Corner structure of wood flour and plastic doors and windows

Abstract

The invention discloses a corner structure of wood flour and plastic doors and windows, relating to the field of wood flour and plastic doors and windows. The corner structure of the wood flour and plastic doors and windows is provided with window and door lateral profile and window and door transverse profile which is perpendicular to the window and door lateral profile. The windows and door lateral profile is provided with a first solid wood core and a first wood flour and plastic coating layer. The window and door transverse profile which is perpendicular to the window and door lateral profile is provided with a second solid wood core and a second wood flour and plastic coating layer. At least one end of the window and door lateral profile is provided with a first end assumed an intersection angle with flank of the windows and door lateral profile. The first solid wood core of the first end is provided with tenon shaped lug consistent with the length direction of the window and door lateral profile. At least one end of the window and door transverse profile is provided with a second end face assumed an intersection angle with flank of the windows and door transverse profile. At least one end of the window and door transverse profile is provided with a second end assumed an intersection angle with flank of the windows and door transverse profile. The second solid wood core of the second end face is provided with groove recessed portion which coincides with the tenon shaped lug. The corner structure of wood flour and plastic doors and windows has the advantages of providing bonding strength for the corner structure of doors and windows through utilizing the characteristic of solid wood composite section profile cladded by the wood flour and plastic and utilizing the solid cores cladded by the wood flour and plastic coating layers, and achieving the guarantees of integral structure strength of the doors and windows.

Description

technical field [0001] The invention relates to a corner structure of profile doors and windows, in particular to a corner structure of wood-plastic doors and windows. Background technique [0002] For a long time, the quality of the corner joints of doors and windows has played a very important role in the overall quality of doors and windows. Especially as the technology of using profiles to make doors and windows becomes popular, the joint strength of the corners of profile doors and windows plays a more important role in the overall quality and durability of doors and windows. The currently visible aluminum alloy doors and windows, aluminum-plastic doors and windows, PVC doors and windows, and wood-plastic doors and windows all have certain defects in the corner joints. Inadequate corner joints not only lead to a reduction in the service life of the doors and windows, but also lead to insufficient sealing of the doors and windows. And bring unnecessary heat consumption....

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned problems in the background technology, the purpose of the present invention is to provide a corner structure of wood-plastic doors and windows to solve the problems that the door and window profiles are easy to be damaged due to low connection strength and poor sealing performance. Good but high energy consumption, easy to deform due to the combined effect of thermal shrinkage and wet shrinkage of the material
