Expansion joint cover

Claim 2

An expansion joint comprising a. a pair of elongate spaced apart block members b. an expansion joint cover member overlying said spaced apart block members, said cover member having a pair of elongate strips, each strip having a first elongate edge, said elongate edges being spaced apart from one another and overlying said elongated block members, flexible means overlying and joining said first elongate edges, said expansion joint cover member being characterized in that said elongate strips have corrugations transverse to the direction of said elongate edges, c. fastening means for attaching said strip to said underlying elongated block members, said elongate strips having sufficient resiliency to allow for expansion transverse to the corrugations.

Claim 3

An expansion joint cover comprising: a. a pair of elongate and corrugated strips spaced from one another along their elongate edges with the axis of said corrugations lying transversely to the axis of said elongation, b. an elongate strip of flexible material overlying and joining said corrugated strips in a spaced apart relationship, c. a first and second covering means for enclosing each of said corrugated strips in an elongate envelope, with said first covering means attached along one longitudinal edge to said strip of flexible material, and said second covering means attached along one longitudinal edge to the other elongate edge of said strip of flexible material, so that said corrugated strips are mounted within said covering means and attached to said strip of flexible material with their longitudinal axes parallel to one another in a spaced apart relationship.

Claim 4

An expansion joint cover comprising: a. a pair of elongate and corrugated strips spaced from one another along their elongate edges with the axis of said corrugations lying transversely to the axis of said elongation, b. an elongate strip of flexible material overlying and joining said corrugated strips in a spaced apart relationship, c. a first and second covering means for enclosing each of said corrugated strips in an elongate envelope, with said first covering means attached along one longitudinal edge to said strip of flexible material, and said second covering means attached along one longitudinal edge to the other elongate edge of said strip of flexible material, so that said corrugated strips are mounted within said covering means and attached to said strip of flexible material with their longitudinal axes parallel to one another in a spaced apart relationship.

Claim 5

An expansion joint as claimed in claim 2 wherein said covering means comprises a strip of waterproof material which is folded upon itself along its longitudinal axis, said material being of sufficient with to completely cover said corrugated strip, when said corrugated strip is inserted between the folds of said material.

Claim 6

An expansion joint as claimed in claim 2 wherein said covering means comprises an extruded plastic coating, said coating completely covering the corrugated strip and completely filling the voids of said corrugation on at least one side of said strip to provide a relatively flat surface thereon.

Claim 7

An expansion joint cover comprising a pair of elongate strips, each strip having a first elongate edge, said first elongate edges being spaced apart from one another, flexible means joining said first elongate edges, said expansion joint cover being characterized in that said elongate strips have corrugations transverse to the direction of said elongate edges, and having sufficient resiliency to allow for expansion transverse to the corrugations, said cover also having a second relatively wide overlying elongate strip of material axially aligned with said first elongate strip of material and attached to said first strip along its center portion, said relatively wide strip being of sufficient width to overhang beyond the corrugated strips attached to each side of the first elongate strip.

Claim 8

An expansion joint cover comprising a pair of elongate strips, each strip having a first elongate edge, said first elongate edges being spaced apart from one another, flexible means joining said first elongate edges, said expansion joint cover being characterized in that said elongate strips have corrugations transverse to the direction of said elongate edges, and having sufficient resiliency to allow for expansion transverse to the corrugations, said cover also having a second relatively wide overlying elongate strip of material axially aligned with said first elongate strip of material and attached to said first strip along its center portion, said relatively wide strip being of sufficient width to overhang beyond the corrugated strips attached to each side of the first elongate strip.

Claim 9

An expansion joint cover as claimed in claim 5 wherein said first strip is a relatively thick insulating material.

Claim 10

An expansion joint cover as claimed in claim 5 wherein said relatively wide elongate strip is a laminate formed of a plastic which is bonded to an elastomeric base.

Claim 11

An expansion joint cover comprising a. a relatively thick closed cell elongated strip of insulating material, b. first and second elongated and corrugated strips, said strips having the axes of their corrugations transverse to their longitudinal axis, c. a first and second waterproof envelope for completely covering said corrugated strips, each of said envelopes having a seam edge defined along one side of said envelope and adjacent to the corrugated strip, d. a relatively wide elongated strip axially aligned with said insulating strip and overlying said insulating strip and said corrugated strips, said seam edge of said first envelope being mounted between said relatively wide strip and said insulating strip and axially aligned therewith, said seam edge of said second envelope being spaced apart and mounted between said relatively wide strip and said insulated strip and axially aligned therewith, e. said insulating strip being bonded across its entire length to said relatively wide strip, with said seam edges of first and second envelopes bonded therebetween on each edge of said insulated strip with the corrugated strips extending outwardly beyond the bond.

Claim 12

An expansion joint cover comprising a. a relatively thick closed cell elongated strip of insulating material, b. first and second elongated and corrugated strips, said strips having the axes of their corrugations transverse to their longitudinal axis, c. a first and second waterproof envelope for completely covering said corrugated strips, each of said envelopes having a seam edge defined along one side of said envelope and adjacent to the corrugated strip, d. a relatively wide elongated strip axially aligned with said insulating strip and overlying said insulating strip and said corrugated strips, said seam edge of said first envelope being mounted between said relatively wide strip and said insulating strip and axially aligned therewith, said seam edge of said second envelope being spaced apart and mounted between said relatively wide strip and said insulated strip and axially aligned therewith, e. said insulating strip being bonded across its entire length to said relatively wide strip, with said seam edges of first and second envelopes bonded therebetween on each edge of said insulated strip with the corrugated strips extending outwardly beyond the bond.

Claim 13

An expansion joint cover as claimed in claim 8 wherein said elongated and corrugated strip is formed of plastic.

Claim 14

An expansion joint cover as claimed in claim 8 wherein said relatively wide elongated strip is a laminate formed of a layer of plastic which is bonded to an elastomeric base.

Claim 15

An expansion joint cover as claimed in claim 8 wherein said envelope comprises a strip of waterproof material which is folded upon itself along its longitudinal axis, said material being of sufficient width to completely cover said corrugated strips and extend beyond to create said seam edge when said corrugated strip is inserted between the folds of said material.
