Bridge-cutoff aluminum alloy section heat insulation strip

Abstract

The invention provides a bridge-cutoff aluminum alloy section heat insulation strip which comprises first heat insulation parts with the two ends forming connection edges and second heat insulation parts fastened longitudinally with the first heat insulation parts. Each first heat insulation part and the corresponding second heat insulation part are each of a sheet structure and form a cavity. The two ends of the second heat insulation parts form shield portions completely covering the side of a bridge-cutoff aluminum alloy section, the first heat insulation parts and the second heat insulation parts are of a split structure, and the second heat insulation parts are flexible parts. The first heat insulation parts are used as frameworks to play a supporting role, and external impurities are prevented from entering the bridge-cutoff aluminum alloy section due to the shield portions, completely covering the side of the bridge-cutoff aluminum alloy section, of the second heat insulation parts fastened to the first heat insulation parts; it is ensured that the bridge-cutoff aluminum alloy section has high strength, meanwhile, the heat insulation strip is prevented from being deformed or damaged in the fastened process, and the preparation cost of the bridge-cutoff aluminum alloy section heat insulation strip is reduced.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy profiles, in particular to a heat insulating strip for broken bridge aluminum alloy profiles. Background technique [0002] Broken bridge aluminum alloy window is an improved type based on the old aluminum alloy window to improve the thermal insulation performance of doors and windows. The aluminum alloy profile is divided into inner and outer parts by heat insulation strips to block the heat conduction of aluminum. The material and quality of the reinforced nylon spacers directly affect the durability of the heat-insulated broken bridge aluminum alloy windows. The principle of heat-insulating broken bridge aluminum alloy is to penetrate the heat-insulating strip in the middle of the aluminum profile to effectively prevent the conduction of heat. The door and window frame leaves are made in this way, equipped with hollow glass, hardware, invisible screens, glass glue, foam glue, and sealin...

AI Technical Summary

Problems solved by technology

The IC-type heat-insulation strip 3 effectively solves the disadvantages of the unattractive appearance of the I-type heat-insulation strip and the low mechanical properties of the C-type heat-insulation strip. The cost of the mold used for the heat insulation strip 3 is relatively high, resulting in high manufacturing cost of the heat insulation strip

At the same time, in order to achieve a fully sealed effect, the polyamide heat insulation profile part as hard as the main part must touch the buckle of the aluminum alloy profile to prevent the generation of gaps, so it is very easy to cause the IC type heat insulation strip 3 to be damaged. Aluminum alloy extrusion causes damage or deformation, which reduces the aesthetics and assembly effect
