Description

  The present invention relates to a building buoyancy imparting device for preventing submergence or damage of a building due to a tsunami or flood, and a building using the same.

  Conventionally, when a tsunami caused by an earthquake or a flood due to heavy rain occurs, priority is given to protecting human lives, such as evacuating to a hill. However, there are cases where evacuation is not in time and the building is left behind and suffers damage. Even if you can evacuate safely, you may suffer damage to the building itself, such as submergence or damage to the house.

  Therefore, conventionally, a building is built on a trolley type floating body, and when the floating body is immersed in water due to a tsunami or flood, the building is floated on the water surface by the buoyancy of the floating body (for example, patents) Reference 1, 2 or 3).

  In this way, in the case of building a building on a floating body, even if a large-scale tsunami or flood occurs, the building can be floated on the water surface by the floating body. In addition to being able to increase, it can also prevent the building itself from being submerged or damaged.
