[0024] The utility model is further described below in conjunction with embodiments.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 5The fixing assembly 6 includes a fixing block 61 threadedly connected to the outer surface of the stud body 4, a first connecting block 62 and a second connecting block 63 fixedly connected to the outer surface of the fixing block 61, a first auxiliary bolt 64 movably arranged between the first connecting block 62 and the first limiting block 8, and a second auxiliary bolt 65 movably arranged between the second connecting block 63 and the stud head 5. The stud body 4 serves as a connecting piece between the base plate 2 and the connecting pier 1, providing an adjustable connection method, enhancing the shear and tensile properties of the overall structure, the first limiting block 8 is threadedly connected to the stud body 4, which is convenient for effectively limiting the displacement of the stud body 4 in the vertical direction, preventing the upper structure from being offset or falling off due to external force, and increasing the safety factor of the structure. Under the action of the first auxiliary bolt 64 and the second auxiliary bolt 65, the first limiting block 8 and the stud head 5 are fixed through the fixing block 61, ensuring a firm connection between the first limiting block 8 and the stud head 5, and effectively preventing the stud body 4 from being displaced or falling off under the action of external force.

[0027] A first groove 81 is provided on the outer surface of the first limiting block 8, and the first connecting block 62 is engaged with the first groove 81. A first threaded hole 811 is provided on the inner wall of the first groove 81, and the first threaded hole 811 is threadedly connected with the first auxiliary bolt 64. The engagement connection between the first connecting block 62 and the first groove 81 facilitates the precise installation position of the fixing block 61. Removing the first auxiliary bolt 64 facilitates the separation of the fixing block 61 from the first limiting block 8.

[0028] A second groove 611 is formed on the upper surface of the fixing block 61, and a rubber gasket 9 is engaged and connected inside the second groove 611. The elasticity of the rubber gasket 9 provides a certain pre-tightening force, which helps the stud head 5 to remain stable when subjected to dynamic loads and prevents the stud body 4 from loosening due to slight displacements, thereby increasing the stability of the connection.

[0029] A limiting groove is provided on the lower surface of the stud head 5, and the limiting groove is engaged with the rubber gasket 9. A second threaded hole 51 is provided on the outer surface of the stud head 5, and the second threaded hole 51 is threadedly connected with the second auxiliary bolt 65. The cooperation between the limiting groove and the rubber gasket 9 plays a limiting role, preventing the stud head 5 from moving in the vertical direction, ensuring the precise centering and stability of the entire column base structure. Removing the second auxiliary bolt 65 makes it easy to separate the fixing block 61 from the stud head 5.

[0030] A second limiting block 11 is fixedly connected to the top of the connecting pier 1 , and the second limiting block 11 is threadedly connected to the stud body 4 . The second limiting block 11 plays a positioning role, which facilitates better installation of the stud body 4 .

[0031] The outer surface of the first limit block 8 is fixedly connected with a positioning block 7, and a locking bolt 71 is threadedly connected between the positioning block 7 and the base plate 2. The threaded connection between the positioning block 7 and the base plate 2 is convenient for disassembly, regular inspection and tightening, and ensures that the structure is in good condition for a long time.

[0032] A slot 21 is provided on the upper surface of the base plate 2, and a protective cover 10 is inserted into the slot 21. The stud body 4 and the stud head 5 are both arranged inside the protective cover 10. The protective cover 10 covers the stud body 4 and the stud head 5, which is convenient for effectively preventing external factors such as rain, dust, corrosive substances, etc. from directly contacting the stud body 4 and the stud head 5, reducing the risk of rust and wear.

[0033] When in use, the stud body 4 serves as a connecting piece between the base plate 2 and the connecting pier 1, providing an adjustable connection method, enhancing the shear and tensile properties of the overall structure, the first threaded hole 811 is threadedly connected to the first auxiliary bolt 64, and the second threaded hole 51 is threadedly connected to the second auxiliary bolt 65. At this time, the first limit block 8 and the stud head 5 are fixed by the fixing block 61, ensuring a firm connection between the first limit block 8 and the stud head 5, and effectively preventing the stud body 4 from being displaced or falling off under the action of external force. The elasticity of the rubber gasket 9 provides a certain pre-tightening force, which helps the stud head 5 to remain stable when subjected to dynamic loads, and prevents the stud body 4 from loosening due to slight displacement, thereby increasing the stability of the connection.
