Said vertical column is fillable with concrete and, after the hardening thereof, forms a vertical supporting pillar.

Description

The present invention relates to injected plastic panels,

  adapted to be secured with identical or similar panels to constitute the vertical peripheral belt of a swimming pool; it also relates to the pool pool made by assembling such panels.

  A well-known way to make pool pools is to assemble panels of injected plastic material designed for this purpose. Such panels and basins are described for example in the documents FR-A-2 856 332, FR-A-2 850 416 and FR-A-2 818 998.

  The construction of the pool pools corresponding to, initially, to assemble between them the various panels to form a vertical peripheral belt.

  Then, the panels are held in position by means of vertical concrete pillars, regularly positioned on the embankment, so as to withstand the pressure of the water to which they will be subjected following the filling of the basin.

  In most cases, these pillars are made by pouring concrete into a hollow vertical column formwork constituted by an attached structure, also injected plastic material.

  These panel structures for swimming pools are not completely satisfactory because they require the installation of the wall belt in two stages with, first of all, the positioning of the panels, then the establishment of the support pillars. In addition, they require the presence and management of many independent parts, which increases the cost of the corresponding basins.

  To overcome these drawbacks, the applicants have developed a new type of panel whose structure is relatively simple and allows quick assembly to form the vertical wall belt of a pool. These panels are particularly interesting because their assembly automatically forms the vertical columns in which will be cast the concrete constituting the vertical pillars of maintenance.

  For this, the panel according to the invention, made of injected plastic material, consists of a main wall, of generally square or rectangular shape, the two vertical lateral edges of which are provided, along their length, with complementary structures that are congruent and each to form part of a hollow vertical column; the lateral structure of one of the vertical borders of this panel is adapted to be associated with the lateral structure complementary to the other vertical edge of an identical or similar panel, with which it is secured during the construction of the basin, this to form said vertical hollow column, forming formwork, in which can be poured concrete which will form, after setting, a vertical support pillar.

  According to a particular embodiment, the corresponding panel comprises, at each of its lateral edges, a lateral structure whose horizontal section, generally U-shaped, is composed of a bottom flap bordered by two side flaps. look. These two U-section lateral structures are open in two opposite or substantially opposed directions, one in the direction of the face of the main wall intended to come on the embankment side, and the other in the direction of the face of said wall. main intended to come pool side, so as to be each associated with the side structure of the opposite border of an identical panel or the like during the construction of the basin, to form the desired hollow vertical column. Preferably, the distance between the side flaps of the two U-shaped structures is substantially identical and adapted to allow partial interlocking of the two complementary structures during the assembly of two panels.

  According to a preferred embodiment, a first lateral structure is arranged so that its bottom flap is constituted by a portion of the main wall, the two side flaps of said first structure extending from the face of said wall main to be positioned on the embankment side; the second lateral structure is arranged so that its bottom flap extends away from said main wall, and the side of the latter side intended to come embankment side, said bottom flap being connected to the side edge next to of said main wall by one of its side shutters.

  According to another feature, the lateral structures of the panel are provided with orifices capable of receiving horizontal longitudinal locking and stiffening rods, passing through the hollow vertical columns formed by the assembly of the panels, before pouring the concrete.

  In this context, the lateral structures are provided, along their length, and where appropriate in at least some of their side shutters for the U-section lateral structures, with several orifices whose caliber corresponds, with the clearance, to the diameter said stiffening rods, which orifices are formed in said lateral structures so as to come opposite those of a lateral structure complementary to an identical panel or similar reported. Preferably, the passage holes of the stiffening rods are closer together in the lower part of the panels, relative to the upper part, to increase the density of said rods at the bottom.

  According to yet another feature, the main wall of the panel is provided at its upper edge, a one-piece member shaped chute portion whose vertical cross section is generally U-shaped open upwards; this member is intended to form a peripheral upper chute for receiving concrete in view, after setting, to form a peripheral upper retaining edge for the pool.

  In an advantageous embodiment, the panel comprises, at its vertical lateral edges, fastening means tongues / orifices, nestable, complementary to each other. As such, one of the side edges of the panel advantageously comprises a plurality of projecting tabs distributed over its length, and the other vertical edge comprises a plurality of complementary interlocking orifices.

  According to yet another feature, the panel comprises horizontal and / or vertical monobloc stiffening ribs formed at least on its main wall, embankment side; in addition, its lateral structures comprise orifices for the passage of the locking rods, which orifices are arranged in tangency of the vertical plane corresponding to the end of said stiffening ribs.

