Double-cavity heat-insulating and temperature-preserving inward casement window structure

Abstract

The invention relates to the technical field of processing of combination of casement screen windows and casement windows, in particular to a double-cavity heat-insulating and temperature-preserving inward casement window structure. Specifically, cross sections of a primary frame structure and a secondary frame structure of an original window frame are changed from single-surface contact into double cavities, and the single-surface contact of the cross sections of contact glass of original window sashes is realized as the double cavities; the single-surface contact of a contact glass part of the original window frame is realized as a double-cavity cross section, and the double-cavity cross section is filled with a temperature preserving material, so that the heat preserving property, the load capacity and the wind pressure resistance of a primary frame body and a secondary frame body of a window frame are improved by the cavities of the window frame and a wall surface; the temperature preserving property of the glass contact surfaces of the window sashes is improved, so that the heat-insulating and temperature-preserving effects are improved, and the purpose of reducing a heat transfer coefficient K is achieved. The reasonable arrangement of a combined structure of a screen window and the window frame in a window frame body is realized.

Description

technical field [0001] The invention relates to the technical field of combined processing of a casement screen window and a casement window, in particular to a heat-insulating inner casement window structure in which an inner casement screen window and an inner casement window of a double-cavity structure are combined into one. Background technique [0002] With people's perfect pursuit of the comfort of modern life, higher requirements are put forward for doors and windows, especially the combination of casement screen windows and casement windows has launched a number of series of products, such as the applicant proposed a number of patents (CN201620007335 .0, CN201620006908.8, CN201520467227.7, etc.), the demand for energy-saving and emission-reduction of doors and windows has become more prominent in the recent market.

[0002] With people's perfect pursuit of the comfort of modern life, higher requirements are put forward for doors and windows, especially the combination of casement screen windows and casement windows has launched a number of series of products, such as the applicant proposed a number of patents (CN201620007335 .0, CN201620006908.8, CN201520467227.7, etc.), the demand for energy-saving and emission-reduction of doors and windows has become more prominent in the recent market. The existing broken-bridge heat-insulated aluminum alloy casement windows only have one-sided contact between the window frame profile and the glass. The material of the window frame is limited by the aluminum profile, and the window frame profile itself does not form a cavity for heat preservation, and the heat transfer coefficient K value is reduced only by the heat insulation strip

At present, the above method can only change the heat transfer coefficient K value by a single heat insulation strip, and cannot reduce the heat transfer coefficient K value through multiple channels.
