摘要： Anchor rod having at least one section (4) provided with ribs or other raised portions or profiling and a threaded section (2) at the end or ends. There is a variable transition section (3) between the threaded section (2) and the section (4) provided with raised portions. The anchor rod is produced by using a section of rod material as the starting material and making a thread at at least one end, for example by cutting or by rolling. The section that has to be introduced into the mass to be set, for example concrete, is then produced by deformation, preferably by rolling, the core diameter of that section being reduced, as a result of which the mechanical strength of that section is also appreciably improved.

摘要： In a reinforcing steel that has indentations (4) rolled into a steel rod of approximately circular cross section, the indentations are formed as the reinforcing steel is unwound through circular arcs of different radii set axially symmetrical relative to the indentation. The indentations are rolled into the surface of the rod at a constant depth and have steep flanks. This ensures sufficient bonding despite a lower deformation effort, providing for better ductility parameters. Furthermore, the coiled reinforcing steel has better directivity and improved suitability for welding in the manufacture of welded wire mesh. A process for manufacturing such a reinforcing steel comprises at least two deformation steps.

摘要： With an object of providing a method of working a connection end portion of deformed bar for reinforcing concrete considerably reducing working expense by enhancing easiness of working by promoting mechanical strength of a connection portion by being able to work the connection portion without destructing a steel skeleton structure of a connection portion between pieces of steel bar, deformed bar worked by the method and a connection structure of deformed bar, the invention provides a method of working a connection end portion of deformed bar for reinforcing concrete featured in comprising a swaging step in which in deformed bar for reinforcing concrete featured in swaging at least a connection end portion at normal temperature and forming a rolled thread portion at an outer peripheral face of the connection end portion of the deformed bar subjected to the swaging step in which at least one connection end portion is swaged at a normal temperature such that a maximum diameter of the connection end portion is equal to or slightly larger than a diameter of a cylindrical body of the deformed bar or slightly smaller than a diameter of the deformed bar depending on a degree of working; and a rolling step of forming a thread portion having a diameter substantially equal to a swaging diameter at an outer peripheral face of the connection end portion of the deformed bar which has been subjected to the swaging step.

摘要： These reinforcing steel fibers are mixed with various concretes, and hence steel fibers of the cut wire type as well as a method of fabricating them. A steel fibre has an axial part (1) which has a strength corresponding to a base material at its longitudinal center, nodes (3a, 3b, 3c), in the thickness direction and lateral nodes (2a, 2b, 2c), are formed alternately on both sides of the axial part (1), the nodes (2a, 2b,2c) increase gradually in width towards the ends of the fiber and decrease gradually in thickness, and the nodes (3a, 3b, 3c), project by substantially the same amount over the entire fiber length. These steel fibers are fabricated by the steps of forming fine wires of the desired diameter by roller groups, at least one of which becomes a drive roller in such a manner that four adjacent elongated wire blanks are assembled in one set, continuously applying pressure to the axial part and the nodes at both sides by passing the resultant fine wires through forming rollers with node-machining grooves parallel to the roller shafts at predetermined intervals, and with shallow notches at predetermined intervals on the surface of the roller with node-machining grooves, and cutting the long wires of different shapes obtained from the previous step to the necessary length.
