Description

Известны способы исследовани  коррозии арматуры железобетона или армоцемента в напр женном ее состо нии, состо щие в том, что испытуемые образцы нагружают сложными специальными приборами, снабженными рычажной системой с грузами и т. п.Methods are known for investigating the corrosion of reinforcement of reinforced concrete or reinforced cement in its stressed state, such that the test samples are loaded with complex special devices equipped with a lever system with weights, etc.

Предложен новый способ, который упрощает исследовани  за счет использовани  образцов в виде железобетонных или армоцементных колец с внутренней конической поверхностью.A new method has been proposed that simplifies research by using samples in the form of reinforced concrete or reinforced cement rings with an inner conical surface.

Эти образцы снабжены, коническими железобетонными сердечниками . Создание и поддержание напр жени  в арматуре образцов достигаетс  за счет вдавливани  сердечников в кольцеобразные образцы.These samples are equipped with conical reinforced concrete cores. The creation and maintenance of stress in the armature of the samples is achieved by pressing the cores into the ring-shaped samples.

Обеспечение точного контакта конических поверхностей кольца li сердечника достигаетс  тем, что при бетонировании кольца предварительно изготовленный сердечник закладываетс  в форму и служит «внутренней опалубкой кольца. Таким образом, отверстие кольца формируетс  по конической поверхности сердечника, который остаетс  в кольце. Во избежание сцеплени  сердечника с кольцо.м поверхность сердечника перед бетонированием кольца смазываетс  тонким слоем солидола .Ensuring accurate contact of the conical surfaces of the core ring li of the core is achieved by the fact that when the ring is concreted, a prefabricated core is laid into the mold and serves as the "internal ring formwork. Thus, the opening of the ring is formed along the conical surface of the core that remains in the ring. In order to prevent the core from adhering to the ring, the surface of the core is lubricated with a thin layer of grease before concreting the ring.

При истечении срока твердени  образца в заданных температуровлажностных услови х производитс  нагружение железобетонного ил1 армоцементного кольца. С этой целью железобетонный конический сердечник вжимаетс  при помощи пресса в отверстие кольца. В кольце по вл ютс  раст гивающие напр жени , а при дальнейшем продвижении сердечника возникают трещины различного раскрыти . В любой момент -продвижение сердечника может быть остановлено и благодар  самоторможению конуса зафиксирована желаема  достигнута  деформаци  кольца. После этого испытуемый образец помещаетс  в заданную среду дл  коррозионных испытаний на сколь угодно длительные сроки.At the expiration of the sample hardening period in the given temperature and humidity conditions, the reinforced concrete or armature cement ring is loaded. To this end, the reinforced concrete conical core is pressed into the opening of the ring with a press. Tensile stresses appear in the ring, and as the core advances further, cracks of various openings appear. At any time, the advancement of the core can be stopped and, due to the self-retarding of the cone, the desired deformation of the ring is achieved. Thereafter, the test specimen is placed in a predetermined corrosion test environment for an arbitrarily long time.

Предложенный способ создани  напр женного состо ни  арматуры и образовани  трещин в железобетонных или армоцементных образцах значительно ускор ет, упрощает и удешевл ет технологию подготовки образцов дл  коррозионных испытаний и устран ет необходимость в сложных специальныХ нагрузочных устройствах.The proposed method of creating a stressed state of reinforcement and the formation of cracks in reinforced concrete or reinforced cement samples significantly speeds up, simplifies and cheapens the technology for preparing samples for corrosion tests and eliminates the need for complex special load devices.
