Disclosed herein are plaster boards having a first surface and an opposing second surface, and a first edge and an opposing second edge that bound the first surface and the second surface. The first surface includes a first section and a second section, the first section being raised compared to the second section, the second section abutting the second edge. The second surface includes a first section and a second section that are separated by a boundary between the first edge and the second edge. The first section of the second surface is substantially parallel to the first section of the first surface. The second section of the second surface slopes toward the first surface from the boundary toward the second edge. Methods for making the plaster boards involve forming wet plaster material and drying the wet plaster material such that the wet plaster material hardens into a plasterboard.

A structural insulation panel (SIP) is made of a central insulation material or block core covered with cementitious material. The layers of cementitious material are reinforced with fiber mesh sheets, rebar and corner blocks. The corner blocks are held in thickened cementitious material edges by reinforcement pins that are fixed to the corner blocks. The corner blocks are accessible for lifting the panel and for assembling multiple panels to build a wall.

A construction panel contains at least one insulation layer, at least one active thermal layer containing at least an electrical heating and/or an electrical cooling element, and a connector for connecting the at least one active thermal layer to a source of electrical current. The active thermal layer is preferably an active heating or cooling layer.

A composite structure joining system and method comprises a structural panel, preferably but not necessarily fabricated from structural composite materials, that further comprises a nesting C-joint feature that facilitates assembly of a plurality of panels of the invention to form a planar structure such as a wall. An embodiment of the present invention comprises a plurality of the panels of the invention, joined together using the C joint of the invention, captured in a frame. The frame structural elements may comprise metals such as aluminum or steel, or may be hand laid or extruded fiberglass as described in more detail below. The invention further comprises methods of manufacturing a plurality of structural panels of the invention. The method of the invention may be used to fabricate intermodal shipping containers that have superior structural and thermal characteristics, are lightweight, resulting in lower transportation costs and lower container costs.

In accordance with an example embodiment, there is disclosed herein, a panel that comprises a plurality of ornamental sections having a predefined shape, the plurality of ornamental sections are arranged in rows that form a staggered arrangement with protruding rows and recessed rows between the protruding rows along at least one edge of the panel. A plurality of interior grooves are located between the ornamental sections, the interior grooves having a first width. A plurality of partial grooves having a second width are located along the at least one edge of the panel. Ornamental sections at an edge of a protruding row comprise convex curves having a first radius at their edges. Ornamental sections at the edge of recessed rows comprise concave curves having a second radius at their edges.

This document a method for forming a surface of an interior wall or a ceiling. The method comprises providing a pair of building boards (S1, S2), attaching by means of nails (3) the first building board (S1) to a stud (2), joining the edge portion (1′) of the second building board (S2) with the edge portion (1) of the first building board, so that the tongue (101) of the first building board extends into the groove (102) of the second building board, attaching by means of nails (3) the second building board (S2) to the stud (2), and gluing a surface covering fabric (4) directly to an exposed main surface (11, 12) of the building boards (S1, S2), such that the surface covering fabric covers the building boards (S1, S2). The document discloses a method for manufacturing a prefabricated building element, a structure comprising a pair of building boards, and a way of manufacturing a building board.

In some implementations, a conductive concrete composition for providing improved shielding against electromagnetic radiation comprises cement, one or more supplementary materials, aggregates, one or more carbon products, and fibers. In some implementations, the composition comprises between about 5% and about 40% by weight of cement, between about 1% and about 20% by weight of one or more supplementary materials, between about 5% and about 80% by weight of aggregates, between about 1% and about 40% by weight of one or more carbon products, and between about 1% and about 10% by weight of fibers. In some embodiments, the one or more supplementary materials comprises ground granulated blast furnace slag (GGBS), the one or more carbon products comprises graphite, and the fibers comprise steel fibers. The aggregates can include normal weight, lightweight, and/or fine aggregates.

A construction system utilizes a post-and-beam structure that supports major gravity loads of a building in combination with prefabricated exterior and/or interior wall panels that are not required to support gravity loads beyond self-weight. Studs within the prefabricated wall panels are oriented such that a widest face thereof is other than normal to the wall surfaces attached thereto. Such an orientation of the wall studs reduces or eliminates thermal bridging in the structure without adding materials, thereby reducing embodied carbon and embodied energy content. The orientation of the wall studs also maximizes the available space within the wall panels to accommodate electrical and plumbing utilities and insulation material and utilizes the studs along their strong axis to resist lateral loads.

The invention relates to a panel and a method for producing a panel. The panel is in particular a floor, wall or ceiling panel, and comprises at least one core layer, the core layer comprising an upper core surface and a lower core surface and at least one pair of opposite side edges; wherein the core layer comprises magnesium oxide cement; wherein the core has a density which is substantially homogenous over its entire volume, and wherein at least one decorative top layer is attached to an upper core surface of the core layer.

Systems and methods are described herein for a panelized building assembly. In one example, an assembly may include one or more of a first composite planar panel, and second composite planar panel, and a planar joining element. The first and second planar panels may include a core material sandwiched between two fiber-reinforced skin elements. Each of the panels may include a first block of fiber-reinforced material coupled to at least one of the skin elements, which may define two slots for receiving the planar joining element. In some cases, the planar joining element, when placed within the slots of two panels to be joined, may transfer a load between the fiber-reinforced material of the two panels. The resulting joint may form a water-tight and fire-retardant seal.
