Abstract

The invention discloses a device for detecting the bias pressure mechanical properties of an FRP reinforced bamboo integrated wood column and a detection method thereof. The device comprises a detection frame, wherein a placing table for carrying the FRP reinforced bamboo integrated wood column is fixedly installed in the middle of the bottom end of the detection frame, and a moving block is slidably installed at one end of the top of the detection frame. After the detection is completed, people do not need to manually replace the FRP reinforced bamboo integrated wood column, and the operation is convenient. The extrusion force of the extrusion roller on the FRP reinforced bamboo integrated wood column is detected by a pressure sensor, and the distance between the extrusion roller and the FRP reinforced bamboo integrated wood column is detected by a plurality of infrared sensors, so that the bending change of the FRP reinforced bamboo integrated wood column when eccentrically loaded can be detected. At the same time, the position of the extrusion roller can be changed by adjusting the operation of the motor, and the deformation and bearing capacity of the FRP reinforced bamboo integrated wood column can be detected at different positions of the FRP reinforced bamboo integrated wood column, so as to improve the completeness and meticulousness of the detection.
