Description

Technical Field

[0001] The utility model relates to the technical field of detection fixtures, in particular to a detection fixture for threaded steel. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars. Due to the effect of the threaded ribs, rebar has a large bonding strength with the concrete mortar interface and can withstand strong external forces. It is widely used in civil engineering construction such as houses, bridges and roads. Rebar needs to be subjected to performance bending testing before use, and a clamp is needed to limit the rebar during the bending test.

[0003] In order to improve the effect of clamping threaded steel, the prior art has made many improvements to the detection fixture of threaded steel, such as the patent authorization announcement number CN212134333U, which discloses a threaded steel detection fixture, including a base, a base welded to the top of the base, a screw running through the inside of the base, one end of the screw connected to a connector, both ends of the connector are rotatably connected to a shaft, the bottom end of the shaft is connected to a moving ring, the inner end of the base is welded with a limit rod near the position of the moving ring, the limit rod is located inside the moving ring, and the outer end of the moving ring is welded with a connecting block. This utility model relates to the technical field of threaded steel, and through the rotating kit and the bearing, it is convenient to rotate the screw, so that the screw drives the connector to move, and through the shaft, it is convenient to drive the moving ring to move outside the limit rod when the screw moves, thereby driving two semicircular clamping rings to move closer to each other, so as to clamp and fix one end of the threaded steel, and clamp the threaded steel through the clamping block inside the semicircular clamping ring, which is easy to operate and has a good clamping effect.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the connecting parts are manually driven to move, thereby driving the semi-circular clamping ring to clamp the threaded steel. However, when actually testing the threaded steel, it is necessary to perform a bending test on the threaded steel. The bending test bends the threaded steel through a hydraulic device, and the cylindrical threaded steel will roll when placed on the testing frame. The clamp in the above-mentioned document is not suitable for clamping the threaded steel during the bending test. Therefore, there is an urgent need in this field to improve the testing clamp for threaded steel to solve the defects of the existing technology. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a detection fixture for threaded steel, which prevents the threaded steel body from rolling when performing a bending test on the threaded steel body, and improves the safety of the threaded steel body during the bending test.
