[0002] In the field of modern building structures, bolted ball space frames are widely used in the roofs and load-bearing systems of large-span buildings such as stadiums, airport terminals, and large factories due to their light weight, large span, and excellent seismic performance. As the core connecting component of a bolted ball space frame, the tie rod node plays a crucial role in transferring loads and maintaining the overall stability of the structure; its connection reliability directly affects the safety performance and service life of the entire space frame structure.
[0003] A search revealed that Chinese Patent Publication No. CN 219175945 U discloses a reinforcement device for bolted ball space frame tie rods and nodes, relating to the field of bolted ball space frame technology. This utility model includes a bolted ball body, a first tie rod with a first open fastening ring fitted around its outer ring, four first welding blocks each welded with a first support rod, four second tie rods with second open fastening rings fitted around their outer rings, two second welding blocks near the first support rods on the second open fastening rings each welded with a second support rod, four third tie rods with third open fastening rings fitted around their outer rings, two mutually distant third welding blocks on the third open fastening rings each welded with a fourth support rod, and a third support rod welded to the middle of each of the four second support rods. This utility model utilizes the first, second, third, and fourth support rods to reinforce and support the tie rods of the space frame and the nodes between the tie rods and the bolted ball, thereby improving the load-bearing capacity of the bolted ball space frame and eliminating the safety hazards of instability in the bolted ball space frame.
[0004] The bolted ball joint in the aforementioned patent still has certain shortcomings. Due to the long-term use of existing bolted ball joints, the connection points are often affected by humid or corrosive media, which leads to corrosion at the joint points. This reduces the interlocking force between the bolt and the ball joint, further increasing the risk of loosening at the connection points and posing a significant safety hazard.

[0023] Please see Figure 1-4 ,
[0024] Example 1: A reinforcement device for the tie rod node of a bolted ball grid frame includes a bolted ball 1, with insertion screw holes 2 evenly opened around the circumference of the bolted ball 1, and tie rod node reinforcement components 3 provided on the outer side of each insertion screw hole 2.
[0025] The tie rod node reinforcement component 3 includes a space frame connecting tie rod 301 disposed on the side of the insertion screw hole 2. The end of the space frame connecting tie rod 301 is provided with a reinforcing bolt 302. The reinforcing bolt 302 is connected to the space frame connecting tie rod 301 through a rotating connecting block 303. The reinforcing bolt 302 is inserted into the insertion screw hole 2. The end of the space frame connecting tie rod 301 is provided with an installation slot 304. A connecting plate 305 is inserted into the installation slot 304. Two side slots 306 are symmetrically provided at both ends of the connecting plate 305. A central through hole 307 is provided in the middle of the connecting plate 305.
[0026] A reinforcing connecting rod 308 is provided between every two space frame connecting rods 301. A connecting plug 309 is fixed to the end of each reinforcing connecting rod 308. A connecting socket 310 is provided in the middle of the connecting plug 309. The connecting plug 309 is inserted into the side slot 306. A fixing screw 311 is inserted into the connecting socket 310. The end of the fixing screw 311 passes through the middle through hole 307. Two fixing nuts 312 are symmetrically fitted at both ends of the fixing screw 311. A fastening screw hole 313 is provided at the top of the space frame connecting rod 301. A fastening bolt 314 is inserted into the fastening screw hole 313.
[0027] Example 2: The difference between this example and Example 1 is that the inner diameter of the side slot 306 is larger than the diameter of the connector 309.
[0028] This allows the side slot 306 to limit the position of the connector 309.
[0029] Example 3: The difference between this example and Example 1 is that the reinforcing connecting rod 308 and the connecting plug 309 are connected at an angle.
[0030] This makes it easier for the connector plug 309, which is connected to the end of the reinforcing connecting rod 308, to be inserted into the side slot 306 for connection.
[0031] Example 4: The difference between this example and Example 1 is that a rotating block is provided at the top of the fastening bolt 314.
[0032] This makes it easier for users to rotate the fastening bolt 314.
[0033] In this embodiment, due to the long-term use of existing bolted ball joints, the connection nodes are often affected by moisture or corrosive media, which leads to corrosion at the connection nodes. This reduces the interlocking force between the bolts and the ball joints, further increasing the risk of loosening at the connection nodes and posing a significant safety hazard.
[0034] In summary, in specific implementation, in order to make the connection between the bolt ball 1 and the space frame connecting rod 301 in the tie rod node reinforcement assembly 3 more stable, tie rod node reinforcement assemblies 3 are evenly arranged around the bolt ball 1. The end of the space frame connecting rod 301 in the tie rod node reinforcement assembly 3 is connected to the bolt ball 1 by a reinforcing bolt 302 inserted into the insertion screw hole 2. The reinforcing bolt 302 and the space frame connecting rod 301 are rotatably connected by a rotating connecting block 303, so that the reinforcing bolt 302 rotates into the insertion screw hole 2 without causing the space frame connecting rod 301 to rotate. The end of the space frame connecting rod 301 is provided with an installation slot 304.
[0035] The mounting slot 304 contains a connecting plate 305. The top of the space frame connecting rod 301 has a fastening screw hole 313, and a fastening bolt 314 is inserted into the fastening screw hole 313. The fastening bolt 314 rotates in the fastening screw hole 313 and can abut against the top side of the connecting plate 305, fixing it in the mounting slot 304. The two ends of the connecting plate 305 have symmetrical side slots 306. The user can insert the connecting plug 309 connected to the end of the reinforcing connecting rod 308 into the side slots 306 respectively, and then insert a fixing screw 311 into the connecting hole 310 in the middle of the connecting plug 309, so that the end of the fixing screw 311 passes through the middle through hole 307 and the connecting hole 310 in sequence.
[0036] By fitting fixing nuts 312 onto both ends of the fixing screw 311, the connection between each space frame connecting rod 301 is further strengthened, thereby making the connection between the bolt ball 1 and the rod node reinforcement component 3 stable. Even if the reinforcing bolt 302 corrodes at the insertion point of the bolt hole 2, the connection between the space frame connecting rod 301 and the bolt ball 1 will not be too loose, thus further strengthening its interlocking force and ensuring safe use by the user.
