Description

Technical Field

[0001] This utility model relates to the field of space frame connection technology, specifically to a steel structure space frame reinforcement device. Background Technology

[0002] Bolted ball joints consist of components such as a ball, high-strength bolts, sleeves, fastening screws, and conical heads or end plates, used to connect steel pipe members in space structures such as grid frames and double-layer grid shells. The diameter of the selected high-strength bolts should be determined by the internal forces of the tension members. For compression members, the bolt diameter can be calculated based on the absolute value of the internal force design, then reduced by 1-3 grades according to the bolt diameter series. Based on the stress characteristics of bolted ball joint connections, the axial pressure of compression members is mainly transmitted through the bearing pressure of the sleeve end face, with the bolt primarily serving a connecting function; tension members mainly transmit tensile force through the bolts, making the bolts the primary load-bearing components. Therefore, the connection quality of the high-strength bolts has a significant impact on the load-bearing capacity of the grid frame members.

[0003] Existing measures to strengthen insufficient space frame strength are often limited to directly replacing members or replacing the entire space frame, resulting in high maintenance costs. Replacing members or replacing the entire space frame requires full-span support and unloading of existing loads, which makes construction difficult and time-consuming. Utility Model Content

[0024] The present invention will now be described in further detail in conjunction with the full text.

[0025] Combined with appendix Figure 1 and Figure 2 A steel structure space frame reinforcement device includes a bolt ball 1 and a rod 4. The bolt ball 1 has a mounting hole 2 on its surface, and a high-strength screw rod 3 is installed inside the mounting hole 2, which is a frustum structure. One side of the rod 4 is threadedly connected to the high-strength screw rod 3, which enters the mounting hole 2. A limiting device 5 for reinforcement is installed between the bolt ball 1 and the rod 4. An auxiliary device 6 for limiting is installed between the limiting device 5 and the rod 4. Specifically, the end of the rod 4 near the high-strength screw rod 3 has a conical structure that mates with the mounting hole 2, and a threaded hole is opened at the end of the rod 4 near the high-strength screw rod 3. During this process, the threaded hole of the rod 4 and the high-strength screw rod 3 are rotatably connected and enter the rod 4. The outer side of the rod 4 fits against the inner wall of the mounting hole 2, increasing the contact area, and is further limited by the limiting device 5, thus providing reinforcement.

[0026] In specific implementation of this utility model, such as Figure 1 and Figure 2As shown, a reinforcing limiting device 5 is installed between the bolt ball 1 and the rod 4. The limiting device 5 includes multiple sets of limiting rods 501. A first groove 502 is formed on the inner wall of the mounting hole 2 to accommodate the limiting rod 501. A second groove 503 is formed on the outer side of the end of the rod 4 near the mounting hole 2 to accommodate the limiting rod 501. The limiting rod 501 can be inserted into the first groove 502 and the second groove 503 to complete the limiting. The limiting rod 501 installed in the first groove 502 and the second groove 503 provides axial limiting for the bolt ball 1 and the rod 4.

[0027] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown. A limiting groove 504 is opened on the outer side of the bolt ball 1, and the limiting groove 504 is connected to the first groove 502. A high-strength screw rod 505 is installed in the limiting groove 504. A connecting block 506 is installed at one end of the limiting rod 501. A waist hole 507 is opened on the connecting block 506 to allow the high-strength screw rod 505 to pass through. A nut 508 for fixing is installed on the outer side of the high-strength screw rod 505. Specifically, the limiting rod 501 and the connecting block 506 are an integrated L-shaped structure. The connecting block 506 enters the limiting groove 504, the high-strength screw rod 505 passes through the waist hole 507, and the nut 508 rotates on the outer side of the high-strength screw rod 505 to approach the connecting block 506, which serves to limit and push the limiting rod 501 into the first groove 502 and the second groove 503.

[0028] In specific implementation of this utility model, such as Figure 2 As shown. An auxiliary device 6 for limiting is installed between the limiting device 5 and the rod 4. The auxiliary device 6 includes two elastic retaining rings 601. An installation groove 602 for using the elastic retaining rings 601 is opened on the outer side of the rod 4. A through hole 603 for using the elastic retaining rings 601 is opened on the limiting rod 501. The elastic retaining rings 601 are semi-circular retaining spring structures. The elastic retaining rings 601 are elastic structures that can be manually straightened. They will return to their original shape due to the elastic force when the external force is lost. One end of the elastic retaining rings 601 can be in the installation groove 602 and then pass through the through hole 603 to complete the limiting. Specifically, the two elastic retaining rings 601 can also be made of elastic steel wire. The steel wire is directly installed in the installation groove 602 from one end and then passes through the through hole 603 of the limiting rod 501. The two ends of the steel wire can be twisted together with pliers.

[0029] Example 1:

[0030] like Figure 1As shown, the threaded hole of rod 4 is rotatably connected to and enters the high-strength screw 3. The outer side of rod 4 fits against the inner wall of mounting hole 2. Rod 4 is installed in mounting hole 2, and groove 1 502 and groove 2 503 are connected. Limiting rod 501 is installed in groove 1 502 and groove 2 503, which axially limits the bolt ball 1 and rod 4. Nut 508 rotates to approach connecting block 506 on the outside of high-strength screw 2 505, which limits the movement and pushes limiting rod 501 into groove 1 502 and groove 2 503. One end of elastic retaining ring 601 can pass through mounting groove 1 602 and then through waist hole 603 to complete the limiting, improve the bearing capacity of the space frame bolt ball node, and play a strengthening role.

[0031] Example 2:

[0032] like Figure 3 As shown, compared to Embodiment 1, Embodiment 2 has multiple sets of rods 4, which can be installed on the surface of the bolt ball 1 to realize the connection structure of multiple sets of rods 4.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
