METHOD FOR CONSTRUCTING POOLS AND PROVISIONAL FRAMEWORK
IMPLEMENTATION IN SUCH A METHOD FIELD OF APPLICATION OF THE INVENTION
The present invention relates to the field of swimming pools and more particularly to a new technique for constructing swimming pool walls.

DESCRIPTION OF THE PRIOR ART
To date, swimming pools are divided into two different categories: so-called above-ground pools and so-called underground pools. The field of the present invention is at the level of the construction of in-ground pools in which three modes of construction are distinguished.

 The first construction method concerns swimming pools made from a monobloc shell which, obtained from a molding material such as polyester resin or epoxy resin reinforced with fiberglass, is placed in an excavation dug in the size of the hull with a margin of thirty centimeters around. The hard and smooth coating or "gel coat" is already applied to the bottom and the walls of the shell, in the workshop when the latter is manufactured. These so-called monohull swimming pools, however, have drawbacks, in particular in terms of their size which is deliberately limited due to the size of the mold used for the manufacture of the hull and of the means of transport necessary for conveying the same hull in situ. On the other hand, in order to avoid any risk of deformation of the one-piece structure of the hull, it is essential that the excavation has a surface condition free of any defect in order to ensure reception of the hull in good conditions. It follows on the part of consumers, an increasingly large decommissioning for the installation of swimming pools designed according to this first method of construction.

 The second method of construction concerns swimming pools with a shotcrete, masonry or poured concrete structure. For

<Desc / Clms Page number 2>

 create a sprayed concrete swimming pool structure allowing any possible form of construction and with any type of coating, a cement / sand / gravel / water mixture is forcefully pulsed at the outlet of the nozzle of a cannon, to be applied to the walls of the excavation previously lined with a wire mesh ensuring the maintenance and reinforcement of the mixture thus applied.

 To make a masonry concrete swimming pool structure, the walls are erected from concrete blocks mounted between posts and then chained together with reinforced concrete. A mortar will then be floated on the inside of the basin to perfect the finish and receive any type of shape with a "liner" or reinforced PVC coating.

 To make a swimming pool structure in poured concrete, the walls are erected using a formwork obtained from a wire mesh, traditionally supported formwork panels, or even concrete or polystyrene concrete blocks in which concrete is poured. .

So once the formwork is done, just pour the concrete, then run a trowel or smoothing to ensure the seal.

 This second method of building swimming pools has certain drawbacks, as regards its cost price which is more expensive than that of swimming pools of the first mode above.

In addition, the right choice of qualified pool engineer and the time of construction are significant parameters that must be taken into account.

 The third method of construction concerns swimming pools with an industrialized structure having walls produced by the assembly of panel elements which, having an identical height and shaped as well in metal, as in plastic, than in reinforced concrete, Resin and wood are prefabricated in the factory in a straight or curved shape. This construction process consists, once the work of the excavator has been done, in peripherally preparing the surface of the basin to receive the

<Desc / Clms Page number 3>

 elements of panels which will be posed and assembled between them. Some of these panels and more particularly those made of concrete are freestanding but most of those used on the market are made of light material imposing a reinforcement of their support which is achieved either by a reinforcement operation and by pouring concrete inside the hollow panels for this purpose, either by adding struts cast in the mass of concrete and often stowed in the ground outside the basin. In addition to stiffening the structure, the presence of these struts has the advantage of supporting the beach which will be laid later. Once the panel elements have been fitted and all the accessories (piping, lighting, discharge pipes, surface vacuum cleaners 1 etc ...) necessary for the operation of the pool installed, the raft can be poured at the same time as a peripheral chaining at the outer base of the basin. Then, after having inserted a felt, the "liner" is installed by snapping on a bead of the "liner" in a hollow profile associated with the upper part of the panels. Then just backfill with the excavated earth and possibly form a high peripheral concrete belt to receive the copings and the beach and finally fill the pool with water so that the pool is ready to dive. This last mode of construction of industrialized swimming pools from elements of prefabricated panels is the most widespread currently occupying more than 60% of the market all the more since these swimming pools are also marketable in the form of structural elements ready to assemble for non-professionals with some notions of earthmoving, masonry, electricity and plumbing. In general, each manufacturer offers its formula with its advantages, which explains why new innovations appearing on the market every year praising the technical-economic performance of the newly-developed technique.

