FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used in the construction of pipe-concrete columns of frame buildings. Pipe-concrete column assembly consists of separate elements connected at the welding. Tubular elements of the barrel of the round column are made of cylindrical shell tubes and a concrete core reinforced with a space frame, which in turn is welded to the plates of consoles located in vertical slots of the shells. Concreting of the core using non-shrinkage cement is carried out by a concrete pump from below through an inlet in a shell provided with a concrete gate preventing the flow of the mixture.
EFFECT: technical result consists in increased capacity of the column stem and improved quality of the concreting and reliable inclusion in the joint work with the shell of the reinforced concrete core, and in addition, the labour costs for concreting are reduced.
