High energy-saving heat preservation aluminum-plastic combined window

Abstract

The invention relates to a high energy-saving heat preservation aluminum-plastic combined window. The high energy-saving heat preservation aluminum-plastic combined window comprises window frames, opening sashes and mullions; the window frames at the top, the bottom, the left and right correspondingly of an outer layer of the whole window are connected to form an outer frame; the window frames arecombined by L-shaped bridge-cutoff aluminum alloy profiles and U-shaped plastic profiles into a multi-cavity structure; the mullions are arranged in the horizontal middle parts and the vertical middle parts of the outer frame and are combined by T-shaped bridge-cutoff aluminum alloy profiles and U-shaped plastic profiles into a multi-cavity structure, and the mullions and the window frames are connected into a whole through connecting pieces; the open sashes are formed by connecting the plastic profiles at the top, the bottom, the left and right in the outer frame and the mullions, and the open sashes are connected to the window frame by hardware. According to the high energy-saving heat preservation aluminum-plastic combined window, the cavity structure of the plastic profiles is adoptedto increase the high heat preservation performance; the overall configuration improves the heat preservation effect of the whole window; an ingenious design is adopted, the characteristics of high strength, aging resistance and beautiful appearance of the bridge-cutoff aluminum alloy profiles are taken into account, so that the heat preservation performance of the whole window meets the nationalenergy-saving requirements, the cost of the whole window is optimized, and the market promotion is facilitated.

Description

technical field [0001] The invention relates to the technical field of construction industry, in particular to energy-saving doors and windows in the construction industry. Background technique [0002] In the development process of building exterior windows, steel windows replaced wooden windows, aluminum windows replaced steel windows, plastic windows replaced aluminum windows, and broken bridge aluminum windows and plastic windows coexist in the current market. Broken bridge aluminum alloy windows combine nylon insulation strips with aluminum profiles through technological innovation to achieve market demand characteristics such as heat insulation, high strength, aging resistance, and beautiful appearance, but the material cost is greatly increased due to the reduction of the thermal insulation coefficient of the material. The market is difficult to accept. Through the multi-cavity design and manufacture of plastic windows, the thermal insulation coefficient of the whole...

Problems solved by technology

Broken bridge aluminum alloy windows combine nylon insulation strips with aluminum profiles through technological innovation to achieve market demand characteristics such as heat insulation, high strength, aging resistance, and beautiful appearance, but the material cost is greatly increased due to the reduction of the thermal insulation coefficient of the material. The market is difficult to accept

Through the multi-cavity design and manufacture of plastic windows, the thermal insulation coefficient of the whole window can reach 1.0 [W / (m 2 .k)] below, to meet the demand of 80% energy saving, but there is the problem of cracking of the welding angle of the window frame, resulting in a decrease in the insulation effect

Aluminum-wood combined doors and windows on the market can meet the energy-saving requirements of passive buildings, but the cost of the whole window is higher, and there are many processing steps, so it cannot be widely used in the market
