Composite bottom board for container

Abstract

The invention discloses a composite bottom board for a container, which is formed by stacking and gluing a plurality of veneers; and the composite bottom board comprises an upper surface layer, a lower surface layer and a middle layer sandwiched between the upper surface layer and the lower surface layer. Through reasonable structural design, on the promise of ensuring that the performance of the bottom board can meet the usage requirement of the container, the log resources are better utilized so as to obtain high-quality face / bottom boards; and the laying-up mode of the traditional bottom boards for the container is changed, current log resources are more effectively utilized, the contradiction between the supply and requirement of the log resources is relieved, and the manufacturing cost of the bottom board for the container is reduced.

Description

technical field

[0001] The invention relates to a composite bottom plate, in particular to a composite bottom plate for a container. Background technique

[0002] For a long time, the panel of the container floor has been using the long middle plate, that is, the veneer parallel to the longitudinal direction of the panel texture container chassis. The longitudinal strength of the container is greater than the transverse strength, so in the traditional container floor structure, there are mainly 3×3 or 3×2 structures, the main purpose of which is to place the long middle plate along the grain on the outermost side of the floor to strengthen the longitudinal direction of the floor strength. When the log is rotary cut into wood veneer, the length direction of the log is the direction along the grain of the wood veneer, and the shorter the length of the log, the lower the resistance of rotary cutting and the relatively higher overall rate of the veneer. Therefore, in daily prod...
