Description

Insulated tray tray.

Background of the invention

In the construction of roofs of tiles for buildings with a slope greater than 15º, light metal structures composed of trusses, belts, base plates and battens on which the tiles are placed are increasingly used. This type of roof characterizes its low weight as it is constructed with lightweight materials, its speed of execution and its dry assembly. Some covers significantly simplify the system using a single element, the tray-tray , as a support for the tiles, replacing the assembly formed by straps, base plates and battens of a classic light cover.

Object of the invention

The present invention relates to an insulated tray tray that, in addition to supporting the roof tiles of a roof and replacing the assembly formed by belts, base plate and track, allows to contain inside a thermal and / or acoustic insulating element ; its special configuration also makes the roof self-ventilated and a double cover, since on the one hand and thanks to a series of perforations that the trays have, the air circulates freely from the eave to the ridge between the lower plane of the tiles and the top of the insulator; another series of perforations make it possible for the filtered water to the trays due to the eventual tearing of tiles, to run over the insulating plate to the eave. The rastrel trays also have on their wings a series of lace folds for the union of two consecutive rastrel trays that allow a simple way to cover the entire skirt.

Description of the invention

The present invention for which it is requested to be registered as a Utility Model, refers to an insulated trailing tray that, by successive union with others equal to it by fitting and fixed to the roof support structure (trusses, beams or boards ) by means of nails, thymes or other system of the usual ones in construction, it forms the base plate on which the roof tiles of a cover rest and allows to lodge in its interior a thermal and / or acoustic insulating material. Constructed in profiled or folded metal sheet or in extruded metal, it has a U-shape and is placed with the base resting on the support structure of the roof with the profile ribs perpendicular to the maximum slope line of the roof; it presents longitudinally, in the two wings of the U perpendicular to the support plane, a series of folds that form polygonal sections that constitute the resistant ribs of the support base plate of the tiles when a tray with the following one overlaps; Thanks to these nerves, important lights can be saved between supports, the nerves also serving as support rails for the tiles corresponding to each course. The distance between the ribs thus constituted by the overlapping of adjacent trays will be equal or submultiple of the distance between heels of two rows of consecutive tiles. The system adapts to all tiles on the market.

In each tray with insulating tray , we can distinguish two zones: a lower one, which serves as a housing for the insulator and has the same thickness as this one, characterized in that the wings that start from the base and between which the insulator is housed are perpendicular to said base, the walls of the wings of two adjacent trays that form each rib being attached without leaving any intermediate space, so that the insulator housed in a tray is separated from the insulator containing the next one only by the thickness of the two metal sheets ; these sections of the base of the attached nerves may have a straight or broken section; the other zone, the upper one, begins in the plane parallel to the support base of the trawling tray at the height of the coronation of the insulator, and in it the ribs of the profiling are separated and overlapped and have two series of perforations, the first of which allows the autoventilation of the area of the undercover located between the tiles and the insulator, and the other the elimination of the water that by breakage of tiles, wind, snow, etc., penetrates under them. Both the perforations for ventilation and those provided for the elimination of filtered water are found in the two wings of the adjacent trays that join to form each rib, and are separated from each other and in two parallel planes. The highest part of the wings of each tray have fins that allow the fitting of a tray with the next and the support of the tiles on them.

The insulator that is placed inside each tray can be of different types: on plate, panel or blanket (polystyrene, glass wool, rock wool, vegetable fibers, animals, etc.,) or projected (polyurethanes, rock wool, etc.,). In all cases, for the type of tray described so far, the upper face of the insulator should be waterproof, either by the placement of attached sheets on said aluminum face or asphalt, or because it is the insulating material itself; in this last case the tightness between the insulator and the walls of the profiled ribs and tray base that contain it should be total to prevent the passage of water to the base of each tray; in the case that it was not so or that the insulating plate did not carry superior waterproof protection and let the water pass to the tray base, an evacuation system must be available in the support base of the tray by means of folds and perforations Complementary as explained below in Figure 8.

To prevent water that due to possible breakage of tiles penetrate the insulator it has been arranged that each nerve configured by the union of the wings of two consecutive trays is configured in such a way that the insulator located in the bottom tray (which incorporates a waterproof type sheet foil, asphalt, etc., or is waterproof), stay lodged and protected from water that can descend from the upper tray under a crease of the profiling; it is also provided that the sheet waterproof aluminum or asphalt that protects the insulating plate located in the upper tray cover the profiled fold arranged in the upper part of the nerve; in this way, combining the disposition of the waterproof insulation sheet and the configuration of the profiled folds on both sides of each nerve, along with the series of perforations in them, we get the water to pass successively from a tray to the immediate lower until reaching the eaves.

The base plate formed by the successive lace of insulated trays can also serve as a support for other types of roof covering, such as slate, panels or sheet metal (tapped, zinc, copper, etc.).

