Working principle of the present invention:

The column of the present invention is supported on the column base on the ground, and the column and the column base are connected by high-strength bolts, and the roof steel strands, load-sharing balance steel strands, and side-slip steel strands pass through the support arm anchor pipe and the sheave Supported on the column, the ground anchor steel strand is stretched between the ground anchor and the anchor pipe of the support arm. After being tensioned on the anchor pipe of the arm, the tension on the other steel strands is balanced. The movement of the steel strands in the sheave makes the roof of the factory building a stable structure that can be reasonably stretched; the rotation of the anchor pipe of the support arm reduces the influence of the deformation of the roof on the columns due to load changes. The diagonal tension of the anti-sideshift steel strands reduces the lateral movement of the roof, and the force synchronization bar between the roof steel strands and the load-sharing balance steel strands makes the roof more evenly stressed. The joint action of the supporting beams between the columns and the anti-sway steel strands enhances the longitudinal stability of the columns, and the connection between the protective tube and the lower shear braces enhances the lateral stability of the columns, providing conditions for the installation of the driving on the columns.

Although the specific implementation of the invention has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the present invention. On the basis of the technical solution of the present invention, those skilled in the art can make various Modifications or variations are still within the protection scope of the present invention.
