Изобретение относитс к измерительной технике и может быть использовано дл определени напр женно-деформированного состо ни изгибаемых железобетонных элементов.The invention relates to a measurement technique and can be used to determine the stress-strain state of bending reinforced concrete elements.
Цель изобретени - повышение точности за счет измерени поворота опорных сечений.The purpose of the invention is to improve the accuracy by measuring the rotation of the support sections.
На чертеже представлена схема реализации способа на примере железобетонной балки пр моугольного сечени .The drawing shows a scheme for implementing the method by the example of a reinforced concrete beam of rectangular cross section.
Способ осуществл ют следующим образом .The method is carried out as follows.
На наружной поверхности 1 балки высотой h, шириной b и длиной I размещают реперные точки 2-4 на условно проведенной линии 5 на уровне нейтральной оси балки, размещают в опорных сечени х реперные точки 6, 7 и 8, 9 на уровне прохождени продольных стержней 10 и 11 раст нутой и сжатой арматуры. С помощью реперных точек 2, 3 и 4 определ ютOn the outer surface 1 of the beam with height h, width b and length I, the reference points 2-4 are placed on the conventionally drawn line 5 at the level of the neutral axis of the beam, and the reference points 6, 7 and 8, 9 at the level of the passage of the longitudinal rods 10 are placed in the reference sections. and 11 expanded and compressed reinforcement. With the help of reference points 2, 3 and 4 determine
стрелу прогиба до и после деформировани , а с помощью реперных точек 6-9 измер ют углы поворота опорных сечений балки. С учетом полученных значений по известным зависимост м определ ют напр женно-деформированное состо ние железобетонных элементов.the deflection arrow before and after deformation, and with the help of reference points 6–9, the angles of rotation of the support sections of the beam are measured. Taking into account the obtained values, the stress-strain state of reinforced concrete elements is determined by known dependencies.
Ф ормула изобретени Способ определени напр женно-деформированного состо ни изгибаемых железобетонных элементов, заключающийс в том, что измер ют стрелу прогиба относи- тельно нейтральной оси элемента до и после деформировани и определ ют напр женно-деформированное состо ние, отличающийс тем, что, с целью повышени точности, измер ют поворот опорных сечений относительно точек, расположенных на наружной поверхности изгибаемого элемента на уровне прохождени продольных осей раст нутой и сжатой арматуры.Formula of the invention A method for determining the stress-strain state of bending reinforced concrete elements, which consists in measuring the deflection boom relative to the neutral axis of the element before and after the strain, and determining the stress-strain state, characterized in that In order to increase accuracy, the rotation of the support sections relative to points located on the outer surface of the bending element at the level of the longitudinal axes of the extended and compressed reinforcement is measured.
