Concrete Block

Abstract

A concrete block for construction, the block having a front wall and a rear wall. The front and rear walls are spaced apart by a pair of transverse webs. Each of the front and rear walls comprises a middle portion and a pair of end portions, wherein the end portions have a uniform thickness that is greater than the thickness of the middle portion.

1 . A concrete block for construction, said block having a front wall and a rear wall, said front and rear walls being spaced apart by a pair of transverse webs, each of said front and rear walls comprising a middle portion and a pair of end portions, wherein said end portions have a uniform thickness that is greater than the thickness of said middle portion. 
   
   
       2 . The concrete block as claimed in  claim 1 , wherein said middle portions have a thickness about the same as said webs, thereby defining, with said webs, a vertically extending box channel. 
   
   
       3 . The concrete block as claimed in  claim 2 , wherein each said end terminates in a flat surface perpendicular to said front and rear walls. 
   
   
       4 . The concrete block as claimed in  claim 3 , wherein said flat surfaces on each respective end of said front and rear walls is coplanar. 
   
   
       5 . The concrete block as claimed in  claim 4 , wherein each said flat surface on each end of a said front and rear wall is provided with a vertically extending, integrally formed bead or groove, each said groove being dimensioned to fit with a said bead. 
   
   
       6 . The concrete block as claimed in  claim 5 , wherein there is a bead and a groove at each end of a said block, and a bead and a groove at each end of a said wall. 
   
   
       7 . The concrete block as claimed in  claim 5 , wherein said block is provided with an end wall at one end thereof. 
   
   
       8 . The concrete block as claimed in  claim 7 , wherein said front and rear walls are provided on their outer facing surfaces, with grooves alignable with said beads. 
   
   
       9 . The concrete block as claimed in  claim 8 , wherein said end wall is provided on its outer surface with grooves alignable with said beads.
