Definitions

  • This supporting structure for a wall panel is used in the construction industry, particularly in the production of components for prefabricated buildings and building structures in general
  • building prefabrication is carried out by realising individual building components, such as beams, columns, trusses, closure panels and the like, which are then assembled on site using hydraulic binders to form the supporting and closing framework of the building.
  • these prefabricated panels have a perimeter edge adapted to abut against the perimeter edge of other panels, adjacent to them, to define a wall of a building.
  • finishing operations increase the uncertainty of lead times because, like all the operations on the building site, they are subject to delays.
  • prefabricated panels are not configured to interact mechanically with the other elements of the prefabricated building to increase their indeformability, as they are simply glued to the supporting structure by means of adhesives such as cement mortars, resins and the like.
  • the technical task underlying the present invention is to propose a supporting structure for a wall panel and a relative wall panel which overcome the drawbacks of the prior art mentioned above.
  • the supporting structure object of the present invention has a top edge, a bottom edge, and a pair of side edges.
  • This supporting structure comprises a bottom section bar defining the bottom edge, and an top section bar defining the top edge; wherein, each profile extends between the pair of side edges.
  • the supporting structure object of the present invention comprises a pair of tubular bodies parallel to, but not coinciding with, the side edges.
  • the pair of tubular bodies thanks to their hollow conformation, allows to accommodate reinforcing elements adapted to connect the supporting structure and the relative wall panel to a structural floor element and/or to a supporting element of a building, thus making the different elements of the building collaborate, increasing its indeformability and mechanical performance.
  • the object of the present invention is a supporting structure 200 for a wall panel 2000, and a relative wall panel 2000 for the construction of prefabricated buildings 1.
  • prefabricated buildings are understood to be all those building constructions made by assembling, preferably but not necessarily dry, a plurality of components.
  • Such prefabricated buildings 1 comprise a plurality of load-bearing beams 3000 that are interconnected to form the load-bearing framework. As shown in Figure 13 , at least part of these load-bearing beams 3000 are arranged parallel to a support plane 1a of the prefabricated building 1.
  • the prefabricated building 1 comprises at least one structural floor element 100 configured to be arranged on at least one pair of load-bearing beams 3000, oriented parallel to the support plane 1a, to define at least part of the floor of a prefabricated building 1.
  • the structural floor element 100 is configured to be interposed between at least two load-bearing beams 3000 so as to be at least partially recessed between the latter, as shown in Figure 13 .
  • the structural floor element 100 comprises a frame 110 configured to abut on the load-bearing beams 3000 to support the structural floor element 100.
  • such a frame 110 is made of metal, more preferably steel, or aluminium.
  • the structural floor element 100 has a seat 120 extending between an upper plane S and a lower plane I that are parallel to each other.
  • the seat 120 is configured to accommodate one or more layers 130 of a floor.
  • the frame 110 is arranged peripherally with respect to the seat 120, i.e. the frame 110 surrounds the seat 120, limiting it laterally.
  • the frame 110 has a plurality of sides L which are interconnected and peripherally delimiting the seat 120.
  • the frame 110 comprises four sides L, optionally parallel to each other, i.e. it has a quadrangular shape. Consequently, the seat 120 delimited laterally by the frame defines a volume in the form of a parallelepiped, usually quadrangular but potentially with a plurality of sides and angles, within which the one or more layers 130 constituting the floor can be placed.
  • the frame 110 comprises a first flange 111 projecting into the seat 120 and lying in the lower plane I.
  • the first flange 111 extends into the seat 120 at the lower plane I by realising a cantilevered shelf adapted to receive, by resting, one or more layers 130 of the floor, as shown in Figure 4 .
  • the first flange 111 is therefore configured to support the one or more layers of floor 130 which are inserted into the seat 120.
  • the frame 110 further comprises a second flange 112 projecting outwards from the seat 120, i.e. in the opposite direction with respect to the first flange 111.
  • the second flange 112 is configured to rest on at least one load-bearing beam 3000 to support the structural floor element 100.
  • the structural floor element 100 by means of the first and second flange 111, 112, allows to contain and support the one or more layers of the floor.
