    EXPOSED COUPLING SYSTEMCoupling system with clips:carried out with xing clips connected to the load bearing structure and positioned at everyintersection of the cladding slabs, supporting the cladding slabs.

    CONCEALED COUPLINGKeil type coupling system:carried out by means of a work process on the back of the slabs consisting of a special trunca-ted-cone, non-through hole and the subsequent insertion of a special KEIL type anchoring towhich the cramps are xed that couple cladding and substructure.

    One of the main differences distinguishing ventilated faades is the type of coupling used to x the cladding (porcelaini-zed Grs slabs, full body or glaze). The coupling is known in jargon as exposed or concealed. The specic techniques areillustrated below:

    DISTANCE FOR EXPOSED COUPLING SYSTEMFor the exposed coupling system, variation is from a minimum of 110 mm to a maximum of 150 mm.

    DISTANCE FOR CONCEALED COUPLING SYSTEMFor the concealed coupling system, variation is from a minimum of 130 mm to a maximum of 160 mm.

    The structure consists of proles and brackets in extruded aluminium alloy 6063-T6 corresponding to standards UNIEN 1090 3-:2008 and DIN 18516, with a minimum thickness of 2 mm as explicitly demanded by the same standards. Thestructure is bonded to the support with special devices suitable for absorbing heat expansion/shrinking and small move-ments of the support without the cladding suffering from induced stresses.

    Safety of the whole system must be guaranteed through a case by case verication on the basis of the following regula-tions in force: EUROCODE 1 ( UNI EN 1991-1-1:2004), DIN 1055 (loads on structures); UNI 11018-2003 (design of ventilated faades); UNI EN 1090-3:2008, UNI EN 1999-1-1:2007 EUROCODE 9, (design and calculation for aluminium structures); UNI EN 1993-1-4:2007 EUROCODE 3 (calculation and testing for stainless steel structures).

    DESCRIPTION OF THE SYSTEMFixing on existing support of L-section brackets by means of plugs suitably sized and adapted to the type of support.

    Fixing of T-section proles to the brackets by means of rivets, with xed point and sliding point as per the executivedesign.Fixing of special plate in pre-painted STAINLESS steel complete with clips in STAINLESS steel AISI 316 for xing thecladding slabs.The clips may be of a colour similar to the cladding.The plate is complete with gaskets in EPDM with anti-vibration function for the cladding.The system thus composed has a gap between the cladding slabs of 8 mm.

    BOM OF THE SYSTEM

    Featuring exposed coupling of the cladding, the system consists of: Uprights: T-section (black, anodised); Brackets: L-section anchorage complete with prexing holding spring; Plugs: anchorage suitable for the support;

    Rivets: normalised for xing uprights to brackets; Rivets: normalised for xing plates to uprights; Plate: in STAINLESS steel complete with coloured clips and gaskets.

    DESCRIPTION OF THE SYSTEMFixing on existing support of L-section brackets by means of plugs suitably sized and adapted to the type of support.

    Fixing of special section proles to the brackets by means of rivets, with xed point and sliding point as per the exe-cutive design.In the upright prole there are grooves for housing self-positioning spacers and clips in STAINLESS steel AISI 316 forxing the cladding slabs. For slabs in format 120x60 cm laid horizontally an intermediate upright is envisaged with relatedxing clips.The clips may be of a colour similar to the cladding.The system is complete with gaskets in EPDM with anti-vibration function.The system thus composed may have a gap between the cladding slabs of 4 or 8 mm.

    BOM OF THE SYSTEM

    Featuring exposed coupling of the cladding, the system consists of: Uprights: T-section (with possibility of black anodization); Brackets: L-section anchorage complete with prexing holding spring;

    Plugs: anchorage suitable for the support; Rivets: normalised for xing uprights to brackets; Rivets: normalised for xing clips to uprights; Clips: coloured, in STAINLESS steel AISI 316; Spacers: 4/8 mm; Gaskets: anti-vibration.
