Definitions

  • the invention relates to a modular panel, particularly suitable for the manufacture of reinforced concrete products.
  • pre- assembled panels have been known and used made up of the coupling of a central core of insulating material, suitably shaped, but substantially in sheets, and two flat metal nets which enclose the central core between them.
  • These panels in fact have a "sandwich structure" and are normally installed to create the walls and the ceilings of a building which, afterwards, is covered with concrete, creating a building that can become “bearing” to form walls and ceilings of a bui lding .
  • these walls and these ceilings are made in such a way as to be modular and easy to couple with other similar ones, by means of suitable joints, to make up a building technically defined as “with bearing partition walls” .
  • solutions have been devised that allow maintaining the central core slightly apart by a pre-set distance with respect to the metal nets, but fixed and substantially parallel with respect to these, so that this distance cannot change due to mutual slidings between the central core and the metal nets.
  • these known solutions consist in placing a number of spacer elements between the nets and the central core that are made integral with the nets and which are turned towards the central core so as to prevent contact between the nets and the central core and therefore leave the interspaces required for the cement to transit during the subsequent casting phase.
  • the modular panel basically comprises a sheet-shaped central core made of insulating material, and two flat net elements that contain it between them and which are arranged parallel to the two larger faces defined by the central core. Between the two flat nets, transversal stitching elements are provided that cross the central core and which have their respective ends made integral with both nets.
  • transversal elements are arranged obliquely with alternate inclination with respect to the parallel position of the net planes, in such a way as to create a web of transversal elements in the whole modular panel which, reciprocally crossing each other according to contrasting oblique directions and crossing the central core, keep this fixed at a predetermined distance from the nets, preventing any sliding with respect to these and thus preventing the nets from coming into contact with the sheet of insulating material.
  • the inclination and number of these transversal elements can vary according to need, its also being possible to achieve, according to a manufacturing variation of the patent EP 0701647, central core positions that are not symmetric with respect to the metal nets, meaning they are closer to one of the two with respect to the other.
  • transversal stitching elements are again considered between the metal nets arranged perpendicular to the faces of the central core, while the feet have predetermined lengths in relation to the distance to be kept between each net and the central core.
  • These spacer elements consist of a plurality of metal U-shaped reinforced concrete rods with two straight and parallel sections linked together at corresponding ends by a cross section which shapes a bend turned towards the central core: pratically, these U-shaped reinforced concrete rods have a substantially U shape.
  • These U-shaped reinforced concrete rods are fitted crossways in the central core until the bends are resting on the flat faces of this, keeping it distanced and stopped with respect to the metal net s .
  • the U-shaped reinforced concrete rods are fitted in the core in directions opposite to one another and are made integral with the respective metal nets in a known way, after the panel has been as Snapd .
  • a first drawback is that the manufacture of the transversal stitching elements arranged sloping with respect to the nets requires the nets to be purposely designed in relation to the inclination of the transversal stitching wire, because this must find at its ends the elements of the net with which to join: consequently, this special design determines a considerable waste of time as regards panel preparation.
  • a further drawback of this type of panel is that it is particularly difficult to manufacture due to the fact that the transversal joining wire has to cross a greater thickness of the central core thereby risking greater deviation from the theoretical trajectory, with the risk of not encountering the wire of the metal net on which it has to be welded.
  • a further drawback is that, however much the known panels can be reinforced in a differentiated way after the panel has been formed, meaning that areas of these that undergo higher stresses compared to areas that undergo less stress are strengthened, this operation is very complicated and hard to perform and, when all said and done, costly .
  • One object of the invention is to improve the state of the art.
  • a further object of the invention is to make a panel also suitable for use in the building trade that can be reinforced in a differentiated way in different areas of this after the panel has been formed or already installed.
  • a panel for the building trade comprising: a central core; two nets between which said central core is contained; retention means designed to retain said central core in a pre-established position with respect to said nets, characterized in that said retention means comprise areas for fitting reinforcement elements.
  • a building structure comprises a panel comprising: a central core,- two nets between which said central core is contained; retention means designed to retain said central core in a pre-established position with respect to said nets, characterized in that said retention means comprise areas for fitting reinforcement elements.
  • a method for the manufacture of panels comprising: arranging a substantially sheet-shaped central core of insulating material between two flat metal nets; placing in between said flat metal nets and said sheet-shaped central core retention means designed to retain said fixed central core with respect to said nets, characterized in that said placing in between comprises obtaining in said nets bends turned towards said central core, in such a way as to rest on the larger faces of this.
  • the panel and the method for the manufacture of panels therefore permit keeping the central core at predetermined distances with respect to the metal nets containing it, without the spacer elements crossing the central core and thus preventing the formation of undesired and harmful heat micro-bridges between the nets. Furthermore, the panel also permits reinforcing in a differentiated way different areas of the latter according to the stresses this has to withstand and keeping in position additional reinforcement rods without having to perform subsequent operations for their fixing.
