Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to a space frame support. Background Technology

[0002] Space frame structures, as a common spatial load-bearing system, are widely used in the roof systems of large-span buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, and aircraft hangars. During the construction and use of space frame structures, the supports, as key components connecting the space frame and the lower supporting structure, directly affect the overall safety and construction efficiency of the project due to their structural stability, ease of installation, and operability of later maintenance.

[0003] Currently, most common space frame supports on the market use welding or integral casting to fix the mounting base to the base plate. Although such structures have a certain load-bearing capacity under static loads, they have obvious defects in actual engineering. For example, once the integral structure is installed, it is difficult to disassemble or replace, which is not conducive to later maintenance, adjustment or structural modification, and increases maintenance costs and construction difficulty. Although some existing supports use bolt connections to achieve detachable functions, their connection structure is complex, the positioning accuracy is poor, and multiple adjustments are required during disassembly and assembly, making the operation cumbersome. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a space frame support, which solves the technical problem that the space frame support body is inconvenient to disassemble, which leads to difficulties in subsequent maintenance, adjustment or structural modification.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a space frame support, comprising:

[0007] Base plate;

[0008] A cylindrical body is installed at the center of the base plate. Multiple moving slots are arranged around the circumference of the cylindrical body on the base plate. Multiple positioning slots are opened on the outer circumference of the cylindrical body.

[0009] The fastening mechanism includes a positioning rod and a limiting ring. The bottom of the positioning rod is slidably connected to the moving groove and abuts against the positioning groove on the outer periphery of the cylinder. The limiting ring is detachably connected to the base plate and is used to limit the positioning rod in the moving groove.

[0010] The mounting base has a base at its bottom, which is detachably connected to the cylinder. A connecting rod is fixed to the upper end of the mounting base, and a space frame bolt ball is fixed to the upper end of the connecting rod.

[0011] In some embodiments, the base plate is a circular plate, and a plurality of extension plates are arranged circumferentially on the outer periphery of the base plate, and fastening bolts are provided on any one of the extension plates.

[0012] In some embodiments, a plurality of anchor bolts are arranged circumferentially at the lower end of the base plate.

[0013] In some embodiments, the cylinder has an internal cavity, and the inner wall of the cavity is provided with an annular inner extension plate. The inner extension plate is circumferentially arranged with a plurality of protruding columns, and a base is provided on the protruding columns.

[0014] In some embodiments, a buffer element is provided inside the cavity. The buffer element includes a spring strip and a support plate. The lower end of the spring strip is connected to the inner wall of the cylinder, and the upper end is connected to the support plate. A groove is provided on the support plate, and a base is provided in the groove.

[0015] In some embodiments, at least three first connecting screw holes are arranged circumferentially on the upper end of the cylinder, and the lower end of the mounting base is provided with second connecting screw holes corresponding one-to-one with the first connecting screw holes.

[0016] In some embodiments, the positioning rod is an L-shaped rod, and a reinforcing plate is provided on the side of the positioning rod facing away from the cylinder. A sliding block is fixed at the lower end of the positioning rod, and the sliding block is slidably connected to the moving groove.

[0017] In some embodiments, both the limiting ring and the base plate are provided with a plurality of fastening screw holes in the circumferential direction. The lower end of the limiting ring is engaged with the positioning rod, and a limiting block is also fixed to the lower end of the limiting ring. The limiting block is disposed in the moving groove and is used to limit the end of the sliding block.

[0018] In some embodiments, the lower end of the base is provided with a mounting groove that mates with the protruding post.

[0019] In some embodiments, a base post is fixed to the lower end of the base, and the base post is connected to a groove in the support plate.

[0020] Compared with existing technologies, this utility model provides a space frame support where the mounting base is detachably connected to the cylinder body via its bottom base, eliminating the need for welding or integral casting. This allows for quick assembly or replacement of the connecting rods and space frame bolt balls on the upper part of the support, significantly improving on-site construction efficiency and ease of subsequent maintenance. The cylinder body is installed at the center of the base plate, and a fastening mechanism achieves circumferential positioning and axial limiting of the cylinder body. Specifically, the positioning rod is slidably disposed in a moving groove on the base plate and abuts against a positioning groove on the outer circumference of the cylinder body, forming an effective radial constraint on the cylinder body. A limiting ring is detachably connected to the base plate to lock the position of the positioning rod in the moving groove, preventing displacement or loosening during use, thereby ensuring a stable connection between the cylinder body and the base plate. The entire support consists of a base plate, cylinder body, fastening mechanism, and mounting base. Composed of independent components, with detachable connections between them, this design facilitates transportation and storage. It also allows for flexible replacement of mounting bases or cylinders of different specifications to meet specific engineering needs, enhancing the product's versatility and adaptability. The cooperation between the moving groove and the positioning groove ensures that the positioning rod automatically aligns and abuts against the positioning groove on the outer circumference of the cylinder after sliding into the moving groove, achieving precise circumferential positioning of the cylinder on the base plate. The limiting ring further secures this positioning, preventing misalignment due to vibration or external forces and ensuring the reliability of the overall support assembly. Since the space frame bolt ball is fixed to the upper end of the mounting base via a connecting rod, and the mounting base can be detachably installed into the cylinder, the connection between the space frame node and the support can be pre-assembled in the factory. On-site installation only requires fixing the base plate and inserting the mounting base, facilitating prefabricated construction and improving the consistency of project quality.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a space frame support in one embodiment of the present invention. The space frame support includes:

