Description

Waterproof tray for ventilated façade.

Background of the invention

A facade is the vertical exterior enclosure of a building that insulates and protects its interior from conditions Outdoor weather.

A ventilated facade has the characteristic main to have an air chamber between the lining last outside of it, in contact with the outside, and its thermo acoustic insulation; inside this chamber, the ascending air circulation by the chimney effect along of the entire facade and thanks to an entry of outside air at the base of the façade and an exit of it in its highest part; this allows to use the ventilation as an insulator thermal effect already known and used since ancient times in the insulation of the roofs of the buildings and that in the Currently, due to technical advances in construction, it is possible to use it on facades, both in new construction and in rehabilitation, thus contributing to energy saving and to the development of a bioclimatic architecture.

All facade systems consist of two Elements: the structural support system of the plates coating, and the plates themselves: the structural system, metallic, and in most cases it also has a first enclosure wall of the building that supports it, It consists of the following elements:

one.

Pieces or support brackets, which are pieces usually in "L" that are distributed on a regular basis in a reticle that must be perfectly rethought on the enclosure wall, and which are fixed to it by screws and tacos (mechanical or chemical).

2.

Vertical profiles, which are pieces longitudinal metal bolted to the support pieces, specially configured to receive support staples from the plates.

3.

Staples, which are metal pieces that serve as a connection between the cladding plate and the profile vertical.

In some cases, the staples are fixed to others. longitudinal profiles placed horizontally attached to the verticals; in these cases, the stakeout does not require being so exactly as in the general case, since the staples can move horizontally to the right place to crimp with the plate.

Object of the invention

The present invention relates to a system of waterproof trays for ventilated façades that serve as structural support to the facade cladding, are made of sheet metal, have a series of folds at their edges formed by folding, pressing or extruded profiling; a series of perforations allow the passage of the ascending air in the chamber that they form and others allow the water that could pass through the façade plates in case of blizzards, powder snow, etc. to be passed from one tray to the next. ; The longitudinal ribs formed by the successive fitting of the trays make them capable of supporting the thrust transmitted to the facade by the wind as a whole, as well as serving as a guide and support for the staples that support the facade plates. These trays are placed with the nerves in a horizontal position and cover the entire facade. They can be carried out in several measures depending on the size of the façade plates to place metal profiles placed vertically called uprights and supported on the structure of the building through the slabs, in this case the existence of a resistant wall is not necessary previous.

These trays configure a system that distinguishes from the ventilated facade systems described in the background on the following:

one.

Thanks to the trays fitted each other set up a waterproof surface, the insulator located behind them he is not exposed to damp and therefore does not suffer impairment in their functions; in most systems Traditional ventilated facade exposed, the insulator is directly in contact with the air chamber, and not protected sufficiently against outside damp.

2.

Do not you need a support wall for the anchoring of the structure with what the Savings in its construction is important. It allows saving in material and labor because we can replace the construction of the wall support by metal studs, with which the phases of support wall construction, anchor plate placement, upright placement and horizontal profile placement support, is reduced to the placement of uprights and placement of trays

3.

It allows labor savings of placement because the successive fitting of trays without possibility error speeds up the operation, in addition to the amounts must not be placed at its exact point as with the anchor pieces of the usual systems; rethinking the first tray, all the  facade is defined. The staking of metal studs verticals is simple, because the only plane in which you should control its flatness is that of the outer face of the profiles parallel to the facade, no matter if a crash occurs in vertical of the same, nor that the distance between them is exact.

Description of the invention

The present invention relates to a waterproof tray for ventilated façade , starting from extruded metal or metal sheet subsequently deformed at its edges by folding, profiling or pressing, configuring it in a "U" shape and placing it with its base supported by the structural elements of the facade. The U-shaped trays are arranged on the facade, with the base in an upright position and with the ribs of its wings in a horizontal or inclined position according to the configuration of its wings. Behind them, housed between the mounting elements supporting them, the insulating material is placed, any of those commonly used in construction (glass wool, rock wool, extruded, expanded polystyrene, reflective sheets, etc.)

Each nerve, configured by the union of the contiguous wings of two consecutive trays, (which may present rectangular, trapezoidal, triangular section, etc.), has a series of perforations on their upper and lower faces, to make air circulation from one tray to the next possible allowing the ventilation of the facade; said perforations are perform in the form of drawing inside out setting some air passage windows as mansards that prevent the water that could flow through the perforated wing can penetrate the inside the nerve through the sheet. The U wing of each tray that once placed on the facade is at the bottom, it is placed overlapped on the upper wing of the lower tray and has a fold at its lower end on itself outward that allows the staples to support of the façade plates rest on it, facilitating staking of the plates and avoiding leveling errors; this fold bottom has a series of perforations to prevent the Water is stored in it. The U wing of each tray that a Once placed on the facade it is on top, it has a fold that facilitates the fit of the upper tray.

The trays are placed from the bottom up, being only necessary to rethink the first tray well lower start of the facade; the others are fitting successively in the previous ones. They are usually fixed by self-drilling screws to the supporting element; however, in depending on the nature of the support, the fixation will be chosen between the usual systems used in construction.

The trays can be manufactured in so many sizes as facade plate formats exist (in vertical dimension; horizontally each tray supports all formats).

It does not alter the essence of this invention the variation of materials, shape, size, arrangement of perforations and shape thereof, the formation of the folds in the edges of the trays, whose description is made in a non- limiting, this being sufficient for reproduction by a skilled.
