1. An apparatus configured to structurally replace a cracked weld in a nuclear plant, the apparatus comprising:
a first body portion including,
a first gripping portion,opposing rails surrounding a central opening in the first body portion, at least one of the rails including an access opening extending therethrough, the access opening in the form of a substantially spherical seat; a second body portion defining a groove therein, the groove configured to slidably engage the rails of the first body portion so as to interlock with the first body portion, the second body portion including,
a second gripping portion including a second body portion access defined therein, the second body portion access being generally T-shaped; an adjustment portion including,
an elongate body having a first end and a second end, the adjustment portion including an end wall at the second end, a portion of the elongate body and the end wall being configured to be received in the second body portion access such that the second body portion is configured to prevent rotation of the adjustment portion when the first and second body portions are slidably engaged; anda retaining portion including a nut in the form of a ball, the ball configured to be received in the access of the first body portion, and the first end of the elongate body configured to extend through the access and into the nut, such that the apparatus is substantially self-aligning; wherein the adjustment portion is configured to exert force on the slidably engaged first and second body portions, wherein the adjustment portion is further configured to increase or decrease the force exerted on the slidably engaged first and second body portions, and wherein when the adjustment portion increases the force exerted on the slidably engaged first and second body portions, a distance between the first and second gripping portions decreases. |
