PERFEZIONAMENTO DEI DISPOSITIVI DI ANCORAGGIO DI CAVI PER TSTRUTTORE INCEMENTO ARMATO PRECOMPRESSO

摘要

The invention is concerned with cable couplers which enable cables used in the stressing of contiguous concrete construction units to be joined together with the ends of the units close together. The coupler consists of a housing having at least one blind passage therein of generally rectangular cross-section and with one pair of walls oppositely divergent towards the blind end of the passage which houses a wedge assembly co-operating with the divergent walls and adapted to secure at least one cable end in the housing. The invention also provides for the housing to have a further passage therethrough with a pair of walls oppositely inclined to those of the first mentioned passage so that a cable may be similarly secured in the housing from the opposite direction.
