Abstract
The utility model discloses a geosynthetics test clamp, comprising a rigid frame, wherein a wedge block is arranged inside the rigid frame; the wedge block is connected with the rigid frame by a tenon-and-mortise slide groove; a lateral fixing block is matched with the wedge block; an upper fixing block and a lower fixing block are also arranged at two sides of the lateral fixing block; and springs are arranged inside a hole of the upper fixing block and a hole of the lower fixing block, and anti-skid stripes are arranged at the surface of the wedge block contacting a sample. According to the geosynthetics test clamp provided by the utility model, the fixing device and the wedge block share the stress in common by adopting a wedge block self-locking device, so that fracture of the sample due to stress concentration on the clamp in a test process is avoided. In addition, installation of the sample is facilitated by adopting a reset device.
Description
Technical field
The utility model relates to a kind of test fixture, is specifically related to a kind of geosynthetics test fixture.
Background technology
When using common geosynthetics test fixture that GSZ class test specimen is tested, because test specimen itself is not very soft, anchor clamps can cause certain damage to sample when clamping, because stress is concentrated easily at anchor clamps place fracture, affect test result.
Summary of the invention
The utility model provides a kind of test specimen easy for installation, can not cause operation to test specimen, causes the geosynthetics test fixture of test specimen fracture.
The purpose of this utility model is achieved in that a kind of geosynthetics test fixture, comprises rigid frame, is provided with wedge in rigid frame, adopts the Tenon chute to be connected between wedge and the rigid frame; The side fixed block matches with wedge, also is provided with fixed block and lower fixed block in side fixed block both sides, is equipped with spring in the hole of the hole of upper fixed block and lower fixed block.
There is anti-skidding striped on the surface that wedge contacts with test specimen.
The geosynthetics test fixture that the utility model provides by the wedge self-locking device is set, shares stationary installation and wedge stressed jointly, avoids sample in the process of the test because stress concentrates on anchor clamps place fracture.In addition, by resetting means is set, made things convenient for the installation of sample.

Embodiment
The utility model adopts following structure: a kind of geosynthetics test fixture, comprise rigid frame 2, and rigid frame is provided with connecting screw rod 1, is provided with wedge 3 in rigid frame 2, adopts the Tenon chute to be connected between wedge 3 and the rigid frame 2; Side fixed block 7 matches with wedge 3, also is provided with fixed block 6 and lower fixed block 8 in side fixed block 7 both sides, is equipped with spring 9 in the hole of the hole of upper fixed block 6 and lower fixed block 8.
There is anti-skidding striped on the surface that wedge 3 contacts with test specimen 4.
The utility model installation wedge 3 processes are as follows: at first the installation side fixed block 7, installing fixed block 6, put into spring 9 again in 6 hole 10, then wedge 3 put into chute.Then in 8 hole 11 of lower fixed block, put into spring 9, be fixed on the rigid frame 28 again, finish the installation of wedge 3.All the other 3 wedges 3 in like manner are installed.
During test, stationary installation 5 is put between two wedges 3 of anchor clamps.Wedge 3 is along with stressed increase is locked gradually, and the friction force that itself and test specimen are 4 also increases gradually, makes whole stressedly jointly shared by stationary installation 5 and wedge 3.After test specimen 4 fractures, under the effect of spring 9, wedge 3 resets very soon, the installation of convenient next test specimen.
