  • Phase B turn the locking key 40 by 45° (or other degree according to the need of the nodal system 30 ) so as to obtain the locking of the locking key 40 and the alignment of the holes 48 of the wings 42 with the holes 18 , 18 ′ of the vertical wall 11 , 11 ′ of the beams 10 , 10 ′; proceed to fasten (locking key—beams) by means of the suitable retention means 108 .
  • Phase C close the nodal system 30 inserting a further vertical locking element 23 , 50 , having an aperture 51 , on the locking key 40 , so the shape element 43 of the locking key 40 penetrates the aperture 51 of the further vertical locking element 23 , 50 ; turn the further vertical locking element 23 , 50 by 45° (or other degree according to the need of the nodal system 30 ) so as to obtain the locking of the further vertical locking element 23 , 50 and the alignment of the holes 56 , 26 , provided on the further vertical locking element 22 , 50 , with the holes 16 , 16 ′ of the upper base 12 , 12 ′ of the beams 10 , 10 ′; proceed to fasten (further vertical locking element—beams) by means of suitable retention systems 106 .
  • Each node 101 can have various horizontal extension configurations, depending on the use of more or less truncated beams 10 ′ (which preferably realize a closing point of the structure) of more or less beams 10 . (which preferably realize an extension point of the structure).
  • Some of the possible configurations of the node 101 shown in FIG. 7 , are, for example:
  • the figures from 8 b to 8 l show a method of assembly of a module 120 of a load-bearing structure 100 .
  • the method of assembly of a module 120 of the load-bearing structure 100 comprises the following phases:
  • the figures from 8 a to 8 l show a method for assembling a load-bearing structure 100 .
  • the method of assembly of a load-bearing structure 100 comprises the phases of realizing a plurality of modules 120 (figures from 8 b to 8 l ).
  • the method of assembly of a load-bearing structure 100 also comprises, before the phase of realizing a plurality of modules 120 , the following phases:
  • the parts making up the nodal system can be made in any metal alloy, preferably iron or steel, in wood and by-products, in composite metal and wood material, in plastic material, in glass.
  • metal alloy preferably iron or steel
  • wood and by-products in composite metal and wood material
  • plastic material in glass.
  • such elements are made from sustainable material and recyclable using traditional industrial processes.
  • the elements making up the nodal system (locking key and locking element) have special finishes against atmospheric agents and time wear, or anything else invasive or deteriorating in relation to the type of use and to the chosen material.
  • the nodal system can also present itself in different forms, but it is essential that the technical locking solution be realized by the compound presence of two different forms (locking key shape element—opening of locking element) perfectly penetratable in an input solutions and subsequently rotatable in an output solution which determines its locking.
  • Such locking is further stiffened by a retention system of various kind and form (e.g., screws and bolts), including deriving from a traditional lock preferably fitted on the locking key, so as to ensure greater protective safety against tampering by third parties or access to the central system, besides acting as a further stiffening of the structure.
  • the lock could comprise one or more mobile components, preferably flexible, and thus have the task of permitting or preventing the oscillation of the nodal system.
  • the drilling of the various component elements be dimensionally constant so as to allow a perfect alignment of the holes for fitting the various elements, and a simplification of the relative types of retention means.
  • a nodal system for load-bearing structures permits the fast assembly and disassembly of the components and, at the same time, provides excellent resistance to the static stresses of the structure.
  • a nodal system for load-bearing structures permits a reconfiguration and a different directionality of the beam/pillar components according to the requirements in question.
  • a nodal system for load-bearing structures permits extensions/retentions of the single modules of the load-bearing structure without necessarily intervening with changes to the entire structure as a whole.
  • a nodal system for load-bearing structures ensures simplicity of construction and rapidity of assembly.
  • a nodal system for load-bearing structures implies less construction effort and less movement of weights.
  • a nodal system according to the present invention does not require on-site machining operations but only the sequential assembly of the components, and allows using non-qualified personnel, with consequent cost cutting.
  • a nodal system according to the present invention consisting as it does of just a few elements, identical, which can be coupled or stacked, permits the optimization of the packaging and transport spaces of the elements themselves, as well as the removal of such elements without incurring damage to the materials making it up, such as to force them to be replaced.
  • a nodal system permits simplifying current worksite transport and storage logistic systems and/or completely eliminating storage areas, inasmuch as the structure can be assembled a little at a time as the means of transport used is gradually emptied.
  • a nodal system according to the present invention being modularly implementable and easy to transport, is also particularly suitable for marketing through “type” structure assembly kits and/or their predefined implementations.
  • Such a marketing system can help simplify the management phases of the production warehouse and automated shipment, providing a large saving in terms of time, costs and organization, with consequent reduction of environmental impact and direct and indirect pollution.
  • a nodal system according to the present invention being repeatable in the load-bearing structure and immediately assemblable, can be immediately used on site without large storage spaces being required.
  • a nodal system according to the present invention permits a considerable reduction in environmental impact and direct and indirect pollution.
  • a nodal system is suitable for the realization of: commercial buildings, dwelling houses; public buildings and spaces; frameworks for fire-escape ladders, for lifts; gangways for bicycle-pedestrian use, for railway/road use, for lean-to roofs, for structural car-parks; gazebos; bridges; grandstands; stands; stages; platforms; greenhouses; metal roofs; containment structures for excavation works; accessory structures for industry in general, for telecommunications, for renewable energies, for serving a non-invasive building system adaptable to risk contexts, for laminated beam systems for roofs, more in general, to replace traditional construction systems without any limits as regards use, fruition, extension and intended use.
  • a nodal system according to the present invention is suitable for being combined with traditional structural systems and compatible materials, such as tensile structures or the like and/or a consequence of a pre-existing structure, e.g., being used in the realization of added storeys, extensions and internal, external and underground structural consolidations of traditional buildings.
