Description
- 1. Field of the Invention
- The present invention relates to retaining walls, and more particularly, but not by way of limitation, to retaining wall blocks specifically formed to be of light weight construction, and methods of their manufacture.
- 2. History of Related Art
- Retaining walls having been used in general construction, and particularly in landscaping for many years. The design of and the materials used for retaining walls have varied over time. Retaining walls are typically used to support or retain soil or the like in place, but also may be used to enhance the appearance of a surrounding area. Such walls typically stand on a ground region and retain therebehind an earthen section or other fill material, which earthen section would otherwise form a natural slope in place of the retaining wall. Such retaining walls are typically vertical, or at a slight angle. A generally retaining wall may begin to deform as the mass of the earth retained behind it presses against it. A wall must resist this tendency. In addition, designers of retaining walls are constantly striving to construct retaining walls providing greater strength for support of a greater weight.
- One of the most popular, and aesthetically pleasing forms of retaining wall construction involves the use of manually positionable individual blocks. The blocks may be stacked one on top of the other to form a pattern on an outside face of the retaining wall. It can be very time consuming and tedious aligning numerous blocks to form the proper pattern in the retaining wall. Moreover, a retaining wall may have one or more curved portions. The very design of many retaining wall blocks encompasses the exposed face which may be curved or flat. Irrespective of the shape of the face of the block, the weight of the block is of tantamount importance. Various approaches have been taken in retaining wall block design to reduce weight.

- It would be a distinct advantage to have a block which is simple to make and to use in building retaining walls, and which provides lighter weight, while maintaining the aesthetic beauty of the face of the block once in place in a retaining wall.
- The present invention relates to retaining walls, and more particularly, one aspect of the present invention involves a retaining wall block. The retaining wall block includes an underside recessed surface for reducing the weight of the block while allowing the face of the block to be formed with any desired shape.
- In another embodiment, the block of the present invention may have an arcuately formed underside which reduces weight of the block. The face may be curved. The block may also include at least one aligning element located on a surface of the block body. When assembling the blocks on top of each other, the blocks are staggered, so that each block in an upper row rests upon parts of two blocks in a lower row.
- A more complete understanding of the method and apparatus of the present will become more apparent by reference to the following drawings, in conjunction with the accompanying Detailed Description.
-
FIG. 1 is a perspective view of a first embodiment of a retaining wall block constructed in accordance with the principles of a first embodiment of the present invention; -
FIG. 2 is a side elevational view illustrating the block inFIG. 1 ; -
FIGS. 3A and 3B are perspective and side-elevational views of an alternative embodiment of the retaining wall block, constructed in accordance with the principles of the present invention; and -
FIG. 4 is a flow diagram of a method according to an embodiment of the present invention. - The present invention relates to a retaining wall system incorporating retaining wall blocks of lighter weight construction and a method of manufacture of the lighter weight wall blocks. Other retaining wall systems incorporated in patent applications filed by the inventor of the present invention are PCT/US00/03677 entitled “Interlocking Segmental Retaining Wall”, U.S. Pat. No. 6,464,432 entitled “Interlocking Segmental Retaining Wall”, and PCT/US03/01583 entitled “Interlocking Retaining Wall Blocks and System” and are incorporated herein by reference.
- Referring now to
FIG. 1 , there is shown a perspective view of theretaining wall block 10 of the present invention. The retainingwall block 10 includes a roundedfront face 12, although arcuate and geometrical shapes may be included. Therear wall 14 ofblock 10 includes anupstanding lip 16 for purposes of securing theblock 10 relative to other blocks. Fromrear wall 14, theside walls 18 and 20 taper outwardly to thefront face 12. Thesolid block 10 is also constructed with anintermediate area 22 of reduced thickness. In the present embodiment,intermediate area 22 is formed of a generally arcuate shape allowing thesolid block 10 to be fabricated with less weight. - Still referring to
FIG. 1 , it should be noted that theblock 10, as depicted herein, is in an inverted position. The block would be positioned with thelip 16 facing downwardly to engage an underlying row of blocks in a retaining wall. - Referring now to
FIG. 2 , there is shown a side elevational cross sectional view of theretaining wall block 10 ofFIG. 1 . It may be seen that theintermediate area 22 has a sufficient depth for removing substantial portions of the concrete therefrom to allow reduction in weight. - Referring now to
FIGS. 3A and 3B , there are shown perspective and side-elevational views of one alternative embodiment of theretaining wall block 100. As will be seen inFIGS. 3A and 3B , theblock 100 is formed with a planarfrontal surface 102 and has thearcuate recess 222 formed therebehind for purposes of reducing the weight thereof. Other retaining block shapes are also contemplated in accordance with the principles of the present invention which include the reduction in the weight of block in an area of the block not affecting the structural integrity nor the appearance thereof once the block is assembled in a retaining wall. It should specifically be noted that theintermediate area 22 ofFIGS. 1 and 2 andarcuate recess 222 ofFIGS. 3A and 3B may be of a variety of shapes other than the arcuate form shown herein. The side walls may also taper outwardly or inwardly, whereby the surfaces of the top and bottom of the blocks have much greater or much less surface area differential. In this manner, the back wall of the block may be tapered and/or constructed with varying shapes and contours. - Referring now to
FIG. 4 , amethod 400 according to an embodiment of the present invention is illustrated. Atstep 402, a retaining wall block is formed with an upper surface and a lower surface. Atstep 404, a cavity is formed along at least a portion of the lower surface of the retaining wall block. The recessed cavity reduces the weight of the wall block while maintaining the integrity of the front face of the wall block. The recessed cavity may be formed in a wall block with a variety of front face geometries such as a curved or planar front face. Other aligning or stabilizing elements may also be implemented with the recessed cavity retaining wall block. For example, a lip or other aligning element may be integrated into the retaining wall block to further stabilize the system. - It should be noted that reduction in weight of such retaining wall blocks has a number of advantages. Not the least of these advantages is the reduction in shipping costs and the ease of handling during construction. It may be noted that homeowners often purchase such blocks, and because retaining wall blocks of smaller size must be, in many instances, solid in fabrication for purposes of structural integrity, it is important that such solid blocks be of a lighter weight if possible. The present invention provides for such a lighter weight block, although from the top it appears to be a solid block of much heavier weight. The block may be cast out of concrete or fabricated by molding concrete on a block machine. Other fabrication techniques are, of course, are contemplated in accordance with the principles of the present invention.
- Further to the above, it should also be noted that in building a large retaining wall, the retaining wall blocks must be structurally sound. A solid block is going to provide that structural integrity. A block with voids may have thin wall areas that could break or collapse. Therefore, one feature of the present invention is reducing the weight of the retaining wall block without introducing voids within the volume of concrete in the block.
- It is thus believed that the operation and construction of the present invention will be apparent from the foregoing description. While the apparatus shown and described has been characterized as being preferred, it will be readily apparent that various changes and modifications could be made therein without departing from the scope of the invention as defined in the following claims.
