Definitions

• Anchoring element for the linking of stanchion structures
• the invention in question concerns an anchoring element for the linking of stanchion structures, adapted for the building of load bearing substructures for supporting the facework of building facades, in particular for supporting facade facework commonly known as "ventilated walls” positioned to allow the circulation of air on the interior of the cavity wall obtained between said external facework and wall structures that are to be covered.
• the load bearing substructures currently in use are generally made up of metallic structural shapes anchored to the surfaces of the wall structures to be covered; on these load bearing substructures the wall tiles are to be put.
• the installation of the substructures includes the anchoring to the walls to be covered of perpendicularly aligned lead stanchions on which horizontal stringers or directly wall tiles are to be put; the distance between said stanchions and/or between said stringers is predetermined in relation to the type of facework provided.
• anchoring elements are used to secure the parts together; among those most commonly used are metallic rivets that are inserted into through-holes, of which some are elliptic and/or elongated, implemented in the intersecting and superimposing points of the structures to be connected.
• screws and/or bolts may also be used, but the drawbacks are substantially the same as those indicated previously; however, exacerbated by the need for more installation time.
• Anchoring element means are made up by pairs of very narrow "U"- shaped elastic pin elements of variable width and length, that are orthogonally combined, one inside the other, in order to grip the respective profiles, encapsulating them. The application is carried out on each of the four corners originating from the orthogonal superposition of the stringer profiles and stanchion profiles, in the intersecting points of the structure composed. Anchoring elements obtained in this way, also demonstrate a better absorption level of the structural thermal expansions and more moderate installation costs, however they present the drawback of having a limited resistance capacity and of being difficult to dismantle once placed in position.
• the present invention proposes an undercut anchoring element, for the linking of stanchion structures, intended for the construction of support substructures for the facework facades of buildings with or without ventilated walls, in order to obviate the aforementioned drawbacks; that is simple to construct, is easy, safe and quick to apply, that allows fast and economic correction interventions to remedy possible errors and/or assembly mismatch, that is also resistant to notable loads, that guarantees an excellent absorption level of structural thermal expansions, that is reliable over time, that permits both the anchoring of the stringers to the stanchion as well as the anchoring and the dismantling of facework directly connected to the stanchion and that it is economical both from the constructive as well as applicative point of view.
• Figure 1 shows a first example of an anchoring element, made up of a leaf spring elastic tie plate with a folded base equipped with lateral extensions and external notches, in side, front and perspective view,
• Figures 2a and 2b show an anchoring element of the type in Figure 1, during the phase of inclined insertion and in a straight orthogonal position, on the anterior flanges of a stanchion,
• Figure 3 shows in perspective the anchoring element according to Figure 1 and 2, in practice, that connects to a stanchion and supports a stringer
• Figure 4 shows in perspective a pair of undercut anchoring elements according to Figures 1, 2 and 3, opposed and connected to a stanchion, that support a stringer,
• Figure 5 shows a second example of an anchoring element, made up of a leaf spring elastic tie plate with folded base equipped with lateral extensions and internal notches, that is to be connected to a second type of stanchion and supports a stringer,
• Figures 6a and 6b represent certain anchoring element typology according to the invention, equipped with further additional elastic hooks and/or notches, to directly support the wall tiles, and Figures from 7a to 7i show other possible undercut anchoring element configurations, according to invention.
• the anchoring element is substantially made up of a leaf spring elastic tie plate 1, with substantially vertical expansion and eventually shaped, connected to a transverse base 2 folded in various ways, at the opposite and lateral ends of which hooking slots and/or eyelets (4, 4', 17) are present.
• a first solution ( Figure 1), the shaped leaf spring elastic tie plate 1 with vertical expansion is connected to a transverse base 2, square folded, whose opposite ends protrude laterally with extensions 3 on which the hooking slots are made up of longitudinal notches 4, open and directed towards the exterior.
• the anchoring element formed in this way is designed to be applied on the vertical stanchions 5 of the substructures that support the facework of building facades, with or without ventilation.
• Said stanchions 5 are generally box-type metallic structural shapes with front opening 6, equipped with flanges 7 ( Figure 2).
• the anchoring element can be applied to the stanchions 5 in the following way: its transverse base 2 is introduced into the front aperture 6 of the stanchions 5, orienting it with an incline in order to place the posterior teeth 8 of the longitudinal notches 4 over the flanges 7 of the structural itself.
• the anchoring element is rotated in the direction of the arrow 9 ( Figures 2a and 2b), positioning the base 2 orthogonally to the stanchion 5 and hooks for inserting the flanges 7 of the stanchions in the notches 4.
• the released small plate 1 tends to return elastically to its first position, resting on the external surface 13 of the stringer 12, pushing on it with the pressure corresponding to the remainder of its springback effect, impeded by the presence of the stringer itself.
• the internal edges 14 of the notches 4 are gripped and hooked against the internal and external surface of the lateral flanges 7 of the stanchion 5, operating as opposing levers with adequately elevated loads to impede any type of movement and/or sliding of the undercut anchoring element, leaving the stringers free to move as much as necessary to absorb the structure's thermal expansions.
• FIG. 6a an application example is represented that uses stringers 12 of reduced length, opportunely shaped in such a way as to support the upper wall tiles 27, while the shaped leaf spring elastic tie plate 1, with the prolongation 30 of the base 2, connects the lower wall tiles 28 to the notch 23.
• the vertical stanchions 5, according to the implementation of facework without air circulation, can be integrated into the masonry 25, or, for the implementation of facework with air circulation, the stanchions can be applied externally to the masonry, forming with their thickness the cavity wall necessary for ventilation.
• Anchoring elements are preferably made of stainless steel and/or aluminium, in combination with the stanchions and the stringers to be connected, since said materials are most valid for assuring the long duration of the structures and a corresponding resistance and hooking stability between the parts also in the presence of heavy loads; furthermore, they allow an optimum absorption level of the structural thermal expansions.
