from the connecting rod 100 fixedly connected to a support platform (e.g., the ground). The plurality of secondary support rods 300 are disposed between the main support rod 200 and the connecting rod 100. One end of the plurality of secondary support rods 300 is connected to one end of the main support rod 200 by a first connecting node 400 and extends in a divergent manner, so that the main support rod 200 and the plurality of secondary support rods 300 form a tree-like structure. Specifically, the main support rod 200 is similar to the trunk in a tree branch structure, and the multiple secondary support rods 300 are similar to the branches in a tree structure. The connecting rod 100 is connected to the multiple secondary support rods 300 through the second connecting node 500. The load on the connecting rod 100 is applied to the secondary support rods 300 through the second connecting node 500, and the secondary support rods 300 transmit the load to the main support rod 200 through the first connecting node 400. The distributed arrangement not only makes the loads of the multiple secondary support rods 300 partially cancel each other out at the first connecting node 400, disperses the external force, and reduces the impact force on the individual secondary support rods 300, but also makes the main support rod 200 uniformly stressed in the circumferential direction, thus improving the stability of the support structure 10.

[0067] The first connecting node 400 is provided with a hollow first connecting body 410. The first connecting body 410 is connected to the main supporting rod 200 through the main connecting part 411 and connected to multiple secondary supporting rods 300 through the secondary connecting part 412. Compared with the direct welding method in the prior art, the first connecting body 410 greatly improves the connection strength and stability between the main supporting rod 200 and the multiple secondary supporting rods 300. In addition, the hollow first connecting body 410 can achieve the requirement of lightweighting while ensuring connection strength and reducing the load on the main supporting rod 200.

[0068] Furthermore, a first auxiliary reinforcing component 413 is provided on the outer periphery of the main connecting part 411, which can enhance the connection strength between the main connecting part 411 and the supporting main rod 200 and prevent connection failure due to excessive force; a first inner reinforcing component 414 is provided inside the first connecting body 410, which can enhance the structural strength of the first connecting body 410 and reduce the risk of plastic deformation of the first connecting body 410.

[0069] It should be noted that, in this embodiment, the main support rod 200 and the multiple secondary support rods 300 can be configured as circular tubular structures made of metal material. The diameter of the main support rod 200 is larger than the diameter of the secondary support rods 300. The number of secondary support rods 300 can be two, three, four, or other numbers. The connecting rod 100 can be configured as a rectangular tubular structure made of steel. Of course, the present invention does not limit the specific structure of each rod included in the support structure 10.

[0070] Optionally, in one embodiment, the support structure 10 includes a main support rod 200, two secondary support rods 300, and a connecting rod 100. One end of each of the two secondary support rods 300 is connected to the main support rod 200 through the same first connecting node 400, and the other end is connected to two axially spaced positions on the connecting rod 100 through corresponding second connecting nodes 500. The included angle between the two secondary support rods 300 is within the range of 30° to 75°, specifically 30°, 35°, 45°, 60°, 75°, or other angles within the above-mentioned included angle range. This embodiment does not specifically limit this.

[0071] Of course, in another alternative embodiment, the support structure 10 includes a main support rod 200, three secondary support rods 300 and three connecting rods 100. The three secondary support rods 300 and the three connecting rods 100 correspond one-to-one. One end of the three secondary support rods 300 is connected to the main support rod 200 through the same first connecting node 400, and the other end is connected to the corresponding connecting rod 100 through the second connecting node 500 respectively. This embodiment does not limit the specific arrangement of the rods.

[0072] It should be noted that the main support rod 200 of the support structure 10 can extend in a vertical direction or in a direction inclined relative to the vertical direction. This invention does not limit this only. For ease of understanding, the following embodiments will be described with the main support rod 200 extending in a vertical direction as an example.

[0073] Optionally, in one embodiment, the first connecting body 410 located at the first connecting node 400 between a main supporting rod 200 and two secondary supporting rods 300 is configured as a connecting ball 401. The main connecting portion 411 is configured as the lower hemisphere of the connecting ball 401 near the main supporting rod 200, and the secondary connecting portion 412 is configured as the upper hemisphere of the connecting ball 401 near the two secondary supporting rods 300. It should be noted that in this embodiment, the connecting ball 401 can be made of steel, and its diameter is slightly larger than the diameter of the main supporting rod 200.

