Abstract: The present invention relates to vacuum insulated building panels. The insulating building panel of this invention uses suction pressure created by a vacuum as the sole means of attachments between two parallel steel (10) or glass (12) panel plates and a post frame (14). When vacuum is applied, the plates engage the post frame in an airtight manner and spheres (112) are used as spacers to maintain separation of the plates and they roll without resistance to accommodate any movement of one plate in relation to the other. These features of the building panel eliminate warping which is caused by expansion or contraction of weather exposed faces of the panel plates due to fluctuating outside temperatures and also eliminate stress upon support structures.

Abstract: A tough, water-proof building panel, made of fiber-reinforced polymer, is useful in making structural walls, ceilings, and floors of buildings. Upstanding such walls can have vertical and horizontal strengths sufficient to be used in place of concrete, as an engineered solution, both above grade and below-grade, including in severe weather conditions. Panels effectively have inner and outer layers, and structurally reinforcing members. Structurally-reinforcing members extend, typically as layer and/or stud, the full height of the wall panel, at spaced locations along the length of the panel. Spaces between the structurally reinforcing members are optionally filled with rigid thermally insulating foam. Optional reinforcing studs are attached to, or overlaid by, the inner layer, and extend inwardly into the building from what is otherwise the inner surface of the building panel. Panels can be made by e.g. assembling pre-fabricated blocks and/or webs, by evacuating a mold, and by pultrusion.

Abstract: A collapsible cellular insulation panel for use with mobile shelters is provided. The panel comprises first and second outer sheets with a plurality of intermediate thin flexible membranes. The membranes are secured along first and second edges to inner surfaces of the outer sheets. The membranes are attached to adjacent membranes along strips that are parallel to and intermediate the first and second membrane edges. The interconnected membranes form cells that trap insulating air and break up convective currents between the outer sheets. Supported from underneath on a horizontal surface, the membranes lay substantially flat, such that a thickness of the panel substantially equals the sum of the thicknesses of the membranes and outer sheets. The panel is thus well adapted for use with mobile shelters, because it occupies little volume in the collapsed state.

Abstract: The fundamental technique of the method for making cellular cores is to make stacks of components which are configured such that cutting slices off the stacks produces cellular cores and, when needed, components used in stacks used to produce cellular cores. One of the basic components used in the stacks is termed a ribbed ply which is a ply (thin sheet of material such as wood) with a number of ribs (long thin strips of material such as wood) attached to the ply, parallel to each other. The spaces between the ribs are filled with filler material such as foam plastic, and the cells in the cellular core are filled with the filler material. The filler material is introduced as layers of the material stacked alternately with plies and adhesively attached. Slices of such a stack, sliced parallel to the grain of the plies (if wood) are called ribbed fillers. Stacking ribbed fillers and plies produces a stack having a cross section which, when sliced, produces filled cell cellular cores.

Abstract: A construction element 1 consists of multiple individual layers 2, 3, 4 whereas the medium layer 3 is in turn composed of a multitude of additional individual layers 23, 24, 25. The individual layers 2, 4, 23, 24, 25 are configured in such a way that they interlock and clamp into each other thereby producing or defining surfaces that allow the elements or individual layers 2, 4, 23, 24, 25 that are integrated in the construction of the construction element to evenly absorb the forces that are being applied. At the same time, not only pressure or lateral forces but also tensile and transverse forces can be absorbed so that altogether a construction element 1 with a low weight but high stability has been created. This construction element 1 can be shaped or deformed appropriately and can also be extended three-dimensionally so that an adaptation to the individual conditions in any plane or direction is possible.

Abstract: A composite panel waffle stiffener has fabric plies pre-cut to a selected pattern and laid on a tool having a waffle configuration. The plies overlap each other to maintain continuity of the structure. The resulting waffle stiffener is then bonded to a panel requiring stiffening. The stiffener is flexible and may be bonded to curved panels. Holes in the stiffener allow access to the volume between the stiffener and the panel for minimizing volume loss within, for example, a wing structure containing fuel and for ventilating air or moisture trapped in the volume.

Abstract: A top sheet and a bottom sheet are connected together by wing members, each having a center segment hinged to the top sheet and to the bottom sheet about parallel axes. Wings protrudes from the center segments and are biased to project out of a plane defined between the hinge axes. In a collapsed condition the top and bottom sheets are close together with the wings distorted from their relaxed positions. In the expanded condition the sheets are spaced apart and the wings return to their relaxed positions projecting out from the center segments and conferring stiffness on the structural member and resisting the return of the member to its collapsed configuration. In storage, the sheets are secured along the edges with an underlying rip cord, and may be rolled. The wings may be formed as part of metal or plastic spring members.
