Abstract
Abstract An expansion joint for bridges and similar structures comprising an elastomeric sealing element, anchoring means gripping the sealing element and resin mortar connecting the anchoring means to the structure. The resin mortar is comprised of a mixture of ureide and epoxy resins and aggregate. The anchoring means has rods embedded in the resin mortar to distribute stresses therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
48 words
An expansion joint for a concrete roadway or the like comprising an expandable sealing element, a resin mortar comprised of coarse aggregate and a resin composition and means anchoring the expandable sealing element to the resin mortar, said resin composition comprising a mixture of epoxy resin and polyureide.
Claim 2
Dependent Claim
48 words
An expansion joint for a concrete roadway or the like comprising an expandable sealing element, a resin mortar comprised of coarse aggregate and a resin composition and means anchoring the expandable sealing element to the resin mortar, said resin composition comprising a mixture of epoxy resin and polyureide.
Claim 3
Dependent Claim
46 words
An elastomeric expansion joint as set forth in claim 1 in which said anchoring means comprises a generally flat surface and one or more rods extending from said flat surface in a direction generally lenthwise along the joint, said rods being embedded in said resin motar.
Claim 4
Dependent Claim
42 words
An elastomeric expansion joint as set forth in claim 2 in which said flat surface is substantially vertical and said one or more rods extend from said flat surface laterally outwardly from said expandable sealing element and generally lengthwise along the joint.
Claim 5
Dependent Claim
38 words
An elastomeric joint as set forth in claim 3 in which said one or more rods comprise a sinusoid, said sinusoid being attached to said flat surface at a plurality of points along the length of the joint.
Claim 6
Dependent Claim
16 words
An elastomeric sealing element as set forth in claim 4 in which said sinusoid is metal.
Claim 7
Dependent Claim
30 words
An expansion joint as set forth in claim 2 in which said resin mortar comprises 15 to 45% of said resin composition and 55 to 85% of said coarse aggregate.
Claim 8
Dependent Claim
30 words
An expansion joint as set forth in claim 2 in which said resin mortar comprises 15 to 25% of said resin composition and 75 to 85% of said coarse aggregate.
Claim 9
Dependent Claim
21 words
An expansion joint as set forth in claim 2 in which the coarse aggregate comprises a mixture of aggregates and sand.
Claim 10
Dependent Claim
38 words
An expansion joint as set forth in claim 2 in which said resin composition comprises 45 to 80% polyureide and 20 to 55% of epoxy resin, the percentages being based on the total of polyureide and epoxy resin.
Claim 11
Dependent Claim
19 words
An expansion joint as set forth in claim 8 in which said resin composition also contains plasticizer and/or diluent.
Claim 12
Dependent Claim
59 words
An expansion joint as set forth in claim 2 in which the resin is obtained by reaction of Component A and Component B, wherein Component A is a mixture of (1) a liquid polyisocyanate prepolymer containing 2 to 6% of NCO groups blocked by a phenol (2) an epoxy resin and Component B comprises an aliphatic or cycloaliphatic diamine.
Claim 13
Dependent Claim
29 words
An concrete roadway having a gap thereon, and an expansion joint according to claim 1 covering over said gap, the resin mortar adhering said anchoring means to the roadway.
