PLATFORM Russian patent published in 2021 - IPC B63B35/44 E02B17/00 

FIELD: floating platforms.

SUBSTANCE: invention relates to floating platforms designed for special purposes, namely pontoons, floating docks, rafts and other floating structures, and consisting of modules, the hulls of which are made of plastic material. The platform contains buoyancy modules connected by at least one fastening element, each consisting of a hollow plastic body with lugs for fastening elements made at four levels, formed by at least two lateral edges with at least one vertical protrusion on one of them and with at least one vertical protrusion on the other, at least two lateral faces with at least one vertical depression on one of them and with at least one vertical depression on the other, corresponding vertical ledge, top edge and bottom. Each vertical protrusion and each vertical depression are formed by three walls, while in cross-section each vertical protrusion and each corresponding vertical depression are made in the form of an acute-angled trapezoid, the larger base of which is located in the plane corresponding to the side face of the body, the angle α of inclination of each side of the trapezoid to the smaller base is selected from the ratio 90° < α ≤ 110°, and the ratios of the length L1 of the smaller base of the trapezoid and the distance L2 from the larger base of the trapezoid to the base of the nearby eye to the thickness b of the hollow body are selected from the ratio L1/b≤15 and L2/b≤15.

EFFECT: increasing reliability while ensuring manufacturability of manufacturing each module by eliminating its damage when it leaves the mold, facilitating the assembly of modules among themselves, ensuring transverse strength of the trapezoidal profile of each protrusion and corresponding depression, affecting the unloading of the lugs, and eliminating loss of stability of the platform walls during transverse compressive loads.
