Description

OBJECT OF THE INVENTION

The invention, as exposed on the wording of the present specification, relates to an insulating support base for ceramic roof tiles which imparts to the function it is intended to, advantages and characteristics, which will be described in detail below and which mean a remarkable improvement of the current state of the art.
More particularly, the object of the invention focuses on a base for fixing curved ceramic roof tiles, of which are used in roofs and rooftops, base which, in addition to light support for the roof tiles and the same time acts as an insulating for the roof, for which it comprises, essentially, a core of insulating material coated of pre-lacquered plate and presents a rectangular modular configuration with the undulating upper surface for incorporating the roof tiles and means for easy coupling, both laterally and on its upper and lower ends, by which it is cut to the desired length, so as to cover the whole rooftop surface allowing to take advantage of any remaining piece.

APPLICATION FIELD OF THE INVENTION

The application field of the present invention is framed within the field of industry dedicated to construction, focusing particularly on the field of support systems for fixing curved ceramic roof tiles in rooftops and roofs.

BACKGROUND OF THE INVENTION

Referring to the current state of the art, it is worthwhile pointing that, although it is known the existence in the market of various solutions in the form of support bases for the roof tiles of the kind herein concerned, at least on the applicant's part, it is unknown the existence of no one presenting technical, structural and configuration characteristics similar to the ones presented by the insulating support base for ceramic roof tiles herein proposed, as it is claimed.
In that regard, it is noteworthy that in the market are known sandwich-type panels for fixing tiles, which couple to a polyurethane layer which remains in the centre, on its lower part, a wooden plank of type MDF (Medium Density Fibreboard), and on the upper part an asbestos sheet, being these limited to a maximum long of 3 metres, chose main drawback is that they have a very higher weight and forcing to place the supports of metal or concrete purling always at a distance lower than themselves so that they support one on another
There are too other insulating panels with a polyester upper layer which is painted mimicking the clay or garnet-coloured roof tile, and that, in this case, presents the drawback of, over the course of a pair of seasons, the colour deteriorates forcing to the subsequent repainting maintenance in the roofs.
It is then the object of the present invention to provide the market a more practical solution effective as a support for the roof tiles and insulating for the roof that avoids the drawbacks of current systems.

EXPLANATION OF THE INVENTION

Thus, the insulating support base for ceramic roof tiles proposed by the invention is configured as a novelty within its application field, as, according to its implementation and unequivocally the objects previously pointed are achieved, being the distinctive characterizing details which make it possible and which differentiate it suitably enclosed in the final claims accompanying the present specification thereof.
Specifically, what the invention proposes, as it is pointed previously, is a base deigned for serving as a support for fixing curved ceramic roof tiles, of which are alternately arranged on one side and the other forming parallel grooved rows determining an undulating surface in roofs and rooftops, base which differentiates in that, in addition of being a light but resistant support element for fixing the tiles, at the same time acts as a perfect insulating for the roof as it has, essentially, an insulating material core coated of pre-lacquered plate provided with heat-break points, presenting, as well, a rectangular modular configuration for easy coupling, both laterally and by its upper and lower ends, by which it is cut to the desired length, so as to cover the whole surface of the rooftop.
To do this, and more specifically, the support base of the invention is configured from a modular body of rectangular floor-plan, with fixed width, preferably one metre, and variable long, according to the needs of each case, as well as with limited thick and undulating upper surface, based on the dimensions of the roof tiles, being said body formed by, at least, a core of insulating material which is covered, on all its faces, by pre-lacquered plate.
The insulating material of the core, preferably, will be chosen from polyurethane, rock wool, cellulose or polystyrene balls.
In the undulating upper surface of the modular body, which is fully smooth with the mentioned pre-lacquered plate, are incorporated the curved ceramic roof tiles, which are firmly joined in their entire surface by exerting some pressure thereon, being fixed to said surface by means of epoxy glues so that they don't allow neither longitudinal nor lateral movement. Additionally, it is contemplated the incorporation of non-slip hooks to be placed between the tiles, if so preferred, to ensure their fixation.
On the other hand, to achieve the necessary union and consistency inside of the modular body of the base, it is provided the existence of a number of flat bars and profiles of rolled galvanized steel which are joined with rubber joints, which determinates a heat-break point.
More specifically, in the insulating core and coinciding with the valley areas of the undulating surface, are provided, at least, longitudinally flat bars arranged by vertical pairs separated in their centre by a heat-break rubber joint.
And, preferably, furthermore, also interleaved in the insulating material core, are provided longitudinal reinforcement profiles which, incorporated in a preferred mode along and coinciding with the centre of the peak areas of the undulating surface, impart stiffness to the base, especially in case of need of supports when it has long dimensions, being calculated in amount and thickness according to the characteristics to be covered in each case. Furthermore, at least the upper edge of these profiles incorporates also rubber joints as a heat-break point among them and the pre-lacquered plate of the undulating upper surface.
On the lower part, the modular body forming the support base of the invention can be, either fully smooth and flat, with the pre-lacquered plate of any desired colour, as the customer demands, and, optionally, provided of holes for screwing de wooden strips so as to place false ceiling of frieze or other decorative elements.
In any case, the modular body has, on its respective lateral edges, quick-fitting means for the lateral coupling of bases adjacent to one side and another, consisting said fitting means of an angled longitudinal mortising, of about more or less 30°, provided along one of the sides of the base, and a longitudinal projection of complementary angle which, provided along the opposed side, fits in the aforementioned mortising of the contiguous plate, preventing any lateral movement between them.
And in the heads, that is, in the upper and lower ends of the modular body of the base, when it is necessary longitudinally join more than one of them, the core is cut to a price of 10-15 cm and the pre-lacquered plate is cut only in one of its upper or lower faces or surfaces, letting the pre-lacquered plate of the opposed face projecting a portion equal to the cut stretch, which permits overlapping said protruding sheet stretch over the core of the adjacent base to be joined. This permits the cutting of the support bases to any size and taking advantage and reusing any remaining piece.
Finally, it is noteworthy that the support over concrete or metal purling will be separated depending on the angle of descent of the rooftop and always with the need for resistance and calculation of the same.
The described insulating support base for ceramic roof tiles represents an innovative structure with structural and constitutive characteristics unknown so far to this end, reasons which in combination with its practical utility, provide it with enough basis to obtain the exclusivity privilege which is applied for.
