Mechanism and system for fastening track rail to a substrate and track rail fastening method

A system for fastening track rail comprising:

• a fastening mechanism including a one-piece fastener body formed by a metallic base having a central rail-supporting core and an overmolded non-metallic coating encasing the metallic base, and including an upper side, a horizontally extending lower side, and a rail support surface for supporting a track rail thereon at a location vertically above a substrate;
• the fastening mechanism further including a first metallic pillar positioned at a first location on a first lateral side of the rail support surface, and a second metallic pillar positioned at a second location on a second lateral side of the rail support surface, and the first metallic pillar and the second metallic pillar defining a first vertically extending bore and a second vertically extending bore, respectively, each structured to receive an anchor held fast within the substrate;
• a first coupling mechanism structured to couple a first anchor to the first metallic pillar, and a second coupling mechanism structured to couple a second anchor to the second metallic pillar;
• the overmolded non-metallic coating extending peripherally around each of the first metallic pillar and the second metallic pillar to position vibration-attenuating non-metallic material of the coating horizontally between the metallic base and each of the first metallic pillar and the second metallic pillar;
• and
• the overmolded non-metallic coating further extending between the central rail-supporting core and the horizontally extending lower side to position vibration-attenuating material vertically between the metallic base and the substrate.

A method of fastening a track rail to a substrate comprising:

• positioning a fastening mechanism upon a substrate such that a plurality of anchors within the substrate are received within a plurality of vertically extending bores extending through a plurality of metallic pillars positioned in a one-piece fastener body of the fastening mechanism;
• positioning a track rail in contact with a rail support surface of the fastening mechanism that is located laterally between the plurality of metallic pillars;
• clamping the track rail to the fastening mechanism;
• and
• coupling the plurality of anchors to the plurality of metallic pillars, such that an overmolded non-metallic coating of the one-piece fastener body is positioned in a vibration transmission path horizontally between the plurality of metallic pillars and the metallic base, and positioned vertically between and in contact with each of the substrate and the metallic base, to attenuate vibrations transmitted between the track rail and the substrate.
