METHOD FOR MANUFACTURING THERMALLY INSULATED CLOSED-FORM STRUCTURES Russian patent published in 2022 - IPC B29C63/00 

FIELD: thermally insulating structures.

SUBSTANCE: invention relates to methods for manufacturing thermally insulated closed-form structures and can be used in various industries, including in the production of window frames, door frames, in devices during operation of which a temperature difference occurs, for example in cold rooms and air conditioners, seals, in building structures in the production of floorings, fences or profiles for rebuilt premises. The method consists in shaping the profile chamber elements, placing the heat insulator in the corresponding chambers of the profile elements, and the final assembly of the closed structure. Moreover, fibrous, or granular, or foamy thermal insulation material is used as a heat insulator, while when using fibrous thermal insulation material, the latter is placed in the corresponding chambers of profile elements prior to the assembly process, and when using granular or foamy thermal insulation material, technological holes designed to fill the chambers of profile elements with the appropriate heat insulator are pre-installed in the profile elements. Further, the granular or foamy thermal insulation material is sequentially placed in the chambers of the profile elements after the assembly process of the closed structure, and after filling the chambers of the profile elements of the structure with granular or foamy thermal insulation material, the technological holes in the profile elements are sealed.

EFFECT: expanding the arsenal of technical means by creating a method for manufacturing hermetically insulated closed-form structures, the characteristics of which meet the requirements for providing specified thermal insulation properties.
