PRESTRESSED REINFORCED CONCRETE STRUCTURE Russian patent published in 2006 - IPC E04B1/06 

FIELD: building, particularly structures consisting primarily of prestressed load-supporting, block-shaped or slab-shaped elements.

SUBSTANCE: structure comprises stretched areas prestressed from both ends thereof. The structure is provided with concrete cleat wedges arranged transversely to highly stretched areas in maximal possible proximity to area of maximal stretching force application. The concrete cleat wedges are fixedly secured to transversal prestressed reinforcement members, preferably singular ones supported by compressed area of prestressed reinforced concrete structure through inner end anchors releasably connected to transversal reinforcement members when concrete cleat wedges abut inner through free travel slots of minimized depth, namely when inclined surfaces of concrete cleat wedges, which squeeze highly stretched areas of prestressed reinforced concrete structure, with inclined concrete surfaces are arranged in inner through free travel slots and in outer surfaces of highly stretched areas without wedge sticking.

EFFECT: reduced metal consumption, increased service life and reduced stresses.
