FIELD: construction industry. ^ SUBSTANCE: there proposed are versions of monolithic reinforced concrete plate which consists of concrete body and reinforcement, and has through slinging holes. Each hole is formed with the slinging element located in concrete mass and having in its housing the upper inlet channel with passage cross section enough for the lifting slinging device to be moved therethrough, lower outlet channel connected to lower external surface of concrete body, and widening in the middle part so that there formed around the inlet channel is internal cavity having in its upper part the surface enough to be attached to supporting elements of the lifting slinging device. At that, slinging element is equipped with reinforcing elements. Besides versions of manufacturing monolithic reinforced concrete plate are proposed. ^ EFFECT: increasing plate strength in compliance with its operating conditions. ^ 37 cl, 10 dwg |
