PRESTRESSED REINFORCED CONCRETE SLAB OF PREFABRICATED AERODROME OR ROAD SURFACE REINFORCED WITH HIGH-STRENGTH STRESSED REINFORCEMENT

摘要

FIELD: construction.;SUBSTANCE: in the proposed solution each rod of stressed high-strength reinforcement prior to stressing is pressed with traditional temporary external anchors and additional inner anchors arranged in a concrete body in close proximity to a slab edge. Availability of internal pressing anchors provides for additional fixation of stressed reinforcement in a concrete body after cutting of its external protrusions and prevents formation of radial cracks in concrete and slipping of stressed reinforcement relative to concrete at the moment of pre-stressing forces transfer from reinforcement to concrete.;EFFECT: creation of efficient structure of a prestressed reinforced concrete slab of a prefabricated aerodrome or road surface reinforced with high-strength stressed reinforcement and reduction of reinforcement consumption and slab cost.;3 cl, 3 dwg
