A wall construction system including plurality of interlocking concrete blocks. The interlocking blocks include one or more stretcher blocks, corner blocks, and half blocks. The blocks include top and end shear lugs and bottom and end grooves. The bottom grooves accommodate the top shear lugs of blocks in a lower course of stacked blocks. Corner blocks provide a means for creating a corner and turning the direction of a course of blocks by 90 degrees. The interlocking features of the blocks enable dry-stacking in successive courses to construct a wall or multi-wall structure. When stacked end to end in successive rows, the top and end shear lugs of each interlocking block engage complimentary grooves in the underlying, overlying, and adjacent blocks thereby enabling the blocks to rapidly self-align vertically and lock together as they are stacked. The resulting dry-stacked structure exhibits a high lateral resistance to overpressures or transverse loads.

A wall construction system includes multiple block types that interfit with one another to form walls in a staggered arrangement. Block types include jamb blocks having front and back surfaces, a planar surface on a first end, and a second side having a projecting surface or a receiving surface configured to mate with the projecting surface. The jamb block includes a top mating surface and a bottom mating surface configured to mate with the top mating surface. Webs extend from the front surface to the back surface to form voids. A multi-directional elevation is formed over a void adjacent the planar surface to permit stacking of blocks in two orientations. Other block types include a half jamb block having a web to form a void and a planar surface, and a web stretcher having a projecting surface on one end and a receiving surface on another end.

A masonry block that is particularly well suited for the construction of narrow walls, such as interior building walls, that is adapted to receive conventional utilities and reinforcing supports.

A system of retaining wall blocks, a method of assembling a retaining wall block assembly, and a mold for manufacturing retaining wall blocks having adjustable engagement configurations.

A building system used for constructing a building is disclosed in the present invention. The building system includes: a first block, a corner block and a connection block interlocking with each other for constructing the building; wherein, dimensional relations between the first block, the corner block and the connection block satisfying the following conditions: Lco=L+W; Wco=L+W; Lci=L; Wci=L; Lcb=L; Wcb=W; Wherein, is a length of the first block; W is a width of the first block; Lco is an outer length of the corner block; Wco is an outer width of the corner block; Lci is an inner length of the corner block; Wci is an inner width of the corner block; Lcb is a length of the connection block; Wcb is a width of the connection block.

A method for retrofitting a preexisting wall to include bullet resistance. The retrofitted wall incorporates ballistic paver blocks that are capable of augmenting either an interior or exterior wall. The flexibility gained by using ballistic paver blocks affords cost and weight savings over traditional concrete, or alternatively, metal shielding.

The present invention relates an integrated, post-tensioned building construction system that utilizes a rectangular array of interlocking block components for the shell of building structures. Internal tendons that pass through the interlocking blocks are affixed to beams at the base or foundation of the building walls and terminate above beams atop the building walls. The ends of tendons receive mechanical fasteners that are tightened to the beams and/or foundation. The tendons serve to maintain the integrity of the interlocking block components, which cannot come apart when the tendons are tightened. Build stops secured to tendons help to stabilize the interlocking block components during construction. With interlocking blocks fabricated from a compressible material, like concrete-and-aggregate, the tendons are tensioned to induce a compressive load on the material. Inducing compression in the structure by tensioning the internal tendons augments the strength of the entire building by introducing an internal compressive stress that partially counteracts the tensile stresses caused by external loads applied to the structure, such as by windstorms, seismic events, or settling of the foundation.

The present disclosure relates to the building industry and in particular to a block for use in automated building construction. In one aspect, the block comprises a generally cuboid body having a top and a base, a length extending between a pair of opposed ends, and a width extending between a pair of opposed sides; the body including a plurality of hollow cores extending from said top to said base, and arranged in a row between said opposed ends; wherein each core has a rectilinear cross-sectional shape; and wherein the thickness of the block between each pair of adjacent cores is at least double the thickness of the block on all other sides of each core, so that the block is divisible into a plurality of substantially identical block portions, each portion including four walls of substantially uniform wall thickness about its core.

A retaining wall block having a false joint and a system of retaining wall blocks. The retaining wall block includes a body having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can have a depth divided by the width greater than two inches. The false joint can have an interior angle of less than ten degrees. The system includes a plurality of retaining wall blocks and a first course of retaining wall blocks engaged with a second course of retaining wall blocks below. Each block in the system comprising a front face having a first textured surface and a second textured surface and a false joint dividing the first and second textured surface. The false joint can extend a predetermined depth of a third surface.
