Description

Technical Field

[0001] The invention relates to an elongation detection system and a use method thereof, in particular to a steel bar post-fracture elongation detection system and a use method thereof, belonging to the technical field of steel bar detection. Background Art

[0002] Each batch of steel bars should have a factory inspection certificate that meets the standards, and a test report on mechanical properties and chemical composition. Its various indicators, data, batch size, instructions, visas and stamps should be complete, accurate and true.

[0003] Each batch should consist of steel bars of the same brand, same furnace number, same specification and same delivery status.

[0004] The construction unit's laboratory should conduct inspection tests on the incoming steel bars in accordance with relevant regulations, and provide a "Rebar Test and Identification Report" as the basis for using the steel bars. When the inspection test results are inconsistent with the original certificate and test report, re-sampling and re-testing should be carried out, and the cause should be found out and the treatment method should be determined before the steel bars can be used.

[0005] There shall be no cracks, scars or folds on the surface of the steel bars. If any abnormal phenomena occur during the processing and installation of steel bars that have passed the inspection and test, the chemical composition analysis should be redone for identification. If the test fails, the steel bars should be stopped from use immediately.

[0006] Therefore, it is particularly important to test the elongation of steel bars. The traditional method is to send the broken steel bars to a designated laboratory or have workers make simple estimates, which will waste a lot of time and even delay the construction period. If manual predictions are made using rulers, a lot of time will also be wasted and the accuracy is not high.

[0007] Therefore, it is urgent to improve the elongation of steel bars to solve the above-mentioned problems. Summary of the invention

[0008] The purpose of the present invention is to provide a steel bar elongation detection system and a method for using the same. The detection system provided by the present invention has a simple structure, a small size, and is flexible to use. It does not require going back and forth to the laboratory to wait for the test results, and it can also avoid errors caused by manual detection, thereby greatly improving the convenience and accuracy of use.

[0009] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0010] A steel bar elongation detection system comprises an electric control box and a brake base fixed on the electric control box, wherein a symmetrically distributed supporting structure is slidably arranged on the brake base, wherein the supporting structure comprises a transverse sliding structure and a longitudinal sliding structure, and the transverse sliding structure is slidably arranged on the upper side of the longitudinal sliding structure;

[0011] A longitudinal detection structure and a plurality of third infrared detectors are arranged between the two transverse sliding structures, one end of the longitudinal detection structure is fixedly connected to the electric control box through a second telescopic rod, and the longitudinal detection structure is used to test the cross-sectional area of ​​the steel bar;

[0012] A storage battery is fixedly arranged inside the electric control box, and a central processing chip is connected to the storage battery. The central processing chip establishes communication connections with the longitudinal detection structure and the third infrared detector respectively.

[0013] Through the above technical scheme, the construction unit laboratory should carry out inspection tests on the transported steel bars according to relevant regulations, and put forward a "steel bar test identification report" as the basis for using the steel bars. When the inspection test results are inconsistent with the original certificate and test report, the steel bars should be re-sampled and re-tested, and the reasons should be found out and the treatment methods should be determined before they can be used. Therefore, it is necessary to conduct effective tests on the broken steel bars. The traditional method is to send the broken steel bars to a designated laboratory or have workers make simple estimates, which will waste a lot of time and even delay the construction period. There are manual predictions using rulers and compasses, which also waste a lot of time and the accuracy is not high. The detection system provided by the present invention has a simple structure, a small size, and is flexible to use. It does not need to go back and forth to the laboratory to wait for the test results, and it can also avoid errors caused by manual detection, thereby greatly improving the convenience and accuracy of use;

[0014] The device can be directly used for direct measurement. The undamaged steel bar is directly fixed on the brake base, and the third infrared detector is used to directly measure it. Then the steel bar at the fracture is moved between the two transverse sliding structures, and the third infrared detector is used to measure the fractured steel bar. The measurement is valid regardless of the fracture position. The elongation is calculated by reading the first and second measurement values.

[0015] In order to avoid the fracture being on the same horizontal axis, the two broken steel bars can be fixed on two transverse sliding structures respectively. The specific method is as follows:

[0016] Before detection, the original gauge length L0 is subdivided into N equal parts by the third infrared detector;

[0017] After the longitudinal sliding structure separates the broken steel bars, the short section of the steel bars is inspected by the longitudinal inspection structure 7 and marked with X, and the long section of the steel bars is inspected and marked with Y;

[0018] Then use the third infrared detector to divide X and Y equally, with the number of grids being n;

[0019] If Nn is an even number, measure the distance between X and Y, and measure the distance from Y to the Z mark which is 1 / 2 (Nn) divisions away;

[0020] Then the elongation after breaking is A=(XY+2YZ-L0) / L0*100%;

[0021] If Nn is an odd number, measure the distance between X and Y, and measure the distance from Y to the distance between Z' and Z'' marks which are 1 / 2 (N-n+1) divisions;

[0022] Then the elongation after breaking A=(XY+YZ'+YZ''-L0) / L0*100%;

[0023] The calculation formula of elongation obtained from the above is:

[0024] δ = (L1-L0) / L0*100%;

[0025] Among them, δ is the elongation, L1 is the original gauge length of the steel bar, and L0 is the gauge length after the steel bar is broken;

During the movement of the first telescopic rod, the output end of the first telescopic rod is fixedly connected to the braking protrusion, which can promote the longitudinal movement of the longitudinal sliding structure. At the same time, the longitudinal sliding block on the longitudinal sliding structure can slide inside the connecting plate and the limit plate groove to ensure the stability of the transmission of the longitudinal sliding structure. The structure is simple, easy to use, easy to measure, and small in size for easy carrying and transportation, which greatly improves the convenience of use.

Then, the size of the fractured part can be compared with the original size to detect the ductility of the steel bar.

When the inspection test results are inconsistent with the original certificates and test reports, the steel bars should be re-sampled, re-tested, and re-judged, and the reasons should be found out and the treatment methods should be determined before they can be used. Therefore, it is necessary to conduct effective tests on the broken steel bars. The traditional method is to send the broken steel bars to a designated laboratory or have workers make simple estimates, which will waste a lot of time and even delay the construction period. There are manual predictions using rulers and compasses, which also waste a lot of time and the accuracy is not high.
