The present invention is directed to an improved gypsum board, such as an improved sound damping gypsum board. The gypsum board comprises a gypsum core including gypsum and a sound damping polymer. The gypsum core includes a first gypsum layer surface and a second gypsum layer surface opposing the first gypsum layer surface. In addition, a first encasing layer is disposed on the first gypsum layer surface and a second encasing layer is disposed on the second gypsum layer surface.

Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.

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.

An article of manufacture is disclosed comprising a 3D-printed wall panel having an interior side and an exterior side. The exterior side comprises a textured surface formed by 3D printing the wall panel onto a textured form. In certain embodiments, the textured surface mimics at least one of natural stone, brick, and wood siding, and the medium printed onto the textured form is concrete. The interior side has 3D printed structural elements printed thereon designed to mimic conventional wood-stud framing in at least one of dimensions and spacing. A method for fabricating the 3D printed wall panel as described above is also disclosed.

Disclosed embodiments include the production of construction plans upon planar surfaces such as studless walls near studless walls or traditional framing. Disclosed embodiments include specialized databases, cutting systems and printing systems useful for implementation of various plans upon planar surfaces sometimes used with hollow wall systems, sometimes constructed with bamboo or other fast growing sources of structural fiber, with the types of subject printing and cutting sometimes including architectural plans, structural plans, electrical plans, plumbing plans, mechanical plans, insulation plans, media plans, security plans and construction plans and details including those derived directly from various plans.

Described herein is a barrier coating composition comprising an organic blend comprising a first component and a second component, the first component comprising latex polymer and the second component being selected from polyurethane emulsion, wax emulsion, and alkyd emulsion, wherein the first component and the second component are present in a weight ratio ranging from about 2:1 to about 20:1, and the latex polymer has a glass transition temperature of less than about 18° C.

A cross-laminated timber panel comprises a plurality of layers of lumber boards, each layer comprising a number of the lumber boards laid side-to-side pointing to a direction, each layer being disposed perpendicular to the direction of an adjoining layer; and an insert member replacing one of the lumber boards, the insert member having a different material or configuration than the lumber boards.

A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.

A modular foundation system comprises a concrete reinforced matrix having embedded pre-tensioned components and a recessed tension bolster region adjacent the lower surface of the foundation at each end, and a pair of lifting safety bars partially embedded in the foundation within the recess and terminating at the end of the foundation.

A modular device adapted for subdividing room space, the modular device comprising: a panel comprising a corrugated portion positioned between a first planar surface and a second planar surface of the panel, wherein the peaks of the corrugated portion are in engagement with the first planar surface, wherein the troughs of the corrugated portion are in engagement with the second planar surface; the first planar surface and the second planar surface each having a first end and a second end; wherein the first and second ends of the first planar surface are respectively opposite relatively to the first and second ends of the second planar surface; the second planar surface is parallel to the first planar surface; wherein the corrugations are is parallel to the vertical axis of the panel; a concave female portion positioned along the vertical axis in the panel, wherein the concave female portion is formed from at least: the first end of the first planar surface, the first end of the second planar surface, and a curved portion from the corrugated portion; a convex male portion positioned along the vertical axis of the panel, wherein the convex male portion is positioned outside of the second end of the first planar surface and the second end of the second planar surface; wherein to extend the length of the panel, the convex male portion of a first panel is adapted to engage with the concave female portion of a second panel.
