Abstract
An expansion joint system is provided which uses magnets to hold a cover plate to a base frame of a substrate. The expansion joint system allows the magnets to slide over the base frame/cover plate during normal movements of the substrates without applying tension to the cover plate. In a seismic or other disruptive event, the cover plate is tethered to the building via a bungee.
Claims20
An expansion joint system comprising:
- a cover plate magnetically connectable to a base frame on opposing substrates;
- one or more magnets connected to the cover plate wherein the magnets are selected to provide a secure connection between the cover plate and the base frame, the magnets allowing for sliding movement across the surface of the base frame to accommodate small movements of the substrates without applying strain to the cover plate;
- the cover plate having a bent return shape at each lengthwise end, the bent return shape forming a channel;
- one or more stiffening bars positioned along the length of the cover plate, the stiffening bars being connected to the cover plate by being held in place within the channel.

An expansion joint system comprising:
- a cover plate magnetically connectable to a base frame on opposing substrates;
- one or more magnets connected to the cover plate wherein the magnets are selected to provide a secure connection between the cover plate and the base frame, the magnets allowing for sliding movement across the surface of the base frame to accommodate small movements of the substrates without applying strain to the cover plate;
- and
- the cover plate comprising two lifting ramps connected to a rear face of the cover plate, the lifting ramps being angled to allow the cover plate to be urged away from the opposing substrates in response to movement of the substrates contacting one or both of the two lifting ramps, the lifting ramps operable to prevent damage to the joint and substrates during seismic events or other conditions.
1 more element
An expansion joint system comprising:
- a bracket attachable to a first building substrate;
- a cover plate magnetically connectable to the bracket by a magnet positioned on one or both of the bracket and the cover plate, the magnetic connection between cover plate and bracket operable to resist lifting forces applied by wind, the cover plate having an upward bend at a proximal end and a downward distal end bend;
- a spring engaged with the proximal end of the cover plate and engaged with a second building substrate, the spring urging the distal end of the cover plate in a downward direction towards the first building substrate.
