Systems, methods, and machines for joining truss foundation components
A coupler for joining truss leg components provides angular adjustability between the respective axis of the leg components. A prolate spheroid-shaped coupler with three channels circumscribing its surface enables the upper leg components to compensate for axial misalignment of driven screw anchors in all directions. A hydraulic crimping device with upper and lower crimping guides registers its position with features on the truss hardware to insure that blind triple crimps are performed consistently each time.
1. A coupler for joining two elongated foundation components along a substantially common axis, the coupler comprising:
a main body portion;
at a first end, a receiving portion projecting away from the main body portion in a first direction for receiving one end of a first elongated foundation component; and
at a second, opposing end, a connecting portion projecting away from the main body portion in a second opposing direction, the connecting portion received in an open end of a second elongated foundation component, the connecting portion comprising a projection having a curved profile with a plurality of orthogonal channels circumscribing the projection, the channels separating the connecting portion into respective sections, and
at least one driving feature extending out from the main body at a base of the connecting portion, the at least one driving feature providing a feature for transmitting torque to the coupler and limiting an extent of penetration of the connecting portion into the second elongated formulation component.
2. The coupler according to claim 1 , wherein the projection has a prolate spheroid-shaped profile.
