  • the block can have many dimensions. Preferred dimensions for the block are the following (considering the block frontally): width between 15 and 45 cm, height between 5 and 20 cm, depth between 9 and 15 cm.
  • a plurality of blocks 1 is coupled so that a structure 100 is formed.
  • the coupling between a first block 1' and a second block 1", arranged on the first one can occur by means of simple sliding the second block 1" on the first block 1', along a direction perpendicular to the front surface of the first block 1', so that the lower surface of the second block 1" is overlapped on the higher surface of the first block 1'.
  • the hook 20 of the second block is held in the seat 13 of the second block, since supported by the upper surface of the first block (see the position of the hook of the first block, up in the structure of figure 7 ).
  • the hook 20 of the second block arrives at the seat 14 of the first block 1', it is rotated downwards, i.e. falls in the seat 14.
  • Another sliding of the second block causes the hook 20 of the second block 1" to be engaged with the hooking means 21 of the first block 1'.
  • the seat 14 is extended so that the hook 20 always remains in the second coupling position, i.e. at the beginning it is not supported by the first block 1' in the seat 13 of the second block 1".
  • the above described operations are repeated in series with other blocks 1 so that a structure 100 is formed, as for example a partition.
  • the blocks can be overlapped according to many methods. For example, by aligning them the one on the other one, by making the lower and upper surfaces of two overlapped blocks coincide as shown in figures 8 and 9 ; according to a possible alternative they can be offset-overlapped as in figure 10 , so that a greater side extension of the structure 100 is allowed.
  • the blocks 1 it is so possible to obtain a partition, or for example by providing suitable spaces in the structure 100 other pieces of furniture such bookcases, wardrobes etc.
  • the coating layer 3 (or the coatings layers 3, 4) is applied to the respective block 1 by coupling the elements 10, 11 with each other, as above described.
  • Such operation can be carried out in different times, and generally before beginning the construction of the structure 100 or at the end of the same (possibly also during the construction operations of the structure 100).
  • the coating 3 is released from the main layer 2 (also when the block 1 is parte of the structure 100) and to replace it with a different coating, according to needs.
  • each modular block in order to make the fastening between the various blocks more efficient and to avoid little sliding of the ones on the other ones due to vibrations, can comprise, in its main layer, at least a notch (15) provided in the upper surface and at least a notch provided in the lower surface. Said notches are also provided with an outwards opening on one of the side surfaces of the block, which will allow the introduction of an outlet key or other tool, whose functioning is described soon. Yet, more preferably, each block comprises at least two notches realized in the upper part and two in the lower part. The positioning of the notches (15) is such that, when two blocks are assembled as shown in figures 9 and 10 , the lower notches of the upper block coincide with the upper ones of the lower block.
  • each one of the notches provided in the upper surface of each block it is introduced an element (15-a) subjected to an elastic force, configured so that it can move vertically between a first rest position, in which said element projects from the upper surface of the block, and a second compressed position, in which said element does not project from said upper surface.
  • said element subjected to an elastic force is a pin biased by a helical spring.
  • said element (15-a) is compressed to raise the edge of the upper block up to its vertical alignment with the lower block.
  • the notches of the upper block are aligned with the ones of the lower block, thus allowing the elastic element to raise the element which will be positioned inside the notch provided on the lower surface of the upper block.
  • the coating layer (3) still being valid what said concerning the fastening means to the main layer, comprises elements with projecting shapes and/or openings intended to particular applications as a function of the ambient the wall is intended to.
  • said coating layer can comprise shelves, clothes hangers, frames for pictures or paintings, clocks, lightening devices.
