Description of the preferred exemplary embodiment In the following description an example will be shown of an embodiment of an apparatus that carries out the method according to the invention. 10 In particular, in figure 1 an apparatus is described according to the invention suitable for making automatically conglomerate structures of buildings, it comprises a framework having four uprights 3, 4, 5, 6 capable of supporting a horizontal frame 1 movable 15 vertically along such uprights. Horizontal frame 1, with closed shape has at least two parallel sides 2 for slidingly engaging with two ends of a bridge crane 15 which holds an operating head 16. Altogether, operating head 16 moves along arrow 19 20 perpendicular to the sliding direction 18 of bridge crane 15 and frame 1 can move vertically along arrows 11, 12, 13, 14. In figure 2 an end portion of bridge crane 15 is shown more in detail. The bridge crane structure 15 25 comprises a beam 21, having at each end a couple of wheels 23 that engage with the inner part of the beams 2 of figure 1. A guide 20 is provided integral and parallel to beam 21 that slidingly holds a slide 24 of operating head 16, which is capable of spraying a liquid binder on a just 30 deposited layer of granular material. Beam 21 supports a hopper 17 with elongated shape, which extends along the length of beam 21 and is adapted to deposit a predetermined amount of granular material at one end of the depositing plane. Along beam 21 a blade is arranged WO 2006/100556 PCT/IB2006/000596 8 for spreading the granular material just deposited by the above described hopper 17. Figures 3 and 4 show respectively a perspective view and a front view of an apparatus according to the 5 invention and figure 5 is a view of operating head 16, relative to a first operative deposition step of an amount of granular material, in which frame 1 is at the position of zero (ground level), bridge crane 15 is in its first stop position and operating head 16 is in its first stop 10 position. The apparatus comprises four containing walls 31 that define a volume that is going to be filled with granular material following the method according to the invention. 15 Figures 6, 7 and 8 show the apparatus according to the invention, during a step of spreading the granular material along the exposed surface of the previously deposited layer. In this step bridge crane 15 moves towards its second limit stop, distributing and leveling 20 the granular material deposited in the previous step, by blade 22. Figures 9, 10 and 11 show the apparatus at the end of the previous step. Frame 1 is still at ground level, bridge crane 15 has achieved its second limit stop and is 25 still, while operating head 16 is still at its first limit stop. Figures 12, 13 and 14 show the apparatus in a step of back stroke when operating head 16 sprays the binder on the layer of granular material only at the solid areas of 30 the calculated cross section. In this step frame 1 is still at the zero level, bridge crane 15 moves back and operating head 16 sprays the binder and moves along its sliding axis. Figures 15, 16 and 17 show the apparatus at the end WO 2006/100556 PCT/IB2006/000596 -9 of the spraying step, when frame 1 is still at ground level, bridge crane 15 and operating head 16 have moved back to their first limit stop. In this position, the doser 40 of bridge crane 15 is filled with an amount of 5 granular material to be deposited in the next step. Figures 18, 19 and 20 show the repetition of the previous steps, in particular of the first step, on a second distribution level reached by raising frame 1 for a height equal to the pitch. In this step the amount of 10 granular material stored in the previous step is deposited by doser 40. When frame 1 is stepped up, bridge crane 15 and operating head 16 are at the respective first limit stops. In figure 21 the apparatus is carrying out its last 15 step before completion of the conglomerate structure. In figure 22 the structure of building 50 has been completed. The next steps are the evacuation of the granular material not cemented by the binder, thus leaving the cemented part and then the structure, and removing the 20 containing walls and then the apparatus. Figure 23 shows a cross sectional view of a portion of structure comprising two layers of granular material 61 and 62 deposited in two successive steps. The resin is selected from the group comprised of epoxy resin and cross 25 linking polyurethane; it has a viscosity set between 3 and 10 poises, and preferably between 6 and 8 poises, and is adapted to be fluid enough to penetrate between the granules of the granular material for a height corresponding to pitch 68, thus achieving the layer 64 of 30 granular material previously formed. In particular, said granular material has a granulometry set between 0,1 and 2 mm, and preferably between 0,5 and 1,5 mm; this way the granular material has a maximum effective porosity adapted to cause said binder WO 2006/100556 PCT/IB2006/000596 - 10 to penetrate between the deposited granules up to reaching the layer already sprayed in the previous cycle. The foregoing description of specific embodiments will so fully reveal the invention according to the 5 conceptual point of view, so that others, by applying current knowledge, will be able to modify and/or adapt for various applications such embodiments without further research and without departing from the invention, and it is therefore to be understood that such adaptations and 10 modifications will have to be considered as equivalent to the specific embodiments. The means and the materials to realise the different functions described herein could have a different nature without, for this reason, departing from the field of the invention. It is to be 15 understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
