Description

Technical Field

[0001] The utility model relates to the technical field of steel structure stress detection, in particular to a steel structure stress detection device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. During the installation, unloading, modification, reinforcement, concrete pouring and other processes of the steel structure, its stress will change accordingly. The technical means of using testing instruments to detect the stress changes of the stressed steel structure is used for technical personnel to compare with the control value to ensure the safety of construction.

[0003] According to a publicly disclosed steel structure stress detection device (publication number: CN220751429U), in the above application, the steel structure detection part is placed between the two clamping plates on the clamp seat, and the two clamping screws are rotated respectively to push the two clamping plates and the pad to buffer the clamping detection part from both sides along the first guide rod, and fix it on the clamp seat on the bottom plate. Although this method fixes the workpiece, in the process of fixing, it is judged by manual judgment whether the workpiece is fixed tightly, and the manual judgment method will have a certain deviation, which can easily cause the steel structure to shift or slip during the detection process, thereby causing deviation in the detection result. At the same time, in the process of steel structure detection, it is necessary to apply a large force or pressure to the steel structure to be tested. Some defective steel structures will break and splash due to the large pressure, thereby causing safety hazards around the detection platform. To address this problem, we have proposed a steel structure stress detection device. Utility Model Content

The stress sensor 6 measures the stress on the steel structure and monitors the stress of the structure in real time to determine the safety of the structure. There will be a physical contact surface between the stress sensor 6 and the structure. When the steel structure is subjected to force, the stress sensor 6 will sense the stress changes on the structure and convert these changes into electrical signal output. The output signal of the stress sensor 6 is usually amplified and processed for better analysis and detection. After the detection is completed, the hydraulic rod 891 is driven to drive the moving block 892 to move to the left, and the latch tooth 895 can resist the limit rod 83 and fold under the support of the torsion spring 84, thereby releasing the fixation of the steel structure. The cross bar 93 is no longer resisted, and the protective plate 96 can move downward under the support of the telescopic rod 97, and no longer blocks the detection platform 7, so as to facilitate the operator to remove the steel structure.
