PUNCHING SHEAR CONCRETE
REINFORCEMENT YOU CAN RELY ON
Cost effective and simple to install: Schöck Bole® SR provides an efficient punching shear reinforcement solution when reinforcing concrete slabs with shear studs. It guarantees optimum force resistance around columns and prevents punching shear failure. The punching shear reinforcement element is easy to install, either at the prefabricating plant or on site.

Increase punching shear strength without increasing concrete slab thickness.
PREVENT PUNCHING SHEAR FAILURE WITHOUT
INCREASING SLAB DEPTH
Flat slabs offer numerous benefits when designing the layout of industrial and commercial buildings. They make it possible to reduce the workload for form work and reinforcement and permit interior finishing right up to the ceiling without any problems, allowing for full use of the ceiling height.
Prevention of punching shear failure is critical for this type of construction and can be resolved efficiently and dependably with Schöck Bole® SR, a punching shear reinforcement consisting of forged double-headed studs and anchors with spacing bars to secure correct positioning. Studs arrive attached to non-structural rails, alleviating the need for on-site welding, and ensuring correct spacing.
STUD RAILS FOR CONCRETE
SLAB REINFORCEMENT
Schöck Bole® SR stud rails are used as punching shear reinforcement in concrete flat slabs, providing the necessary punching shear strength, while allowing maximum ceiling height without the need for drop panels and/or capitols.
Anchor heads reliably transfer the forces
Forged, double-headed studs, in accordance with ASTM 1044-16
Studs arrive attached to nonstructural rails ensuring correct spacing
(ICC-ESR 4656)
Deformed shaft improves bond to concrete
Double-headed configuration can be installed before or after placing slab rebar
Studs are forged not welded, yield strength of 72,500 psi
