Definitions
- Concrete blocks have been used to create a wide variety of mortared and mortarless walls. These walls have been used in applications ranging from retaining walls for sloped areas, building construction, sound barriers, and other landscaping and structural applications. While blocks have primarily been valued for their ability to meet structural requirements, the demand for more attractive block products and walls is increasing.
- a concrete block has a face surface that is convergent toward a generally horizontal edge with respect to a plane extending vertically through the block, the face surface having a non-geometric pattern molded thereon, the face surface being configured such that no first point on said face surface is spaced further from said plane than any other point on said face surface positioned in a vertical line further from the generally horizontal edge than said first point.
- Another embodiment in accordance with the invention includes a mold box for forming concrete blocks in a high speed block machine.
- the mold box has an open top and bottom, opposed longitudinal side panels and opposed lateral end panels.
- There is a reciprocating shoe for reciprocatory up and down motion to engage a raw concrete mix within the mold box so as to configure a surface of the blocks as they are oriented within the mold box.
- a non-geometric pattern is embossed on at least one surface of the mold box, the surface being tapered so as to allow the block formed within the mold to disengage from the mold box.
- a method for the manufacture of concrete blocks having non-geometric patterns on their face surfaces is disclosed.
- the method includes providing a mold box having an open top and bottom, opposed longitudinal side panels and opposed lateral side panels.
- the mold box has a reciprocating top shoe for reciprocatory up and down motion to engage a raw concrete mix within the mold box so as to configure a surface of the blocks as they are oriented within the mold box and a divider plate for separating individual blocks within the mold box.
- the divider plate has opposed, outward facing surfaces that are downwardly convergent with respect to a vertical plane passing through the divider plate.
- Each convergent surface has a non-geometric pattern embossed thereon and each convergent surface is configured such that no first point on said surface is spaced further from said plane than any other point on said surface positioned directly vertically above said first point.
- the method further involves charging concrete into the open top of the mold box, and forcing the concrete into intimate contact with the convergent surfaces of the divider plate to form a molded block unit comprising two or more blocks.
- the mold box and divider plate are then vertically separated from the molded block unit with the block unit being spaced beneath the mold box and divider plate.
- a wall constructed of concrete blocks having various sizes and various patterns formed on their face surfaces includes a plurality of individual blocks stacked in an array of superimposed rows, with each block having at least one molded face surface with a non-geometric pattern formed thereon.
- the wall includes a first block having a first face surface with a length that is a multiple of an integer greater than one of the length of a second face of a second block.
- the wall also has a third block having a third face surface with a height that is a multiple of an integer greater than one of the height of a fourth face of a fourth block.
- the wall has blocks of various sizes and various face surface patterns distributed throughout the wall to create a non-uniform appearance.

- Figures 2, 3, and 4 are cross section views of the block shown in Figure 1, the cross sections views taken from the perspectives indicated at "A,” “B,” and “C,” respectively.
- the block 50 is generally rectangular in shape and has bottom 60, top 70, rear 80, two sides 90 and front 100.
- the bottom 60 and rear 80 surfaces of this embodiment are generally planar and arranged generally normal to one another.
- the sides 90 may be in normal arrangement to the front surface 100 when viewed from above or one or both may be angularly arranged thereto to allow for the construction of curved retaining walls.
- the side walls 90 are angled but the rear wall 80 extends beyond the intersection with the side walls 90 so that the rear wall is essentially the same length as the front face 100.
- the portions of the rear wall 80 that extends beyond the intersection of the rear wall 80 with the side walls 90 could be removed to allow for the construction of curved portions of retaining wall.
- the top 70 includes a first support area 110 defined over a predetermined area of the top for the support of additional blocks and a vertically extending shoulder 120 adjacent the front surface of the block.
- the embodiment includes a second top surface 130 at the uppermost end of the extending shoulder.
- the support area 110 and the vertical shoulder 120 provide a locating surface to receive an additional vertically positioned block on top of the block 50.
- the additional block may be positioned rearwardly from the front surface 100 of the receiving and supporting block whereby a wall of tiers of such blocks may extend rearwardly and upwardly from a support surface 110.
- Block 50 includes a front surface 100 that includes a rearwardly and upwardly directed face surface 10 and a lower generally vertical portion 140 generally normal to the bottom surface 60.
