Description

Technical Field

[0001] The utility model relates to the technical field related to plywood, in particular to a plywood structure with stable connection. Background Art

[0002] Plywood is one of the commonly used materials for furniture. It is a kind of man-made board. A group of veneers are usually assembled and glued together in the direction of the wood grain of adjacent layers at right angles to each other. Usually, the surface board and the inner layer board are symmetrically arranged on both sides of the center layer or the core. The slabs are made by staggering the veneers coated with glue in the direction of the wood grain. They are pressed under heating or unheating conditions. The number of layers is generally odd, and a few have even numbers. The physical and mechanical properties in the vertical and horizontal directions are slightly different. Commonly used are three-ply board and five-ply board. Plywood can improve the utilization rate of wood and is a major way to save wood. It can also be used as material for airplanes, ships, trains, cars, buildings and packaging boxes.

[0003] During the installation process of plywood, two plywood boards are mostly spliced ​​together using glue and slots. Glue adhesion can easily cause formaldehyde to exceed the standard, which is harmful to the human body. After the slots are spliced ​​for a long time, the joints are prone to loosening or large gaps will appear, affecting the splicing and use of the plywood. Utility Model Content
