Definitions

  • ABSTRACT OF THE DISCLOSURE Sunken swimming pool comprising lining means which define the water-receiving basin and include side walls having a plurality of substantially horizontally extending steps in superimposed relation to each other substantially throughout the vertical extent of the side walls, the steps having a mean slope which is downwardly inclined inwardly of the pool.
  • the object of the present invention is to remedy this drawback.
  • the invention provides a sunken swimming pool comprising a lining, the side walls of which, instead of being vertical, have a stepped shape, the mean slope of which is inwardly and downwardly inclined, said stepped walls @being backed up by a mass of aggregates o1' powdery material, for example sand.
  • the thrust of the aggregates or powdery material is exerted only on the portion of the vertical face of each step between the foot thereof and the intersection with this face of the plane intersecting the lower edge of the step located immediately above and making with the horizontal an angle equal to the angle of internal friction of the powdery material.
  • the mean value of it is possible, in providing five steps in respect of a total depth of 2 metres, to arrange that the thrust of the earth be exerted on only half the vertical extent of the stepped wall.
  • the latter is normally anchored at its top and bottom ends and calculation shows that, bearing in mind that the thrust is proportional to the square of the height, the resulting forces are very small compared with those in conventional constructions.
  • An excavation is first made which is oversize relative to the volume which the basin of the pool must occupy, the floor is formed, at least the bottom step of at least Y one of the side walls is constructed from the bottom by connecting it to the floor of the pool, the bottom step, and if desired the following steps, are shored from the interior of the basin, the space formed by the oversize between the already constructed steps and the slope of the excavation is filled with a powdery material, the mass of powdery material thus formed is compacted, the other steps of the lateral walls are constructed one after the other by alternating the mounting of the faces of the steps with the filling of the oversize combined with the shoring of the steps from the inside, and finally the vertical face of the top step is anchored, for example 'by means of a reinforced concrete paving.
  • the floor and the walls of the lining are preferably constructed by the assembly of elements of, for example, metal, plastics material, or reinforced plastics material, by a method which, according to the invention, comprises assembling in end-to-end relation or at right angles plates or anges of profiled sections by the use of joint covers and rivets (known under trade name of Rivelon having a ring mounted by a plastic ⁇ deformation when cold), with interposition of a sealing material.
  • perforated vertical partitions in vertical alignment with the vertical face of the bottom step for example, and t0 cover by means of a flooring the space between the vertical face of the top step and the top of the perforated partitions.
  • FIG. 1 is a sectional view of a side wall of a rectangular pool according to t-he invention
  • FIG. 2 is a partial plan view of the pool
  • FIG. 3 is a perspective view of one corner of the pool
  • FIGS. 4-6 are detail views showing the assembly of plates or profiled sections constituting the walls or the floor of the pool lining;
  • FIG. 7 is a view similar to FIG. 1 of a variant of the embodiment of the wall of the lining;
  • FIGS. 8 and 9 are diagrammatic sectional and plan views respectively of a lining of a pool of varying depth
  • FIG. l0 is a diagrammatic perspective view of a portion of a variant of the pool according to the invention.
  • FIGS. ll-15 are views of accessories employed in combination with the pool shown in FIG. 10.
  • rIhe pool according to the invention comprises a rectangular basin or lining embedded in an excavation formed in the natural ground with interposition of a mass of sand 2.
  • This lining is obtained by the assembly of skin-forming elements the thickness of which is as a rule constant, these elements being composed of a moulded material or sheet metal.
  • the material employed is preferably polyester reinforced for example with glass fibres.
  • the bottom or tioor ⁇ 3 of the lining is plane and the side walls 4 and ⁇ 6 have a stepped profile which affords the advantage (see line 7 corresponding to the slope of equilibrium of the sand 2) of exposing only about half the height of the walls to the thrust of this sand.
  • the bottom 3 is constituted by the end-to-end assembly of rectangular plates A the joints a of which constitute a regular square pattern.
  • the walls are constituted mainly by the assembly of profiled sections B which have a crosssectional shape in the form of a zig-zag line defining a complete step S and on each side of the latter two half steps 9 and 11 respectively representing a part of the upper and lower adjacent steps so that by connecting by 3 means of a joint b the upper half step 9 of a section B to the' lower half step 11 of a second section B superimposed on and offset relative to the' lirst section B there is obtained the main part of a lining wall (FIG. 1).