[0030] Base plate 1;

[0031] The cylinder 2 is installed at the center of the base plate 1. Multiple moving slots 11 are arranged around the cylinder 2 on the base plate 1, and multiple positioning slots 21 are opened on the outer circumference of the cylinder 2.

[0032] The fastening mechanism 3 includes a positioning rod 31 and a limiting ring 32. The bottom of the positioning rod 31 is slidably connected to the moving groove 11 and abuts against the positioning groove 21 on the outer periphery of the cylinder 2. The limiting ring 32 is detachably connected to the bottom plate 1 and is used to limit the positioning rod 31 in the moving groove 11.

[0033] Mounting base 4 has a base 41 at its bottom, which is detachably connected to the cylinder 2. A connecting rod 42 is fixed at the upper end of the mounting base 4, and a grid bolt ball 43 is fixed at the upper end of the connecting rod 42.

[0034] In this embodiment, the mounting base 4 is detachably connected to the cylinder 2 via its base 41 at the bottom, without the need for welding or integral casting. This allows for quick assembly or replacement of the connecting rod 42 and the space frame bolt ball 43 on the upper part of the support, significantly improving on-site construction efficiency and the convenience of subsequent maintenance. The cylinder 2 is installed at the center of the base plate 1, and the circumferential positioning and axial limiting of the cylinder 2 are achieved through the fastening mechanism 3. Specifically, the positioning rod 31 is slidably disposed in the moving groove 11 on the base plate 1 and abuts against the positioning groove 21 on the outer periphery of the cylinder 2, forming an effective radial constraint on the cylinder 2. The limiting ring 32 is detachably connected to the base plate 1 to lock the position of the positioning rod 31 in the moving groove 11, preventing displacement or loosening during use, thereby ensuring a stable connection between the cylinder 2 and the base plate 1. The entire support consists of independent components such as the base plate 1, the cylinder 2, the fastening mechanism 3, and the mounting base 4. The components are detachably connected, which not only facilitates transportation and storage, but also allows for flexible replacement of different specifications of mounting base 4 or cylinder 2 according to actual engineering needs, improving the product's versatility and adaptability. The cooperation between the moving groove 11 and the positioning groove 21 allows the positioning rod 31 to automatically align and abut against the positioning groove 21 on the outer circumference of the cylinder 2 after sliding into the moving groove 11, achieving precise circumferential positioning of the cylinder 2 on the base plate 1. The setting of the limiting ring 32 further locks this positioning state, avoiding misalignment caused by vibration or external force, and ensuring the reliability of the overall assembly of the support. Since the space frame bolt ball 43 is fixed to the upper end of the mounting base 4 through the connecting rod 42, and the mounting base 4 can be detachably installed into the cylinder 2, the connection between the space frame node and the support can be pre-assembled in the factory. On-site, only the fixing of the base plate 1 and the insertion of the mounting base 4 need to be completed, which is conducive to realizing prefabricated construction and improving the consistency of project quality.

[0035] In one embodiment, please refer to Figure 1 - Figure 4 To improve the stability of the base plate 1, the base plate 1 is a circular plate, and multiple extension plates 12 are arranged around the outer periphery of the base plate 1. Each extension plate 12 is provided with a fastening bolt 121, and multiple anchor rods 13 are arranged around the lower end of the base plate 1.

