Title: Steel concrete pressure vessel for gas or liquid storage - has its rotational wall divided into several segments
Inventor: HERTEL WILHELM DIPL-ING
IPC: E04H7/20
Filed: 1973-10-20
Abstract: The wall is divided into e.g. 5 or 8 segments and after the concrete has set a ring or spiral of stressing steel is placed a round the body so that it is only slightly under stress. If one layer of stressing steel not be sufficient then further layers are applied with the incorporation of spacers.
