Abstract: A support module interconnects with other support modules to support a number of core elements for encapsulation within a concrete structure. The module has a planar frame defining first and second cutouts. Each cutout has an arc shape so that when modules are assembled, the cutouts of different modules define a circular aperture for closely receiving one of the core elements. Each cutout has a first peripheral arc portion and a concentric second arc portion larger than the first portion. 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 frame having connection elements that to connect with other support modules to securely receive the core elements. The module may include a separately formed arcuate insert fastened to the cutout to provide a smaller aperture.

Abstract: A support module for interconnecting to like support modules serves to support a number of core elements for encapsulation within a concrete structure. The module has a planar frame defining a first cutout and a second cutout. Each cutout has an arc shape, such that the cutouts from different modules define a circular aperture for closely receiving one of the core elements. The frame has extending portions with connection elements that connect with other support modules to securely receive the core elements. The extending portions are located about the periphery of the frame so that they are able to connect to other support modules in four orthogonal directions.
