BEARING STRUCTURE OF MULTISTOREY BUILDING STRUCTURE (VERSIONS) AND METHOD OF ERECTION OF MULTISTOREY LONG SPAN STRUCTURE

摘要

FIELD: construction.;SUBSTANCE: invention relates to construction, particularly, to the bearing structure of the multistorey long span structure. Bearing frame consists of one or more two-storey bearing tiers, series-arranged one above the other as to height of the structure. On the top floor of the two-story bearing tier the bearing long span inter-floor metal structures in the form of flat combined truss systems are arranged, and at the level of the ground floor of the two-story bearing tier at the edges of spans in truss systems plane the vertical communications with a height of a floor, connected with assemblies of truss systems are performed. Upper and lower belts of truss systems are composed of the belt trusses or the belt beams, at the level of which there are inter-spanning trusses or crosswise direction beams. Reinforced-concrete inter-floorings are arranged along the upper level of the belt trusses or the beams. Other versions of bearing structures and method of their erection are suggested.;EFFECT: technical result of the invention consists in increase of free space of the structure.;4 cl, 11 dwg
