Abstract: A material having fibers in a curable matrix is applied as a reinforcement to a vertical column. The matrix is cured by providing a reinforcement curing apparatus including a steel cylindrical housing split lengthwise into at least two sections, and a plurality of elongated radiant heaters mounted to an interior wall of the housing and oriented to direct their heat inwardly. The curing apparatus is assembled around the perimeter of the column having the reinforcement thereon and operated to heat and cure the reinforcement.

Abstract: An apparatus for reinforcing an external surface of a stationary vertical column with a reinforcing material includes a supply of a reinforcing material and a guide that directs the reinforcing material from the supply onto the stationary vertical column. A winding device moves the guide means in a spiral pattern relative to the stationary vertical column, to wind spiral layers of the reinforcing material onto the vertical column. The winding device is provided as a multipart structure that may be assembled around the vertical column and later disassembled to permit removal from around the vertical column. In one approach, the reinforcing material is tows of a curable composite material that are wound onto the vertical column and later cured in place after the winding device is removed.
