Curtain Wall Structure with Improved Insulation and Structural Performance

摘要

The present invention relates to a curtain wall structure (CS) with improved heat insulation and structural performance. To this end, the present invention is a curtain wall structure for providing a glass panel in front of a main profile constituting a vertical frame or a horizontal frame, in which a pair of flange portions protrude forward on both sides of the front portion to form a space between the flange portions An additional main profile provided; A thin plate-type insulating plate provided in the space; An aluminum reinforcing bar formed in a lattice-shaped cross section so as to provide a plurality of air cells and provided in the space in a state in contact with the heat insulating plate; And a middle supporter provided in front of the aluminum reinforcing bar to support the glass panel. Accordingly, the present invention can completely block the thermal bridge phenomenon to secure thermal insulation performance, and at the same time, structural stability can be expected.
