Kit for a prefabricated swimming pool

The invention relates to a kit for prefabricated swimming pools

basin according to the preamble of claim 1.

Swimming pools are exposed to massive lateral pressure, firstly due to the lateral earth pressure when they are sunk into the ground, as is usual, and secondly due to the opposing high outward water pressure. They therefore have to be built very sturdily. Up to now, wall elements made of solid sheet steel have been used, which are attached to a

Side edge L-shaped cross section and on the other side U-15

shaped cross-section, with a U-shaped side edge surrounding the adjacent L-shaped side edge and being screwed to it. These steel profile parts are inserted into a lower base surface and are connected at the top by a U-shaped

Final border held.
20

For ecological reasons, it would be highly desirable to create new products from recycled materials, for example for such prefabricated swimming pools. On the one hand, it was shown that the

most materials because of their shape retention, durability, 25

W itteru &eegr; gs resistance ete. are eliminated. The shape of the wall elements evident in well-known prefabricated swimming pools is, however, completely unsuitable for static reasons. On the other hand, for reasons of handling and cost, the weight

be kept within a certain framework. A special 30

In addition to the relatively low pressure resistance, the problem was the strong tendency to deformation.

The invention is based on the problem of providing a kit for

Prefabricated swimming pool according to the preamble of claim 1 so 35

so that it can be manufactured at least largely from recycled material.

The problem is solved according to the invention by the features of the characterizing part of claim 1. Further embodiments of the invention are presented in the subclaims.

In the claimed kit for prefabricated swimming pools, recycled polyethylene, including impurities, is used as the material for the wall elements. Tests have surprisingly shown that one-piece polyethylene obtained by pressing, such as that which is produced by processing the most common plastic bags, is in principle suitable for this purpose.

In order to achieve suitable stability despite low weight, the wall element is designed as a profile frame part, with a smooth inner side, smooth side edges with a width corresponding to the wall thickness, as well as with reinforcing ribs corresponding to the required static stability between the side walls.

Preferably, border edge ribs can also be provided within the

The frame profile can be shaped in such a way that the required wall openings are created by sawing them out. For an even greater reduction in weight and also for suitable production, the cross-section of the ribs can be narrowed towards the rear. For certain areas such as the parallel fastening points for adjacent

Reinforcements are provided for wall surfaces, for the points of attack of the ejection pins of the wall elements from the pressing tool after production and the like.

To enable stacking, space-saving storage and

^ow to enable pallet transport, are only at the corners of the

For this purpose, vertical studs are provided on the smooth inner sides, which can be pressed into one piece with the wall elements during manufacture. These fit into the corners of the rear profile frame and thus enable stable stacking of many individual

° Wall elements and the connection to a transport pallet.

Two adjacent side walls of adjacent wall elements can be screwed together in a very simple and therefore inexpensive way using screw connection holes.

A standard concrete slab can be used as the base surface, but the same wall elements can also be used within the swimming pool, which are then screwed together with the profile part facing downwards on a stable, level surface, for example on simple lean concrete.

Because of the soft material used, the individual wall elements can also be easily processed later

not only to remove the stacking knobs, but also to 15

Sawing out desired openings, but also to change the height of the wall elements and thus the height of the swimming pool, for example for a children's pool. For this purpose, special cross ribs can be designed so that they can be easily sawn off flush

and can be used as a replacement for the actual upper or lower 20

side wall.

To increase stability, especially when there is no water in the pool, wall supports are provided, the

Front edges can be easily placed between the side walls-25

bearded wall elements and screwed together with them. This is considerably easier than the installation of rear wall supports on the known wall panels, which consist of certain shaped steel profiles and to which

only very cumbersome rear wall supports can be installed 30

can.

