DOUBLE-PIPE-CONCRETE BEAM Russian patent published in 2020 - IPC E04C3/293

Abstract RU 2739271 C1

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to prestressed elements of span structures of small and medium bridges, as well as to construction structural elements of general purpose. Double-pipe-concrete beam contains two pipe-concrete parts consisting of pipe and concrete core, which are rigidly interconnected by grate or wall, differing by that lower concrete core is pre-stressed with fittings or reinforcement cable to allowable limit of concrete compression.

EFFECT: technical result is improvement of bearing capacity of the beam.
