Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation strips, and more specifically to a combined thermal insulation strip inside an aluminum alloy frame for doors and windows. Background Technology

[0002] Thermal break strips are a core component of thermally broken aluminum windows and doors, and their performance directly affects the heat insulation, thermal insulation, sound insulation, and structural safety of the windows and doors. Currently, windows and doors typically have two thermal break strips, installed on the inner and outer sides of the window and door frame using a snap-fit ​​method. There is generally no supporting connection between the two sets of thermal break strips; they are mainly positioned and supported by the inner and outer edges of the window and door frame. Therefore, when the thermal break strip is impacted (mainly the outer strip), if the side of the thermal break strip is close to the window and door frame, the frame can prevent the thermal break strip from deforming, resulting in minimal deformation and making it less likely to detach from the frame. However, if the impact is located in the middle of the thermal break strip, the deformation is greater, easily causing the side of the thermal break strip to detach from the window and door frame or causing damage to the middle of the thermal break strip. Therefore, it is necessary to have a structure between the two thermal break strips to effectively connect and support them. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a combined thermal insulation strip for aluminum alloy frames of doors and windows. The combined thermal insulation strip consists of two sets of thermal insulation strips and honeycomb support strips set between the thermal insulation strips.
