In case of an earthquake, the equipment will be displaced or damaged;

[0004] (2) Using angle steel or the like to implant and rigidly connect the equipment foundation and the equipment base feet. Although this method solves the displacement problem of the equipment caused by the earthquake, due to the rigid connection, the self-vibration of the equipment during use is likely to cause damage to the equipment or the angle steel, affecting the seismic effect.
