Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a supporting structure which can be used for a building roof. Background Art

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

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

[0004] The single-layer grid structure system supported by the tree-like structure has been favored in the spatial structure design in recent years due to its advantages such as simple and beautiful architectural shape and strong adaptability to free-form surfaces. The single-layer grid structure has a small number of rods, and the structure is often exposed in engineering applications, which has rich architectural expression, and the building and structure complement each other. However, everything has two sides. The single-layer grid structure also has the problems of poor structural stiffness and poor stability due to the small number of rods and small structural rise ratio.

[0005] For example, a Chinese patent document (publication number CN217870962U) discloses an integral variable-section tree branch column expansion support structure, including a column and a tree branch beam, which is evenly fixed on the outer surface of the column in the circumferential direction. The tree branch beam is divided into support section 1 and support section 2, support section 1 is arranged between the column and support section 2, support section 2 is used to support the steel structure, and the cross-sectional area of ​​support section 1 gradually increases along the direction from support section 2 to the column. This support structure increases the cross-sectional moment of inertia and improves the bending bearing capacity by changing the cross-section of the tree branch beam.

[0006] However, the columns and branch cantilever beams of this supporting structure are directly welded. When the load received by the branch cantilever beams is transferred to the columns, the horizontal forces of multiple branch cantilever beams offset each other, and the connection between the columns and the branch cantilever beams is subject to great shear stress. Excessive shear stress is very likely to separate the columns and the branch cantilever beams from the connection. Summary of the invention

[0007] The purpose of the present invention is to solve the technical problem that the columns and branch cantilever beams of the supporting structure are directly welded in the prior art. When the load received by the branch cantilever beam is transferred to the column, the connection between the column and the branch cantilever beam is subjected to great shear stress. The excessive shear stress is very likely to separate the column and the branch cantilever beam from the connection.

[0008] In order to solve the above technical problems, an embodiment of the present invention discloses a support structure, which includes a connecting rod, a supporting main rod, and multiple supporting secondary rods, one end of each of the multiple supporting secondary rods is connected to one end of the supporting main rod at a first connecting node, and the multiple supporting secondary rods extend divergently from their respective ends and are connected to the connecting rod at a second connecting node.

[0009] Among them, the first connection node is provided with a hollow first connection body, the first connection body has a main connection part and a secondary connection part arranged oppositely, one end of the supporting main rod is connected to the main connection part, and one end of multiple supporting secondary rods are connected to the secondary connection part.

[0010] Furthermore, a first auxiliary reinforcement component is disposed on the outer periphery of the main connection portion of the first connecting body, and a first inner reinforcement component is disposed inside the first connecting body.

[0011] By adopting the above technical scheme, this support structure supports the connecting rod through the supporting main rod and multiple supporting secondary rods, wherein the connecting rod can bear the covering components of the building roof or be directly exposed to the outside, the supporting main rod serves as the main supporting component, and its end away from the connecting rod is fixedly connected to the bearing platform (such as the ground), and multiple supporting secondary rods are arranged between the supporting main rod and the connecting rod, one end of the multiple supporting secondary rods is connected to one end of the supporting main rod at a first connecting node, and extends in a divergent shape, so that the supporting main rod and the multiple supporting secondary rods form a tree-like structure. Specifically, the supporting main rod is similar to the trunk in the tree branch structure, and the multiple supporting secondary rods are similar to the branches in the tree-like structure. The connecting rod is connected to the multiple supporting secondary rods through the second connecting node, and the load it receives is applied to the supporting secondary rod through the second connecting node, and the supporting secondary rod transfers the load to the supporting main rod through the first connecting node. The dispersed arrangement not only makes the loads of the multiple supporting secondary rods partially offset at the first connecting node, disperses the external force, and reduces the impact force on the single supporting secondary rod, but also makes the supporting main rod evenly stressed in the circumferential direction, thereby improving the stability of the supporting structure.

[0012] Among them, a hollow first connector is arranged at the first connection node, and the first connector is connected to the supporting main rod through a main connecting part, and is connected to multiple supporting secondary rods through a secondary connecting part. Compared with the direct welding method in the prior art, the first connector greatly improves the connection strength and stability between the supporting main rod and the multiple supporting secondary rods. Moreover, the hollow first connector can achieve lightweight requirements and reduce the load on the supporting main rod while ensuring the connection strength.

