AI Technical Summary

Technical Problem

Existing inward-opening awning windows lack airtightness and aesthetics in double-layer curtain walls, especially since inward-opening awning windows are fixed by the opening pressure line, resulting in poor sealing and appearance.

Method used

The design adopts a concealed sash profile. The inward-opening awning window forms a multi-level sealing structure by processing a step on the inner window frame and embedding the inward-opening glass, combined with hollow sealing strips and sound insulation sealing strips. The outward-opening awning window ensures airtightness through L-shaped locking and hollow sealing strips. The outward-opening glass is embedded in the extension section to maintain a consistent appearance.

Benefits of technology

It improves the airtightness, sound insulation, and heat insulation of the double-layer curtain wall, enhances its aesthetics, and ensures a unified appearance for both the interior and exterior windows.

Abstract

This utility model belongs to the field of door and window technology, and discloses a concealed sash profile for double-layer curtain walls, including a support column, a crossbeam, an outer frame, an inner frame, an outward-opening awning window, and an inward-opening awning window. The outer frame and inner frame are symmetrically fixed on the support column. Crossbeams are installed on the outer frame and inner frame. Decorative cover plates connecting the outer frame and inner frame are installed on both sides of the support column. The outward-opening awning window is installed inside the outer frame, and the inward-opening awning window is installed inside the window opening of the inner frame. The inward-opening awning window includes an inner window frame, an inner sash frame, and inward-opening glass. A thermal break structure is installed on the inner window frame, and a baffle is processed on the inner window frame. The inner sash frame is connected to the inner window frame, and a step is processed on the outer side wall of the inner sash frame. The inward-opening glass is embedded in the step, and a hollow sealing strip that fits with the inward-opening glass is installed at the end of the baffle. This utility model processes a step on the inner sash frame and embeds the inward-opening glass in the step. With the help of a hollow sealing strip and a soundproof sealing strip, a multi-level seal can be formed, thereby ensuring the sound insulation and heat insulation effect of the double-layer curtain wall.
