Description
Technical field
This utility model belongs to asphalt material test instrument technical field, it particularly relates to arrive a kind of asphalt
Indirect tensile test on frozen-thaw fixture.
Background technology
Indirect tensile test on frozen-thaw is simplified by U.S. AASHTO T 283Lottmen methods, under prescribed conditions to drip
Blue or green compound carries out freeze-thaw cycle, with compound test specimen by cleavage fracture strength ratio before and after Moisture Damage evaluating Colophonium mixing
The anti-water damage ability of material.Needing the marshal piece that will be prepared to be placed on diametral compression test fixture in process of the test carries out splitting examination
Test.The lower press strip of generally fixture is fixed on fixture, the elongated structure of press strip cause operator need to adjust repeatedly could incite somebody to action
The center of circle of marshal piece is directed at the center of press strip.If test specimen center directly can be fixed on press strip by a kind of novel clamp of design
Center, not only can reduce test error and can also improve test efficiency.
The content of the invention
To solve above-mentioned technical problem, this utility model provides a kind of simple structure, the asphalt of simple operation
Indirect tensile test on frozen-thaw fixture.
A kind of asphalt indirect tensile test on frozen-thaw fixture described in the utility model, the test fixture include base plate 1,
Motor 2 and clamping plate 3;The base plate 1 includes ceiling molding and lower press strip, and both constitute ┻ tee sections;The surface of the ceiling molding sets
There is pressure transducer;Pressure transducer is connected to motor 2 by control unit;Transverse concave groove is provided with the middle part of the lower press strip;
The clamping plate 3 has two parts, is the left side clamping plate and right side clamping plate for constituting V-shaped section;Left side clamping plate and right side clamping plate difference
Inserted in the transverse concave groove of ceiling molding both sides by the slide block of bottom;The slide block connects motor 2.
A kind of asphalt indirect tensile test on frozen-thaw fixture described in the utility model, the base plate 1 and clamping plate 3 are by metal
Material is constituted.
A kind of asphalt indirect tensile test on frozen-thaw fixture described in the utility model, the motor 2 have two, are located at bottom
The two ends of plate 1.
During on-test, left and right sides clamping plate causes test specimen center and press strip center alignment, has a rest when ceiling molding touches horse
During your test specimen, signal is passed to control unit by the pressure transducer of ceiling molding, and control unit promotes Motor drive slide block, left and right two
Side clamping plate is moved to both sides of the edge along groove so that clamping plate and test specimen depart from, it is ensured that follow-up test is accurately carried out.
Compared with prior art, asphalt indirect tensile test on frozen-thaw clamp structure described in the utility model is simple, behaviour
Make convenient, accurately can realize, by the marshal piece center of circle and press strip center alignment, greatly reducing personal error, improve examination
Test accuracy.

Specific embodiment
With reference to specific embodiment asphalt indirect tensile test on frozen-thaw fixture described in the utility model is done into
One step is illustrated, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of asphalt indirect tensile test on frozen-thaw fixture, including base plate 1, motor 2 and clamping plate 3;The base plate 1 includes
Press strip and lower press strip, both constitute ┻ tee sections;The surface of the ceiling molding is provided with pressure transducer;Pressure transducer is by control
Unit processed is connected to motor 2;Transverse concave groove is provided with the middle part of the lower press strip;The clamping plate 3 has two parts, is to constitute V-shaped
The left side clamping plate and right side clamping plate in section;Left side clamping plate and right side clamping plate insert ceiling molding both sides by the slide block of bottom respectively
In transverse concave groove;The slide block connects motor 2.The base plate 1 and clamping plate 3 are made up of metal material.The motor 2 has two,
It is located at the two ends of base plate 1.
When the ceiling molding contact marshal piece of testing equipment, the pressure transducer of ceiling molding is signaled to motor,
Make which order about slide block to move back and forth along groove.The V-structure that left side clamping plate and right side clamping plate are constituted is used for centralized positioning, can
The center of the center of circle alignment press strip of marshal piece is made, to improve the accuracy of test.Both sides clamping plate bottom carries slide block, leads to
Cross slide block left and right sides clamping plate to move back and forth inside bottom plate groove.The angle and plate width of both sides clamping plate can be according to horse
Xie Er sample dimensions are adjusted.
During on-test, left and right sides clamping plate causes test specimen center and press strip center alignment, has a rest when ceiling molding touches horse
During your test specimen, signal is passed to control unit by the pressure transducer of ceiling molding, and control unit promotes Motor drive slide block, left and right two
Side clamping plate is moved to both sides of the edge along groove so that clamping plate and test specimen depart from, it is ensured that follow-up test is accurately carried out.
Compared with prior art, asphalt indirect tensile test on frozen-thaw clamp structure described in the utility model is simple, behaviour
Make convenient, accurately can realize, by the marshal piece center of circle and press strip center alignment, greatly reducing personal error, improve examination
Test accuracy.
