Have a great influence.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided it is a kind of propose it is simple in construction, easy to operate practical
Test block diametral compression test fixture, concrete technical scheme is as follows：
One kind is used to detect building test block diametral compression test fixture, including upper fixture and lower clamp, the upper fixture and described
Lower clamp is correspondingly arranged, and the upper fixture lower surface sets lower platen along its longitudinal direction, and this pushes plate surface and sets raised, institute
State lower clamp upper surface and be symmetrical arranged at least one pair of locating slot in its longitudinal midline direction both sides, install and hold in the locating slot
Pressing plate, pad is installed on the bearing plate, baffle plate is provided with both sides of the lower clamp along its longitudinal direction.
Preferably to realize the utility model, may further be：The lower platen lower surface is semicircle projective structure, and
The lower platen is integrally formed with the upper fixture.
Further, the projection has downwardly projecting arcuate lower surface, and the raised both sides are connected with strap, institute
State and raised be connected with the lower platen using removably.
Further, two screws are at least opened up in the locating slot, the bearing plate passes through screw with the locating slot
Connection.
Further, the pad has curved upper surface protruding upward, and the pad both sides are connected with fixing clip, institute
Fixing clip is stated to be connected using removably with the bearing plate.
Further, the upper fixture corner is provided with contiguous block, and the contiguous block is connected by screw and forcing press upper punch
Connect.
Further, the locating slot is three pairs, is respectively cooperating with usingWithCircle
The test block of cylinder.
Further, the upper fixture lateral length is less than lower clamp lateral length.
Compared with prior art, the beneficial effects of the utility model are：First, the utility model coordinates universal testing machine to enter
Row operation, without manufacturing special diametral compression test machine, reduces experimentation cost；Second, lower plate sets three pairs of locating slots, with suitable
Cylinder, the square test block test of different size are closed, also allows for the dismounting of bearing plate, is cleared up, while make the structure of the device
It is more stable；It third, setting baffle plate in the both sides of bearing plate, can effectively prevent test block from, because stress is too big, bursting apart, try
Block collides universal testing machine side wall, causes universal testing machine to damage；Fourth, locating slot installs bearing plate, test block is placed on
Between two pieces of bearing plates, make test block more stable, be easy to test operation.