It does not alter the essence of this invention the variation of materials, shape, size, arrangement of perforations and shape thereof, whose description is made of non-limiting form, this being sufficient for reproduction by an expert in the field.

Brief description of the drawings

Figure 1.- It shows a cross section of an insulated trailing tray (1) without the insulating plate and its form of connection with the adjacent ones, in which the fit between them can be seen through the union of its wings, on the cover slope. A series of transverse perforations (2) allow the passage of air from one tray to another. In the edges that form the indicated folds there are also a series of perforations (3) through which the water filtered by the eventual breakage of tiles passes from one tray to the next until it reaches the eaves.

Figure 2.- Shows the same previous section in which has been introduced insulating material (4). As you can see, the insulator is coated superiorly with a membrane waterproof (5) and is housed under the fold of the upper nerve of the tray; in the lower nerve of the tray, the membrane waterproof lining insulation covers the metal crease intended to prevent water from entering the insulator continuing to the next tray. In the drawing you can follow  perfectly the path that the water eventually filtered by the Tile breakage performs to move from one tray to the next without penetrating the insulator.

Figure 3.- Shows a perspective of a tray insulate without insulating plate, with wings profiled at the top, with its lace fins corresponding to form the resistant nerves, in which appreciate the area of horizontal perforations (2) for allow the passage of air between trays in the space included between the tiles and the insulating plate. You also appreciate the zone (3) of perforations in the edge of the folds for allow the passage of water from trays to track the following.

Figure 4.- Shows a perspective of two insulated tray trays, without the insulating plate, on which the form of union of a tray with the following one is appreciated, with its corresponding lace folds in which the area is appreciated of horizontal perforations (2) to allow the passage of air between trays. The area (3) of perforations in the edge of the folds to allow the passage of water from some trays trace to the following.

Figure 5.- Shows a perspective of a tray track with complete isolation, in which the insulating plate, with profiled wings on top, with their corresponding lace fins to form the nerves resistant, in which the area of perforations is appreciated horizontal (2) to allow the passage of air between trays in the space between the tiles and the insulating plate and the perforation zone (3) at the base of certain folds for allow the passage of water from trays to track the following. The insulator (4) has a waterproof membrane on top (5).

Figure 6.- Shows a perspective of two insulated rastrel trays, with insulating plates already placed (4), which shows that the insulating plate is lodged under the fold of the upper nerve in the upper part of the tray; the impermeable sheet (5) overlaps the nerve fold bottom allowing water to flow from a tray to the next without penetrating the insulator.

Figure 7.- A partial section of the skirt of the cover, where you can see several trays with insulation and the way of placing the tiles (6), supported with his heels on the nerves of the profiling. They are also appreciated the screws (7) fixing the trays on the structure cover support, which is one of the possible ways clamping provided.

Figure 8.- This figure represents the section of an insulated tracking tray in which it does not have Waterproof upper membrane and is not moisture absorbent. In In this case, the water that breaks through the insulator crosses this by its edges to the base of the tray, in which they have provided a series of perforations (3), a heel (8) to prevent that the water penetrates inside the cover, and a nerve additional optional (9) for, in conjunction with the power heel Hang items without drilling the tray. In this way, the water move from one tray to the next to the eave at the level of the tray support base.

Preferred Embodiment of the Invention

The first track that is placed for covering of a roof skirt, is the so-called eave profile, which It is the profile on which the tile course that flies rests on the eaves After the eave profile, and depending on the dimension of the flight of the tiles of the first course on said profile, the first tray tray is placed with insulation so  the heel of these tiles rest on the lower wing resistant of said tray. The trays are attached to the structure support by nails, self-drilling thymes, etc. Restraint from the tiles to the tray can be made using screws, Special hooks or sealants. They are then placed by successively fit the following trays on which they will rest the successive rows of tiles; each course of tiles will save one or several trays to rest on the nerve of which it corresponds in function of its dimension; for this the appropriate tray will be manufactured for each type of tile. The union of the insulation plates they must be made by self-adhesive waterproof tape on the areas of union of several trays, to guarantee the total impermeability of the skirt.

Once the tiles are placed on the trays simple track of the skirt, from the bottom up, proceed to the placement of the last row of tiles, which generally it will force to cut them, measuring well the distance of cut so that the support of the sectioned section on the ridge profile, is as close to the vertical wall of the profile; be you can use a sealing material in the meeting between tile sectioning and ridge profile to avoid any type of filtration.

Finally the ridge tiles will be placed screwing them over the horizontal high part of the profile of ventilated ridge, which will be the finished cover.

Profiling supports large dimensions lengths of insulated trays, only limited by transport requirements, being able to reach 12 m and in some cases greater dimension.
