Abstract
A transportable assembly of composite reinforcing sleeves for reinforcing a support column includes a plurality of sleeves defining a discontinuity at lateral edges, wherein each sleeve comprises a plurality of first high tensile strength filaments extending parallel to one another, a plurality of second high tensile strength filaments extending parallel to one another at an angle to the first filaments, and a matrix of fully cured resin in which the first and second filaments are embedded. The sleeves are arranged concentrically and held together by the matrix, with a release film interposed between adjacent sleeves. Each sleeve terminates in edges which are spaced from one another to define a gap in said sleeve, the gaps of said sleeves being in alignment with one another.
Claims5
A reinforcing apparatus comprising:
- a transportable assembly of composite reinforcing sleeves for reinforcing a support column,
- said assembly including a plurality of discrete sleeves each terminating in lateral edges, defining a discontinuity at the lateral edges, and comprising a plurality of first high tensile strength filaments extending parallel to one another, a plurality of second high tensile strength filaments extending parallel to one another at an angle to the first filaments, and a matrix of fully cured resin in which the first and second filaments are embedded;
- each of said sleeves being generally cylindrical, extending through an arc of approximately 360.degree., and defining an inner diameter, an outer diameter and a longitudinal axis, the longitudinal axis dimensions of the sleeves being substantially equal to one another, said sleeves being arranged concentrically, said sleeves including an innermost sleeve having an outer diameter substantially equal to the inner diameter of an adjacent sleeve and an outermost sleeve having an inner diameter substantially equal to the outer diameter of an adjacent sleeve;
- and
- means for holding said sleeves to one another.
