System permitting the coating fibres in the tanks of the masonry work of orthogonal (swimming pools, pits, tanks) with the aid of a simple tarpaulin, without any shaping, without a paper-, without solder or adhesive bonding

摘要

The system comprises a recess created over the whole height, in the internal masonry corners, which suitable recess will contain the folds of the fabric caused by putting it into shape. The design of the recess also makes it possible to slide a key over the whole height. This key holds the folds in position, provides finishing and an attractive appearance, and nevertheless allows the fabric to come out of its housing under the effect of the tensions due to the ageing of the plastics. The system solves all the dimensional problems known with this type of lining, generally preshaped to size. There is no longer a manufacturer involved and therefore no more disputes regarding dimensions between him and the site. It also solves, by permanent adaptation, the tensions caused by the contractions with time of the plastic sheets. Durability and safety are improved. The invention is used commonly for swimming pools. It is employed for water reserves, septic tanks or catch pits. It may be employed for all types of liquids by matching the sheet to the nature of the contents. IMAGE
