Abstract
A multiply corrugated paper wall construction having increased resistance to bowing or flexing under loads applied in a plane normal to the plane of the wall. The construction includes the provision of one or more rigid reinforcing members of elongated non-planar cross section implanted and glued into corresponding recesses in at least one of a plurality of laminae comprising the construction. In a preferred embodiment, the reinforcing member is of 'T' shaped cross section with the leg of the 'T' lying in a plane normal to the plane of the wall. A second embodiment, useful where greater strength is required, includes a reinforcing member having a 'W' shaped cross section.
