Description
Technical field
This utility model belongs to the improvement of long cube specimen test fixture structure, particularly a kind of long cube specimen axle
To tensile 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.
Utility model content
The purpose of this utility model is to provide a kind of long cube specimen axial tension test fixture, and not only structure is closed
Reason, performance safety is reliable it is adaptable to comprcssive strength is more than the test specimen of more than 5 times resistance strength materials, and test specimen processing
Easily, chuck is reusable.
The purpose of this utility model is realized in：A kind of long cube specimen axial tension test fixture, cross
Each support arm outer end of support arm is respectively articulated with symmetrical two pull bar, and the four edges of square frame are respectively articulated with
The lever arm corresponding with pull bar, the outer end of lever arm is hinged with the corresponding pull bar other end respectively, the inner end hinge of lever arm
Then clamping plate, is uniformly arranged pawl, the work surface of clamping plate is matched with test specimen, in cross on the work surface of clamping plate
Centrally disposed the draw ring of support arm top surface.
Principle of the present utility model：Employ by pulling force be converted to pressure clamping test specimen two ends, and in process of the test with
While pulling force increases, 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
There are four aspects：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 two side pressures
Power causes clamping plate edge test specimen stress concentration, and clamping plate is both designed as along test specimen two ends, and ecto-entad is gradually by thick thinning, test specimen two
Side pressure stress also from large to small, reduces the stress concentration of clamping plate edge test specimen；Three be clamping plate all employ pawl design it is ensured that
Requirement to test specimen clamping.
Using method of the present utility model：
One end of long cube specimen is put in this utility model fixture, makes clamping plate around test specimen, gently put on draw ring, draw
Bar brings up lever, clamping plate is clamped the surrounding of test specimen upper end；
The other end of long cube specimen is put in another symmetrical this utility model fixture, makes clamping plate around test specimen,
Light lifting ring, pull bar drives downwards lever, chuck is clamped the surrounding of test specimen lower end；
By above-mentioned steps, after making two groups of clamp test specimens of the present utility model, fixture is placed on together with test specimen
On universal testing machine, and hook two draw rings of the present utility model respectively, you can carry out axial tension test.
This utility model 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 intensity
The test specimen of material, and test specimen handling ease, chuck is reusable.
Brief description
Below in conjunction with accompanying drawing, this utility model is further described, Fig. 1 illustrates for this utility model front view structure
Figure, Fig. 2 is this utility model left view structural representation, and Fig. 3 is this utility model overlooking the structure diagram, and Fig. 4 is that this practicality is new
Type use state structural representation.
Specific embodiment
A kind of long cube specimen axial tension test folder, as shown in Figure 1, Figure 2, Figure 3, Figure 4, cross support arm 1
Each support arm outer end is respectively articulated with symmetrical two pull bar 2, the four edges of rectangular frame 5 is respectively articulated with and pull bar 2
Corresponding lever arm 4, the outer end of lever arm 4 is hinged with corresponding pull bar 2 other end respectively, and the inner end of lever arm 4 is hinged
Clamping plate 3, pawl is uniformly arranged on the work surface of clamping plate 3, the work surface of clamping plate 3 is matched with test specimen 7, in cross
Centrally disposed the draw ring 6 of shape support arm 1 top surface.Each support arm outer end of cross support arm 1 is respectively provided with two hinges
Joint chair, by the articulated two symmetrical pull bars 2 of hinged seat.The hinged face of clamping plate 3 is the inclined plane shunk inwards, inclined plane with
The angle of plumb line is 3 ° -6 °.
