REINFORCED CONCRETE BUILDING ELEMENT Russian patent published in 2020 - IPC E04B1/04 E02D29/12 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to reinforced concrete assembly elements for structures intended for use in capital construction, as elements for assemblage in the place of viewing, rain and transitional wells and chambers (hereinafter – wells), installed on water supply, sewage networks and collectors, transporting sewage, household, storm, production and close to them composition of water. Reinforced-concrete assembly element is used, comprising housing made of reinforcing steel reinforcement and concrete, including at least end surface, as well as bearing working surfaces opposite to it and opposite along its width, at least one of which is equipped with protective lining coating, which is firmly connected to reinforced concrete base of adjacent bearing surface of housing and equipped with reinforcing elements. At that, protective lining is waterproof, in form of solid multilayer laminating coating made of polymer composite materials and including at least primer layer, reinforcing and outer layers laid continuously in layers, where primer layer, conjugated with adjacent surface of housing, is made based on thermosetting polymer binder, reinforcing layer, at least, contains thermosetting polymer binder impregnated reinforcing material based on glass filaments, chopped glass fibers and / or glass mat based thereon, and outer layer in contact with medium is at least made based on thermosetting polymer binder or reinforcing material impregnated with thermosetting polymer binder.

EFFECT: improved operational reliability of the structure due to increased strength of the lining coating, rigidity of the structure of the element and prevention of corrosion of the walls of the reinforced-concrete assembly element under the action of aggressive medium.
