METHOD OF ERECTING PREFABRICATED PRESTRESSED REINFORCED CONCRETE FRAMEWORK OF MULTI-SECTION BUILDING

摘要

FIELD: construction.;SUBSTANCE: method of erecting prefabricated prestressed framework includes erecting columns with through openings, laying flooring slabs in the building framework spans and cable reinforcement for the entire length of the building between the slab rows, passed through the column openings, tensioning the reinforcement and anchoring it on the extreme framework columns with the subsequent monolithing joints between the slabs and the columns with concrete. Between the sections of the building, paired columns are erected with forming expansion joints between them. Between the paired columns in the expansion joints, temporary spacers are installed, and anchor devices with thrust plates are installed on the cable reinforcement, and the reinforcement is tensioned with anchoring it, with the abutment on the extreme and paired columns. Then the cable reinforcement in the expansion joints is cut, and the temporary spacers are dismantled.;EFFECT: technology simplification.;7 dwg
