Aluminum plastic combined section for high-energy-saving heat-preservation doors and windows

Abstract

The invention relates to an aluminum plastic combined section for high-energy-saving heat-preservation doors and windows. The aluminum plastic combined section for the high-energy-saving heat-preservation doors and windows comprises an aluminum plastic combined flat-opening frame structure and an aluminum plastic combined mullion structure, wherein the aluminum plastic combined flat-opening framestructure is of an L-shaped structure formed by an inner-side multi-cavity aluminum plastic combined flat-opening frame plastic profiled bar, an outer-side aluminum plastic combined flat-opening framebridge-cutoff aluminum alloy section and a fastener; and the aluminum plastic combined mullion structure is of a T-shaped structure formed by an inner-side multi-cavity aluminum plastic combined mullion plastic profiled bar, an outer-side aluminum plastic combined mullion bridge-cutoff aluminum alloy section and a fastener. According to the aluminum plastic combined section for the high-energy-saving heat-preservation doors and windows provided by the invention, an aluminum material and a plastic material are mainly utilized for manufacturing a multi-cavity structure, a convex-concave structure design is combined with the outer fasteners, the whole doors and windows achieve a high energy-saving performance of plastic profiled bar doors and windows and high strength and corrosion resistance of bridge-cutoff aluminum alloy doors and windows after assembling, and meanwhile, the sales unit price is lower than the price of the bridge-cutoff aluminum alloy doors and windows, so that the aluminum plastic combined section for the high-energy-saving heat-preservation doors and windows is a trend product for old house modification and new house decoration in the future.

Description

The width of the heat strip can meet the energy-saving requirements...

AI Technical Summary

Problems solved by technology

Broken bridge aluminum doors and windows combine thermal insulation strips and aluminum profiles through technological innovation to meet market demands such as thermal insulation, high strength, aging resistance, and beautiful appearance. The width of the heat strip can meet the energy-saving requirements, but the reduction of the thermal insulation coefficient will greatly increase the material cost

Through the multi-cavity design and manufacture of plastic doors and windows, the thermal insulation coefficient of the whole window can reach below 1.0, which can meet the energy-saving requirements of 80% and meet the energy-saving requirements of passive buildings for building doors and windows. Reduced insulation effect

Aluminum-wood composite doors and windows can meet the energy-saving requirements of passive buildings, but the high cost and complicated processing cannot be widely used in the market