It is particularly advantageous that these rear wall supports are also made of the same material, namely polyethylene, which

recovered through recycling. 35

This material only needs to be pressed into sufficiently stable plates of about 2 cm thickness. To fix such

Stable steel sheets with an L-shaped profile can serve as wall supports on the wall elements, which are connected on the one hand to the lower edge area of the wall supports and on the other hand to an external

For example, it can serve to extend a stable base surface such as concrete outwards.

However, the wall supports can also be made entirely of sturdy sheet steel. In this case, the lower fastenings

ment plates can be saved, this can instead be formed in one piece with the wall support, whereby a corresponding downwardly projecting section is simply bent horizontally and screwed to the base surface or connected to it in another way.

is connected.
15

Instead of a relatively large-format wall support, preferably bevelled to the rear or outwards and downwards, a two-part wall support can also be provided, with one end of a wall strip being connected to the side edges of two adjacent wall elements.

is pivotably connected at a fastening point and at the other end, preferably several vertical holes are provided through which a ground anchor can be inserted and is firmly, but under certain circumstances detachably, connected to the stationary support.

In this case, solid surrounding soil can also serve as a support. 25

In order to enable a particularly simple and easy-to-assemble connection of two side walls made of individual wall panels that are perpendicular to each other, a special corner connector can preferably be used, whereby two side walls

can be connected, preferably screwed, to the adjacent side edges of the wall elements that are perpendicular to one another, with the vertical front of the corner connector being arranged at an angle or diagonally to the two side walls that are perpendicular to one another, and thus at an obtuse angle to them, and with stabilizing parts and fastening parts being provided. For stabilization, for example, an upper and a lower cover of the corner connector can be used. For fastening, the

lower cover can be extended outwards or backwards and connected to the fixed support. For further stabilization, supports leading diagonally from top to bottom and outwards can be provided between the upper cover and the extension of the lower cover.

The provision of such a corner connector also simplifies the installation of a sealing film in the fully assembled IQ pool, as the laborious alignment of the corner edges is no longer necessary.

Embodiments of the invention are shown in the drawing. It shows:

Fig. 1 shows schematically a part of the base surface 2, on which two mutually perpendicular base borders 4 are attached. The open side of the U-shaped cross-sectional profile

points upwards. The base surface 2 is extended outwards by extension surfaces 2' beyond the support surface of the base borders 4 in order to be able to serve as a stable support for rear wall supports - not shown in Fig. 1.

The individual wall elements 6 are inserted into the U-shaped profile of the base frame 4 so that they fit closely next to one another and are screwed together in a simple manner using holes 24 in adjacent side walls 9.

As a counter-support to the base border 4, the upper side edges 9 of the individual wall elements 6 are held in place by a common upper end border 8, whose U-shaped cross-section, p-section profile is directed downwards. The base border 4

and the upper border 8 are made of very stable material such as solid steel profile.

Polyethylene plastic bags or the like including certain impurities. Relatively smooth side walls extend from all end edges of the invisible smooth inner side of the wall element generally designated 6

„P- 7, 9 to the rear. Between the long sides 9 and the short sides 7

Reinforcing ribs 10 and 12 are arranged approximately at right angles to each other, depending on the static load. In the wall element shown in Fig. 2, which is approximately 1.20 m high and 50 cm wide, there are two reinforcing ribs 10 and

_{On the} transverse side eight reinforcing ribs 12 are provided. These are made of

For manufacturing reasons and also for weight reasons, the cross-section is tapered towards the rear and slightly less high than the side walls 7, 9, which are about 9 mm high. Excepted from this are an upper transverse reinforcement rib 16 and a

_oc lower transverse reinforcement rib 18, which is exactly flush with the

side walls 7, 9 and may also have other measures that may be necessary to be able to replace the upper or lower side wall 7 if the

the corresponding upper and lower parts are sawn off flush. In this way, lower pool heights can also be easily achieved with the same wall element, for example for non-swimmers' and children's pools.