[0074] Furthermore, the extended axis of the main support rod 200 passes through the center of the connecting ball 401, and the extended axes of the two secondary support rods 300 intersect at a point on the extended axis of the main support rod 200.

[0075] It should be noted that, in this embodiment, the end of the main support rod 200 and the two secondary support rods 300 near the connecting ball 401 is cut to fit the outer surface of the connecting ball 401 and is fixedly connected to the connecting ball 401 by welding.

[0076] In this embodiment, the design of the connecting ball 401 ensures that the first connecting body 410 has the same curvature and strength in all directions, thereby guaranteeing the uniformity of the connection with the main supporting rod 200 and multiple secondary supporting rods 300, reducing the risk of structural damage caused by load concentration, improving the overall durability of the structure, and enabling each secondary supporting rod 300 to evenly distribute the load, further improving the stability of the structure.

[0077] Furthermore, the extension line of the axis of the main support rod 200 passes through the center of the connecting ball 401, so that the main connecting part 411, which is set as a hemispherical surface, can be stably connected to the main support rod 200, further improving the connection stability between the first connecting body 410 and the main support rod 200. The extension lines of the axes of multiple secondary support rods 300 intersect at a point on the extension line of the axis of the main support rod 200. This design makes all secondary support rods 300 form a common intersection point on the connecting ball 401, thereby realizing the concentrated transmission and dispersion of force.

[0078] Furthermore, such as Figure 2 As shown, a first reinforcing plate 402 is provided on the outer periphery of the connecting ball 401 near the supporting main rod 200. The first reinforcing plate 402 extends in a circumferential direction parallel to the supporting main rod 200. A second reinforcing plate 403 is provided on the outer periphery of the supporting main rod 200 near the connecting ball 401. The second reinforcing plate 403 extends in a circumferential direction along the supporting main rod 200.

[0079] Furthermore, the first auxiliary reinforcing component 413 is disposed between the first reinforcing plate 402 and the second reinforcing plate 403, and includes a plurality of reinforcing ribs 404 spaced circumferentially along the main support rod 200. One end of each reinforcing rib 404 is connected to the first reinforcing plate 402, and the other end is connected to the second reinforcing plate 403. It should be noted that in this embodiment, the number of reinforcing ribs 404 can be two, three, four, five, eight, or other numbers. Those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not impose specific limitations in this regard.

[0080] The first reinforcing plate 402 is disposed on the outer periphery of the connecting ball 401 near the supporting main rod 200, increasing the strength and rigidity of the connection area between the connecting ball 401 and the supporting main rod 200; the second reinforcing plate 403 is disposed on the outer periphery of the supporting main rod 200 near the connecting ball 401, enhancing the load-bearing capacity of the supporting main rod 200 in this area.

[0081] The first auxiliary reinforcing component 413 is configured as a plurality of reinforcing ribs 404, which are spaced apart circumferentially along the main support rod 200. One end of each reinforcing rib 404 is connected to the first reinforcing plate 402 and the other end is connected to the second reinforcing plate 403, thereby forming a bridge-like connection between the first reinforcing plate 402 and the second reinforcing plate 403. This not only enhances the connection between the reinforcing plates, but also improves the stability of the overall structure by distributing the load.

[0082] Therefore, this design further enhances the stability and connection strength of the support structure 10, optimizes the load distribution, and improves the overall durability of the structure by setting reinforcing plates on the outer periphery of the connecting ball 401 and the supporting main rod 200, and setting multiple reinforcing ribs 404 between them as the first auxiliary reinforcing component 413.

[0083] In another alternative embodiment, multiple reinforcing plates are spaced apart on the outer periphery of the connecting ball 401 near the supporting main rod 200 and on the outer periphery of the supporting main rod 200 near the connecting ball 401, for example, seven. The first auxiliary reinforcing component 413 is configured as multiple connecting blocks spaced apart along the circumference of the reinforcing plates between two adjacent reinforcing plates, and each connecting block is welded to the corresponding outer surface of the two reinforcing plates.

