FIELD: construction.
SUBSTANCE: invention relates to the field of construction, namely to the multi-span frame reinforced concrete building floors reinforcement method. Floor slab reinforcement method is implemented as follows. Placing the tensioned reinforcement is in the building frame spans in the tensile stresses zone, at the floor slab lower edge, and by the supports is at the floor slab upper edge. Then, preliminarily from below and above the floor slab, installing the metal plates and tightening them with studs, with compression force less than the structure concrete prismatic strength. After that, on the lower and upper plates rigidly fastening the stops and placing the tensioned reinforcements ends therein. Then the reinforcement is heated and fixed in the anchors by anchor devices with subsequent tension force transferring through the plates to the structure concrete during cooling.
EFFECT: technical result consists in the labor costs reduction during installation.
