Schüco SMC 50.HI, highly thermally insulated, self-supporting, modular aluminium façade system
As a mullion/transom construction for multi-storey façades with an internal and external face width of 50 mm.
Module 1, structural analysis
The load-bearing structure of the façade which transfers the load to the building structure, and also the attachment of the components of the load-bearing structure to one another, consist of rectangular multi-chamber hollow profiles.
The load-bearing construction is on the room side.
All profile edges have a 0.5 mm radius.
The transoms are connected to the mullions using U-shaped T-cleats.
On multi-storey façades, all horizontal joints must be constructed using the joint connectors from the system.
To anchor the load-bearing structure, system components must be used in accordance with structural requirements.
Module 2, function
The function of module 2 is to seal, to provide thermal insulation and to take the glazing / infills. It consists of a PVC-U insulating profile, fitted with engagement grooves for installation in module 1 and inserted glazing rebate gaskets, plus a gasket insert profile around the penetration area where the self-drilling screws fix the pressure plates. The module also has an insulating foam profile rolled into it for increased thermal insulation. To connect the transom modules to the mullion modules, the transom modules must be notched; a transom seal must also be inserted into the centre groove on each side.
Horizontal joints for multi-storey façades must be constructed with expansion joint seals and expansion joint gaskets.
Rebate base ventilation and vapour pressure equalisation are achieved at all four corners of each module field into the mullion rebate. Fit deflector blocks which belong to the system and which are designed for the glass thickness used.
The multi-part glazing rebate gaskets are configured so that they can be divided for the overlap where the profiles join. In order to accommodate different thicknesses of infill, a web can be removed to open up a groove into which a compensating gasket of appropriate thickness can be inserted.
Glazing/infill thicknesses from 24 - 42 mm can be used. All glazing, even in the insert units, lies in the same plane.
Module 3, design
The purpose of module 3 is to seal and hold the glazing and infills. It consists of a pressure plate with two-part glazing gaskets inserted and special self-drilling screws for fixing to the load-bearing structure. The joint between the pressure plates and the load-bearing structure must be designed in accordance with the conditions of the existing general building authority approval. The multi-part glazing gaskets are configured so that they can be separated for field ventilation. The joint areas (transom module to mullion module) must be designed with T-joint covers on both sides; sloping, non-90° attachments must be produced. Joints in the vertical pressure plates must have joint pressure pieces. Cover caps are used to meet architectural requirements.
Design of cover cap: Please describe design
All fixing screws for external use must be grade A2 stainless steel.
