Abstract: An apparatus and method for dressing marginal areas of externally viewable surfaces of a building block. The apparatus includes at least one chipper having rotational axis and a plurality of outwardly extending teeth randomly disposed thereabout. The chipper is positioned and oriented so that its teeth may effectively work a predetermined marginal area of interest. As the predetermined marginal area of interest and the teeth of the chipper are brought into contact with each other, portions of the marginal area are randomly impacted and fractured to form an erose or jagged surface that resembles hand dressing. The apparatus may also include additional chippers, each having a rotational axis and a plurality of teeth randomly disposed thereabout.

Abstract: A dry-stackable masonry brick having a top surface, a bottom surface, a front surface, a rear surface, and opposing side surfaces. The brick is provided with a plurality of channels, which extend along the top, bottom and one side of the brick. The channels are configured and arranged so that they are able to receive a projection from one or more adjacent bricks in an interlocking relation. The brick may be positioned on either of the opposing sides in a vertical orientation, with the bottom side up, or even with the rear surface facing forwardly. The front and rear surfaces of the brick may be provided with different surface treatments to increase the number of differently configured walls that may be constructed. Moreover, the front and rear surfaces may be provided with marginal areas that are configured so that they are able to receive and retain filler material.

Abstract: A block for use in constructing a multiple course retaining wall comprises a top surface, a bottom surface spaced apart from the top surface, opposing side surfaces, a front surface and a back surface. The bottom surface may include a pair of contacting portions that contact a top surface of a lower course of blocks when the block is placed on a lower course of blocks and a gap defining portion located between the contacting portions. The front surface may have generally planar upper and lower edges when viewed in front elevation and has a width extending between the side surfaces that is greater than the width extending between the side surfaces of back surface. At least one of the contacting portions may intersect front surface.

Abstract: An invertible retaining wall block comprises a front portion, a rear portion and a neck portion connecting the front portion and rear portion. A projection extends outwardly from the block to interlock with similar blocks in adjacent courses of blocks. One or more notches are provided to the front portion in order to allow the base course of blocks to be placed in an inverted orientation with respect to subsequent courses because the notch provides clearance for the protrusion.

Abstract: A wall structure (10, 110) and method of construction. The wall structure (10, 110) comprises a plurality of preformed, lightweight blocks (12, 112) supported and interconnected by a plurality of elongated, vertically oriented, collateral support beams (16, 116). Preferably, the support beams (16, 116) are operatively connected to an appropriate substructure (62, 100) and the lightweight blocks (12, 112) are operatively connected to the support beams (16, 116). The blocks (12, 112) and support beams (16, 116) are configured so that when they are connected to each other, a space is formed between the wall structure (10, 110) and the substructure (62, 100). Thus, an assembled wall structure (10) may be setoff from a substructure and the substructure (62, 100) may be used for other purposes.

Abstract: A retaining wall with a series of differently sized, pre-formed blocks. Each block includes a projection and a recess, with the projection and recess arranged and configured so that each projection effectively engages a recess in an adjacent course to connect and align adjacent courses in registry. Retaining walls made of horizontal blocks may be stacked in columnar fashion or running bond fashion. The location of the indexing surface on a projection relative to the viewable surface of the block may be varied to enable adjacent courses to be coplanar or tiered in a variety of predetermined offset distances.

Abstract: A block for use in constructing a multiple course retaining wall. The block has a substantially planar top surface, a front surface, wherein said front surface is of a substantially curvilinear shape, a rear surface, opposed side surfaces, and a bottom surface. The bottom surface has a predetermined area and a non-planar portion, with the non-planar portion comprising a continuous area making up at least one-quarter of the bottom surface and creating a cavity between the bottom surface of the block and a top surface of a lower course of blocks when the block is placed on the top surface of the lower course of blocks. The cavity allows dirt and other foreign matter to exist between successive courses of blocks without creating instability between the block and the lower course of blocks.

Abstract: A wall structure (10) comprising concrete composite masonry blocks (12) supported and interconnected by elongate support beams (16) is disclosed. The blocks (12) are shaped to be stacked in vertically independent columns (14) and are held in place by the specially shaped, lightweight support beams (16) placed between the adjacent columns (14). The wall structure (10) may be adapted for use as a bearing or non-bearing wall.

Abstract: A fastening element for operatively connecting masonry units together in a fixed relation. The fastening element comprises a body with a web having opposing surfaces, and a plurality of projections that extend in a generally perpendicular direction therefrom. The projections are spaced apart from each other and configured to engage portions of masonry units therebetween in a constrained relation. The fastening element permits two, three, or four masonry units to be operatively connected together in variety of configurations without the use of mortar.

Abstract: A block for use in constructing a retaining wall. The block has a bottom with a non-planar portion that forms a gap between the block and the top surface of a lower course of similar blocks when the block is placed thereon. This gap allows the block to rest on the lower course of blocks in a stable, level manner by providing a space that can accommodate small amounts of intrusive material such as rubble, dirt, or miscellaneous debris which would otherwise interfere with the stacking of the blocks. The block's bottom may also include a plurality of grooves that provide additional clearance in the gap for larger bits of intrusive material such as pebbles or small stones. Preferably, the grooves have angled walls which act to funnel the larger bits of intrusive material into an area of adequate clearance when the block is being placed on a lower course of similar blocks.

Abstract: A wall structure comprising a plurality of columns of preformed, lightweight, stacked blocks, with the columns of blocks connected to each other by a plurality of elongated, vertically oriented, support beams. Preferably, the wall structure is operatively connected to a structure by one or more brackets. Each bracket includes a wall engaging portion and a structure engaging portion, and is configured and arranged to allow constrained movement of the wall structure in a predetermined direction. Preferably, the bracket is positioned such that the wall engaging portion is collaterally aligned with the longitudinal axis of a support beam so that one surface of the wall engaging portion is in a confronting relation therewith and an opposing surface of the wall engaging portion is in a confronting relation with a block.