- the lower vertical portion 140 may be configured to interact with the vertical shoulder 120 of an additional block onto which the block is placed.
- there is no separate lower generally vertical portion and the face surface 10 of the block extends all of the way to the bottom surface 60 of the block 50.
- the face surface 100 could be rearwardly and downwardly directed so that the upper portion of the face surface 100 extended beyond the lower portion.
- the front surface 100 of block 50 includes a face surface 10 that has a non- geometric pattern 20 molded thereon.
- the block 50 has a face surface 10 that is convergent toward a generally horizontal edge 15 with respect to a plane V extending vertically through the block.
- the face surface 10 is configured such that no first point 30 on the face surface is spaced further from said plane than any other point 40 on said face surface 100 positioned in a vertical line further from the generally horizontal edge 15 than said first point 30.
- the face surface 100 converges upwardly, so no first point 30 on the face surface is spaced further from said plane than any other point 40 on said face surface positioned directly below said first point 30.
- Each vertical segment of the face surface 100 of the embodiment in Figure 1 is upwardly convergent so that the block may be formed in a high speed block machine and disengage from the mold box without significantly degrading the non-geometric pattern 20 on the face surface.
- Blocks could also be formed "upside down" in a high speed block machine so that the block as installed would have a face surface that is downwardly convergent with respect to a vertical plane.
- an intricate non-geometric pattern can be formed while keeping each vertical segment upwardly convergent as shown in Figures 2-4.
- a non-geometric pattern may be contrasted with a geometric pattern, which uses simple geometric forms like circles and squares.
- Such non-geometric patterns may include, but are not limited to, patterns resembling worn or hewn natural stone, patterns resembling layered or sedimentary stone, patterns resembling rugged stone, and others that are all contemplated within the scope of this disclosure.
- Blocks such as those shown in Figure 1 may be made of concrete that is a variegated mixture of concrete that is dyed or otherwise different in color.
- a non-homogeneous mixture of concrete of different colors may be injected into a mold to form blocks of essentially random colors and combinations of colors.
- the veining or dappling effect of the various colors of the concrete creates more interesting looking blocks.
- the walls formed from these collections of blocks, particularly if the collection contains blocks of various sizes, colors and color combinations, and face surface patterns, are more attractive and appealing in many applications than walls constructed of more uniform blocks.
- Figure 5 is a perspective view of a block in accordance with embodiments of the invention and a corresponding mold surface.
- the block 50 has a face surface 10 with a non-geometric pattern 20 molded thereon.
- the corresponding mold surface 155 is embossed with a non-geometric pattern 20 that is transferred to the block 50 during the block production process.
- the mold surface 155 of the embodiment shown in Figure 5 is a division plate 150 configured for installation in a mold box.
- the division plate is tapered at an angle T so that it is narrower at the bottom than the top.
- the mold surface 155 is configured such that each point on the mold surface is spaced farther from a vertical plane than any other point directly below the first point.
- FIG 6 is a perspective view of a division plate in accordance with embodiments of the invention.
- Figure 7 is a perspective view of the other side of the division plate of Figure 6.
- the division plate 150 has a non-geometric pattern 20 embossed thereon.
- the non-geometric pattern 20 on each side of the division plate is different, allowing for the production of two blocks with different non-geometric patterns at the same time.
- the division plate 150 is thicker at the top than at the bottom as described above, and the face surfaces of the division plate 150 are configured such that each point on the mold surface is spaced farther from a vertical plane than any other point directly below it. It may be advantageous to consider issues like plate thickness while designing the different non-geometric patterns on each side of the plate to ensure that the plate does not become too thin at a point where each face patter recedes.
- Figure 8 is a perspective view of a mold box in accordance with embodiments of the invention and a set of blocks that could be formed therein.
- the mold box of Figure 8 may be used for forming concrete blocks in a high speed block machine.
- the mold box 175 has an open top and bottom.
- the box 175 has opposed longitudinal side panels 160 and opposed lateral end panels 170.
- a reciprocating shoe 180 may engage a raw concrete mix within the mold box 175 so as to configure the top surface of the blocks as they are oriented within the mold box.
- This "top surface” may in fact be the a bottom or other surface as the blocks are ultimately oriented, and the reference to top only applies to the block as oriented within the mold box. The same applies to references to bottom and side surfaces.
