DETAILED DESCRIPTION

[0032] The present invention can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this invention is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

[0033] The following description of the invention is provided as an enabling teaching of the invention in its best, currently known embodiment. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the invention described herein, while still obtaining the beneficial results of the present invention. It will also be apparent that some of the desired benefits of the present invention can be obtained by selecting some of the features of the present invention without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the present invention are possible and can even be desirable in certain circumstances and are a part of the present invention. Thus, the following description is provided as illustrative of the principles of the present invention and not in limitation thereof.

[0034] As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a beam member” can include two or more such beam members unless the context indicates otherwise.

[0035] Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

[0036] As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

[0037] The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list.

[0038] The word “substantially” as used herein can be used to define an angular tolerance of +/−15 degrees with respect to a disclosed (e.g., desired) angular relationship between two geometric entities. For example, “substantially vertical” can indicate that a reference surface or body is oriented vertically or within +/−15 degrees of absolute vertical alignment. Similarly, “substantially collinear” can indicate that two bodies can are collinear or positioned within an alignment divergence of +/−15 degrees of a collinear orientation (with the second body having an angular orientation relative to the first body that is less than or equal to 15 degrees and greater than or equal to −15 degrees).

[0039] In the following description, the orientation of the components of the disclosed building elements, retaining walls, and wall systems can be described with reference to a series of axes, including a first axis 114, a second axis 116 that is perpendicular to the first axis, and a third axis 118 that is perpendicular to the first and second axes. A primary plane can be defined by and contain the first axis and the second axis. A secondary plane can be defined by and contain the second axis and the third axis. A tertiary plane can defined by and contain the first axis and the third axis.

[0040] In various aspects, described herein with reference to FIGS. 1-22 are building elements 100, 100A, 1006, 100C, 100D, 100E that are configured to be assembled together with at least one other building element to form a retaining wall 300. In these aspects, the building elements can comprise a face panel defining a front surface and a rear surface oriented on an opposing side of the face panel from the front surface. It is contemplated that the face panel can comprise a length dimension oriented along the first axis 114 and a height dimension oriented along the third axis 118. In additional aspects, and as further disclosed herein, the building elements can further comprise at least one beam member coupled to the rear surface of the face panel. Each beam member can have an upper surface and a lower surface. The beam member can comprise a height dimension oriented along the third axis 118 and a length dimension oriented along the second axis 116. Optionally, in exemplary aspects, at least one surface of the upper surface and the lower surface of at least one beam member can define an alignment void as further disclosed herein.

[0041] FIGS. 1-6 depict examples of a building element 100A that can be used to form at least a portion of a retaining wall 300. In an aspect, building element 100A can comprise a face panel 102 and at least one beam member 104. To provide a framing structure for a retaining wall, the face panel 102 can be coupled or secured to the beam member 104. Optionally, in exemplary aspects, a portion of each beam member 104 can be permanently secured to or integrally formed with a corresponding face panel 102. In an aspect, the face panel 102 can comprise a front surface 102A and a rear surface 1026. The front surface 102A and the rear surface 1026 can be defined on opposing sides of the face panel 102.

[0042] As depicted in FIG. 1, the face panel 102 can comprise a rectangular surface comprising a length dimension, which can extend along the first axis 114. The face panel 102 can further comprise a width/thickness dimension, which can extend along the second axis 116. The face panel 102 can still further comprise a height dimension, which can extend along the third axis 118. In a further aspect, the face panel can be oriented at an angle with respect to the primary plane, which contains and is defined by the first axis 114 and the second axis 116. Optionally, in this aspect, the face panel 102 can be perpendicular or substantially perpendicular to the primary plane (and the second axis 116). That is, the face panel 102 can be oriented vertically or substantially vertically (approximately 90 degrees) with respect to the primary plane defined by the first and second axes 114, 116 (and parallel or substantially parallel with respect to the third axis 118). In general, the primary plane will be approximately level and can be parallel or substantially parallel to a ground surface on which the retaining wall is erected. In a further aspect, at least a portion of the rectangular surface of the face panel 102 can be coplanar or substantially coplanar with the secondary plane, which contains and is defined by the first axis 114 and the third axis 118.

[0043] Although generally described herein as having a flat, rectangular construction, it is contemplated that at least a portion of the face panel 102 can have a radius of curvature that defines an arcuate profile (e.g., a convex or concave profile). For example, the face panel can bow with respect to an arcuate path determined by the associated radius.

