Description

Technical Field

[0001] The utility model relates to the technical field of steel bar materials, and more specifically, to a steel bar post-fracture elongation detector. Background Art

[0002] The elongation test of steel bars is of great significance to the fields of engineering and materials science. First, it is one of the important indicators for evaluating material strength, which directly affects the durability and safety of the structure. Secondly, standardized testing procedures help ensure that steel bar materials meet the requirements of international and industry standards, thereby achieving quality control and standard compliance. In addition, understanding the elongation of steel bars under extreme conditions helps to optimize structural design, making it more reliable and stable under different load and environmental conditions. Finally, in accident analysis and structural failure analysis, the data of elongation can provide valuable references to guide improvement measures in future design and construction processes.

[0003] After searching, the patent with announcement number CN210108835U discloses an auxiliary device for detecting the elongation after fracture of steel bars. When the steel bars are broken, they are spliced ​​on the surface of the steel bar splicing platform. After the splicing is tight, the movable plate is seamlessly matched with the fixed base through the concave slide groove. According to the size and thickness of the steel bars, the movable plate can slide freely in the concave slide groove, so that the distance between the movable plate and the baffle can be adjusted, so that the tightly spliced ​​steel bars are fixed on the steel bar splicing platform without rolling and instability. Finally, a vernier caliper is used for measurement, which can ensure the accuracy of the detection of the elongation after fracture of the steel bars.

[0004] However, the above equipment has the following defects: although the above equipment can fix the steel bars well and will not cause the steel bars to be sent out of position, the above equipment uses a vernier caliper to measure the broken part of the steel bars. Since the broken part of the steel bars is curved, it is difficult to keep the vernier caliper in the same plane as the steel bars and accurately read the value when measuring. In this case, the measurement error may increase, affecting the accurate evaluation of the elongation of the steel bars after fracture. Utility Model Content
