A modular wall unit for a modular wall system includes a first elongate reinforcement member comprising at least one tubular portion for connecting the wall unit to a further wall unit of the wall system. The wall unit also includes a body at least partially surrounding the reinforcement member along its elongate length. The reinforcement member provides strength to the wall unit and allows a connecting element to engage with the at least one tubular portion. The connecting element can connect the wall unit to a further wall unit. This allows formation of a wall system where multiple wall units are interconnected via the reinforcement members and connecting elements. A kit including a wall unit and one or more plugs for assembling a plurality of wall units, a method for forming a wall unit, and a hanging device for supporting a frame are also described.

A block and various block assemblies are disclosed. The block has at least one side including one or more tapered slots. Each of the slots has one or more apertures. The at least one side has a bottom end comprising at least one footing and a top end comprising a groove. Blocks are stacked by fitting the footing of one block into the groove of another block. A block assembly comprises a first block, a second block, a double key, and connector tubes. The first block is connected to the second block using the double key, which is inserted into a slot on each of the blocks. A connector tube is threaded through apertures on the slots and the double key.

A refractory insert is provided, including a main body part having a first surface defining a first sidewall, an opposed second surface defining a second sidewall, and an outer peripheral surface separating the first and second surfaces, and a mechanical mating member provided on at least a portion of the outer peripheral surface thereof. The mechanical mating member includes a retention mechanism for controlling and retaining a position of a corresponding mating member in connection therewith.

Modular building methods and systems using lightweight modular panels, and specially configured transition panels for transitioning from wall to floor, or from wall to roof. Identically configured standard panels are used for constructing the walls, floor, and roof, with transitions from one structure to the next (e.g., wall to floor, or wall to roof). Each of the variously configured panel types includes channels (e.g., 2 pair of channels) formed through the length of the foam body, where the channels are configured to receive splines (e.g., flanges of an I-beam) therein. In the standard panel, the channels may include pairs of top and bottom channels, with the channels offset towards the respective panel major faces. In the transition panels, the channels may be similarly configured, but positioned differently to make the appropriate transition. The splines are connected to a frame, which acts as a template and transfers loads to a foundation.

An outdoor structure and structural system including a plurality of structural blocks having opposed top and bottom surfaces, opposed front and rear surfaces and opposed first and second side surfaces, the bottom surfaces of the plurality of structural blocks having a receiving channel extending along the bottom surface from the first side surface towards the second side surface, the receiving channel sized and shaped to receive and retain a hanger. The outdoor structure and structural system also including at least one bridging lintel, the bridging lintel having an upper surface, front and rear sides and first and second sides, the bridging lintel having first and second hangers extending from the upper surface of the bridging lintel, the first hanger extending a distance along the upper surface and a distance outward from the upper surface beyond the first side of the bridging lintel, the second hanger extending a distance along the upper surface and a distance outward from the upper surface beyond the second side of the bridging lintel.

Embodiments relate to an enhanced method for building walls by primarily reducing the time for assembly. The design is for a molded multi-segment plastic composite construction block that interlocks horizontally, vertically and orthogonally with a clearance-fit, does not require mortar for structural integrity and is self-aligning. The blocks are molded out of natural-fiber reinforced thermoplastic composites with thermal expansion coefficient less than 0.0002 per degree Celsius and compression strength greater than 60 MPa.

A refractory block assembly for a steam reformer furnace tunnel includes a hollow main body portion having at least one through-hole having openings formed in a first side and an opposed second side of the hollow main body portion. At least one refractory insert member, having mechanical mating features on at least a portion of the outer surface thereof, resides within at least one of the at least one through-hole of the hollow main body portion.

An insulated construction panel having a top end, a bottom end, a first end, a second end, a front side and a rear side, the panel for constructing a single or multi-thickness concrete form, the panel including regularly spaced coplanar passages extending completely through the panel from the top end of the panel toward and through to the bottom end of the panel. For each of the regularly spaced coplanar passages, an angular passage perpendicularly intersecting each coplanar passage at the top end and extending toward and through a portion of a front side surface of the front side and rear side surface of the rear side of the panel, each angular passage extending only partially through the panel from the top end toward the bottom end. For each of the regularly spaced coplanar passages, an angular passage perpendicularly intersecting each coplanar passage at the bottom end and extending toward and through a portion of the front side surface of the front side and the rear side surface of rear side of the panel, each angular passage extending only partially through the panel from the bottom end toward the top end.
