ABSTRACT:
A nail structure for providing a support surface for subsequent mounting and positioning of elevational rods for utilization particularly in surveying situations. The nail structure includes a first and second spike member orthogonally mounted to a lower or first leg of a generally triangular support truss head when the head is mounted to a main body support, wherein the main body support provides a planar support surface and includes a projection formed at an upper terminal end of the main body support to provide a planar impact head surface for permitting directing of the nail into various structural components such as utility poles. A further improved embodiment of the instant invention includes a benchmark nail structure, wherein a body member is formed with planar body sides for positioning indicator rods utilized in surveying. A coaxially arranged and forwardly extending shank includes a forwardly pointed tip defining a recess positioned along the shank extending rearwardly of the forwardly pointed tip to enhance engagement of the nail structure. The nail member includes an impact head orthogonally mounted to the body component, with the body component defining a top surface orthogonally arranged relative to the coaxially aligned main body and shank, with the top surface including a sighting dimple mounted in coaxial alignment with the shank to define a sighting mark for use by surveyors permitting sighting of linear sighting lines.
