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.
System of stackable blocks (1) each of which has two joining sides (3, 5) for joining to blocks situated above and/or below it, which joining sides are provided with bearing (15, 17) surfaces, which form the contact surfaces with blocks situated above and below them, in which at least one of the joining sides is at least partially provided with a dressed area, which dressed area forms the bearing surface of this joining side, and in which this bearing surface is situated exactly at a desired distance (18) from the opposite bearing surface of the same block, characterized in that there is at least one groove (19, 21) in each joining side (3, 5) which is opposite a groove in a joining side of a block situated above or below it, and that the system furthermore comprises joining elements (23) which are situated in the grooves opposite each other.
System according to one of the preceding claims, characterized in that the height (H1) of the joining elements (23) is equal to or a little smaller than the sum of the depths (H2) of the grooves (19, 21) in the blocks (1) stacked on top of one another.
System according to one of the preceding claims, characterized in that the system furthermore comprises wall ties (41) and tie plates (47) for joining the wall ties to the blocks, which wall ties are provided with a thread (45) or parallel circumferential grooves, and which tie plates are provided with an opening (49) which extends from a side (51) of the tie strip to a distance from the opposite side (53) of the tie strip, and in which the tie strip (47) with the opening (49) is situated over a wall tie (41) and the wall (55) of the opening is situated partially in the thread (45) or the grooves of the wall tie.
Method for stacking blocks (1) with joining elements between them, each block of which is provided with two joining sides (3, 5), for joining to blocks situated above and/or below it, in which each joining side is provided with at least one groove (19, 21), and in which after laying a course of blocks, joining elements are placed in the grooves, after which a further course of blocks is laid with the grooves over the joining elements, characterized in that the joining elements are strips of a flexible material having a width which is greater than the width of the grooves, in which the joining elements are put under pressure in the grooves of a course of blocks and when laying a further course of blocks the joining elements are also put under pressure in the grooves of the further course of blocks.
Method for stacking blocks (1) with joining elements (23) between them, each block of which is provided with two joining sides (3, 5), for joining to blocks situated above and/or below it, in which each joining side is provided with at least one groove (19, 21), and in which after laying a course of blocks, joining elements (23) are placed free of tension in the grooves (19), after which a further course of blocks (1) is laid with the grooves (21) over the joining elements, characterized in that the joining elements (23) are profiled flexible strips having a width (W1) greater than the width (W2) of the grooves (19, 21), in which when laying a further course of blocks (1) the joining elements (23) are put under pressure in the grooves (19, 21).
