Building block and extreme weather building system

Abstract

The present invention relates to the reuse of otherwise discarded plastic to be used as building material and is resistant to extreme weather conditions. A building block comprises a multiple sided hollow box, wherein the sides of the box are tapered, with at least one keyway respectively slotted on at least two faces of the hollow box and an interlocking key which has a corresponding shape with the keyway to tightly interlock in the keyway.

1 . A building block comprising:
 a multiple sided hollow box, wherein ends of the box are tapered;   at least one keyway respectively slotted on at least two faces of the hollow box; and   an interlocking key which has a corresponding shape with the at least one keyway to be tightly interlocked in the at least one keyway.   
     
     
         2 . The block of  claim 1  wherein at least one of a top face or a bottom face of the block s open. 
     
     
         3 . The block of  claim 1  wherein a left face and a right face of the box are tapered at an angle of about 10° degrees. 
     
     
         4 . The block of  claim 1  wherein the at least one keyway comprises two keyways respectively slotted on each of a front face, a rear face, a left face and a right face of the box. 
     
     
         5 . The block of  claim 1  wherein the box is filled with locally available infill material, but not limited to earth, sand, gravel, mud, and concrete. 
     
     
         6 . The block of  claim 5  wherein the weight of the infill material provides sufficient resistance to wind forces. 
     
     
         7 . The block of  claim 1  further comprising an aperture adapted to be used for reinforcement or a passageway for members in each face where there is the at least one keyway. 
     
     
         8 . A building system for extreme weather, comprising building blocks and interlocking keys as defined in  claim 1 .
