COMPOSITE REINFORCEMENT (EMBODIMENTS)

摘要

The invention relates to construction, specifically to composite reinforcements. The composite reinforcement comprises a supporting rod, which is made of a high-strength polymeric material, and a coil with coiled braids and strips of fibres, wherein the relief of the surface of said supporting rod is formed by the coil in one or the other direction, wherein the relief of the surface of the rod is formed by coiled braids and strips of fibres, or by braids or strips of fibres with a multiple-turn winding with different sectional areas and pitches, wherein the pitch of the multiple-turn winding is equal to the sum of the pitches of the different threads of the winding, and the ratio of the sectional areas of the coiled braids to strips is in the range of 1.01 to 250.