  • the section B When viewed in plan, the section B denes two step tops 12, 13, the longitudinal adjacent ends of which are offset with respect to each other and adapted to be assembled by joints c to the complementary ends of the steps tops formed on another section B disposed in the extension of the aforementioned section. Further, the arrangement of the two superimposed sections B to constitute the transverse section shown in FIG. 1 is such that the bottom step top 13 of the highest section B has its longitudinal ends also offset relative to those of the subjacent section B so that in plane the joints c have a shape inthe form of a'regular zig-zag line. Vertical joints d and horizontal joints e are also provided for connecting the adjoining ends of sections B disposed in end-to-end relation (FIG. 2).
  • the relative offset of the step tops extends upwardly of the water-receiving cavity or basin toward one of the corners of the pool as concerns both the end wall 6, half of which is shown on the left of the drawing, and the side wall 4 (which is the only one shown).
  • a moulded corner element C which forms steps, has a height which corresponds to that of two superimposed sections B and is connected to the adjacent sections B by suitable joints f, g, h, i.
  • a moulded compensating element F has been inserted between these sections B and the corner element C.
  • the assembly of the lining is completed, on one hand, throughout the periphery of the bottom, by angle irons or L-shaped members D which are connected by joints k, l, m respectively to the bottom plates A, to the bottom half steps 11 of adjacent sections B and to the lower part of the corner elements C and, on the other hand, at the top of the walls, by L-section members E which are assembled by joints p, q respectively to the top half steps 9 of the top sections B and to the top part of the corner elements C, these L-section members being anchored or sealed in a reinforced concrete paving 1i6 which rests on the mass of sand 2 interposed between the excavation and the corresponding wall of the lining.
  • FIGS. 4-6 The construction of typical assembly joints for the various elements of the lining is shown in FIGS. 4-6.
  • FIG. 4 shows the assembly of two floor plates A by means of a joint cover 18 and rivets 19 of the aforementioned rivelon ytype inserted in aligned apertures 21 and 22 in the two plates to be assembled and in the joint cover.
  • the heads of the rivets are of the countersunk type and are retained in corresponding countersinkings ofv the apertures 21.
  • the plates are clamped together by the insertion of a ring 23 in the grooves of the rivets.
  • a layer 24 of a sealing material as the product known under the trade name Thioex (rubber having a polysulfide base) is interposed between the plates A and the joint cover 18.
  • the rivets could be immersed before being placed in position in a sealing liquid which can also be of Thioex, and the surface of the plates remote from the joint cover could'also be covered with a strip of butyl rubber 26 secured by means of an adhesive or a paint, as the product known under the trade name of Hypalon.
  • Sealed assemblies of the type just described are normally employed for the construction of the joints such as c, g, h, k (FIGS. 2 and 3).
  • the assembly shown in FIG. differs from that shown in FIG. 4 only in respect of the substitution for the plates A of the flanges of sections B or L-section members D, E. It concerns the construction of the joints b, l, p.
  • top L-section member E is anchored in the concrete paving 16 by means of blocks 31 which are stuck or welded at -l'equired intervals on the outer face of the joint cover 18 pertaining to the horizontal join-t p.
  • the reinforcements 32 of the paving 16 are fixed for example by a screw thread in these blocks 31.
  • a ooring 70 covers the space between the edge of the paving 16 and the top part of a vertical partition 71, perforated at 72, which extends from the bottom half step 1 to the level of the paving 16.
  • The'assernbly of the flooring 70 with the vertical partition 71 and the assembly of the latter with the half step 11 are achieved for example by means of angle irons or L-section members 73 or 74 secured'by rivets or bolts 76 or 77.
  • FIG. l0 is a diagrammatic view of a pool whose peripheral paving lof concrete 40 has a raised part 41 forming a platform or quay which is located above a wave breaker 42. With this arrangement it is possible to equip the pool with the accessories shown in FIGS. l1-l5.
  • FIGS. 1l and 12 show a competition starting block or pedestal which can be removed during the normal bathing period.
  • This block 43 is formed by a hollow case the upper part 44 of which slopes toward the basin and permits a departure for normal swimming.
  • the block is xed to the quay 41 by means of embedded nuts 46 xed in the quay and in which are screwed bolts 47 extending through a ⁇ part 48 of the case which has an L-section and fits against the raised portion formed by the rear of the quay 41 and the top of the paving.
  • Set into the vertical face adjacent the ybasin is a bar 49 which can be gripped by the swimmers for the start of back stroke swimming.
  • a mast 51 is fixed to the quay 41 by a sleeve 52 welded to a base plate 53.
  • the latter bears on the quay and is attached thereto by means of a U-section portion S4 adjacent the basin and bolts 56 screwed in nuts 57 embedded in the vertical part of the quay adjacent the beach.
