Description:
ANCHORING DEVICE FOR VENTILATED CURTAIN WALLS

The present invention relates to an anchoring device for ventilated curtain walls.

In construction, many technological solutions are currently widely used for the thermal insulation of buildings.

One type of technological solution is constituted by what are known as ventilated facades.

Such solution identifies a system of perimeter walls that define an air gap.

Specifically, the perimeter wall in masonry is thermally and acoustically insulated using rock wool panels, which are applied on the outer side of the masonry facing and are fixed thereto with suitable inserts.

The outer finishing elements are kept spaced apart from the insulation by a system of metallic profiles and brackets, made of metal or in some cases of plastic material, which are anchored directly to the masonry facing behind.

The gap allows the passage of air, which occurs as a result of a form of stack effect.

The ventilated facade technique is very often used, specifically, in new buildings intended for tertiary and commercial use.

It is also indicated for interventions on existing buildings that are undergoing architectural restoration, while at the same time optimizing the energy performance of the building.

One drawback of the solutions currently adopted is a certain complexity in fixing the insulation to the masonry wall, since a high number of inserts need to be used, which entails the need to operate by first making a series of holes and then inserting the corresponding inserts.

The aim of the present invention is to provide an anchoring device for ventilated curtain walls that is capable of overcoming the above mentioned drawback. Within this aim, an object of the present invention is to provide an anchoring device for ventilated curtain walls that is capable of rendering the operations to anchor the layer of insulation to the wall more convenient and rapid.

Another object of the present invention is to devise an anchoring device for ventilated curtain walls that has a low production cost so as to render its use advantageous from an economic viewpoint as well.

This aim and these and other objects are achieved by an anchoring device for ventilated curtain walls according to claim 1.

Further aspects and advantages of the invention will become better apparent from the description that follows of some preferred, but not exclusive, embodiments thereof, which are illustrated by way of non- limiting example, and with reference to the accompanying drawings, in which:

Figure 1 is a perspective view of the anchoring and support bracket according to the present invention;

Figure 2 is a partially cross-sectional side view of the anchoring and support bracket;

Figure 3 is an enlarged- scale view of the coupling between the first anchoring element and the second anchoring element of the anchoring and support bracket;

Figures 4 to 7 are perspective views of the sequence of fixing and using the anchoring device according to the invention.

With reference to the figures, the present invention relates to an anchoring device for ventilated curtain walls, generally designated with the reference numeral 1.

According to the present invention, the anchoring device 1 comprises at least one anchoring and support bracket 2, which comprises a first anchoring element 20 and a second anchoring element 30.

The first anchoring element 20 is provided with a portion 21 for fixing to the outer surface 50a of a masonry facing 50 and a supporting portion 22 extending along a direction of longitudinal extension 100 substantially at right angles to the plane of arrangement of the outer surface 50a of the masonry facing 50.

For the purposes of example, the fixing portion 21 comprises a flat surface which in use is designed to arrange itself parallel to the outer surface 50a of the masonry facing 50: the flat surface is provided, advantageously, with fixing slots 21a.

The second anchoring element 30 is associatable in a locked position with the first anchoring element 20 at at least one coupling portion 22a defined on the supporting portion 22 in order to clamp at least one portion of at least one insulating panel 60 between the outer surface 50a of the masonry facing 50 and the second anchoring element 30.

With reference to the embodiment shown in the figures, the coupling portion 22a extends substantially parallel to the direction of longitudinal extension 100.

In this case, the second anchoring element 30 is selectively lockable along the coupling portion 22a.

Advantageously, the first anchoring element 20 is made of plastic so as to prevent the formation of thermal bridges.

Conveniently, the second anchoring element 30 is made of plastic. According to a preferred embodiment, the supporting portion 22 defines a connection region 22b with at least one elongated element (not shown in the figures) which is designed to support at least one external finishing panel.

Specifically, the connection region 22b is arranged opposite from the fixing portion 21 with respect to the coupling portion 22a.

The connection region 22b is conveniently constituted by a slotted region that is adapted to permit the fixing, by way of screws and bolts, of elongated elements intended to act as uprights and/or crossbeams to which to fix the external finishing panels.

The connection region 22b is arranged spaced apart, along the direction of longitudinal extension 100, from coupling portion 22a so that an air gap is created between the outward-facing surface 60a of the insulating panel 60 and the inward-facing surface of the external finishing panels.

The (or each) coupling portion 22a comprises a plurality of engagement and locking seats 25, which are arranged mutually spaced apart along the direction of longitudinal extension 100.

The engagement and locking seats 25 are, in particular, selectively engageable by at least one retention portion 31 which is defined at the second anchoring element 30.

Conveniently, the supporting portion 21 comprises a plate-like body. Conveniently, there can be a first and a second coupling portion 22a arranged at the longitudinal edges of the plate-like body that provides the supporting portion 21.

With reference to the embodiment shown in the figures, the engagement and locking seats 25 comprise, in sequence, inclined guiding portions 25a and substantially vertical retention portions 25b in order to define a sawtooth-like set of teeth which is adapted to allow the sliding of the second anchoring element 30 along the respective coupling portion 22a in the direction of approach toward the outer surface 50a of the masonry facing 50 (as indicated by the arrow in Figure 6) and the locking in place in the direction of sliding of the second anchoring element 30 along the respective coupling portion 22a in the direction of going away from the outer surface 50a of the masonry facing 50.

Advantageously, the (or each) retention portion 31 comprises a retention region 32 that can elastically yield along a direction of deformation that, during use, is substantially perpendicular to the direction of longitudinal extension 100. Conveniently, the anchoring element 30 comprises a substantially flat body 35 that defines an insertion opening 33 that, in use, can be passed through by the supporting portion 21.

In this case the retention region 32 is defined between an end portion 33a, 33b of the insertion opening 33 and a respective slit 34.

Preferably, the supporting portion 21 defines, at its free end lying opposite the fixing portion 21a, a set of teeth 26 that is adapted to facilitate passing through by the insulating panel 60 .

Use of an anchoring device for ventilated curtain walls is evident from the foregoing description.

In particular, the first anchoring elements 20 are fixed to the outer surface 50a of the masonry facing 50, by screwing for example screws into the slots 21a.

The insulating panels 60 are placed against the outer surface 50a and then the second anchoring element 30 are coupled to the first anchoring element 20 by fitting the insertion opening 33 over the supporting portion 21.

The retention regions 32 become progressively locked into the respective engagement and locking seats 25 until the second anchoring body 30 is brought to rest against the outer surface 60a of the insulating panel 60 so as to keep it in position against the masonry facing 50.

It has been found that the anchoring device according to the invention makes it possible to appreciably reduce the use of inserts for fixing the insulating panels 60.

All the characteristics of the invention, indicated above as advantageous, convenient or similar, may also be missing or be substituted by equivalent characteristics.

The invention as above is susceptible of numerous modifications and variations, within the scope of protection defined by the content of the claims. In the practical implementation of the invention the materials employed, as well as the shapes and dimensions, may be different according to requirements.
