Apparatus For Providing An Interlocking Thermoplastic Building Blocks

Abstract

Embodiments of the present disclosure provide an apparatus for providing

an improved building block. The disclosure provides for a block made from recycled or new thermoplastic materials or other blend of materials. The new block design provides for geometric interlocking capabilities from block to block, layer to layer and wall to wall via an Interlocking Post and screws. This Post will not only mechanically interlock the block system but will as well mechanically hold the block in position via a metal screw.

Claims

1) A new apparatus of a construction block FIG. 1, that is designed to utilize recycled plastic material in part or in whole. The geometry of the structural block may be in the form of a rectangular box as depicted in FIG. 1, of or in other shapes such as square cubes, parallelogram cubes or other shapes as required. The apparatus is designed to repurpose what would normally be waste stream plastic material (and other) for use as a natural insulator for an injection molded structural block. The aforementioned other materials could possibly be chemical additives (to make it more fire retardant), fiber additives, such as glass fibers or carbon fibers to make the block stronger and less resistant to polymer creep. Once the recycled material is repurposed into this closed loop system, blocks can be continuously reground into new material and remolded into blocks. It should be mentioned here, as well, that the described embodiments in no way are intended to limit the use of materials, plastic or other, in fact the reverse is true. New design applications will require the use of different geometry, possibly different base materials, both new and used, such as other plastics, steel, wood, man-made fibers, etc.

2) The apparatus of claim 1, further provides openings 102, to be molded into the structural block that will allow the block to be much lighter in weight, while maintaining adequate structural integrity. These molded openings 102, as well provide for an open column when blocks are stagger-stacked, thus providing a vertical column opening for concrete or other reinforcement to be poured or additional insulation to be added.

3) The apparatus of claim 1, further provides for these vertical openings, 102 to serve as new options as paths for electrical wiring, heating and air conditioning systems to be routed, constructed and assembled. As these openings, 102 are molded into each block, the open paths naturally provided by molding eliminate the need for technicians to cutaway what would be existing structural wall fabrication in either wood form or concrete form to create a path for wiring, HVAC or other. This new method creates an obvious major times savings, and therefore dollar savings for these services to be installed. This new method insulates and protects the service components within the wall by enclosing them within the boundaries of the block and said openings, 102 molded into the block.

4) The apparatus of claim 1, further provides for a spline and cavity self alignment system, 101 molded into the structural blocks. A spline and corresponding bottom cavity, FIG. 2, 103 apparatus not only aligns the blocks in construction process but provides a unique positioning and anchoring mechanism for the screw. Furthermore, this spline, 101 design arrangement provides a critical surface to mechanically anchor the block together with the Interlocking Post, FIG. 5 and typical industry metal screws designed for use in plastic materials. This top spline and bottom cavity, 101 and 103 geometry in the block design serve as functional wind and moisture barrier on both the top and bottom surfaces of the blocks. These surfaces, 101 and 103 are molded directly into the structural blocks for strength, ease of assembly and accurate placement of the blocks.

5) The apparatus of claim 1, further provides for a molded in T shaped cavity 100, interlocking apparatus to mechanically hold structural blocks together as well as interlock one wall to a connecting perpendicular wall at the wall corners. This T shaped cavity, 100 molded into each end (lengthwise) of the block provides for connection of these structural blocks devoid of any special industry skills as is now required for cinder block and mortar construction. Time and labor savings are a direct result of this alignment and attachment system, along with other obvious construction saving techniques that are not available today in cinder block construction. This system is uniquely stronger than conventional cinder block wall construction, is easier to construct and mechanically attaches block together rather than relying heavily on a rather weak chemical attachment and mechanical attachment.

6) The apparatus of claim 6, further provides for an Interlocking Post, FIG. 5 that interlocks and holds block to block and wall to wall via the geometry of the molded in cavities, 100 incorporated into individual blocks at each end and the corresponding shape molded into the Interlocking Post. The Interlocking Post, FIG. 5 also fills the vertical cavity left when two blocks are positioned end to end for construction, thereby eliminating voids and cracks that would normally allow air and moisture to penetrate through the wall at the joining location.

7) The apparatus of claim 6, further provides for a vertical thru hole and counter-bored shape into the Interlocking Post, 502 molded in to access the attachment of a metal screw or other and to attach and anchor the Interlocking Post to the molded in cavity shape of the blocks. This creates a sturdy mechanical attachment at each end of the blocks lengthwise but as well anchors a block layer to the layer below it.

8) The apparatus for claim 6, further provides for the designed continuation of the Interlocking Post spline shape to match the geometry of the splines and cavities, 102 molded into the blocks, This design geometry is intended as well to minimize wind and moisture penetration through the wall. As a final precaution, adhesive caulking can be installed into the block joint assembly, either prior to or after stacking of the blocks. Here again, it should be emphasized that the above described embodiments of the present disclosure, particularly the illustrated embodiments, are merely examples of possible implementations to help determine a better understanding of the principles of the disclosure.

