Description

School is with earthquake table of moving away to avoid possible earthquakes

Technical Field

The utility model belongs to the technical field of teaching equipment, and particularly relates to a seismic isolation table for schools.

Background

Earthquake, also called earthquake and earth vibration, is a natural phenomenon that the earth's crust will generate earthquake waves during the vibration caused by the process of releasing energy rapidly. The mutual extrusion and collision between the plates on the earth cause the dislocation and the fracture of the plate edges and the plate interiors, which is the main reason for causing earthquakes.

At present, schools in plate junction areas and areas with frequent geological activities are mostly provided with desks with high structural strength for students to use, so that concrete structures for people who cannot get rid of the schools in time to avoid falling are improved when an earthquake occurs, and the survival rate of the trapped people is further improved.

But at present, as is well known, the first task after the earthquake happens is to confirm whether aftershock still remains and confirm the stranded personnel position rapidly at the same time, appoint the search and rescue route and divide the search and rescue scope again, but table of moving away to avoid possible earthquakes among the prior art, its structure is comparatively simple, and the function is single, only possesses higher structural strength and simple study additional function, and can't improve the survival rate of the student after stranded for search and rescue personnel are difficult to confirm the stranded position of stranded personnel, and the practicality is lower.