[0084] Of course, those skilled in the art can design the specific structure of the first auxiliary reinforcement component 413 according to actual conditions and specific needs, and this embodiment does not impose specific limitations on it.

[0085] Optionally, in one embodiment, the first inner reinforcing component 414 includes a plurality of first inner reinforcing plates 405 disposed within the connecting ball 401. It should be noted that two, three, four, or other numbers of first inner reinforcing plates 405 may be disposed within the connecting ball 401, and this embodiment does not specifically limit this.

[0086] In this configuration, each of the multiple first inner reinforcing plates 405 passes through the center of the connecting ball 401, and the outer edge of the first inner reinforcing plate 405 is in contact with the inner surface of the connecting ball 401.

[0087] Optionally, such as Figure 2 As shown, in one embodiment, the connecting ball 401 is provided with a first inner reinforcing plate 405 extending vertically and a first inner reinforcing plate 405 extending horizontally. Of course, the connecting ball 401 may also be provided with a first inner reinforcing plate 405 extending through the axial extension line of the two supporting secondary rods 300 to transmit the internal force between the rods.

[0088] In this embodiment, by incorporating a reinforcing plate inside the connecting ball 401, the load-bearing capacity of the connecting ball 401 can be significantly improved, enabling it to withstand greater loads without failure. Furthermore, the reinforcing plate design enhances the structural stability of the connecting ball 401, ensuring the overall structure maintains good performance even under complex working conditions.

[0089] Furthermore, since the reinforcing plate passes through the center of the ball, it can effectively and evenly transfer the load from the secondary support rod 300 to the main support rod 200, reducing the risk of structural deformation or damage caused by uneven load distribution.

[0090] In another alternative embodiment, the first inner reinforcement component 414 includes a plurality of inner reinforcement rods disposed within the connecting ball 401, the plurality of inner reinforcement rods being parallel to or intersecting each other, thereby forming a grid-like inner reinforcement structure within the connecting ball 401.

[0091] Of course, those skilled in the art can design the specific structure of the first auxiliary reinforcement component 413 according to actual conditions and specific needs, and this embodiment does not impose specific limitations on it.

[0092] Regarding the structure of the first connector 410, it is not limited to the spherical structure in the above embodiments. In another alternative embodiment, the first connector 410 is set as an ellipsoidal structure, or it can be set as a regular octahedron structure. Those skilled in the art can design it according to actual conditions and specific needs. This embodiment does not limit it to a single structure.

[0093] Furthermore, taking the first connecting body 410 as an example of an ellipsoidal structure, the major diameter of the ellipsoid extends vertically and the minor diameter extends horizontally; or the minor diameter of the ellipsoid extends vertically and the major diameter extends horizontally, the outer surface of the ellipsoid near the connecting rod 100 is fixedly connected to multiple secondary supporting rods 300, and the outer surface near the main supporting rod 200 is fixedly connected to the main supporting rod 200.

[0094] When the first connector 410 is set as a regular octahedron structure, the part of the regular octahedron structure near the main support rod 200 is embedded in the main support rod 200 and the end point is aligned with the axis of the main support rod 200. The two opposite surfaces of the regular octahedron structure near the connecting rod 100 are respectively fixedly connected to the corresponding secondary support rod 300.

[0095] Therefore, those skilled in the art can design the specific structure of the first connector 410 according to actual conditions and specific needs, and this embodiment does not impose specific limitations on it.

[0096] To improve the connection strength between the secondary support rod 300 and the connecting rod 100, in one embodiment, such as Figure 3As shown, the second connecting node 500 is provided with a hollow second connecting body 510, and a second inner reinforcing component 511 is provided inside the second connecting body 510.

[0097] The second connecting body 510 is configured as a connecting cylinder 501, the axis of which is perpendicular to the axis of the connecting rod 100. The connecting rod 100 and the multiple supporting secondary rods 300 are all connected to the side wall of the corresponding connecting cylinder 501. It should be noted that this connecting cylinder 501 is made of steel, and its side wall is fixed to the connecting rod 100 and the multiple supporting secondary rods 300 by welding.

