Abstract
A sample mounting device for direct tensile test of rock mass is provided, which includes a first positioning stage, a second positioning stage, a first support piece, a second support piece, and a screw drive mechanism. The second positioning stage is arranged above the first positioning stage and capable of moving up and down, and cushion blocks for gluing with the rock mass are coaxially and detachably arranged at opposite ends of the first positioning stage and the second positioning stage, and a rock mass mounting area is formed between the two cushion blocks. A screw of the screw drive mechanism includes a first thread segment and a second thread segment with opposite thread directions. The first support piece is connected with the first thread segment through a nut seat, and the second support piece is connected with the second thread segment through a nut seat.
