STRUCTURES
Field of the invention The present invention relates to building and, in particular to the automatic construction of buildings or other heavy constructions by a method and a device suitable for reducing the building time and for assisting its relative operations. The present invention is used also to build particularly articulated and complex structures.
Background of the invention
Many methods are known for making buildings, with different construction techniques and materials.
A well known technique uses concrete that is cast in a semi-fluid form in a formwork. With this technique volumes of concrete are obtained having the shape of the formwork used.
This technique has the drawback a complex work is required to obtain complex forms having convexities and concavities, mainly owing to the difficulty to provide formworks with shape complex and owing to the low resistance to pulling stresses of the concrete, which requires the use of steel reinforcements that must be folded to follow the shape of the formwork. Another drawback is the cost of the manual work to make the formwork before casting the concrete and for removing the formworks after hardening.
A further drawback is the cost of the formwork material . Another drawback of the method for construction with concrete is the waiting time necessary for hardening.
It is felt, then, the need of a method for making buildings, which is quick and not expensive, suitable for being carried out with an automatic method .

A further object is to provide a method suitable for providing structures resistant not only to compression, but even to pulling stresses.
Another feature of the invention is to provide an apparatus suitable for carrying out said method.
These and other objects are achieved by a method for building automatically conglomerate structures, characterized in that it comprises the steps of:
- CAD modelling , a structure of building, in particular with a CAD function of surface modelling or of volume modelling, obtaining a computer file structure model;
- sectioning said computer file structure model with horizontal parallel planes according to a predetermined pitch, in order to generate a plurality of cross section planes of the structure comprising solid and empty areas, corresponding to the solid and empty parts of the structure, said planes being sorted from below towards the above; - prearranging an apparatus suitable for depositing in alternation a layer of granular material and a liquid binder within containing walls that define a closed perimeter;
- moving said apparatus within said perimeter in order to deposit a first uniform horizontal layer of granular inert material of thickness corresponding to said predetermined pitch;
- spraying a first layer of binder by said apparatus in order to reproduce a first plane of said cross section planes, forming a layer of inert material and of binder only at said solid areas, said apparatus having a operating head suitable for moving in a horizontal plane; - raising vertically said apparatus according to said pitch;

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. 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 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 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 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 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 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 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 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. 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 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 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 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 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 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 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 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 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 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 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 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 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 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.
