REINFORCEMENT Russian patent published in 1998 - IPC

FIELD: construction engineering. SUBSTANCE: reinforcement of spherical reinforced concrete shells and vessels is originally made in the form of flat net consisting of rings which are combined together by means of connecting members with clearances in joints. This ensures conversion of flat net into part of sphere at extreme extension of rings due to presence of clearances. Value of clearances which satisfies requirements for creating spherical reinforcement must be equal to quotient obtained when difference in lengths of arc created by rings of one row in reinforcement and chord which connects ends of arc is divided by number of clearance in row. Aforesaid arrangement of reinforcement reduces labour-intensity in manufacturing of spherical shells, coverings, and spherical vessels. Their quality is also improved. EFFECT: higher efficiency. 3 dwg
