Claims12
An expansion joint system, comprising:
- an elongated core,
- the elongated core composed of a resiliently compressible foam,
- the elongated core is coated with an elastomer,
- the elongated core having an elongated core longitudinal axis,
- the elongated core having an elongated core longitudinal length,
- the elongated core having an elongated core top,
- the elongated core having an elongated core bottom,
- the elongated core having an elongated core height intermediate the elongated core top and the elongated core bottom,
- the elongated core having an elongated core first side,
- the elongated core first side being generally perpendicular to the elongated core top,
- the elongated core having an elongated core second side,
- the elongated core second side being generally perpendicular to the elongated core top;
- and
- three longitudinal load-transfer members,
- each of the three longitudinal load-transfer members being incompressible,
- each of the three longitudinal load-transfer members having a longitudinal load-transfer member axis,
- each of the elongated core longitudinal axes and the longitudinal load-transfer member axes being parallel,
- each of the three longitudinal load-transfer members having a longitudinal load-transfer member length,
- each of the three longitudinal load-transfer members bonded to the elongated foam core at the elongated core top, and
- each of the three longitudinal load-transfer members spaced apart between the elongated core first side and the elongated core second side.
