Abstract
The utility model relates to a mechanical testing clamp for a cold-rolled torsion reinforcing bar. A right clamp is provided with a right semicircular slot bore 2, a left clamp 4 is provided with a left semicircular slot bore 3, and the right semicircular slot bore 2 and the left semicircular slot bore 3 are provided with internal threads 5. The clamp can ensure even stress of a cold-rolled torsion reinforcing bar in a pull test, test data are accurate and reliable, and the entire tensile test can be carried out successfully.
Description
The utility model relates to cold-rolled torsion steel bar mechanical test clamp technology field.
Cold-rolled torsion steel bar with flat chuck clamping, makes reinforcing bar be subjected to pulling force and horizontal shearing resistance effect discontinuity when doing tension test near the chuck at present, makes the reinforcing bar fracture position all in the chuck end, therefore can't reflect the real tensile strength of cold-rolled torsion steel bar.
The purpose of this utility model be the design a kind of cold-rolled torsion steel bar mechanical test anchor clamps since its clamping hole be the circle, in screw thread is arranged, make clamping firm, reinforcing steel bar bear is even, makes the test figure of making truly reflect tensile strength of reinforcement.
The utility model is achieved in that on the right anchor clamps 1 right semi-circle slotted eye 2, on the left anchor clamps 4 left semicircle slotted eye 3 is arranged, and on right semi-circle slotted eye 2 and the left semicircle slotted eye 3 internal thread 5 is arranged.
The utility model has the advantages that: simple in structure, cost is low, long service life, and clamping is firm, makes the even reinforcing bar of reinforcing steel bar bear all in the middle part fracture, has truly reflected tensile strength of reinforcement.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment;
Fig. 1 is a front view, and Fig. 2 is a vertical view.
In the accompanying drawing: 1, right anchor clamps, 2, the right semi-circle slotted eye, 3, the left semicircle slotted eye, 4, left anchor clamps, 5, internal thread.
Right anchor clamps 1 and left anchor clamps 4 are fixed on the testing table, cold-rolled torsion steel bar is placed between right semi-circle slotted eye 2 and the left semicircle slotted eye 3, this moment steps up right anchor clamps 1 and left anchor clamps 4 are firmly fixed reinforcing bar, the contact area that has internal thread 5 to increase anchor clamps and reinforcing bar within adding increases friction force, and reinforcing bar can be carried out when doing tension test smoothly.
Claims (1)
1, cold-rolled torsion steel bar mechanical test anchor clamps is characterized in that: right semi-circle slotted eye (2) is arranged on the right anchor clamps (1), left semicircle slotted eye (3) is arranged on the left anchor clamps (4), on right semi-circle slotted eye (2) and the left semicircle slotted eye (3) internal thread (5) is arranged.
