Description

..

Изобретение относитс  к области армировани  строительных конструкций из усадочных бетонов с предварительно напр жеппой арматурой.The invention relates to the field of reinforcement of building structures of shrinkable concrete with pre-tension reinforcement.

Известен стержень арматуры дл  строительных конструкций из бетона, имеющий на поверхности выступы, расположенные по винтовой линии .A reinforcement bar for building structures made of concrete is known, having protrusions located on a surface along a helical line.

Известен также стержень арматуры дл  строительных конструкций из бетона с предварительно напр женной арматурой, размещенной в теле бетонного монолита, имеющий на поверхности выступы, расположенные по винтовой линии .Also known is a rebar for building structures made of concrete with prestressed reinforcement placed in the body of a concrete monolith, having protrusions on the surface located along a helical line.

Известные стержни арматуры, размещенные в теле бетонного монолита, не обеспечивают снижени  напр жений сжати  в арматуре и напр жений раст жени  в бетоне в период его твердени .The known reinforcement bars placed in the body of a concrete monolith do not provide a decrease in compressive stresses in the reinforcement and tensile stresses in the concrete during its hardening.

Дл  снижени  напр жений сжати  в стержне арматуры и напр жений раст жени  в бетоне в период его твердени  в предлагаемом стержне выступы на поверхности стержн  арматуры выполнены в виде гребн  с уступом 8 и конической поверхностью, имеющей уклон к продольной оси стержн  арматуры в сторону , противоположную действию сжимающего усили  от усадки бетона в иериод его твердени .To reduce compressive stresses in the reinforcement bar and tensile stresses in concrete during its hardening in the proposed rod, the protrusions on the surface of the reinforcement rod are made in the form of a ridge with a ledge 8 and a conical surface that has a slope to the opposite direction of the reinforcing rod. compressive force from shrinkage of the concrete in the period of its hardening.

На фиг. I изображен предлагаемый стержень арматуры, общий вид; на фиг. 2 - то же, разрез; на фиг. 3 - стержень арматуры в теле бетонного монолита.FIG. I shows the proposed reinforcement bar, general view; in fig. 2 - the same section; in fig. 3 - rod reinforcement in the body of a concrete monolith.

В процессе затвердевани  бетона возникают усадочные напр жени , перемещающие массу бетона вдоль стержн  арматуры. Конические поверхности имеющие уклон к продольной оси стержн  арматуры в сторону, противоположную действию сл имающего усили , обеспечивают возможность перемещени  массы бетона вдоль стержн  арматуры в период твердени  бетона, а уступы преп тствуют удлиненпю массы бетона после его затвердевани .In the process of hardening of concrete, shrinkage stresses occur, moving the mass of concrete along the reinforcement rod. Conical surfaces with a slope to the longitudinal axis of the reinforcement bar in the direction opposite to the effect of the applying force provide the possibility of moving the mass of concrete along the reinforcement rod during the hardening of the concrete, and the ledges prevent the elongated mass of concrete after it has hardened.
