AI Technical Summary

Technical Problem

Existing door and window subframe structures can create thermal bridges in winter and summer, leading to excessively rapid heat exchange between indoors and outdoors, increasing the burden on heating and cooling systems, and hindering energy conservation in buildings.

Method used

Multi-cavity thermal insulation strips are added between the outer and inner subframes of doors and windows to block the heat conduction path, and the connection stability is enhanced by pre-embedding the insulation strip hooks in the wall.

Benefits of technology

It effectively blocks thermal bridges, reduces indoor and outdoor heat exchange, lowers energy consumption, improves building stability and connection strength, and ensures comprehensive performance with ultra-low energy consumption.

Abstract

The utility model provides a door and window auxiliary frame structure and a door and window. A hook auxiliary frame comprises an outer side hook auxiliary frame, a hook auxiliary frame heat insulation strip and an inner side hook auxiliary frame. The outer side hook auxiliary frame and the inner side hook auxiliary frame are connected through a hook auxiliary frame heat insulation strip and are pre-embedded in a wall body; the outer side hook auxiliary frame is connected with the outer side face of the door and window outer frame, and the inner side hook auxiliary frame is connected with the inner side face of the door and window outer frame. The groove entering auxiliary frame comprises an outer side groove entering auxiliary frame, a groove entering auxiliary frame heat insulation strip and an inner side groove entering auxiliary frame. The outer side groove-entering auxiliary frame and the inner side groove-entering auxiliary frame are connected through a groove-entering auxiliary frame heat insulation strip and are embedded in a wall body. The outer side groove-entering auxiliary frame is connected with the outer side face of the door and window outer frame, and the inner side groove-entering auxiliary frame is connected with the inner side face of the door and window outer frame. The heat insulation strips are additionally arranged between the inner side structure and the outer side structure of the door and window auxiliary frame, a heat conduction path is blocked, and the comprehensive performance of ultralow-energy-consumption doors and windows is ensured.
