Device preventing collapse of the ceiling

摘要

The present invention relates to a safety device for preventing the collapse of a building ceiling, a plurality of pillars 40 installed perpendicular to the ground and variable in length; A lower plate (20) having a lower surface in contact with the ground and a side surface connected to the lower end of each of the plurality of pillar parts (40); An upper plate 10 having a lower surface facing the upper surface of the lower plate and having a side surface connected to the upper end of each of the plurality of pillar parts; And a vibration measuring unit 50 that is coupled to the lower plate 20 and measures the vibration of the ground, and when the vibration of the ground is sensed, a safety device is operated so that the pillar unit 40 is extended until it reaches the ceiling. It is characterized in that it prevents the collapse and fall of the ceiling and forms a safety zone.
