PSR (Punching Shear) Studs

Nelson Punching Shear Resistor Studs are used to fabricate reinforcing rails for concrete floor slabs and foundations at the point where columns penetrate through the floor to prevent “punching shear”.

The PSR stud significantly reduces the need for heavy reinforcement and a large column capital under the floor slab.

The PSR studs provide easier installation and ductile performance.

Application Details:

Several studs of an established length and diameter are welded onto a flat bar at specific spacing to extend from the column perimeter into the floor slab. This reduces the amount of reinforcing bar required in the area and reduces column reinforcing congestion resulting in lower costs.

 

There is a clear cover at the top and bottom of the installed studs. The reinforcing stud strip is held off the wooden form by a spacer or ’chair’ to ensure clear cover requirements. The spacer is fastened to the wood form, the floor is then cast and the wooden forms stripped.

 

The PSR stud can also be used as an embedment. by welding a tap stud on the bottom of the flat bar plate. The welded tap stud can be used for suspending electrical, heating, plumbing and sprinkler runs replacing costly drilled or grouted anchors in the floor after casting.
