Definitions

  • the present invention relates to a wall cladding attachment element, according to the preamble of the independent claim 1.
  • the attachment element in question is designed to be advantageously used for making claddings (for example, decorative, protective, thermal insulating, etc.) on vertical walls of buildings ("wall cladding” or “siding”), in particular for making facade claddings, both for indoor and outdoor environments.
  • claddings for example, decorative, protective, thermal insulating, etc.
  • the attachment element in question is designed to fix cladding elements (such as panels, boards, slats, strips) to a support structure of the wall so as to obtain an outer cladding of the latter.
  • cladding elements such as panels, boards, slats, strips
  • the attachment element in question relates to the field of production of fixing systems (in particular structural steelwork components) for making claddings using panels made of any material (such as wood, synthetic material, WPC, metal material, etc.).
  • the typical structure of a panel cladding comprises a load-bearing sub-structure consisting of a framework made of various materials (such as wood, metal, synthetic material) designed to be anchored to the wall to be clad.
  • a load-bearing sub-structure consisting of a framework made of various materials (such as wood, metal, synthetic material) designed to be anchored to the wall to be clad.
  • several covering panels are fixed which are arranged adjacent to each other, which form the cladding of the facade.
  • the covering panels are fixed using attachment systems which hold each panel rigidly fixed to the load-bearing sub-structure.
  • Attachment systems which provide for simply arranging the panels resting on the load-bearing sub-structure and fixing them using screws or nails which transversely pass through the panels up to being engaged in the load-bearing sub-structure.
  • the latter system of the known type can be used in limited applications (substantially solely for wooden panels) and it has the further advantage of subjecting the panels to greater stresses and having to apply - on the panels - screws or nails which remain exposed therefore deteriorating the aesthetic appearance of the cladding.
  • hooking systems - which provide for anchoring the panels to the load-bearing sub-structure using hooked plates which engage special longitudinal grooves obtained in the thickness of the flanks of the panels - have been introduced on the market.
  • a first type of these hooking systems (whose example is described in the patent EP 2278090 ) comprises several substantially C-shaped plates.
  • Each plate comprises a flat central portion, which is designed to rest against the sub-structure and on which a through hole is made, which is traversed by a screw for fixing the plate to the sub-structure.
  • each plate comprises a first and a second wing, which extend like a shelf starting from the ends of the flat central portion and from each of which there extends a retention pin designed to be engaged in the longitudinal grooves of two corresponding adjacent sides of two adjacent panels.
  • this type of fixing system (whose three examples are described in patent application n° EP 3521528 , in patent n° EP 1945881 and in patent application n° US 2014/0305064 ) comprises several attachment elements, each of which comprise a substantially flat main body.
  • the main body is provided, on the front side thereof, with a resting surface designed to receive the panel to be installed and it is designed to be fixed, on the rear side thereof, to the sub-structure through appropriate fixing means, for example screws or rivets.
  • the fixing device comprises several retention pins, which extend protruding from the resting surface of the main body, which are designed to be snap-engaged in corresponding longitudinal grooves obtained in the panel so as to fix it to the sub-structure.
  • the grooves of the panel are specifically shaped with an intermediate constriction which defines an inner undercut for engaging the retention pins.
  • the latter can be elastically deformed, so that, when they are inserted into the grooves, they can be compressed when they pass through the constriction of the groove and, upon overcoming such constriction, they widen due to elastic return being engaged in the inner undercut.
  • a first drawback of such attachment elements of the known type lies in the fact that, in case of installation of covering panels for the inner or outer wall of a building, the weight of the single panel must be fully supported by the retention pins.
  • the retention pins are made of elastic material, the latter can easily deteriorate over time, jeopardising the structural wholeness of the facade in the long term.
  • the technical problem on which the present invention is based lies in overcoming the drawbacks of the prior art known to date, by providing a wall cladding attachment element, which is capable of safely and reliably supporting the cladding elements to be fixed to the wall.
  • a further object of the present invention is to provide a wall cladding attachment element, which does not require using particular processes on the cladding elements.
  • a further object of the present invention is to provide a wall cladding attachment element, that is constructively simple and cost-effective to manufacture.
  • a further object of the present invention is to provide a wall cladding attachment element, which is adapted to the engagement with cladding elements of different types and sizes.
  • a further object of the present invention is to provide a wall cladding attachment element, which allows to easily replace each single cladding element in particular without the need to remove the cladding elements arranged adjacent to each other.
  • a further object of the present invention is to provide a wall cladding attachment element, which allows a quick and simple installation of the cladding elements.
  • the attachment element 1 in question is designed to be advantageously used for making claddings (for example, decorative, protective, thermal insulating, etc.) on vertical walls of buildings ("wall cladding” or “siding”), in particular for making facade claddings, both for indoor and outdoor environments.

  • the attachment element 1 (and in particular its first wing 21) can be directly fixed to a face of the wall 200 of the building, or, like in the example of figure 3 , it can be fixed to a support structure 201 in turn fixed to the face of the wall 200 of the building, so as to leave space, known in the technical jargon as interspace, between the face of the wall 200 and the cladding consisting of several cladding elements 100, in order to allow air to flow through between the wall 200 and the cladding to reduce the likelihood of moisture forming at the wall 200.
  • the wall 200 may be both fully solid (for example made of a masonry or wooden structure) and partially open (for example defined by a wooden or metal framework).

  • the claimed configuration of the attachment element 1 enables its second wing 22 (which protrudes like a shelf from the first wing 21) to support the weight of the cladding element 100, while the retention members 3, 4 (being compressed in the respective grooves 102, 104) develop, at least due to elastic reaction, on the relative inner surfaces 105, 106 of the cladding element 100, forces which enable to retain the cladding element 100 constrained to the attachment element 1, however without such retention members 3, 4 having to bear the entire weight of the cladding element 100.
  • the retention members 3, 4 are not subjected to strong mechanical stresses due to the weight of the cladding element 100 and, therefore, they are not easily subjected to breakage that could make the cladding element 100 of the wall 200 of the building to fall.

  • the second wing 22 bends to allow the second retention member 4 to enter into the second groove 104 of the cladding element 100.
  • the main body 2 resumes, due to elastic return, substantially the initial angle between the first wing 21 and the second wing 22, for example following the elastic return of the latter.
  • the cladding elements 100 are installed arranged one adjacent to the other along a direction transverse to their longitudinal axis L.
  • the operator may simply bend for example the second wing 22 to widen the angle between the two wings 21, 22 again and allow to remove the first and the second retention member 3, 4 respectively from the first and second groove 102, 104 of the cladding element 100, substantially by pulling the latter forward (that is moving away from the first wing 21 of the attachment element 1). In this manner, the cladding element 100 can be removed without the need to remove the adjacent cladding elements 100.
  • the installation of the cladding elements 100 is quick, given that it does not require using for example screw fixing means for such operation, significantly reducing the installation times and therefore the overall installation costs.
  • the invention thus conceived attains the pre-set objects.
