Abstract
The utility model relates to a kind of compound direct shear performance test fixture of supporting UTM testing machine, and this device comprises base and the stationary fixture that is fixed on described base and stopper slot.The top of described stopper slot is provided with pressure head, is provided with described stationary fixture before it, and its back side is embedded with mobile draw-in groove, and this top of moving draw-in groove is flexibly connected with described stopper slot; Described stationary fixture and described mobile draw-in groove are equipped with through hole.The utility model structure is simple, easy to implement, not only can accurate recording process of the test load-time curve, also very intuitively can arrive the shear behavior at different compound interface; Also solve current concrete direct shear grip device simultaneously and form the shortcomings such as complicated, test data is discrete.
Description
Technical field
The utility model relates to pavement detection technical field, particularly relates to a kind of compound direct shear performance test fixture of supporting UTM testing machine.
Background technology
It is shearing strength the weakest point between supercrust.Between each layer of bituminous pavement and the modulus of cement concrete-bituminous concrete composite pavement interlayer inconsistent, expansion coefficient is not identical yet, shear failure easily under the effect of load stress and temperature stress between genetic horizon, particularly under the horizontal thrust of vehicle launch, braking, easily there is slippage, gather around the destructions such as bag in road surface due to shearing strength at intersection scarce capacity.
At present, China not yet forms unified standard to the test specification of shearing strength at intersection performance evaluation, causes to be with when choice and operation binding material to bear the character of much blindness, and cannot operate according to different actual conditions, make quality control and detection difficulty, cause road surface easily to produce interlaminar failure.Meanwhile, China is also undetermined to the evaluation method of cutting performance, also has some shears in boundary, but there is the shortcomings such as device formation is complicated, test data is discrete, there is certain impact to test findings.
Utility model content
Technical problem to be solved in the utility model is to provide the compound direct shear performance test fixture that a kind of structure is simple, test supporting UTM testing machine accurately.
For solving the problem, the compound direct shear performance test fixture of a kind of supporting UTM testing machine described in the utility model, is characterized in that: this device comprises base and the stationary fixture that is fixed on described base and stopper slot; The top of described stopper slot is provided with pressure head, is provided with described stationary fixture before it, and its back side is embedded with mobile draw-in groove, and this top of moving draw-in groove is flexibly connected with described stopper slot; Described stationary fixture and described mobile draw-in groove are equipped with through hole.
The below of described stationary fixture is connected with described base by diagonal rib.
The aperture of described through hole is 100mm.
The utility model compared with prior art has the following advantages:
1, the utility model can be connected directly between the shearing strength of UTM universal testing machine being tested concrete interface, numerical value is gathered by Acquisition Instrument, display on computers, not only can accurate recording process of the test load-time curve, also very intuitively can arrive the shear behavior at different compound interface; Also solve current concrete direct shear grip device simultaneously and form the shortcomings such as complicated, test data is discrete.
2, the utility model have employed the combination of stationary fixture and dismountable moving draw-in groove, therefore, can accurately locate.
3, the utility model structure is simple, easy to implement, can carry out the test findings under different tests speed and test temperature.

Embodiment
As shown in Figure 1, a kind of compound direct shear performance test fixture of supporting UTM testing machine, this device comprises base 2 and the stationary fixture 3 that is fixed on base 2 and stopper slot 4.The top of stopper slot 4 is provided with pressure head 6, is provided with stationary fixture 3 before it, and its back side is embedded with mobile draw-in groove 5, and this top of moving draw-in groove 5 is flexibly connected with stopper slot 4; Stationary fixture 3 and mobile draw-in groove 5 are equipped with through hole.
Wherein: the below of stationary fixture 3 is connected with base 2 by diagonal rib 1.
The aperture of through hole is 100mm.
During use, sample to be tested 7 is as shown in Figure 3 placed in UTM testing machine, takes out after constant temperature 2h at an established temperature.Sample to be tested 7 one end is placed in stationary fixture 3, makes the inner side by cutting interface and be just in stationary fixture 3.Pull down mobile draw-in groove 5, mobile draw-in groove 5 is inserted in stopper slot 4 from top to bottom, adjust mobile draw-in groove 5, make it keep both sides level.The utility model that sample to be tested 7 is housed is placed in UTM testing machine, makes pressure head 6 and testing machine depression bar just right, operated by computer software, under the speed of regulation, carry out straightway testing, curve map as shown in Figure 2 can be obtained.
