Indoor side molding colored aluminum window

Abstract

Available forged aluminum alloy door and window may have cracks and thus lower sealing performance. The present invention has aluminum section door and window frame of aluminum section with bayonet structure capable of admitting size change caused by machining error and temperature change, connecting board structure and indoor subsidiary frame. The present invention solves the sealing problem of aluminum alloy door second window frame and makes the aluminum alloy door and window frame heat insulating, watertight, and with metal texture.

Description

Technical field: [0001] The invention relates to a building door and window, which belongs to the field of door and window manufacturing. Background technique: [0002] Heat-insulating aluminum alloy doors and windows have a wide market in the high-end real estate industry, but the thermal insulation coefficient of the frame material is low, and the engineering guarantee ability of watertightness at the corners is low: during manufacturing, handling, installation, use, etc., it is very easy to make the corners There is a gap of 0.2 mm, and under the action of 100 Pa wind pressure, it will infiltrate water, making it impossible to become a high-performance door and window. Patent 03219886.8, its technical features: set a colored aluminum shell on the surface of the plastic profile that constitutes the plastic door and window, and design bayonets on both sides of the aluminum shell, so that the aluminum shell is stuck on the "surface of the plastic profile that constitutes the...

AI Technical Summary

Problems solved by technology

The applicability of these technologies is very low: ①This technology does not solve the problem that the thermal elongation rate of aluminum and plastic is 3 times different, and the surface of the dark window in summer can reach a high temperature of more than 60 degrees. The material falls off or the aluminum material breaks the plastic window profile

② The manufacturing process of the window is extremely demanding, which cannot meet the real estate engineering requirements for mass production (one and one rod are required)
