Abstract: In this article new technology of concreting of steel reinforce-concrete columns is offered with the use of self-packing concrete, that allows to shorten lab our intensiveness of concreting at erection of monolithic steel reinforce-concrete of vertical constructions. The device of the applied framework system, principle of its work and technology of concreting of steel reinforce-concrete columns, is shown. Description over of equipment is brought for implementation of works by means of the offered method. The technology of work and the advantages of a new technological solution for the construction of monolithic steel-reinforced concrete columns are highlighted. A list over of works and measures, necessary for erection of monolithic columns, is brought. The stages of device of columns are illuminated in detail with the use of this technology and facilities of mechanization. The necessary equipment and special auxiliary means for the production of works are presented. The variants of model cross runners of steel reinforce-concrete columns are given. The analysis of technical and economic indicators is carried out to identify the optimal solution for the construction of steel-reinforced concrete vertical structures of various functional purposes.
Keywords: columns, steel-reinforced concrete structures, rigid external reinforcement, self-sealing concrete, rotary pump.
