Description

Technical Field

[0001] The utility model relates to the field of building structure safety detection, in particular to a building structure seismic resistance detection device. Background Art

[0002] Earthquakes, as natural disasters, pose a serious threat to human safety and property. Especially in earthquake-prone areas, the seismic performance of buildings is directly related to the safety of people and property. Therefore, conducting seismic testing on buildings to ensure they can withstand potential earthquake shocks is a crucial measure to reduce losses from earthquake disasters.

[0003] Traditional methods for testing the seismic resistance of buildings primarily include static and dynamic testing. Static testing typically assesses a building's load-bearing capacity by applying static loads, while dynamic testing simulates earthquake waves to stimulate the building and observe its response. These methods often require specialized equipment and personnel, are complex, and are time-consuming and labor-intensive.

[0004] Currently, when inspecting the main supporting structure of a building, in addition to observing the appearance, ultrasonic testing is also used to detect the interior. Ultrasonic testing is an important non-destructive testing method in construction projects and can be used to detect the safety, stability and quality of building structures.

[0005] Currently, most inspections involve inspectors using handheld ultrasonic detectors to conduct all-round inspections of the building's main support columns or beams. This handheld inspection method not only places high workload on inspectors but also makes it easy for areas to be missed. Utility Model Content
