Abstract:
1. An expandable splice block configured to mechanically couple a first rod to a second rod, the expandable splice block comprising: a top plate comprising a front surface and a back surface; a bottom plate comprising a first side and a second side, wherein the first side is coupled to the second side by a neck formed by at least two notches extending inward between the first side and the second side, wherein the neck is configured to deform to enable the first side to rotate at least three degrees relative to the second side, and wherein the first side comprises a first threaded hole and the second side comprises a second threaded hole; a first threaded insert threadably coupled to the first threaded hole, wherein the first threaded insert is configured to push the top plate away from the first side as the first threaded insert is threaded towards the top plate; a second threaded insert threadably coupled to the second threaded hole, wherein the second threaded insert is configured to push the top plate away from the second side as the second threaded insert is threaded towards the top plate; and a central axis extending between the first side and the second side of the bottom plate, wherein the central axis runs through at least a portion of the neck, wherein the first side comprises a third threaded hole and the second side comprises a fourth threaded hole, wherein a third threaded insert is threadably coupled to the third threaded hole and a fourth threaded insert is threadably coupled to the fourth threaded hole, wherein the first threaded hole of the first side and the second threaded hole of the second side are located on a left side of the central axis and the third threaded hole of the first side and the fourth threaded hole of the second side are located on a right side of the central axis to enable the threaded inserts to provide leverage relative to the central axis to force the neck to allow the first side to rotate relative to the second side when the first side is located inside of the first rod and the second side is located inside of the second rod.
