Filler body for reinforcing e.g. concrete, has three circular or ellipsoid loops of wires arranged around axes, and loose-fit cladding form applied around body, so that body forms spherical or ellipsoid body

摘要

The body has three loops of wires (A, B, C), which are circular or ellipsoid. The loops are arranged around axes (A1, A2). A loose-fit cladding form is applied around the body, so that the body forms spherical or ellipsoid body. The wires are provided with corrugated structured surface. The wires are continuously bent to an endless spiral form. The body is produced from sheet metal piece by pressing and deforming.
