Embodiments of the invention relate to structural panel systems, and in particular in-frame fluted panel systems. The in-frame fluted panel systems allow for improved strength and/or ductility within a reduced wall thickness by installing the fluted panels within the framing of the support members in various configurations. The in-frame fluted panel systems further allows for easier construction and lower costs than conventional systems that have fluted panels located outside of the support members.

A wall/roof panel includes (a) a façade that has (i) an outer surface that defines a front surface of the panel and (ii) a rear surface and (b) a structural element connected to and supporting the façade.

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.

Methods for constructing a building module which is a sandwich panel comprising a first region which provides part of the roof structure of a building, a second region which provides part of the wall structure of building, and a third region which provides part of the floor structure of the building.

A building module which is a sandwich panel comprising a first region which provides part of the roof structure of a building, a second region which provides part of the wall structure of the building, and a third region which provides part of the floor structure of the building.

Sheet-like composite parts are manufactured by: a) providing a substantially planar arrangement (A, B, A′) comprising a core layer (B) comprising a a fleece material made of fleece thermoplastic fibers and reinforcement fibers, sandwiched between a pair of skin layers (A, A′), each comprising a skin thermoplastic and optionally reinforcement fibers, one face of the core layer being adjacent and substantially parallel to a skin layer and a second face of the core layer being adjacent and substantially parallel to the other skin layer, b) heating and pressing the sandwich arrangement (A,B,A′) followed by cooling, thereby obtaining the composite part, wherein the compression strength of the composite part is improved with a core layer (B) which is a Z-oriented core layer having reinforcement fibers that are predominantly oriented in a direction (Z) perpendicular to the first and second faces, produced by multiple folding.

A modular shelter structure is an apparatus that provides readily available housing for a variety of environments. The apparatus includes a shelter, a plurality of first locking mechanisms, and a plurality of second locking mechanisms. The shelter includes a floor base, a plurality of portable walls, and at least one roof panel. The floor base balances the shelter across various terrains. The plurality of portable walls surrounds the floor base and defines an interior environment with the floor base. The interior environment is enclosed with the at least one roof panel. The plurality of portable walls is attached onto the floor base with the plurality of first locking mechanisms. Similarly, the plurality of portable walls is attached onto the roof panel with the plurality of second locking mechanisms. The plurality of first locking mechanisms and the plurality of second locking mechanisms each include an inner tube and an outer sleeve.

An example plasterboard includes a layer of hardened plaster material having a first surface and an opposed second surface and a layer of molded material having a surface that faces away from the layer of hardened plaster material. The surface of the layer of molded material has one or more raised features. The plasterboard also includes a liner between the first surface of the layer of hardened plaster material and the layer of molded material. Other examples include a method of forming such plasterboards and a method for installing such plasterboards.

Structural dovetail decking panel systems that utilize dovetail decking panels with a proximal edge having a proximal arm extending outwardly away from the dovetail decking panel, and a distal edge having a distal arm extending inwardly towards the dovetail decking panel. When adjacent dovetail decking panels are joined, the proximal edge having the proximal arm of a panel is placed over the distal end having the distal arm of the adjacent panel to create a dovetail sidelap. The proximal arm and/or the distal arm aid in restricting movement of the proximal edge and the distal edge of adjacent panels in order control the dimensions of a sidelap cavity and opening in the dovetail sidelap, which improves the strength of the dovetail decking panel systems, allows for the reduction of the thickness of the panels or number of couplings used, and/or allows for anchors to be utilized within the sidelap cavity.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.