[0036] In this embodiment, multiple anchor rods 13 arranged circumferentially at the lower end of the base plate 1 can be pre-embedded or post-anchored in the concrete foundation, forming a reliable pull-out and shear-resistant connection. This effectively resists the upward pull and horizontal thrust generated by the space frame structure under wind load, seismic action, or asymmetrical load, significantly improving the overall overturning resistance and structural safety of the support. The dual fixation of the anchor rods 13, the extension plate 12, and the fastening bolts 121 forms a composite connection between the support and the foundation, with the anchor rods 13 bearing the main vertical and horizontal loads, while the fastening bolts 121 on the extension plate 12 are used for auxiliary positioning, fine-tuning, and additional fastening. The two complement each other, avoiding overall instability caused by the failure of a single connection method. The extension plates 12 are evenly arranged circumferentially along the outer periphery of the base plate 1, allowing the fastening bolts 121 to constrain and fine-tune the base plate 1 in multiple directions. During construction, the levelness correction and precise positioning of the base plate 1 can be achieved by adjusting the fastening bolts 121 on each extension plate 12, especially... Suitable for uneven or construction-error-prone foundation surfaces, improving installation accuracy, the circular base plate 1 itself has good isotropic mechanical properties. Combined with the circumferentially evenly distributed anchor bolts 13 and extension plates 12, the load can be evenly transferred from the cylinder 2 through the base plate 1 to the foundation, effectively dispersing concentrated stress, reducing the risk of warping or cracking at the edge of the base plate 1, and extending the service life of the support. The fastening bolts 121 on the extension plate 12 adopt a detachable connection method, which does not require welding, making it easy to disassemble the support as a whole during later maintenance, replacement or structural modification. At the same time, the anchor bolts 13 provide foundation anchoring guarantee. Even if the bolts of the extension plate 12 are loosened, the support still maintains its basic positioning, avoiding complete instability, and balancing safety and maintainability. The extension plates 12 are integrated into the outer periphery of the circular base plate 1, without significantly increasing the overall projected area of ​​the support, saving space. At the same time, the number and position of the extension plates 12 can be flexibly adjusted according to project needs, adapting to foundations of different sizes or connection hole positions, with good engineering adaptability and standardization potential.

[0037] In one embodiment, please refer to Figure 4 - Figure 6 To improve the buffering effect inside the cylinder 2, a cavity is provided inside the cylinder 2, and an annular inner extension plate 22 is provided on the inner wall of the cavity. Multiple protruding columns 221 are arranged circumferentially on the inner extension plate 22, and a base 41 is provided on the protruding column 221. A buffer component 23 is provided inside the cavity. The buffer component 23 includes a spring strip 231 and a bearing plate 232. The lower end of the spring strip 231 is connected to the inner wall of the cylinder 2, and the upper end is connected to the bearing plate 232. A groove 233 is provided on the bearing plate 232, and a base 41 is provided in the groove 233. At least three first connecting screw holes 24 are arranged circumferentially on the upper end of the cylinder 2, and the lower end of the mounting base 4 is provided with second connecting screw holes 401 corresponding to the first connecting screw holes 24.

[0038] In this embodiment, the inner cavity of the cylinder 2 is simultaneously provided with a protruding post 221 on the inner extension plate 22 and a groove 233 on the bearing plate 232 of the buffer component 23. The base 41 can simultaneously cooperate with the protruding post 221 and the groove 233 to form a dual positioning structure with upper and lower coordination. This not only improves the installation accuracy of the base 41 in the cylinder 2, but also effectively prevents it from deflecting, slipping or loosening during use, significantly enhancing the overall stability of the mounting base 4. The buffer component 23 is composed of a spring strip 231 and a bearing plate 232. The spring strip 231 is connected between the inner wall of the cylinder 2 and the bearing plate 232, so that the mounting base... The dynamic loads borne by the support, such as the impact caused by wind vibration, earthquake, or temperature deformation, can be absorbed and dissipated through the elastic deformation of the spring strip 231. This buffer structure effectively reduces the rigid impact between the support and the foundation, reduces structural fatigue damage, and extends the service life of the space frame system. The mounting base 4 is placed in the groove 233 of the bearing plate 232 through its base 41 and is positioned by the protruding column 221 without welding or complex fastening operations. At the same time, the upper end of the cylinder 2 is provided with at least three first connecting screw holes 24, and the lower end of the mounting base 4 is provided with corresponding second connecting screw holes 401. The two can be connected by bolts. The fast and reliable detachable connection, with a structure that balances positioning accuracy and assembly efficiency, is particularly suitable for engineering scenarios requiring frequent maintenance or replacement. The load of the space frame is transferred to the bearing plate 232 via the connecting rod 42, mounting base 4, and base 41, and then distributed to the inner wall of the cylinder 2 via the spring strip 231, and finally transferred to the bottom plate 1 and foundation by the cylinder 2. This path is clear and continuous, and the presence of the buffer 23 makes the vertical load distribution more uniform, avoiding local stress concentration. It can maintain good working performance, especially under dynamic load or uneven settlement conditions. The groove 233 on the bearing plate 232 forms a circumferential limit for the base 41. To prevent lateral displacement during the compression or rebound of the spring strip 231, the protruding column 221 on the inner extension plate 22 further constrains the bottom of the base 41, providing a buffer function while ensuring that the mounting seat 4 will not detach or become unstable, thus balancing flexibility and safety. The upper end of the cylinder 2 is provided with no less than three first connecting screw holes 24, which correspond one-to-one with the second connecting screw holes 401 at the lower end of the mounting seat 4, forming a multi-point annular connection. This arrangement not only provides sufficient anti-torsion and anti-shear capabilities, but also effectively prevents the mounting seat 4 from rotating or loosening during use, which is significantly better than single-point or two-point connection structures.

