Specific embodiment
As shown in figure 1, a kind of concrete compression-resistanmodifier experimental rig, including rack 1, rack 1 are fixed on pedestal 2, on pedestal 2
It is additionally provided with test block supporting table 3, rack 1 is equipped with threaded post 5, and 5 lower end of threaded post is equipped with top board 4, and top board 4 and test block support
Platform 3 is arranged on same vertical plane；
The bottom surface of top board 4 is equipped with protective plate 11, and protective plate 11 uses section for the tubular structure of rectangle, and sectional dimension is big
In the sectional dimension of test block supporting table 3, the pedestal 2 is equipped with groove 10, and the lower end of protective plate 11 can extend to groove
In 10.
In preferred scheme, 301 two sides of supporting plane of the test block supporting table 3 are equipped with side block side 6, on side block side 6
Equipped with sliding slot 14,6 slide bar 7 when two side blocks are equipped between 6 perpendicular to side block, slide bar 7 is arranged in sliding slot 14, slide bar 7
It is equipped with bristle 8；
The supporting plane 301 is equipped with downward inclined surface 302 on wherein one end.
In preferred scheme, described 7 one end of slide bar passes through side block side 6 and extends to outside test block supporting table 3, slide bar 7
Knob 9 is equipped in one end outside test block supporting table 3.
In preferred scheme, connected between the top board 4 and threaded post 5 by bearing.
In preferred scheme, multiple springs 12,12 upper end of spring and protection are equidistantly laid in the groove 10
11 bottom surface of plate is fixedly connected, and lower end is fixed on 10 bottom surface of groove.
In preferred scheme, 11 bottom surface of protective plate is equipped with spring limiting board 13, and the upper end fixation of spring 12 is set
It sets on spring limiting board 13,13 two sides of spring limiting board and 10 liang of side contacts of groove.
The specific working principle is as follows for the present apparatus:
