VENTILATED FACADE

Field of the Invention

The present invention relates to elements and materials for coating 5 construction structures. More specifically, the invention relates to a set of elements for obtaining a ventilated facade with flame retardant properties.

State of the art

Ventilated facades have been used for several years. This type of facade 10 comprises: an inner sheet, which corresponds to the exterior wall of the building provided with the ventilated facade; -a non-watertight outer sheet, usually formed by pieces in the form of a plate that make up the facade or face of the building provided with the ventilated façade; and 15 -a insulating layer, formed by a chamber between the inner sheet and the outer sheet.

Ventilated facades generally allow high quality, durable finishes, also offering good thermal performance. The plates that can form the outer sheet can be stone, ceramic or any other appropriate material

20 for the closing of the building.

The existence of joints between the facade pieces that form the outer sheet avoids the typical problems of expansion, so they are facades that have a good appearance for a long time. The outer sheet also dampens temperature changes both in the thermal insulation and in the waterproofing, prolonging the life of the thermal insulation and the waterproofing. Finally, the existence of the outer sheet helps reduce the thermal losses of the building: in the summer months, the outer sheet is heated creating a convective effect that circulates the air inside the chamber. This "chimney effect" dislodges hot air and renews it with colder air. In the months of

30 winter, the air in the chamber is heated, but not enough to create the same effect and the heat is better conserved by keeping the chamber in hot air.

Within the technical field related to the cladding of constructive structures by means of the ventilated facade system, the vast majority of the plates used for cladding facades do not prevent the spread of fire. This means an increase

of risk for the users of buildings provided with these cladding means, and for the general structure to be coated, when their combustion occurs.

Plates used in the ventilated facade system with features are known

5 flame retardants These plates generally comprise a stony or ceramic layer coated on its back face, the unseen face, by flame retardant material. The main problem of these plates is that they must be machined in the workshop to be installed on the ventilated facades. The rear face of the plates is the opposite of the outer face, that is, the rear face is the one facing the inner sheet, while the outer face is the face seen

10 of the facade.

Fire retardant facade systems are also known as the External Thermal Insulation System (SATE). By means of this system, the insulating panels are fixed with adhesive mortar or similar to the exterior wall of the building, applying the adhesive mortar or similar 15 directly on the insulating panels and the insulating panels are placed on the facade forming ascending rows from the starting profile, checking the flatness of the courses. To reinforce the union of the insulating panels to the exterior wall of the building, the insulating panels are additionally fixed with mechanical anchors. Subsequently, a mesh is placed from the top of the building to the bottom, fixing the mesh to the

20 insulating panels by means of a layer of adhesive mortar. The surface formed by the mesh and the smooth and uniform adhesive mortar is left for the application of the decorative plaster.

As can be seen, although these systems provide thermal protection, they are laboriously executed, which has a very negative impact on the economic aspect.

Description of the invention

The present invention proposes a solution to the aforementioned technical problem, through a ventilated façade that maintains high thermal and acoustic insulation capabilities, in addition to flame retardant properties.

30 The proposed ventilated facade cladding system is intended for exterior cladding of facades by means of hidden mechanical fasteners connected to a metal substructure. A basic embodiment of the invention is defined in the claim.

1. The dependent claims define additional features of the invention.

Detailed description of the invention

Once the exterior wall of the building has been executed, which corresponds to the inner leaf of the ventilated façade, the brackets (2) or support brackets are placed on the exterior wall by means of the appropriate anchors. The anchors of

20 the brackets to the exterior wall of the building depend on the material of the wall and the efforts to be transmitted to it. Next, the auxiliary profiles (4) are fixed to the brackets (2) by mechanical anchors. If the facade is vertical, the verticality of the auxiliary profiles (4) can be ensured with a plumb line.

25 For fixing the insulating plates (5) directly on the exterior wall of the building (6) on which the brackets (2) are anchored, an adhesive material (50) is preferably used, this adhesive material (50) being, more preferably, a fire retardant cement base adhesive. The insulating plates (5) are provided with one or several mushrooms or cavities (51) necessary to come into direct contact with the outer wall of the

30 building (6) saving the space occupied by the brackets (2). Finally, an additional fixation of the insulating plates (5) to the exterior wall of the building (6) can be carried out by means of a mechanical anchor (52), without the need to place a mesh from the top of the building to the bottom on the insulating plates (5), neither having to smooth the insulating plates (5), nor having to apply any mortar on the insulating plates

35 (5).

Finally, the support profiles (3) are fixed by anchoring them on the auxiliary profiles (4) and the façade plates (1) are placed on the support profiles

(3) to finish the ventilated facade.

In accordance with what has been described, a basic embodiment of the invention refers to a ventilated facade configured to cover an exterior wall of a building (6) comprising: 1a) an insulating plate (5) configured to be placed on the wall outside of

10 building (6).

According to other features of the invention, the insulating plate (5) may comprise:

2a) an adhesive material (50) configured to adhere the insulating plate (5) to the exterior wall of the building (6). The adhesive material (50) may have a fire retardant cement base; 15 4a) a cavity (51) configured to accommodate a fastening bracket (2) of the facade

ventilated 5a) a mechanical anchor (52) configured to fix the insulating plate (5) to the exterior wall of the building (6); 6) cellular glass foam.
