ABSTRACT:
A method of preparing the upper end of a concrete column containing elongated reinforcing elements for connection to a cast-in-place beam supported by the column. The method comprises the steps of determining the elevation at which the column is to engage the beam, severing the column a distance above said elevation, axially core drilling the column to said elevation, scoring the outside of the column at the elevation by use of an abrasive saw, crushing the shell of the column about the area previously core-drilled to fracture the concrete and free the elongated reinforcing elements, and finally bending the elongated reinforcing elements into a position in which they tie into the cast-in-place beam structure to be supported by the column.
