Object of the Invention
[0001] The invention relates to a one-piece three-dimensional panel, preferably made from planar sheet metal by a cutting and bending process or by a molding process using any type of typical material of the art, achieving a structural grid of two, three or more parallel planes with variable geometry for its use in architecture and construction, being used both as an enclosing, protection or decoration element, and also as a substructure for securing other elements or as a structure of panels, plates or coverings.
[0002] The monobloc three-dimensional structural panel of the invention can be assembled in an independent use on any support for functions such as decoration and covering in facades, ceilings, walls or surfaces of all types; protection in handrails, balconies, ledges or the like; vertical enclosures in railings, lattices, partitions, fences or others.
[0003] The monobloc three-dimensional structural panel of the invention, in substructure use, creates a load-bearing substructure for ceiling, floor and wall applications in which cable or piping guiding and installation are needed, which cables or piping will pass through the channels created between the parallel planes, leaving an outer plane firmly fixed to the construction work support and the other plane being used as a base for the covering.
[0004] The monobloc three-dimensional structural panel of the invention can also be used as an integrated structure in sandwich panels, creating light, hollow, strong, reinforced and ventilated panels.
[0005] Another type of use for the monobloc three-dimensional structural panel of the invention is as an inner structure for forming partitions of plates placed against one another in which the cover plates are placed on both faces of the panel, using the channels thereof for electrical installations in addition to creating strong reinforced panels with a great support capacity for functional or decorative elements such as radiators, bookshelves, partitions or others which are fixed thereon.
[0006] Among the many unclassifiable applications of the monobloc three-dimensional structural panel of the invention there is that of being incorporated as a structure for organizing steel framework beds of floor slabs and other concrete slabs, combining it with other applications of the invention or not.
Background of the Invention
[0007] Currently no structural elements are known with the same features having the many applications of the object of the invention and constructed from a simple die-cut metal plate and having the auto-transformation versatility in figures with a different composition enabling the versatile and varied applications which have already been explained above, the metal structures which are used for reinforcing the web of panels or other bodies are generally invariable, closed and mainly rigid structures, invariable based on welded, knotted or tied metal profile or linkage members.
Inventive Step
[0008] The advantageous purpose of the invention as can be summarized from the description in relation to the object thereof in the first paragraphs of this specification is to provide a monobloc three-dimensional structural element made essentially from a planar sheet by die-cutting, die-pressing or molding, without wasting material, without the need of welding or mechanical joints and which can be used without added elements or forming part of the panels.
Description of the Invention
[0009] The invention is consequently based on transforming a configured or unfolded planar sheet metal into two, three or more parallel planes creating a permeable, structural and strong volume, or on molding the material for obtaining a monobloc three-dimensional structural panel.
[0010] The monobloc three-dimensional structural panel object of the invention is preferably made in a single continuous manufacturing process (without excluding a discontinuous process), starting by die-cutting planar sheet metal creating a plurality of aligned and symmetrically distributed regular cuts in a conveniently reticular distribution, followed by bending or pressing, which transforms the planar body of the sheet into two parallel planes joined by the segments resulting from the uncut lines determining the space separating them by way of a cellular web. Once the two parallel planes have been created, transverse and longitudinal, horizontal and vertical channels are made in the inner space. In these conditions the panel can be curved about an axis in any of the aforementioned geometric directions, always leaving the planes parallel to one another unaltered. Another possible geometry is to bend the panel by one of its intercalated or intermediate segments of the uncut segments, forming planes broken at different angles. Another possible option of the invention is a panel with three planes parallel to one another, likewise separated by the mentioned segments determining the spacing, creating a panel with three levels with two series of vertical (longitudinal) channels in two different parallel planes, as well as two series of horizontal (transverse) channels equally forming two different parallel planes.
[0011] Another possible embodiment of the monobloc panel as a substructure according to the invention is to firmly fix an outer plane on a face which can be a slab, a ground plate or a wall and adhering on the other outer plane of the panel a covering which can be a covering for ceilings, floors or walls. Conduits or pipes, cables, piping or any other service installation means are introduced in the horizontal (longitudinal) channels.
[0012] In the particularities of the invention, an installation of the panel with structural functions is considered in which a plate is placed on each outer face and the inner horizontal (transverse) and vertical (longitudinal) channels are used for the passage of pipes or conduits and cables and any other service installation element.
[0013] An added detail of the object of the invention is that since a laminar product, more specifically simple sheet metal, is essentially the basis of the invention, the die-cutting, die-pressing, shearing treatment or the like is conveniently and preferably carried out in a continuous process which can virtually carry out the cutting or die-cutting thereof and the transformation into a panel with two or three parallel planes in two steps with subsequent treatments for transforming said panels into non-planar volumetric figures, such as the cases given as an example.

Description of a Preferred Embodiment of the Invention
[0016] The following description focuses on the corresponding illustration of the depictions of the invention, based on the following:
[0017] The monobloc three-dimensional structural panel (1) of Figure 1C is preferably made in a single continuous manufacturing process starting with die-cutting the planar sheet metal (2), Figure 1A, in a regular reticular arrangement in a transverse and longitudinal direction, creating cuts (3), Figure 1B, with a preferably broken shape, and followed by bending or pressing (Figure 1C), transforming the planar body of the sheet into two parallel planes (4) and (5) joined by segments (6) determining the space (4) separating said two planes by way of a cellular web. Once the two parallel planes (4) and (5) have been created, horizontal (transverse) (9), and vertical (longitudinal) (8) channels are formed in the inner space. As described in Figures 2.1 and 2.1A the panel can be curved about an axis, always leaving the planes (4) and (5) parallel to one another. Another possible geometry, in Figures 2.2 and 2.2A, is to bend the panel by one of its segments (10). Figures 2.3, 2.3A and 2.3B depict a panel (11) with three planes (4), (5) and (12) parallel to one another, separated by segments (6) and (13) determining the spacing, creating a three-level panel with two series of vertical (longitudinal) channels (8) and (14) in two different parallel planes as well as two series of horizontal (transverse) (9) and channels (15) equally forming two different parallel planes.
