Embodiment

[0044] The quartz glass high-temperature displacement sensor has been applied in the experimental research of the National Natural Science Foundation of China (50278013) chaired by Professor Ding Yining of the Structure Research Institute of Dalian University of Technology. The test simulates a tunnel fire, and a high temperature load is applied to the refractory pipe specimen according to the temperature curve of the Austrian standard (including the temperature rise section and the temperature drop section). In the test, the invented quartz glass high-temperature displacement sensor is used to measure the radial displacement of the component (the test layout is as follows: Figure 8 with Figure 9 shown).

[0045] Since the probe diameter of the LVDT used in the test is 5mm, the quartz glass extension section also uses a rod with a diameter of 5mm. The dimensions of each part of the corresponding connector are as follows: d 1 = 5mm; d 2 = 10mm; d 3 = 8mm; L1 =20mm;L 2 =...

Abstract

The invention belongs to civil engineering test displacement and deformation measurement technique field and is applied in structure element fire analogue situation high temperature displacement and deformation measurement. It is characterized by selection of quartz glass bar with high temperature bearing ability, low heat-conductive parameter, low heat expansion parameters as the extending section of the displacement probe with the connection structure and displacement sensor probe connected together. The extending length minimum value computed according to thermal theory ensures the minimum length to transmit the heat from one end to the other end when one end of the extending contacting the part to be measured.

Description

technical field [0001] The invention belongs to the technical field of displacement and deformation measurement in civil engineering tests, and is applied to the high-temperature displacement and deformation measurement of structural members under simulated fire conditions, and involves the use of non-metallic materials with high temperature resistance, low thermal conductivity, and low thermal expansion coefficient. The method of heat insulation and cooling. Background technique [0002] At present, the direct measurement of the high-temperature displacement and deformation of building structures under simulated fire conditions has always been one of the key issues that plague the research and evaluation of high-temperature performance of structural components and materials. The high-temperature displacement and deformation measurement in the high-temperature performance test of some existing structural components in China generally adopts the indirect measurement method, t...
