Definitions

  • the present invention relates to blocks which are conventionally employed to build privacy and retaining walls. More particularly, the device herein disclosed relates to a block system which allows the user to employ only two types of block to build any wall and optionally three types.
  • the system employs a full sized block having a novel "H" shape. An entire wall may be formed of this single block.
  • the unique "H" shaped block and "C” shaped block allow the user to build a wall with a high degree of sheer strength through the provision of projecting pins which engage with overhead blocks in the formed wall. Additional strength in the formed wall may be provided through interweaving vertical metal reinforcing bars which communicate through the levels of engaged blocks.
  • the device and method herein disclosed yields great utility by allowing the reinforcing bars and blocks to be interfaced without the need to lift the heavy blocks over the top of distal end of the metal bar as is conventionally done. Walls with reinforcing bars can thus be built quicker and with less exertion and injuries to the workers building.
  • the endwalls of the blocks used are open and allow the blocks to simply be angled around the reinforcing bar and engaged with each other with formed pins which project above the top surface of each block and engage with cavities in the bottom of overriding blocks. Projecting endwall tongue and groove engagement is also provided for an extremely strong engagement of all the blocks forming any one wall. The resulting wall is built in less time and provides resistance to earthquakes and other lateral forces which might cause failure in walls lacking the structural integrity provided by the interlocking system of pins and cavities and allowance for easy use of reinforcing bar.
  • the steel reinforcement rods must be threaded through closed cavities of conventional blocks used, and once all the blocks and steel are properly placed, mortar, grout or similiar cement-like material is then filled into the closed cavities. The cementitious material, once dried, will lock the metal bars and the blocks in a fixed engagement with each other.

  • Conventional concrete blocks generally offer no endwall means of engagement to adjacent blocks in a given layer either, instead, conventional concrete blocks are designed to be aligned in individual layers of adjacent blocks with subsequent layers formed in the same fashion stacked on top of each other. The grout or mortar must be properly mixed and then expertly applied to each individual block surface that engages an adjacent surface to insure that all blocks in all layers remain engaged by the dried mortar.
  • Non-interlocking blocks in the hands of a good mason may be laid apart and separated by mortar at varying distances to either stretch or shrink the resulting wall.

Further, such a device and system should provide a means to interlock adjacent blocks on the same level of the wall to provide additional shear strength to the wall once build. Still further, such a device and method should be simple and have as few parts to the block building system as possible to allow for use by unskilled, uneducated workers, and to minimize the number of types of blocks that must be shipped to a building site.

