CLAIMS

1) Method for producing panels, prefabricated products and frames for the furnishing industry, characterised in that it comprises forming shaped products made of sintered expanded polystyrene (EPS, expanded polystyrene) with high density comprised between 30 (thirty) and 60 (sixty) kg/m3 in an expanded mould and vapour sintering granules or incoherent beads obtained from the polymerisation of styrene and ensuing obtainment of a monolithic mass with solid geometry obtained from the mould and embedding in the mould at least one reinforcement element constituted by a steel grid before the moulding of the sintered expanded polystyrene for attaining composite products with reinforcement armour means.

2) Method according to the preceding claim, characterised in that it comprises a shape of the moulds with recesses and projections for attaining products with bas reliefs shaped with seats and reliefs suitable to be joined with metalware and accessories for mounting and/or using the finished product.

3) Method according to any one of the preceding claims, characterised in that it comprises positioning - in the moulds - plates, strips, sections and means for supporting the metalware before the moulding of the sintered expanded polystyrene for attaining products with coupling elements for metalware and accessories for mounting and/or using the finished product incorporated initially since from moulding.

4) Method according the preceding claims, characterised in that said reinforcement armouring means and said means for supporting the metalware are arranged mutually welded and joined in the mould so that they remain embedded mutually bound and constrained in the polymeric mass of sintered expanded polystyrene forming the finished product.

5) Method according to any one of the preceding claims, characterised in that it comprises positioning - in the moulds - decorative panels or tables or decorative elements before the moulding of the sintered expanded polystyrene for attaining products with decorative elements incorporated initially.

6) Method according to any one of the preceding claims, characterised in that it comprises localised co-injection of polystyrene with differentiated parameters of volume mass in the same mould for attaining products made of sintered expanded polystyrene with locally differentiated density for reinforcement of the portions subjected to more stress in use in the finished product.

7) Method according to any one of the preceding claims, characterised in that it comprises embedding - in the mould - at least one element in a low density sintered expanded polystyrene before the moulding of the high density sintered expanded polystyrene for attaining lightened products with a stratifically differentiated overall density.

8) Method according to any one of the preceding claims, characterised in that it comprises forming sintered expanded polymeric mass namely prefabricated products and frames for the furnishing industry with high density comprised between 30 (thirty) and 60 (sixty) kg/m3, in an expanded polystyrene mould of any size and shape, by pouring - into the mould - the granules or incoherent beads obtained from the polymerisation of styrene, with grain size and volume suitable for attaining a finished product with high density comprised between 30 (thirty) and 60 (sixty) kg/m3; expansion and sintering namely incorporating the incoherent polystyrene through contact with water vapour injected into the mould at a temperature greater than ninety degrees centigrade and ensuing obtainment of a monolithic mass with solid geometry obtained from the mould.

9) Method according to any one of the preceding claims, characterised in that it comprises any plurality of moulds grouped in the overall of the moulding machinery, with numeric control, in the moulds the beads sinter directly attaining the desired shape and overall shape of the product as well as the relative density, obtained by the mould and the parameters for the supply of the incoherent beads, typical of the latter, injection of the water vapour and ensuing suitable sintering.

10) Method according to any one of the preceding claims, characterised in that said mould is formed so that a product is shaped which is curved in at least one direction and/or which comprises at least one insert so to attain a product shaped, decoratively at the surface, as regards the configuration, at the perimeter and in terms of curvature, as well as in terms of formation of neighbouring portions, to create more complex and articulated products with respect to a simple sheet or panel, integrating a semi- finished product and advanced prefabricated element which - in a single piece - attains a portion developed from a processing point of view as much as possible with respect to the final overall product - in terms of implementation advancement - of the furniture the piece is intended to compose.

11) Method according to any one of the preceding claims, characterised in that said armour has appendages intended to remain outside the moulded product.

12) Method according to any one of the preceding claims, characterised in that it comprises a shape of the mould with recesses and projections, for attaining finished products with shaped bas reliefs, for example channels, guides, reliefs, notches, bas reliefs in general, suitable to be joined with accessories and metalware during the assembly of the finished products in the process aimed at attaining the finished product.

13) Method according to any one of the preceding claims, characterised in that it is alternatively implemented with the systems for producing sintered expanded polyethylene obtained from blocks extracted from a block element or for extrusion- drawing after polymerisation.

14) Method according to any one of the preceding claims, characterised in that it comprises a shape of the mould with interfaces for defining the surface portions of the finished product processed so that there are bas relief decorations, such as for example decorative lines or drawings of any kind and type in the finished product.

15) Panel products, prefabricated products and frames obtainable with the method according to any one of the preceding claims, characterised in that they comprise structure made of sintered expanded polystyrene with a density comprised between 30 (thirty) and 60 (sixty) kg/m3 incorporating a metal armour made of a grid or cages of meshes.

16) Products according to the preceding claim, characterised in that said metal armour incorporated embedded in the products is electrowelded and has size and shape such to interact with fixing means, such as screws and the like, which penetrate into the expanded body and are constrained into the internal meshes, contingently conceived with grid dimensioned suitably for the purpose, as well as shaped for maximising the function of anchoring as well as armouring the assembly means.

17) Panel products, prefabricated products and frames for the furnishing industry according to claim 15, characterised in that they comprise a structure made of sintered expanded polystyrene with a density comprised between 30 (thirty) and 60 (sixty) kg/m3 shaped with grids complementary to the shape of any metalware and accessory suitable for assembly and use, for assembling the metalware to the product subsequently to the constitution thereof, in seats and reception recesses specifically conceived during moulding and deriving from the configuration of the mould.

18) Panel products, prefabricated products and frames for the furnishing industry according to claim 15, characterised in that they comprise structure made of sintered expanded polystyrene with a density comprised between 30 (thirty) and 60 (sixty) kg/m3 incorporating any metalware and accessory suitable for the assembly and use associated to the polymeric mass in moulding constancy, for selectively arranging the accessory in the mould before moulding the product, so that the product remains incorporating - from the origin - the accessory in any position suitably designed, both on the relative surface and, fully or partly, embedded therein.

19) Panel products, prefabricated products and frames for the furnishing industry according to claim 15, characterised in that they comprise a structure made of sintered expanded polystyrene with a density comprised between 30 (thirty) and 60 (sixty) kg/m3, incorporating a metal armour, made of a grid or cages made of electrowelded mesh, to which there is constrained, welded, any metalware and accessory suitable for the assembly and use associated to the polymeric mass in moulding constancy, for selectively arranging the accessory in the mould before moulding the product, so that the product remains incorporating - from the origin - the accessory in any position designed contingently, both on the relative surface and, fully or partly, embedded therein and stably constrained to armour means.
