Patent ID: 7281356

Claim:
A support module for interconnecting to like support modules for supporting a plurality of core elements for encapsulation within a concrete structure comprising: a planar frame defining a first cutout and a second cutout facing different directions such that each is operable to engage a different like support module; each cutout having an arc shape such that a plurality of cutouts of different modules define a circular aperture for closely receiving one of the core elements; each cutout having a first peripheral arc portion and a second arc portion larger than the first portion and concentric therewith, such that the first portion provides an aperture of a first diameter, and upon removal of the first portion, the second portion provides an aperture of a larger second diameter; the first peripheral arc portion and a second arc portion being formed of a single material as a unitary element; the frame having connection elements operable to connect with other support modules to securely receive the core elements; and wherein the first arc portion is formed separately from the frame.
