Description

The present invention relates to a construction module for a swimming pool, a swimming pool belonging thereto.

While a home pool was an elusive dream for many homeowners 20 years ago, entrepreneurs have since developed a whole range of inexpensive prefabricated or inflatable pools, made of resin or wood.

However, these pools are often entry-level models that often deteriorate quickly or develop leaks, requiring the regular visit of professionals to repair.

Thus, poured concrete swimming pools remain the preferred solution to ensure the long-term operation of a swimming pool.

In addition, a concrete swimming pool is often the only feasible technical solution on slopes.

However, the production of such a swimming pool from concrete is lengthy and requires very heavy work, in particular excavation and formwork. In addition, after each concrete pouring step, the concrete must be cured before site work can proceed, which increases the cost of such a pool.

In addition, the climatic conditions are not always present so that the setting and curing times can be adhered to.

The document FR2903442 describes a swimming pool made from prefabricated modules made from resin panels. The modules are mechanically attached to each other and the seal is achieved by applying an adhesive seam.

This swimming pool construction has several disadvantages. In particular, a bottom plate for the swimming pool (swimming pool floor) needs to be prepared in advance, and it is not easy to make the seal tight when attaching the modules to the plate.

The document US2014017820 also describes a swimming pool made from prefabricated modules. Gaskets are provided between the modules, which are bolted together. The modules are made of resin or fiberglass but not concrete and the pool has the same disadvantages as those of the previous document.

Finally it's over FR2812677 a swimming pool made of concrete modules.

According to the manufacturing process described in this document, a pit is made whose dimensions are significantly larger than the dimensions of the swimming pool to be made. Then, vertically and side by side, but without being connected, prefabricated concrete modular wall elements are arranged to be assembled. Finally, a concrete pad is poured onto the bottom of the pool.

It can therefore be seen that the erection of these concrete modules remains lengthy and laborious.

The aim of the present invention is to at least partially eliminate certain of the disadvantages described above.

To this end, the invention relates to a construction module of a swimming pool, characterized in that it includes a reinforced concrete wall with metal reinforcing bars located in a lower portion of the construction module intended to be close to the ground of the swimming pool, the metal reinforcing bars comprising free ends projecting with respect to an external surface of the module.

The metal reinforcing rods, which protrude with respect to an outer surface of the construction module, allow an improved hold of the same during installation and ensure reliable stability of the module over time. This solution is particularly suitable in the case where the construction modules are only partially embedded in the pit that will house the pool.

Other advantages and characteristics of the invention will appear on reading the description of the invention and the attached drawings, in which:

• [ 2 ] is a schematic perspective and sectional view of a construction module; and
• [ 3 ] a side sectional view of the construction module from [ 2 ] is.

The following statements are examples. Even if the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment or that the characteristics apply only to a single embodiment. Simple features of different embodiments can also be combined to provide further embodiments.

[ 1 ] shows, by way of example and according to a schematic perspective view, two construction modules 1 and 3 of a swimming pool during assembly. These two modules 1 and 3 are particularly intended to be assembled at 90°, that is to say at a right angle.

With reference to the different figures, each construction module 1 or 3 of a swimming pool includes a wall 5 of reinforced concrete.

The reinforced concrete of wall 5 is provided with a water-repellent sealing additive. The module 1, 3 is therefore watertight, so that no additional internal sealing of the swimming pool is required, such as with foil or tiles.

In addition, the concrete may contain crack-resistant fibers. These fibers are, for example, synthetic fibers, which are particularly assume a lattice function as the concrete shrinks after pouring.

As in the 1 until 3 , showing external surfaces 4a of the walls of the modules 1, 3, such construction modules 1, 3 incorporate, in a lower portion 6 intended to be located near the bottom of the swimming pool, metal reinforcing bars 2, comprising free ends 2a projecting with respect to the outer surface 4a. The metal reinforcing bars 2 are made of steel, for example, but other metal materials are also conceivable for this type of construction. The free ends 2a of the metal reinforcing rods 2 protruding from the outer surface 4a of the construction module 1, 3 ensure stability during and after the construction of the pool, especially in the case where these construction modules 1, 3 of the pool are only partially in are embedded in the earth. For example, the swimming pool can be built on uneven terrain.

More generally, the lower portion 6 of a wall 5 of a construction module 1, 3 may have a "T" shaped foundation to further enhance the stability of the module.

In general, the wall 5 has a cuboid shape, which has a height H, a width L and a thickness E. The wall 5 has, for example, a thickness E of between 10 cm and 30 cm, in particular 18 cm, which is sufficient to obtain a module 1, 3 having good watertightness without being too heavy. It goes without saying that the width L and the height H of the wall 5 are chosen as a function of the dimensions of the swimming pool to be installed.

According to the embodiment of the construction module 1, 3 shown in [ 3 ], the length of the free end 2a protruding with respect to the outer surface 4a of the structural module 1, 3 is at least 1.5 times the thickness E of the module 1, 3. The length of this free end 2a can be e.g be twice or even three times the thickness E of the module 1,3.

In particular, with reference to the sectional view of the module illustrated in this same figure, the metal reinforcing bars 2 comprise a bent portion C forming a right angle. This curved portion C is located inside the concrete wall 5 so that only the free ends 2a of the metal reinforcing bars 2 are visible.

