Abstract
The utility model discloses a clamp for the steel strand tensile test. The clamp for the steel strand tensile test comprises two half clamping devices; either half clamping device comprises a clamping base, a connecting block and a clamping block, wherein one side surface of the clamping base is an inclined surface of the clamping base, a connecting block slot is arranged on the inclined surface, the connecting block is also provided with an inclined surface matched with the inclined surface of the clamping base, the inclined surface of the inclined surface is arranged in the connecting block slot of the clamping base, the connecting block can move along the connecting block slot, the clamping block is fixed on the side surface opposite to the inclined surface of the connecting block, an anchoring part clamping groove is arranged on the side surface opposite to the connecting block of the clamping block, and the width L of the connecting block slot is not larger than 50mm. By adopting the clamp for the steel strand tensile test, jittering or sudden shifting of the connecting block are not easy to happen, the phenomenon that the maximum tensile force in the existing test is low is eliminated, and the accuracy of test data is ensured, and the test is ensured to be carried out smoothly.
Description
Technical field
The utility model relates to a kind of road test instrument, the anchor clamps that the tension of steel strand strength test of more specifically saying so is used, dependent territory worker's test apparatus technical field.
Background technology
In bridge, large scale prefabricated plate such as overhead, generally be provided with steel strand wires, steel strand wires pass prefabricated board two ends, and two ends are fixed by anchoring piece.Wherein anchoring piece comprises overcoat and sandwich, and outer casing inner wall and sandwich outer wall have the inclined-plane that is complementary, and sandwich is subjected to the pulling force of steel strand wires, makes sandwich be subjected to the extruding force of overcoat, thereby clamps the steel strand wires in the sandwich.Because steel strand wires are used for strengthening the intensity of bridge, large scale prefabricated plate such as overhead, therefore, need test the tension intensity of steel strand wires usually.
The omnipotent machine of the general employing of the pulling experiment of steel strand wires, omnipotent facility have two relatively-movable support bodys, are fixed on support body by the steel strand wires anchor clamps, and the anchoring piece with one or some steel strand wires two ends is fixed in the anchor clamps then, movable support body is carried out the tension of steel strand strength test.
The anchor clamps of existing tension of steel strand test usefulness comprise two and half clamp devices, each half clamp device comprises holder, contiguous block and fixture block, holder has the inclined-plane, steel strand wires when so-called inclined-plane is this face and tension of steel strand test have certain angle, on the inclined-plane, be provided with a contiguous block slot, contiguous block also has one and inclined-plane, this inclined-plane of contiguous block is in the contiguous block slot of holder, contiguous block can move along the contiguous block slot, fixing fixture block on the relative side, contiguous block inclined-plane is provided with the anchoring piece clip slot on the side of the relative contiguous block of fixture block.Said structure, when tension of steel strand is tested, be subjected to pulling force after, fixture block moves in the contiguous block slot together with contiguous block, makes the fixture block of two and half clamp devices of anchor clamps close, the fixture block of such two and half clamp devices is near gripping anchoring piece more.The clamp structure of existing this tension of steel strand test usefulness is reasonable, and test effect is also good.But, the width L of the contiguous block slot of its anchor clamps is generally greater than 100mm, because the width of contiguous block slot is big, make the friction factor between contiguous block slot and the contiguous block also bigger, therefore when tension of steel strand is tested, tend to generation shake or contiguous block and be shifted suddenly, it is on the low side to be easy to generate the twisted wire maximum pull, influenced the accuracy of test figure, even can abort.
The utility model content
At the problems referred to above, when the problem that the utility model quasi-solution is determined provides the test of a kind of tension of steel strand, be not easy to produce the anchor clamps of the tension of steel strand test usefulness of shake or contiguous block displacement suddenly, carry out smoothly with the accuracy and the test of warranty test data.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of anchor clamps of tension of steel strand test usefulness, it comprises two and half clamp devices, described each half clamp device comprises holder, contiguous block and fixture block, a side of described holder is the holder inclined-plane, is provided with a contiguous block slot on described inclined-plane; Described contiguous block also has an inclined-plane that is complementary with the holder inclined-plane, this inclined-plane of described contiguous block is in the contiguous block slot of holder, described contiguous block can move along the contiguous block slot, described fixture block is fixed on the relative side, contiguous block inclined-plane, be provided with the anchoring piece clip slot on the relative side of the contiguous block of described fixture block, the width L of described contiguous block slot is not more than 50 millimeters.
As preferably, the width L of described contiguous block slot is the 30-50 millimeter.
Adopted said structure, because the anchor clamps of tension of steel strand test usefulness of the present utility model, reduced the width L of contiguous block slot, make the contiguous block slot be not more than 50 millimeters, effectively reduced the surface of contact between contiguous block slot and the contiguous block like this, friction factor between contiguous block slot and the contiguous block is reduced, when therefore tension of steel strand is tested, being not easy generation shake or contiguous block is shifted suddenly, eliminate maximum pull phenomenon on the low side in the existing test, guaranteed that the accuracy of test figure is carried out smoothly with testing.

Fig. 3 is the structural representation of twisted wire tension tester.
Among the figure: 1-holder, 2-contiguous block, 3-fixture block, 4-contiguous block slot, 5-anchoring piece clip slot, 6-holder inclined-plane, 7-steel strand wires, 8-support body.
Embodiment
As shown in Figure 1 and Figure 2, the anchor clamps of tension of steel strand test usefulness of the present utility model, it comprises two and half clamp devices, described each half clamp device comprises holder 1, contiguous block 2 and fixture block 3, a side of described holder 1 is holder inclined-plane 6, is provided with a contiguous block slot 4 on described inclined-plane 6; Described contiguous block 2 also has an inclined-plane that is complementary with holder inclined-plane 6, this inclined-plane of described contiguous block 2 is in the contiguous block slot 4 of holder, described contiguous block 2 can move along contiguous block slot 4, described fixture block 3 is fixed on the relative side, contiguous block inclined-plane, on the relative side of the contiguous block 2 of described fixture block 3, be provided with anchoring piece clip slot 5, the anchor clamps of the tension of steel strand test usefulness of said structure and prior art are similar, therefore no longer launch.
The characteristics of the anchor clamps of tension of steel strand test usefulness of the present utility model are: the width L of described contiguous block slot 4 is not more than 50 millimeters, is generally the 30-50 millimeter.
Referring to Fig. 3, in the tension of steel strand test, adopt two anchor clamps, two anchor clamps are separately fixed on two support bodys 8 of omnipotent machine, by moving of two support body 8 relative directions, make steel strand wires 7 be subjected to pulling force, thereby test.