[0044] In another optional configuration, and as shown in FIGS. 1-6, the face panel 102 can also comprise at least one projection 120 extending outwardly from one of a top surface 102C or a bottom surface 102D of the face panel. Additionally, or alternatively, as shown in FIG. 12, the face panel 102 can define at least one inwardly recessed notch or slot 112A. In exemplary aspects, the face panel can comprise a plurality of projections 120 extending outwardly from the top surface 102C and a plurality of notches or slots 112A defined within the bottom surface 102D of the face panel 102. Additionally, or alternatively, the face panel can comprise a plurality of projections 120 extending outwardly from the bottom surface 102D and a plurality of notches or slots 112A defined within the top surface 102C of the face panel 102. In use, each notch or slot 112A can be configured to receive a corresponding projection of an adjacent face panel (upper or lower) when a retaining wall 300 is constructed as disclosed herein. Optionally, when the top or bottom surfaces 102C, 102D of the face panel 102 comprise both projections 120 and notches or slots 112A, it is contemplated that each slot of the face panel can be axially spaced from each projection of the face panel relative to the first axis 114.

[0045] In use, it is contemplated that the projections 120 and notches or slots 112A can be used as engagement features to further stabilize the face panel 102. For example, engaging the face panels 102 of respective panels during retaining wall construction can reduce movement of the face panels along the second axis 116. Optionally, it is contemplated that the projections 120 can be oriented perpendicularly or substantially perpendicularly to the first plane (and extend parallel or substantially parallel relative to the third axis 118). In a further aspect, a portion of the top or bottom surface of the face panel can be coplanar of the first plane comprising the first axis 114 and the second axis 116. Optionally, in exemplary aspects, and as shown in FIG. 1, the projections 120 can comprise a base surface 120B coupled to the top surface 102C or bottom surface 102D of the panel 102 and an apex or apex surface 120A that is spaced outwardly from the base surface 120B relative to the third axis 118. For example, it is contemplated that the projection 120 can optionally comprise a pyramid or dome type structure, with the apex 120A corresponding to the minimal diameter portion of the projection and the base surface 120B corresponding to the maximal diameter portion of the projection. In yet another example, the projection 120 can define an apex surface 120A as opposed to a true apex, such as a tip. In this example, it is contemplated that a variety of shapes for the projection are possible, including, for example and without limitation, a rhomboid shape, a conical frustum, a rectangular prism, a cylinder, and the like. During the construction of a face panel 102 comprising a projection 120 or a notch or slot that is configured to receive a projection, a mold can be formed to have a corresponding indentation that defines a projection 120 in one or more surfaces of a face panel as disclosed herein. Similarly, it is contemplated that the mold can define a projection or protrusion that is configured to form a notch a slot in one or more surfaces of a face panel as disclosed herein. In use, the projection 120 can be configured to increase the stability of the retaining wall when building elements 100 are stacked upon each other. For example, in another aspect, as shown in FIG. 13, a notch, slot, or other alignment void 112 can be defined by a top surface 102C or bottom surface 102D of the face panel 102, and each alignment void 112 can be configured to receive a corresponding projection 120 as disclosed herein.

[0046] As discussed earlier, the building element 100 can comprise a beam member 104, which can comprise a length dimension oriented along the second axis 116, a width dimension oriented along the first axis 114, and a height dimension oriented along the third axis 118. In exemplary aspects, the beam member 104 can comprise a brace section 106 that is mechanically coupled or secured to the rear surface 1026 of the face panel 102. Optionally, it is contemplated that at least a portion of the beam member can be integrally formed with the face panel 102. In further aspects, the beam member 104 can comprise a back section 108 that has a length dimension along the first axis 114 such that it is perpendicular or substantially perpendicular to the brace section 106. Optionally, it is contemplated that the back section 108 can be integrally formed with a rear portion of the brace section 106. Alternatively, it is contemplated that the brace section 106 and the back section 108 can be formed separately and mechanically coupled or attached.