The metal reinforcing bars 2 thus bent each comprise a short branch 2b and a long branch 2c, these branches 2b and 2c being located in particular on either side of the bent portion C so as to give the metal reinforcing bar 2 a general L-shape. The length of the short leg 2b is, for example, greater than or equal to one third of the length of the long leg 2c, which is inside the construction module 1, 3.

According to the in the 2 and 3 In the illustrated embodiment, the short leg 2b extends laterally and preferably horizontally with respect to the outer surface 4a of the structural module 1,3, while the long leg 2c extends vertically inwardly of the structural module 1,3. In order to ensure the stability of the construction module 1, 3, the long leg 2c of such a metal reinforcing bar 2 extends over a distance D which is at least 30% of the height H of the module 1, 3 and in particular 60% of the height H of the module 1 , 3 corresponds.

According to an unillustrated embodiment of the construction module 1,3, the metal reinforcing bars 2 can be parts attached to the construction modules 1,3. In this case, the metal reinforcing bars 2 can be fixed to the wall 5, for example by screwing or any other fixing technique, so that they protrude with respect to the external surface 4a of the module 1,3.

The wall 5 of a construction module 1, 3 can include, on its inner surface 4b side, i.e. the surface intended to be in contact with water once the swimming pool is assembled, a pre-assembled integrated reinforcement intended to to be connected to a sole.

This integrated reinforcement in the lower part 6 of the wall 5 of the module 1, 3 includes, for example, a storage box with rebend connections, which is used in particular in the 2 and 3 you can see. According to the embodiment illustrated in these figures, the bent portion C of the metal reinforcing bars 2 is at the same level as the storage box with rebend terminals.

Once the modules 1, 3 are installed, the irons in the containment boxes can be deployed, sole reinforcement fabricated and their irons connected to those now protruding from the containment boxes, before pouring the sole concrete with the required quality concrete.

According to another aspect of the invention, the modules 1 and 3 are assembled mechanically fastened together, eliminating the need for special formwork and pouring concrete to connect two modules.

In addition, a water-swelling seal 27 can be provided within the wall of the module 1,3. Part of this water-swelling seal 27 can in particular reach up to the inner face 4b of the module 1, 3 in the region of its lower portion 6 intended to be in contact with the bottom of the swimming pool. This part of the water-swelling seal 27 thus extends horizontally over at least part of the length of the wall 5 of the construction module 1, 3. Another part of the water-swelling seal 27 can also extend according to a vertical direction over at least 85% of the height H of the module 1, 3 and in particular over the entire height H of the module 1, 3 extend. This part of the water-swelling seal 27 thus extends parallel to the long leg 2c of the metal reinforcing bar 2 located inside the wall 5 of the structural module 1,3.

The water-swelling seal 27 is, for example, one centimeter thick and is intended to cooperate with a groove of a similar size to ensure the tightness of the connection between two adjacent structural modules 1, 3.

In addition, the construction module 1, 3 can integrate additional accessories, in particular lighting devices, portholes and water treatment nozzles, so that once the modules 1, 3 have been installed, the swimming pool is ready for use.

The modules 1, 3 are prefabricated in the factory from reinforced concrete with the dimensions desired by a customer and are equipped, for example, with nozzles, lighting devices or portholes. The swimming pool according to the invention consists, for example, of several structural modules 1, 3 arranged in a straight line next to one another or at right angles to one another, as is particularly the case in [ 1 ] is illustrated.

Such a swimming pool according to the invention can also be installed half-sunk into a slope, with lighting devices in the form of LEDs on the side that is buried in the ground and with viewing portholes on the side that is not buried in the ground, in order to have a view of, for example, a valley offer, but also above ground or completely submerged in the ground.

The construction of such a swimming pool is quick and easy. After the earthworks, at each connection between two construction modules 1, 3, in particular at the four corners of the pool ([ 1 ]), foundation plates 25 cast. These foundation plates 25 allow in particular the leveling of the modules 1, 3.

Then, using a lifting device such as a crane, each module 1, 3 is lifted in order to place it in the desired location, taking care to ensure that the free ends 2a of the metal reinforcing bars 2, which are in relation to the external faces 4a protruding, pointing sideways to the outside of the pool.

Before final placement and attachment, one of the modules (see [ 1 ]), the seal 27, for example a water-swelling seal, attached.

Then the modules 1 and 3 are assembled and fastened to one another by screwing, which means that inserts 15 are screwed into sockets provided for this purpose and then the modules 1, 3 are screwed together. The inserts 15 are located in particular at the ends according to the height H of the construction modules 1, 3. They are located, for example, about ten centimeters from the upper and lower edges of the construction module 1, 3 under consideration. In this way, the tightness can be maximized.

According to the following step, a sole reinforcement (grid not shown) is introduced on the inside 4b of the modules 1, 3 and this is connected to the reinforcements that are integrated into the construction modules 1, 3.

Then the sole is poured with a concrete containing a water-repellent sealing additive, both inside the sole reinforcement inside the space formed by the construction modules 1, 3, and on the outside of this space, around the free ends 2a of the reinforcing bars of metal 2 protruding with respect to the outer faces 4a of the construction modules 1,3.

It can thus be seen that the free ends 2a of the metal reinforcing rods 2, which protrude with respect to the external faces 4a of the structural modules 1, 3, make it possible to reinforce the support of the modules during this step.

Once the sole has hardened, another seal can be applied to the inside edges of the pool for an aesthetic finish.

The surface finish of the construction modules 1, 3 can be very smooth thanks to the manufacture in the factory, which is not subject to climatic fluctuations and can take curing times into account.
