Abstract
A rigid structure is made up of two interengaging layers. One of the layers is of a generally corrugated form and has slots in the crests of the layer on one side. The second layer is made up of a series of laminae with slots in one side which fit into the slots in the first layer at an angle thereto and which lock the structure into a rigid unit.
Claims10
A rigid structure comprising a first layer of generally corrugated form and a second layer comprising a plurality of laminae arranged across the said corrugations of the first layer, slots being formed in one side of the corrugated form, the slots extending oppositely on opposite sides from crests of the form on the said one side of the first layer, similar slots formed in the laminae, the slots extending from a one edge of each laminae, the said slots in the laminae and the first layer being so disposed whereby the laminae can interengage with the first layer so as to enable the laminae to engage in the slots in the first layer to lock into the said slots of the corrugation form at an angle to the general plane of the structure.
