Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profiles for doors and windows, specifically a thermally insulated and soundproof thermally broken aluminum profile. Background Technology

[0002] Thermally broken aluminum profiles, also known as heat-insulating and sound-insulating profiles, offer superior heat and sound insulation compared to ordinary profiles. The "bridge" refers to the thermal bridging in materials science. Aluminum alloy is a metallic material with a high rate of heat and sound transfer. When indoor and outdoor temperatures differ significantly, direct heat exchange and sound transmission easily occur. By cutting the aluminum profile into two parts and installing a plastic retaining strip between them, the density of the strip is lower than that of aluminum alloy. This reduces heat and temperature loss when sound and temperature are transferred between media of different densities, thus achieving heat and sound insulation effects and a better user experience. This has made thermally broken aluminum profiles a crucial component in current building door and window profiles.

[0003] Currently, most thermally broken aluminum profiles have the indoor and outdoor connection surfaces located on the same vertical plane, usually in the middle of the aluminum profile. In general, the anti-aging properties and strength of plastic strips are inferior to those of aluminum alloy profiles. During use, such as in sliding windows and doors, where two doors and windows slide sideways with one inside and one outside, the plastic strips on the thermally broken aluminum profiles located below and on the sides of the inner doors and windows are exposed to the outside, directly subjected to wind, sun, rain, and snow, resulting in severe corrosion, accelerated aging of the plastic strips, and reduced overall lifespan. Utility Model Content

The hard plastic thermal insulation strip is protected on the inside, preventing erosion from wind, sun, rain, and snow, thus delaying aging and extending the overall service life.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] The outer connecting part is located above the inner connecting part. The opposite surfaces of the inner main body and the outer connecting part, as well as the opposite surfaces of the inner connecting part and the outer main body, are respectively provided with slots.

[0014] Preferably, there are multiple hard plastic support strips, and adjacent hard plastic support strips are arranged in a figure-eight and a V-shape.