[0047] Optionally, as shown in FIGS. 1-2, it is contemplated that the back section 108 can have a trapezoidal cross-sectional shape, although alternative shapes are possible. In general, the length dimension of the brace section 106 and length dimension of the back section 108 are perpendicular with respect to one another to provide stability and balance. In an aspect, the back section 108 can have a length dimension ranging from about 4 ft. to about 30 ft., from about 6 ft. to about 20 ft., or from about 7 ft. to about 10 ft. Optionally, the back section can have a length dimension of about 8 ft. It is further contemplated that the dimensions of the face panel 102, beam member 104 and back section 108 can further vary to accommodate the mode of transportation. More particularly, it is contemplated that the length dimensions of the face panel 102, beam member 104, and back section 108 can be selected to maximize efficiency in shipment or transport. For example, during shipment of building elements 100 on a tractor trailer with a towing bed length of 50 to 55 feet, it is contemplated that the length dimensions of the face panel 102, the beam member 104, and the back section 108 can be selected such that the length dimension of the beam member does not exceed the width of the towing bed and the length dimensions of the face panel 102 and the back section 108 are sufficiently small that the towing bed can accommodate at least two building elements along its length.

[0048] As depicted in FIG. 1, a top surface of the brace section 106 extends higher along the third axis 118 than the top surface of the back section 108. In addition, the trapezoidal cross section of the back section 108 can comprise a back surface 109 oriented at an angle relative to the third axis 118. In a further aspect, this back surface 109 can be coplanar or substantially coplanar with a rear surface 106C of the beam member. The angled orientation of surfaces 109 and 106C, in addition to the top surface of the back section 108, can define an engagement surface for engagement with the extension element 200 depicted in FIG. 8 and further described herein.

[0049] Referring to FIGS. 3-6, the length dimension of the back section 108 can be divided at a coupling junction 111 positioned at the intersection of the back section and the brace section 106. As depicted, it is contemplated that the back portion 108 can be asymmetric relative to the coupling junction 111, with unequal lengths of the back portion positioned on opposing sides of the coupling junction. Alternatively, the back portion 108 can be symmetric relative to the coupling junction 111, with equal or substantially equal lengths of the back portion positioned on opposing sides of the coupling junction. The symmetry or asymmetry of the back section 108 relative to the coupling junction 111 can be adjusted to account for variations in the underlying earth. Similarly, it is contemplated that the front panel of each building element can either be symmetric or asymmetric relative to the junction between the beam member and the front panel.

[0050] In an aspect, the beam member 104 can have a length dimension ranging from about 3 ft. to about 14 ft., from about 4 ft. to about 12 ft., or from about 5 ft. to about 10 ft. Optionally, the beam member can have a length dimension of about 8 ft. In an aspect, the beam member 104 can have a height dimension ranging from about 3 ft. to about 9 ft., from about 4 ft. to about 8 ft., or from about 5 ft. to about 7 ft. Optionally, the beam member 104 can have a height dimension of about 6 ft. In a further aspect, the beam member 104 can have a width dimension ranging from about 3 in. to about 9 in., from about 4 in to about 8 in., or from about 5 in. to about 7 in. Optionally, the beam member 104 can have a width of about 6 in.

[0051] In various aspects, and with reference to FIGS. 3-6, each building element 100 can further comprise at least one reinforcement wing 110. In these aspects, each reinforcement wing 110 can comprise a member that strengthens the coupling between the beam member 104 and either the face panel 102 or the back portion 108. Functionally, the reinforcement wing 110 can increase structural integrity of the building element 100 by preventing the face panel 102 or the back portion 108 from being bent by internal earth load pressures. Structurally, a reinforcement wing 110 can be operably coupled or secured to the rear surface 1026 of the face panel 102 and a side surface of the brace section 106 of the beam member 104. Similarly, it is contemplated that a reinforcement wing 110 can be operably coupled or secured to a front surface of back portion 108 and a side surface of the brace section 106 of the beam member. In exemplary aspects, reinforcement wings can be provided in pairs, with a first reinforcement wing 110 positioned on a first side of the beam 104 relative to first axis 114 and a second reinforcement wing 110 positioned on a second, opposite side of the beam relative to the first axis, thereby providing additional stability. For example, the at least one reinforcement wing can comprise a first pair of reinforcement wings that extend, respectively, from opposite sides of the beam 104 to contact portions of the face panel 102 or the back portion 108 that are positioned on opposing sides of the beam relative to the first axis 114. Optionally, it is contemplated that the at least one reinforcement wing 110 can comprise first and second pairs of reinforcement wings, with a first pair of reinforcement wings extending, respectively, from opposite sides of the beam 104 to contact portions of the face panel 102 that are positioned on opposing sides of the beam relative to the first axis 114, and with a second pair of reinforcement wings extending, respectively, from opposite sides of the beam 104 to contact portions of the back portion 108 that are positioned on opposing sides of the beam relative to the first axis 114.

