Reinforcing steel bar bending strength detection device

Abstract

The invention discloses a reinforcing steel bar bending strength detection device which comprises a supporting part. A workbench is fixedly connected to the top of the supporting part; a first connecting rod is fixedly connected to the interior of the supporting part; and a servo motor is fixedly connected to the top of the first connecting rod. According to the invention, the bending resistance of the reinforcing steel bar is tested in a lateral extrusion bending manner; with a fixation device, the reinforcing steel bar body is protected from being clamped into a push plate in testing and oneside of the reinforcing steel bar body can be limited; after setting of first limiting holes and second limiting holes in different positions, adaptability to reinforcing steel bar bodies with different lengths can be improved; the push plate is prevented from displacement in the testing process because of mutual limiting between a fixed thread sleeve and a pushing device, so that the high detection accuracy is ensured; and with a set sealing cover, the reinforcing steel bar is prevented from being broken effectively in testing and thus the operation is protected from being injured by any mistake.

Description

technical field [0001] The invention relates to the technical field of construction detection, in particular to a device for detecting the bending strength of steel bars. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. [0003] The main function of steel bars in construction is to stand up and connect and support, and the bending resistance of steel bars for praying support is particularly important. However, most of the bending resistance tests in the prior art place steel bars in parallel, and then place them in the The top of it is bent by a hydraulic press to read the corresponding numerical pressure, but the cross-section of the steel bar is mostly circular. When the above method is used to detect, it is easy to cause the steel bar to rotate, resulting in inaccurate ...

[0003] The main function of steel bars in construction is to stand up and connect and support, and the bending resistance of steel bars for praying support is particularly important. However, most of the bending resistance tests in the prior art place steel bars in parallel, and then place them in the The top of it is bent by a hydraulic press to read the corresponding numerical pressure, but the cross-section of the steel bar is mostly circular. When the above method is used to detect, it is easy to cause the steel bar to rotate, resulting in inaccurate detection of the steel bar or the failure of the hydraulic machine. The misalignment between the hydraulic head and the steel bar may cause the steel bar to break during the steel bar test and affect the operator. Therefore, we propose a steel bar bending strength detection device
