[0021] FIG. 4 illustrates a perspective view of an alternative embodiment of the reinforcement of an antiperforation building panel according to the present invention;

STATIC DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] With reference to such figures and in particular FIG. 1, an embodiment of a composite building panel made of sintered expanded polystyrene 2 according to the present invention, preferably of the high-density type, preferably from 30 (thirty) to 50 (fifty) kg/m.sup.3, is indicated in its entirety with 1.

[0023] In the mass of the composite building panel 1 made of sintered expanded polystyrene 2 there is embedded at least one steel box-shaped structure, indicated in its entirety with 3, for example formed by two counter-faced sheets 4 and 5, respectively configured with empty fields 6 and filled fields 7, square-shaped in the illustrated embodiment, equally dimensioned and alternatingly arranged in a chequered fashion.

[0024] In the illustrated embodiment, the empty fields 6 are divided into two holes 8, while the full fields 7 have two symmetric parallel fissures 9.

[0025] The empty fields 6 and the full fields 7 are inversely symmetrical in the two counter-faced sheets 4 and 5, so that for each full field on one face there corresponds an empty one on the other and vice versa.

[0026] The two counter-faced sheets 4 and 5 are joined to form at least one box-shaped structure 3 with a plurality of segments or crosspieces 10.

[0027] FIG. 3 illustrates an alternative of the box-shaped structure 3 according to the present invention, where the parallel counter-faced sheets 4 and 5 are bent by 90 to form a corner.

Dynamic Description of the Preferred Embodiment

[0028] Thus, having completed the static description of a preferred embodiment of the prefabricated building product structure made of sintered expanded polystyrene according to the present invention, following is the dynamic description of the same, i.e. the relative operation:

[0029] the products or panels 1 have characteristics similar to analogous reinforced concrete structures, in that sintered expanded polystyrene 2, in the density comprised between 30 (thirty) and 50 (fifty) kg/m.sup.3, is suitable to bear compression stresses comparable to those of concrete, while in terms of stress such synthesis material reveals greater resistance to cracking, hence has greater elasticity, with respect to concrete.

[0030] In the products according to the present invention, same case applying to reinforced concrete, the stress forces are countered by the complementary coadjutant synergic action of the steel box-shaped structure 3, thus obtaining products comparablein terms of structural and mechanical characteristicsto similar reinforced concrete products, but considerably lighter.

[0031] These products, obtained in any shape and dimension depending on the contingent implementation and design needs, may be mutually connected through any means suitable for the purpose to obtain substantially any building structure.

[0032] In this context, the distinctive structuring of the reinforcement 3 of the panels 1 according to the invention, formed by two counter-faced sheets 4 and 5, tied by crosspieces 10, respectively configured with full fields 6 and empty fields 7, equally dimensioned and arranged alternatingly in a chequered fashion in the two sheets, combines the characteristics of lightness typical of structures with antiperforation and anti-breaking characteristics, in that whereas a sheet is open for lightening purposes, the other is closed and vice versa so that a perforating body is blocked in any point of the relative extension.

Alternative Embodiments

[0033] It is obvious that in alternative embodiments, still falling within the concept solution of the implementation example illustrated above and claimed below, the antiperforation building panel structure according to the present invention, may also be implemented and obtained differently, through equivalent technical and mechanical solutions still falling within the scope of protection illustrated and claimed below; In particular:

[0034] the dimensions and shapes of the empty and full fields interposed in the two parallel sheets may be variously obtained to suit the purpose;

[0035] in the illustrated embodiments, the empty fields have a pair of holes and the full ones have fissures, which respectively limit the concept of empty and full thereof; in addition, the emptiness may be solid, without divisions of any kind, just like the fullness can be solid, without any fissures;

[0036] the box-shaped structure may be monolithic or made up of a plurality of coplanar structures, mutually fixed and co-embedded in the expanded polymeric mass.

Advantages of the Invention

[0037] As observable from the previously outlined description of a preferred but non-exclusive embodiment, the antiperforation building panel structure according to the present invention, offers the advantages corresponding to the preset as well as other objects:

[0038] as a matter of fact, it integrates a simple, functional, modular and versatile solution concept to obtain a product suitable to constitute an alternative embodiment with respect to the elements made of reinforced concrete, and a building panel with unprecedented characteristics of robustness combined with lightness, with considerable advantages in terms of reducing weight and simultaneously comparable with other structural and mechanical characteristics as well as resistance to perforation and breaking.
