REINFORCED INTERMODAL CONTAINER

摘要

A reinforced intermodal container has a corrugated steel wall with an outer side and an inner side. In a length direction the corrugations have alternating inboard and outboard flat panels with adjacent panels linked by web portions. A strengthening structure is welded to the container wall which provides flanges extending generally perpendicularly to the general plane of the wall. The flanges extend between plates welded to the inside faces of the outboard panels and flat strengthening plates welded to the inside faces of the inboard panels. The strengthening structure does not alter the outside width of the container in comparison with the outside width of the unreinforced container. The strengthening structure reduces the inside volume of the container by only a small amount compared with the volume of the unreinforced container.

1. A method of reinforcing an intermodal container corrugated steel wall, the wall having an outer side and an inner side, the corrugations in a container length direction having alternating inboard and outboard flat panels extending parallel to the general plane of the wall and with adjacent panels joined by web portions, the method comprising positioning a first plate flat against the interior of an outboard panel and welding the first plate to the first outboard panel, positioning a second plate flat against the interior face of said next adjacent inboard panel and welding the second plate to said next adjacent inboard panel, at least one of the first and second plates having an integral web member extending substantially perpendicularly to the general plane of the container wall, and welding the integral web member to the other of the first and second plates.
