Detailed Description
The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
Example 1 of the invention: an adjustable connecting device for a special-shaped steel arch center is shown in figures 1-4 and comprises 1 upper structure mounting plate 1, wherein 1 sphere device 2 is fixedly arranged at the center of the bottom surface of the upper structure mounting plate 1, and the middle of the top surface of the upper structure mounting plate 1 is connected with an upper structure connecting plate 4 through 1 connecting column 3; the device is characterized by further comprising 1 lower structure mounting plate 5, wherein 1 bearing column 6 is fixedly arranged on the top surface of the lower structure mounting plate 5, 1 spherical groove 7 is formed in the top surface of the bearing column 6, and the size of the spherical groove 7 is slightly larger than that of the sphere device 2, so that the sphere device 2 can be placed in the spherical groove 7. The center of the bottom surface of the lower structure mounting plate 5 is fixedly connected with a lower structure connecting plate 8 through a connecting column 3. Bolt holes 10 corresponding to the positions are arranged on the upper structure mounting plate 1 and the lower structure mounting plate 5. When the upper structure and the lower structure are connected with each other, the upper structure and the lower structure can be connected together by connecting bolts 9 penetrating through bolt holes 10 on the upper structure mounting plate 1 and the lower structure mounting plate 5.
In the use process, a lower structure connecting plate 8 in a lower structure of the device is welded with a web plate of a large-size main arch, then a sphere device 2 of an upper structure is placed in the spherical groove 7, and a connecting bolt 9 penetrates into bolt holes 10 of an upper structure mounting plate 1 and a lower structure mounting plate 5, but the upper structure mounting plate and the lower structure mounting plate are not screwed. And then adjusting and screwing the connecting bolt 9 to enable the upper structure connecting plate 4 of the upper structure to be parallel to the end face of the small-size oblique-section steel arch, and then welding and connecting the upper structure connecting plate 4 with the end face of the oblique-section steel arch.
