STRUCTURAL SYSTEM OF MULTISTORY BUILDING AND PROCESS OF ITS ERECTION ( VARIANTS ) Russian patent published in 2003 - IPC

FIELD: construction industry, construction of multistory civilian buildings. SUBSTANCE: structural system of multistory building includes precast reinforced concrete building frame formed by columns with breaks of concrete and baring of their working reinforcement, by plates above columns with through holes for passage of columns and butt-joining to them, by plates-inserts resting with edges against cantilevers of plates above columns and interjoining, by partitions and self-bearing walls. Internal faces of through holes in plates are inclined towards columns, pyramidal wedge is made in each break of monolithic concrete of column, is directed upwards with its narrow part and tightly fits inclined faces of through holes in plates above columns with side faces. Plates above columns are fitted with upper working reinforcement concentrated in the form of groups ( bundles ) directly along faces of through holes. Columns of extreme row are made fast to plates-inserts with the aid of monolithic cross-bars passed through breaks in concrete in extreme columns over entire length of building. Outer walls are born against each floor. Columns of outer row are located in the thick of outer walls. Process of erection of multistory building ( variants ) includes mounting of columns, installation of assembling attachments in the form of tower supporting facilities, assembly of floor slabs, making them monolithic with columns and with adjacent slabs, dismantling and rearrangement of attachments on finished floor and arrangement of outer walls and partitions. In correspondence with first variant floor slabs are laid in two phases and outer walls are assembled after arrangement of floor. According to second variant outer walls are arranged simultaneously with supporting facility with bearing of its members against tower supporting facilities and outer wall. EFFECT: reduced usage of metal and energy in process of erection. 9 cl, 15 dwg
