FIELD: building, particularly to erect, renew or reconstruct residential, public and office buildings and building structures.
SUBSTANCE: in accordance with the first embodiment composite floor panel comprises composite girders connected to columns so that monolithic connection is created. At least one girder has lower part preferably formed as widened composite flange, which defines one or two side cantilevered members extending along length thereof after upper monolithic girder part forming. The cantilevered members are adapted to support ends and/or side faces of floor panel. At least one girder has upper monolithic part including wall and upper widened flange in cross-section. The flange is provided with one or two mating cantilevered members, which are grouted to at least one floor panel supported by the girder. Composite part mounted in floor panel is pre-stressed and preferably made as lower girder flange provided with longitudinal and transversal reinforcing bar projections. Transversal reinforcing bar projections are arranged in at least span girder part and composed of clamps or rod system grouted in lower, composite, girder part during lower girder part forming. Transversal reinforcing bar projection tops are joined to each other by means of at least one reinforcing lattice so that transversal reinforcing bar projections extend above upper parts of floor panels supported by girder at least in connection area between girder and column extending for length of at least 1/3 of girder span.
EFFECT: improved building frame parts cooperation, increased reliability, strength and spatial rigidity of building frame due to building frame forming with the use of composite girder and due to girder, column and floor panel union in single three-dimensional structure during building erection, decreased labor inputs and costs, reduced building erection time and possibility to perform works in winter at negative ambient air temperatures.
