BUILDING BLOCKS
The present invention is a block having an elongated and hexagonal shape. A central void runs through the block. The block is formed of an elastomeric and water-repellant material. The hexagonal shape facilitates stacking of blocks having identical hexagon dimensions, although the elongated dimension, or length, of the blocks may be different. The central void of the block may be filled with one or more materials that impart additional characteristics to the block and the resulting structure.
This invention relates to components for construction generally, and is more specifically directed to building blocks for constructing and/or supporting walls, barriers, dams and the like.
BACKGROUND OF THE INVENTIONBarriers, such as walls, dams, fences and other similar structures are commonly formed of a plurality of blocks. The blocks may be formed of masonry materials, ceramics, metals and other materials.
There is a need for building blocks that are formed of shapes that are easily stacked, and easily connected. There is a need for blocks having elastic properties that are sufficiently rigid to bear substantial loading. Preferably, the blocks are made of commonly available and recyclable materials.
SUMMARY OF THE INVENTIONThe present invention is a block having an elongated and hexagonal shape. A central void runs through the block. The block is formed of an elastomeric and water-repellant material.
The hexagonal shape facilitates stacking of blocks having identical hexagon dimensions, although the elongated dimension, or length, of the blocks may be different. The central void of the block may be filled with one or more materials that impart additional characteristics to the block and the resulting structure. The central void of the block may be filled with a material that resists deformation under load, or which resists impact or which absorbs energy, for example.
A plurality of the blocks may be used to form a barrier, such as a wall, bridge, fence or dam. The blocks may be used to support or stabilize structures. The blocks may reflect solid materials and/or liquid materials and/or absorb energy, including impact and acoustic energy, or act as a conduit for water or other liquids.
The present invention is a building block component that is useful in building a structure. The building blocks may be used to support or stabilize structures. The blocks may reflect solid materials, and repel liquid materials and/or sound waves. The blocks comprise a hexagonal shape about an outer perimeter, and have a central void, which may be round. The central void may be filled with a second material, which may be concrete, metal, earth, rock aggregate, synthetic material or a combination thereof.
The blocks are preferred to be made of an elastomeric and water repellant material. The blocks may be made from natural or synthetic rubber. The rubber may be crumb and/or buffing material, which may be derived from automotive tires, and preferably, used tires. Other products, such as fly ash and/or cement may be added to the crumb and buffing mixture to increase density of the material.
The block has a central void 4. In a preferred embodiment, the central void has a round cross-section that is perpendicular to the central axis of the round void. The central void may be cylindrical, and extend from a first end to an opposite or second end of the block. The central void may open at one or both ends of the block, and closed at or near one or both ends of the block. The round cross section provides excellent structural loading characteristics to the block, while being easy to manufacture and easy to fill with a material. The central void may be of others shape as desired by the user. The central void is preferred to have a diameter of not less than 5 centimeters. The wall thickness of the block with a central void is preferred to be not less than 1.5 centimeters.
The use of an equilateral hexagonal perimeter, along with a round central void, yields a structure that can be oriented with any of the six sides positioned up or down, and in any of the six positions, while providing substantially identical structural integrity in any orientation.
The central void may be filled with materials such as sand, earth or soil; foam, such as flowable polyurethane foam; aggregates, such as gravel or rock; and materials such as concrete or grout that are flowable and harden.
The blocks may be used in combination to form a structure that resists impact by the absorption of energy from the impact. The central void of the blocks may be filled with energy absorbing materials that are compressible upon impact. Such materials include foam, such as closed cell and open cell foam, and flowable foam, including polyurethane foam. Sorbothane®, Bubble Wrap, and other energy absorbing materials may be used alone, or in combination. Some or all of the blocks may be filled with one or more of these materials.
The blocks may be used in combination to form a structure that absorbs sound energy from impact, or to form an acoustic barrier. The central void of the blocks may be filled with materials that absorb sound energy. Such materials include foam as described above; fibers, such as matted or spun fibers; materials having an impervious surface mounted over an airspace; and resonators connected to an enclosed volume of trapped air. Some or all of the blocks may be filled with one or more of these materials.
The blocks may be joined end-to-end by the use of a connector. The connector is preferred to have substantially the same shape as the central void. As demonstrated in
One or more reinforcing materials may be added to the rubber structure to provide additional support and structural integrity to the walls of the blocks. Reinforcement may be accomplished, for example, by placing fibrous material, which may be a synthetic material, into the rubber structure, or by placing composite rings 8, 12 or spirals 10 into the rubber structure, or by placing steel reinforcement bars into the rubber structure.
In one embodiment, a connector 14 may be present on an end of the building blocks. The connector is designed to engage either another building block having a void shaped so as to receive the connector (
A structure may be formed by positioning the blocks with sides of a block adjoining one or more sides of other blocks having the same hexagonal dimensions.
The length of the blocks may be identical in one application. However, in other applications, the length of the blocks may not be identical, as shown in
The blocks may be used to form barriers such as vertically extending bollards 46.
As shown in
The maximum length of a block is limited only by manufacturing and transportation criteria. Dimensionally, the size of a block will be determined by the design of each specific project detail, for example, a paver type block may have a parallel sides dimension of 8 inches with a central void diameter of 6 inches, whereas a unit to be used in a waterway may have an exterior dimension of 24 inches with a central void diameter of 18 inches. The block may be manufactured by compression molding, injection molding, or extrusion or pultrusion techniques.
The block according to the invention is substantially lighter in weight than concrete or masonry blocks of corresponding size. The block can be easily carried by a person and positioned as required to form a structure with the blocks. The central void can be filled with concrete or other materials as described herein after assembly of the blocks in many cases.
