Options to fix a balustrade glazing
Possible types of mounting for balustrade glazing with a width of 1500 x 1250 mm are described here.
The clamping height should be 150 mm. The remaining pane height is 1100 mm. The line load is 1 kN/m.
Model 1, Elast. line supports
If the glass within the clamped area is also considered, an upper and lower clamping line by elastic line supports can be used.
These two bearing lines now take over the introduced bending moment via their distance.
Model 2, Formation of a 2nd geometry structure
For the second option, the clamping area is formed by a separate geometry structure. An area support can now be applied here.
Model 3, Clamping via clamp type 11, glass shoe
A type 11 parametric ‘glass shoe’ clamp is adapted to the width of the pane and the height of the clamp.
The advantage of this bearing option is that not only the clamping surface but also any edge protection in the clamping area can be applied directly.
Any torsional rigidity to be applied to the glass shoe construction could also be taken into account via the one base point.
Model 4, Simplified clamp condition
Another alternative is to take away the rotational degree of freedom for the element nodes at the transition into the glass shoe using type 5. In this case, the pane cannot rotate here, as the degrees of freedom have been taken away, but it can pull out of the notch. The disadvantage of this approach is that the sandwich behaviour in the glass clamping is neglected. The restraint is formed not only from the torsional degree, but also from the bending moment, which is formed in the direction of the pane with the distance between the neutral line of the panes. In the case of an approach without a shear effect, this component is zero. However, if a shear effect for the PVB film is also used, this results in an additional restraint that is not taken into account with this approach.
Model 5, Individual balustrade clamps of type 11
Another option for fastening the glass is using the type 11 clamp bracket. These already parametrically available designs can be directly adjusted and attached to the desired width and height.
This also achieves a quasi-continuous clamping effect, but now with the locally formed stress peaks.
