Abstract
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.