[0039] In one embodiment, please refer to Figure 1 - Figure 6To improve the overall installation and dismantling efficiency, the positioning rod 31 is an L-shaped rod, and a reinforcing plate 311 is provided on the side of the positioning rod 31 facing away from the cylinder 2. A sliding block 312 is fixed to the lower end of the positioning rod 31, and the sliding block 312 is slidably connected in the moving groove 11. Multiple fastening screw holes 321 are provided circumferentially on the limiting ring 32 and the base plate 1. The lower end of the limiting ring 32 is engaged with the positioning rod 31, and a limiting block 323 is also fixed to the lower end of the limiting ring 32. The limiting block 323 is set in the moving groove 11 and is used to limit the end of the sliding block 312. An assembly groove 411 that cooperates with the protruding column 221 is provided circumferentially on the lower end of the base 41. A bottom column 412 is fixed to the lower end of the base 41, and the bottom column 412 is connected in the groove 233 of the bearing plate 232.

[0040] In this embodiment, the positioning rod 31 adopts an L-shaped rod structure. Its vertical section abuts against the positioning groove 21 on the outer periphery of the cylinder 2 to achieve circumferential positioning, while the horizontal section is embedded in the moving groove 11 of the base plate 1 through a sliding block 312. At the same time, a reinforcing plate 311 is provided on the side of the positioning rod 31 facing away from the cylinder 2 to effectively enhance its bending and torsional stiffness, prevent bending deformation or failure when subjected to lateral forces or vibration loads, and ensure long-term reliability. A sliding block 312 is fixed at the lower end of the positioning rod 31, and the sliding block 312 forms a sliding fit with the moving groove 11 on the base plate 1, so that the positioning rod 31 can slide along the groove 11 during installation. The moving groove 11 slides radially in and automatically aligns with the positioning groove 21 on the outer periphery of the cylinder 2. This structure simplifies the assembly process, avoids forced hammering or adjustment, and ensures positioning accuracy while improving construction efficiency. The limiting ring 32 engages with the positioning rod 31 at its lower end and is fixed with bolts to the corresponding fastening screw holes 321 on the base plate 1, thereby constraining the positioning rod 31 in both radial and axial directions. In addition, the lower end of the limiting ring 32 is provided with a limiting block 323 that extends into the moving groove 11. This limiting block 323 directly abuts against the end of the sliding block 312 to prevent it from being damaged by vibration or external force during use. The force retraction or disengagement, this dual limiting mechanism, significantly improves the overall locking reliability of the fastening mechanism 3. Both the limiting ring 32 and the base plate 1 are provided with circumferentially distributed fastening screw holes 321, allowing for detachable connection of the limiting ring 32 via bolts. When disassembling the cylinder 2 or replacing components, simply loosening the bolts and removing the limiting ring 32 releases the positioning rod 31, eliminating the need for destructive operations and greatly improving maintenance convenience and component replaceability. The lower end of the base 41 has a circumferentially circumferentially opened assembly groove 411 that mates with the protruding post 221 on the inner extension plate 22. Simultaneously, a base post 412 is fixed at the center or circumferentially of the base 41. The column 412 is embedded in the groove 233 of the bearing plate 232. The fit between the mounting groove 411 and the protruding column 221 provides circumferential positioning to prevent the base 41 from rotating. The fit between the bottom column 412 and the groove 233 provides vertical support and center alignment. The bottom column 412 is embedded in the groove 233 of the bearing plate 232, which not only achieves mechanical limitation, but also ensures that the base 41 and the bearing plate 232 move synchronously when the spring strip 231 is compressed and deformed. This avoids uneven load or stress concentration caused by relative slippage, so that the vibration damping function of the buffer 23 can be effectively played, and at the same time, the positional stability of the base 41 under dynamic load is guaranteed.