Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building, in particular to a large-span bolt-sphere net rack support and net rack structure in strong wind area. BACKGROUND

[0002] The net rack structure is generally used in large public and industrial buildings, such as stadiums, airports, exhibition halls and large industrial workshops, and is the most common structure form in large-span building structures in China. With the rapid development of economy and culture in China, the modeling of large-span buildings is becoming more and more novel and complex, and the diversification of their functions also makes the design load larger and larger, which puts higher requirements on structural design work.

[0003] The bolt-sphere net rack support is an important supporting component of the net rack structure, which not only bears the weight of the entire net rack structure itself, but also bears dynamic loads such as wind pressure, and the stress is complex. It generally includes a fixed bottom plate, a bolt-sphere and a plurality of reinforcing rib plates, the upper end of the reinforcing rib plate has a supporting curved surface matched with the spherical surface of the bolt-sphere, and the bolt-sphere is connected by welding. This structure has low strength because the bolt-sphere is only connected by the supporting curved surface at the upper end of the reinforcing rib plate, and it is difficult to position the bolt-sphere when welding with the reinforcing rib plate, which affects the welding quality and weld, and affects the carrying capacity of the entire net rack support. SUMMARY

[0004] In order to improve the carrying capacity of the bolt-sphere net rack support and make the bolt-sphere net rack stable in strong wind area, the present application provides a large-span bolt-sphere net rack support and net rack structure in strong wind area.

[0005] The large-span bolt-sphere net rack support in strong wind area provided by the present application adopts the following technical scheme:

[0006] A large-span bolt-sphere net rack support in strong wind area comprises a bolt-sphere, the surface of the bolt-sphere is provided with a first plane and a second plane, the first plane and the second plane are vertically arranged, and a fixing seat is arranged on each of the first plane and the second plane.

[0007] The fixing seat comprises a base and a connecting rod vertically fixed on the surface of the base, the connecting rod and the bolt-sphere are fixed together through connecting bolts, the outer side of the connecting rod is provided with a plurality of reinforcing rib plates arranged in a circumferential array with the connecting rod as the center, and the reinforcing rib plates abut against the bolt-sphere.

[0008] By adopting the technical scheme, when the bolt-sphere net rack support is fixed on the foundation, the two fixed seats arranged at an included angle can jointly decompose the force borne by the bolt-sphere net rack support and transmit the force to the connected foundation pile respectively, so that the horizontal force is not borne by the weld, the stability of the net rack support is greatly increased, and the bolt-sphere net rack support can be used in a strong wind area.

[0009] Optionally, the connecting rod is internally provided with a stepped hole, the stepped hole comprises a coaxial cavity and a communicating cavity, the diameter of the communicating cavity is smaller than the diameter of the cavity, the arrangement direction of the cavity and the communicating cavity is arranged from the end of the connecting rod connected with the base to the end of the connecting rod away from the base, the nut of the connecting bolt is located in the cavity, the screw rod of the connecting bolt passes through the communicating cavity and is connected with the bolt sphere, and the cavity is internally provided with an anti-loosening piece for limiting loosening of the connecting bolt.

[0010] By adopting the technical scheme, the connecting bolt is limited by the anti-loosening piece, so that the connecting bolt is not prone to loosening with the bolt sphere. Since the connecting bolt and the bolt sphere are connected together through threads, the bolt sphere and the fixed seat are prone to shaking under the blowing of strong wind, and the connecting bolt between the bolt sphere and the fixed seat is prone to rotating under the shaking, so that the connecting bolt and the bolt sphere are prone to loosening. The anti-loosening piece limits the axial direction of the connecting bolt, so that the connecting bolt is not prone to rotating due to shaking, and thus the connecting bolt and the bolt sphere are not prone to loosening, and the stability of the connection between the bolt sphere and the fixed seat is ensured.

[0011] Optionally, the anti-loosening piece is a straight rod structure, one end of the anti-loosening piece abuts against the base, and the other end of the anti-loosening piece abuts against the nut of the connecting bolt.

[0012] By adopting the technical scheme, the anti-loosening rod adopts a straight rod structure, which has the advantages of simple structure and convenient production, and the anti-loosening rod is not prone to bending deformation.

[0013] Optionally, the end of the connecting rod connected with the base is provided with a cover;

[0014] The anti-loosening piece comprises a telescopic rod located in the cavity and a control assembly for controlling length change of the telescopic rod, one end of the telescopic rod is connected with the cover, the other end of the telescopic rod abuts against the nut of the connecting bolt, and the telescopic rod applies a prestress to the connecting bolt.

