Material Connections

Material Connections

Joining Different Materials 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 Concrete plank

provides a sub-base for concrete finished floor

Concrete fin fl is bonded to wall with rebar

3” bearing for concrete plank

Structural Steel to Masonry Pocket is provided

for the steel beam and filled in after beam is set, leveled and anchored to the masonry wall

Note 1” dry pack for leveling beam

Structural Steel to Masonry Supporting a steel beam

on a masonry pilaster (masonry column built into a wall)

Metal plate is set, leveled and anchored to the pilaster then the steel beam is welded to the to the plate

Wood to Concrete

Steel saddle is anchored to concrete (pre-cast tilt-up wall with rebar and ties

Wood glu-lam beam is fit into saddle

Wood to Masonry

Steel saddle is anchored, set and leveled in to the masonry wall with anchor bolts grouted in the cavity of the masonry wall

Dry pack is used

Wood to Steel (Beam clearance not a concern below floor joist)

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)

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

Hanger also welded to beam Wood shrinkage a problem

Connection Methods for Wood to Steel Wood Nailer

to Steel beamWood Jamb to Steel Column

Steel to Concrete

Existing concrete wall to receive a load bearing steel beam

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

Shop drawings needed for final approval

Concrete Panel to Steel Frame

Panel must be attached to and supported to structural steel

Canopy Columns Drawing Design 24” x 24”

masonry column Size Rebar and steel

ties Size glu-lam beam

Steel may be used Add height of wall

to bearing support of pilaster

F.S.= full size
