Abstract

The utility model provides a fixing fixture of concrete tensile specimens, which is mainly used for fixing the specimens when the axial tensile strength, ultimate tension values and tensile elastic modulus of concrete is measured. The fixing fixture comprises side plates, positioning plates and a bottom plate, wherein, a mounting hole is formed at the middle part of the bottom plate; the side plates are symmetrically and fixedly mounted on the edges of the bottom plate; and the positioning plates are symmetrically mounted between the two side plates, so that the fixture with an upper opening is formed. The key technology of the fixing fixture lies in that the side plates are fixedly mounted on the edges of the bottom plate, and the positioning plates are mounted between the upper ends of the side plates through connecting rods. The fixing fixture has a simple structure, is convenient to use, can be automatically regulated, can guarantee that the specimens are closely combined with the positioning plates and the side surfaces of the specimens are stressed fully and evenly, improves the testing accuracy, and is convenient to carry.

Description

A kind of concrete tensile test piece stationary fixture
Technical field:
A kind of concrete tensile test piece stationary fixture is mainly used in when measuring concrete axial tensile strength, limit stretch value and tensile modulus of elasticity, and test specimen is fixed.
Background technology:
" 8 " font test specimen that the concrete tensile test piece is long 600mm, wide 100~196mm (middle part 220mm, long section are that 100mm is wide, and each 30mm of both ends, long section are that 196mm is wide, and each 160mm of two ends, long section are transition), 150mm is thick.Existing tensile test is the rib type groove anchor clamps clamping test pieces both ends with the top opening, again anchor clamps are installed on the universal testing machine and stretch, when the long section of 180mm is with interior fracture in the middle part of the test test specimen, its failing load, the pairing strain of failing load and the pairing strain of 50% failing load.Existing anchor clamps are fixture on four sides, just are difficult to be loaded into and clamping in case test specimen has drying shrinkage slightly or expands; Also have existing anchor clamps because structural reason from great, and is inconvenient to hand.
Summary of the invention:
Problem to be solved in the utility model provides a kind of simple in structure, easy to use at above deficiency exactly, can regulate automatically, can guarantee the anchor clamps that test specimen and location-plate are combined closely.Its technical scheme is as follows:
It comprises side plate, location-plate and base plate, and the middle part of base plate has mounting hole, at the edge of base plate symmetry fixed installation side plate, symmetrical installing and locating plate between biside plate, the anchor clamps of opening above constituting.Its gordian technique is that side plate is fixedly mounted on the base plate edge, passes through connecting link installing and locating plate between the upper end of side plate.
The beneficial effect that compared with prior art the utlity model has is:
1, location-plate of the present utility model is movable location-plate, can regulate automatically, simultaneously because be U type groove anchor clamps (test specimen is " 8 " font), increase along with tension, test specimen more closely combines with location-plate, guarantees that the test specimen side is fully evenly stressed, has improved testing precision;
2, the utility model has the hand-hold hole of symmetry on side plate, and is hand-held when making things convenient for the anchor clamps loading, unloading, alleviates the anchor clamps deadweight, saved material;
3, the utility model connects side plate and location-plate by connecting link, makes things convenient for the dismounting of anchor clamps, is easy to carry.

Fig. 2, the A that is Fig. 1 is to view;
Fig. 3, the B that is Fig. 2 is to view;
Fig. 4 is the utility model connecting thread cake structure synoptic diagram;
Fig. 5 is the utility model connection part structural representation.
Embodiment:
Referring to Fig. 1--Fig. 3, the utility model comprise side plate 1, location-plate 5 and base plate 9, and the middle part of base plate 9 has mounting hole 8, at the edge of base plate 9 symmetry fixed installation side plate 1, symmetrical installing and locating plate 5 between biside plate 1, the anchor clamps of opening above constituting.Its gordian technique is that side plate 1 is fixedly mounted on base plate 9 edges, having screw 2 in side plate 1 upper end of symmetry cooperates with connecting link 4, having through hole in location-plate 5 upper ends cooperates with connecting link 4, promptly between side plate 1 by connecting link 4 by through hole and screw 2 installing and locating plates 5, it is fixing with nut 7 that the back is installed, location-plate 5 upper ends are installed between the side plate, and lower end and base plate 9 have certain distance.Have the hand-hold hole 3 of symmetry on the side plate 1 of symmetry, hand-hold hole 3 can be for square, trapezoidal or circular.Location-plate 5 is provided with plate tooth 6, also convenient hand-held anchor clamps.The area of the anchor clamps top opening that constitutes makes anchor clamps constitute the U type groove anchor clamps of top opening greater than the area of base plate 9.
When carrying out tensile test,, screw thread cake 10 is installed in the mounting hole 8 of anchor clamps, by fabricated section 11 screw thread cakes 10 anchor clamps is fixed on the universal testing machine again as Fig. 4, shown in Figure 5.Form each other a pair of of symmetry by upper and lower two anchor clamps, upper and lower two anchor clamps are unloaded the location-plate 5 of the same side, put into test specimen, install location-plate again, start universal testing machine, along with the stressed increase in test specimen two sides, the test specimen surface is adjacent to gradually with anchor clamps.
