The heat-shielding panel (1) of the present disclosure includes a pair of sheets (10, 20) and an enclosed space (30). The pair of sheets (10, 20) are provided with an exposed surface respectively, and back faces of the pair of sheets (10, 20) are oppositely arranged at intervals. The pair of sheets (10, 20) are formed by heat-shielding sheets (12). The enclosed space is arranged between the pair of sheets (10, 20). The enclosed space is formed by sandwiching a spacer (31) between the pair of sheets (10, 20). A fluid such as air is enclosed in the enclosed space.

A torsion box panel assembly includes a plurality of sub-panels each having a skin secured to a core, and a plurality of hinges each coupled between a different pair of the sub-panels such that each sub-panel is foldable relative to an adjacent sub-panel along a respective hinge. The hingedly-coupled sub-panels together form a base panel having an expanded configuration in which each hinge is closed and the surfaces of the sub-panel skins are substantially co-planar. The base panel, in its expanded configuration, has a planar panel surface defined, at least in part, by the combination of the co-planar sub-panel skins. At least one stabilizing member is secured to the planar panel surface and spans all of the closed hinges to lock the sub-panels together to form a torsion box panel.

The present invention is directed to a multi-purpose panel member which may be utilized as any surface or support beam in a structure. In a preferred embodiment, the panel may be extruded monolithically from aluminum. Also disclosed are systems for assembling structures from the panels utilizing a plurality of other components, which are also preferably extruded from aluminum.

Structures including a curved corrugated wall fabricated from a plurality of layers formed of one or more shaped strips and methods of forming the structures are described. A shaped strip used in the fabrication includes a variable profile across the width of the strip with a first edge of a strip defining a series of cell profiles of a first geometric shape and a second, opposite edge of the strip defining a series of cell profiles of a second, different geometric shape, with each cell transitioning from the first profile to the second profile across the width of the strip. The geometry of the cell profiles at either end of each cell can be designed with respect to one another to allow for radial orientation of the strip about an axis with little or no deformation or stress on the strip edges.

For forming a sound absorption/insulation honeycomb panel by stacking an air-permeable material, a honeycomb material filled with a sound absorption material and a reflector, and adhesively joining these materials, it is hard to join the honeycomb material and the air-permeable material adhesively due to a thin wall surface of the honeycomb material and a resultant line to surface adhesive joint therebetween, causing a problem of low adhesive strength. By using a water absorption honeycomb material, an adhesive joint is formed with an adhesive joint area increased by dipping an end of a wall surface of a cell forming the water absorption honeycomb material into a water-soluble adhesive, making the end flexible over a fixed period of time, and then pressing the end strongly against an air-permeable material as a counterpart of the adhesive joint to deform a tip into an inverted T-shape.

There is provided herein a modular be fabricated wall system which has a number of interlocking modular prefabricated wall sections. Each wall section has opposing planar face boards and a number of orthogonal spacers adhered to respective inner faces of the face boards for bracing the face boards apart. Vertical joiners may be adhered to inner edges of each face board for quickly and easily vertically slotting together adjacent wall sections in a row. The present wall sections are low-cost in that both the face boards and the orthogonal spacers may be cut from low-cost board, such as fibre cement board. Specifically, the face boards and the spacers may be both made from fibre cement board and the spacers may be glued perpendicularly between inner surfaces of the face boards. As such, the present wall sections may be manufactured without fasteners, ties and the like.

A honeycomb for curved surface lightweight components includes a plurality of elongate ribbons and connecting regions. The connecting regions are provided, respectively, between opposing ribbons to connect the ribbons together in a portion-wise manner in a firmly bonded relationship in a transverse direction. The connecting regions are arranged at regular spacings along the longitudinal direction of a ribbon. Honeycomb-like cells form cavities between the ribbons. With respect to three successive ribbons, a displacement of the connecting regions between first and second ribbons relative to the connecting regions between second and third ribbons toward a first side of the longitudinal direction is lesser than toward a second side of the longitudinal direction. Consequently, at least a part of the cells in cross-section in the longitudinal direction/transverse direction plane have at least one longer limb corresponding to the greater displacement and at least one shorter limb corresponding to the lesser displacement.
