Description

The present application claims the benefit of U.S. Provisional Application Ser. No. 60/569,221, filed May 7, 2004, which application is incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention relates to building materials, and in particular, construction blocks used to construct block structures such as buildings, walls, barriers, foundations, or the like.
Walls are often made of either concrete blocks or bricks. For example, some walls are made by digging a trench, pouring a concrete footing inside the trench, laying a first course of blocks onto the footing, and vertically stacking additional courses of concrete blocks on top of each other, and using mortar in between blocks to attach the blocks to each other. Steel rods (e.g. steel reinforcing bar known as rebar) may be inserted vertically through hollow interiors of the concrete blocks and horizontally between courses of the blocks for structural support, and the hollow interiors of the blocks may be filled with concrete for greater strength.
Some walls have a lay of bricks over plain concrete blocks to form a facade to improve the appearance of the wall. The bricks are individually laid by hand with the use of mortar or adhesives known in the art. The process of brick laying is time consuming, labor intensive, and requires additional materials (e.g., bricks and mortar). A faster and less labor-intensive system for creating the impression of a brick facade is desired.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a method for constructing a block wall having the appearance of a brick facade. The method includes providing a plurality of concrete blocks. Each of the blocks includes a front wall, a rear wall, a left sidewall, and a right side wall. The front wall has an exposed front face and the rear wall has an exposed rear face. The method includes forming at least one groove on at least one of the faces of each of the blocks, or providing blocks having grooves on at least one of the faces of each of the blocks. The concrete blocks are attached to each other to form a block structure. The faces of the plurality of concrete blocks preferably form a facade, and the grooves on each of the blocks provide an impression that the facade comprises a plurality of bricks.
In accordance with one aspect of the invention, there is provided a block for construction of a block structure, for example, a block wall or the like. The block includes a front wall having a front face, a rear wall having a rear face, a left sidewall having a left face, and a right sidewall having a right face. At least one of the faces includes at least one groove, the grooves are configured to provide an impression that the block structure is constructed from a plurality of smaller blocks, for example, bricks.