  The invention also relates to the swimming pool consisting of the assembly of a plurality of molded panels as defined above, associated with reported structures to form the inner and possibly outer corners, the various panels used being associated with rods of horizontal stiffening inserted in their receiving holes.

  The invention will be further illustrated, without being limited in any way by the following description of a particular embodiment, given solely by way of example and shown in the accompanying drawings in which: - Figure 1 is a general view, in perspective , a swimming pool basin made mainly by an assembly of injected plastic panels according to the present invention; FIG. 2 is a perspective view of one of the panels according to the present invention, shown slightly below, on the embankment side; FIG. 3 is a perspective view of the panel of FIG. 2, with a view slightly above the pool side; - Figure 4 is a front view of the panel of Figures 2 and 3 embankment side; - Figure 5 is a front view of the same panel, pool side; - Figure 6 is a side view of the panel of Figures 2 to 5; - Figure 7 is a horizontal sectional view of the panel of Figures 2 to 6; - Figures 8 and 9 show, in two steps, the assembly technique of two panels according to the invention; - Figure 10 is an enlarged sectional view showing the detail of the connecting means between two panels; - Figure 11 is a perspective representation of two panels suitably assembled together, associated with stiffening rods and locking; FIG. 12 is an enlarged view of a horizontal section at one of the hollow columns of FIG. 11, showing the association of two panels and the passage of the locking rods; - Figure 13 is a horizontal sectional view showing the attached means for forming the inner corners of the pool basin; - Figure 14 is a horizontal sectional view showing the reported means for constituting the outer corners of the pool.

  The pool pool peripheral belt 1 shown in FIG. 1 mainly consists of an assembly of panels 2 as illustrated in FIGS. 2 to 7. In the context of the embodiment illustrated in FIG. 1, these panels 2 ensure the realization of the rectilinear parts of the basin, and also the semicircular end shape 3; only the outer 4 and inner 5 angles are formed by means of specific adapted structures, respectively marked 6 and 7, detailed below.

  As can be seen in Figures 2 to 7, the panels 2 consist of a main wall of generally rectangular shape 8 defined by a horizontal bottom edge 9, an upper edge 10, and two vertical side edges 11 and 12. D on the other hand, this main wall 8 has a face 13 intended to be oriented inward, that is to say pool side, the opposite face 14 being intended to be located outwards, that is to say say embankment side.

  On the inside, the face 13 of the wall 8 is flat; the outer side, the face 14 is provided with a plurality of vertical and horizontal stiffening ribs 15.

  At its two vertical lateral edges 11 and 12, the wall 8 comprises means, respectively 16 and 17, which allow to assemble the panels 2 between them, and also to form vertical hollow columns intended to serve as formwork for concrete to shape holding pillars.

  On the other hand, at the level of the upper edge 10, the wall 8 is extended by a trough portion-shaped structure 18 adapted to serve as formwork for concrete in order to achieve a peripheral upper edge around the basin 1.

  The main wall 8, the stiffening ribs 15, the means 16, 17 for assembling and forming the hollow columns, as well as the chute structure 18 are made in one piece by molding / injection of plastics material (for example polypropylene) to form the panel 2.

  The vertical edge 11 of the wall 8 comprises a lateral structure 16 with a horizontal U section composed of a bottom flap 20 and two parallel lateral flaps 21 'and 21 ". main wall 8 (it is therefore in the plane of this wall 8) and the two parallel flaps 21 ', 21 "extend perpendicularly to the plane of said wall 8, from the outer face 14, that is to say say embankment side.

  The outer side flap 21 'is here longer than the inner side flap 21 ", this inner flap 21" consists in the occurrence of one of the vertical ribs of the stiffening structure 15. Between the two side flaps 21 'and 21 ", we note the presence of an intermediate flap 21"', parallel to the previous, whose length corresponds to that of the outer flap 21 '.

  As can be seen in Figure 7 in particular, the wall 8 extends beyond the U-shaped structure 16 by a strip of material 24; and this band 24 is extended by a plurality of tongues 25, regularly distributed over its length. Note in particular in FIG. 7 that these tongues 25 are offset with respect to the plane of the wall 8, of the thickness of the latter, on the side of the external face 14.