[0052] In exemplary aspects, it is contemplated that the reinforcement wings of each pair of reinforcement wings can be symmetrical relative to the beam 104. However, in other exemplary aspects and as shown in FIGS. 3-6, it is contemplated that the reinforcement wings of each pair of reinforcement wings can be asymmetrical relative to the beam 104. In various aspects, it is contemplated that each reinforcement wing 110 can have a width dimension relative to the first axis 114 and a length dimension relative to the second axis 116. Optionally, in these aspects, the reinforcement wings of a pair of reinforcement wings can have different width dimensions while maintaining substantially equal length dimensions. In further exemplary aspects, when the reinforcement wings of a pair of reinforcement wings have curved or arcuate side surfaces that define a curve or arc within the primary plane, it is contemplated that each side surface can have a respective radius of curvature. Optionally, in these aspects, the side surfaces of the reinforcement wings of the pair of reinforcement wings can have an equal radius of curvature; alternatively, in asymmetrical configurations, it is contemplated that the side surfaces of the reinforcement wings can have different radii of curvature.

[0053] Optionally, each reinforcement wing can have a triangular shape; however, other geometric shapes are possible. For example, as shown in FIGS. 1 and 2, the reinforcement wings 110 extending between the beam 104 and the face panel 102 can have an arcuate profile with a variable cross-sectional area relative to the third axis 118, such as an arcuate profile including a curved or arcuate side surface (e.g., a concave side surface) and a curved or arcuate upper surface (e.g., a concave upper surface), which can optionally extend upwardly from the side surface and taper inwardly until reaching the top surfaces of the face panel and the beam at the junction between the face panel and the beam. In other examples, it is contemplated that the reinforcement wings 110 can define planar upper and lower surfaces and have a side surface that extends between the upper and lower surfaces and has either a straight orientation or a curved or arcuate orientation. In another aspect, as shown in FIGS. 7 and 9, each reinforcement wing can comprise a triangular prism that extends along the height dimension of the beam and has a uniform cross sectional area along the third axis 118. As shown in FIGS. 4-6, the respective top views of the reinforcement wings 110 demonstrate a variety of triangular or arcuate profiles that can be used. In a further aspect, when a side surface of a reinforcement member extending from the beam to the back portion has a straight orientation (defining a reinforcement member with a generally triangular shape), it is contemplated that the side surface can define an angle A relative to first axis 114. Similarly, when a side surface of a reinforcement member extending from the beam to the face panel has a straight orientation (defining a reinforcement member with a generally triangular shape), it is contemplated that the side surface can define an angle B relative to first axis 114. For example, the angle A or B of reinforcement wings 110 can range between about 30 degrees and about 75 degrees, between about 45 degrees and about 60 degrees, or between about 50 degrees and about 55 degrees.

[0056] In erecting a retaining wall, it is contemplated that the modularity provided by the detachable portions of the brace section can provide increased variability in the length dimension of the beam member 104 and provide a builder with additional flexibility in building element configurations to account for variations in the earth. In exemplary aspects, as shown in FIGS. 12 and 15, the first and second portions 106A, 1066 of a brace section 106 can be securely attached to each other using at least one alignment post or securing rod 126 (optionally, a plurality of securing rods) as disclosed herein. Optionally, in these aspects, a front portion of the second portion 1066 of the brace section 106 can be configured to overlie a rear portion of the first portion 106A of the brace section to permit attachment of the second portion to the first portion. For example, as shown in FIGS. 1-2 and 12, the first portion 106A can have a variable height moving along the second axis 116, with the first portion having a rear portion with a reduced height that defines a recess for receiving and engaging the front portion of the second portion 106B, which in turn can define a complementary recess that receives the rear portion of the first portion. When engaged together, the first and second portions 106A, 106B can cooperate to define a brace section 106 having a consistent height relative to the third axis 118. Optionally, an upper surface of the rear portion of the first portion 106A can define at least one alignment void 1126 that is configured to receive a portion of an alignment post or securing rod 126 that extends downwardly from the front portion of the second portion 1066. In exemplary aspects, a plurality of securing rods 126 can span between the first and second portions 106A, 106B.

