AI Technical Summary
Technical Problem
Existing cold bent glass units have complex frame structures that require multiple parts, leading to poor workability during assembly and increased risk of damage at joints due to load concentration.
Method used
An aluminum frame for curtain walls with a symmetrical arrangement of tapping holes in relation to the centroid, allowing the frame to be twisted or bent as a whole, eliminating the need for multiple members and distributing load evenly across tapping holes.
Benefits of technology
The solution results in improved workability by simplifying assembly and reducing the risk of damage to specific parts, ensuring even load distribution and enhanced structural integrity during bending or twisting.

Abstract
To provide a glass unit frame for a curtain wall constructed using the cold vent method, and a glass unit for a curtain wall constructed using the cold vent method, which is constructed using a simple aluminum frame and prevents the concentration of load on a part of the aluminum frame. [Solution] An aluminum frame 10 for a curtain wall that supports glass 30 and is twisted or bent together with the glass by a cold venting method, having a plurality of tapping holes H11, H12, H13, H14 for connecting and framing each other, wherein the plurality of tapping holes are arranged in a positional relationship that is symmetrical with respect to the centroids P1, P2, P3 in a cross-sectional view perpendicular to the surface of the glass 30.
