Description

Technical Field

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

[0002] Earthquake resistance refers to the reference indicator when designing a building. The reference indicator is the intensity of earthquakes that frequently occur in the local area, that is, the destructive power caused by earthquakes. The building is constructed according to the corresponding earthquake resistance standards to withstand earthquakes of a certain intensity and prevent the collapse and damage of the building.

[0003] Common building seismic strength testing devices generally install building panels on the surface of a testing table, install the building panels through plywood, and then hit the building panels through a vibration rod to test the seismic strength of the building panels. However, since building panels are generally subjected to greater pressure under actual circumstances, and existing building seismic strength testing devices generally only hit building panels through a vibration rod, the seismic strength testing devices cannot test the building panels according to actual conditions, and the seismic strength test of the building panels is inaccurate.
