Description
Technical Field
The utility model relates to the technical field of doors and windows, in particular to a high-performance aluminum-coated plastic system door and window structure.
Background
The door and window is used as the main part of the outer enclosure of the building, and is the most active and sensitive part of heat exchange and heat conduction of the building. The heat insulation performance of the common building outer door and window is much poorer than that of the outer wall, and as a weak link of building heat insulation, the building outer door and window must have good heat insulation and energy saving performance.
The plastic-steel door and window is a door and window type commonly used in high-energy-saving buildings, and in order to improve the heat insulation performance of the plastic-steel door and window to a greater extent and reduce the heat transfer coefficient, the high-grade plastic-steel door and window is usually provided with middle constant-pressure large adhesive tapes on frame and stile section bars, and adopts three sealing structures. When the window sash is closed, the rubber strip is in sealing fit with the casement window sash, so that two cavities, namely a water-vapor mixing chamber and an independent airtight chamber, are formed between the frame window sash, and the heat loss caused by air convection is reduced due to the independent airtight chamber.
The conventional three-sealing structure still uses the design concept of the traditional 12mm hardware activity space, so that the middle sealing part is an oversized middle adhesive tape, but the specially-made adhesive tape is often designed and purchased independently, has high requirements on the material and the service performance of the adhesive tape, and needs to ensure that the sealing effect is not lost after long-time use; or the bosses are designed on the frame and stile profiles to lift the middle sealing rubber strips, but the method for lifting the rubber strips also leads to the fact that the frame and stile profiles have to use a specially-made glass mat bridge when being used as a fixed window, and even a part of profiles have to be milled for use, so that the processing procedure is complicated, and the cost is higher.
In addition, although the traditional three-sealing structure has an independent airtight chamber, the air tightness is greatly improved, because the traditional 12mm hardware movement space design is adopted, the airtight chamber space is still large, the width is 17mm, and the lap joint amount of the frame and the fan at the indoor side is only 8mm, the heat loss caused by air convection still exists.
