Stand for testing of structures under axial and eccentric ANNEX alternating loads

摘要

The invention relates to construction, namely, to the determination of physical and mechanical properties of building products, preferably concrete prisms, and can be used to study the strength properties of solid materials by applying an axial and off-center of tensile and compressive static alternating loads without moving the sample on a test bench . The object of the utility model is an extension of the functionality of the test set, which has the possibility to carry out tests on samples, and tensile and compressive on one stand without moving the sample. The problem is solved in that the proposed solution stand is further provided with at least two movable platforms power, and the drive is designed as a single-acting device, the reverse holds on stand device, power device and the adjustment mechanism. In addition, single-acting device is designed as a single-acting hydraulic jack. In addition, reverse is designed to change the direction of stresses on the test sample and is in the form of movable platforms and force the guide rods, which are installed on movable platform power movably. Furthermore, power is designed to create a load set value and a predetermined loading rate, and configured as a movable force platform which is mounted on the guide rods to be movable, and a hydraulic ram single-acting, which is arranged to contact exposure with a movable force platform. Furthermore, the adjusting mechanism for adjusting the displacement force platforms, changes the direction of load and is in the form of guide rods and stoppers which are mounted on the guide rods and form therewith a pair of screw. 1 NC n. f BACKGROUND ZP 4 f ly-2 Fig.
