Abstract

The invention provides a high-temperature tensile testing machine which comprises a hand wheel, an adjusting bolt, a pressure sensor, a displacement sensor, an upper connecting rod, a stretching end,a high-temperature resisting adhesive, a fixing end, a lower connecting rod, a high temperature electric heating furnace, a heating element, a temperature measuring element, a temperature control device, a furnace wall, a furnace door, a support frame, a measuring system, a pressurizing frame, a base and a rock sample. The high-temperature tensile testing machine is capable of realizing the tensile strength test for the rock sample under the high temperature condition, is capable of accurately acquiring the tensile strength of the rock sample under high temperature state and has significance in the construction structure safety on the fire scene.

Description

technical field [0001] The invention relates to a tensile testing machine, in particular to the tensile strength test of rock and soil under high temperature. Background technique [0002] The tensile strength of rock and soil is the ultimate ability of rock and soil samples to resist damage under uniaxial tension. Accurately obtaining the tensile strength of rock and soil has important engineering significance. In engineering, it is necessary to carry out laboratory tests to determine the tensile strength of rock and soil according to the actual situation. The tensile strength test of rock and soil is divided into two categories: direct test and indirect test. The indirect test includes axial fracturing test, radial fracturing test and gas splitting test, while the direct test includes uniaxial Shaft tensile test. [0003] The current uniaxial tensile tests are all carried out at room temperature, but the temperature at the fire site is 600-1000°C. The mechanical properti...
