Title:
Expansion Joint
Covers
Interior &
Exterior-Parking/Stadium
Division 5
Presented by Lee Seaman
Expansion joint openings or gaps
are designed into your building to allow for movement. The size of
the opening is determined based on the movement requirements. Once
the gap is calculated the design challenge is to incorporate a cover
plate system that will conceal the opening while still allowing for
the proper movement. There are aluminum cover plates as well as
gasket style flush systems available for interior wall, floor and
ceiling conditions.
Exterior expansion joint systems
must handle the movement but also must prevent water from
penetrating into the building. These systems include both exterior
vertical and roof cover systems and can be fabricated with factory
miters to ensure a smooth transition from the roof cover to the
exterior vertical.
Parking garages and plaza decks
create a unique challenge in that joint system must provide a
watertight seal while accommodating the increased loading and impact
conditions of vehicular traffic. There is a new Zip Block model,
which is a one piece EPDM style system. There are also various
gasket systems and heavy duty aluminum cover plate models to meet
the specific project conditions.
There is one learning unit and one
HSW credit available.
