Honeycomb composite board structure for container floor

Abstract

The invention discloses a honeycomb composite board structure for a container floor. The honeycomb composite board structure comprises a surface layer, a bottom layer, and a honeycomb core layer; wherein, the surface layer is bonding with the honeycomb core layer, and the bottom layer is bonding with the honeycomb core layer. The honeycomb core layer is made of sheet materials which are uniformly distributed with a plurality of through-holes with regular hexagon cross section. The regular hexagon through-holes form a honeycomb on the sheet materials. The side length of the regular hexagon is 2.5-3.5mm, and the wall thickness is 0.3-0.5mm. The wall thickness refers to the thickness of the common edge of two adjacent regular hexagon through holes. The thickness of the honeycomb core layer is 12-16mm. The composite board structure disclosed by the invention has the advantages of high stiffness and strength, and can meet the service conditions of the container floor. The honeycomb composite board structure is adopted by the container floor for saving wood and protecting environment, which solves the problem of lacking raw materials in the container floor industry.

Description

technical field [0001] The invention relates to a honeycomb composite board structure, in particular to a honeycomb composite board structure used for making a container floor. technical background [0002] With the development of the modern transportation industry, my country has become the largest producer of container flooring, and most of the raw materials for container flooring come from imports, most of which are unqualified and illegally imported logs. The sharp decline of hardwood resources such as Abitong (the main raw material of traditional container flooring) and the backwardness of flooring production technology have severely restricted the development of the container flooring industry, and its quality and availability have been declining in recent years. However, the current research on container flooring has made little progress. For example, CIMC's pine / birch hybrid wood flooring has been successfully applied to containers, but it has been suspended during t...

AI Technical Summary

Problems solved by technology

However, the current research on container flooring has made little progress. For example, CIMC's pine / birch hybrid flooring has been successfully applied to containers, but it has been suspended during the development process due to raw material procurement costs.

At present, only bamboo flooring is still in mass production. However, due to the large dispersion of mechanical properties of bamboo and wood flooring, and the defects of bamboo core are not easy to observe, it is a potential unsafe factor.
