Definitions

  • the present invention relates to a prefabricated concrete panel with thermally insulating or lightening layer.
  • Prefabricated concrete panels inside which there is a layer of thermally insulating or lightening material are known.
  • Such panels are generally constituted by two layers of concrete which constitute the two larger faces of the panel, and concrete cross-members are arranged between them and mutually connect the two larger faces; said cross-­members are alternated with cavities in which layers of low-­density material are generally placed to act as thermal insulators or lightening elements.
  • the load-bearing function of the panel if required, is performed by reinforcement rods embedded in the concrete cross-members which connect the panel larger faces.
  • the concrete cross-members which join the two opposite faces of the panel provide thermal bridges between the two faces, considerably reducing the effectiveness of the thermally insulating layer. Due to their structure with alternated solid portions and empty portions, these known kinds of panel can furthermore be affected by possibly considerable stresses due to the different thermal expansion of the parts which compose them.
  • a layer of thermally insulating material is applied to the outer walls and is covered by means of single-layer concrete panels which are fixed to the walls thus covered.
  • finishing of the covering is required to conceal the applied layer of thermally insulating material which is laterally visible after application of the panels. Said finishing operations, with rather high costs, are necessary, as well as for aesthetic reasons, also to prevent the insulating layer from being attacked by rodents or birds and by the effects of weather.
  • the aim of the present invention is to solve the above described problems by providing a prefabricated concrete panel which has high performance in terms of thermal and acoustic insulation and of resistance to fire and to the effects of weather, without requiring finishing operations after installation.
  • an object of the invention is to provide a panel which is practically free from thermal bridges between the two opposite faces.
  • Another object of the invention is to provide a panel which has no significant stresses due to thermal expansions.
  • Still another object is to provide a panel which can be manufactured in a simple manner with conventional panel prefabrication systems with modest production costs.
  • the panel according to the invention comprises a reinforcement frame 2 which is substantially constituted by two longitudinal profiled elements 3a and 3b and by two transverse profiled elements 4a and 4b which substantially perimetrically delimit the panel.
  • the reinforcement frame 2 can be made of various materials, such as steel, thermosetting plastic materials, materials additivated with resins and/or polymers, etc.
  • Said reinforcement frame can be made monolithically in a single pre-cast part or can be constituted, as illustrated, by a plurality of parts which are coupled by means of bolts, by fixing means, by gluing, by tying, by welding etc.
  • the profiled elements 3a, 3b, 4a and 4b are provided, on the mutually facing sides of the reinforcement frame, with two wings 5 and 6 which are embedded in two concrete layers 7 and 8 which constitute the larger faces of the panel.
  • the two layers 7 and 8 are mutually spaced so as to define an interspace which is filled with a layer 9 of granular or compact, thermally insulating and/or lightening material which has surface dimensions substantially equal to those of the panel.
  • the layer 9 can be constituted, for example, by polystyrene of any density, cork, foamed clay, polyurethane, rock wool, materials made of mineral and/or polymer fibers, etc.
  • the two concrete layers 7 and 8 can be produced by simply using concrete or concrete additivated with resins, mineral or polymer fibers according to the requirements.
  • additional stiffening transverse profiled elements 10 are provided which are arranged substantially parallel to the transverse profiled elements 4a and 4b and are fixed in the two concrete layers 7 and 8.
  • the profiled elements 10 are fixed to the longitudinal profiled elements 3a and 3b similarly to the profiled elements 4a and 4b.
  • Reinforcement grids 11 and 12 are embedded in the two concrete layers 7 and 8 and can be fixed to the wings 5 and 6 and possibly to longitudinal rods 13 supported by the additional transverse profiled elements 10.
  • Grip elements 14 are appropriately provided along the longitudinal profiled elements 3a and 3b, protrude transversely and longitudinally from the panel and are useful to move it. Said grip elements are also rigidly associated with the transverse profiled elements 4a and 4b or with the transverse profiled elements 10 as well as to the longitudinal profiled elements 3a and 3b.
  • the panel can be obtained by means of a forming box 15 simply constituted by a base plate 16 and by two appropriately shaped lateral shoulders 17 and 18, as illustrated in figure 2.
  • the panels thus obtained constitute load-bearing or self-supporting construction elements, depending on the reinforcement frame 2 used, which are placed mutually adjacent by means of coupling profiled elements 19 fixed to the profiled elements 3a, 3b, 4a, 4b which constitute the reinforcement frame.
  • the longitudinal or transverse profiled elements which constitute the reinforcement frame can affect substantially all the thickness of the panel, acting as concrete containment element and making unnecessary the use of the forming-box shoulders to form them.
  • the profiled elements arranged on two opposite sides of the panel externally have mutually associable configurations, in particular counter-­shaped configurations, for example of the male-female type, thus also avoiding the use of coupling profiled elements 19.
  • the reinforcement frame indicated by the reference numeral 31, comprises perimetral profiled elements 32 and additional profiled elements 34 which have the same profile and are simply obtained by bending.
  • each profiled element 32, 34 has a substantially I-shaped configuration in transverse cross section.
  • Holes 33 are defined on the two parallel wings 32a and 32b, 34a and 34b of said profiled element 32, 34 and are elongated in a direction which is parallel to the longitudinal extension of said profiled elements; said holes are used to mutually associate, by bolting, the profiled elements which constitute the reinforcement frame.
  • Said holes 33 are conveniently arranged, on each of said wings 32a, 32b, 34a, 34b, along two parallel rows, and the holes which belong to said two rows are mutually offset parallel to the longitudinal extension of the respective profiled element to facilitate positioning and assembly of the profiled elements and to obtain greater precision in angle couplings.
  • profiled elements 32 by virtue of their particular configuration, provides a greater flexural strength for the panel and an excellent fixing of the profiled elements in the concrete.
  • Holes 35 are conveniently defined in the core 34c of the additional transverse profiled elements 34 so as to provide a connection between the regions occupied by the layers 9. This connection makes the thermal conditions inside the panel uniform, particularly with regard to the distribution of humidity inside the panel.
  • the panel according to the invention fully achieves the intended aim, since by virtue of the thermally insulating or lightening layer substantially affecting the entire dimensions of the panel with no significant discontinuities, high performance in terms of thermal and acoustic insulation, resistance to fire and to the effects of weather is achieved without requiring any additional operation after installation and with no disadvantages of any sort due to different thermal expansions in the various parts which compose the panel.
  • the materials employed, as well as the dimensions can be any according to the requirements and to the state of the art.
