Restrained steel column adapted to micro-deformation of roof structure
By designing constrained steel columns that adapt to the micro-deformation of the roof structure and utilizing the interlocking structure of the column base and column cap, the problem of tensile cracking of the reinforced concrete roof structure by steel columns was solved. This enabled the steel columns to turn within a limited range to adapt to the micro-deformation of the roof structure, ensuring the integrity and safety of the building.

AI Technical Summary
Technical Problem
The micro-expansion or micro-contraction of steel columns constraining reinforced concrete roof structures can lead to tensile cracks in the roof structure, affecting the building quality.
Method used
A constrained steel column was designed to adapt to the micro-deformation of the roof structure. Through the plug-in structure of the column base and column cap, the steel column is allowed to turn within a limited range to adapt to the micro-deformation of the roof structure and avoid tensile cracking.
Benefits of technology
This effectively avoids the problem of roof structure cracking during micro-deformation, ensuring the structural integrity and safety of the building.
