Floor Panel Bears on Column at Standoff
Upper column and panels bear on standoff. Standoff bears on column below. Standoff consists of an upper bearing plate welded to an alignment guide and a lower bearing plate welded to a standoff. The alignment guide nests inside the standoff. Positive connection of bearing plates is made to columns with epoxied threaded rods or partially-threaded screws. Positive connection of panel to bearing plate is made with welded threaded rods.
Purpose: Transfer of vertical load from floor panels and upper column to wood column below.
- Capacity is controlled by perpendicular-to-grain bearing or rolling shear capacity of floor or roof panel, or as specified by manufacturer.
- This connection is unique to single-point support of mass timber panels with two-way span capability such as CLT or SCL-CLT.
- Constructability can be affected by the need for temporary bracing of column.
- Steel connection assembly pieces are pre-installed on columns.
- Consider that mechanical connection between alignment guide and standoff may be required if net uplift exists at upper column.
- Proprietary options exist; possible suppliers include Rothoblaas.
