  • In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawing figures might not be to scale and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.
  • FIGS. 1A through 1C are diagrams of a retaining wall block 100 in accordance with an exemplary embodiment of the present disclosure. Retaining wall block 100 can be formed from masonry, concrete or other suitable materials, using a wet cast process, a dry cast process or other suitable processes. As shown in FIG. 1A, retaining wall block 100 includes a top face 105, engagement cavity 110, and textured front face 115. Textured front face 115 can be formed by splitting retaining wall block 100 from a second retaining wall block 100, as discussed in greater detail below. As shown in FIG. 1B, which is a front view of retaining wall block 100, front face 115 includes a false joint 120 for aesthetic purposes.
  • As shown in FIG. 1C, which is a side view of retaining wall block 100, retaining wall block 100 further includes bottom surface 125 having at least one engagement protrusion 130. Engagement protrusion 130 is configured to interface with engagement cavity 110 of an underlying retaining wall block 100. Furthermore, the front engagement cavity 110 is offset from the location of engagement protrusion 130, so as to result in a staggered incline as successive rows of retaining wall blocks 100 are formed. In one embodiment of the present disclosure, the incline of successive rows of retaining wall blocks 100 is generally vertical with no staggering.
  • FIGS. 2A through 2C are diagrams of two engaged retaining wall blocks 100 and 200, in accordance with an exemplary embodiment of the present disclosure. As shown in FIG. 2A, retaining wall blocks 100 and 200 include top faces 105 and 205, respectively, engagement cavities 110 and 210, respectively, and textured front faces 115 and 215, respectively. As previously discussed, retaining wall blocks 100 and 200 can also have false joints 120 and 220, respectively, for aesthetic purposes, as shown in FIG. 2B. Likewise, other suitable false joints can also or alternatively be used.
  • In one embodiment of the present disclosure, first retaining wall block 100 is disposed onto a top surface 205 of a second retaining wall block 200. As shown in FIG. 2C, first retaining wall block 100 can positioned so that engagement protrusions 130 align with and fit into engagement cavity 210 of second retaining wall block 200.
  • In, one embodiment of the present disclosure, the angle and configuration of engagement notches 110 and 210 and engagement members 130 and 230 can be varied to allow the blocks 100, 200 to be assembled with an offset. In one exemplary embodiment of the present disclosure, the angle of engagement notches 110 and 210 can be between about 30 degrees and about 90 degrees. Likewise, the angle of engagement members 130 and 230 can be between about 30 degrees and about 90 degrees.
  • FIGS. 3A and 3B are diagrams of retaining wall blocks 302A, 302B and 302C, in accordance with an exemplary embodiment of the present disclosure. FIG. 3A shows an overhead view of retaining wall blocks 302A, 302B and 302C, with block 302A centered over blocks 302B and 302C. In addition, internal support 304A of block 302A is aligned with internal support 306B of block 302B, and internal support 306A of block 302A is aligned with internal support 304C of block 302C.
  • FIG. 3B shows an underside view of retaining wall blocks 302A, 302B and 302C. As can be seen, the blocks are H-shaped, and each include engagement cavities on a top surface and engagement protrusions on a bottom surface that can interlock with the engagement cavities at the top of underlying blocks. The location of the engagement cavities and engagement protrusions is adjustable, as previously described, so as to allow the angle of incline for the wall to be selected.
  • FIG. 4A through 4B are diagrams 400A and 400B of a mold for manufacturing retaining wall blocks, in accordance with an exemplary embodiment of the present disclosure. The mold can be formed from steel or other suitable materials, and can be configured to handle masonry, cement or other suitable materials.
  • As shown in FIGS. 4A through 4B, the mold includes a base portion 402 having a ridge 404, which is used to form the notch at the top of the block. The body 406 of the mold is placed on top of the base portion, and a shoe 408 with adjustable inserts 410 and 412 are provided that can be used to create blocks with different angles of incline, such as to allow a wall designer to specify an angle of incline. Inserts 410 and 412 interlock with shoe 408, such as by using a mechanical interlock device, screws or in other suitable manners.
  • FIG. 5 is a diagram of a mold shoe 500 in accordance with an exemplary embodiment of the present disclosure. Mold shoe 500 includes body 502 and insert channel 505 that can be used to change the location of the at least one engagement protrusion. For example, by using insert A 510, the location of the at least one engagement protrusion is farther back than when using insert B 515. The location of the at least one engagement protrusion defines the incline of the wall, such as to allow the incline to be adjusted based on design specifications.
  • FIG. 6 is a flow chart of a method for manufacturing a retaining wall with an adjustable incline angle, in accordance with an exemplary embodiment of the present disclosure. Method 600 begins at 602, where an inset associated with a selected angle of incline is selected and incorporated into a mold. In one exemplary embodiment, the inset can be configured to interlock with a shoe of a mold assembly, such as by using a mechanical interlock, can be secured using screws or can otherwise be attached to the mold assembly. The method then proceeds to 604.
  • At 604, the mold is filled with masonry, cement or other suitable materials.
  • At 606, the shoe is used to compress the material into the mold and the shoe and mold is then removed.
  • At 608, the material is allowed to harden.
  • It should be emphasized that the above-described embodiments are merely examples of possible implementations. Many variations and modifications may be made to the above-described embodiments without departing from the principles of the present disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