[0013] Furthermore, the first auxiliary reinforcement component arranged on the periphery of the main connection part can enhance the connection strength between the main connection part and the supporting main rod, and prevent connection failure caused by excessive force; and the first internal reinforcement component located inside the first connection body can enhance the structural strength of the first connection body and reduce the risk of plastic deformation of the first connection body.

[0014] Optionally, in one embodiment, the first connector is configured as a connecting ball, the main connecting part is configured as a hemispherical surface of the connecting ball close to the side supporting the main rod, and the secondary connecting part is configured as a hemispherical surface of the connecting ball close to the side supporting multiple secondary rods.

[0015] In addition, the axis extension line of the supporting main rod passes through the center of the connecting ball, and the axis extension lines of the plurality of supporting secondary rods intersect at a point of the axis extension line of the supporting main rod.

[0016] By adopting the above technical solution, the design of the connecting ball enables the first connector to have the same curvature and strength in all directions, thereby ensuring the uniformity of the connection with the supporting main rod and multiple supporting secondary rods, reducing the risk of structural damage due to load concentration, and improving the durability of the overall structure. At the same time, each supporting secondary rod can evenly share the load, further improving the stability of the structure.

[0017] In addition, the axial extension line of the supporting main rod passes through the center of the connecting ball, so that the main connecting part set as a hemispherical surface can be stably connected to the supporting main rod, further improving the connection stability between the first connector and the supporting main rod. The axial extension lines of multiple supporting secondary rods intersect at one point of the axial extension line of the supporting main rod. This design enables all the supporting secondary rods to form a common intersection point on the connecting ball, thereby realizing centralized transmission and dispersion of force.

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

[0019] Furthermore, the first auxiliary reinforcement assembly is arranged between the first reinforcement plate and the second reinforcement plate, and includes a plurality of reinforcement ribs arranged at intervals along the circumference of the supporting main rod, one end of each of the plurality of reinforcement ribs is connected to the first reinforcement plate, and the other end is connected to the second reinforcement plate.

[0020] By adopting the above technical solution, the first reinforcement plate is arranged on the outer periphery of the connecting ball close to the supporting main rod, thereby increasing the strength and rigidity of the connection area between the connecting ball and the supporting main rod; the second reinforcement plate is arranged on the outer periphery of the supporting main rod close to the connecting ball, thereby enhancing the bearing capacity of the supporting main rod in this area.

[0021] The first auxiliary reinforcement component is configured as a plurality of reinforcement ribs, and the plurality of reinforcement ribs are arranged at intervals along the circumference of the supporting main rod. One end of each reinforcement rib is connected to the first reinforcement plate, and the other end is connected to the second reinforcement plate, thereby forming a bridge-like connection between the first reinforcement plate and the second reinforcement plate, which not only strengthens the connection between the reinforcement plates, but also improves the stability of the overall structure by dispersing the load.

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

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

[0024] Each of the plurality of first inner reinforcing plates passes through the center of the connecting ball, and the outer edge of the first inner reinforcing plate is connected to the inner surface of the connecting ball.

[0025] By adopting the above technical solution, by setting a reinforcement plate inside the connection ball, the bearing capacity of the connection ball can be significantly improved, so that it can withstand a larger load without being damaged. In addition, the design of the reinforcement plate enhances the structural stability of the connection ball, so that the overall structure can maintain good performance even under complex working conditions.

[0026] In addition, since the reinforcing plate passes through the center of the sphere, the load from the supporting secondary rod can be effectively and evenly transferred to the supporting main 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 reinforcement component is provided inside the second connecting body.

[0028] The second connecting body is configured as a connecting tube, the axial direction of the connecting tube is perpendicular to the axial direction of the connecting rod, and the connecting rod and a plurality of supporting secondary rods are all connected to the side walls of the corresponding connecting tube.

[0029] In addition, sealing plates are provided at both ends of the connecting tube. The second internal reinforcement assembly includes multiple second internal reinforcement plates arranged in the connecting tube. The multiple second internal reinforcement plates are arranged at intervals along the axial direction of the connecting tube, and the outer edge of each second internal reinforcement plate is connected to the inner surface of the side wall of the connecting tube.

[0030] By adopting the above technical solution, by designing a hollow second connector (ie, a connecting tube) and arranging a second inner reinforcement component inside it, the connection strength between the supporting secondary rod and the connecting rod can be significantly improved, further enhancing the stability and durability of the entire supporting structure.

[0031] The axial direction of the connecting tube is perpendicular to the axial direction of the connecting rod. This design enables the connecting tube to effectively connect the supporting secondary rod and the connecting rod to form a stable connection structure.

