  • Patent number: 4979462
    Abstract: The locating of structural members disposed within the interstices of a concrete member can be accomplished by employing at least one indicator capable of showing the position of the structural member. The indicator also can show the directional location of the support members. The indicator of the present invention generally connects to a post member. This post member provides vertical support for the indicator system. A clamping assembly is attached to the post member and connects the structural member to the indicator system for fixing the location of the structural member. The clamping system can also identify the location of the structural member, and the indicator can then be provided to show the directional line of the structural member. Typically, the post member is sized to a predetermined length so that the longitudinal dimension of the indicator system corresponds to the thickness of the concrete member.
