Broken bridge heat insulation aluminum alloy casement window

Abstract

A broken bridge heat insulation aluminum alloy casement window comprises a window frame sectional material, a window sash sectional material, a middle stile sectional material and a trim strip sectional material. The window frame sectional material is composed of an LYJGR6501G assembly and an LYJGR6501R assembly. The window sash sectional material comprises an outer support and an inner support and is composed of an LYJGR6502G assembly and an LYJGR6502R assembly. The middle stile sectional material is composed of an LYJGR6503G assembly and an LYJGR6503R assembly, wherein the LYJGR6503G assembly is provided with a closed fifth cavity, and the LYJGR6503R assembly is provided with five closed cavities, namely, the sixth cavity, the seventh cavity, the eighth cavity, the ninth cavity and the tenth cavity. According to the broken bridge heat insulation aluminum alloy casement window, mounting, lap joint and heat insulation, closed and waterproof construction of holes and a window frame arefacilitated, the number of the cavities and the sizes of glass groove openings are ensured, and high properties of water tightness, air tightness and heat insulation are achieved; particularly, losingof cold and warm air flows from the groove openings is delayed, and the effects of heat insulation and sound insulation are improved; a drainage system is designed through the pressure balancing principle, a frame stile structurally achieves the water dark discharging function, rainwater is discharged into dark cavities, and through the natural pressure in the cavities, drainage is conducted, sothat the air tightness, water tightness and dustproof function of an opening sash are improved.

Description

technical field [0001] The invention relates to an aluminum alloy casement window, in particular to a broken bridge heat-insulating aluminum alloy casement window. Background technique [0002] The development of green buildings and the promotion of building energy conservation are major deployments of my country's energy strategy. At present, the energy consumption of doors and windows accounts for about 48-65% of the energy consumption of the entire building and 20% of the total energy consumption of the society. Compared with the national commitment to reduce carbon emissions per unit of GDP by 40%-45% in 2020, the energy consumption data from the construction sector is shocking. Among the many urban buildings in our country, more than 97% are high energy consumption buildings. It is estimated that by 2020, the national high-energy consumption building area will reach 70 billion square meters, and building energy conservation is imperative. Building energy conservation...

Problems solved by technology

[0004] At present, the above-mentioned broken bridge heat-insulating aluminum alloy window has a two-cavity structure, which has poor sealing performance and cannot really achieve high-performance air-tightness, water-tightness and heat insulation; the low frame is inconvenient for the opening and the window frame. Installation lap joints and thermal insulation, sealing and waterproofing during construction; there is no drainage groove with hidden drainage function on the frame stiles, so watertightness, airtightness and sound insulation performance cannot be guaranteed; the overlap of frame fans and rubber strips is low, The joints are not tight enough to improve the heat insulation, heat preservation, waterproof and airtight functions of aluminum alloy profiles

To sum up, the heat-insulated aluminum alloy window of the broken bridge is not effective in wind and sand resistance, wind pressure resistance, heat insulation, heat preservation and waterproof airtightness, and cannot be used for high-rise buildings and large-area window designs.
