Definitions

  • the invention relates to concrete blocks, such as wet cast or dry cast concrete blocks for use in the creation of walls, including blocks having an embossed front face. More particularly, the invention relates to concrete blocks with natural stone appearance for use in the creation of curved walls, such as retaining walls.
  • Concrete blocks are well known for the use in landscaping applications, particularly retaining walls.
  • Various different block configurations or shapes are known.
  • concrete retaining wall blocks are usually provided with a rearwardly tapered body with sidewalls that are at an angle of less than 90 degrees to the front face of the block.
  • Stacking such blocks side by side with the angled sidewalls of adjacent blocks engaging one another results in a convexly curved wall.
  • Concave curvatures are obtained by stacking the blocks side by side with the front edges touching, while the tapered rear ends are spaced apart. This provides significant flexibility in the creation of curved walls the radius of curvature of the wall being limited solely by the angle of the sidewalls relative to the front face.
  • tapered blocks and walls built with such blocks have several drawbacks.
  • Straight walls built with stacked blocks of tapered shape have a substantially continuous front face, but include a pattern of multiple gaps in the back face of the wall, due to the angled sidewalls.
  • even curved walls with a curvature less than the maximum convex curvature allowed by the taper of the blocks will always include this pattern of gaps. Consequently, tapered blocks cannot be used to build freestanding walls, since the appearance of the rear wall will be very different from the front face and will not be aesthetically pleasing due to the pattern of gaps.
  • a freestanding wall with natural appearance on both sides is not achievable with tapered blocks.
  • a wall block system for building freestanding curved walls is desired, wherein all sides are continuous and have a natural stone appearance.
  • the retaining capacity of a retaining wall is determined in part by the mass of the wall.
  • the gaps formed in the rear surface of walls made with tapered blocks significantly reduce the overall mass of the wall.
  • a wall blocks system for freestanding curved walls is desired, which maximizes the mass of the wall and minimizes any gaps between laterally adjacent wall blocks.
  • Molding dry cast tapered blocks with converging side walls and an embossed front face is challenging due to the need for stripping the compressed block from the mold.
  • Dry casting uses a no slope concrete mixture which is filled into a mold cavity and compressed to sufficiently pre-consolidate the block to permit handling of the block prior to curing of the concrete mixture.
  • the block is stripped from the mold and transported to a curing station for curing of the concrete mixture. Stripping of the block is achieved by pushing it out of the mold with a stripper shoe which has a dual function.
  • the stripper shoe is used during pre-consolidation to compress the dry cast concrete mixture.
  • the stripper shoe is used for forcing the pre-consolidated block from the mold.
  • the stripper shoe is provided on its dry cast mixture engaging face with a negative of the three-dimensional surface structure to be produced on the block face during pre-consolidation.
  • the embossed blocks are usually manufactured with the front and rear faces oriented up and down in the mold, respectively. That means the sidewalls of the mold must be movable from the angled position required for the shaping of the tapered shape of the block, in order to provide a clear path of the block through the mold. It is also possible to cast a block assembly consisting of a support block connectable with a face block as disclosed in US2007/0292216 . Thus, embossed wall blocks for the assembly of curved walls are desired which are more easily manufactured.
  • the invention provides a stackable concrete wall block, having a prism shaped body with front and rear faces, in a stacked orientation, top and bottom faces for placement opposite like blocks positioned above and below in a stacked condition of the wall block and at least a pair of side walls for placement opposite a like block placed side by side to the wall block, and a lip protruding from at least one of the sidewalls and coplanar with the front face for spacing the body of the block from the body of a like block placed adjacent thereto.
  • the lateral lip comprises multiple staggered steps, each step defined by two perpendicular walls respectively parallel to the side walls and the rear face of the block.
  • the front face of the block and the lip have an embossed three-dimensional surface structure.
  • the block is preferably a dry cast, embossed concrete block.
  • the lip is preferably provided on one or both of the side walls to create lateral spacing between concrete blocks stacked side by side in a wall, while providing the wall with a continuous front face. As is the case with tapered blocks, this spacing allows the assembly of curved walls. However, a prism shaped block with straight side walls and a lip is more easily manufactured than a tapered block with angled side walls, since no movable mold walls are required, when the block is a dry cast block.
  • the lip can be achieved by way of a draw plate which is placed in the mold for filling and compression of the dry cast mixture and is pulled from the mold cavity prior to stripping.
  • draw plates in the manufacture of dry cast concrete blocks is known, but is generally used for the production of three-dimensional structures and/or undercuts on the rear face of the block.
  • the lip preferably has a depth which is at the maximum 50% of the overall depth of the block as measured from the front face to the back face and preferably between 5% and 50%, most preferably between 25% and 50%.
