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

FIELD: construction industry.

SUBSTANCE: swimming pool consists of a reservoir made of boards connected by means of cross-shaped lock with the bars installed outside, each side of which rests on support posts installed in its centre. Side of V-shaped grid with filtering gauze installed thereon faces the overflow chute, and is inward-bent radially in its cross section of the shape, and is equipped with two planks arranged longitudinally, upper one of which passes smoothly from inward-bent part of the grid to horizontal flange located thereabove. On the flange there installed is a decorative panel hinged by means of joint-hinges to flooring around swimming pool. Lower plank is made of two flanges connected to each other at right angle; one of flanges passes smoothly from bent part of the grid to horizontal flange resting on the overflow chute bottom through inserts. The other flange is located at a distance from swimming pool reservoir wall so that the edge of overflow covering that is located on filtering material and overhangs below overflow chute bottom can be pressed to its side surface. Filtering material is located on overflow chute bottom through drain gaskets with drain channels located transversally and connected to swimming-pool reservoir on one side, and to longitudinal drain channel along rear wall of overflow chute on the other side. Overflow chute pipeline located in its corner part is connected to suction branch pipe of electric pump the delivery branch pipe of which is connected to swimming pool reservoir. Reservoir walls and overflow chute rest through vertical support bars and crossbars connected thereto on protrusions of foundation of heat-insulated structure, which are arranged uniformly along the perimeter of swimming pool reservoir. In gaps between support bars there laid is heat-insulating material, e.g. block foamed plastics, and gap between foamed plastics and foundation walls is filled with loose heat-insulating material, e.g. expanded clay.

EFFECT: improving water purification degree under conditions when swimming pool is used not often or occasionally.
