Abstract
Embodiments relate to an enhanced method for building walls by primarily reducing the time for assembly. The design is for a molded multi-segment plastic composite construction block that interlocks horizontally, vertically and orthogonally with a clearance-fit, does not require mortar for structural integrity and is self-aligning. The blocks are molded out of natural-fiber reinforced thermoplastic composites with thermal expansion coefficient less than 0.0002 per degree Celsius and compression strength greater than 60 MPa.
Claims25
A segmented construction block with each segment length equal to segment width allowing for assembly of walls with blocks that can interlock horizontally, vertically and orthogonally with lips and insets that have a clearance-fit and are located around the perimeter of each segment and wherein the material used to mold the block is comprised of a thermoplastic composite with between 20 and 70% natural fiber, up to about 5% coupling agent, up to about 10% pigment, up to about 10% fire retardant, up to about 1% antioxidant, up to about 1% UV stabilizer, up to about 1% heat stabilizer, up to about 5% fungicide, and up to about 70% thermoplastic.
