HSD-LD Lockable Dowels
HALFEN HSD-LD Lockable Dowels have been designed for use in temporary movement joints, most commonly found in post-tension concrete slabs. These dowels allow for initial shrinkage to take place and then are locked in position with a mechanical plate and a controlled amount of epoxy resin. When locked, the dowels continue to transfer shear, but prevent further movement from taking place. The use of HALFEN HSD-LD Lockable Dowels can save a significant amount of construction time, labor, and material over other building methods. Concrete shrinkage has traditionally been accommodated by leaving gaps in slabs called "pour-strips" or 'closure-strips.' These strips are filled once movement has ceased; however, until they are filled, the slabs must be temporary supported restricting site access and delaying construction progress.
