DEVICE FOR FIXING THIN ELEMENTS TO FACADES

Abstract

 A device for fastening elements of small thickness on facades, particularly modular elements of porcelain material or other materials of small thickness on ventilated facades, for which it uses suspension profiles designed to be fastened to the porcelain elements or other materials. It is characterised because the suspension profiles include a tongue that is shaped and sized so that it allows the coupling thereof to the horizontal support profile fastened to the vertical surface on which it is installed.

Description

Subject of the Invention

[0001] This invention refers to a device for fastening elements of small thickness on facades. It provides essentially novel features and notable advantages with respect to the known means that are used for the same purposes in the current state of the art.

[0002] More particularly, the invention proposes the development of a device that is especially indicated for fastening modular elements of porcelain material or other materials of small thickness to be used on ventilated facades, which is applicable to both newly constructed facades and the renovation of already existing facades.

[0003] The field of application of the invention is obviously included in the industrial construction sector in general and in the construction of ventilated facades in particular.

Background and Summary of the Invention

[0004] In the current state of the art, embodiments of systems are known that are designed for fastening porcelain elements or other materials of small thickness used to line facades in order to form what are called ventilated facades, in which said modular lining elements are positioned a certain distance from the interior or original facade. These devices can be mechanical, they can use chemical,adhesives or they can use a combination of the two, such that the piece remains fastened to the support elements or substructure in order to form the ventilated facade.

[0005] In general, the embodiments of devices for fastening modular elements for constructing ventilated facades known by the inventor have numerous disadvantages, all of which are derived from the difficulty of reliably fastening an element of small thickness. This is especially the case with mixed and mechanical fastenings and fastenings that use adhesive in which prior machining of the pieces is required, with the ensuing difficulty that this involves, especially when it concerns elements that have to be adapted on site.

[0006] The device fastening for modular elements on ventilated facades, object of the invention, consists of a profile with a sufficiently wide surface so that it assures perfect adherence, and a tongue (at the bottom or top part, depending on the position of the piece) that extends along its entire length ands acts as support along the entire length of the base of the piece, thereby preventing it from falling due to gravity. This is a mechanical fastening, and it thus prevents glues from having to work continuously under shear stress, which would cause a reduction of the strength of the adhesive material. In this form of embodiment, glue only has to support suction loads, which are sporadic and for which adhesive glue is more than sufficient.

[0007] The device of the invention for fastening porcelain elements or other materials is furthermore characterised because each element has been designed with extensions in the gluing zone, which assure that at the moment they come into contact with a ceramic element or other materials to which they are joined, the amount or dose of glue will be correct, given that even though a decision may be adopted to increase the pressure on the profile, the shapes of the ends will prevent the elimination of more glue than what is necessary, thereby maintaining the precise amount.

Description of the Preferred Embodiment

[0009] The device for fastening porcelain elements or other elements on ventilated facades, object of the invention, which is described below as an example of the embodiment, includes the suspension profiles (1) and (2) that are joined to the porcelain pieces (6) or other materials of small thickness using the support flange (3) as support for the permanent gravity loads of the pieces (6), suspended from the profiles (7) using a hook (5), and the guide flange (4), which also incorporates glue in the section (9) that joins the profile (2) to the piece (6), thereby preventing the piece from falling due to the suction effect on the facade.

[0010] The proportionality and the shape of the fastening profiles can be appreciated in Figure 1, which highlights the flanges (3) and (4) and the hooks (5), which are the elements that characterise the invention.

[0011] The coupled elements as a whole and the way in which they are interrelated can be appreciated in Figure 2, whereby the top piece (6) is joined to the part (1) by means of the glue deposited in the zone (10) and the bottom part of the previous piece (6) is joined to the part (2) by means of the glue deposited in the zone (9). In turn, pieces (1) and (2) are suspended from the horizontal profile (7), which is joined to the vertical surfaces by screws (8).

[0012] An end view of the rear part of profiles (1) and (2) can be appreciated in Figure 3, including the contact striations formed by zones (9) and (10) for applying the glue in contact with the modular porcelain elements (6). It highlights the suspension hooks (5) anchored on the tongues of the profile (2). In this embodiment, the profiles to be joined to porcelain pieces (6) or other materials are referenced as (1bis) and (2bis), and they have respective tabs (11) formed on the support flanges (3) and (4), which are projected orthogonally with respect to said holders, on a parallel plane with the body of the profile itself and at a predetermined distance from the latter. These tabs can be introduced in the interior of complementary grooves made on the longitudinal edges of the porcelain elements (6), thereby providing highly effective and increased retention of the pieces in their effective position.

[0013] Finally, Figure 4 constitutes a perspective illustration of a practical implementation of the suspension profiles (1) and (2), in which the characteristic construction details of said profiles can be appreciated, and they appear in opposing and parallel positions, separated from each other in a situation equivalent to the schematic representation of Figure 1.

Claims

1. A device for fastening elements of small thickness on facades, particularly modular elements of porcelain material or other materials of small thickness on ventilated facades. It includes suspension profiles (1, 2) designed to be fastened to the porcelain elements (6) or other materials.