<Desc / Clms Page number 4>

 proposed. Unfortunately, the new techniques proposed by the manufacturers to implement this process of construction of swimming pools with industrialized structure always rest on the same concept namely of the panels prefabricated in factory in a specific material (wood, plastic, metal, concrete, resin, polyester, etc ...) and associated with original means of assembly and stiffening of the structure, generally dependent on the material chosen by them. It follows that manufacturers always offer construction techniques adapted to the panels and to the means of assembly and stiffening that they offer.

 Thus, for example, the formwork, panels or struts proposed in French patent n02573802, in French patent n02758845, or even in French patent n02682980 are specifically dedicated to a particular mode of installation and assembly of panels.

DESCRIPTION OF THE INVENTION
On the basis of this state of affairs and of a predetermined specification, the plaintiff conducted research which resulted in an original concept of construction of swimming pools with industrialized structure which, while applying the principle of the third construction method above , overcomes the aforementioned drawbacks of conventional construction techniques.

 This original concept which is conventionally based on the process of constructing swimming pools with an industrialized structure of the type consisting of a concrete slab surmounted by a peripheral wall defining a basin which, using a plastic film forming a pocket , ensures the tight retention of water in the basin, said peripheral wall being produced from the assembly of panels held at their base in a U-shaped guide rail formed in the raft, is remarkable in that it consists of associate said panels to a frame

<Desc / Clms Page number 5>

 temporary to consolidate the maintenance of said panels on the inside of the basin during the pouring and drying operation of the poured concrete on the outside of said basin between said panels and the walls of the excavation and to release said provisional reinforcement of said panels, a once the casting and drying operation is finished.

 This construction method has the great advantage of reducing the problems linked to the conditions of supply and / or transport of the panels, but also of reducing the costs linked to the specific panels for the construction of swimming pools, since it makes it possible to use, for the implementation of a swimming pool of the traditional type, conventional commercial panels available from any merchant of building materials, even if these have a relative resistance to bending since they will be supported, during the pouring of the concrete, by the provisional reinforcement and then once this last disassembled, by the water of the basin.

The Applicant recommends the use of polyurethane insulating panels used for the insulation of houses.

d'étanchéïté. According to a particularly advantageous characteristic, the construction method of the invention consists in using rectangular panels having at least one surface condition free of defects to receive on the interior side of the basin, the plastic film of the said sealing pocket intended for contain the pond water. Thus, in addition to ensuring the formwork function of the poured concrete, the panels of the invention can also provide the finishing coating capable of receiving the plastic film of the above-mentioned pocket.

of sealing.

 The invention also relates to the provisional frame making it possible to implement such a method of constructing swimming pools. For this purpose, such a frame

<Desc / Clms Page number 6>

 consists of a set of posts which, intended to be regularly distributed around the basin on the inside of said peripheral wall against the internal face of the panels which they must retain, are fitted at their base with a wedging device in the U of the aforesaid guide rail of the panels forming a fulcrum and at their head of a retaining device making it possible to immobilize said posts in a vertical station while keeping said panels constantly applied against the posts during the casting and drying operation concrete spilled on the outside of the panels.

 This provisional reinforcement which, as will be seen a little later in the description supported by the drawings, is of an easy design to implement since it results from the assembly of simple metallic elements, has the great advantage of '' ensure, on the interior side of the pool, the temporary maintenance of conventional commercial panels such as polyurethane insulation panels. In addition, by virtue of its ability to be assembled and dismantled at will, this provisional frame is reusable, which was not the case with the struts of the prior techniques.

Thus, the fish farmer will be able to use the same temporary reinforcement to build several swimming pools and to obtain panels from the merchants of building materials located near the places of construction.

The fundamental concepts of the invention having just been exposed above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving by way of 'nonlimiting example, an embodiment of a swimming pool according to the invention; BRIEF DESCRIPTION OF THE DRAWINGS
