Description

Technical Field

[0001] This utility model relates to the field of double-steel insulated glass, specifically to a double-steel structure for insulated glass. Background Technology

[0002] Insulating double-glazed windows are glass components made by bonding two panes of glass together using a high-strength, high-airtightness composite adhesive. The glass panes are then bonded to an aluminum alloy frame containing a desiccant. The resulting glass offers high-performance sound and heat insulation. The thermal insulation performance of insulating double-glazed windows depends not only on the materials used but also on the steel structure design. For example, a heat-insulating double-glazed window with energy-saving features (application number 201710304165.1) has an installation groove in the window sash. The insulating glass is inserted into the groove, and a fixing strip is installed at the interface between the insulating glass and the groove. Additionally, fixing tape is installed at the front edge of the insulating glass. While the simple sealing method using fixing strips or tape can seal the gaps between the insulating glass and the installation groove to a certain extent, achieving a certain degree of thermal insulation, this approach is flawed. However, the connection between the fixing strip or tape and the insulated glass is unstable. After long-term use, the fixing strip or tape will age, which can easily lead to a decrease in the tightness between the window frame and the insulated glass, resulting in poor heat insulation and thermal insulation performance.