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: During the concrete foundation construction stage, multiple anchor rods 13 are pre-embedded vertically in the foundation, with their positions corresponding to the anchor holes at the lower end of the base plate 1. The base plate 1, preferably a circular plate, is hoisted above the foundation, allowing the anchor rods 13 at the lower end of the base plate 1 to pass through the pre-drilled holes in the base plate 1. The level and orientation of the base plate 1 are adjusted, and fine-tuning and initial fixing are performed using the fastening bolts 121 on the outer extension plate 12 of the outer periphery of the base plate 1. Finally, the anchor rods 13 are locked with nuts, and the fastening bolts 121 on the outer extension plate 12 are tightened to achieve a double reliable connection between the base plate 1 and the foundation. The cylinder 2 is then placed on the base plate. At the center of the cylinder 2, align the positioning groove 21 on its outer periphery with the moving groove 11 arranged circumferentially around the cylinder 2 on the base plate 1. Slide multiple L-shaped positioning rods 31 radially into the moving groove 11 from the outside until their vertical sections abut against the positioning groove 21 on the outer periphery of the cylinder 2, achieving circumferential positioning of the cylinder 2. The sliding block 312 at the lower end of the positioning rod 31 is fully embedded in the moving groove 11, ensuring smooth sliding and accurate positioning. Insert the limiting ring 32 from above, so that its lower end engages with the horizontal section of each positioning rod 31. Simultaneously, the limiting block 323 at the lower end of the limiting ring 32 falls into the corresponding moving groove 11 and abuts against the end of the sliding block 312, preventing... To prevent its retraction; the limiting ring 32 is detachably fixed to the base plate 1 by bolts through the corresponding fastening screw holes 321 on the base plate 1, thereby locking the position of the positioning rod 31 and completing the stable connection between the cylinder 2 and the base plate 1. In the internal cavity of the cylinder 2, the buffer 23 is pre-installed: the lower end of the spring strip 231 is fixed to the inner wall of the cylinder 2, and the upper end is connected to the bearing plate 232; the base 41 at the bottom of the mounting seat 4 is aligned with the inside of the cylinder 2, and the mounting groove 411 at the lower end of the base 41 is aligned and fitted with the protruding column 221 on the inner extension plate 22 to achieve circumferential limiting; the bottom column 412 at the lower end of the base 41 is inserted into the bearing plate. The groove 233 on 232 achieves center alignment and vertical support; the second connecting screw hole 401 at the lower end of the mounting base 4 is aligned with the first connecting screw hole 24 at the upper end of the cylinder 2, and the mounting base 4 and the cylinder 2 are fastened with bolts to complete the detachable connection between the mounting base 4 and the cylinder 2. The connecting rod 42 and the space frame bolt ball 43 at the upper end of the mounting base 4 have been pre-assembled in the factory; on site, the space frame members and the space frame bolt ball 43 are connected according to the design requirements to complete the assembly of the overall space frame structure. The whole process does not require welding. Each component is quickly and accurately assembled through sliding, fitting, bolt connection and other methods. The positioning is automatically aligned, the operation is simple and the construction period is greatly shortened.

[0042] When dismantling is required, loosen the connection between the space frame member and the space frame bolt ball 43, remove the connecting bolt between the lower end of the mounting base 4 and the cylinder 2, that is, loosen the bolts of the first connecting screw hole 24 and the second connecting screw hole 401, lift the mounting base 4 upwards so that its base 41 is disengaged from the groove 233 of the bearing plate 232 and the protrusion 221 of the inner extension plate 22; the mounting base 4 can be completely removed for easy replacement or maintenance. Loosen the fastening bolt 121 between the limiting ring 32 and the base plate 1, and remove the limiting ring 32 upwards. At this time, the limiting block 323 disengages from the moving groove 11, and the positioning rod 31... The axial constraint is lost; each positioning rod 31 is slid out radially along the moving groove 11, disengaging from the positioning groove 21 of the cylinder 2; the cylinder 2 is lifted vertically upwards, completing the disassembly of the cylinder 2. If only the upper structure is replaced, the bottom plate 1 can be retained on the foundation, and the anchor rod 13 and the bolt of the outer extension plate 12 provide continuous anchoring; if the entire structure needs to be disassembled, the fastening bolts 121 of the outer extension plate 12 and the nuts of the anchor rod 13 are loosened, and the entire structure is lifted away from the bottom plate 1. All connections are detachable mechanical connections, with no welding damage, and the parts can be reused; the disassembly sequence is clear, the operation is safe, and maintenance costs and construction risks are significantly reduced.
