Interlocking building blocks and mortarless interlocking building system

Abstract

A building system comprising at least one block of claim 1 and further including at least one mortarless side panel including a finished outside surface and at least one dovetail protrusion on an opposing surface for joining the side panel to the at least one blocks, and a connector on each end of the panel for joining the side panel to other side panels, and at least one top cap including a finished top surface.

I claim: 
     
         1 . A mortarless interlocking building block for constructing walls and/or partitions of a building comprising:
 a solid moulded plastic body having a front face, a rear face, opposed top and bottom faces and opposed end faces,   the opposed front and rear faces being substantially identical and including at least two vertically extending dovetail protrusions defining a dovetail recess for matingly receiving a dovetail protrusion of another building component,   one of the opposed end faces having at least one vertically extending recess and the other of the end faces having at least one vertically extending protrusion for mating with a recess of another building block to interconnect adjacent blocks in end-to-end relation, and   the face having at least two tubular protrusions and the bottom face having at least two tubular recesses to lock stacked building blocks.   
     
     
         2 . The block of  claim 1 , further including at least one channel for receiving wiring, piping or reinforcement. 
     
     
         3 . The block of  claim 2 , wherein the corners of the dovetails are rounded. 
     
     
         4 . The block of  claim 3 , wherein the edges of the vertically extending protrusions are rounded. 
     
     
         5 . The block of  claim 4 , wherein the edges of the tubular recesses are chamfered. 
     
     
         6 . The block of  claim 5 , wherein the solid material in the block comprises a mixture of a plastic and an aggregate. 
     
     
         7 . The block of  claim 6 , wherein the plastic is a recycled plastic and the aggregate is a recycled aggregate. 
     
     
         8 . A building system comprising at least one block of  claim 1  and further comprising:
 at least one mortarless side panel including a finished outside surface and at least one dovetail protrusion on an opposing surface for joining the side panel to the at least one blocks, and a connector on each end of the panel for joining the side panel to other side panels, and 
 at least one top cap including a finished top surface. 
 
     
     
         9 . A method of manufacturing mortarless building blocks, comprising the steps of:
 comminuting recycled materials,   mixing comminuted materials,   heating the comminuted mixture,   compressing the comminuted mixture,   moulding the comminuted mixture, and   cooling the comminuted mixture.   
     
     
         10 . The method of  claim 9 , wherein the compressing step is carried out using an auger.
