Abstract

Prefabricated element for the construction of an overflow channel of swimming pools, characterized in that the prefabricated element (1) consists of a single U-shaped piece that consists of cellular Plastic is made and in its width (B) and height (H) the bricks used for the pool equivalent.

Description

The The invention relates to a precast element for the construction an overflow channel of swimming pools, especially public ones Institutions.

For swimming pools in public baths, an overflow channel is mandatory for hygienic reasons. This serves the continuous water cycle for the purpose of cleaning the water from pathogens, dirt, hair, leaves or the like. In order to sufficiently ensure this function, the entire basin edge must have the same height. According to DIN 19643-1 Only very small deviations are allowed.

To ensure these height tolerances, it has already been proposed ( DE 296 04 536 U1 ) that the channel body is height adjustable after installation. This solution is very expensive both in the production, as well as in the installation.

Known is the production of gutter elements as precast concrete part, which is lined with sealing film ( DE 196 30 841 A1 respectively. DE 296 18 529 U1 ). A disadvantage is the high weight of the precast concrete parts, which makes the laying work, especially the exact leveling of the basin edge, difficult.

It has also been proposed ( DE 199 06 507 A1 respectively. 298 02 829 U1 ) to produce an overflow channel of plastic moldings. For the parts to be stable, struts and crossbars must be provided. For leveling screws are also used here. This part is quite complicated and therefore costly to manufacture and to assemble. A simpler construction of an overflow trough finished part is from the utility model DE 203 17 659 U1 known. This part, which is made of flexible polyolefins (FPO), is placed on the edge of the pool and welded to the plastic waterproofing membrane of the pool. In order to achieve an exact same height of the entire overflow edge, the edge of the pool must be made very accurately, which makes the construction work before significant requirements. Another disadvantage is the poor thermal insulation properties of this overflow trough finished part. For energy saving reasons, the walls of swimming pools are now made of styrofoam bricks, which are filled with concrete for reasons of strength, because such a good thermal insulation of the pool wall is created. This is reduced by an overflow channel made of FPO.

The Problem to be solved by the invention is a prefabricated part, the construction of an overflow channel of Swimming pool with a very accurate height of the overflow edge over allows the entire pelvic area in a simple way, even is inexpensive and has good thermal insulation properties having.

The Problem is inventively by a precast element solved that from a single U-shaped piece which is made of cellular plastic and in its Width and height dimensions for the swimming pool used bricks corresponds.

This Finished part is extremely light, can be made to measure on site tailored and easy to be laid. Several parts are glued together and thus provide a watertight joint. The attachment on the edge of the pool is expedient in one Mortar bed. Due to the low weight leaves easily reach a very precise height compensation. Zelliger plastic has very good thermal insulation properties on and thus complements particular pool walls made of styrofoam stones in an ideal way. Further advantages arise by the subclaims.

So the finished part is expediently made of rigid polyurethane foam produced. This has a high strength.

Farther it is expedient, the water-side surface of the finished part additionally with a waterproof layer to provide. The coating can be either plastic film or with PVC or FPO coated sheet, depending on the choice of lining of the swimming pool.

For Bathrooms with tiled flooring will increase the height the prefabricated element expedient to the construction height the tiles used increased to stumbling edges to avoid. Conveniently, the U-shaped Gutter body to cover the gutter support edges for a grid on which a slight inclination of the grate towards give the water surface.

Farther it makes sense, the waterside leg of the overflow trough top up to prevent injury to pool users.

One improved drainage through the gutter results when the Channel bottom not flat, but concave shaped, because the overflow water is not can stay in the margins, but always to the middle running.

The Invention will be described below with reference to an embodiment explained in more detail.

It demonstrate:

1 the page top view on a precast part element with an angular groove

2 the section through a precast with concave gutter, the water-side surface is provided with a foil sheet and

3 a portion of a section through a pool wall, which is provided with an overflow channel.

In 1 is the profile of a finished part according to the invention 1 shown, which is suitably made of rigid polyurethane foam. Width B and height H are chosen according to the dimensions of the bricks used for the swimming pool. Due to thermal reasons Styroporstones are increasingly used, which are filled with concrete. For that will be. the dimensions B = 240 mm or 300 mm and H = 130 to 300 mm. Other dimensions are possible.

The length of the precast element 1 can be chosen as desired in the production, but can be large due to the low weight of the hard foam. Sensible are lengths of two meters and more. As part of the assembly, they can be easily shortened to the required smaller installation lengths. Several precast elements 1 are glued together when laying, so that no leaks are present.

Due to the low weight, the precast elements can be 1 easy to lay and align in a soft mortar bed very well at the same height.

The gutter 4 serves for receiving and discharging the overflowing from the left of the pool water.

To cover the gutter is usually a cover grate. There are requirements for that 3 and 5 and stop edges 6a and 6b available. The right edition 5 is slightly higher than the left pad 3 , This gives the cover grate a slight inclination in the direction of the swimming pool.

The side wall 7 of the precast element 1 forms after laying a part of the pelvic wall. The stop edge 8th serves to cleanly limit a fleece attached to the pool wall.

The left leg of the precast element 1 ends up in a grip head 2 , For the grip head in public baths a round shape is prescribed. Private users of a swimming pool can, depending on their taste, also desire a slightly angular shape (eg that of an octagon).

The gutter 4 can, as in 2 shown a concave shape 4a have, whereby the water flow is improved. In 2 is also shown that the overflow water exposed surface of the precast element 1 with a foil sheet 9 covered with both ends 10a and 10b in the precast element 1 is anchored. This results in a higher density. The foil sheet 9 is either postponed or during the manufacture of the precast element 1 Strongly sticking during chemical reaction, associated with this.

The finished construction of a pool edge with overflow channel is off 3 seen. In the masonry 12 The swimming pool wall is an installation niche for a precast element available. In this niche is the precast element 1 on a mortar bed 11 set. The soft mortar when laying allows a good leveling of the handle head 2 which forms the overflow edge of the swimming pool. This will ensure that the pool water will overflow evenly along its entire circumference.

A fleece 14 on the pool wall 13 Applied is similar to unevenness of the pelvic wall 13 and serves as protection for the swimming pool film 15 , The latter is around the grip head 2 placed around, creating a continuous closed surface.

The height H of the precast element 1 is chosen so that after laying the tiles 15 a continuous tread without tripping arises.
