Abstract
The utility model relates to a shear apparatus, and particularly relates to a test shear apparatus which is used for carrying out test on frictional resistance and the anti-shear fatigue performance between a water stable gravel layer and an asphalt layer. The test shear apparatus structurally comprises a bottom plate, wherein a baffle plate vertical to the bottom plate is fixed at one end of the bottom plate; a fixed shear ring is fixed on the bottom plate and used for fixing a cylindrical specimen to be tested; a spoke-type sensor is arranged on one side of the fixed shear ring; a movable shear ring capable of vertically moving is arranged on the other side of the fixed shear ring; a movable baffle plate is arranged on the outer side of the movable shear ring, and is used for providing constraining force in a horizontal direction to the specimen to be tested. Compared with the test shear apparatus in the prior art, the test shear apparatus has the characteristics of being reasonable in design, simple in structure, convenient to use, low in manufacturing cost and high in measurement accuracy.
Description
Technical field
The utility model relates to a kind of boxshear apparatus, particularly a kind of for carrying out the test boxshear apparatus of the steady metalling of water and brea bed interlayer friction resistance and shearing resistance experiment on fatigue properties.
Background technology
Under prior art, the shear test of being combined with the cement stabilized macadam interlayer for bituminous concrete, be interlayer friction resistance and the shearing strength at intersection fatigue behaviour when measuring different measures to improve interlayer conditions.At present, most test boxshear apparatus, structure is comparatively complicated, and this just causes between its assembly accuracy requirement high, just can obtain measurement data accurately, and then cause the cost up of test apparatus, is unfavorable for its universal use.
Summary of the invention
In order to solve the problem of prior art, the utility model provides a kind of test boxshear apparatus, and it is simple in structure, extremely is beneficial to laboratory and carries out shear test, and low being beneficial to of cost popularized use.
The technical scheme that the utility model adopts is as follows:
A kind of test boxshear apparatus, comprise base plate, described base plate one end is fixed with vertical with it baffle plate, be fixed with fixed shearing ring on base plate, it is for holding cylindrical test specimen to be measured, and a side of described fixed shearing ring is provided with wheel spoke type sensor, and opposite side is provided with vertically moving portable shearing ring, the arranged outside of described portable shearing ring has moving stop, and it is for providing the constraining force of horizontal direction to described test specimen to be measured.
Fixed shearing ring comprises the firm banking be fixed on base plate, and described firm banking top is hinged with semicircle clip.
Portable shearing ring comprises two semicircular clips, intert on base plate in fixing sliding bar the both sides of described clip, the top of upper half clip is connected with pressure head, described pressure head is for connecting MTS (Material testing system, universal testing machine), to provide vertical direction reciprocal power.
Floor below is fixed with column, and it is for being connected and fixed outside universal testing machine.
The beneficial effect that the technical scheme that the utility model provides is brought is:
Test boxshear apparatus of the present utility model, it measures horizontal restraint power by wheel spoke type sensor, and utilize outside MTS to be with dynamic head, thereby vertically move portable shearing ring, the test specimen to be measured be fixed in fixed shearing ring and portable shearing ring is applied to reciprocal shearing force, the shearing force that can destroy test specimen by measuring this, reach interlayer friction resistance while measuring different measures to improve interlayer conditions and the purpose of shearing strength at intersection fatigue behaviour.
