Aluminum-clad wood window, wood door and corner connecting structure for wood door and window

Abstract

The invention discloses a corner connecting structure for a wood door and window. The corner connecting structure comprises a first wood material and a second wood material, wherein a first inclined surface and at least one positioning plate are arranged on the end surface of one end of the first wood material, the first inclined surface is inclined relative to the cross section of the first wood material and is perpendicular to a plane formed by the axis of the first wood material and the axis of the second wood material, and the at least one positioning plate is parallel to the plane formed by the axis of the first wood material and the axis of the second wood material; a second inclined surface and a positioning surface are arranged on the end surface of one end of the second wood material, the second inclined surface is matched with and abuts against the first inclined surface, and the at least one positioning plate is matched with the positioning surface for positioning. With the adoption of the corner connecting structure, broken grain surfaces of the wood materials are combined through abutting and fixation of the inclined surfaces, the bonding strength is high, positioning is realized by the aid of the at least one positioning plate and the positioning surface, the connecting strength is further improved, the structure is simple, a composite surface positioning structure can still guarantee the strength of the connected surfaces under conditions of expansion caused by wetness and contraction caused by dryness, gaps do not appear easily, and the weather resistance is improved. The invention discloses the wood door and the aluminum-clad wood window which adopt the corner connecting structure.

Description

technical field [0001] The invention relates to the technical field of wooden doors and windows, in particular to a corner connection structure of wooden doors and windows. It also relates to a wooden door and an aluminum-clad wooden window using the angle connection structure. Background technique [0002] Wooden doors and windows mainly refer to solid wood doors and windows and aluminum-clad wood doors and windows, which have a long production history all over the world. At present, the mainstream products are European-style aluminum-clad wooden windows. The first material for doors and windows. However, the production process is complex and there are many quality assurance links. Among them, the angle connection of doors and windows is a key factor affecting the quality of wooden doors and windows. [0003] At present, there are mainly three types of corner connection structures on the market, namely, tenon-and-groove connection, bolt connection and 45° dovetail connect...

AI Technical Summary

Problems solved by technology

At the same time, this production process can only be painted, polished, and snap-fitted after the door and window frames are assembled, and the assembled door and window frames are large and heavy, so it is difficult to operate, the process is complicated, the equipment requirements are large, and the production cycle is long.

The bolted connection method can be used to produce a single piece of wood and assemble it after polishing and painting. The outer contour of the shape is positioned and spliced, and fixed by bolts. Due to the large number of positioning contact surfaces, it leads to over-positioning, and under the action of wood expansion and shrinkage, gaps are prone to appear at the reverse-shaped splicing; the other is a flat-headed round rod Tenon connection, that is, the butt joints of two pieces of wood that are relatively vertical butt joints are positioned by the plane and the round bar tenon perpendicular to the plane, and fixed by bolts. Positioning can prevent wood from moving in the joint plane, however, there will be gaps at the corner bevel joints due to expansion and contraction, resulting in water seepage, dust accumulation, and even fungal growth