[0032] Specifically, sealing plates are provided at both ends of the connecting tube, which can not only prevent debris from entering the interior of the connecting tube, but also increase the rigidity and strength of the connecting tube, and further improve the stability of the connecting node; a plurality of second inner reinforcing plates are arranged at intervals along the axial direction of the connecting tube in the connecting tube. This design enables the second inner reinforcing plates to evenly disperse the stress inside the connecting tube, and prevent structural damage caused by excessive local stress.

[0033] The embodiment of the present invention further discloses a building roof, comprising a plurality of the above-mentioned supporting structures, wherein the connecting rods of the plurality of supporting structures are parallel to each other, staggered or intersecting.

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

[0035] Furthermore, the building roof also includes a plurality of secondary connecting rods, which are staggered with the connecting rod and connected at positions on the connecting rod that are staggered from the second connecting node.

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

[0037] With the above technical solution, the building roof is composed of multiple supporting structures, and the connecting rods of these supporting structures are parallel, staggered or intersecting with each other, forming a complex supporting network. Adjacent and intersecting supporting structures realize the intersection connection of the connecting rods through the second connecting node. This design enhances the connection strength between the supporting structures and improves the stability of the overall structure.

[0038] In addition, the presence of the secondary connecting rod enables the building roof to better disperse the load when subjected to external forces, reducing the risk of structural damage caused by excessive local stress. A reinforcing ring plate is sleeved at the intersection of the connecting rod and the secondary connecting rod to enhance the connection strength between the connecting rod and the secondary connecting rod.

[0039] Therefore, this building roof adopts multiple of the above-mentioned support structures and cleverly arranges connecting rods and connecting secondary 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 the prior art, the columns and branch cantilever beams of the supporting structure are directly welded. When the load received by the branch cantilever beams is transferred to the columns, the horizontal forces of multiple branch cantilever beams offset each other, and the connection between the columns and the branch cantilever beams is subject to great shear stress. Excessive shear stress is very likely to separate the columns and the branch cantilever beams from the connection.

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

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

[0061] Moreover, this structural form can make more effective use of materials. Through reasonable branch design, it can save material usage and reduce the deadweight of the structure while ensuring structural strength, which is beneficial to the cost control of the entire structural system.

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

[0063] Furthermore, in order to improve the connection strength between the multiple supporting secondary rods and the supporting main rod, the supporting structure provided by the present invention provides a hollow first connector at the first connection node. The first connector not only connects the supporting secondary rods and the supporting main 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 reinforcement component is provided on the periphery of the main connection portion of the first connector, and a first inner reinforcement component is provided inside the first connector.

[0065] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in 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 supporting main rod 200, and a plurality of supporting secondary rods 300, wherein the connecting rod 100 can bear the covering components of the building roof or be directly exposed to the outside, the supporting main rod 200 serves as the main supporting component, and its end away from the connecting rod 100 is fixedly connected to a bearing platform (such as the ground), and a plurality of supporting secondary rods 300 are arranged between the supporting main rod 200 and the connecting rod 100, and one end of the plurality of supporting secondary rods 300 is connected to one end of the supporting main rod 200 at a first connection node 400, and extends in a divergent shape, so that the supporting main rod 200 and the plurality of supporting secondary rods 300 form a tree structure. Specifically, the main support rod 200 is similar to a trunk in a branch structure, and the multiple secondary support rods 300 are similar to branches in a tree structure. The connecting rod 100 is connected to the multiple secondary support rods 300 through the second connection node 500. The load it receives is applied to the secondary support rod 300 through the second connection node 500, and the secondary support rod 300 transfers the load to the main support rod 200 through the first connection node 400. The dispersed arrangement not only allows the loads of the multiple secondary support rods 300 to be partially offset at the first connection node 400, dispersing external forces and reducing impact forces on a single secondary support rod 300, but also allows the main support rod 200 to be uniformly stressed in the circumferential direction, thereby improving the stability of the support structure 10.

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

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

[0069] It should be noted that, in this embodiment, the main support rod 200 and multiple secondary support rods 300 can be set as a circular tubular structure made of metal material, the diameter of the main support rod 200 is larger than the diameter of the secondary support rod 300, the number of secondary support rods 300 can be two, three, four or other numbers, and the connecting rod 100 can be set as a rectangular tubular structure made of steel. Of course, the present invention does not make a sole limitation on 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 the two secondary support rods 300 is connected to the main support rod 200 through the same first connection node 400, and the other ends are connected to two axially spaced positions on the connecting rod 100 through corresponding second connection nodes 500, respectively. The angle between the two secondary support rods 300 is in the range of 30° to 75°, and can specifically be 30°, 35°, 45°, 60°, 75° or other angles within the above angle range, and this embodiment does not make any specific limitation on this.

