AI Technical Summary
The existing space frame supports have difficulty making full contact between the cut surface and the connecting ball during construction, resulting in low on-site construction efficiency and poor overall stability of the space frame structure.
A large-span space frame support is designed, including an arc-shaped support plate, a support cylinder, a positioning rod, a limiting block, and an adjusting sleeve. The positioning rod is pushed into the connecting ball by the adjusting sleeve to ensure that the contact surface between the connecting ball and the arc-shaped support plate is subjected to uniform force in all directions, thereby enhancing the structural stability.
It improves the overall stability of the space frame structure, increases construction efficiency, ensures uniform stress distribution between the connecting spheres and the supporting plates, and enhances the stability of the structure.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0026] In related technologies, space frame structures, due to their varied construction and diverse shapes, are often used in large-span spatial structural systems. The supports for these structures typically consist of embedded plates, transition plates, support base plates, anchor bolts, and stiffening slabs. During construction, the stiffening slabs are usually cut into arc-shaped surfaces according to the size of the connecting spheres, resulting in low on-site construction efficiency and difficulty in achieving sufficient contact between the cut surfaces and the connecting spheres, leading to poor overall stability of the space frame structure.
[0027] This embodiment provides a large-span space frame support, which can improve the stability of the overall structure.
[0028] Please see Figures 1-2In this embodiment, a large-span space frame support includes an arc-shaped support plate 10, which is fixedly connected to a transition plate 12 for engaging a connecting ball 50. A support cylinder 20 is fixedly connected between the transition plate 12 and the arc-shaped support plate 10. A positioning rod 30 is inserted into the support cylinder 20. The positioning rod 30 can pass through the arc-shaped support plate 10 and be inserted into the interior of the connecting ball 50. A limiting block 31 is provided on the positioning rod 30, which extends out of the support cylinder 20 via a sliding groove 21. An adjusting sleeve 40 is screwed onto the outside of the support cylinder 20 and is engaged between the limiting blocks 31.
[0029] By adopting the technical solution of this embodiment, the positioning rod 30 can be pushed through the arc-shaped support plate 10 and inserted into the connecting ball 50 by rotating the adjusting sleeve 40. The force is evenly distributed in all directions on the contact surface between the connecting ball 50 and the arc-shaped support plate 10, which improves the overall stability of the space frame structure.
[0030] In this embodiment, the arc-shaped support plate 10 is constructed as a hemispherical shape. A stiffening plate 11 is welded between the transition plate 12 and the arc-shaped support plate 10, and the plane of the stiffening plate 11 is arranged along the diameter direction of the arc-shaped support plate 10. At the same time, the stiffening plate 11 is arranged perpendicularly to the transition plate 12. An embedded plate 13 is provided on the concrete column 14. The transition plate 12 is fixedly connected to the embedded plate 13 by anchor bolts. The connecting ball 50 is fitted into the interior of the arc-shaped support plate 10 with an overall shape that fits, and the outer wall of the connecting ball 50 is in contact with the inner wall of the arc-shaped support plate 10 to ensure that the force on the contact surface of the two is uniform in all directions.
[0031] In addition, the support cylinder 20 is welded between the transition plate 12 and the arc-shaped support plate 10, and the support cylinder 20 is symmetrically arranged on both sides of the stiffener 11. A sliding groove 21 is provided on the outer wall of the support cylinder 20. The extension direction of the sliding groove 21 is parallel to the axis of the support cylinder 20, and two sliding grooves 21 are evenly distributed along the circumference of the support cylinder 20.
[0032] Furthermore, the positioning rod 30 is slidably inserted into the support cylinder 20 along the axial direction. Limiting blocks 31 are welded on the outer wall of the positioning rod 30 and are arranged radially along the positioning rod 30. At the same time, the limiting blocks 31 are spaced apart along the axial direction of the positioning rod 30. The limiting blocks 31 extend to the outside of the support cylinder 20 through the slide groove 21 and are slidably engaged inside the slide groove 21. The adjusting sleeve 40 is screwed onto the outside of the support cylinder 20 and is rotatably engaged between two adjacent limiting blocks 31, so that when the adjusting sleeve 40 is screwed into the support cylinder 20, it can push the positioning rod 30 to slide inside the support cylinder 20.
[0033] It should be noted that a positioning hole 51 for inserting the positioning rod 30 is provided on the connecting ball 50, and the positioning hole 51 and the positioning rod 30 are arranged in a one-to-one correspondence.
[0034] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
