High-strength anti-cracking anti-deformation plastic window

Abstract

The invention relates to a high-strength anti-cracking anti-deformation plastic window. The plastic window comprises window frames, mullions, an opening fan and hardwares, The upper side, lower side,left side and right side of the outermost layer of the whole window are respectively provided with a window frame and the window frames are connected into an outer frame; the mullions are arranged inthe transverse middle part and the vertical middle part of the outer frame; the window frames, the mullions, the transverse middle part and the vertical middle part of the outer frame are connected into a whole through mullion connecting pieces; the opening fan is formed through plastic special profiles which are arranged in the upper sides, lower sides, left sides and right sides of the window frames and the mullions; and the opening fan is connected with the window frames through the hardwares. The plastic window has the beneficial effects that the existing machining device is not changed, the ingenious design is adopted, the problems that the plastic window fillet is cracked, the mullion connection is not firm and the whole window is deformed are thoroughly solved, the entrance steel lining inspection of the door and window products is realized, 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] With the continuous improvement of the national environmental protection requirements, the external windows of buildings are rapidly followed up by technological upgrading. At present, aluminum windows and plastic windows coexist in the market. The multi-cavity design and manufacture of plastic windows can make the thermal insulation coefficient of the entire window reach 1.0[ W / (m 2 .k)] below, to meet the demand of 80% energy saving, the window price market is relatively recognized, but there are cracks in the welding corners of the window frame, unreliable welding of the middle stile, the whole window collapses and is caused by unscrupulous merchants who do not wear steel linings Problems such as the inability to open the window sash have affected the market prospect of p...