[0071] Of course, in another alternative embodiment, the support structure 10 includes a supporting main rod 200, three supporting secondary rods 300 and three connecting rods 100, the three supporting secondary rods 300 and the three connecting rods 100 correspond one to one, one end of the three supporting secondary rods 300 is connected to the supporting main 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. Regarding the specific setting of the rod members, this embodiment does not make a sole limitation on this.

[0072] It should be noted that the main support rod 200 of the support structure 10 can extend in the vertical direction or in a direction inclined relative to the vertical direction. The present invention does not make a sole limitation on this. For ease of understanding, the following embodiments are described by taking the main support rod 200 extending in the vertical direction as an example.

[0073] Optionally, in one embodiment, the first connector 410 of the first connection node 400 between a supporting main rod 200 and two supporting secondary rods 300 is configured as a connecting ball 401, the main connecting portion 411 is configured as a lower hemispherical surface of the connecting ball 401 close to the supporting main rod 200, and the secondary connecting portion 412 is configured as an upper hemispherical surface of the connecting ball 401 close to the two supporting secondary 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 pipe diameter of the supporting main rod 200.

[0074] Furthermore, the axis extension line of the supporting main rod 200 passes through the center of the connecting ball 401 , and the axis extension lines of the two supporting secondary rods 300 intersect at a point of the axis extension line of the supporting main rod 200 .

[0075] It should be noted that, in this embodiment, the ends of the supporting main rod 200 and the two supporting secondary rods 300 close to the connecting ball 401 are cut into ends adapted to the outer surface of the connecting ball 401, and are fixedly connected to the connecting ball 401 by welding.

[0076] In this embodiment, the design of the connecting ball 401 enables the first connecting body 410 to have the same curvature and strength in all directions, thereby ensuring the uniformity of the connection with the supporting main rod 200 and multiple supporting secondary rods 300, reducing the risk of structural damage due to load concentration, and improving the durability of the overall structure. At the same time, each supporting secondary rod 300 can evenly share the load, further improving the stability of the structure.

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

[0078] Further, if Figure 2 As shown, a first reinforcement plate 402 is arranged on the periphery of the connecting ball 401 near the supporting main rod 200, and the first reinforcement plate 402 extends in a circumferential direction parallel to the supporting main rod 200. A second reinforcement plate 403 is arranged on the periphery of the supporting main rod 200 near the connecting ball 401, and the second reinforcement plate 403 extends in the circumferential direction of the supporting main rod 200.

[0079] Furthermore, the first auxiliary reinforcement assembly 413 is disposed between the first reinforcement plate 402 and the second reinforcement plate 403, and includes a plurality of reinforcement ribs 404 spaced apart along the circumference of the support main rod 200, and one end of each of the plurality of reinforcement ribs 404 is connected to the first reinforcement plate 402, and the other end is connected to the second reinforcement plate 403. It should be noted that in this embodiment, the number of the reinforcement ribs 404 can be two, three, four, five, eight or other numbers, and those skilled in the art can design according to actual conditions and specific needs, and this embodiment does not specifically limit this.

[0080] Among them, the first reinforcement plate 402 is arranged on the outer periphery of the connecting ball 401 on the side close to the supporting main rod 200, thereby increasing the strength and rigidity of the connection area between the connecting ball 401 and the supporting main rod 200; the second reinforcement plate 403 is arranged on the outer periphery of the supporting main rod 200 on the side close to the connecting ball 401, thereby enhancing the bearing capacity of the supporting main rod 200 in this area.

[0081] The first auxiliary reinforcement component 413 is configured as a plurality of reinforcement ribs 404, and the plurality of reinforcement ribs 404 are arranged at circumferential intervals along the supporting main rod 200, and one end of each reinforcement rib 404 is connected to the first reinforcement plate 402, and the other end is connected to the second reinforcement plate 403, so that a bridge-like connection is formed between the first reinforcement plate 402 and the second reinforcement plate 403, which not only strengthens the connection between the reinforcement plates, but also improves the stability of the overall structure by dispersing 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 durability of the overall structure by respectively setting reinforcement plates on the periphery of the connecting ball 401 and the supporting main rod 200, and setting multiple reinforcing ribs 404 between the two as the first auxiliary reinforcement component 413.

