<p>The present invention relates to a buoyant lifting device for an outdoor structure that is to automatically lift the outdoor structure according to a water level, in which a single or multi-stage lifting column is provided to the outside of a stationary column fixed to a concrete base structure in order for the lifting column to be automatically deployed or telescoped according to the water level, thereby preventing the buoyant lifting device from being exposed to the outside. The buoyant lifting device is installed at four corners inside the structure, so that the device is not exposed to the outside, thereby spoiling the appearance of the structure. Also, it is possible to prevent various alien substances from entering the device not to lower the function of the device.</p> |
