QUICK-ERECTED FLOATING STRUCTURE (VERSIONS) Russian patent published in 2015 - IPC B63B35/44 E04H3/00 

FIELD: construction.

SUBSTANCE: group of inventions relates to construction and can be used for quick erection of floating structures. A structure is built on a flat ground filled with concrete and can have the shape of a sphere, a semi-sphere or any other shape. As per the first version, the structure is made from a solid soft formwork, includes a cavity either form a solid or a woven polypropylene or other strong fabric, to which liquid foamed plastic is added under pressure or air is pumped-in. Canvases are attached to each other with capronic binders, polypropylene yarn or a packing belt. Between the canvases there laid inside the cavity is flexible capronic reinforcement net, through which capronic binders, polypropylene yarn or packing belt pass. The filled structure is coated from outside with layers of liquid fibre glass or carbon-filled plastic. The structure is attached with loops to posts buried into earth. As per the second version, walls and the roof of the structure are made of a metal frame, onto which a thin layer of polypropylene material or other strong material treated with liquid fibre glass or carbon-filled plastic is applied. As per the first version, the structure foundation is made of a soft formwork.

EFFECT: increasing strength and flotation ability of a structure.
