A device for fixing concrete resistivity electrode

The utility model provides a device for fixing concrete resistivity electrode, includes the underframe, installs the screw rod frame on the underframe, but install long splint of polylith longitudinal movement and polylith lateral shifting's short splint on the screw rod frame, still install many the clamping nut that are used for promoting long splint and short splint on the screw rod frame, concrete resistivity electrode can be pressed from both sides tightly in the space that short splint and long splint constitute, the utility model discloses can be when the laboratory preparation need the pre -buried concrete sample that establish the electrode, can replace the artifical fixing device that keeps of going on the electrode position. 种用于固定混凝土电阻率电极的装置，包括底框，在底框上安装有螺杆框，在螺杆框上安装有多块可纵向移动长夹板和多块可横向移动的短夹板，在螺杆框上还安装有多颗用来推动长夹板和短夹板的夹紧螺母，混凝土电阻率电极可被夹紧在短夹板和长夹板构成的空间内，本实用新型可以在实验室制备需要预埋设电极的混凝土试件时，可以代替人工对电极位置进行保持的固定装置。
