Definitions

  • This invention falls within the building sector, specifically in the area of self-supporting sandwich panels with quick and innovative fittings and thoroughly equipped with means for installation, namely water, electricity and telecommunications networks.
  • prefabrication solutions were invented which, even today, are reflected in the construction sector in Portugal, with a greater incidence in industrial buildings and/or warehouses. It is a pre-established set of different structural elements in reinforced concrete which are manufactured by groups, in factory environment, on a suitable installation, based upon large moulds. Already on site, the prefabricated elements are simply assembled according to the envisaged sequence, with the use of lifting means, which as a general rule are very powerful, depending on the weight of the components and, therefore, quite expensive.
  • the exterior walls can be the traditional ones (masonry) or they can be made up of panels produced through industrialised processes of significant durability, where thermal and acoustic insulation are essential.
  • Interior walls and partitions are, as a general rule and depending on the vocation of the building, executed by conventional processes and/or by more evolved processes (plasterboard with acoustic insulation, etc.).
  • symbioses of systems such as metal structures and prefabricated concrete panels can be created and installed using cranes. More recently, the characteristics of materials with more than 40 years of existence have been used, but without much success due to the initial inability to stabilise the material (then known as YTONG) and prefabricated panels in AAC (Autoclaved Aerated Concrete) have thus been created, which present a resistant function, low weight, thermal comfort and fire resistance. With an apparent success in terms of speed and quality, it has been found that the amount of material waste was enormous, with an unsustainable environmental impact.
  • the patent document WO 2017/182946 discloses a panel system based on the use of calcium silicate panels together with a "filling" of "styrofoam” balls with a cement grout, thus obtaining a panel with a generous thickness (about 15 cm), which are interesting weight characteristics associated to a good thermal insulation. Equipped with a tongue-and-groove type fitting devices, the system is, however, not self-supporting, always requiring additional assembling and fastening arrangements based on starter rails and "gluing" of the panels with cement slurry.
  • This invention solves all the technical problems identified, since it relates to lightweight, highly durable, modular sandwich self-supporting panels, with certain specificities described throughout this patent document.
  • this invention has the following advantages comparatively to the state of the art:
  • This invention relates to self-supporting structural panels with built-in infrastructure and the respective system of self-supporting structural panels.
  • the system of panels which is the object of this invention consists of a plurality of panels, however it is essential that it comprises at least two panels (P) which are connected and fixed, in such a way that they are shiftedly arranged with respect to each other as often as required by the idealised construction, and will be finalised by means of the preferred embodiments of the panels, in particular, capping panels for façade fixing (PRF) (floors and ceilings) and vertical panels for façade fixing (VPFF) (for exterior walls).
  • PRF façade fixing
  • VPFF vertical panels for façade fixing
  • the system which is the object of this invention consists of at least two panels (P), wherein each of the panels (P) comprises:
  • This invention relates to self-supporting structural panels with built-in infrastructure and the respective system of self-supporting structural panels.
  • the system of panels which is the object of this invention consists of a plurality of panels (P), however it is essential that it comprises at least two panels (P), which are connected and fixed, in such a way that they are shiftedly arranged with respect to each other as often as the idealised construction requires, and will be finalised by means of preferred embodiments of the panels, in particular, capping panels for façade fixing (PRF) (floors and ceilings) and façade vertical panels (PVF) (for exterior walls).
  • PRF façade fixing
  • PVF façade vertical panels
  • panel (P) either for vertical (VP) or horizontal (HP) positioning
  • capping panel for façade fixing (PRF) floors and ceilings
  • façade vertical panel (PVF) for exterior walls
  • the panels (P) have two faces (1), which preferably will be in magnesium oxide as it is a non-flammable and highly resistant material with fire protection. Other finishing materials such as wood, plasterboard, ceramics, etc., can also be used. These two faces (1) are parallel to each other. Their fixation is carried out by two outer metal stringers (2a) on the sides and two connecting ends (5) on the top and bottom ends.
  • the panels comprise at least one connecting end (5), on which at least one wedge is located (7).
  • at least one wedge (7) it means that it is a capping panel for façade fixing (PRF) and aimed at being vertically positioned.
  • PRF façade fixing
  • All these elements are welded together and form the metal structure of the panel.
  • the components of the aforementioned metal structure are preferably galvanised steel.
