DETAILED DESCRIPTION

(11) In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration, and not by way of limitation, specific preferred embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and that changes may be made without departing from the spirit and scope of the present invention.

(12) The retaining wall 10 described herein is formed as a modular structure that can be assembled from individual components, such as may be shipped on a truck to a site for installation. Referring to FIG. 1, the components forming the retaining wall 10 comprise elongated framing posts 12 forming a support structure or frame for supporting one or more wall panels 14. The framing post 12 includes or is connected to a side frame 16 that extends from a rear side 17 of the framing post 12. The side frame 16 includes a front end 16a at its connection to the framing post 12. A rear end 16b of the side frame 16, distal from the framing post 12, supports an anchor frame 18. The anchor frame 18 is configured to support an anchor panel 20, as is described in further detail below. The framing post 12, side frame 16, and anchor frame 18 form a framing post assembly 21.

(13) It should be understood that the side frame 16 and anchor frame 18 may be formed as a separate component, e.g., a separate poured component, that may be detachably bolted, or otherwise attached, onto a separately formed framing post 12, Alternatively, the side frame 16 and anchor frame 18 may be formed as separate components that can be detachably bolted, or otherwise attached, together and attached to a separately formed framing post 12.

(14) The retaining wall 10 includes at least first and second laterally spaced framing posts 12 that are preferably supported on a footer 19, and may contain any number of a plurality of framing posts 12 that are spaced laterally from one another. The framing posts 12 are configured to extend vertically and have a length that generally defines a height of the retaining wall 10, Each framing post 12 can comprise an outwardly facing front side 22 and opposing lateral edges defining elongated slot areas 24, 26. The slot areas 24, 26 extend the entire length, or substantially the entire length, of the framing posts 12. In the embodiment illustrated in FIGS. 1 and 2 the slot areas 24, 26 are defined as slots having a front side 12f and a rear side 12r connected by a central web 12c, i.e., comprising ‘closed’ slots, forming an I-beam configuration for the framing post 12, although other configurations of the slot areas may be provided, such as is described further below with reference to FIGS. 7 and 8.

(15) As seen in FIG. 1, the wall panels 14 are configurated to span laterally between adjacent framing posts 12 and include opposing lateral edges, or edge portions, 28, 30 sized to slidably fit within the elongated slot areas 24, 26. As seen in FIG. 2, the wall panels 14 may be formed with a height that is less than the height of the framing posts 12. Further, wall panels 14 having different heights may be provided for forming the retaining wall 10, as is illustrated by the different height wall panels 14a, 14b in FIGS. 1 and 2, wherein the differing height wall panels 14a, 14b may be alternately stacked on top of one another to form up a vertically extending section of the retaining wall 10.

(16) The side frame 16 can be formed integral with the framing post 12, or may be rigidly attached to the framing post 12, e.g., by bolting to the framing post 12, and can be formed as a generally quadrilateral structure having a lower side 31 that may be generally perpendicular to the framing post 12, and a declining upper side 32, extending downwardly toward the lower side 31 and rearwardly from the framing post 12. The side frame 16 can additionally include one or more support web members 33 extending between the lower and upper sides 31, 32. The anchor frame 18 can be supported at an angle relative to the framing post 12, i.e., at an angle relative to vertical, extending upwardly away from the framing post 12, i.e., extending upwardly from the lower side 31 toward the upper side 32. The anchor frame 18 includes opposing lateral edges defining elongated slot areas 34, 36 extending the entire length, or substantially the entire length, of the anchor frames 18. The slot areas 34, 36 may be defined as slots having a front side 18f and a rear side 18r connected by a central web 18c, i.e., comprising “closed” slots, forming an beam configuration for the anchor frame 18, see FIG. 1, although other configurations of the slot areas may be provided, as is described further below. The anchor panels 20 are configurated to span laterally between adjacent anchor frames 18 and include opposing lateral edges, or edge portions, 38, 40 sized to slidably fit within the elongated slot areas 34, 36. The anchor panels 20 may rest on a base 18b′ at the bottom of the slot areas 34, 36.

(17) Referring to FIG. 2, in assembling the retaining wall 10, a plurality of the framing post assemblies 21 can be positioned in laterally spaced relation on the footer 19. Wall panels 14 can be positioned within the spaces between the framing posts 12, e.g., between first and second framing posts 12, by engaging the lateral edge portions 28, 30 within the slot areas 24, 26 of the framing posts 12 at the upper ends of the framing posts 12 and sliding the wall panels 14 downward toward the footer 19. Similarly, the anchor panels 20 can be positioned within the spaces between the anchor frames 18 by engaging the lateral edge portions 38, 40 within the slot areas 34, 36 of the anchor frames 18, at upper ends of the anchor frames 18, and sliding the anchor panels 20 downward.

(18) It should be understood that a bin-like structure is defined by the side frames 16 and anchor panels 20, extending rearward from the frame portions 12 and wall panels 14, wherein the area within the bin-like structure can be filled with dirt or other fill material to form an anchor for preventing the assembled wall structure from tilting or tipping. In particular, the angled anchor panels 20 provide an outward angled surface for the weight of the filler material to apply a vertical force to resist forward tipping of the assembled wall structure. The rearward extending side frames 16 also resist rearward tipping of the assembled wall structure. Further, the outward angled configuration of the anchor panels 20 enables formation of a reduced excavation area behind the wall panels 14, i.e., by reducing the footprint or base area that needs to be excavated for receiving the rearward extending side frames 16, resulting in a reduced excavation cost to install the retaining wall 10.

(19) It should also be noted that the length of the side frames 16, extending rearward from the framing posts 12, can vary. For example, a selected length of the side frames 16 can be increased or decreased depending on the soil stability. Additionally, the length of the side frames 16 can vary in proportion to the height of the framing posts 12, wherein the length of the side frames 16 can increase or decrease with increasing or decreasing height, respectively, of the framing posts 12. Also, the height of the side frames 16 can increase with increasing length of the side frames 16 and/or increasing height of the framing posts 12. Hence, in providing the retaining wall 10 as a system for installation, the amount of excavation required for preparing a site for receiving the retaining wall 10 can be decreased as the height of the wall decreases.

(20) The retaining wall 10 described herein is not limited to a particular material for forming the components making up the assembled wall structure. For example, the framing post assemblies 21 may be formed as unitary concrete structures, such that fasteners may be substantially avoided in assembly of the retaining wall 10. In such an assembly, the wall panels 14 and/or the anchor panels 20 may also be formed of concrete or of another material. Further, the framing post assemblies 21, the wall panels 14 and the anchor panels 20 may be formed of other materials including, without limitation, steel and composite materials. Also, it may be understood that the components forming the retaining wall 10 need not be formed of the same materials, wherein the framing post assemblies 21 may be formed of one or more materials and the wall panels 14 and/or the anchor panels 20 may be formed of one or more different materials. Also, the framing post assemblies 21 may be formed of two or more different materials, wherein the framing post 12 and the side frame 16, and/or the anchor frame 18, may be formed of different materials such as, without limitation, two or more of concrete, steel, and a composite material.

(21) Exemplary alternative configurations for the retaining walls having different heights are illustrated in FIGS. 3-6.
