Abstract
A hollow structural component suitable for an aircraft structure includes an inner framework of intersecting longitudinal and transverse ribs, cover sheets covering the top and bottom of the framework, and end closure sheets covering ends of the framework. The transverse ribs have slots to receive the intersecting longitudinal ribs and vice versa, so the ribs intermesh in a grid pattern. Top and bottom edges of the ribs have protruding connector tabs that are fitted into slots provided in the cover sheets. Additional connector tabs at the ends of the transverse ribs are fitted into slots in the end closure sheets. After the parts are assembled by intermeshing the longitudinal and transverse ribs and fitting the connector tabs of the ribs into the slots of the cover sheets and end closure sheets, the resulting plugged-in joints are permanently mechanically secured, e.g. by welding, brazing, soldering or adhesive bonding.