In a further aspect, a reinforcement bar 169 can be embedded within the second portion 106B of the brace section 106 and coupled to the securing rods 126. The reinforcement bar 169 can increase the alignment and stability of the securing rods when the securing rods 126 are engaged to alignment voids 1126 located at the joint 107 between the brace sections 106A, 1066.

Building Elements Having Beam Members that Define Horizontal Apertures

[0057] In another aspect, as depicted in FIG. 7, a surface of the brace section 106 can define an aperture 124 that surrounds an axis that is parallel to the first axis 114. The aperture 124 can be used as a conduit to allow backfill comprising filler materials to pass through the beam member and allow for more consistent filling during erection of the wall. In exemplary non-limiting aspects, the aperture can have a cross-sectional area ranging from about 1 sq. ft. to about 10 sq. ft., from about 2 sq. ft. to about 9 sq. ft. or from about 3 sq. ft. to about 8 sq. ft. Optionally, the cross sectional area can be about 5 sq. ft. The aperture 124 can also reduce cost and weight of the building element by reducing the amount of concrete needed to form the respective elements. The aperture can further provide additional engagement features to allow a crane or moving apparatus to grab the building element for transport. During erection of the wall, the apertures 124 can serve as conduits to pass utilities or communications lines and also allow for movement of workers among different sections of the wall assembly before filler materials have been delivered. The filler materials 166 can comprise earthen materials such as dirt, sand, gravel, rocks, sand, or the like. In use, the apertures 124 can help the building element maintain consistent contact with the filler material 166, thereby providing increased stability.

[0064] As shown in FIG. 10, in a further aspect, the cap 142 can be strengthened using reinforcement material 149 such as a metal or plastic material embedded within the setting material. During erection of a retaining wall system, the alignment post 122 can be placed in the alignment void 112 defined by a surface of a respective beam member of a building element 100. As the stem 140 is set within the alignment void 112 of the respective beam member 104 the cap 142 will be the portion of the alignment post 122 protruding away from the surface of the beam 104.

[0065] In an alternative aspect, the stem 140 can comprise multiple materials. For example, an outer layer that circumscribes the stem axis 148 can comprise a plastic material such as polyethylene. An inner material for the stem 148 can be a metal bar that serves as a reinforcement of the plastic outer layer.

Securing Rods

[0066] FIG. 9 depicts another exemplary embodiment of a building element 100C, which comprises a securing rod 126 extending away from a top or bottom surface 102C, 102D of the building element.

As shown in FIG. 16, the securing rod 126 as well as the alignment void 112 can be configured to be engaged as further disclosed herein such that a plurality of building elements 100C can be stacked upon each other. Again, the engagement between the securing rod 126 (and alignment posts) and their corresponding alignment voids 112 can allow the building element 100C to have increased stability by securing a connection between the two respective building elements. In a further aspect, building element 100C can serve as the top building element in a retaining wall as further disclosed herein. In a further aspect, the height dimension of the face panel 102 is less than the height dimension of the beam member 104.

Retaining Wall Systems

[0067] As shown in FIG. 12, depicts a side view of building element 100A. As further disclosed herein, the brace section can be detachable into first portion 106A and second portion 106B. In a further aspect, the first portion 106A can be coupled (e.g., secured) to the face panel 102 and the second portion 1066 can be detachably coupled to the first portion at a joint 107. In a further aspect, as disclosed herein, the first portion 106A and the second portion 106B can be coupled using securing rods 126. For example, a securing rod 126 can be a dowel, pin, or piece of rebar that is inserted to properly align the first and second portions 106A, 1066 of the brace section of the beam member 104. In another exemplary aspect, the upper surfaces of the first and second portions 106A, 1066 can define respective slots or recesses (alignment voids) that are configured to receive opposing end portions of a U-bar 150 as shown in FIG. 12. In this aspect, the respective alignment voids can be axially spaced relative to the second axis 116.

