Description

образца с осью, раст гивающей нагрузку в течение всего времени испытаний.specimen with axle, tensile load during the entire test time.

Поставленна  цель достигаетс  тем, что устройство снабжено герметичным торообразным баллоном, заполненным жидкостью под давлением и располагаемым между кольцевой опорой и зажимами. ,The goal is achieved by the fact that the device is equipped with a pressurized toroid-shaped balloon filled with pressurized fluid and located between the annular support and the clamps. ,

На фиг. 1 и 2 изображено устройство дл  испытани  образцов строительных материалов на раст жение.FIG. Figures 1 and 2 depict a device for testing tensile samples of building materials.

Устройство включает скобообразный захват 1, горизонтальную или наклонную кольцевую опору 2, на которую передаетс  уси .лие от образца 3, герметичный торообразный баллон 4, зажимы 5. К.захвату 1The device includes a clamp-shaped grip 1, a horizontal or inclined annular support 2, to which the force is transferred from sample 3, a sealed toroid-shaped balloon 4, clamps 5. K. gripper 1

прикладывают раст пшающее усилие Р.apply a stitching force R.

Устройство дл  испытани  образца строительных материалов на раст жение работае cheдyющим образом. Образец 3 закрепл ют в зажим 5 и устанавливают на кольцевую опору-2. Между зажимами и кольцевой опорой 2 размешают герметичный торообразный баллов 4, заполненный жидкостью под давлением. Раст гивающа  нагрузка Р с помощью скобообразного захвата 1 передает усилие через кольцевую опору 2, герметичный торообразный блаллон 4 и зажимы 5 на образец. .A device for testing a sample of building materials for tensile work in a cheating manner. Sample 3 is fastened to clamp 5 and mounted on ring support-2. Between the clamps and the annular support 2 stir sealed toroidal points 4, filled with liquid under pressure. The tensile load P with the help of the clamp clamp 1 transfers the force through the annular support 2, the sealed toroid-shaped blonon 4 and the clamps 5 to the sample. .

При небольшом раст гивающем усилии герметичный баллон-тор, заполненный жидкостью под давлением, ведет себ  как плавающа  опора. При этом закрепленный образец в зажимах самоцентрируетс , т.е. геометрическа  и физическа  оси образца совмещаютс  с осью прилагаемой нагрузки в течение всего процесса испытани . В результате приложенна  нагрузка равномерно распредел етс  по сечению образца без применени  каких-либо измерительных приборов и приспособлений.With a small tensile force, a sealed balloon-torus filled with pressurized fluid behaves as a floating support. In this case, the fixed sample is self-centered in the clamps, i.e. The geometrical and physical axes of the sample are aligned with the axis of the applied load during the entire testing process. As a result, the applied load is evenly distributed over the cross section of the sample without the use of any measuring instruments and devices.

Данное устройство дл  испытани  образцов строительных материалов сокращает затраты времени на центрирование более, чем в 5 раз. Точность измерени  фактической прочности на раст жение дл  образцов повышаетс  .на 15-25%. Производительность труда при испытани х образцов строительных материалов на раст жение повышаетс  .в 2-3 раза.This device for testing samples of building materials reduces the time spent on centering by more than 5 times. The measurement accuracy of the actual tensile strength of the samples is increased by 15-25%. Labor productivity in tests of samples of building materials for tensile increase is 2-3 times.

Фор.мула изобретени Formula of invention

Устройство дл  испытани  образцов строительных материалов на раст жение, включающеескобообразный захват,зажимы и кольцевую опору, отличаюшеес   тем, что, с целью самоцентрировани  геометрической и физической осей образца с осью раст гивающей нагрузки в течение всего времени испытаний, оно снабжено герметичным торообразным баллоном, заполненным жидкостью под давлением и расположенным между кольцевой опорой и зажимами, . An apparatus for testing tensile samples of building materials, including a gripping grip, clamps and an annular support, characterized in that, in order to self-center the geometric and physical axes of the sample with the tensile load axis during the entire test period, it is equipped with a sealed toroid-shaped balloon filled with liquid under pressure and located between the annular support and clamps,.
