Standard Fischer standard soffit designs up to 400mm using ex stock L and T profiles to support most soffit materials. Assembly of aluminium parts using self-drilling stainless Ejot tek screws.
Soffit design is constructed using FEA software to calculate deflection and the bending moments in the components. Through this analysis it is possible to design non-standard soffits up to 800mm in depth.
Fixing into concrete soffits, is generally a fixing zone where the concrete is classified as ‘cracked’, unless otherwise specified by the project engineer. Fixing into cracked concrete is an ETA, option 1 application, ranges such as; FAZ II through bolts or FBS II concrete screws would generally be specified by Fischer engineering department.
It is also possible to use standard helping hand brackets is preferred.
Where the soffit boards are joined together, either the 110mm, or the 60mm faced T rail, provides the correct dimensions to all the major board manufacturers specification, relating to surface area in contact with the panel, and movement joint between the abutting panels. Depending on the material type, generally support rails are set at 500mm to 600mm - for centre panel support generally use the L rail 51x61mm section.
FischerBWM facade systems are designed and manufactured to Eurocode 9. UK accreditation approvals through the new Winmark Approval, by Wintech and the BBA are confirmation of Eurocode design and manufacture processes.
