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.

First claim

What is claimed is:

1. An expansion joint seal comprising:
a cover plate,
a rib,
an elastically-compressible core having a core bottom surface, and a core top surface,
the rib piercing the elastically-compressible core at the core top surface,
wherein the rib remains rotatable in relation to the cover plate; and
a first stabilizer extending into the elastically-compressible core from an end of the rib opposite the cover plate on a first side of the rib.

2. The expansion joint seal of claim 1 , wherein at least the rib does not extend to the core bottom surface.

3. The expansion joint seal of claim 1 , wherein the rib extends to beyond the core bottom surface.

4. The expansion joint seal of claim 1 , wherein the cover plate has a cover plate length, the elastically-compressible core has a core length, and the cover plate length and the core length being equivalent.

5. The expansion joint seal of claim 4 , further comprising:
a force transfer plate having a force transfer plate length, the force transfer plate being fixedly attached to the rib, the force transfer plate providing upward support to the elastically-compressible core,
the force transfer plate maintained in position by connection to the elastically-compressible core and adapted to contact one or more points on a substrate,
and
the cover plate length and the force transfer plate length being equivalent.

6. The expansion joint seal of claim 5 , further comprising:
a second elastically-compressible core, the second elastically-compressible core having a second core body density;
wherein the elastically-compressible core has a core body density, the core body density being unequal to the second core body density;
the second body of elastically-compressible core adjacent the elastically-compressible core.

7. The expansion joint seal of claim 5 , further comprising:
an impregnation, the impregnation impregnated into the elastically-compressible core, the impregnation selected from at least one of a fire retardant and a water inhibitor.

8. The expansion joint seal of claim 5 , wherein the force transfer plate includes at least one pointed downwardly depending extension from a bottom of the force transfer plate.

9. The expansion joint seal of claim 5 , further comprising a compression spring, the compression spring connected to the rib and extending laterally into the elastically-compressible core.

10. The expansion joint seal of claim 9 , further comprising a cylindrical housing about the compression spring.

11. The expansion joint seal of claim 10 , wherein the first layer has a first density and the second layer has a second density.

12. The expansion joint seal of claim 9 , further comprising an internal membrane, the internal membrane extending through the elastically-compressible core above the core bottom surface and above the core top surface, the internal membrane positioned between a first side of the elastically-compressible core and the second side of the elastically-compressible core.

13. The expansion joint seal of claim 12 , where the internal membrane comprises an extruded gland.

14. The expansion joint seal of claim 9 , further comprising a membrane adjacent the elastically-compressible core at the core surface top extending from a first side of the elastically-compressible core to a second side of the elastically-compressible core.

15. The expansion joint seal of claim 1 , further comprising:
an elastomeric coating adhered to the elastically-compressible core at the core top surface.

16. The expansion joint seal of claim 1 , further comprising:
an impregnation, the impregnation impregnated into the elastically-compressible core, the impregnation selected from at least one of a fire retardant and a water inhibitor.

17. The expansion joint seal of claim 1 , further comprising:
a tether attached to the elastically-compressible core and to the cover plate.

18. The expansion joint seal of claim 1 , wherein the cover plate is constructed of multiple cover plate layers.

19. The expansion joint seal of claim 18 , wherein at least one the multiple cover plate layers is a replaceable wear surface.

20. The expansion joint seal of claim 1 , further comprising:
a compressible spacer at an end of the cover plate.

21. The expansion joint seal of claim 1 , wherein the flexible member has a tensile strength not in excess of 344.7 kPa.

22. The expansion joint seal of claim 1 , wherein the rib is composed in part of one of a hydrophilic material, a hydrophobic material, a fire-retardant material, an electrically conductive material, a carbon fiber material, and an intumescent material.

23. The expansion joint seal of claim 1 , wherein the elastically-compressible core is composed in part of one of a hydrophilic material, a hydrophobic material, a fire-retardant material, a sintering material.

24. The expansion joint seal of claim 23 , wherein the elastically-compressible core is laterally compressed 10%-85%.

25. The expansion joint seal of claim 1 , where the elastically-compressible core has an uncompressed density of 50-300 kg/m 3 .

26. The expansion joint seal of claim 1 , wherein the elastically-compressible core includes a foam having 90-200 pores per linear inch.

27. The expansion joint seal of claim 1 , further comprising an intumescent body contacting the elastically-compressible core.

28. The expansion joint seal of claim 1 , wherein the elastically-compressible core contains fire resistant materials.

29. The expansion joint seal of claim 1 , further comprising a radio frequency identification device in contact with one of the cover plate, the rib, the elastically-compressible core, and the flexible member.

30. The expansion joint seal of claim 1 , further comprising a spring within the elastically-compressible core and adjacent the rib.

31. The expansion joint seal of claim 1 , wherein the elastically-compressible core has a width greater at the core surface top than a width of the elastically-compressible core at the core bottom surface.
