Definitions

  • This invention relates to reinforcing elements for concrete.
  • a main object of the invention is to provide a concrete reinforcing element whereby an eflicient anchorage in the concrete is obtained and which, moreover, enables the reinforcements to be easily assembled with excellent rigidity. It will be observed that the elements are assembled without welding, which makes it possible to use steel of high mechanical resistance obtained by thermal treatment, which resistance would be destroyed by welding.
  • reinforcing elements are generally made of iron or steel, it will be understood that the use of other metals, as well as plastic, glass and other materials, is within the scope of the invention.
  • reinforced concrete includes a reinforcing element of which at least a portion is twisted into a spiral.
  • FIG. 1 is a view showing the assembly of two reinforcing elements of the invention
  • FIG. 2 is a section along the line IIII of FIG. 1;
  • FIG. 3 is a section along the line III-III of FIG. 1;
  • FIG. 4 is a view showing the assembly of two elements of the invention forming a branch
  • FIG. 5 is a schematic view showing the formation of a pulling loop on a reinforcing element of the invention.
  • FIG. 6 is a schematic view showing the fixing of two intersecting elements by means of a third element of the invention.
  • the reinforcing element of the invention is a round rod 1 twisted into a spiral in such a manner that the axis of the spiral, the locus of which is represented in FIG. 2 at 0, remains Within the rod 1.
  • This type of spiral element moreover ensures a fastening in the concrete which is greatly superior to that obtained with known notched steel elements.
  • a pulling loop 4 (FIG. 5) can be formed by bending back on itself an element 1c and overlapping the spiral of the bent back portion with that of the remainder of the element.
  • the twisted spiral element of the invention enables composite structures and joins to be easily formed and these can, moreover, be reinforced by a coating of abrasive powder, by knurling the elements, or by producing friction by means of other spiral elements which preferably have a smaller thread than those of the assembled elements.
  • the invention is not limited to the embodiments described and shown, but covers all variants thereof.
  • the elements can have any form, such as semicircular, elliptical, square, etc.
  • Preformed reinforcing elements for reinforced concrete comprising an elongated rod preformed into a helix having a constant pitch, a constant helix angle with respect to the longitudinal center line, and a constant diameter for the convolutions making up the helix, said rod, in the relaxed state, having the locus of the axis of the helix within the reinforcing rod periphery, a second elon gated helical rod having helix characteristics identical to the first said rod, the respective helixes of the two rods being intertwined along portions of the two rods, thereby joining said two rods along said portions, each of said rods along said joined portions having its respective locus of the axis of the helix exterior of the rod periphery, the diameter of the convolutions being slightly increased and expanded along said joined portions so that the re siliency of the two helical rods cause the rods to grip one another, whereby the two preformed elements may be spliced to one another at any location