  • the panels comprise fastening elements (4), which promote the fitting between panels, either along the outer stringers (2a) or at their connecting ends (5), through the wedges (7).
  • These fastening elements (4) can be located between the wedges (7) and/or at the ends of the wedges (7), but also along the outer stringers (2a); if they are located along the outer stringers (2a), then it is a capping panel for façade fixing (PRF) aimed at being horizontally positioned.
  • PRF façade fixing
  • the outer stringers (2a) comprise on their outer faces a recess (10), or an indentation, for placing the sealant.
  • the purpose of this sealant is to ensure a thermal, acoustic and hydraulic insulation between panels.
  • the panels may have inside, between the two outer stringers (2a), some inner stringers (2b).
  • inner stringers (2b) are aimed at increasing the panels' resistance, so they may or may not have this component, and if they do, they can have a number of inner stringers which is suitable for the length of the panel.
  • These stringers will be used and sized according to the gaps to be bridged, especially in slab panels.
  • the inner stringers (2b) can preferably be trusses, as illustrated in the Figures, or they can have another configuration (not illustrated).
  • the panels comprise infrastructure pipes (6), in the amount of at least one, but they can comprise a plurality thereof, depending on the building's needs (plumbing, telecommunications, electricity, domotics).
  • These pipes (6) are attached to the metallic structure and bores are made in the stringers, and are located between the outer stringers (2a) and the faces (1).
  • filler (3) low density material
  • the filler (3) is preferably non-petroleum-based polyurethane foam. It should be added that, this type of filler, besides having a high thermal and acoustic performance, does not contain volatile organic compounds, nor does it contribute to global warming and ozone layer's depletion.
  • the panels In this perspective of promoting high thermal and acoustic insulation performance, combined with greater strength and stability of the built structure, the panels have, in a preferred configuration, a thickness of at least 15 cm. These numbers are higher than those used in the state of the art, and there is an optimisation of stability as from 15 cm of thickness, and in an even more preferred embodiment, with 20 cm of thickness, their performance in terms of insulation and structure is also more significant.
  • the panels are fixed to each other by means of parts designated as fastening elements (4), located either between the wedges (7) and/or at the ends of the wedges (7) at the connecting ends (5), but also along the outer stringers (2a), and are attached to these elements by welding.
  • Each panel can have a variety of fastening elements (4), which must be located in at least one outer stringer (2a) or one connecting end (5).
  • the panels can also comprise in one of the connecting ends (5) an inverted wedge (9) to be fitted into the wedges (7), these panels being the ones to be used in the facades, the so-called façade panels (PF).
  • an inverted wedge (9) to be fitted into the wedges (7), these panels being the ones to be used in the facades, the so-called façade panels (PF).
  • the panels comprise two fastening elements (4) in at least one connecting end (5) and located in the outer ends of at least one wedge (7), and an inverted wedge (9) in the other connecting end (5); these will be the capping panels for façade fixing (PRF) to be vertically positioned and whose width must be at least equal to half the width of the panels (P).
  • PRF façade fixing
  • the panel (P) has at least three fastening elements (4) in at least one connecting end (5) and two fastening elements (4) located in the two outer ends of the two wedges (7) and a third fastening element (4) between the two wedges (7).
  • the panel (P) comprises at least one fastening element (4) located in at least one outer stringer (2a); these will be the capping panels for façade fixing (PRF) and aimed at being horizontally positioned.
  • the fastening elements (4) are located at a distance of 60 cm between them.
  • the fastening elements (4) have at least two holes to receive at least two fixing screws (8).
  • These fastening elements (4) are the elements that allow the panels to be joined together, and this fitting between panels can be performed either horizontally or vertically.
  • the fastening elements (4), located in the connecting ends (5) must be positioned in such a way that the screws (8) of each fastening element (4) have a rotation of 90° relative to the fixing screws (8) of the fastening elements which are respectively the subsequent and the preceding one, in case they are located in the connecting ends (5).
  • each typology of each panel implies that its placement is sequential, so that all the panels are fixed, these being shiftedly placed with respect to each other, i.e., with the outer stringers (2a) of the vertical and horizontal panels, in all their preferred embodiments, being positioned discontinuously, there being no room for fragilities in the buildings, but also allowing their subsequent reorganization or reconfiguration and expansion.
