AI Technical Summary
In traditional curtain wall systems, exposed frame curtain walls affect the aesthetics of the building facade, while concealed frame curtain walls are prone to leakage due to aging of the sealant joints and have high maintenance costs. Existing joint treatments are prone to failure and require large-scale removal of panels.
The curtain wall adopts a vertical exposed and horizontal concealed composite structure. Through multiple sealing designs and flexible connections, it combines vertical exposed frames and horizontal concealed frames, and uses indoor and outdoor sealing strips, foam rods and sealing strips for sealing. It is also connected to the plug-in through the hollow structure of the horizontal beam to form a rigid node that is resistant to shear and torsion.
It enhances the aesthetics of the building facade, prevents leakage, reduces maintenance costs, strengthens structural stability, facilitates maintenance, and allows glass replacement without damaging the overall structure.
