Material Connections Joining Different Materials 4 Detailed assemblies

Material Connections

Joining Different Materials 4 Detailed assemblies include various materials, a detailer must be aware of connection details that combine these different materials, connections may include: – Concrete to masonry – Structural steel to masonry – Wood to concrete – Wood to masonry – Wood to steel – Steel to concrete – Steel to steel – Concrete panel to steel frame

Concrete to Masonry 4 Concrete plank provides a subbase for concrete finished floor 4 Concrete fin fl is bonded to wall with rebar 4 3” bearing for concrete plank

Structural Steel to Masonry 4 Pocket is provided for the steel beam and filled in after beam is set, leveled anchored to the masonry wall 4 Note 1” dry pack for leveling beam

Structural Steel to Masonry 4 Supporting a steel beam on a masonry pilaster (masonry column built into a wall) 4 Metal plate is set, leveled anchored to the pilaster then the steel beam is welded to the plate

Wood to Concrete 4 Steel saddle is anchored to concrete (precast tilt-up wall with rebar and ties 4 Wood glu-lam beam is fit into saddle

Wood to Masonry 4 Steel saddle is anchored, set and leveled in to the masonry wall with anchor bolts grouted in the cavity of the masonry wall 4 Dry pack is used

Wood to Steel (Beam clearance not a concern below floor joist) 4 Method #1 (Joist resting on top of steel beam): stud bolts are welded to the top of the steel beam, a wood plate is then bolted to the steel beam providing a nailing surface to attach the wood floor joist

Wood to Steel (Beam and Joist at same level) 4 Method #2 (Joist attach to side of steel beam): stud bolts are welded to the top of the steel beam, a wood plate is then bolted to the steel beam, joist hangers are attached to wood plate to hang joist 4 Hanger also welded to beam 4 Wood shrinkage a problem

Connection Methods for Wood to Steel 4 Wood Nailer to Steel beam Wood Jamb to Steel Column

Steel to Concrete 4 Existing concrete wall to receive a load bearing steel beam 4 Two methods: – insert expanded metal shields for bolt attachment – drill holes in concrete and insert an approved epoxy adhesive to secure machine bolts to attach steel plate

Steel to Steel 4 Shop drawings needed for final approval

Concrete Panel to Steel Frame 4 Panel must be attached to and supported to structural steel

Canopy Columns Drawing 4 Design 24” x 24” masonry column 4 Size Rebar and steel ties 4 Size glu-lam beam Steel may be used 4 Add height of wall to bearing support of pilaster 51/8” x 16” F. S. = full size
