The panels can be cast on-site, cured overnight, and immediately installed in the barrier formation. The panels are installed in a trench and the base portions are encased in concrete; the openings in the base allow the concrete to flow to both sides of the panel. Sensors, including cameras and vibration sensors, may be installed in the base section or in the foundation concrete or on the aboveground portion to detect actions on, over, or under the barrier.

Foam wall structures and methods for making them are described. The wall structures include a frame, a mesh mechanically fastened to a front surface of the frame, a foam panel at least partially abutting and overlying the mesh, and a foam layer disposed in a cavity defined by the frame, the mesh, and the foam panel. Buildings that include such wall structures are also described.

A folded building structure having a first roof portion, a second roof portion stacked on and pivotally connected to the first roof portion in a folded position, and a third roof portion stacked on and pivotally connected to the second roof portion in a folded position. The width of a transverse roof edge of the third roof portion is greater than the width of a transverse roof edge of the second roof portion and greater than the width of a transverse roof edge of the first roof portion.

A toe screw housing, for securing abutting enclosure components together, having a bearing plate with an interior face, an exterior face and a beveled upper edge; a toe screw well joined to and extending away from the interior face and including a fastener shelf; a toe screw support joined to the interior face, and additionally joined to and extending away from the fastener shelf, the toe screw support distal from the fastener shelf including a planar support surface oriented perpendicular to the interior face; and a fastener bore passing through the fastener shelf, the toe screw support and the support surface and inclined at a second angle relative to the interior face of the bearing plate.

Modular building methods and systems using precision machined modular panels. Standard modular panels are used for constructing walls, floor, and roof, with transitions from wall to roof and wall to floor provided by special transition panels. The standard panels include a channel formed configured to receive a flange of a C-channel member. The present method progresses by installation of a foam panel (or stack or row of such panels), followed by installation of a C-channel member, with the flange of such member engaged in the panels, followed by installation of an adjacent row or stack of panels, before installation of the next, adjacent C-channel member. Such alternating placement of panels and frame members eliminates the need for a tape measure, the need for any independent frame for the building, and ensures the walls, floor, and roof are square and plumb, as the precision machined panels ensure these requirements are met.

A precast concrete panel and method for forming the panel are disclosed. A method of forming the panel to be used as a floor, wall, or roof structure includes positioning one or more forming members within a casting bed having a plurality of upright surfaces defining a generally rectangular interior area, the one or more forming members comprising an insulating material extending along a length dimension of the one or more forming members to define a plurality of rectangular-shaped channels in a parallel and spaced-apart relationship, placing uncured concrete within the casting bed and allowing the concrete to cover the one or more forming members and substantially fill the channels, and allowing the concrete to cure.

A building apparatus for a residential or commercial building that includes a prefabricated wall panel and a horizontal beam mounted on a top of the prefabricated wall panel. The prefabricated wall panel includes a first concrete block, a second concrete block, and an insulation panel sandwiched between the two concrete blocks. A plurality of spaced-apart hollow tubes extend between the top side and the bottom side of the prefabricated wall panel and each tube has a flange at its a periphery. The tubes reinforce the first concrete block, and the flanges are supported on the top side of the wall. The horizontal beam is fastened to these flanges. The prefabricated wall panel further includes a U-shape beam that extends from the top side to the bottom side and is positioned at or near the left side or the right side of the prefabricated wall panel. A plurality of slings spaced apart run along a length of the U-shape beam and can provide for assembling two wall panels.

A fabrication facility for manufacturing a laminate multi-layer enclosure component having a press table; a conveyor table adapted to move a plurality of superposed planar fabrication elements of a multi-layer enclosure component placed thereon into the press table; a first rotatable turntable proximate to a first side of the conveyor table, and a second rotatable turntable proximate to an opposed second side of the conveyor table. The first rotatable turntable is adapted to have positioned thereon plural stacks of planar fabrication elements and to move each of such plural stacks to a first access position on the first rotatable turntable; and the second rotatable turntable adapted to have positioned thereon plural stacks of planar fabrication elements and to move each of such plural stacks to a second access position on the second rotatable turntable. A movable adhesive spray gantry straddles the conveyor table.

A wall panel includes a first and second planar skins and a core disposed therebetween. A first and second lateral edge extends between the skins. The second lateral edge comprises a female receiver. The first lateral edge comprises a male extension extending therefrom. The female receiver is formed in the core and has a depth equal to or greater than a length of the male extension. The male extension is formed from the core comprises a first parallel surface extending parallel to and offset from the first planar skin and a second parallel surface extending parallel to and offset from the second planar skin. A first tapered portion comprises a first tapered surface extending at an angle relative to a longitudinal axis from the first parallel surface to a rounded end, and a second tapered surface extending at the angle from the second parallel surface to the rounded end.
