Definitions

  • Panel for the construction of a structure resistant to bending such as a floor or the like
  • the present invention relates to a panel, in particular for making a structure which is resistant to bending, such as a floor of a construction, in particular of a building.
  • expanded polystyrene lightening blocks are used to make floors. Between said blocks there is a concrete casting designed to form a corresponding floor joist extending between the lightening blocks which are positioned side by side and also comprising reinforcing rods embedded in the concrete casting.
  • a resistant element which supports the lightening blocks and which is made of concrete applied on a brick base.
  • Said resistant element supports a complex steel rod lattice, designed to form the reinforcement for the subsequent floor joist portion and is interposed in the transversal space between the lightening blocks.
  • Said resistant elements of the prior art panels are heavy and make panel preparation complex and lengthy.
  • a steel rod lattice has to be prepared, then positioned between the lightened blocks and on the brick base. It is also necessary to add above the base an even minimal amount of concrete in order to form the resistant structural part of said panel supporting element. Finally, before being able to use and transport the panel, it is necessary to wait until the concrete has at least partly hardened.
  • such a resistant element of the reinforced concrete panel provides the panel with a resistance to bending which is limited and is not sufficient to withstand the subsequent concrete casting step, and so an excessive number of crosspiece supports have to be used.
  • a panel in particular for making a structure which is resistant to bending, such as a floor of a construction, or the like, in particular of a building, the panel comprising at least one lightening block, in particular a first and a second lightening block positioned side by side and a resistant element between the lightening blocks which are positioned side by side; said blocks, in particular, being made of insulating material, particularly plastic material, preferably expanded material, such as expanded polystyrene, the panel being characterised in that the resistant element is made of metal material and forms means for supporting the lightening blocks.
  • the panel obtained, in particular for making floors and the like, is easily and rapidly prepared, may have a low weight and a high resistance to bending, and is suitable for allowing particularly easy production of the corresponding construction structure.
  • the invention also relates to an advantageous resistant element and to an advantageous process for making a structure which is resistant to bending, such as a floor or the like.
  • the invention also relates to an advantageous process for making a resistant element and to an advantageous process for making a panel, both, in particular, for obtaining a structure which is resistant to bending, such as a floor of a construction, in particular of a building or the like.
  • Figure 1 is a perspective bottom view of a preferred embodiment of the panel according to the present invention.
  • Figure 2 is a perspective top view of the preferred embodiment of the panel according to the present invention.
  • Figure 3A is a cross-section of the preferred embodiment of a resistant element according to the present invention
  • Figure 3B is a cross-section, showing the components, or portions, of the preferred embodiment of the resistant element according to the present invention
  • Figure 4 is a perspective top view of an intermediate step of the procedure for making the floor which can be obtained using the preferred embodiment of the panel
  • Figure 5 is a perspective top view of a final step of the procedure for making the floor which can be obtained using the preferred embodiment of the panel
  • Figure 6 is a cross-section of a portion of floor obtained using the preferred embodiment of the panel according to the present invention.
  • Figure 7 is a cross-section of a detail of the lightening block illustrating in particular the grip tooth insertion zone.
  • FIG. 1 and 2 illustrate a preferred embodiment of the panel 10 for making a floor 11, in particular illustrated in Figures 5 and 6, of a construction, particularly of a building.
  • the floor is of the type comprising lightening blocks 13 and a concrete casting 15 forming corresponding longitudinal floor joist 17 portions extending between the lightening blocks 13 which are positioned side by side.
  • the panel 10 comprises at least a first and a second lightening block 13, 13, positioned side by side, and a resistant element 12 forming means for supporting the panel blocks 13, 13, and extending between the blocks 13, 13 which are positioned side by side.
  • the lightening blocks 13, 13 are, in particular, blocks of insulating material, paiiicularly blocks of plastic material, preferably made of an expanded material such as expanded polystyrene.

  • the resistant element is a metal element 12 extending longitudinally between and supporting the first and second blocks 13, 13.
  • the panel is prepared easily and rapidly compared with similar panels prepared according to the prior art. It is no longer necessary to provide a corresponding concrete casting to make the resistant element to be interposed between the lightening blocks.
  • the panel 10 also has a weight which is advantageously low and a high resistance to bending, allowing it to avoid, or at least reduce, the use of crosspiece supports for making the corresponding construction structure.
  • the metal element 12 comprises a portion formed by or at least partly consisting of a corresponding metal plate.
  • the resistant element 12 forms transversal retaining means between the first and second blocks 13, 13 of the panels.
