Abstract

A seismic/expansion joint seal and cover comprises a cover plate, and a central spine extending downwardly from said cover plate. At least one layer of a resilient compressible foam sealant is provided on each side of the spine.

Claims

1. A seismic/expansion joint seal and cover comprising:

a cover plate;

a central spine extending downwardly from said cover plate, said cover is detachable from said spine, said cover is screwed to said spine; and

at least one layer of a resilient compressible foam sealant on each side of said spine, said spine is composed of two mirror-image generally C-shaped members, each of which has a lower base flange, an upper base flange into which said cover is screwed, and a flat web extending between the flanges, against which said foam sealant is positioned, said upper flange of each said C-shaped members is the laterally extending portion of a right angle member that is affixable to said web at selected heights.

2. A joint seal and cover as claimed in claim 1, wherein said C-shaped members are separated by a strip of incompressible foam.

3. A joint seal and cover as claimed in claim 1, wherein a bead of sealant is applied between said spine and said cover.

4. A seismic/expansion joint seal and cover comprising:

a cover plate;

a central spine extending downwardly from said cover plate; and

at least one layer of a resilient compressible foam sealant on each side of said spine, said compressible foam layer has a low modulus elastomeric sealant applied to the top surface thereof.

5. A joint seal and cover as claimed in claim 4, wherein a bead of sealant is applied between said spine and said cover.

6. A seismic/expansion joint seal and cover comprising:

a cover plate;

a central spine extending downwardly from said cover plate, said cover is detachable from said spine; and

at least one layer of a resilient compressible foam sealant on each side of said spine, said compressible foam layer has a low modulus elastomeric sealant applied to the top surface thereof.

7. A seismic/expansion joint seal and cover comprising:

a cover plate;

a central spine extending downwardly from said cover plate, said cover is detachable from said spine, said cover is screwed to said spine; and

at least one layer of a resilient compressible foam sealant on each side of said spine, said spine is composed of two mirror-image generally C-shaped members, each of which has a lower base flange, an upper base flange into which said cover is screwed, and a flat web extending between the flanges, against which said foam sealant is positioned, said compressible foam layer has a low modulus elastomeric sealant applied to the top surface thereof.

8. A seismic/expansion joint seal and cover comprising:

a cover plate;

a central spine extending downwardly from said cover plate, said cover is detachable from said spine, said cover is screwed to said spine; and

at least one layer of a resilient compressible foam sealant on each side of said spine, said spine is composed of two mirror-image generally C-shaped members, each of which has a lower base flange, an upper base flange into which said cover is screwed, and a flat web extending between the flanges, against which the said foam sealant is positioned, said compressible foam layer has a low modulus elastomeric sealant applied to the top surface thereof, said C-shaped members are separated by a strip of incompressible foam.
