Shear Load Connectors

Lockable Dowels

Ancon Lockable Dowels have been designed for use at temporary movement joints. The dowel allows initial shrinkage of the concrete to take place and is then locked in position with a mechanical plate and a controlled amount of epoxy resin. The locked dowel continues to transfer shear, but prevents further movement taking place.

Ancon ESDQ-L20W Lockable Dowel

The dowel component is manufactured from 30mm diameter Duplex stainless steel, but is shorter than the ESDQ-L20 dowel. One end of the dowel is designed to fix into the stainless steel Ancon SKS24 Threaded Anchor cast into the face of the concrete, and the other end features a series of grooves to accept the Locking Plate. The sleeve component is the same as used in the ESDQ-L20.
