ARMATURE BUNDLE OF PRESTRESSED REINFORCED CONCRETE STRUCTURE Russian patent published in 2009 - IPC E04G21/12 

FIELD: construction.

SUBSTANCE: suggested invention is related to the field of construction and may be used in manufacturing or erection of prestressed reinforced concrete structures of complex configuration and with high parametres of stresses in stressed armature, also for nuclear power plants. Solution of assigned task makes it possible to increase strength of reinforced concrete structure, comprising mainly armature bundles installed in curvilinear channel. Armature bundle of prestressed reinforced concrete structure comprises multiple armature ropes in protective shell, installed in channel filled with concrete, support plates at the ends of armature bundle for fixation of armature rope ends, device for control of rope stressing force, for control of stressing forces and displacement of control ropes, it is equipped with control ropes of various length, one end of which is fixed in concrete, and the other end with the possibility of free movement is passed through support plate and is connected to device for stressing and control of stressing forces and displacement of specified ropes. Control ropes are not fixed in support plate of armature bundle, do not participate in its stressing, and are used for control of armature bundle stressing forces along its length.

EFFECT: provision of control of stressed-deformed condition of cable along complete length of armature bundle due to determination of various rope areas stressing extent.