9) The apparatus of claim 6 further provides for wing shaped out-board structures, FIG. 5, 500 molded into the main body of the Interlocking Post, FIG. 5. These wing shapes, for lack of a better term, allow the post to attach and hold two blocks 100, together in the X and Y positions and in alignment.

10) The apparatus of claim 6, further provides surfaces and geometry to hold two blocks together in the Z position by utilizing the bottom surface of the wing structure of the Interlocking Post. A permanent holding of the Interlocking Post, FIG. 5 in the X,Y,Z position is accomplished by the mechanical attaching screw.

11) The apparatus of claim 6, further provides for a thru hole, 502 in the Interlocking Post, FIG. 5, that is vertically positioned in the center of the block. This thru hole, 502 is counter-bored near the top of the Interlocking Post, FIG. 5 and is located centrally within the post to allow the mechanical screw, FIG. 6 to apply equal force from the bottom of the winged structure, 501 and as well centrally position and hold the blocks via the molded in cavities, 100 via a force from the screw, FIG. 6.

12) The apparatus of claim 12, further provides for a designed metal screw, FIG. 6 to mechanically attach (via threads in the screw) and hold in position the Interlocking Post, FIG. 5, and thereby hold and position the blocks via their injection molded cavities, 100.

13) The apparatus of claim 6 further provides for a designed and injection molded barrier structure FIG. 5, in the top of the block designed to restrict any wind, moisture or other contaminants from penetrating the wall structure. This barrier, 503 is designed to be of a common height as adjacent block splines, 101 thereby continuing the interlocking and aligning spline, 101 geometry through the block system.

DETAILED DESCRIPTION

[0026] Having summarized the main aspects of the present disclosure, reference can now be made in detail to the description of the disclosure as illustrated in the drawings. While the disclosure will be described within these drawings, there is no intent to limit it to the embodiment or embodiments herein. On the contrary, the intent is to cover all alternatives, modifications and equivalents included within the spirit and scope of the disclosure as defined by the appended claims.

[0027] Reference is now made to FIG. 1 which is a perspective view of an apparatus for providing an improved building block system. This system is comprised of FIGS. 1, 2, 3, 4, 5 and 6. The assemblies and sub-assemblies of these components can be used in any manner compatable with the geometry of the design. These component blocks share common design intents to allow them to be stackable, interlocking, self aligning and mechanically attachable to each other, not excluding other obvious design intentions. The rectangular shape should also be interpreted as capable of having a square, rectangular, or trapezoidal shape as well as others as may be re necessary.

[0028] The block design incorporates a female interlocking shape and attachment design 100, at each end of the block to allow a unique interlocking and mechanical holding of block to block attachment. The block are held together via a mechanical screw assembly provided in FIG. 5 of the embodiment that fits uniquely within 100 the female design embodiment. This unique design also allows for superior holding and attachment of one wall to opposite directional wall, thereby allowing block to block and layer to layer and wall to wall supporting attachment. In addition to this mechanical screw attachment. The blocks may also be additionally held together and further waterproofed with adhesive compatable with the polymer based materials. The adhesive properly applied to upper and lower perimeter surfaces prior to installation of the block and subsequent attachment of screws will securely hold the assembly in place while allowing the glue to dry. The proper installation of adhesive will make the wall water resistant as the polymer material itself is inherently resistant to water. Additionally, waterproofing repairs can as well be made from the outside of the wall after the wall is stacked and screwed into place. Best Manufacturing Practices should as well be implemented for best results.

[0029] Reference is now made to the vertical cavities 102 designed into the block thus allowing the lightening of the block vs. a conventional concrete block without sacrificing any structural strength. These cavities also provide a path to pour concrete into vertical columns after the walls have been stacked. Here again, the design of the screwed together block system will provide adequate strength in most cases to allow pouring without additional internal or external wallforms being fabricated, thereby saving considerable time and material. These PolyBloks, at approximately half the weight of a concrete block will be greatly appreciated by the industry as half the weight equates to considerable savings in shipping costs.

[0030] One of the most revolutionary capabilities of the design eliminates the need for mixing mortar and skilled labor to create a wall structure. The unique system utilizes a male spline and female corresponding cavity design 101, which allows the accurate alignment of the blocks. This spline/cavity design as well provides for additional centerline mass as well as a structurally capable area to attach screws for holding the blocks. The spline/design also plays into the overall design by creating a barrier for blocking wind and moisture. The design should as well minimize any extreme failure modes such as splintering/cracking and total failure of the wall. The wall structure is designed to perform better in earthquake situations relative to it's superior failure mode characteristics and mechanical attachment capabilities. While the design is not limited to the aforementioned polymer material, the ability to injection mold the recycled or virgin material vs. other materials is a critical advantage in the performance as well as the economics of the PolyBlok design.

[0031] In further reference to the design, FIG. 2 depicts all of the aforementioned design characteristics mentioned in reference of FIG. 1. In addition, this right angle geometry of the corner block FIG. 2, provides an accurate 90 degree right angle corner for the wall. This feature also eliminates any measuring or special layout for accurate wall
