45 degree tenon joint board for wood door and window perpendicular connection angle

Abstract

The invention provides a 45-degree tenon connection board applied to the wooden door and window vertical connecting angle part, consisting of a section sheet corresponding to the 45-degree cross section of the wooden door and window vertical connecting angle part, connecting cylinder, a slot and a positioning heave, wherein, the connecting cylinder which is connected with a reserved cylindrical hole corresponding to the 45-degree cross section of the wooden door and window vertical connecting angle part is fixed on two surfaces of the section sheet vertically and symmetrically; the slot which corresponds to a reserved groove of the 45-degree cross section of the wooden door and window vertical connecting angle part is positioned on the section sheet, a dovetail joint for matching use is inserted into a dovetail groove formed by the reserved groove and the section sheet slot; and the section sheet is provided with the positioning heave for accurately positioning the groove on the 45-degree cross section of the window sash vertical connecting angle part. The 45-degree tenon connection board has the advantages that the connection is firm, so that the connection of door and window angle parts is more convenient; the 45-degree matching and the lateral surface of the wooden door and window 45-degree tenon connection board form decoration lines on the surface of the window and the door, thereby making the appearance of the window and the door more beautiful.

Description

(1) Technical field:

[0001] The invention relates to a connection structure applied to the vertical connection corners of wooden doors and windows, in particular to a 45° tenon connection plate applied to the vertical connection corners of wooden doors and windows. (two) background technology:

[0002] The wood corners of wooden doors and windows on the market now usually adopt the traditional 90° glued tongue-and-groove connection method. Insufficient tenon and tenon disengagement, glue opening and parallelogram deformation are caused, which are the problems to be solved by the present invention. (3) Contents of the invention:

[0003] The purpose of the present invention is to design a 45° tenon joint plate applied to the vertical joint corners of wooden doors and windows, which can overcome the above-mentioned shortcoming of the prior art, and has not only strengthened the connection strength of the corner joints of doors and windows, but also improved the assembly effi...
