SWIMMING POOL Russian patent published in 2009 - IPC E04H4/16 

FIELD: construction.

SUBSTANCE: invention is related to construction of swimming pools of individual and public use. Swimming pool comprises leak-tight body and overflow chute arranged along its perimetre, made in the form of composite sections suspended onto pool board as v-shaped in cross section. Sections together with inclined grids create a wedge-like belt, top of which is inverted inside pool body. Composite sections making overflow chute are suspended with gap relative to board of pool body, are tightly adjacent to it with edges of their connecting flanges and are pressed with cantilever frames fixed from top to board hanging over overflow chute with overflow grids laid in them. Overflow chute is separated into two compartments with partitions made in the form of flat profiled plate sections arranged between connecting flanges made of hard polyvinyl chloride, in one of which a submersible electric pump is installed, suction part of which is arranged in one compartment, and its injection part - in the other one. In each of compartments at least in one section along lower part of formed gap there is a filtering material laid in the form of polyurethane foam block laid tight to walls and shelves of connecting flanges, in which filtering material is placed, in bent shelf of back wall of sections above formed gap there is a longitudinal through slot arranged, and along its upper surface there is a bulge formed as wedge-like in cross section, being inverted inside overflow chute. Upper inclined shelf of bulge is equipped with rod-fixators, onto which inclined filtering mesh is placed, and along its lower shelf there are through windows arranged, being closed on internal side with filtering micromeshes of fine water treatment. Front wall of overflow chute has horizontally arranged end shelf, onto which internal edge of overflow rag is laid, on top of which lower framing plank of inclined filtering mesh is placed and pressed from top with lower framing plank bent inside overflow chute till semicircle in cross section of protective-decorative grid fixed with the help of loops to frame hanging over overflow chute. Sections of overflow rag arranged in sections with filtering micromeshes are equipped with brush-lashes arranged along its external edge, which interact with surface of filtering micromeshes inverted to them with any working position of overflow rag.

EFFECT: invention makes it possible to simplify access to filtering material when it is necessary to replace it, provides for self-treatment of surface of filtering micromeshes and possibility of partial placement of filtering material along perimeter of overflow chute.