[0015] By adopting the above technical solution, the telescopic rod applies a prestress to the connecting bolt, so that the connecting bolt can abut more tightly against the stepped surface formed between the cavity and the connecting cavity. At the same time, it can also make the thread of the connecting bolt and the bolt ball fit more tightly, so that the connecting bolt and the bolt ball are less likely to loosen.

[0016] Optionally, the telescopic rod includes a rotating threaded sleeve that is rotatably connected to the cover and a movable push rod that is threadedly connected to the rotating threaded sleeve;

[0017] The movable push rod includes a threaded section coaxially arranged and a smooth rod section with a polygonal cross-sectional shape. The threaded section is threadedly connected to the rotating threaded sleeve.

[0018] The cavity is provided with a limited rotating ring. The inner hole of the limited rotating ring is a polygonal hole that matches the cross-sectional shape of the optical rod segment. The optical rod segment passes through the inner hole of the limited rotating ring, and the optical rod segment and the limited rotating ring are slidably connected.

[0019] The control component includes an adjusting rod rotatably connected within the cavity. The adjusting rod is perpendicular to the rotating threaded sleeve. One end of the adjusting rod extends to the outside of the connecting rod. A transmission component is provided between the adjusting rod and the rotating threaded sleeve. Through the transmission component, when the adjusting rod rotates, the rotating threaded sleeve rotates synchronously.

[0020] By adopting the above technical solution, it is easy to adjust the length of the telescopic rod, and at the same time, the telescopic rod can be adjusted regularly to ensure that the telescopic rod can maintain the prestress applied to the connecting bolts.

[0021] Optionally, the included angle between the fixing seat located on the first plane and the fixing seat located on the second plane is adjustable.

[0022] By adopting the above technical solution, the included angle between the two fixed seats can be adjusted according to the actual situation of the installation position of the bolt ball grid support, making the bolt ball grid support easier to install.

[0023] Optionally, a rotating cavity is provided on the first plane, and a rotating seat is rotatably connected inside the rotating cavity. A fixed seat installed on the first plane is connected to the rotating seat. A locking mechanism is provided between the rotating seat and the bolt ball to restrict the rotation of the rotating seat.

[0024] By adopting the above technical solution, when it is necessary to adjust the angle of the rotating seat, the locking mechanism is released. After the locking mechanism is released, the rotating seat can be rotated to adjust the included angle between the two fixed seats. After the included angle between the two fixed seats is adjusted, the rotating seat is locked by the locking mechanism to restrict the rotation of the rotating seat and lock the included angle between the two fixed seats.

[0025] Optionally, the locking mechanism includes a housing fixed to the bolt ball, the housing having a hollow space inside, the rotating seat extending into the hollow space, and a first locking toothed disc and a second locking toothed disc disposed inside the hollow space. The toothed surfaces of the first and second locking toothed discs face each other. The first locking toothed disc is fixed to the rotating seat, and the second locking toothed disc is slidably connected within the hollow space. An elastic body is disposed between the first and second locking toothed discs, which can push the first and second locking toothed discs apart. A pusher is disposed on the side of the second locking toothed disc facing away from the first locking toothed disc, which can push the second locking toothed disc closer to the first locking toothed disc. When the second locking toothed disc approaches the first locking toothed disc, the first and second locking toothed discs can come into contact and mesh.

[0026] By adopting the above technical solution, when it is necessary to release the rotating seat, the pusher is first controlled to gradually move away from the second locking toothed disc. At this time, the elastic body located between the first and second locking toothed discs pushes the second locking toothed disc away from the first locking toothed disc. After the first and second locking toothed discs separate, the rotating seat can be rotated. When it is necessary to lock the rotating seat, the pusher is controlled to push the second locking toothed disc closer to the first locking toothed disc until the first and second locking toothed discs come into contact and mesh, thereby restricting the rotation of the rotating seat and locking the state of the rotating seat.

[0027] By employing the combination of the first locking gear and the second locking gear, the adjustable angle of the rotating seat can be made wider, thus adapting to more installation environments.

[0028] Optionally, the first locking toothed disc has a receiving cavity on the side facing the second locking toothed disc, and the elastomer is fixed in the receiving cavity.

[0029] By adopting the above technical solution, the elastomer is placed inside the receiving cavity, which can protect the elastomer and increase its service life.

