NET VAULT Russian patent published in 2013 - IPC E04B1/32 

FIELD: construction.

SUBSTANCE: net vault comprises connected longitudinal elements and elements transverse to the longitudinal axis of the vault. Elements create a net with rectangular cells along the cylindrical surface of the vault. Transverse elements are arranged in a staggered order to form split arcs along the vault arch. Transverse elements are made of a bar of rectangular cross section and are connected at the ends and in the centre with adjacent longitudinal elements. Each of the specified types of connection unit is arranged in a staggered order. Longitudinal elements are made as continuous of double-tee or channel cross section. Ends of transverse elements are joined with the longitudinal element in one level. In the unit of connection in the centre of transverse elements the longitudinal and transverse elements are arranged floor by floor. Ends of transverse elements are chamfered as capable of coupling with the wall and shelves of the double-tee or the channel.

EFFECT: increased rigidity and reduced labour intensiveness of vault manufacturing and assembly.
