An one-time casting pattern from hydrocarbon polymers is assembled in a spatial piled structure from gratings with identical cells in the form of holes in a framing of six partitions of the same length, wherein the gratings are secured in each corner of the cells by in parallel located cross-pieces of equal length, so that each point of attachment comprises three partitions and one cross-piece. The pattern is characterized in that all partitions and cross-pieces at the junction are located at an angle of 109,47° therebetween. |
