Installation of Dayton Shear Resistance is quick and easy. DSR rails can normally be installed around a column/slab connection in less than five minutes. Typical Installation Sequence:
- Attach the furnished chairs to the base plate of each SRS rail and place a chair top over the chairs at each end of the DSR rail.
- Properly position the DSR rails on the formwork as per placement drawings.
- Nail the chairs to the formwork using the blind holes in each chair leg.
- Repeat Steps 1, 2 and 3 for each DSR rail.
After the DSR rails are in place, the rebar, post-tensioning tendons, conduit and other embedded items may be set in the form. Since the tops of the DSR rails are open, it is easy to place rebar or tendons between the studs.
1. Dayton Shear Resistance must be placed and remain vertical in the slab.
2. Equally space DSR rails when two or more are required on a single column face.
