Description

Technical Field

[0001] This application relates to the technical field of steel bar detection, and particularly to a tensile detection method and system for deformed steel bars. Background Art

[0002] Deformed steel bar is a steel bar with ribs on the surface, also known as ribbed steel bar, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shape of the transverse rib is one of spiral, herringbone, and crescent. It is expressed in millimeters of the nominal diameter. The nominal diameter of the ribbed steel bar is equivalent to the nominal diameter of the plain round steel bar with equal cross-section. The nominal diameter of the steel bar is 8 - 50 millimeters, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 millimeters. The full diameters are 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, 50. The ribbed steel bar mainly bears tensile stress in concrete. Due to the effect of the ribs, the ribbed steel bar has a greater bonding ability with concrete, and thus can better bear the action of external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled, and high-rise building structures. Deformed steel bars have a greater bonding ability with concrete due to the effect of the ribs, and thus can better bear the action of external forces. Steel bars are widely used in various building structures. Especially large, heavy, light thin-walled, and high-rise building structures.

[0003] Since steel bars are widely used in various building structures, it is necessary to detect the quality of steel bars. However, in the prior art, when performing tensile detection on deformed steel bars, the steel bars used for detection are usually broken. At the moment of breaking, the generated noise is between 88 - 101, and vibrations are generated at the moment of breaking, generating noise, which will reduce the electrical components of the inspection equipment, increase the failure rate of the equipment, reduce the service life of the equipment, and at the same time may interfere with other inspection items that require precise weighing.

[0009] Optionally, the step of detecting the target to be detected based on the ultimate strength data to obtain the total elongation of the target to be detected includes:

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, every other embodiment obtained by those skilled in the art without creative efforts belongs to the scope of protection of the present application.

[0025] First, the applicable application scenarios of the present application are introduced. The present application can be applied to the scenario of steel bar detection.

[0026] Through research, it is found that in the prior art, the steel bars for detection are usually broken. At the moment of breaking, the generated noise is between 88 and 101, and vibrations are generated at the moment of breaking, which will reduce the electrical components of the inspection equipment, increase the failure rate of the equipment, reduce the service life of the equipment, and at the same time may cause interference to other inspection items that require precise weighing. At the same time, reducing noise and vibration can also reduce the harm to the physical health of employees.

[0027] Based on this, the embodiments of the present application provide a tensile testing method and system for ribbed steel bars, which set the maximum acting force on the detection target to prevent the detection target from being broken, perform non-breaking experiments to eliminate vibrations, can reduce the failure rate of the equipment, extend the service life of the equipment, shorten the inspection process, and avoid noise.

[0028] As Figure 1 shown in

[0029] S101. Obtain the basic attribute information of the target to be detected, where the basic attribute information includes the strength limit data of the target to be detected;

[0030] Exemplarily, a force diagram of the target to be detected is generated by obtaining the data generated during the detection of the target to be detected;

[0031] S102. Detect the target to be detected based on the ultimate strength data to obtain the total elongation rate of the target to be detected;

[0032] S103. After obtaining the total elongation rate, stop detecting the target to be detected according to a preset attenuation rate of the test force.

[0033] Exemplarily, the maximum acting force on the detection target, that is, the ultimate strength data, is set to prevent the detection target from being broken. By conducting a non-breaking experiment to eliminate vibration, the failure rate of the equipment can be reduced, the service life of the equipment can be extended, the inspection process can be shortened, and noise can be avoided.

[0034] In a possible implementation manner, as Figure 3 shown, the step of detecting the target to be detected based on the ultimate strength data to obtain the total elongation rate of the target to be detected includes:

[0035] Apply a force to the target to be detected with a gradually increasing force until the force is equal to the ultimate strength data;

[0036] When the force is equal to the ultimate strength data, stop increasing the force;

[0037] Based on the force application process to the target to be detected, obtain the total elongation rate of the target to be detected.

[0038] Exemplarily, according to the inspection requirements of the product, on the premise of meeting the inspection requirements, after completing the required inspection indicators, provide a judgment basis (the attenuation rate of the test force after reaching the maximum force) to automatically terminate the test, realize the non-breaking inspection of the anti-seismic ribbed steel bar specimen, and eliminate over-processing.

[0039] In a possible implementation manner, the step of stopping detecting the target to be detected according to a preset attenuation rate of the test force includes:

[0040] Gradually attenuate the force applied to the target to be detected according to a preset attenuation rate of the test force until the force is zero, and stop detecting the target to be detected.

[0041] Vibration has been avoided, and at the same time, noise can be reduced by 30%;

[0042] The inspection process is shortened, and at the same time, the sample discarding action is reduced by 50%;

[0043] Due to conducting a non-breaking test, the cycle is shortened, and the power consumption and the loss of hydraulic oil can be reduced.

[0044] Due to the elimination of vibrations, the failure rate of the equipment can be reduced and the service life of the equipment can be extended.
