- a block 10 is formed (e.g., molded) to include an elongated center portion 12 with a pair of side walls 14, 16 arranged at either end of the center portion, and substantially perpendicular thereto.
- the block will be described as having a front and a back, top and bottom but it will be appreciated that these terms are relative, and are not intended to be limiting in any respect.
- the block 10 may be regarded as a top, left, front perspective view, with Figures 2-5 described relative to Figure 1. Accordingly, the reference to "top”, “bottom”, “front”, “back”, “left” and “right” refers to the block in Figure 1, with its tt front" side facing forward. It will be understood, however, that adjacent upper and lower blocks are reversed and inverted on assembly, so that the characterization of the block with reference to Figure 1 is for convenience only.
- the center portion 12 of the block has a flat, substantially vertical back wall 18 and a sloped front wall 20.
- the back wall 18 is flush or co-planar with back (or first) edges 22, 24 of the side walls 14, 16, respectively.
- the sloped front wall 20 extends between a relatively thicker bottom wall or base 26 to a relatively thinner top wall 28, the acute slope angle preferably in the range of about 45-90° (shown at 71.3 'in Figure 5) relative to the horizontal bottom wall or base 26.
- the terms “thicker” and “thinner” in this context relate to the depth dimension of the block.
- the side walls 14, 16 extend beyond, i.e., forward of, the sloped front wall 20, and the relatively thinner top wall 28 extends above the upper (or second) edges 30, 32 of the side walls.
- Lower (or third) edges 30a and 32a of the sidewalls are flush with the bottom wall or base 26.
- a horizontal shoulder 34 extends horizontally across the sloped front wall 20 at a height substantially equal to the height of the side walls, such that shoulder 34 lies in the same horizontal plane as the upper edges 30, 32 of the side walls 14, 16.
- surface 34 could be regarded as the top surface of the block, contiguous with upper edges 30, 32, and with a truncated triangular lip
- the block 10 may have a length ⁇ from side to side) of between about 190 mm and 460 mm (for example about 395 mm) and a depth (from front to back) of between about 80 mm and 200 mm (for example, about 92 mm) .
- the total height of the block (from bottom to top) may be between about 80 mm and 240 mm (for example, about 124 mm) .
- the lip 33 extends about 32 mm. above the side walls 30, 32 (and surface 34) .
- the side wall thickness may be about 38.5 mm.
- the center portion 12 may have a depth of about 59.9 mm. at the base 26, (in this embodiment, the forward (or fourth edges) 22a, 24a of the side walls 14, 16 are forward of the center portion), and a depth of about 12 mm. at the top edge 28.
- the lip 33 may have a depth of about 6mm. (or, stated otherwise, the lip 33 is set back from the forward edge
- the block may vary uniformly by scale, or differentially, depending on specific applications . It will also be appreciated that the block may be constructed of any suitable building materials including in addition to concrete, such materials as metals, plastics, resins, etc.
- a wall unit ⁇ or simply, wall 40 may be constructed of plural blocks 10 stacked one on top of the other, but with alternate blocks inverted and reversed, i.e., rotated 180° (front to back) as shown in Figures 6-9.
- the front, back, top and bottom edges of blocks 10 in one horizontal row A of blocks in a vertically-stacked array become the back, front, bottom and rear edges, respectively, of the next adjacent horizontal row B of blocks.
- the load-bearing surfaces are the top and bottom edges 30, 32 and 30a, 32a, respectively (see Figures 1-5) , of the engaged side walls 14, 16 of adjacent blocks.
- each inverted block 10 is vertically spaced from the base 26 of the next adjacent block, leaving a forward facing slot or aperture 36 on the forward (exterior) face 38 of the wall 40, and a rearward slot or aperture 42 on the rearward (interior) face 44 of the wall, connected by an upwardly and rearwardly sloping air flow passage 46 formed by adjacent sloped walls 20 of adjacent pairs of stacked blocks.
- the forward-facing aperture 36 is vertically spaced from the rearward-facing aperture 42, so that there is no line of sight from one side of the wall unit to the other.
- the upwardly sloped passage 46 also prevents rain, even horizontal rain caused by excessive wind, from passing through the wall.
- the wall 40 has the three-fold advantage of ventilation, privacy and rain protection. It will be appreciated that the size of any individual wall unit 40 is application- dependent, but a unit made up of only two blocks is within the scope of this invention,
- a mold assembly 48 designed especially for the block 10 may include a core 50, an outside division plate 54, an inside division plate 52, and a pair of end liners (not shown) bolted together in a mold box (also not shown) .
- the plunger 56 and stripper shoe assembly 58 are bolted together and attached to a stripper head plate (not shown) that enables the plunger 56 and stripper shoe assembly 58 to move down into the mold box.
- the core 50 and stripper shoe assembly 58 are specially shaped to provide the sloped wall 28 and horizontal shoulder 34.
- the stripper shoe assembly includes the stripper bar 58A and a pair of blocks 58B.
- the bar 58A and blocks 58B are . adapted to be bolted to the bottom of the plunger 56 in the orientation shown in Figures 10 and 11, with a vertical space between the bar 58A and blocks 58B for receiving a portion of the core 50 as described below.
- the core 50 includes a laterally extending, vertically-oriented plate portion 60, including bolting flanges 61, and a core block portion 62.
- sloped surface 64 on the core block portion 62 ( Figure 10) and the continuation of that surface via the interior sloped surface 66 on the stripper shoe component 58A, best seen in Figures 11-13, enable formation of the sloped surface 20 and the lip 33 of the block 10, extending between the side walls 14, 16.
- the lower edge 68 enables formation of shoulder 34.
- a pallet plate (not shown) is moved into position below the mold box, and concrete is poured into the box.
- the mold box is ⁇ vibrated to settle and uniformly distribute the concrete, and then the plunger 56 and stripper shoe 58 are moved into the box to compress the concrete while under vibration, within the confines of the inner and outer divider plates 52, 54, end liners (not shown) and about the core 50.
- the block 10 is stripped from the mold by removing the pallet, enabling the stripper shoe and plunger to push the finished product out of the mold box.
- the sloped center portion may be flat as shown in Figs. 1-5 or concave (when facing as shown in Figure 1), and may extend at its base or bottom wall to a point behind the forward edges 22a, 24a of the side walls 14, 16 as shown in Figs. 1-5, or may be substantially flush with the forward edges 22a, 24a of the side walls.
- the horizontal shoulder 34 may be omitted, with a simple transition between the sloped surface and the extended lip 33.
- the front face of the lip and the sloped center portion could be co-planar .
- a vertical center wall may be interposed between the side walls, extending parallel thereto, with a gap between the adjacent lip portions. This arrangement is especially suited for wider blocks where the center wall will provide additional strength.