  • the dry cast concrete block further includes a connecting structure for connection of a secondary structure, such as a setback pin, a like concrete block, a veneer block, or a filler block to the rear face of the concrete block.
  • Filler blocks are used for covering any rearward gap created in an installed condition by the lip between the block and an adjacent like block.
  • a back to back attachment of a pair of like blocks by way of the connecting structure allows for the assembly of a two sided wall.
  • the connecting structure is preferably a dovetail type connection with one or more female connector members provided in a back surface of the wall block and a corresponding number of complementary male connector members provided on the secondary structure to be connected to the back surface.
  • the invention provides a set of dry cast concrete blocks including a wall block, a filler block and a connecting structure for connecting the wall and filler blocks in a back-to-back arrangement.
  • the wall block preferably has a prism shaped body with front and rear faces, in a stacked orientation, top and bottom faces for placement opposite like blocks positioned above and below in a stacked condition of the wall block and at least a pair of side walls for placement opposite a like block placed side by side to the wall block, and a lip protruding from at least one of the sidewalls and coplanar with the front face for spacing the body of the block from the body of a like block placed adjacent thereto.
  • the front face of the block and the lip have a three-dimensional surface structure
  • the filler block has a prism shaped body with generally front, rear, top and bottom faces and generally parallel side walls.
  • the wall and filler blocks may have a different height.
  • the wall block has a depth A and the filler block has a depth C and the overall width of the filler block is between X and X-n(Y+YC/A-B).
  • the wall and filler blocks may have a different height.
  • the connecting structure is preferably in the form of a dovetail type connection with one or more male connector members provided on one of the wall and filler blocks and a corresponding number of female connector members provided on the other of the wall and filler block.
  • the connecting structure may be a separate connector insertable into complementary recesses in the wall and filler blocks.
  • any other connecting structure can be used, which is incorporated into or separate from one or both of the wall and filler blocks, as long as the connecting structure renders the wall and filler blocks connectable in a back-to-back orientation.
  • the present application is directed to a wall block for use in retaining walls or freestanding walls, preferably a cast concrete block, more preferably a dry cast, embossed concrete block.
  • the wall block 100 includes, a prism shaped body 110 with a front face 112, a rear face 114, top and bottom faces 116 and 118 and generally parallel side walls 119.
  • the wall block 100 further includes a protruding lip 120 on at least one of the side walls 119, which lip 120 protrudes from the side wall 119 and is coplanar with the front face 112.
  • the lip 120 can be provided on either one or both of the side walls 119. The spacing created by the lips 120 allows the assembly of straight walls as shown in Fig. 1 or curved walls as shown in Fig.
  • the protruding length of the lips 120 determines the radius of curvature which can be achieved by placement of the wall blocks 100 side by side in wall with the lips 120 and the bodies 110 of adjacent blocks touching (see Figs. 5-7 ).
  • the larger the protruding width of the lips the smaller the minimum radius achievable.
  • the shorter the length of the wall block 100 the smaller the minimum radius achievable.
  • the lip 120 provides for spacing between the bodies 110 of adjacent wall blocks 100 placed side by side, while providing the resulting wall with a continuous front surface, as shown in Fig. 1 .
  • the front face 112 of the block which extends over the lip 120, preferably has an embossed three-dimensional surface structure.
  • the front face 112 is embossed with a surface structure, which provides the wall block 100 and any wall assembled with such wall blocks with the appearance of natural stone. This feature will be described in more detail further below with reference to Figs. 10-13 .
  • the lip 120 can be provided on either one or both of the side walls 119, preferably both, to create bi-lateral spacing between the bodies 110 of wall blocks 100 stacked side by side in a straight wall (see Fig. 1 ), while providing the wall with a continuous front surface. As is the case with tapered blocks, this spacing allows the assembly of curved walls, by arranging the wall blocks in such a way that terminal edges of the front and rear faces 112, 114 of adjacent wall blocks 100 are in engagement (see Fig. 2 ).
  • a wall block 100 with a prism shaped body 110 with parallel side walls 119 is more easily manufactured by dry casting than known, tapered blocks, since no movable mold walls are required.
  • the dry cast wall block 100 further includes a connecting structure 300 for connection of a secondary structure to the rear face 114 of the wall block 100.
  • the secondary structure can be a setback pin, a like block, a different block, or a veneer.
  • the different block is preferably a filler block 200 as shown in Figs. 3 and 4 for covering any rearward gap created in an installed condition by the lip between the block and an adjacent like block.
  • the connecting structure 300 includes at least one pair of interconnecting protruding and recessed elements, most preferably in the shape of a dovetail arrangement (see Figs. 3-8 ), one of the elements being incorporated into the rear face 114 of the wall block 100 and the other one into the secondary structure.
