Description

Technical Field

[0001] The utility model relates to the technical field of strength detection, and more specifically to a steel bar strength detection device for engineering management. Background Art

[0002] Rebar is an important building material used to connect and strengthen the stability of building structures. It generally has high strength and strong resistance to compression and bending, making the structure of the building more solid and able to effectively withstand strong winds, heavy rains, and damage from external heavy objects, thereby extending the service life of the building. Before the steel bars are used, they need to be tested for certain strength to determine whether the production of this group of steel bars is qualified and whether they meet the requirements for use.

[0003] The shortcomings of the existing technology are: when testing and fixing the strength of the steel bars, the tester needs to manually rotate the wheel so that the screw pushes the clamp to clamp and fix the steel bars. The operation is relatively cumbersome. This operation undoubtedly increases the labor intensity of the tester and slows down the efficiency of testing the steel bars. Moreover, the manual rotation method is very unstable and it is not easy to truly squeeze and fix the steel bars. The steel bars are easily caused to slide during the test, and the test is affected. For this reason, we propose a steel bar strength detection device for engineering management. Utility Model Content
