Abstract

A fatigue fracture test device for hydraulic concrete disclosed by the present invention comprises a test bed and a plurality of concrete test pieces, a plurality of hollow partition plates are fixedly installed on the test bed through sealing pieces, the plurality of hollow partition plates jointly define a test area and a contrast area, and the test area and the contrast area are mutually symmetrical. Two supporting plates are vertically arranged on the test bed, a first motor is fixedly installed on one supporting plate, the output end of the first motor is fixedly connected with a driving shaft, the end, away from the first motor, of the driving shaft is rotationally connected with the other supporting plate, and stretching mechanisms are symmetrically arranged at the two ends of the driving shaft. A linkage mechanism is further arranged between the two supporting plates. By arranging the test area and the contrast area, a fatigue fracture experiment can be performed on a plurality of concrete test pieces in the same batch at the same time, so that the influence of each factor on the property change of the concrete test pieces is observed.

Description

technical field [0001] The invention relates to the technical field of concrete testing, in particular to a hydraulic concrete fatigue fracture testing device. Background technique [0002] Concrete is the main basic material in municipal construction, and its internal stress state determines the stability and forming state of building structures. Among them, hydraulic concrete is widely used in water body structures to ensure the structural stability of structures in water bodies. [0003] Due to the complex water environment, before large-scale hydraulic concrete is put into use, the proportion of concrete preparation raw materials needs to be adjusted according to various parameters, and the improved concrete needs to be subjected to fatigue fracture experiments to obtain the stress-strain relationship of concrete materials. In order to ensure the use requirements, in the traditional fatigue fracture test device, only one concrete specimen can be tested at a time, which i...