[0083] In another alternative embodiment, multiple reinforcement plates, for example, seven, are arranged at intervals on the outer periphery of the connecting ball 401 near the supporting main rod 200 and the outer periphery of the supporting main rod 200 near the connecting ball 401, wherein the first auxiliary reinforcement component 413 is arranged between two adjacent reinforcement plates, and multiple connecting blocks are arranged at intervals along the circumference of the reinforcement plates, and each connecting block is welded to the corresponding outer surfaces of the two reinforcement plates.

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

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

[0086] Each of the plurality of 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 connected to the inner surface of the connecting ball 401 .

[0087] Alternatively, if Figure 2 As shown, in one embodiment, a first inner reinforcing plate 405 extending in the vertical direction and a first inner reinforcing plate 405 extending in the horizontal direction are provided in the connecting ball 401. Of course, a first inner reinforcing plate 405 passing through the axis extension line of the two supporting secondary rods 300 can also be provided in the connecting ball 401 to transmit the internal force between the rods.

[0088] In this embodiment, by providing a reinforcement plate inside the connection ball 401, the bearing capacity of the connection ball 401 can be significantly improved, so that it can withstand a larger load without being damaged. In addition, the design of the reinforcement plate enhances the structural stability of the connection ball 401, so that the overall structure can maintain good performance even under complex working conditions.

[0089] In addition, since the reinforcing plate passes through the center of the sphere, the load from the supporting secondary rod 300 can be effectively and evenly transferred to the supporting main 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 in the connecting ball 401 , the plurality of inner reinforcement rods are parallel to or intersecting with each other, thereby forming a grid-like inner reinforcement structure in the connecting ball 401 .

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

[0092] The structure of the first connector 410 is not limited to the spherical structure in the above embodiment. In another alternative embodiment, the first connector 410 is set to an ellipsoidal structure or a regular octahedron structure. Those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not make a sole limitation on this.

[0093] Further, taking the example of the first connector 410 being set as an ellipsoid structure, the long diameter of the ellipsoid extends in the vertical direction, and the short diameter extends in the horizontal direction; or the short diameter of the ellipsoid extends in the vertical direction, and the long diameter extends in the horizontal direction, and the outer surface of the ellipsoid close to the connecting rod 100 is fixedly connected to a plurality of supporting secondary rods 300, and the outer surface close to the supporting main rod 200 is fixedly connected to the supporting main rod 200.

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

[0095] Therefore, regarding the specific structure of the first connector 410 , those skilled in the art may design it according to actual conditions and specific requirements, and this embodiment does not make any specific limitation on this.

[0100] The axial direction of the connecting tube 501 is perpendicular to the axial direction of the connecting rod 100. This design enables the connecting tube 501 to effectively connect the supporting secondary rod 300 and the connecting rod 100 to form a stable connection structure.

[0101] Specifically, Figure 3 As shown, sealing plates 502 are provided at both ends of the connecting tube 501, which can not only prevent debris from entering the interior of the connecting tube 501, but also increase the rigidity and strength of the connecting tube 501, and further improve the stability of the connection node; a plurality of second inner reinforcing plates 503 are arranged at intervals in the connecting tube 501 along the axial direction of the connecting tube 501. This design enables the second inner reinforcing plates 503 to evenly disperse the stress inside the connecting tube 501, and prevent 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 may also be a rectangular parallelepiped structure, a spherical structure or a polygonal column structure, and this embodiment does not make the sole limitation thereto.

It should be noted that the number of the connection reinforcement plates 601 can be two, three, four or other numbers, and this embodiment does not specifically limit this.

[0105] Optionally, in one embodiment, Figure 3 As shown, the connection reinforcement assembly 600 includes two connection reinforcement plates 601 , which are located on one side of the connection tube 501 close to the supporting secondary rod 300 and are respectively arranged on two opposite side walls of the connection rod 100 .

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

[0109] Among them, one end of the supporting secondary rod 300 is sleeved on the reinforcement sleeve 700, and the reinforcement sleeve 700 is fixedly connected to the first connecting body 410. The other end of the supporting secondary rod 300 is sleeved on the reinforcement sleeve 700, and the reinforcement sleeve 700 is fixedly connected to the second connecting body 510.

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

[0120] And, if Figure 4 and Figure 5 As shown, the presence of the secondary connecting rod 20 enables the building roof to better disperse the load when subjected to external force, reducing the risk of structural damage caused by excessive local stress.
