Anchor plates, together with fischer FAZ II Plus bolt anchors and the fischer InnoLock FES cast-in channels, are being used to anchor façade elements permanently and securely to the Estrel Tower – currently under construction in Berlin, Germany.
Designed by the German-American architecture firm Barkow Leibinger, the Estrel Tower in Berlin-Neukölln, will be the tallest high-rise building in Berlin at 176m when completed. The cladding elements are 2.5m wide and weigh approximately 800kg – 1,000kg, depending on their size.
Secure fixing is crucial for the heavyweight façade elements. Each element is anchored in concrete to a depth of at least 85mm using two anchor plates together with two 173mm long FAZ II Plus 16/50 R bolt anchors from fischer Group. The bolts absorb very high-tensile and transverse forces, as well as being quick and easy to install. With a service life of up to 120 years, the FAZ II Plus guarantees a firm hold even after more than a century.
Another fixing method uses the fully hot dip galvanised fischer InnoLock FES RS-S cast-in channels. Here, the substructure brackets are fastened on the front side of the column with the M16 x 80mm channel bolt FBC-S-225. The InnoLock rails are already embedded in the concrete flush with the concrete support. The façade installers use the corresponding channel bolts and nuts to attach the add-on parts. To do this, they turn the channel bolt clockwise by approximately 90° and then apply the specified torque. The façade elements are then positively hooked into a recess in the anchor plates.
The wide, robust toothing of the fischer InnoLock channel and channel bolt creates connections that can withstand the highest loads, even in the longitudinal direction of the channel, thanks to proven positive locking. At the same time, the toothed connection and the low tightening torque facilitate and accelerate secure installation. The patented lip geometry also enables high retention values for tensile, transverse and longitudinal loads. Thanks to a sophisticated functional concept, the channel bolt remains securely connected to the anchor channel even under the highest loads.