  • the second flange 112 lies in the upper plane S, so that when it abuts on the support beam 3000 the structural floor element 100 is completely recessed. This allows to reduce the thickness of the floor of the prefabricated building, so as to place the one or more layers of the floor between the load-bearing beams 3000.
  • the frame has an S-shaped section; that is, it has main portion 110a extending between the lower I and the upper S plane by connecting the first and second flange 111, 112 which project from the main portion 110a in opposite directions.
  • the first flange 111 comprises a plurality of first flange portions 111a, each of which is associated with a respective side L of the frame 110.
  • the plurality of first flange portions 111a peripherally surround the seat 120.
  • the first flange portions 111a are configured to simultaneously contact the one or more layers 130 of the floor to support them stably and arrange them inside the seat 120.
  • the second flange 112 comprises a plurality of second flange portions 112a, each of which is associated with a respective side L of the frame 110.
  • the plurality of second flange portions 112a peripherally surround the seat 120.
  • the second flange portions 112a are configured to abut on respective load-bearing beams 3000 to stably support the structural floor element 100 and firmly fix it to the load-bearing framework of the prefabricated building 1.
  • the structural floor element 100 comprises first stiffening means 140 adapted to increase its mechanical performance, in particular its stiffness and non-deformability.
  • first stiffening means 140 are configured to connect two adjacent sides L of the frame 110, i.e. two adjacent sides L having a common end.
  • the first stiffening means 140 comprise a plurality of plates 141 connected to the frame 110.
  • each plate is arranged in the lower plane I and is connected to two respective adjacent sides L of the frame 110.
  • each plate is triangular in shape and has a pair of catheters respectively solidly connected to first flange portions 111a associated with adjacent sides of the frame 110.
  • the structural floor element 100 preferably comprises second stiffening means 150 adapted to further increase its mechanical performance.
  • the second stiffening means 150 are configured to increase the load-bearing capacity of the structural floor element 100, i.e. the maximum load it is capable of supporting.
  • the second stiffening means 150 are configured to connect two sides L of the frame 110 arranged on opposite sides of the seat 120. Preferably, the sides L connected by the second stiffening means 150 are parallel.
  • the second stiffening means 150 comprise a plurality of bars 151 arranged in the seat 120 and extending between two opposite sides L of the frame 110.
  • each bar 151 has a pair of ends 151a connected to respective opposite L sides of the frame.
  • the ends 151a of each bar are solidly connected to respective first flange portions 111a associated with opposite sides L of the frame 110a.
  • the bars 151 are arranged parallel to each other and equidistant. Even more preferably, the bars 151 are arranged parallel to one side L of the frame 110. It is worth noting that the greater the desired load-bearing capacity of the structural floor element 100, the greater the number of bars 151 required, and consequently the smaller the spatial distancing between one bar 151 and another.
  • the structural floor element 100 comprises an anchoring element 160 connected to the second flange 112 and projecting from the upper plane S on the opposite side with respect to the lower plane I.
  • Said anchoring element 160 is configured to be coupled to a prefabricated wall panel 2000. More details about the wall panel 2000 and the connection to the structural floor element 100 will be provided in a later part of the description.
  • the anchoring element 160 comprises an internally hollow box-shaped profile 161 having a bottom wall 162 fixed to the second flange 112 of the frame 110, a pair of side walls 163 projecting from the upper plane S on the opposite side with respect to the lower plane I, and an upper wall 164.
  • the opening 165 extends along a main extension direction P-P and has: an insertion section 165a, configured to allow the introduction of the reinforcing element 300 into the opening 165; and a locking section 165b, configured to lock the movement of the reinforcing element 300 along a direction orthogonal to the upper surface S as well as along the one transversal to the direction P-P.
  • the insertion section 165a has an extension perpendicular to the main extension direction P-P of the opening 165 greater than the locking section 165b. Therefore, the insertion section 165a has a larger cross section than that of the locking section 165b, to allow inserting the reinforcing element 300 into the opening 165.
  • the insertion section 165a and the locking section 165b are arranged in series along the main extension direction P-P and connected to each other. In this way, when the reinforcing element 300 is inserted into the insertion section 165a of the opening 165 and subsequently translated along the main extension direction P-P inside the locking section, it is constrained along a direction orthogonal to the surface S, given the smaller cross section of the locking section 165b.