- the mold box also includes a moveable planar base support 210 that acts as the bottom of the mold box to form blocks 50.
- the longitudinal side panels 160 of the embodiment of Figure 8 have optional core bar receiving openings 165 formed therein and an optional core bar 200 that may be reciprocally introduced and removed from the mold box 175 to configure a bottom surface of the blocks 50 as they are oriented in the mold box.
- blocks 50 may have a lower generally vertical portion 140 formed on the front surface.
- the core bar 200 is positioned within the mold box 175.
- the core bare 200 is then removed from the mold box 175 through the core bar opening 165.
- the blocks are then allowed to exit the mold box 175 through the bottom of the mold box.
- core bars 200 of various sizes may be used to create blocks 50 having different set backs for the generally vertical portion 140.
- the various set backs for the generally vertical portion 140 provide varied set-backs for individual blocks when the generally vertical portion 140 interacts with the vertical shoulder 120 of a lower block to provide a more interesting appearance to the wall.
- the core bar receiving openings 165 may be large enough to accommodate core bars 200 of various sizes so that blocks 50 having set backs for the generally vertical portion 140 of various depths may be formed using the same mold box 175, or different mold boxes 175 may be used with corresponding core bars 200.
- a non-geometric pattern 20 is embossed on at least one surface of the mold box, the surface being tapered so as to allow the block formed within the mold box 175 to disengage from the bottom of the mold box.
- the surface of the mold box that is embossed with a non-geometric pattern 20 is a divider plate 150.
- Each side of the divider plate 150 may have a different non-geometric pattern embossed thereon so that the blocks 50 formed in the mold box will each have a different non-geometric pattern molded on it.
- the longitudinal side panels 160 and/or the lateral end panels 170 may be embossed with a tapered non-geometric pattern 20 in addition to or instead of the divider plate 150.
- edges 190 of the shoe 180 adjacent to the surface of the mold box that is embossed with a non-geometric pattern is shaped to coincide with the upper edge of the surface of the mold box that is embossed, in this case the divider plate 150.
- the shoe may be configured with an irregular surface to better form the top surface (as oriented in the mold box) of the block 50 and then assist in the removal of the formed blocks from the mold.
- Figure 9 is a cross section of the mold box of Figure 8 as a set of blocks is being formed.
- Each block 50 is formed between the shoe 180, the planar base support 210, the divider plate 150, the longitudinal side panels 160 (not shown), and opposed lateral end panels 170.
- the optional core bar 200 forms a generally vertical portion 140 on the front face of the block. Once the blocks are formed, the core bar 200 is removed and the moveable planar base support 210 is lowered relative to the other elements of the mold box so that the blocks 50 slide out of the mold box.
- FIG. 10 is a perspective view of a mold box in accordance with embodiments of the invention and blocks formed from the mold box.
- a mold box 175 for forming concrete blocks 50 in a high speed block machine has an open top and bottom, opposed lateral side panels 160 and opposed longitudinal side panels 170.
- the assembly also includes a reciprocating top shoe 180 for reciprocatory up and down motion to engage a raw concrete mix so as to configure the top surface of the blocks 50 as they are oriented within the mold box.
- the assembly may also include a moveable planar base support 210 that acts as the bottom of the mold box as it is filled with concrete mix.
- the mold box may also include one or more divider plates 150 for separating blocks units within the mold box.
- the divider plate 150 may have a non-geometric pattern 20 embossed on it that will impress or emboss a non-geometric pattern 20 on the face surface 10 of the block 50.
- each side of the divider plate 150 has a different non- geometric pattern 20 embossed on it, providing the blocks 50 with a wider variety of face surface 10 appearances.
- the divider plate 150 is generally thicker at the top than at the bottom. This allows the formed block 50 to be removed from the bottom of the mold without the divider plate 150 marring the face surface 10 of the block. Even though the divider plate 150 is generally thicker at the top, a non-geometric pattern 20 may be embossed on the divider plate that has various contours and ridges. This can be accomplished by ensuring that each vertical segment of the divider plate 150 is always getting thicker as you move from the bottom to the top of the divider plate 150.
- each segment would generally get thicker as you move to the top of the divider plate, although different segments would get thicker at different points between the top and bottom of the divider plate 150.
- Each first point on the divider plate 150 is closer to the vertical center of the divider plate 150 than any point directly above that first point.
