Изобретение относитс к области исследовани физико-механических свойств строительных материалов.The invention relates to the field of studying the physicomechanical properties of building materials.
Известно устройство дл испытани образца строительного материала на сжатие, включающее опорную плиту пресса со сферическим шарниром.A device for testing a compressive sample of a building material is known, which includes a press base plate with a spherical hinge.
Цель изобретени - повышение степени точности определени за счет улучшени центрировани образца.The purpose of the invention is to increase the degree of accuracy of the determination by improving the centering of the sample.
Достигаетс это тем, что устройство выполнено с нромежуточным сферическим шарпиро .м.This is achieved by the fact that the device is made with an intermediate spherical Shapiro.
Изобретение по сн етс чертежом.The invention is illustrated in the drawing.
Устройство содержит опорную плиту 1 пресса с шаровой опорой скольжени и сферический шарнир 2.The device comprises a base plate 1 of the press with a ball bearing slide and a spherical hinge 2.
Между опорной плитой и сферическим шарниром установлен промежуточный сферический шарнир 3.Between the base plate and the spherical hinge is installed intermediate spherical hinge 3.
Таким образом смещаютс два шарнира с радиусами шаровой поверхности п и Гг, центры которых лежат над плоскостью опорной плиты на рассто ни х /ii и /i2. Это позвол ет испытывать образцы высотой hi и hz (и близких к ним размерами). Дл .возвращени Thus, two hinges are displaced with the radii of the spherical surface n and Gg, the centers of which lie above the plane of the base plate at a distance x / ii and / i2. This allows samples to be tested in heights hi and hz (and sizes close to them). For return
промежуточного сферического шарнира в исходное положение между ни.м и плитой могут быть помещены пружины 4 необходимой жесткости .intermediate spherical hinge to its original position between the N. m and the plate can be placed spring 4 required stiffness.
Принцип действи такого устройства основан на том, что при испытании образца определенных размеров из всех шарниров будет работать тот, центр вращени которого располагаетс ближе всего к верхней грани образца .The principle of operation of such a device is based on the fact that when testing a sample of a certain size from all the hinges, the one whose center of rotation is located closest to the upper face of the sample will work.
С помощью машин, оборудованных описанным устройством, можно повысить точность испытани образцов различных размеров и получить заметную экономию строительных материалов, котора достигает, как показывают опыты, 5-1(1%.With the help of machines equipped with the described device, it is possible to improve the accuracy of testing samples of various sizes and to obtain noticeable savings in building materials, which, as experience shows, reach 5-1 (1%.