  • the prefabricated building 1, shown in section in Figures 12 and 13 further comprises at least one wall panel 2000 configured to be connected to the structural floor element 100 and other wall panels 2000, in order to make the closing framework of the prefabricated building 1.
  • Such a wall panel 2000 shown in Figure 6 extends along a vertical direction V-V between an top edge 2002 and a bottom edge 2001; and along a horizontal direction O-O, perpendicular to the vertical direction V-V, between a pair of side edges 2003.
  • the wall panel 2000 also has a pair of surfaces 204, shown in Figure 9 , arranged on opposite sides of the panel 2000 and joining the bottom and top edge 2001, 2002 along the vertical direction V-V, and the pair of side edges 2003 along the horizontal direction O-O.
  • the lower and top edge 2001, 2002 extend parallel to the horizontal direction O-O and the pair of side edges 2003 extend parallel to the vertical direction V-V.
  • the wall panel 2000 is mainly rectangular but may assume a different shape if the edges 201, 202 and 203 do not extend parallel to the horizontal O-O and vertical V-V direction.
  • the wall panel 2000 may assume different geometric shapes with 3 or more sides.
  • Said wall panel 2000 comprises a plurality of layers 2100 having thermal and/or sound insulating properties arranged between the pair of surfaces 204.
  • the wall panel 2000 further comprises a supporting structure 200 arranged between the pair of surfaces 204 delimiting the panel.
  • the supporting structure 200 is integrated into the plurality of layers 2100 and is thus at least partially covered by the latter.
  • This supporting structure 200 in addition to the intrinsic function of stiffening the wall panel 2000, is configured to facilitate and speed up the construction operations of the prefabricated building.
  • the supporting structure 200 is configured to connect the wall panel 2000, inside which it is integrated, to the other structural elements of the prefabricated building 1, such as structural floor elements 100 and other wall panels 2000, without the need to use adhesives.
  • the supporting structure 200 for prefabricated wall panels 2000 will be described in detail below.
  • This supporting structure 200 is shown individually in Figures 6-8 , and integrated into the wall panel in Figures 9-10 and 12-13 .
  • the supporting structure 200 extends along the vertical direction V-V between the top edge 202 and the bottom edge 201; and along the horizontal direction O-O between the pair of side edges 203.
  • the bottom edge 201, the top edge 202, and the side edges 203 coincide with the respective edges of the wall panel 2001, 2002 and 2003 when the supporting structure 200 is integrated into the wall panel 2000.
  • the bottom section bar 210 is configured to connect the supporting structure 200 at the bottom, and thus the wall panel 2000, to another wall panel 2000 or a structural floor element 100, as shown in Figure 12a .
  • the supporting structure 200 also comprises an top section bar 220 defining the top edge 202.
  • the top section bar 220 extends along the entire top edge 202 between the pair of side edges 203.
  • the top section bar 220 is configured to connect the supporting structure 200 at the top, and thus the wall panel 2000, to the supporting structure 200 of another wall panel 2000 or a load-bearing beam 3000.
  • the bottom and top section bar 210, 220 define a respective cavity 210a, 220a configured to connect the supporting structure 200 to a structural floor element 100 or to another supporting structure 200. More preferably, the bottom and top section bar 210, 220 have a U-section.
  • the bottom section bar 210 has a shape complementary to the anchoring element 160 of the structural floor element 100 described above. In this way, it is possible to insert the anchoring element 160 inside the cavity 210a defined by the bottom section bar 210 to connect the supporting structure 200, and thus the wall panel 2000, to the structural floor element 100.
  • the supporting structure 200 comprises an insert 211 arranged in the cavity 210a defined by the bottom section bar 210 and configured to damp vibrations.
  • an insert 211 is made of a polymeric material, such as solonic lactic rubber.
  • the insert 211 is interposed between the bottom section bar 210 and the anchoring element 160 to damp the vibrations between the bottom edge 201 defined by the bottom section bar 210 and the structural floor element 100.
  • the insert 211 has a U-section that can be inserted inside the U-section of the bottom section bar 210 as shown in Figure 7 .
