Lockable Dowels improve site access,minimize formwork requirements and accelerate the rate of construction.With a Lockable Dowel,there is less requirement for the slabs to be propped or a support corbel to be constructed,as shear load is transferred by the dowel.The time saved by early removal of slab props can be significant.Load Bearing Behaviour of Castin Shear Dowels - Randl Recent shear tests performed with castin rebars,away from the edge,are presented and analysed.A design formula is derived to determine the transverse shear capacity of dowels cast into concrete,based on a modified support modulus method and taking into consideration the concrete yielding,and this is compared with existing theoretical HALFEN SHEAR DOWEL SYSTEMS HSD 13-USThe HSD-LD-ULTRA is a high capacity Lockable Dowel with a design shear strength of up to 30.6 kip.See pages 18-25 for full technical details.HaLFEn HSD-LD-W Lockable Dowel* The dowel component is manufactured from 13/ 16 diameter stainless steel,but is shorter than the HSD-LD dowel.One end of the dowel
