Problems solved by technology

Oriented structural panels cannot be used alone for the bottom of containers because their mechanical performance parameters such as longitudinal static bending strength, transverse static bending strength, longitudinal elastic modulus, and transverse elastic modulus do not meet the requirements of container bottom plates.

Abstract

The invention relates to an oriented structural board for a container soleplate. The oriented structural board adopts the oriented pavement in at least three layers, the oriented pavement adopts longitudinal pavement layers and transverse pavement layers, which are paved alternately, the upper surface layer and the lower surface layer of the oriented structural board are longitudinal pavement layers, and the mass ratio of the longitudinal pavement layers to the transverse pavement layers is (50-70):(50-30). The oriented structural board has superior mechanical property and can be independently used for the soleplate of the container.

Description

technical field [0001] The invention relates to a container, in particular to an oriented structural plate for the bottom plate of the container. Background technique [0002] The container is composed of steel plate, paint and the bottom plate as a shock absorber - thick plywood. Since the container floor is mainly used in the transportation process, it must have good performances such as shock resistance, impact resistance, weather resistance, and aging resistance. Therefore, in addition to the appearance size, high requirements are placed on the physical properties of the plywood used for the container floor such as the durability of the glue, the static bending strength, and the modulus of elasticity. In order to meet the requirements of product physical performance indicators, high-density hard broad-leaved wood is generally used as raw material for the wooden floor of the container. Due to the long growth period of this kind of tree species, generally about 100 years...
