Description

TECHNICAL FIELD

The present disclosure relates to retaining wall blocks, and more specifically to a retaining wall block having a false joint and a mold for manufacturing such.

BACKGROUND OF THE INVENTION

Retaining wall blocks can be manufactured and arranged in a variety of different ways.

SUMMARY OF THE INVENTION

A manufactured retaining wall block with an improved false joint and a system of retaining wall blocks with an improved false joint is presented herein.

In an embodiment, a retaining wall block having a false joint is presented. The retaining wall block comprises a body having a first surface and a second surface and a false joint dividing the first and second surface and extending a predetermined depth of the body.

DETAILED DESCRIPTION OF THE INVENTION

In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawing figures might or 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 example 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 body 102, a base 104, a top face 106, 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 FIGS. 1A and 1B, front face 115 includes a false joint 120. The false joint 120 can extend the width of the body 102 along the front face 115 and a depth of the body 102. The false joint 120 can be located anywhere along the front face 115 of the body 102 and can be extended to different depths of the body 102. As is more clearly shown in FIG. 1D, the false joint 120 can have an exterior false joint section having an apparent angle β and an interior false joint section having an apparent angle α. The false joint 120 can have an interior false joint width W and an interior false joint depth D and a depth divided by width (D/W) of greater than a predetermined amount, such as 2 to 3, depending on the size of the body 102, or other suitable amounts. The width W can be equal to or less than 3 mm or other suitable values. The false joint 120 can have a depth of about a third of the depth of the body 102, or other suitable depths. The apparent angle α of false joint 120 can range from less than 10° to greater than 20°, and the apparent angle β of false joint 120 can range from less than 60° to greater than 80°. A transition region between the interior false joint section and the exterior false joint section can have a thickness t, where t can be less than or equal to a predetermined value, such as 8 mm, or other suitable values. Furthermore, the body 102 can include multiple false joints 120. Alternate interior and exterior portions are shown as alternatives.

As shown in FIG. 1C, which is a side view of retaining wall block 100, retaining wall block 100 can also include a 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 engaged retaining wall blocks 100 and 200, in accordance with an example embodiment of the present disclosure. As shown in FIG. 2A, retaining wall blocks 100 and 200 can have different sizes and can include top faces 106 and 206, respectively, engagement cavities 110 and 210, respectively, and textured front faces 115 and 215, respectively. As previously discussed, retaining wall blocks 100 and 200 also include false joints 120 and 220, as shown in FIGS. 2A and 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 206 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 example 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.

FIG. 3 is a diagram of a retaining wall block 300 with false joints 120 formed in the molded product, prior to splitting, in accordance with an example embodiment. Block 300 includes a first block having a body 102 and base 104 casted with a second block having a body 102 and base 104. The individual blocks 100 can be formed by splitting block 300 at the centerline, through the diamond shaped aperture segmenting the false joints 120. Retaining wall block includes indentations 302-312. The false joints 120 described herein can be cast within the mold at different suitable depths and at different suitable widths, and at varying suitable locations within body 102 corresponding to selected false joint locations.

FIG. 4 is a diagram of a mold 400 for providing a false joint, in accordance with an example embodiment of the present disclosure. Mold 400 includes base 402, index notches 404, outer frame 406 and false joint 120 frame. When masonry compound or other suitable wet or dry mixes are added to the cavity of mold 400, false joint 120 frame creates a false joint feature, such as shown in FIG. 1D or other suitable false joints. After the block is formed by mold 400, mold 400 can be removed to allow the wet or dry mix to set and cure. False joint 120 frame can be coupled to mold 400 (not explicitly shown), or can be secured in another suitable manner to allow it to be withdrawn prior to setting.

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.
