Multi-composite structure component for doors and windows

Abstract

The invention discloses a multi-composite structure component for doors and windows. Strutting pieces are embedded into a die cavity on the lower part of an outer metal component; the middle part and the lower end of the outer metal component are connected with the upper and lower ends of an inner nonmetal component by connecting pieces extended out of the upper and lower ends of the nonmetal component and connecting piece bayonets on the metal component respectively; the inner side of the inner nonmetal component is provided with the die cavities matched with the other components of the doorand the window; and a heat-preservation layer is filled or injected into the sealed die cavities reserved between the inner nonmetal component and the outer metal component. The multi-composite structure component for the doors and windows has high damage resistance, prolonged service life under the severe environments of solarization, low temperature, high wind, torrential rain or the like, highheat-preservation performance, functions in heat insulation and sound insulation, high energy-saving performance, and usability for the manufacture of frame sections, sash sections, middle support sections or bodies of the doors and windows in extreme temperature areas, such as hot areas, cold areas and the like.

Description

technical field [0001] The invention relates to a multi-composite structural member for doors and windows. Background technique [0002] In hot or cold regions with extreme temperatures, the outdoor side of the doors and windows is often exposed to the sun or low temperature or erosion of strong winds, rainstorms, etc. The damage to the doors and windows, especially the damage to the outdoor side, is very serious, reducing the durability of the doors and windows, especially the doors and windows. frame life. And due to the influence of high temperature or low temperature or strong wind and rainstorm, in order to make the indoor temperature or environment not too much affected by the outdoor temperature or environment, and achieve the purpose of energy saving, it is necessary for the doors and windows to have good temperature insulation, sound insulation effect and good airtightness. And the door and window frame on the existing market generally adopts single metal material,...

AI Technical Summary

Problems solved by technology

And the door and window frame on the existing market generally adopts single metal material, wood material and PVC material to make, and the body of door and window also adopts single metal material, wood material, PVC material to make, and the door and window frame or body that metal material is made , its anti-destructive performance is strong, but its temperature insulation, sound insulation and airtight performance are poor; the door and window frame or body made of wood material and PVC material has good temperature insulation, sound insulation and airtight performance, but its anti-destructive performance is poor
