STEEL FIBER BALL FOR REINFORCING CONCRETE AND REINFORCED CONCRETE STRUCTURE HAVING SUCH STEEL FIBER BALL

摘要

PURPOSE: A steel fiber ball for reinforcing concrete and a concrete structure reinforced using the same are provided to uniformly arrange steel fiber in the concrete without the directivity to specific directions. CONSTITUTION: A steel fiber ball(1) for reinforcing concrete is composed of a plurality of longitude-shaped steel fiber(11a, 11b) and equator-shaped steel fiber(12). The longitude-shaped steel fiber includes a zenith point(101a) and a nadir point(101b). The equator-shaped steel fiber crosses the longitude-shaped steel fiber. The steel fiber ball is shaped into a sphere shape. Inner straight fiber(21) is further included in the steel fiber ball.
