Description
Известен прибор дл определени прочности образцов строительных материалов, например каменных, раскалыванием, включающий унругую скобу с раскалывающими элементами и силовозбудитель.A device is known for determining the strength of samples of building materials, for example, stone, by splitting, which includes a uniform bracket with splitting elements and an energizer.
Цель изобретени - обеспечить возможность проведени испытани в полевых услови х .The purpose of the invention is to provide an opportunity for field testing.
Достигаетс это тем, что силовозбудитель выполнен в виде винтового домкрата и смонтирован на одном из концов упругой скобы.This is achieved by the fact that the exciter is made in the form of a screw jack and mounted on one of the ends of the elastic bracket.
На чертеже изображен предлагаемый прибор .The drawing shows the proposed device.
Прибор имеет упругую скобу /, имеющую раскалывающие элементы 2.The device has an elastic bracket / with splitting elements 2.
Силовозбудитель прибора выполнен в виде винтового домкрата 3, который смонтирован на одном из концов унругой скобы.The actuator of the device is made in the form of a screw jack 3, which is mounted on one of the ends of the universal bracket.
Прибор снабжен кронштейнами 4 дл закреплени индикатора 5 часового типа и регулировочным винтом 6.The device is equipped with brackets 4 for fixing the indicator of 5 hour type and an adjusting screw 6.
Испытуемый образец устанавливаетс между раскалывающими стержн ми 2. Поворачиваетс руко тка, и через винтовой домкрат 3 поступательное движение передаетс верхней опорной площадке 7. Она движетс до соприкосновени раскалывающих стержней 2 с образцом . При дальнейшем закручивании руко тки 8 скоба начинает упруго разгибатьс , а на образец передаетс через раскалывающие стержни сила, вызванна внутренними усили ми в скобе и пропорциональна ее деформаци м . Деформации вызывают перемещение концов скобы, которые регистрируютс индикатором часового типа и выражают в определенно .м масштабе величину усили , действующего на образец. Перед испытанием регулировочным винтом 6 ндикатор 5 устанавливаетс в нулевое положение и по перемещени м концов скобы с помощью индикатора определ ют раскалывающие усили , которые пропорциональны перемещени м.The test specimen is installed between the splitting rods 2. The handle is turned, and through the screw jack 3, the forward movement is transmitted to the upper support platform 7. It moves until the splitting rods 2 come into contact with the sample. Upon further twisting of the handle 8, the bracket begins to elastically bend, and the force transmitted by the splitting rods to the sample is caused by internal forces in the bracket and is proportional to its deformation m. The deformations cause the movement of the ends of the staples, which are recorded by a watch-type indicator and express on a definite scale the magnitude of the force acting on the sample. Prior to testing by the adjusting screw 6, the indicator 5 is set to zero position and, by moving the ends of the clevis, using the indicator determine the splitting forces, which are proportional to the movements.
