In other embodiments, the connection method between the spherical steel support and other structures can also be other methods, and correspondingly, the materials used can also be other materials. Those skilled in the art can configure this according to actual conditions, and the present invention is not limited to this.

[0075] It should be noted that the spherical steel support provided in the embodiment of the present invention has a graded release sliding function, a tensile function and a shearing function; wherein the graded release sliding function is achieved by controlling the number of third limit members 80 filled into the first sliding cavity to limit the displacement of the steel support body 10 in the first direction 40, and controlling the number of fourth limit members 90 filled into the second sliding cavity to limit the displacement of the steel support body 10 in the second direction 50; the tensile function is achieved by the first connecting member 101 and the teeth on the first support plate 20 are engaged with each other, and the second connecting member 102 and the teeth on the second support plate 60 are engaged with each other. The teeth are engaged with each other, the first engaging part 1041 and the second engaging part 1024 are abutted against each other, the third engaging part 1052 and the fourth engaging part 1025 are abutted against each other, and the fifth engaging part 1062 is abutted against the bottom surface of the first connecting member 101. The anti-shear function is realized by the mutual engagement of the teeth on the first connecting member 101 and the first support plate 20, the mutual engagement of the teeth on the second connecting member 102 and the second support plate 60, the relative movement between the first connecting member 101 and the first support plate 20, and the mutual movement between the second connecting member 102 and the bracket of the second support plate 60. The graded release sliding function enables the steel support body 10 to release stress and other harmful secondary internal forces in the first direction 40 and the second direction 50; the tensile and shearing functions make the spherical steel support safer and more reliable in use, and increase the practical performance of the spherical steel support.

[0076] In summary, in the spherical steel bearing provided in the embodiment of the present invention, the spherical steel bearing includes: a steel bearing body, a first bearing plate and two first limit members; the extension direction along the first bearing plate is the first direction, and the direction along the same plane and intersecting the first direction at an angle is the second direction; the two first limit members are arranged at intervals on the bottom surface of the first bearing plate along the first direction; the steel bearing body is movably arranged between the two first limit members along the first direction.

[0077] With such configuration, the steel support body can move between the two first limit members along the first direction during the installation process, and can move between the two second limit members along the second direction as needed, thereby releasing the stress concentration caused by locking the steel support body, the harmful internal forces of the main structure, and other harmful secondary internal forces, thereby improving the stress state of the main structure and increasing the service life of the steel support body; at the same time, the surface of the exposed spherical steel support is sprayed with epoxy zinc-rich primer, which improves the corrosion resistance of the spherical steel support and further enhances the durability of the spherical steel support; in addition, the size of the spherical steel support can be configured according to the actual project, which is flexible and changeable, safe and reliable, easy to install and disassemble, and has high practicality.
