Definitions

  • the present invention concerns a beam for attaching a cantilevered structure, in particular a self-supporting beam made of steel or mixed steel-concrete which can be used for the construction of self-supporting cantilevered terraces for buildings.
  • the invention also concerns a self-supporting terrace comprising said beam.
  • modular systems which comprise mixed steel-concrete beams and pillars and which can be used in various fields of application and for the construction of various building works, for example in industry, infrastructures, in the construction of residential or commercial buildings, in the construction of health facilities, car parks or other.
  • the construction of a cantilevered structure to be prepared in the work being built provides to connect this cantilevered structure to one of the edge beams of the load-bearing structure of the building.
  • connection of a cantilevered structure to a self-supporting beam can entail various disadvantages, for example the fact that the position of the cantilevered structure is difficult to adjust with respect to the beam and therefore with respect to the facade of the building.
  • Another disadvantage lies in the lack of versatility of known beams, that is, the fact that normally a specific beam can be combined with a specific cantilevered structure, for example a simple structure of metal structural work or a prefabricated reinforced concrete structure, but it is only with difficulty that these solutions can be adopted with the same beam.
  • the beams used are mainly stressed by torsion stresses and their behavior, when subjected to torsion moments, as in the case of attaching cantilevered structures, can be improved.
  • heat differences can be created that reduce the durability of some parts of the building, such as finishes, plasters and masonry infills.
  • document EP3112541 describes an assembly unit for a terrace which comprises a first assembly element suitable to be connected to the external part of a building and a second assembly element attached to the terrace and suitable to be attached to the first assembly element.
  • one purpose of the present invention is to provide a beam for a cantilevered structure, in particular a self-supporting beam, which is versatile and can therefore be used for any cantilevered structure, for example a cantilevered structure of metal structural work, concrete or other.
  • Another purpose of the present invention is to provide a beam for a cantilevered structure by means of which the position of the cantilevered structure can be adjusted quickly and precisely with respect to the beam.
  • Another purpose of the present invention is to provide a beam for a cantilevered structure which supports torsion stresses more effectively and is more stable than known beams.
  • Another purpose of the present invention is to provide a beam for a cantilevered structure by means of which it is possible to improve the behavior of the work in which it is used, in particular in relation to the thermal stresses to which this work is subjected, in particular by means of providing effective thermal breaks.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a beam for attaching a cantilevered structure comprises at least one elongated body provided on at least one side with a plurality of attachment bars which are configured to be inserted into corresponding holes made on at least one corresponding side of the structure; the bars are provided with adjustment elements mobile along such bars so as to vary at least one distance of attachment of the structure with respect to the beam.
  • the present beam for attaching a cantilevered structure thanks to the presence of bars and adjustment elements, is extremely versatile, and therefore it can be used for any cantilevered structure whatsoever, for example a cantilevered structure made of metal structural work, made of concrete or other. Furthermore, by using the present beam, the position of the structure attached cantilevered can be adjusted quickly and precisely with respect to the beam.
  • the bars can be grouped on attachment plates distributed with a regular pitch along the side of the elongated body.
  • Each of the plates can comprise two pairs of bars disposed parallel.
  • the elongated body can be tubular and configured to be filled with reinforcing material, such as structural concrete or other.
  • the beam thus made supports the torsion stresses more effectively and is ultimately more stable than known beams.
  • the bars are threaded, and the adjustment elements can comprise at least a first nut configured to be positioned, during use, on one side of a side of the cantilevered structure, and a second nut configured to be positioned, during use, on the opposite side of such side of the cantilevered structure.
  • the beam can also comprise a series of holes configured for the insertion of reinforcement structures or suchlike, and positioned on one side of the elongated body different from the side where the bars are positioned.
  • the holes can be distributed with a regular pitch along such side of the elongated body.
  • the beam can comprise at least one end shaped as a tooth or suchlike.
  • the present invention also concerns a self-supporting terrace comprising a structure attached cantilevered to a beam as defined above.
  • the structure attached cantilevered can be separated from the beam by a distance that defines a hollow space.
  • a beam 10 according to the present invention and configured for the attachment of a cantilevered structure 11 comprises at least one elongated body 12 and attachment means 55 for attaching the structure 11 to the elongated body 12.
  • the attachment means 55 are disposed on at least one side 13 of the elongated body 12 and they comprise a plurality of attachment bars 14, for example threaded bars, configured to be inserted into corresponding holes 15 made on at least one side 16 of the structure 11.
