Description
Technical field
The invention belongs to the improvement of long cube specimen test fixture structure, particularly a kind of long cube specimen axially draws
Stretch test fixture.
Background technology
At present, testing long cube specimen axial tension test mainly has two kinds, when one kind is shaping test piece, except in test specimen
Portion keeps uiform section cube external, and two ends gradual change increases the area of rectangular cross-sectional, to reach under axial tension effect, fracture
It is at the uiform section cube at middle part, such as：《Concrete for hydraulic structure testing regulationss》Concrete axial tension examination in SL352-2006
Test.The method shortcoming test specimen, only through die trial molding, can be tested, for field investigation and sampling test specimen then process very tired
Difficult；Second is then test specimen two ends to be glued on fixture using strength test, such as《Hydraulic asphalt concrete test rule
Journey》Bituminous concrete tension test in DL/T5362-2006.The shortcoming time of the method is long, when that is, plybonding effect needs waiting
Between, and after off-test, the more difficult taking-up of test specimen of residual in the chuck of test specimen two ends bonding, the reuse of impact chuck.
Content of the invention
It is an object of the invention to provide a kind of long cube specimen axial tension test fixture, not only rational in infrastructure, property
Energy is safe and reliable it is adaptable to comprcssive strength is more than the test specimen of more than 5 times resistance strength materials, and test specimen handling ease,
Chuck is reusable.
The object of the present invention is achieved like this：A kind of long cube specimen axial tension test fixture, cross support arm
Each support arm outer end is respectively articulated with symmetrical two pull bar, the four edges of square frame is respectively articulated with and pull bar phase
Corresponding lever arm, the outer end of lever arm is hinged with the corresponding pull bar other end respectively, the articulated clamping plate in inner end of lever arm,
Pawl is uniformly arranged on the work surface of clamping plate, the work surface of clamping plate is matched with test specimen, on cross support arm top
Centrally disposed the draw ring in face.
The principle of the present invention：Employ and pulling force is converted to pressure clamping test specimen two ends, and with pulling force in process of the test
While increase, pressure is also gradually increased it is ensured that tightly clamping the purpose of test specimen two ends.The technical essential of this test fixture has four
Individual aspect：One is for being transmitted using connecting rod, and pulling force is changed into the pressure to test specimen two ends；Two is in order to avoid pressure at two ends is made
Become clamping plate edge test specimen stress concentration, clamping plate is both designed as along test specimen two ends, ecto-entad is gradually by thick thinning, test specimen two ends pressure
Stress also from large to small, reduces the stress concentration of clamping plate edge test specimen；Three is that clamping plate all employs pawl design it is ensured that right
The requirement of test specimen clamping.
The using method of the present invention：
One end of long cube specimen is put in present clip, makes clamping plate around test specimen, gently put on draw ring, pull bar is to upper band
Dynamic lever, clamping plate is clamped the surrounding of test specimen upper end；
The other end of long cube specimen is put in another symmetrical present clip, makes clamping plate around test specimen, gently lift ring,
Pull bar drives downwards lever, chuck is clamped the surrounding of test specimen lower end；
By above-mentioned steps, after making the clamp test specimen of two groups of present invention, fixture is placed on universal test together with test specimen
On machine, and hook the draw ring of two present invention respectively, you can carry out axial tension test.
The present invention is not only rational in infrastructure, and performance safety is reliable it is adaptable to comprcssive strength is more than more than 5 times resistance strength materials
Test specimen, and test specimen handling ease, chuck is reusable.
