Insulated sliding window

Abstract

The invention relates to a heat insulation type sliding window comprising a window frame, an inner window sash and an outer window sash. The window frame is provided with an upper slide, a lower slide, a left jamb and a right jamb. Each of the inner and outer window sashes is provided with an upper square, an outer lower square, an inner lower square, a smooth rabbet and a hooked rabbet; the hooked rabbet of each of the inner and outer window sashes is provided with an inner profile and an outer profile which are connected through two heat insulating bars, bar penetrating clamp slots for clamping the ends of the heat insulating bars are formed in the inner and outer profiles, the profiles of hooking surfaces of the hooked rabbet are provided with glue injecting cavities used for injection of glue solution, each glue injecting cavity is arranged between every two heat insulating bars, the wall of the glue injecting cavity of the hooking surface of each hooked rabbet is provided with a glue injection opening, the wall of each glue injecting cavity opposite to the corresponding glue injection opening is provided with a heat insulation fracture, and the profile of the hooking surface of each hooked rabbet is partitioned into a left part and a right part through the corresponding glue injection opening and the heat insulation fracture. Each hooked rabbet is completely divided into three parts by adopting a broken bridge mode combining bar penetration and glue injection, heat transfer coefficient of the whole window is lowered, the heat transfer coefficient K-value can reach 1.6-2.4 according to different used glass, and the requirements on heat insulation performance of linear standard doors and windows promoted in Jiangsu Province are met.

Description

technical field [0001] The invention relates to a sliding window, in particular to a heat-insulating sliding window. Background technique [0002] According to the standardized external window system of newly-built, renovated and expanded residential buildings in Jiangsu Province, new requirements are put forward for the existing sliding windows made of aluminum alloy, plastic, glass-steel grade one aluminum-wood composite and other materials. The physical and thermal performance indicators of the standardized external window system have the following requirements: the wind pressure resistance performance shall not be less than grade 3 for 9 floors and below, and shall not be less than grade 4 for 10 floors and above; the airtightness requirement shall not be less than grade 6; The performance is not less than grade 3, the heat transfer coefficient K value is not less than grade 6 and not higher than 2.4W / (m 2 · K). [0003] However, most of the existing aluminum alloy sli...

Problems solved by technology

[0003] However, most of the existing aluminum alloy sliding windows do not meet the above requirements. They are sealed with double wool strips or rubber strips, causing serious air leakage and water seepage. High; especially the K value coefficient, the standard configuration is 5+A6+5+A6+5 insulating glass, which cannot meet the requirements of standardized system windows