[0098] Furthermore, both ends of the connecting cylinder 501 are provided with sealing plates 502. The second inner reinforcing assembly 511 includes a plurality of second inner reinforcing plates 503 disposed within the connecting cylinder 501. The plurality of second inner reinforcing plates 503 are spaced apart along the axial direction of the connecting cylinder 501, and the outer edge of each second inner reinforcing plate 503 is in contact with the inner surface of the side wall of the connecting cylinder 501. It should be noted that the number of second inner reinforcing plates 503 can be two, three, four, or other numbers, and this embodiment does not specifically limit this.

[0099] In this embodiment, by designing a hollow second connector 510 (i.e., a connecting cylinder 501) and providing a second inner reinforcing component 511 inside it, the connection strength between the secondary support rod 300 and the connecting rod 100 can be significantly improved, further enhancing the stability and durability of the entire support structure 10.

[0100] The axis of the connecting cylinder 501 is perpendicular to the axis of the connecting rod 100. This design allows the connecting cylinder 501 to effectively connect the secondary support rod 300 and the connecting rod 100, forming a stable connection structure.

[0101] Specifically, such as Figure 3 As shown, both ends of the connecting cylinder 501 are provided with sealing plates 502, which not only prevents foreign objects from entering the interior of the connecting cylinder 501, but also increases the rigidity and strength of the connecting cylinder 501, further improving the stability of the connection node; multiple second inner reinforcing plates 503 are provided at intervals along the axial direction of the connecting cylinder 501 inside the connecting cylinder 501. This design allows the second inner reinforcing plates 503 to evenly distribute the stress inside the connecting cylinder 501, preventing structural damage caused by excessive local stress.

[0102] Of course, the specific structure of the second connector 510 is not limited to a cylindrical structure, but can also be set as a cuboid structure, a sphere structure or a polygonal prism structure. This embodiment does not limit it to a single structure.

[0103] Furthermore, such as Figure 3As shown, in order to improve the connection strength between the connecting cylinder 501 and the connecting rod 100, a connection reinforcement component 600 is provided at the position where the connecting cylinder 501 and the connecting rod 100 meet.

[0104] The connecting reinforcement assembly 600 includes connecting reinforcement plates 601 disposed on opposite sides of the connecting rod 100. Each connecting reinforcement plate 601 includes a first reinforcement plate segment 602 and a second reinforcement plate segment 603 that are connected to each other. The first reinforcement plate segment 602 is adapted to and connected to the outer surface of the side wall of the connecting cylinder 501, and the second reinforcement plate segment 603 is adapted to and connected to the outer wall of the connecting rod 100. It should be noted that the number of connecting reinforcement plates 601 can be two, three, four, or other numbers; this embodiment does not specifically limit this number.

[0105] Alternatively, in one embodiment, such as Figure 3 As shown, the connecting reinforcement assembly 600 includes two connecting reinforcement plates 601. The two connecting reinforcement plates 601 are located on the side of the connecting cylinder 501 near the supporting secondary rod 300, and are respectively disposed on two opposite side walls of the connecting rod 100.

[0106] In another embodiment, the connecting reinforcement assembly 600 includes four connecting reinforcement plates 601, which are arranged in pairs on both sides of the connecting cylinder 501, with the two connecting reinforcement plates 601 on one side respectively arranged on the two opposite side walls of the connecting rod 100.

[0107] Of course, in another alternative embodiment, the connecting reinforcement assembly 600 includes eight connecting reinforcement plates 601, which are arranged in groups of four on both sides of the connecting cylinder 501, with the four connecting reinforcement plates 601 on one side respectively disposed on the four side walls of the connecting rod 100.

[0108] Of course, in order to improve the connection strength between the secondary support rod 300 and the first connecting body 410 and the second connecting body 510, such as Figure 1 As shown, in one embodiment, both ends of each of the two secondary support rods 300 are fitted onto the reinforcing sleeve 700.

