Description
(54) ПРИБОР ДЛЯ ОПРЕДЕЛЕНМ ПРОЧНОСТИ БЕТОНА(54) DEVICE FOR CONCRETE STRENGTH DETERMINED
1one
Изобретение относитс к испытательной технике, а именно, к молоткам дл определени прочности строительных материалов, например бетона.The invention relates to testing equipment, namely, hammers to determine the strength of building materials, such as concrete.
Наиболее близким к предлагаемому . по технической сущности и достигаемому эффекту вл етс прибор дл определени прочности бетона, содержащий корпус в виде стакана, индентор, закрепленный под его днищем, измерительньй .узел в виде стержн , размещенного внутри стакана с возможностью перемещени вдоль его оси, и руко тку , жестко закрепленную на корпусе l.Closest to the proposed. the technical essence and the achieved effect is a device for determining the strength of concrete, comprising a housing in the form of a glass, an indenter attached under its bottom, a measuring node in the form of a rod placed inside the glass with the ability to move along its axis, and a handle rigidly fixed on the case l.
Однако при испытани х бетона данным прибором наблюдаютс значительные затраты времени, так как после каждого удара необходимо измер ть выпет стержн и возвращать его в исходное положение, при э-том нужно вычисл ть суммарную силу удара путем сложени отдельных величин вылета стержн .However, during tests of concrete with this device, a considerable amount of time is observed, since after each impact it is necessary to measure the rod and pull it back to its original position, and at that it is necessary to calculate the total force of the impact by adding the individual outreach values of the rod.
Цель изобретени - повьппение производительности испытаний.The purpose of the invention is to test performance.
Поставленна цель достигаетс тем, что стержень выполнен в виде посто нного магнита.The goal is achieved by the fact that the rod is made in the form of a permanent magnet.
На чертеже представлена схема прибора.The drawing shows a diagram of the device.
Прибор содержит корпус 1, индентор 2, стержень 3 в виде посто нного магнита и руко -псу 4.The device includes a housing 1, an indenter 2, a rod 3 in the form of a permanent magnet and a handle-4.
10ten
Прибор работает следующим образом.The device works as follows.
Перед проведением испытаний стержень 3 устанавливают в пазу 5 в крайнее верхнее положение и нанос т п ть ударов по образцу. Под воздей-. Before testing, the rod 3 is installed in the groove 5 to the extreme upper position and five strokes are applied to the sample. Under the influence of