DETAILED DESCRIPTION OF THE INVENTION

The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.
A right front perspective view of a building block 20 according to the present invention is shown in FIG. 1A, and a front view of the building block 20 is shown in FIG. 1B. A multiplicity of the building block 20 may be used to construct block structures, for example, buildings, walls, barriers, foundations, and the like. The building block 20 includes a front wall 22, a rear wall 24, a left sidewall 26, and a right side wall 28. Walls 22, 24, 26, and 28 preferably define a hollow interior 30. The hollow interior 30 is preferably divided into two sections by an interior wall 32 which is attached substantially perpendicularly to the front wall 22 and rear wall 24. The interior wall 32 is preferably positioned substantially centrally between the right side wall 28 and the left sidewall 26. The front wall 22 has a front face 22 a, the rear wall 24 has a rear face 24 a, the left sidewall 26 has a left face 26 a, and the right sidewall 28 has a right face 28 a. A rebar notch 31 may be provided in tops of the walls 26, 28, and 30 to allow a horizontal run of rebar to tie columns of the blocks 20 together. The notches 30 are preferably large enough to allow the rebar to be surrounded by concrete and/or mortar for added strength. Typically, horizontal rebar runs are vertically spaced apart at, for example three feet, and preferably two horizontal runs of rebar are used in a wall.
With continuing reference to FIGS. 1A and 1B, the building block 20 includes at least one groove on the front face 22 a to provide an impression of more then one smaller block. In one embodiment, the front face 22 a of building block 20 preferably includes a plurality of vertical grooves 34 a-34 e and a plurality of horizontal grooves 36 a and 36 b creating raised surfaces between the grooves. The grooves 34 a-34 e and 36 a and 36 b are preferably arranged in a manner that gives an impression that the building block 20 is made of a plurality of smaller blocks (i.e., small than the blocks 20), for example bricks individually attached to each other, and that a structure constructed form the block 20 provides an impression of a brick facade, and the grooves 34 a-34 e and 36 a and 36 b are preferably straight grooves.
The block 20 is may be made from a pre-designed mold that creates the grooves 34 a-34 e and 36 a-36 b on at least the front face 22 a, and additionally may create the grooves on the rear face 24 and/or the left face 26 a and/or the right face 28 a of the building block 20. Concrete may be poured into the mold, dried, and the resulting block 20 removed from the mold. Colored concrete material known in the art may be poured into the mold to produce a colored brick imitation. For instance, a rusty red colored concrete material may be used to form rusty red building block.
Alternatively, the building block 20 may be made from existing concrete blocks having plain faces. A cutting or grinding tool suitable for use with concrete may be used to cut or grind the grooves on the faces 22 a, 24 a, 26 a, and/or 28 a. The faces 22 a, 24 a, 26 a, and/or 28 a may be painted (before or after creating the grooves) with a desired color, and the grooves may be painted with a color different from the color used on the faces to provide a visual effect. Preferably, the block 20 may be molded, or cut/ground from a plain block, creating raised surface having approximately the dimensions of bricks on the front face 22 a of each of the blocks 20.
The block 20 is preferably made in approximately one or more of several common sizes, for example, 14 inches by 8 inches by 8 inches, 16 inches by 8 inches by 8 inches, 14 inches by 6 inches by 8 inches, 16 inches by 6 inches by 8 inches, 8 inches by 8 inches by 8 inches, 8 inches by 6 inches by 8 inches, 12 inches by 12 inches by 2 inches, and 12 inches by 6 inches by 2 inches. The raised surfaces (i.e., the face portions separated by the grooves in FIGS. 1A, 1B, and 2) are preferably approximately the size of a common brick, for example, approximately 2¼ inches by approximately eight inches.
The spatial orientations of the grooves on the faces 22 a, 24 a, 26 a, and/or 28 a and number of grooves may be varied and still fall within the scope of the present invention. For instance, in a second embodiment of the block 20 a is shown in FIG. 2, the number and the orientations of the vertical grooves have been modified from the number and orientations of the vertical grooves 34 a-34 e of the embodiment shown in FIGS. 1A and 1B. Specifically, the number of vertical grooves has been reduced by one and they are arranged so that one groove 35 a is substantially on the center of the first row 37, two grooves 35 b and 35 c are on the second row 39, and one groove 35 d is substantially in the center of the third row 41.
With reference to FIG. 3, a third embodiment of the block 20 b is shown. The front wall of building block 20 b preferably includes two vertically oriented grooves 42 a and 42 b. Each groove 42 a or 42 b preferably spans from the top of front wall 46 to the bottom of the front wall 48. Grooves 42 a and 42 b are preferably substantially equally spaced apart from each other to define three columns 47, 48, and 49.
With reference to FIG. 4, a fourth embodiment of block 20 c is shown wherein the building block 20 b of FIG. 3 is modified to include additional horizontal grooves 72 and 74, which are preferably positioned substantially in the middle of column 47 and 49, respectively. With reference now to FIG. 5, a fifth embodiment of building block 20 d is shown. The front face 22 a of building block 20 c includes a first row 52, a second row 54, and third row 56. The first row 52 preferably has a vertical groove 58 approximately centered on the row 52. The second row 54 preferably includes three rectangular protrusions 60, 62, and 64 having approximately the same width. The third row 56 has a vertical groove 60 approximately centered on the row 56.
Referring to FIG. 6, a sixth embodiment of building block 20 e is shown wherein two equally spaced horizontal grooves 82 and 84 span across the front wall of the building block. Grooves 82 and 84 preferably define three rows 86, 88, and 90 on the front face 22 a of the building block 20 e. With reference to FIG. 7, a seventh embodiment of building block 20 f is shown wherein two equally spaced vertical grooves 102 and 104 are added to the building block embodiment 80 shown in FIG. 6. Vertical grooves 102 and 104 define columns 106, 108, and 110 on the front face 22 a of building block 20 f. The front face 22 a of building block 20 f shows a total of nine brick-like structures 112 a-l.
Referring to FIG. 8, an eighth embodiment of building block 20 g is shown wherein a design 114 a, 114 b, and 114 c replaces the brick like structures 112 d, 112 e, and 112 f in FIG. 7. The block 20 g thus provides the impression of a decorative row between rows (or courses) of bricks. While diamond shaped designs are shown in FIG. 8, a block with top and bottom rows creating the impression of bricks or of smaller blocks, and a center row having one or more designs, is intended to come within the scope of the present invention.
The front face of a block 20 h similar to the block 20 (see FIG. 1A, 1B) is shown in FIG. 9. The block 20 h includes half width groove 34 f and 34 g which cooperate in adjacent blocks to give the appearance of a single full width groove. The half groove 34 f and 34 g reside at ends of rows corresponding to ends of full size brick likenesses.
While FIGS. 1-9 show blocks with grooves in the front face 22 a, a block with grooves in the rear face 24 a and either or both end faces 26 a and 28 a are intended to come within the scope of the present invention. Further, a block with grooves in any combination of faces 22 a, 24 a, 26 a, and/or 28 a are intended to come within the scope of the present invention.
A clip 120 is shown in a perspective view in FIG. 10A and in an end view in FIG. 10B. The clip 120 is used to hold adjacent blocks 20 closely together during construction to better provide the appearance of a brick facade.
