FIELD: building, particularly to erect, renew or reconstruct residential, public and office buildings and building structures. ^ SUBSTANCE: method involves preparing building base, constructing building foundation; erecting or reconstructing building frame or building frame parts, namely columns, girders and floor panels; assembling or disassembling service systems. At least part of building frame to be erected or reconstructed is composite and has grouted column joints. Frame includes girders having composite lower parts, designed to bear technological floor panel end support loads. Lower composite girder part is made as expanded pre-stressed flange, which defines one or two side cantilevered members extending along length thereof after upper monolithic girder part forming. Upper girder part is grouted to lower part thereof along with creation of wall and upper widened flange with one or two mating lower cantilevered members in cross-section. The cantilevered members are fastened to at least one floor panel supported by girder. The composite girder part has 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. ^ 17 cl, 16 dwg |
