Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, the present invention provides a splicing rotating ball joint, including a pre-embedded plate 1, a lower ball joint 2 fixed to the top of the pre-embedded plate 1, an upper ball joint 3 provided at the top of the lower ball joint 2, the lower ball joint 2 including a lower fan-shaped plate 18 distributed in a centrally symmetrical manner, the upper ball joint 3 including an upper fan-shaped plate 10 distributed in a centrally symmetrical manner, a tenon 16 is opened on the outer wall of the side of two adjacent upper fan-shaped plates 10 that are close to each other, a splicing tenon 17 is provided inside the tenon 16, a sealing layer 12 located at the top of the splicing tenon 17 is provided inside the tenon 16, and a friction pair 6 is provided between the lower fan-shaped plate 18 and the upper fan-shaped plate 10.

[0024] Specifically, in this embodiment, an embedded plate 1 is included, which is fixed to the structural foundation by casting. A lower ball joint 2 is fixed to the top of the embedded plate 1. The lower ball joint 2 is circular. An upper ball joint 3 is provided on the top of the lower ball joint 2. The upper ball joint 3 is also circular. The lower ball joint 2 includes lower fan-shaped plates 18 distributed in a centrally symmetrical manner. The upper ball joint 3 includes upper fan-shaped plates 10 distributed in a centrally symmetrical manner. A tenon 16 is opened on the outer wall of the side of two adjacent upper fan-shaped plates 10 that are close to each other. The tenon 16 is dovetail-shaped. A splicing tenon 17 is provided inside the tenon 16. The splicing tenon 17 is double dovetail-shaped. The two adjacent upper fan-shaped plates 10 are fixed by the splicing tenon 17. At the same time, the two adjacent lower fan-shaped plates 18 are also fixed by the splicing tenon 17. The tenon 16 is fixed, and a sealing layer 12 is provided inside the tenon 17 at the top. The sealing layer 12 is made of a high-polymer solidifiable sealant (such as resin), or it can be formed by filling with thin steel plate and spot welding. At the same time, the sealing layer 12 needs to be polished so that the arc surface of the sealing layer 12 matches the bottom of the upper ball joint 3. By setting the sealing layer 12 inside the tenon 16, the sharp corners of the tenon 16 are prevented from damaging the friction pair 6. A friction pair 6 is provided between the lower sector plate 18 and the upper sector plate 10. The friction pair 6 is used to make the rotation between the lower ball joint and the upper ball joint 3 stable. The splicing tenon 17 integrates the split structure into a whole structure, so that it still has the ability to resist horizontal forces.

[0025] This utility model provides a splicing swivel joint, in which multiple upper sector plates 10 are spliced ​​together to form an upper swivel joint 3, and multiple lower sector plates 18 are spliced ​​together to form a lower swivel joint 2. This reduces the weight of individual components, facilitates factory processing and semi-finished product transportation, and also facilitates on-site assembly. At the same time, the upper sector plates 10 and lower sector plates 18 can be made of hot-rolled steel plates to replace the original cast steel material of the integral structure, so that it has good mechanical properties, stable quality and low environmental pollution during manufacturing.

[0026] In another embodiment of this utility model, uniformly distributed steel rods 9 are fixed to the bottom outer wall of the embedded plate 1, which makes the embedded plate 1 more firmly fixed to the foundation. Positioning posts 11, which are centrally symmetrically distributed, are inserted into the top outer wall of the embedded plate 1. Positioning holes 19 are opened on the bottom outer wall of the lower fan-shaped plate 18, and the positioning posts 11 are inserted into the positioning holes 19. The positioning posts 11 fix the lower ball joint 2 to the embedded plate 1 and transmit the horizontal force of the upper structure. A bottom cover 13 is welded to the bottom outer wall of the embedded plate 1. The bottom cover 13 is located at the bottom of the positioning posts 11. The bottom cover 13 covers the holes at the bottom of the embedded plate 1, preventing concrete from entering the holes during grouting. The positioning post 11 provides a certain support effect; the outer wall of the positioning post 11 has an exhaust hole 14 to prevent the positioning post 11 from being squeezed out by compressed air when it is installed on the embedded plate 1; the top and bottom of the positioning post 11 are provided with a conical head 15, which facilitates the installation of the positioning post 11; the bottom outer wall of the upper ball joint 3 is provided with a convex surface 4, and the top outer wall of the lower ball joint 2 is provided with a concave surface 5. Through the convex surface and the concave surface 5, the force between the upper ball joint 3 and the lower ball joint 2 is evenly distributed; a central post 8 is fixed at the center of the top outer wall of the embedded plate 1, and a central hole 7 is opened at the center of both the upper ball joint 3 and the lower ball joint 2. The central post 8 is located inside the central hole 7, and the central hole 7 plays a centering role when the upper ball joint 3 rotates.

[0027] Working principle: During use, the embedded plate 1 is fixed to the structural foundation by pouring concrete. The positioning column 11 is installed on the embedded plate 1. The installation surface is cleaned. The segmented lower sector plates 18 are arranged in sequence, and the positioning column 11 is inserted into the positioning hole 19. Then, the splicing tenon 17 is inserted into the tenon 16 of the lower sector plate 18 in sequence, so that the segmented lower sector plates 18 are connected. The friction pair 6 is installed on the concave surface 5 of the lower ball joint 2 and lubricating silicone grease is applied. Then, the upper ball joint 3 is assembled in the same way.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
