Abstract: A machine and a method for producing uniaxial reinforcing steel bar meshes, in particular for uses with not predominantly static load, has reinforcing wires which are fastened to support strips by individual wire tying.

Abstract: The invention relates to a steel-concrete hollow bodied slab or ceiling comprising concrete webs, which are arranged in between hollow bodies, and a reinforcing layer on top of the hollow bodies and a reinforcing layer underneath the hollow bodies, wherein a hollow body is embodied as a peripherally closed container which is devoid of any ascending force and which is open towards the bottom, whereby ventilation holes are provided in the covering wall thereof and the container comprises spacers. The aim of the invention is to obtain a low-cost hollow bodied slab/ceiling exhibiting good load-bearing behavior and an increased ability to discharge transversal forces according to local requirements. According to the invention, the concrete in at least one concrete web consists of high-tensile fibers and/or at least one steel strut, preferably a double wall anchor, and/or the hollow body which is devoid of ascendant forces has a conical or truncated pyramidal periphery whose uppermost end forms a dome-shaped arch.
