Container floor apparatus using wood polymer composite

摘要

A container floor apparatus using wood polymer composite includes traverse supports continuously disposed to longitudinal frames at a predetermined interval, the longitudinal frames being longitudinally connected to vertical columns at four corners of the container. The longitudinal supports have a single central rail formed at upper portions of the traverse supports between the traverse frames and two side rails formed both sides of the central rail disposed parallel to and between the central rail and the longitudinal frames and further provided with a downwardly extending reinforcement piece. Convex floor members are made from wood polymer composite containing a cured mixture of about 30-50% of synthetic resin, about 50-70% of wood flour and chaff or pulp and about 2-10% of a binder. Gaskets surround each side surface portion of the floor members. Fixing means couple the floor members to the traverse supports in the block mounting spaces.

1. A floor apparatus having a wood polymer composite for use in a stackable, rectangular box cargo container comprising:
traverse supports disposed between two longitudinal frames at a predetermined interval, wherein end portions of the longitudinal frames are connected to columns which are vertically mounted at four corners of the cargo container; longitudinal supports having a single central rail disposed on upper portions of the traverse supports, in which the central rail has a horizontal bottom surface extending in a longitudinal direction and vertical side surfaces extending in the longitudinal direction, wherein the bottom surface and side surfaces form a downwardly opening box configuration in the center and horizontal base portions extend outwardly from a lower edge of the side surfaces, and two side rails at both sides of the central rail disposed parallel to and between the central rail and the longitudinal frames, in which the side rails have a horizontal bottom surface extending in the longitudinal direction and vertical side surfaces extending in the longitudinal direction, wherein the bottom surface and side surfaces form a downwardly opening box configuration in the center and a vertical reinforcement piece is further provided that extends downwardly from the bottom surface; floor members made from the wood polymer composite, wherein the wood polymer composite comprises a cured mixture of about 30-50% of synthetic resin, about 50-70% of wood flour and chaff or pulp and about 2-10% of a binder, and wherein the floor members are disposed in spaces between the traverse supports and the longitudinal supports; the floor members have side surface portions; gaskets surrounding each side surface portion of the floor members; and fasteners that couple the floor members to the traverse supports.