[0030] The space frame provided in this application adopts the following technical solution:

[0031] A space frame structure includes a space frame body and large-span bolted ball space frame supports for strong wind areas located at both ends of the space frame body. The space frame body is connected to the bolted balls of the large-span bolted ball space frame supports for strong wind areas.

[0032] By adopting the above technical solutions, the space frame structure can be used in areas with strong winds, and the space frame can still maintain a relatively stable state under strong wind conditions.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By setting fixed seats on the first plane and the second plane respectively, when the bolt ball grid support is fixed to the foundation, the two fixed seats set at an angle can jointly decompose the force borne by the bolt ball grid support and transfer the force to the connected foundation piles respectively, avoiding the weld from bearing horizontal force, greatly increasing the stability of the grid support, and enabling the bolt ball grid support to be used in areas with strong winds;

[0035] 2. The telescopic rod applies a prestress to the connecting bolt, which allows the connecting bolt to abut more tightly against the stepped surface formed between the cavity and the connecting cavity. At the same time, it also allows the thread of the connecting bolt to fit more tightly with the bolt ball, thus making it less likely for the connecting bolt and the bolt ball to loosen.

[0036] 3. The included angle between the two fixed seats can be adjusted according to the actual installation position of the bolt ball grid support, making the bolt ball grid support easier to install. Attached Figure Description

[0049] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0050] Example 1

[0051] This application discloses a large-span bolted ball grid support for areas with strong winds.

[0052] Reference Figure 1 , Figure 2 The large-span bolted ball grid support in areas with strong winds includes a bolted ball 1 and two fixed seats 2 connected to the bolted ball 1, with the two fixed seats 2 arranged at an angle to each other.

[0053] The surface of the bolt ball 1 is provided with a first plane 11 and a second plane 12, which are perpendicular to each other. One of the two fixing seats 2 is installed on the first plane 11, and the other fixing seat 2 is installed on the second plane 12.

[0054] The mounting base 2 includes a base 21 and a connecting rod 22 vertically fixed to the surface of the base 21. The end of the connecting rod 22 away from the base 21 is connected to a bolt ball 1. A stepped hole is provided inside the connecting rod 22. The stepped hole includes a coaxially arranged cavity 221 and a communicating cavity 222, wherein the diameter of the communicating cavity 222 is smaller than the diameter of the cavity 221. The cavity 221 and the communicating cavity 222 are arranged from the end of the connecting rod 22 that is opposite to the base 21 towards the end of the connecting rod 22 that is away from the base 21.

[0055] A connecting bolt 23 is installed inside the stepped hole. The diameter of the nut of the connecting bolt 23 is larger than the diameter of the connecting cavity 222 but smaller than the diameter of the cavity 221. The nut of the connecting bolt 23 is located inside the cavity 221 and abuts against the stepped surface formed between the cavity 221 and the connecting cavity 222. The thread of the connecting bolt 23 passes through the connecting cavity 222 and extends to the outside of the connecting rod 22. The end of the thread of the connecting bolt 23 extending to the outside of the connecting rod 22 is threadedly connected to the bolt ball 1.

[0056] On the outer side of the connecting rod 22, multiple reinforcing ribs 24 are arranged in a circular array around the connecting rod 22. The reinforcing ribs 24 are welded and fixed to the base 21 and the connecting rod 22, respectively. One end of the reinforcing rib 24, away from the base 21, extends from the end of the connecting rod 22 away from the base 21 and abuts against the surface of the bolt ball 1. When the reinforcing rib 24 abuts against the bolt ball 1, it restrains the bolt ball 1, preventing it from wobbling.

[0057] An anti-loosening component 3 is also provided inside the cavity 221 of the connecting rod 22. In this embodiment, the anti-loosening component 3 adopts a straight rod structure. One end of the anti-loosening component 3 abuts against the base 21, and the other end of the anti-loosening component 3 abuts against the nut of the connecting bolt 23. Since the anti-loosening component 3 abuts against the connecting bolt 23, the nut of the connecting bolt 23 is restricted between the anti-loosening component 3 and the stepped surface formed between the cavity 221 and the connecting cavity 222. During use, due to the restriction of the connecting bolt 23 by the anti-loosening component 3, the connecting bolt 23 is not easy to rotate when there is shaking, thereby preventing loosening between the connecting bolt 23 and the bolt ball 1, ensuring the tightness of the connection between the connecting bolt 23 and the bolt ball 1.

