Description

Technical Field

[0001] The utility model relates to the technical field of plywood, in particular to a splicing structure for installing composite plywood. Background Art

[0002] Plywood is one of the commonly used materials for furniture and is a kind of artificial board. Plywood is made by slicing wood segments into veneers or planing wooden squares into thin woods, and then gluing them with adhesives to form a three-layer or multi-layer board-like material. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are perpendicular to each other. Its surface board and inner layer board are symmetrically arranged on both sides of the central layer or board core. The shape of the board product is flat, with a large aspect ratio, and the surface area per unit volume is also very large. This shape feature has a large surface area, so the containment and coverage ability is strong, and it is widely used in chemical industry, containers, construction, metal products, metal structures, etc.;
