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.
Claims15
A method for preparing a reinforced column, comprising the steps of:
- providing a vertically extending column having a column effective diameter;
- positioning a reinforcement to contact a perimeter of the column, the reinforcement comprising elongated fibers in a curable matrix;
- providing a reinforcement curing apparatus comprising
- 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;
- assembling the curing apparatus around the perimeter of the column having the reinforcement thereon;
- and
- operating the radiant heaters to heat and cure the reinforcement.
