SQUEEZING DEVICE Russian patent published in 1997 - IPC

FIELD: construction of high-pressure reinforced concrete bodies; applicable in reinforcing of body cylindrical part in the process of production of prestressed structure. SUBSTANCE: the essential features of the offered squeezing device consists in that it is provided with a revolving sector plate whose curved surface in working state rests on squeezed structure to ensure shifting and equalizing of stresses in stressed ends and reinforcement. EFFECT: more uniform squeezing of structure over the entire external surface, reduced specific consumption of materials in the structure due to replacement of pilaster by squeezing devices. 5 dwg
