SYSTEM OF STACKABLE BLOCKS AS WELL AS BLOCK AND A JOINING ELEMENT OF THE SYSTEM

A system consists of blocks ( 1 ) provided with grooves ( 19, 21 ) as well as joining elements ( 23 ) which are situated in the grooves for positioning the blocks with respect to each other. The block ( 1 ) has two joining sides ( 3, 5 ) for joining the blocks situated above and/or below it. Starting with a rough, undressed block, a layer of the rough block is removed from both joining sides over the whole surface, so that the joining sides ( 3, 5 ) become bearing surfaces ( 15, 17 ), which form the contact surfaces with the blocks above and below them. When dressing the rough block one makes sure that the distance ( 18 ) between the bearing surfaces ( 15, 17 ) lies within narrow tolerances of a desired value. Because of this, the blocks in a course lie precisely in a horizontal plane. The grooves ( 19, 21 ) and joining elements ( 23 ) make sure that the blocks lie precisely in a vertical plane. The joining element ( 23 ) is a profiled strip made of a flexible material having a width W1 which is greater than the width W2 of the grooves.
