The utility model discloses an anchor clamps can be reliable and stable press from both sides the test piece tight, in test procedure, avoid skidding, shifting the scheduling problem, make the test result accurate.
Description
Technical field
Present patent application relates to geosynthetics detection technique field.
Background technology
Geosynthetics needs the test accepting puncture resistance intensity, for the ability of evaluation test thing opposing particle injection.The fixture that existing geosynthetics punctures strength test there will be the situation of easily skidding mostly, causes puncturing strength test data and there is comparatively big error.Structure, existing fixture adopts two circle screw threads clamping tested person samples, then fixes with three holding screws, punctures in strength test process what carry out high-strength geotextile and related products thereof, sample easily skids, be shifted, and fixture does not reach the requirement of fastening test specimen.In addition, existing fixture is irony material, gets rusty easily.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provide a kind of can geosynthetics pierce force test unit clamp, the problem of skidding can be solved.
To achieve these goals, the utility model takes following technical scheme: geosynthetics punctures the unit clamp of strength test, comprise base, annulus top cover and some fastening bolts, described base comprises circular platform and a bottom bracket, described circular platform is in the top of bottom bracket, circular platform is overlapping up and down with annulus top cover, central authorities are provided with the central perforation that availability test push rod runs through, the upper surface of circular platform arranges a circle shape groove, accordingly, the lower surface of annulus top cover is provided with a circular projection, geosynthetics sample holder to be measured is placed between annulus top cover and circular platform, circle shape groove and circular projection be mutually engaged geosynthetics sample to be measured clamped fixing, described annulus top cover is removably fixedly connected with relative to described base by described fastening bolt.
Described fastening bolt circumference is uniform and protrude from the upper surface of the circular platform of institute, and described annulus top cover circumference is evenly equipped with some circular holes and passes for described fastening bolt, and described fastening bolt passes described circular hole and fixes with nut.
Preferably, described fastening bolt has four.
Preferably, the bottom land of described annular recess is provided with antiskid thread.
The Kong Xinyu of described central perforation tests the axis coinciding of push rod.
Fixture of the present utility model can be reliable and stable by test specimen clamp, in test process, avoid the problems such as skidding, displacement, make test result accurate.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
Fig. 3 is the structural representation of the circular platform of the utility model base.
Wherein: base 1, circular platform 2, fastening bolt 3, annulus top cover 4, central perforation 5, circular protruding 6, circle shape groove 7, central perforation 8, nut 9, sample 10.
Embodiment:
As shown in Figure 1, for geosynthetics of the present utility model punctures the unit clamp of strength test, this fixture comprises four uniform fastening bolts 3 of base 1, annulus top cover 4 and circumference.
As shown in Figure 1, base 1 bottom bracket that comprises a circular platform 2 and provide a supporting role for circular platform 2.Circular platform 2 central authorities are provided with the central perforation 8 that availability test push rod runs through, and the upper surface of circular platform arranges a circle shape groove 7.Four fastening bolts 3 circumference is uniform and protrude from the upper surface of circular platform 2.
Annulus top cover 4 and circular platform be overlapping up and down to be placed, the central authorities of annulus top cover 4 are provided with the central perforation 5 that availability test push rod runs through.The lower surface of annulus top cover is provided with one circular protruding 6 in the position that the circle shape groove 7 to circular platform is corresponding.Annulus top cover 4 circumference is evenly equipped with four circular holes, passes for fastening bolt 3.
Geosynthetics sample 10 to be measured is folded between annulus top cover 4 and circular platform 2, circle shape groove 7 is engaged mutually with circular protruding 6, thus geosynthetics sample 10 to be measured is fixedly clamped between annulus top cover 4 and circular platform 2, fastening bolt 3 is tightened with nut 9 through after the circular hole of annulus top cover 4.
The range of selection power makes output valve between 10% ~ 90% of full scale.The travelling speed of setting testing machine is 300mm/min, sample, when no-station pole canopy and wrinkle, is fixed on novel clamp, guarantees that sample can not produce slippage, the novel clamp clipping sample is placed on testing table, makes the axle center of central perforation and the axis coinciding testing push rod.Starting characteristics test instrument, until sample is punctured, record maximal value, what it was this sample punctures brute force.
The whole component parts of fixture all adopts stainless steel.