[0058] The implementation principle of a large-span bolted ball grid support in a strong wind area according to an embodiment of this application is as follows: two fixed seats 2 arranged at an included angle can jointly decompose the force borne by the bolted ball grid support and transfer the force to the connected foundation piles respectively, avoiding the weld from bearing horizontal force and greatly increasing the stability of the grid support.

[0059] Example 2

[0060] This application discloses a large-span bolted ball grid support for areas with strong winds.

[0061] Reference Figure 3 , Figure 4 The difference between Embodiment 2 and Embodiment 1 lies in the structure of the anti-loosening component 3 located within the cavity 221. In this embodiment, the anti-loosening component 3 can apply prestress to the connecting bolt 23, further making the connecting bolt 23 less prone to loosening.

[0062] Reference Figure 4 , Figure 5 A cover 25 is provided at the end of the connecting rod 22 that is opposite to the base 21, and the cover 25 is fixedly connected to the connecting rod 22. The cover 25 is fixedly connected to the base 21.

[0063] The anti-loosening component 3 includes a telescopic rod 31 located inside the cavity 221. The telescopic rod 31 includes a coaxially arranged rotating threaded sleeve 311 and a movable push rod 312 threadedly connected to the rotating threaded sleeve 311. The rotating threaded sleeve 311 is rotatably connected to the cover 25. One end of the movable push rod 312 is threadedly connected to the rotating threaded sleeve 311, and the other end of the movable push rod 312 abuts against the nut of the connecting bolt 23.

[0064] The movable push rod 312 includes a threaded section 3121 and a smooth section 3122 with a polygonal cross-section, which are coaxially arranged. The threaded section 3121 and the smooth section 3122 are integrally formed. The threaded section 3121 is threadedly connected to the rotating threaded sleeve 311.

[0065] Reference Figure 5 , Figure 6 A finite rotating ring 26 is fixed inside the cavity 221. The inner hole of the finite rotating ring 26 is a polygonal hole adapted to the cross-sectional shape of the smooth rod segment 3122. For example, if the smooth rod segment 3122 is square, then the cross-sectional shape of the inner hole of the finite rotating ring 26 is also square. In this embodiment, the cross-sectional shape of the smooth rod segment 3122 is regular hexagonal, and the cross-sectional shape of the finite rotating ring 26 is also regular hexagonal. The smooth rod segment 3122 passes through the inner hole of the finite rotating ring 26. The smooth rod segment 3122 is slidably connected to the finite rotating ring 26.

[0066] Inside the cavity 221, a control component 32 is also provided to control the rotation of the rotating threaded sleeve 311. The control component 32 includes an adjusting rod 321 arranged perpendicular to the axial direction of the rotating threaded sleeve 311. A first bevel gear 322 and a second bevel gear 323 are meshed between the adjusting rod 321 and the rotating threaded sleeve 311. The first bevel gear 322 is coaxially arranged and fixed together with the rotating threaded sleeve 311. The second bevel gear 323 is coaxially arranged and fixed together with the adjusting rod 321. The adjusting rod 321 is rotatably connected inside the cavity 221. One end of the adjusting rod 321 passes through the connecting rod 22 and extends outward from the outside of the connecting rod 22. A cross groove is machined on the end face of the adjusting rod 321 extending outward from the connecting rod 22.

[0067] The implementation principle of a large-span bolted ball grid support in a strong wind area according to an embodiment of this application is as follows:

[0068] The control rod 321 rotates. As the control rod 321 rotates, the rotating threaded sleeve 311 rotates under the transmission action of the first bevel gear 322 and the second bevel gear 323. As the rotating threaded sleeve 311 rotates, the moving push rod 312 moves closer to the connecting bolt 23 and applies prestress to the connecting bolt 23, thereby pressing the nut of the connecting bolt 23 between the moving push rod 312 and the stepped surface formed between the cavity 221 and the connecting cavity 222.

[0069] Example 3

[0070] This application discloses a large-span bolted ball grid support for areas with strong winds.

[0071] Reference Figure 7 The difference between Embodiment 3 and Embodiment 1 or Embodiment 2 is that the included angle between the two fixed seats 2 is adjustable.

[0072] Reference Figure 8 A rotating cavity 111 is provided on the surface of the first plane 11, and a rotating seat 112 is provided inside the rotating cavity 111, extending out of the cavity opening. Extensions 1111 extending outward are provided on the left and right sides of the rotating cavity 111, respectively. The extensions 1111 are integrally formed or welded to the bolt ball 1, and the rotating seat 112 is rotatably connected between the two extensions 1111. The rotating seat 112 is positioned vertically. A fixed seat 2 connected to the first plane 11 is connected to the rotating seat 112.