  • the bars 14 are provided with adjustment elements 18 and 19 which can be screwed or unscrewed along the bars 14 so as to vary at least a distance D of attachment of the structure 11 with respect to the beam 10.
  • the bars 14 can be grouped on attachment plates 22 distributed with a regular pitch P1 along the side 13 of the elongated body 12.
  • Each of the plates 22 can comprise two pairs of bars 14 disposed parallel.
  • the adjustment elements 18 and 19, see in particular fig. 2 can comprise at least a first nut 18 configured to be positioned, during use, on one side of the side 16 of the structure 11, and a second nut 19 configured to be positioned, during use, on the opposite side of the side 16 of the structure 11.
  • the attachment means 55 comprise an attachment member 56 able to be removably associated with the outside of the elongated body 12 and configured to be attached, in turn, to the structure 11.
  • the attachment member 56 comprises a bracket 57 in the shape of an inverted U configured to be disposed straddling the elongated body 12.
  • the bracket 57 comprises an upper side 59 and two parallel lateral sides 60, 61 which develop from the upper side 59.
  • the structure 11 is connected to one of the two lateral sides 60, 61 by means of attachment elements (not shown) of a known type and which will not be described in detail.
  • the attachment elements can comprise screws, bolts, threaded bars, interlocking portions, or welded connections.
  • connection element 62 suitable to keep the bracket 57 adhering to the elongated body 12.
  • the elongated body 12 can be tubular and configured to be filled with reinforcing material M, such as structural concrete or other.
  • the shape of the elongated tubular body 12 can be any shape whatsoever, it can have for example a square or rectangular section, as shown by way of example, or also a different polygonal section or even a circular or elliptical section.
  • the end of the beam 10 can be shaped with a toothed shape that resembles a rack, or suchlike, which fixes to a similar profile that is integrally welded to a pillar that supports the beam itself.
  • the beam 10 can also comprise a series of holes 20, made on the elongated body 12, configured for the insertion of reinforcement structures or suchlike and positioned on one side 21 of the elongated body 12.
  • the holes 20 are made on a side of the elongated body 12 which is different from the side 13 where the bars 14 are positioned.
  • the holes 20 can be distributed with a regular pitch P2 along the side 13 of the elongated body 12.
  • the pitch P2 can be the same as the pitch P1.
  • Figs. 5 to 8 show two examples of structures 11 and 17, each comprising a projecting part 34 which can be attached to the present beam 10.
  • the beam 10 as can be observed, can be positioned at the ends on supports 23 which are associated with a pair of pillars 24, also visible in figs. 3 and 4 .
  • the pillars 24 can be parts of a building 25 that comprises other beams 26, for example steel beams or mixed steel-concrete beams.
  • the structure 11 or 17 can comprise a hollow space 27 with an adjustable extension made between the beam 10 and the side 16 of the projecting part 34 which is attached to the beam 10.
  • the hollow space 27 By means of the hollow space 27 it is possible to substantially make a thermal break with an adjustable thickness, thus improving the thermal behavior of the building 25.
  • the hollow space 27 there can be interposed layers of insulating material, possibly shaped around the point connections.
  • the structure 11 can comprise a lower panel, a covering 28 and an upper fretted panel 29.
  • the structure 17, see figs. 7 and 8 can comprise a lower panel, a covering 30 and an upper fretted sheet 31.
  • the use of the bars 14 and of the adjustment elements 18 and 19 allows for a great versatility of application of the present beam 10; in fact, it is possible to make the structure 11 or 17 either with simple metal structural work or with more traditional prefabricated solutions in reinforced concrete and terracotta coated intrados, such as "predalles" type slabs or suchlike.
  • the pairing and attachment of the cantilevered structure 11 or 17 therefore occurs in correspondence with the bars 14, which are preferably located at a regular pitch PI, and their disposition is designed to allow the alignment and adjustment of the terrace both in a direction X and also in a direction Y, see for example fig. 5 , with respect to the facade of building 25.
  • the beam 10 can be made of steel or mixed steel-concrete and, unlike the solutions available on the market, offers the possibility of being designed with a desired number of bars 14 along its length, so as to substantially have no limits in capacity load.
  • the present invention also concerns a method for attaching a structure 11, 17 cantilevered to a beam 10.
  • the method provides a step of filling the elongated body 12, in which the latter is filled with reinforcing material M.
  • the method also provides an attachment step, in which the structure 11, 17 is attached to the elongated body 12 by means of the attachment means 55.
  • the attachment step provides to attach the latter to the structure 11, 17.
  • the attachment step provides both to attach the latter to the structure 11, 17 and also to associate the attachment member 56 with the elongated body 12.