[0068] FIGS. 13-15 depict an exemplary retaining wall 300 structure comprising a plurality of building elements. In an aspect, the retaining wall can comprise a combination of various types of building elements disclosed herein. It is contemplated that the retaining walls 300 can comprise a combination of one or more building elements 100A-E and/or an extension element 200 as disclosed herein. In a further aspect, as shown in FIG. 15, upon assembly of a plurality of building elements 100A as disclosed herein to form a retaining wall, it is contemplated that the joints 107 of adjacent building elements 100A are not vertically aligned. Optionally, in some exemplary aspects, it is contemplated that no joint 107 of any building element 100A will be vertically aligned with the joint 107 of any other building element 100A. For example, the joints 107 that occur at the intersection between the first and second portions 106A, 1066 of the brace sections can be offset by at least 1 foot along the second axis 116. Offsetting the joint 107 across different layers of the wall can produce a staggered configuration that reduces the stress points in the wall. In a further aspect, staggering the joint 107 locations can reduce the potential of a fault line that runs through the layers of the wall. As also depicted, alignment voids can be located at different sections of the beam member 104 and face panel 102 to insure that the variable configurations of the building elements can still be secured together. As depicted, the top layer of a retaining wall can comprise a building element 100C.

[0069] As shown in FIG. 16, the securing rod 126 as well as the alignment void 112 can be configured to be engaged such that a plurality of building elements 100C can be stacked upon each other. Again, the combination of engagement between the securing rod 126 and alignment notches 120 with the alignment void 112 allows the building elements 100 to have increased stability by securing a connection between the two respective building elements. In a further aspect, building element 100C can serve as the top building element in a retaining wall. In a further aspect, the height dimension of the face panel 102 is less than the height dimension of the beam member 104.

[0070] An additional aspect adding to the versatility of building elements 100A-E is that they can be produced from a single mold. During the casting of a building element, a manufacturer can transition between respective building elements by adjusting the internal molding structure (e.g., by filling in receptacles or emptying receptacles to modify the shape to be created by the mold). The adjustments to the internal molding structure allow alternate components of a building element to be formed with a differing shape or orientation.

[0071] Although generally described herein as having a substantially vertical orientation, it is contemplated that the retaining walls produced as disclosed herein can have any desired orientation relative to the a horizontal plane, including for example and without limitation, a wall batter producing an angular orientation ranging from about 70 degrees to about 90 degrees relative to the horizontal plane.

In a further aspect, the securing bracket 154 can be attached to the rear surface 102B.

Spacers

[0074] In an alternative aspect, as depicted in FIG. 21, two building elements can be oriented in a wall without being physically coupled (i.e., the spacers are not mechanically fixed in any way to the building elements). For example, a spacer 160 can be used to maintain a space 162 between two respective face panels 102. For example, the space 162 allows building elements 100 to settle independently in a vertical or substantially vertical orientation without touching each other. The size of the space may be evaluated based on any determined irregularities in the settlement of backfill. During erection, the spacer 160 can be covered with a geotextile fabric to prevent erosion. In as aspect, the spacer 160 can comprise weather resisting materials such as roof shingles, slate rocks, galvanized stretch metal pieces covered with geotextile fabric. The spacer can also be placed on the rear surface 1026 that faces the earth (filler material) 166. In a further aspect, the space 162 can range from about 0.25 in. to about 4 in., from about 1.5 in. to about 3.0 in, or from about 2.0 in. to about 2.5 in. Optionally, the space 162 can be about 2.5 in. In exemplary aspects, the spacer can have a dimension relative to the first axis 114 that is at least 2 to 3 times the size of space 162. In operation, the spacer 160 can provide a cantilevering function to the front panels toward the open joint, with the spacer cooperating with the common fill behind the panels to provide tolerance and stability in case of an earthquake or irregular settlement.

[0075] It is contemplated that the spacer 160 can work with any combination of building elements disclosed herein.

Joint Stiffeners

[0076] In an aspect of the retaining wall, a joint 163 between face panels 102 can be strengthened using a joint stiffener 164 as depicted in FIG. 22. In a further aspect, the joint stiffener 164 can be oriented along the height dimension of the face panel 102 along the third axis 118. To facilitate the insert of the circular joint stiffener 164, the surfaces along the third axis 118 of the face panel 102 can define a semicircular channel 102E. It also further contemplates that the joint stiffener can have another geometric cross sectional shape. Similarly, the surface of the face panel can define a channel that mates with the alternative geometric cross sectional shape.