  • the connecting structure preferably includes multiple alternating protruding and recessed elements 310, 320 in the shape of a repeated dovetail arrangement as shown in Figs. 3 and 4 .
  • the filler block 200 is provided for covering any rearward gap created by the lip 120 between the wall block 100 and an adjacent like block 100 in the installed condition.
  • the length of the filler block must be less than the length of the wall block (see Figs. 3 and 5-7 ), while in a straight configuration the filler block must have the same length as the wall block (see Figs. 4 and 8 ).
  • the filler block 200 includes a prism shaped body 210 with a front face 212, a rear face 214, top and bottom faces 216 and 218 and generally parallel side walls 219.
  • the filler block 200 further includes a connecting structure 330 which interlocks with the connecting structure 300 on the wall block 100 for connection of the filler block to the rear face 114 of the wall block 100.
  • the connecting structures 300 and 330 are preferably of complementary shape in order to provide for an interlocking of the wall and filler blocks 100, 200.
  • a set of dry cast concrete blocks including a wall block 100 and a filler block 200.
  • the wall block 100 has a prism shaped body 110 with an embossed front face 112 and generally planar rear, top and bottom faces 114, 116, 118 and generally parallel side walls 119, and a protruding lip 120 extending from at least one of the sidewalls and coplanar with the front face 112 for spacing the body 110 of the wall block 100 from the body of a like block placed adjacent thereto, while providing a continuous front surface.
  • the front face 112 of the wall block 100 and the lip 120 have a three-dimensional surface structure embossed into the front surface by the stripper shoe in the dry cast molding process.
  • the three dimensional structure preferably provides the wall block with a front face 112 having the appearance of natural stone.
  • the filler block 200 has a body 210 shaped as a rectangular prism and having a front face 212, a rear face 214, top and bottom faces 216, 218 and generally parallel side walls 219.
  • the filler block 200 preferably has a three-dimensional surface structure embossed into the front surface 212 by the stripper shoe in the dry cast molding process.
  • the three dimensional structure preferably provides the filler block 200 with a front face 212 having the appearance of natural stone.
  • the wall block 100 further includes a connecting structure 300 and the filler block 200 of the set of blocks includes a connecting structure 330 for connecting the wall and filler blocks in a back-to-back arrangement.
  • a pair of interconnected wall and filler blocks 100, 200 is illustrated in each of Figs. 3 and 4 .
  • the interconnecting structure 300 and 330 is a series of dovetail shaped protrusions 310, 340 alternating with dovetail shaped recesses 320, 350 in the respective rear faces 114 and 214 of the wall and filler blocks 100, 200.
  • the dovetail shaped connectors on the respective rear faces are offset so that a protrusion 310 in the rear face 114 of the wall block 100 engages a recess 350 in the rear face 214 of the filler block 200 and a connector 340 in the rear face 214 of the filler block 200 engages a recess 320 in the rear face 114 in the wall block 100.
  • the protruding length Y of the lips 120 determines the radius of curvature which can be achieved by placement of the wall blocks 100 side by side in a wall with the lips 120 and the bodies 110 of adjacent blocks 100 being in engagement.
  • An angle a is enclosed by the side wall 119 of the wall block 100 and an imaginary line 400 connecting the free end 121 of the protruding lip 120 with the terminal edge 115 of the rear wall 114. This angle is the minimum angle at which adjacent wall blocks can be placed without forming a gap between the blocks at the front face 112.
  • wall blocks 100 can also be placed side by side in straight alignment to form a straight wall, in which case the protruding lips 120 are in engagement, but the blocks do not touch at the rear face 114, resulting in a space between adjacent wall blocks 100 at the rear face 114.
  • filler blocks 200 are used which have the same overall width X as the wall blocks 100, as shown in Figs. 4 and 8 .
  • the wall blocks 100 are placed side by side with the lips 120 in engagement, while the lateral edges 115 of the rear faces 114 are placed closer to one another as in the straight orientation.
  • the lateral edges 115 of the rear faces 114 of adjacent blocks 100 are in engagement and the blocks are placed at the angle a relative to one another.
  • the width of the filler blocks 200 must then be adapted to fit within the imaginary lines 400 defined on each side of the associated wall block 100 by the angle a, as illustrated in Fig. 4 .
  • the overall width of the filler block 200 then not only depends on the angle a, but also on the depth C of the filler block 200, since the larger the depth, the shorter the overall length required for the block fitting between the imaginary lines 400.
  • Casting of the lip 120 can be achieved by way of a draw plate 140 (see schematically in Fig. 9b ), which is placed in the mold for the wall block.
