Prefabricated building product structure made of sintered expanded polystyrene and method for the relative production
A prefabricated building product structure made of sintered expanded polystyrene includes a composite assembly formed by aggregating steel to the sintered expanded polymeric mass, preferably of high density, and by embedding therein rod-like steel elements, preferably pre-assembled and forming a cage of electrowelded elements. A method of related production includes positioning the rod-like steel elements, preferably pre-assembled forming a cage of electrowelded elements, in the mold for the expansion of the polystyrene, pouring in the mold incoherent granules or pearls obtained from the polymerization of the styrene, with grain size and volume appropriate for the attainment of a high density finished product, expanding and sintering or amassing the incoherent polystyrene through contact with water vapor at a temperature higher than ninety degrees centigrade, and trapping the armor in the monolithic mass thus obtained to attain a solid geometry, according to the mold, of armored sintered expanded polystyrene.
1. A prefabricated building product structure made of sintered expanded polystyrene comprising:
a composite material assembly having,
a steel reinforcement structure embedded into a high density sintered polystyrene body,
wherein the steel reinforcement structure comprises rod-shaped elements embedded inside the sintered polystyrene body, buried under a surface thereof,
wherein the rod-shaped elements are assembled to form an inner reinforcement cage having twinned nettings joined by crosspieces, and
wherein said twinned nettings are mutually matched and laterally staggered to form the inner reinforcement cage, so that a longitudinal wing projects from sides of the inner reinforcement cage.
2. The prefabricated building product structure according to claim 1 , wherein said rod-shaped elements are pre-assembled to form the inner reinforcement cage through mutual joining by electro-welding.
3. The prefabricated building product structure according to claim 1 , wherein said longitudinal wings are configured as sheets or are configured as closely knit nettings.
4. The prefabricated building product structure according to claim 1 , wherein said longitudinal wings adapted to being brought into proximity with each other and connected to one another.
5. The prefabricated building product structure according to claim 1 , wherein any plurality of elements forming the cage protrude from the surface of the polystyrene body, for joining annexed to other building product structures when laying on site.
6. The prefabricated building product structure according to claim 1 , wherein said building product structure is shaped as a panel having a plurality of sectioned longitudinal parts, within which said wings of said cage are embedded.
7. The prefabricated building product structure according to claim 6 , wherein said longitudinal parts of said panel are provided on two complementarily shaped sides, so that on one side there is provided a longitudinal groove while on another there is a longitudinally complementary relief.
8. The prefabricated building product structure according to claim 6 , wherein said longitudinal parts of said panel are provided on two complementarily shaped sides so that coplanarly neighboring panels are constrained mutually by mating two complementarily shaped sides of the neighboring panels.
