Description

TECHNICAL FIELD

[0001] The utility model relates to steel performance detection technical field, concretely relates to a stress performance detection equipment of building steel. BACKGROUND

[0002] In the field of construction, steel is an indispensable structural material, and its stress performance is decisive for ensuring the safety, stability and durability of buildings. Therefore, accurate and comprehensive detection of the stress performance of building steel is a key link to ensure construction quality and safety. Traditionally, the stress performance of building steel is mainly detected by mechanical testing methods such as tensile test and bending test. These methods can intuitively reflect some basic mechanical properties of steel to a certain extent, but also expose a series of limitations, including complex testing process, incomplete data collection, limited testing precision and strong subjectivity in result interpretation.

[0003] For example, a building steel stress performance detection device (application number: 202122756583.9) disclosed in a Chinese patent improves detection accuracy by integrating a resistance strain sensor, which is undoubtedly a major manifestation of technological progress. The resistance strain sensor can accurately measure the slight strain of steel during the stress process, providing more detailed data support for the evaluation of steel mechanical properties. However, despite the improvement in accuracy, there are still deficiencies. Specifically, the device still relies on manual visual observation of the bending of the steel plate during the detection process, which often makes it difficult to accurately capture the slight bending of the steel plate, thereby affecting the accuracy and reliability of the detection

[0004] In view of this, the utility model is improved and optimized based on the existing steel performance detection equipment, and a building steel stress performance detection device is developed. UTILITY MODEL CONTENTS
