All the strands of the anchor are simultaneously put under tension in a single block with their clamping wedges.
In function of the drilling diameter the plate will be sized. The range varies from 2 to 12 strands. The heads used are the same as those used in structure cables and therefore tested in accordance to the current regulations, the steel of the heads is conforming to the EN 10025 standar ds.
The head allows to tension simultaneously all the strands making up the single anchor. The heads of our production are made in C45 with defined geometries, as per the tables below. Automatic production plants still allow us to process any type of geometry according to the requirements of individual customers.
We produce heads for tie rods strand 0.6“ and 0.5” and our heads are provided with their anchor wedges made in compliance with current standards too.
The heads will be accommodate in a suitable distribution plate suitably dimensioned according to tons of throw and the drilling diameter. We also produce threaded heads for any re-tensioning.
