lip of the roof 12 along the front face of the building the regular spacing between the anchor brackets 51 corresponds to the width of the glazing panels 4 similarly the lower anchor brackets 61 are fitted along the front edge of the floor slab 11 with a uniform spacing corresponding to the width of the panels 4 note that for the sake of clarity not all of the anchor brackets 51 61 are individually labelled in the figures then starting at the right hand end of the curtain wall as shown in fig1 the pre prepared fibre linear tensile elements 2 are erected in fig1 most of the erection operation has taken place in relation to the leftmost fibre linear tensile element 2 a it is shown being lifted using an electric winch 72 which has its winch cable 73 attached to the upper end termination 52 the end termination 52 is fixed to the anchor bracket 51 by using nut 53 at the bottom end the end termination 62 is fitted to its anchor bracket 61 by using the nut 63 thus the fibre linear tensile element 2 a is installed in position next to the already installed fibre linear tensile element 2 b as shown for fibre linear tensile element 2 b the height of the first clamping device 3 b 1 is checked with a laser level 74 if necessary the.
