Spliced plywood

Abstract

The invention relates to a spliced plywood, and belongs to the technical field of plywoods. A plywood base plate is arranged between two outer layer plates, and comprises multiple groups of core veneers; at least two groups of core veneers are arranged; in addition, each two adjacent core veneers are connected through the mutual engagement of a first connecting part and a second connecting part matched mutually, so that the connecting stability of the spliced plywood is improved, the overall structure strength of the spliced plywood is improved, and the occurrence of the phenomenon that panelsare cracked is prevented; meanwhile, a groove and a convex strip matched mutually are arranged on the combined part of the first connecting part and the second connecting part, so that the core veneers can be prevented from sliding relatively so as to be misplaced due to the mutual cooperation of the convex strip and the groove, and the connecting strength of the spliced plywood is further improved; and a dampproof layer and a fireproof layer are arranged between the outer layer plates and the plywood base plate, so that dampproof performance and waterproof performance of the spliced plywoodare improved, and the service life of the spliced plywood can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of plywood, in particular to a spliced ​​plywood. Background technique [0002] As we all know, plywood is a three-layer or multi-layer board material made of wood segments that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers are The fiber directions of the veneers are glued together perpendicular to each other. Plywood is one of the commonly used materials for furniture, and it is one of the three major man-made boards. The commonly used types of plywood include three-plywood and five-plywood. A main way, but the plywood at the current stage is found to have insufficient bonding strength during use, and cracking of the board often occurs. SUMMARY OF THE INVENTION [0003] In view of the problems in the background, the object of the present invention is to provide a spliced ​​plywood. [0004] In order to achie...
