Concrete wall supports that reduce or eliminate wall movement due to exterior horizontal forces. One support is a bracket mounted to a floor joist with a plate extending below the top of the wall and two legs extending from the plate and attaching to the joist. One leg is above the concrete wall on one horizontal side of the plate, and the other leg is on the opposite side of the plate. Another support has a plate that extends below the top of the wall with two legs on opposite sides of the joist above the wall. A leg attaches to the lower edge of the joist. A support against shear forces includes a highly water permeable aggregate composite disposed in the voids of the wall, with a supportive strip that is enclosed in the aggregate composite and extends out of the voids to the face of the wall.

Precast blocks with a rectangular or quadrangular prism shape contain a normal weight hydraulic concrete casing, lightweight concrete or similar material, for building walls or slabs. The steel-reinforced blocks for walls, mezzanine or rooftop slabs have the length of the wall or slab to build. An acoustic, thermal-insulating lightweight material housed in the interior simultaneous provides for blocks sufficiently lightweight to transport and install manually on-site. For walls, the blocks are tongued and grooved on the top and bottom sides and placed horizontally one on top of the other using block or similar adhesive therebetween. In the corners or T intersections, blocks are alternatively placed and form armed headframes for stability and resistance. For blocks for slabs, the tongue and groove system is on the sides, installed one beside the other, using block or similar adhesive therebetween. Transversal rods to the slab are placed to avoid temperature retraction.

A polyurethane foam block can include a base having a plurality of recesses and a top surface having a plurality of connective components protruding outward from the top surface where each connective component of the plurality of connective components can align with a recess of the plurality of recesses. The polyurethane foam block can include a plurality of sidewalls extending upward from the base and defining an interior and a plurality of partitions extending from the base to the top surface to divide the block into a plurality of cavities. A wall can include base blocks and header blocks. The header blocks can be shaped and constructed similarly to the base blocks with one exception being the header blocks can include an-upward facing channel cutout. The wall can include a beam extending through channels of header blocks.

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 hollow prefabricated masonry wall panel is made at a fabrication site and is configured for transportation to a build site. The hollow prefabricated wall panel has a base row and an upper row formed of hollow blocks. A slit is formed in the top of each of the two side walls of the hollow blocks of the base row and upper row, the slit having a width no larger than 20% a width of a side wall. Provisional reinforcement is provided within each slit with a bonding material, a size of the slit and the provisional reinforcement configured to provide tensile strength during transportation of the hollow prefabricated wall panel from the fabrication site to the build site. At least one mid-row is laid between the base row and upper row so the hollow cavities are aligned to preserve hollow wall cavities that can accept code required reinforcement once transported to the build site.

Concrete wall supports that reduce or eliminate wall movement due to exterior horizontal forces. One support is a bracket mounted to a floor joist with a plate extending below the top of the wall and two legs extending from the plate and attaching to the joist. One leg is above the concrete wall on one horizontal side of the plate, and the other leg is on the opposite side of the plate. Another support has a plate that extends below the top of the wall with two legs on opposite sides of the joist above the wall. A leg attaches to the lower edge of the joist. A support against shear forces includes a highly water permeable aggregate composite disposed in the voids of the wall, with a supportive strip that is enclosed in the aggregate composite and extends out of the voids to the face of the wall.

The present invention includes a method and a unit for a masonry wall system, each unit comprising a face shell wherein the interior surface has a transverse axis running from the top surface to the bottom surface of the face shell, and one or more webs having a front end and a rear end, wherein the rear end of each web is integral with or attached to the interior surface of the face shell along the transverse axis. The method for wall construction further comprising positioning one or more vertical reinforcement rods or tendons with one end embedded in a wall-foundation and laying a layer wall units on the wall-foundation such that the one or more webs of the layers of wall units are aligned, and the vertical reinforcement rods or tendons run through or are adjacent to the webs of the wall units.
