[0002] In modern architectural design, glass curtain walls are highly favored for their transparent and modern appearance. To meet the building's natural ventilation needs, integrating operable windows into glass curtain wall systems is a common practice, with outward-hung windows being widely used due to their excellent sealing performance and ventilation efficiency. At the same time, outward-hung windows can minimize the size of the operable sash frame, achieving a near-frameless visual effect from the outside. However, inside guest rooms, the sash frame materials on both sides of the glass curtain wall columns and beams near the windows are relatively large and protrude beyond the columns and beams, significantly impacting guests' views and the overall quality of the interior space. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a node design structure for concealing the interior side sash frame material of an externally suspended window in a glass curtain wall.