- the non-geometric pattern 20 formed on the face surface 10 may resemble a naturally occurring stone.
- inside surfaces of the longitudinal side panels 160 and lateral side panels 170 are also embossed with a non-geometric pattern 20.
- These side panels are also generally tapered to allow the block formed therein to be removed through the bottom of the mold and to disengage readily from the side panel without disturbing the pattern 10 embossed on the block 50.
- This embodiment also includes two divider plates 150, each with two sides that are embossed with a non- geometric pattern 20. All of these embossed surfaces may be embossed with different non-geometric patterns to provide a wide variety of face surfaces 10 to the blocks 50, all of which enhance the aesthetic appeal of walls constructed from such blocks.
- FIGS 11-16 show examples of other concrete blocks in accordance with embodiments of the invention. These blocks all have face surfaces with non-geometric patterns 20 formed thereon.
- Each of the generally vertical face surfaces 10 are tapered so that they converge toward a generally horizontal edge 15 with respect to a plane extending vertically through the block, the plane oriented parallel to the horizontal edge 15 edge of the face surface and behind the face surface.
- Each point on the generally vertical face surface 10 is spaced further from said plane than any other point on said face surface positioned in a vertical line further from the generally horizontal edge 15 than said first point.
- the block of Figure 11 is a freestanding landscape block.
- This embodiment has parallel load bearing surfaces 220, first and second ends 230, and first and second opposed face surfaces 10.
- the ends of this block are transverse to the load bearing surfaces 220 and the opposed face surfaces 10.
- the load bearing surfaces of the block have mating interlocks 240 comprising arcuate cores and protruding arcuate interlocks receivable in the cores.
- the interlocking cores are not vertically aligned with the protruding interlocks on the same building block.
- the block may be configured so that each end of a block comprises a half interlock and adjacent ends of a pair of blocks in a row together define an interlock portion that interlocks with a mating full interlock portion carried by a block in a vertically adjacent row of blocks.
- Blocks of this type are described more fully in U.S. Patent No. 6,948,282, entitled “Interlocking Building Block,” the relevant portions of which are hereby incorporate by reference.
- the block of Figure 12 is a freestanding landscape block usable as an end block in conjunction with the block of Figure 11.
- This block has parallel load bearing surfaces 220, an end 230, and first and second opposed face surfaces 10, and a third face surface 10 opposite end 230.
- the end of this block are comprises a half interlock 240 that interacts with an adjacent end of a block in a row to define an interlock portion that interlocks with a mating full interlock portion carried by a block in a vertically adjacent row of blocks.
- Blocks of this type are described more fully in U.S. Patent No. 6,948,282, the relevant portions of which are hereby incorporate by reference.
- the block of Figure 13 is a cap block for use with blocks such as the block of
- This block has a top face portion 35 with a non-geometric pattern 25 molded thereon.
- the top face 15 is formed by a reciprocating shoe so there are no limitations as to how the non-geometric pattern 25 is configured because the shoe lowers to mold the top face and raises away vertically to disengage the block.
- the front face 10 has a non- geometric pattern 20 molded thereon. This non-geometric pattern may be formed by a vertical mold surface and is configured such that each point of the face surface is closer to the rear wall 80 than any point directly below that point on the face surface 10.
- the block has a front wall 100 that includes the face surface 10 and a lower generally vertical portion 140.
- the lower vertical portion 140 may be configured to interact with the vertical shoulder 120 of an additional block 50 (Figure 1) onto which the block is placed.
- the block of Figure 14 is a block for use in creating structural walls without mortar.
- the block has opposed face surface 10 with a non-geometric pattern molded thereon.
- the generally horizontal surface 280 resembles a truncated cone when viewed from the end 300.
- the generally horizontal surface 260 is configured to interact with the surface 280 of an adjacent block by being angle inwardly so that the angled surface 250 will engage the angled surface 280 to form a stable wall of blocks.
- End 300 is recessed relative to the face surfaces 10 and end 310 extends beyond the face surfaces 10 so that adjacent blocks in a row of blocks interact end-to-end to increase wall stability. Blocks of this type are described more fully in U.S. Patent No. 6,082,067 entitled "Dry Stackable Block Structures," the relevant portions of which are hereby incorporated by reference.
- the block of Figure 15 is a retaining wall block that uses a pin and grove design to assist in stabilizing the wall.