[0073] The rotating seat 112 includes a main body 1121 located between two extensions 1111 and a rotating shaft 1122. The rotating shaft 1122 is integrally formed or welded to the main body 1121, and the rotating shaft 1122 is rotatably connected to the two extensions 1111.

[0074] One end of the rotating shaft 1122 passes through the connected extension 1111, extending to the outside of the extension 1111. A locking mechanism 4 is provided on the outside of the extension 1111 through which the rotating shaft 1122 passes, and the locking mechanism 4 is used to restrict the rotation of the rotating shaft 1122.

[0075] Reference Figure 9 , Figure 10 The locking mechanism 4 includes a housing 41 fixed to the outside of the extension 1111. A hollow space 411 is provided inside the housing 41, and a rotating shaft 1122 extends into the hollow space 411. A first locking toothed disc 42 and a second locking toothed disc 43 are disposed inside the hollow space 411, with their toothed surfaces facing each other. The first locking toothed disc 42 is fixed to the rotating shaft 1122, and the second locking toothed disc 43 is slidably connected within the hollow space 411. The second locking toothed disc 43 can move closer to or further away from the first locking toothed disc 42. When the second locking toothed disc 43 moves closer to the first locking toothed disc 42, the toothed surfaces of the first and second locking toothed discs 42 and 43 mesh. When the toothed surfaces of the first and second locking toothed discs 42 and 43 mesh, the rotation of the rotating shaft 1122 is restricted.

[0076] Multiple guide rods 44 are arranged inside the hollow space 411. The axial direction of the guide rods 44 is parallel to the axial direction of the rotating shaft 1122, and the guide rods 44 are fixedly connected to the housing 41. All guide rods 44 are slidably connected to the second locking gear 43. The guide rods 44 can limit the movement direction of the second locking gear 43 and simultaneously limit the rotation of the second locking gear 43.

[0077] A receiving cavity 421 is provided on the surface of the first locking toothed disc 42 facing the second locking toothed disc 43. A compression spring 45 is disposed inside the receiving cavity 421. One end of the compression spring 45 is fixedly connected to the first locking toothed disc 42, and the other end of the compression spring 45 freely abuts against the second locking toothed disc 43. When the toothed surfaces of the first locking toothed disc 42 and the second locking toothed disc 43 are in contact and meshing, the compression spring 45 is in a compressed state.

[0078] An adjusting bolt 46 is provided on the second locking gear 43 facing away from the first locking gear 42. The adjusting bolt 46 is threadedly connected to the housing 41. One end of the adjusting bolt 46 extends into the interior of the hollow space 411, and the other end is located on the outside of the housing 41. The end of the adjusting bolt 46 extending into the hollow space 411 abuts against the second locking gear 43.

[0079] The implementation principle of a large-span bolted ball grid support in a strong wind area according to an embodiment of this application is as follows:

[0080] When it is necessary to adjust the included angle between the two fixed seats 2, first loosen the adjusting bolt 46 so that the adjusting bolt 46 moves outward from the housing 41. As the adjusting bolt 46 is loosened, the compression spring 45 pushes the second locking toothed disc 43 away from the first locking toothed disc 42 until the second locking toothed disc 43 is completely separated from the first locking toothed disc 42. At this time, the rotating seat 112 can be rotated to adjust the included angle between the two fixed seats 2.

[0081] After the included angle between the two fixed seats 2 is adjusted, rotate the adjusting bolt 46 to move the adjusting bolt 46 toward the interior of the hollow space 411. As the adjusting bolt 46 moves, it pushes the second locking toothed disc 43 closer to the first locking toothed disc 42, and makes the first locking toothed disc 42 and the second locking toothed disc 43 mesh, thereby locking the rotating shaft 1122 and restricting the rotation of the rotating shaft 1122. At this time, the included angle between the two fixed seats 2 is locked.

[0082] This application also discloses a space frame, as shown in the reference. Figure 11 The space frame includes a space frame body 5 and large-span bolted ball space frame supports for strong wind areas disclosed in this application, which are located at both ends of the space frame body 5. The large-span bolted ball space frame supports for strong wind areas can be any of the large-span bolted ball space frame supports for strong wind areas disclosed in Embodiment 1, Embodiment 2 or Embodiment 3 of this application. The space frame body 5 and the bolted balls 1 of the large-span bolted ball space frame supports for strong wind areas are fixed together.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
