5 matched longitudinal chutes 51 guarantee that side will not occur for pressing plate 3 under pressure so as to effectively transmit compressed stress
To offset.
As shown in Fig. 2, being equipped with limit spring 52 in sliding slot 51, which is fixed at 51 bottom of sliding slot
Portion, the other end are abutted against with sliding block 5.Therefore, when sliding block 5 is moved at limit spring 52 and be compressed to can not push again after,
The depressed position of pressing plate 3 is just concordant with 1 upper surface of test piece mould at this time, prevents from pressing plate 3 pressure is excessive in a flash to lead to aggregate
The case where destruction, occurs.
The working principle of this pervious concrete die trial: resistance to compression die trial tackling 2 is installed on test piece mould 1, then in sky
Intracavitary loading pervious concrete mixture, and upper surface is flattened, pressing plate 3 is attached on the first strut 31 at this time, and make pressing plate 3
It is contacted with concrete upper surface, rotates with it handwheel 42, is i.e. the holding of connecting rod 41 rotates coaxially, first bevel gear 45 and the second cone tooth
46 engaged transmission of wheel rotates the second strut 32, and driving the first strut 31 followed by screw thread, 51 directions are displaced along the chute, right
Pervious concrete implements pressure forming.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
