Abstract (en)
[origin: WO2013054006A1] According to the device of the invention, in order to counter the consecutive disturbances in the disaggregation of the concrete due to Poisson's ratio, the compressed bars are banded by a continuous piece of steel wound into coils (3) that are connected via straight segments (2). The ladders (1), which constitute the basic three-dimensional structural elements, have simple triangular, rectangular, or polygonal cross-sections. Said basic units can be assembled either by bars or, in order to increase the ultimate strength, by ladders (5) having axes that intersect the mid-plane.
