Description

CONSTRUCTION SYSTEM FOR FACADE VENTILATED WALL

Field of the invention The invention falls within the Industrial Design and in the technical field of construction and more specifically in the solutions for facade enclosures.

Background of the invention

Traditional ventilated facade enclosures present a series of problems such as: Complex metal structures that support the cladding pieces joined together by screws and fixed to the enclosure wall by metal or plastic anchors. Thus, these traditional ventilated facades require very specialized assemblers. The need to mount the aforementioned metal structures on a wall with sufficient bearing quality, and which, not being controlled by the manufacturers of the ventilated facades, may not have the necessary resistance over time to support the entire structure-clad assembly . Deterioration of fasteners, hardware and other metallic elements with the passage of time, because they are subject to aggressive atmospheres that may occur in cities, coastal areas or extreme climates. Long runtime of traditional ventilated facades. High Cost of the wall + metal structure + cladding or cladding assembly.

Description of the invention

The invention presents a ventilated wall system for facades, comprising an interior wall formed by pieces that have a rectangular prism shape, which have a plurality of supports of the same material on the outer face of the inner wall. A plurality of clad view pieces are embedded on the inner wall by means of crimps that the clad view pieces have on their inner face, and fit perfectly with the inner wall brackets, allowing air to pass through the space between the interior wall and the pieces of cladding, thus achieving the effect of ventilation and constituting a ventilated wall for facades.

To solve the aforementioned problems presented by the current ventilated facades, this new invention is presented. It is a very simple solution, and

It is based on making the wall of the enclosure with pieces that already have on its face outer some supports, that serve to crimp the pieces seen of placacado, being all of the same material and with the guarantee of durability over time. Thus, the advantages of the invention are: - Absence of metal structures, fasteners and screws;

Possibility of replacing cladding or cladding pieces with different ones formats; Fast execution:

When the outer wall of the enclosure is made, the cladding supports are already placed and aligned The cladding is very fast and the interior wall is finished once this new Wall comprises at least:

(i) A Wall Piece, which is placed directly on the structure of the building and is finished as a facade. This consists of a rectangular block of large format, with supports of the same material on its face outside the wall, where the cladding will be crimped. These supports allow a sufficient separation between the wall and the cladding, once fitted, so that the air can circulate between them. They are placed on a locked joint to give the highest shear resistance to the wall. According to other features:

2.

The wall piece may also comprise:

3.

The wall piece can also comprise alignment and clamping means selected from:

2nd)

an upper face comprising a plurality of protuberances;

2b)

a bottom face comprising a plurality of recesses;

2 C)

the protrusions and recesses being configured to conform

tongue and groove joining means between the recesses of a piece

of upper wall and the protuberances of a piece of lower wall.

3a) a groove of alignment and elevation in elevation, located on the first outer face, configured to accommodate an alignment and elevation strap in a horizontal position;

3b) a groove of alignment and clamping in plan, located in the upper face, configured to accommodate in a vertical position a strap of alignment and clamping in plan;

and combinations thereof. Alignment and clamping strips in elevation and alignment and clamping strips in plan can be metallic.

4. The grooving of alignment and clamping in plan can be located in a protuberance.

(ii) A Plating Piece, consisting of a large format platelet, with the outer face seen and presenting on the inner face some crimps, which fit perfectly into the supports of the wall pieces.

Likewise, and to solve all the encounters that exist between the wall and the structure, the following elements and pieces have been developed to make said wall:

(iii) Half Wall Piece, is a section of the wall piece 1/2 of its horizontal length.

(iv)

A Patch Piece, which consists of a block of 1/3 of the thickness of the wall piece, with identical supports on the outer face of said piece and that is used to cover the structure of the building in those areas where the piece of wall does not fit, such as slabs and pillars, and also has the wall piece grooves for proper alignment and fastening of the same through the strips.

(v)

A Coupling Piece, consisting of a 2/3 block of the thickness of the Wall Piece, which is always used in vertical or horizontal pieces, and as Trasdós of the Patching Piece in meetings with the structure.

(saw)

A Piece of Mocheta, which is a block with the exterior faces seen and that serves to return the wall in the gaps of doors and windows to the carpentry. This piece has a dovetail relief on the face in contact with the wall, to prevent the mortar from peeling off. Likewise, these pieces are linked to the wall by means of fiberglass meshes embedded in the mortar of the horizontal joint.

(vii) A Zuncho Piece, which is a "U" shaped block of the same format as the Wall Piece, and with the same surface finish on the outer face as the Clamping Piece. It is used to form the Lintel in doors and windows taking advantage of the hollow of its interior to make a loading beam with reinforced concrete.

(viii) A piece of gutter, with the same surface finish as the plating part, and used to cover the windowsill. This piece has a drip on the bottom that flies to the outside of the wall, to prevent water from flowing through the facade.

(ix) Some fasteners, such as metal strips that serve to align longitudinally and transversely the wall and patch pieces, when installed in grooves that have said parts for this purpose. They also serve as a fastener while setting the mortar for joining said pieces. And the fiberglass meshes, which are embedded in the mortar of the horizontal joint and guarantee, by its high tensile strength, the fastening of the corner pieces and the mochetas.
