A lintel system for supporting masonry blocks above an opening in a structure includes a lintel configured to span a width of the opening. The lintel includes a plurality of elongate splice plates each having opposite longitudinal ends. The splice plates are attached together end to end such that a longitudinal end of each splice plate is attached to a longitudinal end of at least one other splice plate.

A lintel system for supporting masonry blocks above an opening in a structure includes a lintel configured to span a width of the opening. The lintel includes a single spanning member having a top edge, a bottom edge, and a side face extending between the top and bottom edge. Supports are disposed at longitudinal ends of the single plate member. A stiffener is attached to the lintel for reinforcing the lintel. The stiffener extends in opposed relation to the side face along at least a portion of the side face.

A lintel for use in supporting construction blocks over an aperture in a wall including the construction blocks, the lintel comprising a lintel body defining substantially longitudinally opposed end sections and an intermediate section extending therebetween, the lintel body defining a block supporting element in the intermediate section for supporting the construction blocks over the aperture; and a pair of end elements each mounted to a respective one of the end sections, each of the end elements defining a lintel supporting element for supporting the lintel in the wall between adjacent rows of the construction block on a respective side of the aperture. Each of the end elements is securable to a respective lintel body end section at upper and lower positions relative thereto. Also, a wall including the lintel.

A hollow prefabricated masonry lintel made at a fabrication site and configured for transportation to a build site has a base row formed of U-shaped blocks laid end to end with adjacent ends adhered with mortar. A hollow horizontal cavity along a length of the base row is formed of each recess of the U-shaped blocks. A slit is formed in a top surface of each of the two side walls of the U-shaped blocks along the length of the base row, the slit having a width no larger than 20% of a width of the top surface. Provisional reinforcement is fully embedded within the slit with a bonding material, with a size of the slit and the provisional reinforcement providing tensile strength during transportation of the prefabricated masonry lintel from the fabrication site to the build site with the hollow horizontal cavity having no grout and no code-required reinforcement.

A load-bearing wall can be provided with a header comprising engineered wood web manufactured truss can be provided over the opening of the load-bearing wall. Insulation can be applied to the open areas of the truss to increase the thermal resistance of the header. The portion of the load-bearing wall can be constructed as a manufactured wall panel and incorporated with traditional stick framing. The manufactured wall panel can include straps to facilitate lifting, transporting and installation of the panels.

A cantilevered peripheral portion of a light frame construction building, having a peripherally bounded interior, is disclosed. The cantilevered peripheral portion involves two structural engineered wood rim boards each having cavities facing the exterior of the building and joined at their terminal ends at an angle. One of the two structural engineered wood rim boards supports a first group of studs located above, along, and supported by, an upper flange a first of the two structural engineered wood rim boards. At least one supporting wall stud is located beneath a lower flange of a second of the two structural engineered wood rim boards such that a cantilevered overhang configuration is formed between the first group of studs and the at least one supporting wall stud.

A containment device including a dry curtain, adapted to be deployed for the containment or re-containment of a discharge area, such as an opening, e.g. a door, in response to an explosion. The device includes a ballast bar in the lower portion of the curtain, the ballast bar including cylinders of high-density foam alternated with cylinders of compressible low density foam.

A peripheral portion of a light frame construction building constructed from structural engineered wood components involves first, second and third structural engineered wood rim boards each having a cavity on an exterior-facing side and a substantially flat interior-facing side, with ends of the second and third structural engineered wood rim boards abutting each other to form a corner, and an auxiliary corner support affixed to, and within the cavities of, the second and third structural engineered wood rim boards.

A pre-formed header assembly creates a rough wall opening for a metal door/frame, permitting completion of electrical, ducting, drywall, etc. prior to receiving/installing the door frame. The header is secured to first and second king studs at respective locations positioned beyond a desired door frame location. The header includes four different channels, one of which is utilized at two locations. The first channel has a first length to span between the king studs. The second channel has a second length, and the third channel a third length, which correspond to minimum dimensional requirements for completing the wall. The base of the second and third channels are each fixedly secured to the base of the first channel. The base of the fourth and fifth channels are fixedly secured to the first and second ends of the base of the first channel, respectively, substantially perpendicular thereto, for attachment to the king studs.

Concrete masonry unit blocks with recesses providing pockets sized to receive dimensional lumber components, enabling easy design and fabrication of block and lumber assemblies, typically using construction adhesive to bond the blocks to each other. Various dimensions and shapes of blocks are possible, as well as numerous shapes and sizes of pocket-forming recesses in the blocks. A wide variety of attractive and functional structures can be built with the blocks of this invention and widely-available dimensional lumber.
