Install in true alignment and proper relationship to joints and adjoining finished surfaces
measured from established lines and levels.
Adjust for differences between actual structural gap and nominal design gap due to
ambient temperature at time of installation.
Cut and fit ends to accommodate thermal expansion and contraction of metal without
buckling of frames.
Locate anchors at interval recommended by manufacturer, but not less than 3 inches (75
mm) from each end and not more than 24 inches (600 mm) o.c.
Seals: Install elastomeric seals and membranes in frames to comply with manufacturer's written
instructions. Install with minimum number of end joints.
1.
2.
3.
Provide in continuous lengths for straight sections.
Seal transitions. Vulcanize or heat-weld field-spliced joints as recommended by
manufacturer.
Installation: Mechanically lock seals into frames or adhere to frames with adhesive or
pressure-sensitive tape as recommended by manufacturer.
D.
Compression Seals: Apply adhesive or lubricant adhesive as recommended by manufacturer
before installing compression seals.
E.
Epoxy-Bonded Seals: Pressurize seal for time period and to pressure recommended by
manufacturer. Do not overpressurize.
F.
Install with hairline mitered corners where expansion joint cover assemblies change direction or
abut other materials.
G.
Terminate exposed ends of expansion joint cover assemblies with field- or factory-fabricated
termination devices.
H.
Elastomeric Concrete: Install according to manufacturer's written application instructions.
I.
Fire-Resistance-Rated Assemblies: Coordinate installation of expansion joint cover assembly
materials and associated work, so complete assemblies comply with performance requirements.
1.
J.
3.4
Fire Barriers: Install fire barriers to provide continuous, uninterrupted fire resistance
throughout length of joint, including transitions and field splices.
Moisture Barrier Drainage: If indicated, provide drainage fittings and connect to drains.
PROTECTION
A.
Do not remove protective covering until finish work in adjacent areas is complete. When
protective covering is removed, clean exposed metal surfaces to comply with manufacturer's
written instructions.
B.
Protect the installation from damage by work of other Sections. Where necessary due to heavy
construction traffic, remove and properly store cover plates or seals, and install temporary
protection over expansion joint cover assemblies. Reinstall cover plates or seals prior to
Substantial Completion.