In the middle of Fig. 2, a circular reinforcing rib 14 is provided, which can be easily sawn out flush inside, in order to accommodate a headlight, for example. Instead, other accessories can also be used.

and drains, edging ribs etc. can be installed, whereby if necessary, the outer rib 14 can be replaced by a different design.

Jg At the four corners towards the smooth - not visible -

On the inside, there is a corner stud 20 that projects inwards perpendicular to the inside and can be snapped into the corners of a wall element located below or above it (shown behind it). This allows for easy stacking, lacing and transport on pallets; after installation, these studs can be easily removed.

Fig. 3 shows the side view of a wall element with side surface 9, which is clamped at the bottom by the base border 4 and at the top by the end border 8. Here, the base border 4 is screwed to the base surface 2.

A rear support plate 26 extends from the side wall 9 to the rear, which can be screwed together with another wall element (omitted in Fig. 3) in one operation. This represents a very simple and yet stable fastening without any special precautions having to be taken on the rear of the wall elements. The support plate 26 is arranged between two meeting end edges of the base border 4 and the upper end border 8.

To save material and simplify handling, the support plate 26 is bevelled downwards and to the rear in an L-shape. It can be attached to the outer extension 2' of the base surface 2 using L-shaped profile strips 28 made of solid material such as sturdy sheet steel. This results in a particularly stable connection, even against lateral earth pressure when there is no water in the swimming pool. Plate fastening points 30 and base fastening points 32 are used for fastening, for example using simple screw connections.

Fig. 4 shows a view of a swimming pool wall from behind showing two adjacent wall elements 6, between which a rear wall support 26 is arranged to increase stability, which is screwed to the extended base surface 2'.

Fig. 5 shows another embodiment of a rear wall support 27, which consists of sturdy sheet steel. In this case, it is possible to make the lower fastening strip 29 with the fixed support, such as an outward extension 2' of the base support 2 for the swimming pool, in one piece with the wall support itself. In this case, only a section of the wall support that initially projects downwards is angled horizontally.

Fig. 6 shows a third embodiment of a wall support, which consists of two parts. Here, one end 42 of a wall strip 40 is fastened, in particular screwed, to the horizontal fastening opening 24 of a vertical side wall 9 of a wall element 6 or at the same time to the two adjacent side walls 9 of two adjacent wall elements 6. At the other end 44 of the wall strip 40, three essentially vertical holes 46 are provided. A pin like a ground anchor 48 is passed through one of these holes, which is firmly, but detachably if necessary, connected to the support, which in the embodiment of Fig. 6 is the ground 50. The provision of several holes 46 enables adaptation to different structural conditions.

Generally speaking, it should be mentioned, which applies to all three examples of support plates, that these can also be designed to be easily removable, whereby the fastening to the wall elements does not have to be

g two adjacent side walls 9, but only at

an inner wall of a single one of these side walls 9. In this case, an easier subsequent removal is possible, namely after final assembly of the entire kit and, if necessary, after further usual measures, such as the production of an upper circumferential

jQ Concrete border, possibly also the filling of water

Etc.

Fig. 7 shows a top view of a corner connector, generally designated 60, between two wall elements 6 that are adjacent to one another at right angles, the side walls 9 of which are connected, preferably screwed, to the parallel and adjacent side walls 66, 68 of the corner connector 60. The corner connector 60 has an upper cover 61 and a lower cover 63 that is not visible in the top view of Fig. 7, the latter having a rear extension 70 to the rear or outside. This extension 70 is used for fastening to a stationary support - not shown - via corresponding screw holes 72. Furthermore, Figure 7 shows two lateral stabilizing strips 74 that run from below and behind diagonally upwards to the side walls of the upper cover 61.

Fig. 8 shows a vertical section along the line 8-8 of Fig. 7. Here, additional horizontal holes 76 are visible on the side walls of the corner connector 60, which are aligned with the corresponding horizontal openings 24 on the side walls 9 of the wall elements 6 in order to enable a screw connection with them.
