Abstract
A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.
Claims34
An expansion joint seal comprising:
- a cover plate,
- an elastically-compressible core having a core bottom surface, and a core top surface,
- a rib piercing the elastically-compressible core at the core top surface,
- a flexible member attached to the cover plate and to the rib,
- the flexible member having a cylindrical second member and a partial open cylinder first member, partial open cylinder first member interlocked about and partially encircling the cylindrical second member, one of the partial open cylinder first member and the cylindrical second member having a ball detent and the other having a mating detent, and
- wherein the rib remains rotatable in relation to the cover plate.

An expansion joint seal comprising:
- a cover plate,
- an elastically-compressible core,
- the elastically-compressible core having a first layer and a second layer,
- a rib positioned between the first layer elastically-compressible core and the second layer core, and
- a flexible member attached to the cover plate and the rib,
- the flexible member having a cylindrical second member and a partial open cylinder first member, partial open cylinder first member interlocked about and partially encircling the cylindrical second member, one of the partial open cylinder first member and the cylindrical second member having a ball detent and the other having a mating detent,
- wherein the rib remains rotatable in relation to the cover plate.
4 more elements
An expansion joint seal comprising:
- a cover plate,
- an elastically-compressible core having a core bottom surface, and a core top surface,
- a rib extending through the elastically-compressible core at the core top surface, the rib extending to the core bottom surface, and
- a flexible member attached to the cover plate and to the rib,
- the flexible member having a cylindrical second member and a partial open cylinder first member, partial open cylinder first member interlocked about and partially encircling the cylindrical second member, one of the partial open cylinder first member and the cylindrical second member having a ball detent and the other having a mating detent, wherein the rib remains rotatable in relation to the cover plate.
