Definitions

  • the present invention relates to a self-supporting prefabricated structure for a stairwell and elevator shaft, and assembly method of said structure.
  • figure 1 shows a perspective view of a self-supporting prefabricated structure according to one embodiment of the present invention
  • figure 2 shows a view from above of a detail of the structure in figure 1 ;
  • figure 3 shows a cross-section view of a detail in figure 2 , along the section plane III-III in figure 2 ;
  • figure 4 shows a cross-section view of a detail in figure 2 , along the section plane IV-IV in figure 2 ;
  • figures 5A and 5B show cross-section views, along section planes perpendicular to each other, of the detail V in figure 1 ;
  • figure 6 shows a partial, longitudinal cross-section of the structure in figure 1 ;
  • figures 7-8 show transversal cross-section views, according to different embodiments of the structure in figure 1 .
  • reference numeral 4 globally denotes a self-supporting prefabricated structure for a stairwell and elevator shaft.
  • the prefabricated structure 4 comprises a plurality of mechanically joined panels 8 positioned so as to form a closed, hollow structure so as to define an elevator shaft 12 of a tubular shape having a mainly vertical extension Y-Y.
  • the panels 8 may be of the solid type; it is also possible to use multilayer panels wherein between the inner and outer panels, intermediate layers are provided for heat/noise insulation.
  • the panels 8 are bound to each other at the top, on contact arranging and mechanically assembling a rim 16 of a top extremity 20' of a first panel 8' with an inner lateral portion 24 of a top extremity 20" of a second panel 8", said inner lateral portion 24 facing the elevator shaft 12.
  • the top extremities 20', 20" of the panels 8', 8" are mechanically joined to each other by the direct interposition of plugs 28 and/or screws 32.
  • the top extremities 20', 20" of the panels 8', 8" adjacent to each other are joined by the alternate interposition, along the main vertical extension Y-Y, of plugs 28 and screws 32.
  • the plugs 28 are sunk into the panels 8 with the interposition of a binding agent, such as a resin.
  • the panels 8, on an outer side 36, opposite an inner side 38 looking directly onto the elevator shaft 12, comprise at least one step 40, firmly anchored to them at a first attachment extremity 44.
  • the steps 40 are bound to the panels 8 by threaded connection devices 48 passing through the first attachment extremity 44 of the steps 40 and through the entire thickness of the panels 8.
  • the threaded connection devices 48 are blocked in the panels 8 and in the steps 40 with the interposition of a binding agent, such as a resin.
  • a support plate 52 in neoprene is a support plate 52 in neoprene.
  • the prefabricated structure 4 further comprises joints 60 for the anchorage of the structure 4 to a foundation 64, the joints 60 being positioned at a lower extremity 68 of the panels 8, at the base 72 of the elevator shaft 12 to the foundation 64.
  • the joints 60 comprise a pair of plates 76 separated by a cavity 80 which houses the lower extremity 68 of the panels 8, the plates 76 being mechanically connected to the panels 8 by threaded connection devices 48.
  • the joints 60 comprise a rabbet 84 which connects the plates to each other 76 and which comprises threaded connection devices 48 on the side of each plate 76, to bind the joint 60 to the foundation 64, both from the inside 38 and from the outside 36 of the elevator shaft 12.
  • the joints 60 are positioned astride the joints 88 between two adjacent panels 8', 8", so that the plates 76 connect the adjacent panels 8', 8" to each other by means of threaded connection devices 48, at the lower extremities 68 of the panels 8', 8".
  • the prefabricated structure 4 is self-supporting so as to support itself without requiring mechanical restraints to the building which the structure is inserted in.
  • the only type of restraint required is the attachment of the structure to the relative foundation 64.
  • the method of assembly of the prefabricated structure 4 comprises the steps of assembling and mechanically joining panels 8 to each other to form a self-supporting, closed, hollow structure which defines an elevator shaft 12 of a tubular shape with a main vertical extension Y-Y.
  • At least one step 40 is then joined to the outer side 36 of the panels 8, firmly anchored to them at a first attachment extremity 44, for the creation of stairs joined externally to the elevator shaft 12.
  • the lower extremities 68 of the panels 8 are also provided with joints 60 for the anchorage of the structure 4 to a foundation 64 of a building,
  • the prefabricated structure so assembled is self-supporting and can therefore be raised, for example using a crane to then be lowered from above into the area chosen for the elevator shaft.
  • the present invention makes it possible to overcome the drawbacks present in the prior art.
  • the entire structure is pre-assembled separately from the building it is subsequently inserted in thereby avoiding the need for scaffolding in the area chosen for the stairwell.
  • the structure is self-supporting and statically independent of the rest of the building which it is inserted in.
  • it is an independent structure built separately and lowered from above into the chosen containment area.
  • connections between the various panels which define the stairwell and the attachments of the structure to the foundation ensure considerable mechanical resistance and means that the stairwell does not need to be anchored to the building after relative positioning inside it. This way, the mechanical separateness of the stairwell is conserved and it remains statically independent of the rest of the structure.
