AI Technical Summary

Technical Problem

In large buildings, the existing light steel keel partition wall system lacks sufficient stiffness and strength in ultra-high situations, which may cause the wall to deform or become unstable, making it difficult to meet the lateral force resistance requirements of tall spaces.

Method used

The system adopts a support frame system, including structural columns, structural beams and keel units, forming a composite support frame of "steel frame + light steel keel". The structural columns support the floor slab and steel structure beams, and the structural beams are connected to form a frame opening. Multiple keel units are set at axial intervals in the frame opening to enhance the overall rigidity and lateral force resistance.

Benefits of technology

It effectively solves the problem of insufficient rigidity and strength of light steel keel in ultra-high situations, ensuring the stability of the wall. It is suitable for ultra-high and large-space walls with a maximum height of about 17.7m and a maximum span of about 80m, improving construction efficiency and safety, and reducing construction costs and complexity.
