Definitions

  • the present invention concerns modular prefabricated. elements for defining the floor surface of an industrial or civil building, wherein the room will be covered by a floor or by a roof that will be built using said structure elements, as one-use mold or form, whereby by means of said elements a thermo-acoustic insulation is obtained.
  • the present invention provides the realization of prefabricated structural modular elements which, at the same time, accomplish the following tasks:
  • the present invention suggests the realization of prefabricated plate-shaped structural elements, carrying reinforcements for the plate, buried in said elements, as well as reinforcements only partially buried and shaped and proportioned for acting as or for cooperating with the reinforcement of the carrying beams of the floor.
  • Said plate-shaped elements of modular kind will be mounted, side by side, until the whole room is covered, resting on the peripheral beams or on the walls of the carrying structure of the building.
  • Said elements will also form the one-use mold for the construction of the carrying structure made of reinforced concrete of the floor and may be supported in one or more intermediate points by simple props, if necessary.
  • the plate-shaped walls according to the present invention incorporate, in the lower part thereof, a granulated layer that remains partially buried in the particular mixture used to construct the plate of each prefabricated element and which in the lower surface thereof defines the ceiling of the room, said surface having thus such surface features as to allow a perfect adherence of the plaster.
  • the floor will be realized mounting on the prefabricated elements filling blocks of light material, e.g. polystyrene or the like, which together with said plate-shaped elements form the one-use mold and define the side surfaces of the carrying beams which will be obtained, together with the upper slab, according to the conventional system in reinforced concrete conglomerate.
  • Said mold or casting form will allow, with the aid of simple props, if necessary to support the workers and the materials during the casting of the floor in which the same will remain incorporated.
  • each modular structural element is generically indicated with 1 and comprises a plate generally marked 2, having predetermined modular lenght and width.
  • the lenght of each element corresponds to the width of the room to be covered, increased by a value sufficient in order that element 1 may rest on the transversal peripheral beams or on the masonry walls or of any other type delimiting the room, onto which a thermic and acousting insulating floor must be constructed.
  • the structural elements are prefabricated by means of suitable molds.
  • the plate 2 comprises a lower layer 2a and an upper layer 2b; said plate-shaped element 2a, 2b incorporates longitudinal and/or transversal reinforcement irons 3 for the plate 2; said reinforcement means may be obtained by means of an electric welded metal netting, or said reinforcement may have a latticed structure made of longitudinal metal rods 5a, 5b fixed to stirrup rods 4; said reinforcement is buried in the body of plate 2 only for the lower part thereof comprising rods 5a of the reinforcement means 5a, 5b, 4, being welded to reinforcement irons 3, and upwardly projecting from the body of the plate, exactly in those areas in which a carrying reinforced concrete beam must be realized in the floor to be constructed, generically marked 7 in Figure 6 and made of a cement conglomerate.
  • the lower layer 2a of plate 2 is obtained using a granulated mixture of a light inert.
  • a granulated mixture of a light inert For example, a mixture of water, expanded clay mixed up with cement, in the portions of 250 kg of cement per mc of the obtained product, or also simply expanded clay. The mixture will harden and then the same will be crushed so as to obtain granules in the dimensions of 1 mm to 3 mm.
  • expanded clay tile granules, cement mixture and non cement mixture granules and the like may be used.
  • a layer of said granulated mixture is placed, e.g., for a thickness of about 8 mm.
  • metal reinforcement 3 is placed, preferably consisting on a granting onto which a metal latticed assembly 5a, 5b and 4 is welded, fixing the same to reinforcement 3, for each carrying beam belonging to the structural element 1.
  • a polyurethan foam is poured in the mold, said foam penetrating in the pits created between the granules forming layer 2a and that then fills up all the upper layer 2b for the thickness provided for the plate, which thickness may be, e.g., of about 25 mm.
  • the lower part of the or of each latticed reinforcement comprising longitudinal rods 5a and the lower part of stirrup rods 4 adjacent thereto, as well as reinforcement 3 of plate 2 are buried.
  • plate-shaped structural elements 1 which are the object of the present invention, are fabricated in predetermined modular dimensions according to the most common widths of the rooms to be covered. Said elements may be realized in many variants, and precisely: according to the variant of Figure 2 as element la of a width substantially equal to that of a beam; according to the variant of Figure 3, where an element is shown in the form of a flanged joist lb, the width thereof varying between 0,20 m and 0,80 m; according to the variant of Figure 4 wherein the width of element ln is equal to a multiple of the one of flanged joist lb of Figure 3.
  • the constructive element lc is preferably realized in a width twice the one of a flanged joist lb, i.e. equal to the distance between two centres of the floor; said plate-shaped element will therefore comprise two latticed reinforcements 5a, 5b, 4 for the realization of two supporting beams 7 of the floor.
  • the floor will be built as follows. A number of prefabricated elements la, lb, lc..., are set up in contact side by side, as are needed for covering the room, whereby the ends thereof are resting on the transversal walls or on the transversal peripheral beams. If the room is very large, the prefabricated elements may be supported by simple intermediate props or stands. Each plate 2 may be provided, in correspondence to the longitudinal edges of elements 1 (la, lb, lc...) with an outline 11 for a better coupling between prefabricated elements 1 in contact.
  • the ceiling surface therefore will be defined by the combination of all lower surfaces of elements 1 whereby said surface, due to the granulated material incorporated in lower layer 2a of plates 2, is perfectly suitable for the application of the plaster or other coating means.
  • the irons of the latticed reinforcements 4, 5a, 5b will .partially project from the upper part of element 1 in that area where the respective reinforced supporting beams 7 will be obtained.
  • Blocks 6 in combination with the body of plates 2 form the one-use casting mold which will remain incorporated in the floor and in which blocks 6 together with plates 2 define the mold for the casting of each beam to be built, while blocks 6 delimit, with the upper face thereof, slab 8.
  • other reinforcement irons may be mounted for the beams and irons 12 for the reinforcement of slab 8; now the cement mixture will be casted-with the conventional technique.
  • the obtained floor has the form shown in Figure 6, wherein the prefabricated elements 1, being the object-of the present invention, are strongly incorporated in the floor due to metal latticed reinforcements 5a, 5b and 4,
  • the floor thus is very light and thermically and acoustically insulating, of low cost as there are only small costs relating to the use, mounting and removing of the casting mold. Furthermore, said floor is ready for the application of the ceiling plaster or of any other suitable coating.
  • prefabricated elements according to the present invention may be used not only for obtaining plane horizontal floors, but also sloping floors as well as for realizing pents of a pent roof in buildings for civil houses, in agricultural, commercial or industrial buildings.
