Description

PREFABRICATED MODULAR ELEMENTS FOR POOL CONSTRUCTION
AND MANUFACTURING METHOD (LOST FORMWORK)
The invention relates to modular prefabricated elements intended for the economical construction of swimming pools either of the polyester concrete type or of the "liner" type, and the method for their implementation.

In order to allow rapid and economical construction of liner or more conventional swimming pools with a coating of glass paste or mosaics, the walls of these can be made by assembling identical prefabricated panels together. , cooperating with a chain linked to that of the support slab of the swimming pool.

These prefabricated panels can for example be of the type described in the patent application FRANCE No 82 24 031
If this type of panel provides a solution representing considerable progress in the speed of implementation of the pool, their shape remains relatively complex and therefore their relatively high manufacturing cost.

Furthermore, their shape does not allow them to be made from any material.

Another drawback of this type of panel is that it has a lateral assembly system requiring a relatively long implementation time.

In order to overcome these various drawbacks, we had the idea of making a prefabricated modular panel having the following characteristics - Possibility of using vertical chaining to link with chaining
of the pool floor slab - A fast side assembly system that does not require adjustment
precise prior - Possibility of high horizontal chaining - Possibility of mass production by a rapid process (extrusion /
injection etc ...) in a wide variety of materials (ABS resin, po
lyethylene etc ...) Possibility of obtaining different forms of swimming pools with a single type
of prefabricated nodular panel, by modifying the shape of the
connecting piece between panels.

According to a first characteristic of the modular panels according to the invention, these comprise two opposite rectangular parallel flat surfaces, separated by one or more spacers, also delimiting several cavities between these two surfaces.

The parallelepiped volume thus defined between the two parallel rectangular surfaces is completed by two external spacers comprising over their entire length the fixing system provided for joining the modular panels in pairs.

According to another characteristic of the modular panel according to the invention, the end or interior spacers in the modular panel are mutually parallel and perpendicular to the main rectangular exterior surfaces.

According to another characteristic of the modular element according to the invention, the tops of the end or interior spacers are notched in
V or in a semicircle or in any other form which can be produced simply, so as to allow the passage of an upper horizontal chaining intended to collaborate with the chaining passing vertically between the spacers.

According to another additional characteristic of the modular panel according to the invention, the inter-element fixing systems can for example be of the following types - Tenon and mortise (glued or keyed) - Male and female dovetails - Female dovetails linked by a room with two tails
male dovetails.

The devices previously listed are given by way of example of a preferred embodiment and other systems could be used within the framework of the invention.

It is understood that these systems, located on the outer spacers, can be found over their entire length, the necessary surfaces having generatrices parallel to those of the spacers and rectangular planar surfaces, which allows manufacturing by extrusion.

According to another additional characteristic of the invention, the tenons and mortises of rectangular section can be drilled perpendicularly, at determined intervals, so as to allow the passage of pins or keys to reinforce the quality of the assembly.

According to another characteristic of the invention, when the modular panels are produced with female dovetails only, the assembly is done by means of a part comprising two opposite male dovetails. This piece will preferably have the same height as the modular elements.

According to another characteristic of the invention, the two male dovetails may be offset angularly so that the part which supports them has a section, for example triangular. It is understood that this arrangement makes it possible to angularly offset the modular elements thus connected to one another, and to produce various forms of swimming pools and not only rectangular, the flat faces of the intermediate piece resting on the flat faces of the two neighboring modular elements. .

The accompanying drawings, given by way of nonlimiting examples, will make it possible to better understand the characteristics of the panels formed of modular elements according to the invention.

FIG. 1 shows a modular element (1) according to the invention.

This comprises two opposite flat, rectangular and parallel faces (2). The walls (3) are connected by spacers (4) whose generatrices are parallel to those of the flat surfaces (2). The volume thus delimited by these flat surfaces (2) and the end spacers (5) is parallelepiped. The spacers (4) and (5) and the walls (3) delimit cavities (6) opening at the two upper and lower ends of the modular element (1).

In the example shown, an end spacer (5) has a dovetail notch (7) over its entire length, while the other end spacer has a lug (8) over its entire length. corresponding section. It is understood that, when two modular elements (11) are joined, they can be secured by means of the notch (7) and the tenon (8).

The upper ends of the spacers (4) and (5) have a notch shape (9), shown in the example above in the form of a V, so as to delimit a horizontal empty space between the walls (2) to their upper part.

There is shown in Figure 2 a top view of two modular elements (1) each comprising a stud (w) and a notch (7) of rectangular section. According to an additional characteristic, this tenon (q) and this mortise (7) can be linked or assembled by a pin (10).

FIG. 3 shows a top view of two modular elements (1) each comprising a mortise (;) and a tenon (R) in dovetail.

FIG. 4 shows two modular elements (1) each comprising two dovetail mortises (7) in their end spacers (5).

An intermediate piece (11) carrying two male dovetail sections (8) is fixed in the two adjoining mortises (7) to secure them.

The two modular elements (1) are thus fixed side by side.

FIG. 5 shows two modular elements (1) each comprising two dovetail mortises (7) in their end spacers (5) and assembled by an intermediate piece (12) whose opposite faces (13) form an angle (14) between them.

It is understood that the two consecutive modular elements (1) thus assembled form an angle (14) between them.

The advantages of the modular elements (1) produced according to the invention are thus better understood.

These modular elements having all their parallel generators can be produced by extrusion, which makes it possible to lower the production cost considerably. Furthermore, all the modular elements (1) can be identical, only the connecting pieces (12) can have particular shapes.

- No prior positioning is necessary before putting them in place
place - Due to their manufacturing process, they can be made
in any material compatible with the manufacturing process
cation by extrusion.