  • the draw plate is left in the mold for the filling of the mold and compression of the dry cast mixture in the mold and is pulled from the mold cavity prior to stripping of the block.
  • the use of draw plates in the manufacture of dry cast concrete blocks is known.
  • the lip 120 preferably has a depth B, measured in a direction parallel to the associated side wall 119, which is a maximum of 50%, preferably between 50% and 5%, most preferably between 50% and 25% of the overall depth A of the wall block 100 as measured from the front face 112 to the back face 114 (see Fig. 3 ).
  • the larger the depth of the lip 120 the wider a gap 117 between the front faces 112 of adjacent stacked blocks 100 in a curved wall.
  • the smaller the depth of the lip 120 the harder it is to manufacture the block 100 by dry casting, since the lip 120 may brake or sag during or after demolding and prior to complete setting of the block.
  • the minimum radius achievable with stacked blocks 100 including the lip 120 is determined by the protruding length Y, or overhang, of the lip 120, which is the distance the lip 120 protrudes laterally outward from the sidewall 119 of the block 100.
  • the larger the overhang created by the lip 120 the smaller the minimum radius achievable.
  • the larger the overhang the higher the risk of the lip 120 braking or sagging during or after demolding. Consequently, the range of radius achievable by adding a single lip 120 on each side of the block 100 is limited.
  • the invention also provides variant of the block 100 in which a larger total protruding length Y or overhang is achieved by providing a stepped lip 120 including two or more steps 120a, 120b, as illustrated in Figs. 10a to 10d .
  • a stepped lip 120 including two or more steps 120a, 120b, as illustrated in Figs. 10a to 10d .
  • the protruding length of each step is preferably the same and equal to the total protruding length of the lip divided by the number of steps.
  • the outermost step is coplanar with the front face. Any additional step is located further back towards the rear face 114 and provides a setback or undercut, so that the overall width of the block becomes progressively more narrow with each additional step.
  • the depth of the outermost step adjacent the front face 112 is preferably larger than the depth of any subsequent step.
  • the protruding length of the outermost step is preferably smaller than the protruding length of any subsequent step.
  • the protruding length of the outermost step is preferably less than half the protruding length of the subsequent step.
  • the block 100 in one embodiment includes an irregularly shaped front portion 190 and a regularly shaped rear portion 195, the front portion including the embossed front face 112 with an irregularly shaped contour 112a with lateral edges 113.
  • the block of Figure 10a further includes an interconnecting structure 300 for the connection of a secondary structure (not shown), such as a setback pin, a like concrete block, a veneer block, or a filler block, to the rear face 114 of the concrete block.
  • the connecting structure is preferably a dovetail type connection with one or more female connector members 350 provided in a back surface of the wall block and a corresponding number of complementary male connector members provided on the secondary structure to be connected to the back surface 114.
  • Filler blocks when attached by way of the interconnecting structure 300 can be used for covering any rearward gap created in an installed condition by the lips 120a, 120b between the block and an adjacent like block.
  • a back to back attachment of a pair of like blocks by way of the interconnecting structure 300 also allows for the assembly of a two sided free standing wall.
  • the wall and filler blocks may have a different height.
  • the wall and filler blocks may have the same or different heights.

  • any other connecting structure can be used, which is incorporated into or separate from one or both of the wall and filler blocks, as long as the connecting structure renders the wall and filler blocks connectable in a back-to-back orientation.
  • the block 100 is provided with an embossed front face 112, which includes at least one false joint 180, which may extend at an angle to the top and bottom faces 116, 118.
  • the false joint extends at an angle of about 45 degrees to the top and bottom faces, but other orientations of the false joint at any angle from 0 to 45 degrees are possible.
  • the front face can include multiple false joints respectively oriented at different angles to the top and bottom faces.
  • the block 100 or 100a can also be provided with irregularly shaped front faces 112 where at least one lateral edge 113 of the front face extends at an angle of up to 45 degrees to the side wall 119.
  • the lateral edges 113 of the front face are oriented at an angle of 0 to 45 degrees to the sidewall in order to give the block the appearance of a natural stone.
  • One or both of the sidewalls 119 can also be oriented at an angle other than perpendicular to the top and bottom faces 116, 118, for example at an angle of 70 to 110 degrees to the top or bottom face.
  • the angled sides of the block be limited to only a front portion 190 of the block, with a rear portion 195 of the block having parallel sidewalls 119 perpendicular to the top and bottom faces 116, 118, for maximum stability of a wall of stacked like blocks.
  • the blocks 100 with multiple steps 120a, 120b can also be used to build curved wall, whereby the radius of the curvature achievable is determined by the combined protruding length of all the lips 120a, 120b at each end of the block.
