Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation strips used for thermally-insulated aluminum alloy doors and windows, in particular to a heat preservation and enhanced heat insulation strip and a door and window with the heat preservation and enhanced heat insulation strip. Background Art

[0002] In order to improve the heat insulation and thermal insulation effect of aluminum alloy doors and windows, thermal insulation strips are installed during the processing of broken bridge aluminum alloy profiles, thereby improving the heat insulation and thermal insulation effect of aluminum alloy doors and windows. However, the existing heat insulation strips have a simple structure, mostly a single-layer structure, and a poor heat insulation effect. At the same time, in order to improve the energy-saving coefficient of the existing broken bridge aluminum alloy doors and windows, the width of the heat insulation strip passed through the middle of the broken bridge aluminum alloy profile can only be increased. After the width of the heat insulation strip is increased, there are problems such as the shear force of the broken bridge aluminum alloy profile not meeting the standard and deformation under pressure.

[0003] In order to solve the above problems, there are many types of multi-chamber insulation strips in the current market, such as Figure 6 and Figure 7 As shown, in Figure 6 The material of the middle thermal insulation filling layer (2) is soft and easily deformable foam cotton, which only has a thermal insulation effect and does not enhance the structural strength; Figure 7 The first receiving arm (11) and the second receiving arm (12) are made of heat-insulating nylon strips, which have a poor heat-insulating effect and require a high production environment. They are easily affected by external factors, resulting in a loose fit with the window sash aluminum profile (31) and the window frame aluminum profile (32) or difficulty in penetration.

[0004] To this end, we propose a thermal insulation strip and doors and windows having the thermal insulation strip. Utility Model Content
