Description
Technical Field
[0001] This utility model belongs to the field of space frame structure technology, specifically relating to a bolt ball space frame ground assembly frame. Background Technology
[0002] With the rapid development of modern construction technology, large-span, complex space frame structures have been widely used in public buildings and industrial facilities such as stadiums, exhibition halls, airport terminals, and large industrial plants due to their unique advantages, such as good spatial load-bearing performance, lightweight structural self-weight, flexible design capabilities, and high economic benefits. Bolted ball space frames, as an important form of space frame structure, are particularly favored by the engineering community for their simple node connections, fast installation speed, and ease of disassembly and reassembly.
[0003] In the construction of bolted ball grid structures, the ground assembly stage is a crucial step that directly affects the quality and efficiency of subsequent hoisting and installation.
[0004] Existing technologies use ground-based assembly jigs to support bolted ball space frames. For example, Chinese patent publication CN117780154A, entitled "A Ground-Based Assembly Jig for Steel Space Frames and its Method of Use," is used to support the assembly of steel space frames. It employs a fixing device to support the bolted balls. The existing fixing device is a fixed ring, with the bolted balls held in place and limited in position. However, in existing technologies, there is a risk of the bolted balls falling out during the assembly of the bolted ball space frame. Utility Model Content
[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a ground assembly frame for bolt ball netting, so that the bolt ball is fixed on the support plate and the bolt ball is prevented from falling off the support plate.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A ground assembly frame for bolted ball space frames includes a base plate and support units. The base plate is fixed to a concrete floor, and several support units are installed on the base plate. The key feature is that each support unit includes a fixed base, support members, and a support plate. The support members are located between the fixed base and the support plate. The fixed base is fixed to the base plate, and the support plate supports the bolted balls. The support plate has at least three support rods that clamp the bolted balls, securing them to the support plate and preventing them from falling off. This also ensures precise positioning of the bolted balls within the designated positions on the support plate, improving the assembly accuracy of the bolted ball space frame.
[0008] Furthermore, the support plate is circular and has a through hole. The axis of the through hole is set along the diameter of the support plate. The support rod passes through the through hole and moves along the axis of the through hole. The support rod has a limiting structure. After adjustment, the support rod is limited on the support plate by the limiting structure, so that the support rod can clamp and fix bolt balls of different diameters. It has a wide range of applications and avoids the bolt balls from moving due to gaps between the support rod and the bolt balls, thus improving the assembly accuracy of the bolt ball space frame.
[0009] Furthermore, the limiting structure includes a limiting plate one, a limiting plate two, and a fixing nut. The limiting plate one is welded to the bottom of the support rod and is attached to the bottom surface of the support plate. The limiting plate two has a round hole through which the support rod passes. The fixing nut is threaded onto the support rod and simultaneously presses the limiting plate two, so that the limiting plate two is attached to the top surface of the support plate. This facilitates the quick installation of the support rod in the through hole of the support plate and allows for quick adjustment of the position of the support rod in the through hole.
[0010] Furthermore, the top of the support rod is provided with an end, which is hemispherical, to ensure that the fixing nut and the limiting piece are smoothly installed on the support rod.
[0011] Furthermore, the support component includes sleeve one, a threaded rod, and sleeve two. Sleeve one is welded and fixed to the fixed base, and sleeve two is welded and fixed to the support plate. The threaded rod extends into the first hole of sleeve one and the second hole of sleeve two. The threaded rod is threadedly connected to two adjusting nuts distributed vertically. The lower adjusting nut is supported on sleeve one, and sleeve two is supported on the upper adjusting nut. By adjusting the position of the lower adjusting nut on the threaded rod, the length of the threaded rod extending into sleeve one can be changed. At the same time, by adjusting the position of the upper adjusting nut on the threaded rod, the length of the threaded rod extending into sleeve two can be changed, thereby adjusting the height of the support component. This allows for adjustment of the jig height according to the height of the bolt ball grid structure during installation, ensuring that the assembly accuracy of the bolt ball grid structure is controlled.
[0012] Furthermore, the support plate is provided with mounting holes, and the second sleeve is welded into the mounting holes. A backing plate is welded into the second sleeve hole. The backing plate can increase the strength of the second sleeve. At the same time, the bolt ball is supported on the backing plate. The surface of the backing plate is flat, which reduces the risk of scratching the coating on the surface of the bolt ball.
[0013] Furthermore, stiffening ribs are welded between the sleeve and the fixed base to increase the connection strength between the sleeve and the fixed base.
