The present invention provides a sandwich panel and a sandwich panel structure formed by welding a plurality of the sandwich panels, each sandwich panel comprising: a flocking core layer; and skin layers laminated on both surfaces of the flocking core layer, respectively, wherein the sandwich panel comprises at least one contact portion, at which the two skin layers abut each other. In addition, the present disclosure provides a method for manufacturing a sandwich panel, the method comprising the steps of: preparing a sandwich panel comprising a flocking core layer and skin layers laminated on both surfaces of the flocking core layer, respectively; and applying heat and pressure to at least one surface of the skin layers, thereby forming at least one contact portion.

A double wall panel member for use in a panel wall is provided which includes a tongue-configured end and a groove-configured end. The panel member includes a first outer wall spaced laterally from a second outer wall, and the groove-configured end has a first groove wall portion extending from the first outer wall and a second groove wall portion extending from the second outer wall, where the first groove wall portion extends further outward than the second groove wall portion. When connected, the wall panel members are assembled with the groove end pointing or oriented upward (not downward) and the tongue end pointing or oriented downward (not upward).

A load bearing building panel having a first sheet intended to provide an inner building surface, a second sheet intended to provide an outer building surface, and an insulating foam core sandwiched between them. The sheet that provides the inner building surface is corrugated to define co-planar portions separated by a plurality of channels which are dimensioned so as to be able to accommodate standard size electrical boxes and/or plumbing pipes. Advantageously, the other sheet is also corrugated to define a plurality of channels so that a plurality of panels can be stacked in a partially nesting relationship.

A building formwork component comprising first and second spaced sidewalls having one or more webs extending there-between, each sidewall comprising a flange extending inwardly along a first edge of the sidewall such that an outer surface of the flange forms a ramp surface; and a groove extending along an opposing second edge of the sidewall; wherein the component may be coupled to a like component by relative movement of the components towards each other, whereby the flanges are received in respective grooves of the like component, and whereby the ramp surfaces facilitate such coupling by engaging respective second edges of the like component to move the second edges and/or ramp surfaces for engagement of the flanges in the grooves.

A panel (6) is disclosed for use in construction. The panel (6) comprises opposing surfaces (6A, 6B) that extend between first and second opposite ends (7A, 7B). The panel (6) also comprises a plurality of parallel (e.g. sawtooth) ridges (7). The ridges (7) are provided on at least one of the opposing surfaces (6A and/or 6B). The ridges (7) extend along and adjacent to a first of the opposite ends (7A or 7B) of the panel for at least a part length thereof. The ridges (7) are arranged to engage with and move past corresponding ridges of an adjacent panel (6) when the panels move relative to each other in opposite directions. The ridges (7) are further arranged so as to interfere with the ridges of the adjacent panel to resist relative movement in a reverse of the opposite direction.

A residential or commercial building, structure, or building component can include an exterior member, interior member, and plurality of cross-members spatially disposed therebetween. Each of the exterior member, interior member, cross-members can be formed from a multi-layered stack of polymeric material made by a layered three-dimensional printing process, and all can be monolithically integrated. An exterior surface region of the exterior member can have an integrally formed surface finish. Overlying finishing or connective layers can be added. The exterior and interior members can be configured in a parallel arrangement to form a rectangular or curve shaped building block. A fill material can be disposed into openings between the exterior and interior members, and an interior surface region at the interior member can include a cavity configured for an electrical box, plumbing, or a sensing device.