- the block of Figure 15 has a face surface 10 with a non- geometric pattern 20 as described above.
- the side walls 320 taper rearwardly such that the rear wall 330 is shorter than the face surface 10.
- the passages 340 pass completely through the block and allow for the installation of pins through the blocks to aid in the stabilization of a wall constructed from the blocks. Blocks of this type are described more fully in U.S. Patent Application Pub. No. US 2006/0117697, entitled “Modular Block System,” the relevant portions of which are hereby incorporated by reference.
- the block of Figure 16 is a traditional concrete building block used on construction of concrete walls. This block is usable in mortared applications.
- the basic block is well known in the art, but the embodiment of Figure 16 has a non-geometric pattern 20 molded thereon that may be formed by a vertical mold surface and is configured such that each point of the face surface is closer to the longitudinal center line of the block than is any point directly above that point on the face surface 10.
- This embodiment of this block is formed upside down in a high speed block making machine.
- a block formed right side up would have a face surface 10 configured such that each point of the face surface is closer to the longitudinal center line of the block than is any point directly below that point on the face surface 10.
- Figure 17 is an elevation view of a collection of blocks in accordance with embodiments of the invention.
- the face surface 10 of each block is shown.
- the face surface 10 is a surface that will be visible when the block is installed in a wall. Other surfaces of the block may also be visible, but it is the face surface that is the predominant feature of the block once it is installed in a wall. Some blocks will have only one face surface, as in the main load bearing blocks of a retaining wall. Other blocks will have two or more face surfaces.
- a wall with two visible sides will be primarily constructed from blocks that have two face surfaces on opposite sides of the block.
- a block used at the end or top of a wall may have even more face surfaces, as will a block used to make a corner in the wall.
- Lw is an integer multiple greater than 1 of Ly and Lz. In this example, the integer is 2, meaning that the face surface 10 of the blocks W is twice as long as the face surface 10 of blocks Y and Z.
- Ly in this embodiment equals L A and is therefore also two times Lx and Lz. In other embodiments the integer could be 3 or greater. Also, in the collection of Figure 17, Hw equals Hx and the face surfaces of the W and X blocks are twice the height of the face surfaces 10 of the Y and Z blocks.
- the lengths and heights of the blocks in the collection are equal to each other or integer multiples greater than one of each other allows walls to be constructed with blocks of various sizes arranged in a variety of patterns because, for example, two blocks that are twice as long as a single other block of the collection, or three that are three times as long, may be used in lieu of a single block, and need not necessarily be adjacent to each other. If properly arranged, eventually the combination of blocks that are integer multiples of each other in height and length of face surface can form a uniform wall with a unique appearance.
- Blocks such as those shown in the collection of Figure 17 may also have a non- geometric pattern 20 molded thereon.
- this pattern 20 is formed by embossed elements of a mold box usable in a high speed block making machine.
- a collection of blocks may include several different patterns 20 on each block. Thus the variety of patterns and block sizes may combine to create an even more visually interesting wall design.
- Figure 18 is an elevation view of a wall in accordance with embodiments of the invention.
- the wall of Figure 18 combines the elements of various non-geometric patterns, block sizes, and block colors to create a visually pleasing non-manufactured looking concrete wall.
- the wall could also use various setback depths, to provide even more interest.
- the wall of Figure 18 could be constructed of blocks such as those described herein or any blocks known in the art that are amenable to the techniques taught and claimed in this application.
- Figure 18 demonstrates how a collection of blocks in accordance with the invention can be arranged to form a wall having interesting appeal with only four sizes of face surfaces 10 and a limited number of non-geometric patterns. Because the height and length of the face surfaces 10 of the blocks are either equal to the dimensions of adjacent blocks or multiples of integers greater than one of the length and/or the width of adjacent blocks, the collection of blocks can be used to create a pseudorandom looking wall while easily consuming a collection of blocks such as that in Figure 17. The resultant wall can be built to a variety of heights and can be used in a wide variety of applications.
- Figure 19 is an elevation view of a wall in accordance with embodiments of the invention.
- the wall of Figure 19 only includes one size of blocks, but still shows the interesting and appealing looks that can be achieved using a collection of blocks with non-geometric face patterns in accordance with the invention.
- Other arrangements of blocks of various sizes are contemplated by the inventors and will occur to those or ordinary skill upon reading this disclosure.
