REINFORCEMENT FRAME (VERSIONS) Russian patent published in 2012 - IPC E04C5/06 

FIELD: construction.

SUBSTANCE: in a reinforcement frame according to the first version the lateral reinforcement is made of at least one solid reinforcement, deformed to produce alternating ledges and indents of triangular shape and is folded into cylindrical turns of spiral shape with specified diameter and pitch to create helical lines of identical pitch along the entire length of the reinforcement frame on these ledges and indents, where bars of longitudinal reinforcement are fixed at the external sides of the indents, being twisted along the helical lines of the lateral reinforcement indents diameter, according to the second version the lateral reinforcement is made at least from one solid reinforcement, deformed to create alternating ledges and indents of triangular shape and is folded into cylindrical turns of spiral shape with specified diameter and pitch to form helical lines of identical pitch along the entire length of the reinforcement frame on these ledges and indents, to which at the inner sides of ledges there are longitudinal reinforcement bars fixed, being twisted along helical lines of lateral reinforcement ledges diameter, according to the third version, the lateral reinforcement is made from at least one solid reinforcement, deformed to produce alternating ledges and indents of triangular shape and folded into cylindrical turns of spiral form of the specified diameter and pitch with formation of helical lines of identical pitch along the entire length of the reinforcement frame on these ledges and indents, where longitudinal reinforcement bars are fixed at the inner sides of ledges, being twisted along helical lines of lateral reinforcement ledges diameter, and at the outer sides of indents there are rods of longitudinal reinforcement fixed, being twisted along helical lines of lateral reinforcement indents diameter.

EFFECT: simplified design, higher resistance to transverse and longitudinal external forces.