  On the other side of the wall 8, the vertical edge 12 also has a U-shaped horizontal sectional side structure 17. This U-shaped structure 17 consists of a bottom flap 26 and two side flaps 27 ', 27 The bottom flap 26 extends parallel to the main wall 8 and is offset with respect to the latter from the side of its outer face 14 (that is to say the embankment side). connected to the main wall 8 by its inner side flap 27 "; the two side flaps 27 'and 27 "have substantially the same length and therefore both extend to the level of the plane of the main wall 8.

  In the vicinity of the U-shaped structure 17, the lateral edge 12 of the main wall 8 has small openings or openings 28 arranged in correspondence with the tongues 25 of the opposite rim 11. These orifices 28 are intended to cooperate with the tongues 25 of the adjacent panel to form interlocking means / positioning participating in the assembly of panels 2 between them.

  The lateral structures 16 and 17 of the wall 8 are complementary to each other in the sense that one of them, on a first panel, can be associated with the other structure of a second panel juxtaposed to form together a hollow column. vertical parallelepipedic section (here rectangular). Each of the U-shaped structures 16 and 17 is intended to form a part of the hollow column in question.

  In FIGS. 2, 4 and 7, it can be seen that the horizontal reinforcing ribs 15 of the wall 8 extend on the external faces of the U-shaped structure 17.

  On the other hand, on the side flaps 21 ', 27' and 27 "of the two U-shaped structures 16, 17, and on the intermediate flap 21-, the presence of horizontally aligned orifices 30 is noted. distributed along the length of the corresponding flaps, and their spacing decreases from top to bottom.

  As will be seen below, these orifices 30 are intended for the establishment of horizontal rods passing inside the aforementioned formwork columns, these rods, as such, participating in the holding pillars and also participating in the maintenance. locking and stiffening the panels 2 assembled.

  These orifices 30 are provided tangent to the vertical plane corresponding to the end of the stiffening ribs 15.

  As indicated above, the upper edge 10 of the wall 8 is equipped with a trough portion 18 whose vertical cross section is generally U-shaped open upwards. The upper part 32 of the wall 8 forms the inner lateral side of this chute 18. A one-piece transverse element 33 forms the bottom of the chute 18, extending on the embankment side, and a vertical or substantially vertical wall 34 defines its outer side. In FIGS. 2 and 3 in particular, it is noted that the bottom element 33 and the outer side 34 extend on one of their sides by flaps, respectively 35 and 36, intended to ensure continuity of sealing during assembly of panels 2.

  In the bottom element 33 is noted the presence of an opening 37 located in the extension of the U-shaped structure 16, so as not to close the upper opening of the hollow columns obtained during assembly of the panels.

  The chute portions 18 comprise transverse stiffening ribs 38 which extend over their entire width and over part of their height.

  The assembly of two identical panels 2 'and 2 "is illustrated in two steps in FIGS. 8 and 9.

  This assembly is carried out initially by engaging the tabs 25 of the first panel 2 'in the complementary orifices 28 of the second panel 2 ", with a slightly oblique presentation, it is then sufficient to align the two panels 2' and 2" , by a slight pivoting, so that their U-shaped structures are interlocked into one another to form the hollow column 40.

  In fact, and as can be seen in the detail view of FIG. 10, the bottom flap 26 and the side flaps 27 ', 27 "of the U-shaped structure 17 constitute three of the sides of the hollow column 40, and the bottom flap 20 of the U-shaped structure 16 of the other panel (which corresponds to a part of the wall 8) constitutes the fourth complementary side of this column 40.

  The side flaps 21 'and 21 "of the structure 16 serve here simply as positioning members, they play virtually no part in the constitution of the hollow column 40 (but this could be different in alternative embodiments).

  In FIG. 10, the slight recess 42, made in the wall 8 at the level of the connection zone with the U-shaped structure 17, corresponding to the doubling zone of two panels 2 ', 2 "juxtaposed, allowing for ensure perfect continuity and flatness of the internal vertical face of the pool.

  In this figure 10, we also note the bayonet end 43 of the outer side flap 27 'of the structure 17, allowing the positioning of said side flap 27' in the alignment of the associated side flap 21 ". between the side flaps 21 'and 21 "of the U-shaped structures 16 substantially corresponds to the spacing between the side flaps 27' and 27" of the U-shaped structures 17, the corresponding spacings being adapted to ensure the fitting of said structures 16 and 17 when assembling the panels 2, as illustrated in FIG.