  • the device employs a one block building system providing for building of a wall structure formed of single interlocking block style.
  • the device 10 provides great utility in the building of walls with interlocking blocks 12 as shown in figures 2 and 6, using a generally "H" shaped primary blocks 12 which can be employed as the sole block used in building a wall 14.
  • the block 12 is formed in this shape by a pair of parallel sidewalls 30 extending from a middle portion 31.
  • the primary block 12 will allow for the building of straight walls or walls with corners engaged to traverse walls 15 where the primary block 12 would be employed as a corner block anchoring the walls perpendicular to each other.
  • the primary block 12 When employed as a one block method or system, the primary block 12, on a retaining wall can have its opposing open ends 16, at both termination points at the sides of the wall, filled with mortar or concrete or simply left open and filled with adjacent soil if the wall 14 is a retaining wall. Or when employed as a one block system to build a building, the primary block 12 will function as a corner block 18 to provide interlocking corners to the walls on every other layer of blocks forming the building walls.
  • half blocks 19 or specially configured secondary blocks 21 might be employed as an option to yield more aesthetically pleasing results on a straight wall such as shown in figure 6; however, because of the interlocking capabilities of the primary block 12, when used for a retaining or other straight wall, the half blocks 19 might also be left out of the wall and any half gaps between layers of blocks 12 covered with adjoining soil or filled with concrete for aesthetic purposes while still yielding a perfectly sound and strong straight wall.
  • the primary block 12 incorporates a number of means for interlocking with adjacent primary blocks 12 or secondary blocks if employed, which improve both the strength and stability of walls 14 and structures formed of one wall or engaged to adjoining walls 14.
  • At both ends of the primary block 12 are open ends 16 exposing first and second internal cavities 20.
  • two open ends 16 communicating with internal cavities 20 on the primary block 12 provide for improved interlayer communication of reinforcing bar 22.
  • the open ends between the distal ends of the block sidewalls 30 also provide for easy placement of individual primary blocks 12, engaged with reinforcing bar 22 through multiple layers 26, without the need to lift the heavy primary blocks 12 over the elevated distal end 24 of the reinforcing bar 22 and subsequently supporting the heavy block while it is lowered into position as is done with conventional blocks.
  • walls 14 having reinforcing bars 22 vertically interposed between layers 26 of overlying and underlying primary blocks 12, may be quickly constructed with much less effort since the primary blocks 12 may be angled into place between fixed reinforcing bars 22 and then engaged with adjacent primary blocks 12 as depicted in figure 2.
  • the primary block 12 or the second block when optionally employed may then be secured in an interlocking engagement with blocks in adjacent underlying layers 26, and with primary blocks 12 in adjacent positions on the same layer 26, using one or more means for interlocked engagement.
  • a first means for interlocked engagement is provided for interlocking all of the primary blocks 12 on an individual layer 26 with adjacent coplanar primary blocks 12.
  • This interlocked engagement is provided by interlocking of the pairs of distal ends 28 of the sidewalls 30 of adjacently located primary blocks 12.
  • Means for interlocking the distal ends 28 with the distal ends 28 of adjacently located coplanar primary blocks 12, in the current favored mode of the device 10, employ a projection 32 adapted for engagement in a recess 34 on the matching distal end the adjacent primary blocks 12.
  • FIG 8 A particularly preferred mode of the projections 32 is shown in figure 8 wherein the projections 32 are tapered which tend to help the block self-align when being angled in place around reinforcing bar.
  • the taper makes it much easier to angle the block 12 while concurrently engaging the two pair of respective distal ends of adjacently laid blocks 12 in a layer 26.
  • all of the primary blocks 12 are provided a means for interlocking primary blocks 12 on one layer 26 to adjacent primary blocks 12 in layers 26 above and below any primary block 12 in any layer 26.
  • the only layer 26 not engaged to primary blocks 12 below it would be the first or lowest layer 26 in the wall 14, since there are no interlocking pins 36 below it on other blocks 12.
  • the pins 36 can be formed in that foundation top surface, providing an excellent engagement of the bottom layer to its underlying foundation.
  • interlocking pins 36 which project above the substantially planar top surface 38 of the primary blocks 12.
  • the pins 36 are adapted for cooperative engagements between internal shoulders 40 engaged to the planar inner surface 41 of each side wall 30.
  • the shoulders have side edges 35 which are evenly spaced a distance from the center of the block 12.
  • a first side surface 39 of the pins 36 adjacent to the top surface 38 of the block 12 substantially coplanar with the inner surface 41 of the sidewall 30 from which the pin 36 extends above the top surface. It is thus adapted for a frictional engagement on the inner surface 41 on an overhead coplanar primary blocks 12 located with distal ends substantially centered on the underlying block 12.
  • a second side surface 44 traverse to the first side surface 39 of the pins 36 is adapted for engagement against, or spaced from, the side edges 35 of the shoulders 40 of the overhead primary blocks 12. This provides two means of engagement of the lower primary blocks 12 with those above.
  • the distal end of the pins 36 would taper from their center axis to their side edges to provide a tapered point 45 to provide a means for self alignment of primary blocks 12 on higher layers 26 with those on lower layers when laid thereon.
  • the blocks 12 structurally will be the same with or without the points 45 so they could be made without them and such is anticipated.
  • a second side surface 44 of the pins is adapted for engagement on, or space by a gap 43 from, a respective side edge 35 of the shoulders 40.
  • the side edges 40 of the shoulders are spaced a distance substantially equidistant from the center of the block 12.
  • This distance "D" is slightly more than the distance from the opposing side surfaces 44 of two blocks 12 engaged fully at their distal ends 28 providing a slight gap 43 between one or both of the side surfaces 44 and the side edges 35 when the distal ends are fully engaged.
  • This gap 43 provides a means for allowance of the spacing between adjacent blocks 12 from each other from a maximum spacing where there is no gap 43 to a minimum spacing where the gap 43 would be its greatest from one or both side surfaces and side edges 35.
  • Adjustment of the spacing, and therefore the wall length may be achieved by changing the spacing of the sliding engagement of the distal ends 28 of the blocks 12 during the layering building process.
  • the maximum gap 43 is about 1/8 of an inch providing up to that much adjustment of block spacing at each engagement of distal ends 28.
  • other maximums might be employed and are anticipated.
  • the distal ends 28 of each adjacent block 12 remain fully engaged with the projection 32 and recess 34 since they will slide in their engagement to allow the adjustment. With such a longitudinal adjustment of up to 1/8 inch in the current preferred mode of the device 10, this would allow for an inch adjustment for every eight blocks 12 engaged in a layer of a wall 14 and thus an adjustment of the length of the formed wall 14 even through all the blocks 12 in the wall 12 would still remain interlocked.
  • the primary blocks have a plurality of the pins 36 projecting above their respective top surfaces 38 adapted for engagement against the inside surfaces 41 of above mounted blocks 12 and a spaced engagement both shoulders 40 providing means for lateral translation of the blocks 12 in their engagement at their distal ends 24 to adjust wall length and fitment of the blocks 12 with each other.
  • the slidable projections 32 engaged into recesses 34 all of the distal ends 28 of the sidewalls 30 are also engaged and will also allow for a translation back and forth in that engagement.
  • another especially preferred mode of the device 10 may be a means for communicating reinforcing bar 22 vertically through adjacent horizontal layers 26 formed of the primary blocks 12.
  • the current preferred mode of providing the means for communicating reinforcing bar 22 through the layers is provided by adapting the internal cavities 20 of the individual primary blocks 12 for alignment with those of other layers.
  • the internal cavity of lower layered blocks 12 aligns with a portions of the internal cavities 20 of above situated blocks 12 no matter what layer 26 they are located upon.
  • This adaption for alignment provides a path 46 for reinforcing bar 22 through the layers 26, and also forms a channel 48 communicating between blocks 12 on adjacent layers 26 through which mortar or other cementitious material deposited into an upper layer 26 of the wall 14 will communicate into lower layers 26.
  • a horizontal channel 52 communicating through all engaged adjacent blocks 12 in the layers 26 of engaged primary blocks 12.
