Definitions

  • the present invention concerns an integral prefabrication system with frame structure featuring finished lightweight components.
  • the frame systems create, by means of beams, pillars and floors, the structural skeleton of the building which must then be completed on site with the filler panels, partitions and floor consolidation castings.
  • the frame systems are therefore not "global" as the prefabrication has to be integrated with completion work on site.
  • the outer and inner walls have the job of sustaining the floor and creating a box-shaped structure forming the room module, the disadvantages being that it is not possible to alter the distribution from floor to floor, consequently it is not possible to design the ground floor as required, on piloty and underground garage.
  • the concrete supporting elements make the structure heavy and therefore anti-economic especially in countries where the cost of materials affects the final cost to a far greater extent than labour costs.
  • Document US 3 803 788 A discloses an integral prefabrication system according to the preamble of claim 1, wherein a building construction in which walls are formed of prefabricated elements is provided.
  • documents US 3 710 527 A , US 4 413 454 A and US 3 812 637 A disclose integral prefabrication systems according to the preamble of claim 1.
  • the aim of the present invention is to produce an integral prefabrication system with frame structure featuring finished lightweight components that overcome the above-mentioned disadvantages.
  • the system of the invention uses walls that create an apartment module and not a room module; the walls are finished and incorporate a frame structure and a lightweight internal area to reduce the weight as far as possible with channels which can also be used.
  • ducts for wiring and other installations can be made inside them and connected to the vertical wall channels. All the components are finished and no on-site casting is required during assembly, only mortar injections.
  • the system is defined integral in the sense that the building is constructed 100% with finished lightweight prefabricated components, maintaining the static advantages of the frame structures and the finishes of the supporting panel structures, but eliminating the negative aspects of the two structures; the system is therefore lightweight, economic and versatile and is competitive both for single-family terraced buildings and for buildings with over 20 floors.
  • the integral prefabrication system with frame structure featuring finished lightweight components of the invention comprises firstly a component 11 called partition wall.
  • the internal partition wall 11 fitted at intervals on the apartment module to sustain the floor, is cast in vertical formworks to obtain the two finished outer surfaces and consists of a flat frame, made of two end pillars 12 and an upper beam 13, and a lightweight wall with vertical holes 14, obtained by means of special tubular formworks that contract elastically for extraction.
  • the flat columns or pillars 12 have dimensions that can be adjusted to static requirements, and contain a sheath (a sheet metal tube) 15 which is injected.
  • the injection ensures distribution of the loads from floor to floor and vertical continuity of the reinforcing bars inserted one on top of the other.
  • the tubes that form the lightening holes 14 can be positioned as required and have fixed and modular dimensions. They can also be used to obtain continuous vertical channels for wiring, ventilation and fume expulsion, and to provide vertical structural continuity with continuation of the reinforcement.
  • the partition walls permit the creation of walls with different total thickness for the variable loads due to the different number of floors (in general, purely as an example, 15, 20, 25 cm for holes of 10 cm * 55 cm).
  • Another component of the system of the invention is the filler panel 16 shown in figure 3 .
  • the panel is characterised by a top beam 17 which rests at the level of the partition wall 11 on its end pillar 12.
  • the top beam 17 has the following functions:
  • the partition wall - filler panel node is provided by the insertion of a vertical bar 18 that enters the sheath 15 of the partition wall 11 and crosses a stainless steel loop 19, so that it is not necessary to make holes in the formworks, with ropes coming out of the top beam 17.
  • Another component of the system of the invention is the floor component 20 of figure 4 .
  • the horizontal hole of the floor can be made not only by means of polystyrene blocks but also, like the wall holes, via special tubular formworks which contract elastically for extraction based on exactly the same concept as those of the partition walls.
  • the horizontal holes of the floors are connected to the vertical holes of the partition walls thus permitting distribution of the wiring and other installations both horizontally and vertically.
  • the floors are fixed to the partition wall not by means of the usual on-site casting but by means of a mechanical connection 40 ( fig. 1 ), while on the joining line of two elements one, two or three welded connections 24 can be performed so that the intrados of the floors creates a rigid horizontal surface.
  • the panel 21 which is independent of the floor statics, can be positioned at the end of assembly and can be subsequently raised like a trapdoor to access the wiring and other installations or can be entirely eliminated to obtain, for example, an earth container flush with the floor.
  • the floor and the panels can have a finished surface which, once laid, constitutes the finished floor of the house, or the floor can be used as a base for laying a self-levelling material on which an impact noise insulation layer and then tiles, carpet, linoleum etc. are glued to provide dry flooring.
  • FIG. 5 shows a roofing floor 25, belonging to the prefabrication system of the invention.
  • the element has a flat intrados constituting the ceiling of the last floor, while the extrados consists of a covering slab with transverse and longitudinal pitch of 15%, in order to create:
  • An element 41 can also be provided featuring a flat front panel that conceals the pitched ventilated roof behind, as shown in figures 6-7 .
  • Figures 8-9 show particular views of a portal frame structure 26, belonging to the prefabrication system of the invention.
  • the pillar with collar has one fixed and one variable dimension with the possibility, therefore, of obtaining "blade" pillars ranging, for example, from the minimum section of 25 cm x 40 cm to a section of 40 cm x 60 cm or 25 x 200.
  • Figure 10 shows a bracing element 27 consisting of partition walls that form the stairwell or lift shaft.
  • partition wall holes can be through holes in order to contain the vertical reinforcement cage 28 which continues from floor to floor.
  • the partition walls are interconnected by the insertion of bars 18 in the protruding steel wire rope loops 19 and by further injection as for the top beam of the panels.
  • Figure 11 shows a bathroom shell 29 belonging to the prefabrication system of the invention.
  • the bathroom shell 29 contains a fully accessorized bathroom, equipped and finished to provide integral prefabrication by components.
  • the shell is made of a concrete element completely closed on the six sides, self-supporting, but able to perform also a bracing function for single-floor constructions during assembly. Its reduced height means that a storage compartment can be obtained in the upper part between the shell and the ceiling.
  • Figure 12 shows a staircase 30, to make the prefabrication system integral.
  • the staircase 30 consists of three overlapping finished elements consisting of a tubular structure fitted with the overhanging steps which constitutes the stair supporting element inside which it is also possible to install a lift by removing the floor slab.
  • the three inter-floor elements are positioned one on top of the other and consolidated by injection of sheath reinforcement, as for the partition walls.
  • a stair unit 30 is produced, complete with landings, which can be fitted either inside or outside the building and is totally independent from the static point of view.
  • the steps can be made with finished risers and treads so that, once the component is fitted, there is no need for any further work.
  • connection devices 31 consisting of stainless steel loops.
  • connection devices are made by inserting in the formwork retrievable magnetic elements which pull out of the wall, at the required intervals, a loop 19 made of stainless steel wire rope which does not require holes in the side and which, due to its flexibility, permits easy positioning of two adjacent walls during assembly.
  • the magnetic element that holds the loop is positioned in a semi-circular recess which permits, after on-site insertion of a reinforcing bar 18, overhead injection of shrink-resistant mortar into a recess 32.
  • the protruding loops provide both the insulated connection of the walls that constitute the earthquake-proof structure and the joints in the top beam of the filler panels.
  • figure 17 shows an exploded axonometric view of a structure, indicated overall by reference number 100, made with the prefabrication system of the invention.
