Abstract
1. Способ определения прочности бетона методом скалывания ребра, путем крепления прибора с заданием направления приложения нагрузки к скалывающему элементу под углом к поверхности участка измерения, приложения нагрузки от силового цилиндра к скалывающему элементу с заданной скоростью до момента скола ребра, фиксирования величины скалывающего усилил и расчетного определения прочности бетона, отличающийся тем, что крепление прибора осуществляют крепежным элементом в предварительно подготовленном отверстии на одной грани, а нагрузку прикладывают к смежной грани углового участка. ! 2. Способ определения прочности бетона методом скалывания ребра, путем крепления прибора с заданием направления приложения нагрузки к скалывающему элементу под углом к поверхности участка измерения, приложения нагрузки от силового цилиндра к скалывающему элементу с заданной скоростью до момента скола ребра, фиксирования величины скалывающего усилия и расчетного определения прочности бетона, отличающийся тем, что усилие от силового цилиндра прикладывают непосредственно к скалывающему элементу, при этом заданное направление приложения нагрузки совмещено с осью силового цилиндра. 1. The method of determining the strength of concrete by cleaving the ribs, by fixing the device with the direction of application of the load to the cleaving element at an angle to the surface of the measurement site, applying the load from the power cylinder to the cleaving element at a given speed until the edge is cleaved, fixing the value of cleaving reinforced and calculated determining the strength of concrete, characterized in that the fastening of the device is carried out by a fastening element in a pre-prepared hole on one face, and the load Apply to the adjacent face of the corner section. ! 2. A method for determining the strength of concrete by cleaving a rib by fixing the device with the direction of load application to the shear element at an angle to the surface of the measurement site, applying load from the power cylinder to the shear element at a given speed until the edge is cleaved, fixing the shearing force and the calculated determining the strength of concrete, characterized in that the force from the power cylinder is applied directly to the shearing element, while the specified direction is applied I load combined with the axis of the cylinder.
