Description

Technical Field

[0001] The utility model relates to the technical field of door and window profile manufacturing, in particular to a heat-insulating broken bridge structure for doors and windows. Background Art

[0002] The "bridge" in "thermal-insulation thermal-bridge structure" refers to the "cold-hot bridge" in the materials science sense, and "broken bridge" means "breaking the cold-hot bridge." The thermal-bridge structure used in door and window frames involves splitting the aluminum alloy profile in the middle and connecting it with hard plastic. Due to the low thermal conductivity of hard plastic, this acts as a thermal-bridge. The aluminum alloy profiles in this thermal-insulation thermal-bridge structure provide Erzhi doors and windows with superior thermal insulation and heat preservation.

[0003] For example, CN 219101087 U discloses a thermally insulated thermal bridge structure system door and window, comprising a first thermal bridge frame and a second thermal bridge frame. A hard plastic connector is fixedly mounted on one side of the first thermal bridge frame below. Double-layer tempered glass is fixedly mounted on one side of the first thermal bridge frame above. A fixing plate is fixedly mounted below the double-layer tempered glass. A first sound insulation foam is clamped to one side of the second thermal bridge frame. A desiccant is fixedly mounted inside one side of the first thermal bridge frame. A sealing strip is provided on one side of the first thermal bridge frame below. A first clamping block is fixedly mounted above the sealing strip above the middle of the sealing strip. A second clamping block is fixedly mounted above the middle of the sealing strip. A first sealing strip is clamped to one side of the second clamping block. This door and window utilizes the sealing strip, the first and second sealing strips, and the desiccant filled within the first and second thermal bridge frames to improve overall sealing and waterproofing performance. However, there are issues with its use: the hard plastic connector, which achieves the thermal bridge function, has a small cross-sectional area, resulting in low connection strength.
