FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in making lightweight wall products. Method of producing hollow-core concrete block includes laying into mould, with its preset size, longitudinal reinforcement in the form of manufactured continuous tubular frame with horizontal arrangement of polymer-composite tubes. For this, first, cutting the required number of longitudinal polymer-composite tubes with a length equal to the length of the mould, and transverse polymer-composite tubes with a length equal to the width of the mould, as well as polymer composite posts equal to the height of the block, which are fastened together, or using vertical arrangement of tubes, which are installed and fastened in two horizontally located grids along the entire length and width of the mould. Then the mould is filled with the concrete mixture, compacted, maintained for gaining the required strength so that after hardening the hollow tubular concrete mass is obtained in the form of a semi-finished product. Formwork is removed. Thereafter, it is cut into blocks of preset size and shape.

EFFECT: simplification of manufacturing technology and reduction of labour intensity, reduction of material consumption, which increases efficiency of production of hollow-core concrete blocks as a whole.