[0109] One end of the secondary support rod 300 is sleeved on the reinforcing sleeve 700, and the reinforcing sleeve 700 is fixedly connected to the first connecting body 410. The other end of the secondary support rod 300 is sleeved on the reinforcing sleeve 700, and the reinforcing sleeve 700 is fixedly connected to the second connecting body 510.

[0110] It should be noted that in this embodiment, the reinforcing sleeve 700 can be a cylindrical structure made of steel. Taking the reinforcing sleeve 700 connecting the first connector 410 as an example, one end of it is connected to the outer surface of the first connector 410 by welding.

[0111] The present invention also discloses a building roof, including a plurality of the above-described support structures 10, wherein the connecting rods 100 of the plurality of support structures 10 are parallel to each other or intersecting.

[0112] In two adjacent and intersecting support structures 10, the connecting rod 100 of one support structure 10 is connected to the connecting rod 100 of the other support structure 10 by a second connecting node 500. Of course, in two adjacent and connected support structures 10, the connecting rod 100 of one support structure 10 can also be parallel to the connecting rod 100 of the other support structure 10, and the two are fixedly connected by their opposite ends.

[0113] Alternatively, in one embodiment, such as Figure 1 As shown, two second connecting nodes 500 are provided on the connecting rod 100 of a support structure 10. Each second connecting node 500 has a second connecting body 510 connected to another connecting rod 100 perpendicular to the extension direction of the connecting rod 100.

[0114] Furthermore, such as Figure 1 As shown, the building roof also includes multiple connecting secondary rods 20, which intersect with the connecting rod 100 and connect to the connecting rod 100 at positions offset from the second connecting node 500. The number of connecting secondary rods 20 can be two, three, four, or other numbers; this embodiment does not specifically limit this.

[0115] It should be noted that in this embodiment, the connecting secondary rod 20 is a rectangular tubular structure made of steel, and its structure is similar to that of the connecting rod 100.

[0116] Alternatively, in one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the connecting rod 100 is connected to the connecting secondary rod 20 extending perpendicular to the direction of the connecting rod 100 on the outside of the two second connecting nodes 500.

[0117] It should be noted that in the building roof provided by this invention, the connecting rod 100, the secondary connecting rod 20, the main supporting rod 200, the secondary supporting rod 300, the first connecting body 410, and the second connecting body 510 can all be made of steel, aluminum alloy, stainless steel, or other metal materials. Furthermore, two of the multiple rods that are connected to each other, such as the connecting rod 100 and the secondary connecting rod 20, the connecting rod 100 and the second connecting body 510, the secondary supporting rod 300 and the second connecting body 510, the secondary supporting rod 300 and the first connecting body 410, and the main supporting rod 200 and the first connecting body 410, can all be connected by welding.

[0118] Furthermore, in order to improve the connection strength between the connecting rod 100 and the connecting secondary rod 20, a reinforcing ring plate 30 is sleeved at the intersection of the connecting rod 100 and the connecting secondary rod 20, and the reinforcing ring plate 30 is attached to the corresponding outer surface of the connecting secondary rod 20.

[0119] In this embodiment, the building roof is composed of multiple support structures 10. The connecting rods 100 of these support structures 10 are parallel and staggered or intersect each other, forming a complex support network. Adjacent and intersecting support structures 10 are connected by second connecting nodes 500 to achieve the intersecting connection of the connecting rods 100. This design enhances the connection strength between the support structures 10 and improves the stability of the overall structure.

[0120] And, as Figure 4 and Figure 5 As shown, the presence of the connecting secondary rod 20 allows the building roof to better distribute loads when subjected to external forces, reducing the risk of structural damage due to excessive local stress. A reinforcing ring plate 30 is fitted at the intersection of the connecting rod 100 and the connecting secondary rod 20, enhancing the connection strength between the connecting rod 100 and the connecting secondary rod 20.

[0121] Therefore, this building roof adopts multiple of the above-mentioned support structures 10 and cleverly arranges connecting rods 100 and connecting secondary rods 20 to achieve efficient support and stable connection of the structure, which can meet various scenarios that need to withstand high loads and complex working conditions.