[0014] Furthermore, the fixed base is fixed to the base plate by connecting bolts, which facilitates the installation or disassembly of the entire support unit on the base plate, enables the support unit to be recycled and reused, and ensures the stability of the jig.
[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:
[0016] When assembling a bolt ball grid on the ground, the bolt balls are placed on a support plate. Since the bolt balls are spherical, they can roll. Therefore, this invention provides at least three support rods on the support plate to clamp the bolt balls, thus fixing them to the support plate and preventing them from falling off. It also allows for precise positioning of the bolt balls at the designated positions on the support plate, improving the assembly accuracy of the bolt ball grid. Attached Figure Description

Detailed Implementation
[0028] like Figures 1 to 9 As shown, this utility model provides a bolted ball grid ground assembly frame, which includes a base plate 1 and a support unit 3. The base plate 1 is fixed on a flat concrete floor 2.
[0029] Based on the span of the bolt ball grid, the lines are laid out on site, and then multiple support units 3 are installed on the base plate 1 to support the bolt ball grid.
[0030] like Figure 1 and Figure 2 As shown, the support unit 3 of this utility model includes a fixed base 5, a support member 6 and a circular support plate 7. The support member 6 is located between the fixed base 5 and the support plate 7. The fixed base 5 is fixed to the base plate 1 by connecting bolts 24, which facilitates the installation or disassembly of the entire support unit 3 on the base plate 1, enables the support unit 3 to be recycled and reused, and ensures the stability of the frame.
[0031] The support plate 7 supports the bolt balls 4. The support plate 7 has at least three through holes 12, and each support plate 7 of this invention has four through holes 12. The axis of the through holes 12 coincides with the diameter of the support plate 7. The top of the support rod 8 has an end 23, which is hemispherical. A single support rod 8 passes through each through hole 12 and moves along the axis of the through hole 12. The support rod 8 has a limiting structure. After adjustment, the support rod 8 is limited on the support plate 7 by the limiting structure, so that the support rod 8 can clamp and fix bolt balls 4 of different diameters. At this time, the support rod 8 does not block the web members 25 of the bolt ball grid, which has a wide range of applications. At the same time, it avoids the bolt balls 4 from moving due to gaps between the support rod 8 and the bolt balls 4, so that the bolt balls 4 are fixed on the support plate 7 and will not fall off the support plate 7. At this point, the bolt ball 4 is precisely positioned at the set position of the support plate 7, and then the bolt ball 4 and the web rod 25 are assembled into a bolt ball net frame, which has high assembly accuracy.
[0032] The present invention specifically designs a limiting structure: the limiting structure includes a limiting plate 9, a limiting plate 10, and a fixing nut 11. The limiting plate 9 is welded to the bottom of the support rod 8 and is attached to the bottom surface of the support plate 7. The limiting plate 10 has a round hole 21 through which the support rod 8 passes. The fixing nut 11 is threaded onto the support rod 8 and simultaneously presses the limiting plate 10, so that the limiting plate 10 is attached to the top surface of the support plate 7. This facilitates the quick installation of the support rod 8 in the through hole 12 of the support plate 7 and allows for quick adjustment of the position of the support rod 8 in the through hole 12.
[0033] The support component 6 includes a first sleeve 13, a threaded rod 14, and a second sleeve 15. The first sleeve 13 is welded to the fixed base 5, and a stiffening rib 17 is welded between the first sleeve 13 and the fixed base 5 to increase the connection strength between them. The support plate 7 has a mounting hole 22, and the second sleeve 15 is welded into the mounting hole 22. A pad 20 is welded into the second hole 19 of the second sleeve 15, extending out of the top surface of the support plate 7. The pad 20 increases the strength of the second sleeve 15, and the bolt ball 4 is supported on the pad 20. The surface of the pad 20 is flat, reducing the risk of scratching the coating on the surface of the bolt ball 4. The threaded rod 14 extends into the first hole 18 of the first sleeve 13 and the second hole 19 of the second sleeve 15. The threaded rod 14 is threadedly connected to two adjusting nuts 16, which are distributed vertically. The lower adjusting nut 16 is supported on the first sleeve 13, and the second sleeve 15 is supported on the upper adjusting nut 16. By adjusting the position of the lower adjusting nut 16 on the threaded rod 14, the length of the threaded rod 14 extending into the sleeve 13 can be changed. At the same time, by adjusting the position of the upper adjusting nut 16 on the threaded rod 14, the length of the threaded rod 14 extending into the sleeve 15 can be changed, thereby adjusting the height of the support 6. The height of the jig can be adjusted according to the height of the bolt ball grid structure during installation, ensuring that the assembly accuracy of the bolt ball grid is controlled.
[0034] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