  • Figure 1 is a schematic view from the top of a panel for the building trade according to the invent ion;
  • Figure 2 is a cross section schematic view of the panel for the building trade of Figure 1, taken along a plane II-II of Figure 1 ;
  • Figure 3 is a view on an enlarged scale and interrupted of a detail of a panel for the building trade in a second possible embodiment. EMBODIMENTS OF THE INVENTION.
  • a panel particularly suitable for the manufacture of reinforced concrete products, which comprises a central core 2, made of insulating material (see Figures 2 and 3) , which has a substantially flat sheet shape and which is closed in a sandwich between two metal nets 3, which are also flat, or substantially- such .
  • insulating material all the materials able to prevent heat and/or noise conduction.
  • the metal nets 3 comprise quadrangular meshes formed with iron rods 4 and 5 arranged according to directions substantially perpendicular with each other and which in the specific case are a transversal direction 4 and a longitudinal direction 5 respectively: consequently, hereinafter, the transversal rods will be indicated with the reference 4 while the longitudinal rods will be indicated with the re f erence 5.
  • bends 6 are obtained that are turned towards the central core 2, deforming, for example by bending, or stretching at least sections of at least part of said longitudinal rods 4; the obtained bends 6 therefore comprise two curved sections 7 joined together by a section 8 ready for resting on the central core 2 and which joins them together.
  • These bends 6 consequently shape, between the curved sections 7 and the joining sections 8, a number of cavities 9 in which can be placed, if necessary, further metal rods 10, arranged parallel to the rods 5.
  • the bends 6 can be obtained according to desired distributions in the metal nets 3, so that, for example, they are aligned with each other, so as to be able to fit a desired number of further rods 10 to reinforce the panel 1 in the desired areas and according to performed structural calculations .
  • the bends can be obtained by cutting segments of longitudinal rods 4 (or longitudinal rods 5) and shaping, for example by means of a bending operation, the cut segments so as to obtain the bends 106.
  • the latter further shape two curved sections 107 and a joining section 108 of these, ready to be rested on the central core 2, more precisely on two parallel and opposite larger faces 102 of this .
  • each bend 106 forms a hollow seat 109 inside which a further reinforcement rod
  • 11 and 12 are also envisaged that join the two nets 3 together, crossing the central core 2 in a substantially perpendicular direction.
  • the segments of rod 11 and 12 can be arranged sloping, as already indicated in the known technology .
  • the nets 3 can be made by arranging the transversal rods 4 between the central core 2 and the longitudinal rods 5 (see Figure 3) : this makes it easier to spread layers of mortar for covering the surfaces of the panels 1 when these are installed.
  • the fitting and fixing is also considered, between the meshes of the nets 3, of the further additional metal rods 13, these not being considered by the structural calculation, along which, the bends 6 or 106 are obtained.
  • the latter as is shown in the Figures 2 and 3, have the two curved sections 7 and 107 of the same length, or substantially of the same length, in such a way that the seats 9 and 109 are substantially closed at the side and that the further rods 10 that can be fitted in these cannot escape from them.
  • the shape of the bends 6 or 106 can be any, open or closed, according to the specific requirements that a person skilled in the field can assess for every need .
  • the panel 1 can have a profile shaped in such a way as to oppose the necessary support surface against the larger faces 102 of the central core 2 in order not to sink too much into the insulating material from which it is made in relation to the pressure applied during the realisation phases or during the transport and the installation of the panels themselves.
  • the panel 1 is made as follows: the two metal nets 3 are first of all prepared obtaining in these the bends 6 or 106, both by bending or by cutting and subsequent shaping a predetermined number of meshes of the metal nets 3.
  • the central core 2 is therefore positioned between two nets 3 and, by means of the bends 6 or 106, is kept at a pre-established distance from these, forming "IN" interspaces.
  • the segments of rod 11 and 12 are fitted crossways and these are made integral with the nets, for example, by means of weldings, bindings, gluing and other methods known to technicians in the field: this way the formation is completed of the structure of a panel 1, particularly, but not only, suitable for use in the building trade.
  • This panel 1 is installed and only before being covered with the concrete which envelops both the central core 2 and the nets 3 are the further reinforcement rods 10 fitted in the respective bends 6 or 106 chosen to reinforce the required areas of the panel 1.
  • bends 6 or 106 having a substantially closed perimeter, permit maintaining the further rods 10 in their position during the covering of the panel 1 with the concrete.
  • the panel 1 and the method for making panels according to the invention also permit forming and installing a double panel, meaning a panel that comprises two panels 1, made according to the present invention, placed parallel with each other and advantageously connected by further transversal joining elements to keep them united at a desired distance.
  • the double panel thus obtained acts in this case as a disposable reinforced and insulated form.
  • the procedure for installing the double panel is the same as that previously described for a single panel, meaning, when the double panels are positioned and joined to form the building, the concrete is cast inside the volume delimited by the two cores 2 so as to obtain a reinforced partition wall and therefore with bearing and greater structural characteristics than those of the single panels.
