Abstract
The utility model provides a fixture device for a geosynthetic material tensile test. The fixture device comprises a rigid frame, a wedge-shaped clamp block, screw rod and a press strip, wherein the rigid frame is provided with a connecting head connected to a tension tester, and the screw rods, and the other end of the rigid frame is provided with the wedge-shaped clamp block used for holding a sample; the wedge-shaped clamp block is connected with the rigid frame by a mortise and tenon sliding groove; the press strip is arranged between the screw rods and the wedge-shaped clamp block. The fixture device adopts the wedge-shaped clamp block, so that even stress is applied to the sample in the whole width in the test process, and the influence on test results caused by local stress concentration of the sample can be avoided in the test process. Furthermore, a reset device is arranged, so that the sample is convenient to install.
Description
Technical field
The utility model relates to a kind of tensile test grip device, especially relates to a kind of geosynthetics tensile test grip device.
Background technology
In the time using common flat fixture to carry out the wide band of geosynthetics (100mm) tension test, because this body structure of fixture easily causes along specimen width holding force inhomogeneous, thereby generation stress raisers, make sample testing intensity lower than its actual strength.
Summary of the invention
The utility model provides a kind of geosynthetics test fixture device, and while having solved tension test, sample testing intensity is lower than the problem of its actual strength, and its technical scheme is as described below:
A kind of geosynthetics tensile test grip device, comprise rigid mount, wedge shape fixture block, screw rod, press strip, described rigid mount is provided with the connector and the screw rod that are connected on tension tester, the other end is provided with the wedge shape fixture block of placing sample, described wedge shape fixture block adopts Tenon chute to be connected with rigid mount, and described press strip is between screw rod and wedge shape fixture block.
Between described press strip and screw rod, be connected by silk mouthful.
Between described wedge shape fixture block and rigid mount, be provided with back-moving spring, for making wedge shape fixture block homing.
The surface that described wedge shape fixture block contacts with sample is provided with serrate anti-slip veins.
Described wedge shape fixture block is provided with the groove identical with press strip.
This device adopts wedge shape fixture block to make sample produce uniform stress at whole width in process of the test, has avoided the impact due to sample stress raisers, test findings being produced in process of the test.In addition, by resetting means is set, facilitated the installation of sample.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail,
Fig. 1 is the structural representation on the geosynthetics tensile test grip device top that provides of the utility model;
Fig. 2 is the side view of Fig. 1;
Wherein 1-connector; 2-back-moving spring; 3-rigid mount; 4-press strip; 5-wedge shape fixture block; 6-sample; 7-screw rod.
Embodiment
Geosynthetics tensile test grip device as depicted in figs. 1 and 2, comprise rigid mount 3, wedge shape fixture block 5, screw rod 7, press strip 4, described rigid mount 3 is provided with the connector 1 and the screw rod 7 that are connected on tension tester, the other end is provided with the wedge shape fixture block 5 of placing sample 6, between wedge shape fixture block 5 and rigid mount 3, adopts Tenon chute to be connected; Between press strip 4 and screw rod 7, be connected by silk mouthful; There is serrate anti-slip veins on the surface that wedge shape fixture block 5 contacts with sample 6.
When test, first use sample 6 is placed between the wedge shape fixture block 5 of fixture.Rotary screw 7 promotes press strip 4 downwards, gives certain holding force of sample 6 by wedge shape fixture block 5.In process of the test, due to the latching characteristics of wedge shape fixture block 5, the holding force that sample 6 is subject to increases gradually.After off-test, contra rotating screw 7 drives press strip 4 to rise, and wedge shape fixture block 5 automatically resets under the effect of back-moving spring 2, facilitates the installation of next test sample 6.
