A multi-layered integrated roofing plank or panel with a base layer comprising engineered or manufactured wood, a water resistant barrier layer covering at least the outer face of the base layer, and at least one of the edges of the base layer. A silicone layer may cover at least a portion of the outer face. The silicone layer may be embossed with a pattern. A texturizing material also may be affixed to, or integrated with, the water resistant barrier layer. The edges of the roofing plank or panel may be configured as part of a joint with adjacent planks or panels, including, but not limited to, shiplap joints, tongue-and-groove joints, bead-and-cove joints, butt joints, or combinations or variations thereof.

This technology comprises a combined accessory of an in-situ concrete 3-D printed horizontal load-bearing member and a preparation method. The combined accessory includes 3-D printed concrete and a bottom mesh, the 3-D printed concrete contains fine aggregates having the particle size of 0.08 mm-4.75 mm, and the fluidity of the 3-D printed concrete is larger than or equal to 110 mm and smaller than or equal to 190 mm; the bottom mesh is a reinforcing mesh or expanded metal, the diameter of the reinforcing bar is larger than or equal to 0.5 mm, and the mesh aperture of the reinforcing mesh is smaller than or equal to 7.5 times of an upper limit of the particle size of the fine aggregate and is larger than or equal to 7.5 times of a lower limit of the particle size of the fine aggregate.

A plurality of wall cells rest upon an underlying cementitious foundation and form a perimeter of the vault. Each wall cell has two lateral sides with mating surfaces thereon which are of complementary undulating shape with adjacent lateral surfaces of adjacent wall cells. The wall cells have different thicknesses and widths to provide desirable wall thickness for a different portions of the oncology vault. A door assembly formed of specialized wall cells and with a pivoting door element are also included within the wall. A ceiling is provided above space inboard of the wall cells. This ceiling is formed of separate ceiling slab elements. The slabs are stacked in at least one layer. In one embodiment, multiple layers of slabs are stacked with seams between slabs of each layer offset from each other. In another embodiment, lateral sides of the slabs have a complementary undulating shape.

An interlocking system of modular units engageable to form vertically and horizontally stable assemblies. The modular units include blocks and modular panels, each having vertical and optional horizontal bores that provide passage for plumbing, electrical wiring, and other connectivity. The modular units may be formed of lightweight cementitious materials, and may find use in assemblies such as walls, floors, ceilings, roofs, and entire building structures.

A system for creating an enclosed room, such as an office, in an open space that has a floor and a ceiling. The system includes a support frame that is self-supported on the floor of the open space. The support frame includes a series of head rails supported by a series of vertical columns resting on the floor. The vertical columns support a series of wall panels and the head rails support a ceiling such that the ceiling is supported by the support frame independent of the wall panels. The ceiling of the enclosed room is created by a series of ceiling panels and at least one air intake panel and at least one air exhaust panel. The air exhaust panel includes an exhaust fan that removes air from within the enclosed room and draws fresh air into the enclosed room. The ceiling can include a plurality of adjustable louvers and lighting.

The invention relates to a method of manufacturing a prefab construction element (11), preferably a load-bearing element, for frame construction, such as wood frame construction, comprising the steps of providing a roofing, flooring or wall panel (2), which panel (2) comprises an enclosure (3), providing a fungus and a substrate, introducing or preparing a mixture (10) of the fungus and the substrate, in the enclosure (3) and allowing the fungus to grow to form a network of hyphae through the mixture (10) and into the walls (4-7) of the enclosure (3) to form a mycelium composite, and drying the composite while it remains in the enclosure (3) of the panel (2).

The present invention relates to a building system for erecting a building structure. The building system comprises a plurality of precast transportable concrete wall panels; each wall panel comprising a reinforcement structure and a plurality of cast-in connecting inserts, each connecting insert being located at a predetermined position; and a precast transportable concrete floor panel, the floor panel also comprising a reinforcement structure and a plurality of cast-in connecting inserts, each being located at a pre-determined position, the floor panel further comprising a recess along at least a portion of a perimeter of the floor panel. The building system is configured such that when each precast wall panel is positioned in a substantially upright position in the recess of the floor panel, connecting inserts of two adjacent panels align so that the panels can be connected using a plurality of mechanical fasteners.
