Energy-saving, environment-friendly, broken-bridge and heat-insulating aluminum alloy doors and windows

Abstract

The invention discloses energy-saving, environment-friendly, broken-bridge and heat-insulating aluminum alloy doors and windows. The frames, the mullions and the fan frames of the doors and windows are respectively composed of outdoor and indoor aluminum profiles and heat insulating strips. The heat insulating strips include three structures: a heat insulating strip A for the frames of identical width, a heat insulating strip B for the mullions and a heat insulating strip C for the fan frames. The heat insulating strips A, B and C, heat insulating supporting rubber strips and constant-pressure rubber strips are in multi-cavity structures. Outdoor insulating glass is fixed through outside sealing rubber strips in a press-joint manner, indoor insulating glass is fixed through inside sealing rubber strips in a press-joint manner, the middle is fixedly supported by insulating supporting rubber strips, the insulating supporting rubber strips are fixedly connected with the heat insulating strips A, B and C respectively, and the insulating strip B is fixedly connected with the insulating strip C by the aid of the constant-pressure rubber strips. The energy-saving, environment-friendly, broken-bridge and heat-insulating aluminum alloy doors and windows are fine in waterproofing, heat and sound insulating effects, and high in energy saving rate and can meet national or regional demands for energy conservation.

Description

technical field [0001] The invention belongs to the field of building doors and windows, and relates to an aluminum alloy energy-saving and environment-friendly door and window. Background technique [0002] At present, the doors and windows used in construction projects need to meet the energy-saving standards of 50% or 65% according to the energy-saving indicators of the country or various regions, and the energy-saving indicators of some areas need to reach 70%, which means that the energy-saving coefficient K of building doors and windows is required to be below 2.0 , These show that the thermal insulation performance index has become an important index to measure the performance of doors and windows. But at present, ordinary aluminum alloy doors and windows have serious shortcomings: 1. There is a gap between the aluminum alloy profile and the glass, which is easy to form convection; 2. The section design of the equal pressure strip between the frame and the fan is simp...

AI Technical Summary

Problems solved by technology

But at present, ordinary aluminum alloy doors and windows have serious shortcomings: 1. There is a gap between the aluminum alloy profile and the glass, which is easy to form convection; 2. The section design of the equal pressure strip between the frame and the fan is simple, and the ability to prevent heat conduction is small; 3. The hollow glass air cavity and the heat-insulating aluminum profile heat-insulation cavity are not on the same isotherm, and the outer glass and the inner profile form strong heat radiation; 4. Because water has the characteristics of tension, it is difficult for water to Exhausting the cavity of the profile will easily cause water leakage; 5. Due to the poor coordination effect of the hardware, accessories and other accessories on the door and window with the profile of the door and window, the sealant strip is used to seal between the profile and the hinge, and the hinge and the sealant The coordination effect between the strips is poor, resulting in poor overall sealing performance of doors and windows

Due to the above shortcomings, the radiation and thermal conductivity of ordinary aluminum alloy doors and windows are too large, which cannot meet the energy-saving needs of the future development of the market and the industry, and may easily cause water leakage.
