It causes, the interior outer radius of the two is consistent；Inner corner trim step C on external corner step B height and top layer outer cover on the index bed outer cover
Depth it is consistent, the interior outer radius of the two is consistent；So as to ensure to contact close, gap of not boxing out, it is ensured that pour between different outer covers
Specimen Shape out is the hollow cylindrical of standard.
Further, the height of the external corner step B of the index bed outer cover is consistent with inner corner trim step B depth, passes through increase and decrease
The number of plies of index bed outer cover controls the height of test specimen.
Further, the ear A, ear B, there are two tapping thread holes on ear C, respectively will using screw and nut
Two ear A, two ear B, two ear C are tightened, so that two pieces of consistent curved plate A, curved plate B, arcs
Steel plate C can be fitted closely from each other.
The beneficial effects of the invention are as follows：
1st, the present invention can be by adjusting the position of bottom outer cover and hollow cylinder on die trial pedestal so as to obtain not
The mortar specimen of stack pile meets different tests demand.
2nd, present invention introduces index bed outer covers, on the one hand can accomplish placement layer by layer, help to ensure that pouring quality, another
Aspect can adjust the height in tunnel by adjusting the number of plies of index bed outer cover.
3rd, multiple tracks concentric grooves are carved on die trial pedestal of the invention, not only play fixed die trial liner and die trial outer cover
Effect, and disclosure satisfy that needed for different tests, it is cost-effective.
4th, the die trial outer cover of the present invention 180 ° curved plates consistent for two pieces, and handle is welded with, carrying and form removal side
Just, and influence of the form removal to test specimen can be reduced.
