Cable tray support assembly

A reinforcing structure for supporting a joint of two cable tray sections, wherein each of the two cable tray sections includes a side rail having a planar body member, a bottom edge and a top edge, comprising:

• a top member;
• a body member extending substantially perpendicularly from the top member;
• a bottom member extending substantially perpendicularly from the body member;
• and
• a splice plate configured for attachment to the side rails of the two cable tray sections,
• wherein the bottom member is configured for mounting on the structural support member,
• wherein the bottom member is configured to receive the bottom edge of the side rail,
• wherein the top member includes an inside edge configured to support the planar body member of the side rail when the bottom edge of the side rail is received into the bottom member, and
• wherein the inside edge of the reinforcing structure is configured to abut an outside surface of the splice plate.

A cable tray system, comprising:

• a first cable tray section including a first side rail having a first planar body member, a first bottom edge and a first top edge;
• a second cable tray section including a second side rail having a second planar body member, a second bottom edge and a second top edge;
• a splice plate configured for attachment to the first side rail and the second side rail;
• and
• a reinforcing beam for supporting the first cable tray section, the second cable tray section, and the splice plate when the first and second cable trays are positioned over a structural support member,
• wherein the reinforcing beam comprises:
• a top member;
• a body member extending substantially perpendicularly from the top member;
• and
• a bottom member extending substantially perpendicularly from the body member,
• wherein the bottom member is configured for mounting on the structural support member,
• wherein the bottom member is configured to receive the first bottom edge of the first side rail and the second bottom edge of the second side rail, and
• wherein the top member includes an inside edge configured to support the splice plate when first bottom edge of the first side rail and the second bottom edge of the second side rail are received into the bottom member of the reinforcing beam.

A device for supporting a cable tray expansion joint formed over a structural support member, comprising:

• a top member for abutting a splice plate joining a first cable tray section and a second cable tray section;
• a body member extending substantially perpendicularly from the top member;
• and
• a bottom member formed transversely to the body member,
• wherein the bottom member is configured for mounting on the structural support member,
• wherein the body member and the bottom member are configured to form a cavity to slidingly receive a bottom edge of the first cable tray section and a bottom edge of the second cable tray section.