  In the illustrated embodiment, some horizontal stiffening ribs 15 extend to the intermediate flap 21 located in the bulk of the hollow column 40; of course, appropriate cutouts are provided at the end of the side flap 27 ', or in the horizontal stiffening ribs 15, to allow the end of this flap 27' to come close to the wall 8.

  In an alternative embodiment, the stiffening ribs may be removed on the space of the U-shaped structure 17 of the adjacent panel.

  The following step of the assembly is illustrated in FIGS. 11 and 12, and consists, as mentioned above, in inserting stiffening rods 45 through the orifices 30 formed in the wings 21 ', 21-, 27' and 27 "Lateral structures 16 and 17.

  The stems 45 in question advantageously have several meters in length (for example between 3 and 6 meters); they are made of metal (steel), or preferably of plastic or polyester filled with fibers (for example glass fibers).

  These rods 45 extend horizontally to the back of the walls 8 (embankment side) and within the hollow columns 40. Their implementation constitutes a kind of key ensuring the locking of the panels 2 relative to each other due to the fact that nesting of the side flaps 21 ', 21 "', 27 'and 27" of the U-shaped structures 16 and 17 (it will be noted in this respect that to fulfill this locking function, only two flaps in correspondence may suffice).

  It will be noted here that the particular positioning of the orifices 30 (in tangency of the plane corresponding to the end of the ribbing 15 of the panels) ensures the support of the rods 45 against said ribbing 15 (see FIG. 12), which improves the resistance of said panels. at the pressure of the water contained in the basin.

  In addition, these rods 45 also contribute to improving the strength of the cast concrete pillars in the hollow columns 40.

  As has been mentioned above and as can be seen in FIG. 11, the density of the locking and stiffening rods 45 is greater in the lower part of the panels, with respect to the upper part, to resist optimally at the higher water pressure at the bottom of the pond.

  Preferably, the junctions of the rods 45 to ensure their continuity take place within the hollow columns 40.

  As indicated above, the inner and outer corners 4 of the pool basin 1 are made by means of inserts 7, 6 which are assembled with two panels 2 arranged in different planes.

  A possible internal corner structure is illustrated in FIG. 13, to connect two panels 2 ', 2 "arranged at the square.

  This internal angle structure is composed of an addition of angle 7 in the form of cylinder portion locked in the basin side angle by means of one-piece tabs 46 each passing through one of the orifices 28 of the panel 2 ". external side, an addition 47 in the form of U-shaped pillar ensures the closure of the corner column formed by the two structures 16 and 17 in correspondence, to form a formwork member for concrete post.

  A possible external angle structure is illustrated in Figure 14, again to connect two panels 2 'and 2 "arranged at the square This outer corner structure is in the form of a ribbed curved panel 6 provided at the level of its lateral vertical edges of interlocking structures, type tongues 25 / openings 28 as detailed above, Here again, a U-shaped post-shaped addition 48 is positioned on the end structure 16 of the panel 2 'for form a complete column to form a concrete post.

  The semicircular structure 3 of the pool basin 1 (FIG. 1) can be made by means of panels 2 identical to those detailed above, or folded at one of their ends (for example on the height of the lateral band 24) are positioned one after the other with a suitable angular offset.

  In both cases, the extensions 35 and 36 of the chute portions 18 provide a seal continuity for the peripheral formwork, to achieve the high peripheral edge of the basin.

  The orifices 30 for the passage of the locking rods 45 will be adapted accordingly; it will be possible to provide different positions of orifices used according to the desired angular offsets.

  Of course, the formation of such nonlinear structures may also be obtained by means of curved panels or dihedral, specially adapted.

  Once the whole of the peripheral belt properly prepared in the manner described above, it remains to stiffen by pouring concrete inside the hollow columns 40 and in the upper chute 18.

  It will be noted that the presence of the intermediate flap 21 inside the columns 40 improves the assembly between the two panels 2 juxtaposed, after setting the concrete.

  In addition, the lower portion of the panels 2 may comprise a one-piece chute extending on the embankment side to form a low concrete belt.

  In addition, this lower chute may include adjustable feet (for example at its four corners) to allow a final level adjustment and more generally positioning.

  It will also be noted that some of the panels 2 constituting the waistband of basin 1 will have cutouts (made after molding) adapted to receive conventional pool components such as skimmer, discharge nozzles, lighting, brushes for. floating curtain attachment, etc ...
