silo for compost and the other consisting of prefabricated innestabili in each other

摘要

A set of components for assembly into a compost silo include a plurality of similar, elongated prefabricated parts 1, 2 adapted for interfitting assembly. The parts have grooves 4 in the regions of their ends, these grooves extending at right angles to the length of the parts. The grooves have a width which is slightly larger than the thickness of the material of the prefabricated parts. The depths of each groove is equal to or smaller than one-fourth of the width of the parts 1. Each prefabricated part has at each of its ends an angle part 5 with a free leg 6 extending therefrom.
