Fixing device for material performance test piece of small wood structure test piece for zero (micro) damage detection

Abstract

The invention discloses a fixing device for a material performance test piece of a small wood structure test piece for zero (micro) damage detection. The device is mainly composed of a fixing device support, a fixing device base, a base fixing bolt, a fixing device support retracting device, a support angle universal wheel, a fixing device support and a fixing device support clamping point. The invention discloses a scanning data acquisition fixing device which is used for detecting the performance of a material by using a stress detection method, a relative resistance value detection method or small test piece surface damage when a small test piece of a wood structure is subjected to zero (micro) damage detection. The fixing device can be adjusted according to different heights, widths and the like of the small test pieces to meet the supporting requirements of the small test pieces of different test tables, and meanwhile, the fixing device support and a base can be respectively controlled to adjust in different directions to meet the data acquisition of the small test pieces in the supporting process. The end modes of the support of the convertible fixing device meet the requirement of 360-degree rotation of the test piece for multi-directional data acquisition, operation is easy, acquisition of various zero (micro) loss detection data is met, and the detection efficiency isimproved.

Description

technical field [0001] The invention relates to a test piece fixing device for non-(micro) damage testing of the material properties of small wooden test pieces. The invention belongs to the technical field of traditional building protection. Background technique [0002] Wooden components occupy an important position in ancient buildings. Traditional wooden component material performance testing mostly uses destructive tests to obtain data, which takes a long time to detect and destroys wooden components. The use of stress method or impedance method and other non-(micro) damage detection can make wooden components in no (micro) damage, and use small specimens to perform scale-down material performance testing. , bending resistance and other performance research is conducive to the protection of ancient buildings. [0003] The stable placement of the specimen directly affects the test results when performing non-(micro)destructive testing on the material properties of smal...

This seriously affects the accuracy of data collection, and at the same time increases the workload and intensity of data collection

[0004] Aiming at the problem that the test pieces cannot be fixed during the current non-(micro)destructive testing of the material properties of small wooden test pieces, the present invention proposes a test piece fixing device for non-(micro)destructive testing of the material properties of small wooden test pieces. Use the fixed base to effectively fix the specimen fixing device on the test bench, and then select and adjust different support ends and the rotation direction of the support according to the selected non-destructive (micro) detection method, and make the experiment according to different clamping orientations. The measurement of the specimen is more stable, suitable for non-(micro) damage detection such as stress method, impedance method and other non-(micro) damage detection, as well as 360° data collection on the surface of the specimen by the scanner, providing data support for the performance test of wooden materials, and also Improve the efficiency and standardization of data collection by inspectors
