- FIGS. 12-19 illustrate a number of pool shapes which may be constructed in accordance with the invention
- FIGS. 20 and 21 illustrate alternative methods of finishing the upper surface of the coping sections.
- coping section la is formed as a straight section from reinforced concrete. In cross section it is formed in essentially a "T" shape with face 1 formed essentially at a right angle to upper surface 2.
- the aperture 3 is formed with an outwardly sloping face 4 to permit close frictional engagement with a wall panel (not shown).
- Coping section lb is essentially identical to la except that the rear or outwardly facing portion is formed as a solid section without the recess shown in la.
- a hollow aperture 5 extends lengthwise of coping section lb to support a tensioning cable (not shown). The position of the hollowaperture 5 corresponds with the boundary of the two faces forming the recess in the rear of section la.
- Coping section lc is shaped to permit access to a conventional skimmer box and includes an access aperture 6 and a cut-away portion 7 defining the upper part of a skimmer box opening through a wall member.
- Coping sections Id, le, If and Ig illustrate a "fast” curve, a “slow” curve, a "spa” curve and an inverted “step out” curve, the purpose of which will be described later.
- FIG. 2 illustrates plan and vertical crcss-secticna views of various wall members from which it may be seen that the wall members are available as a standard height cr as fractional heights.
- FIG. 2a illustrates an enlarged view of the upper edge of a wall panel showing an inwardly facing rebate 11 for attachment of a membrane liner retaining member (not shown). Adjacent the upper vertical edges of the wail panel are positioned holes 12 which permit the adjacent edges of wall panels to be temporarily held together with a wire tie.

- FIG. 4 illustrates a tensioning cable retaining bracket 14 comprising an upright leg 15 and a right angled flange 16 extending therefrom. A tensioning cable aperture 17 is provided in leg 15.
- FIG. 5 illustrates a membrane retaining member comprising extruded sections 18 and 19 of plastics material.
- Section 18 is adapted to Be affixed to a wall panel and a portion of membrane folded over upstanding leg 20 is releasably secured thereto by section 19.
- an excavation 21 of slightly larger dimensions than the required pool size is made in the ground.
- the floor of the pool is shaped as a smooth convex depression 22 within the perimeter of the excavation.
- the wall panels 23 are set vertically in the excavation, side by side, and are temporarily held together by wire twitches 24 through preformed holes 12 in the side edge portions of the panels.
- the two panels are supported on concrete blocks 25 and located in a galvanized iron base bracket 13 fitting loosely under the joint.
- One of the wall panels is formed, near to its top, with a rectangular aperture in which is fixed a skimmer extension throat, to enable a skimmer box and return fittings to be installed.
- coping sections of corresponding curvature are set in place.
- the coping sections are arranged to overlap the edge joins of the wall panels and the inwardly tapered groove therein ensures accurate face to face location of the wall panels.
- the upper and outer portions of the wall panels Prior to positioning the coping sections, are coated with adhesive grout.
- the adhesive mixture is used also in vertical joints between coping pieces, and in each joing there is cemented a cable bracket 14 which may be of galvanized sheet steel with a top flange 16 hearing on one coping piece, the lower part of the bracket having a hole 15 located at the junction of the coping piece top and the outside face of the downward projection.
- a cable is passed about the coping pieces and through the apertures of the cable brackets and is tensioned by the use of a turnbuckle or the like.
- Certain coping pieces including any that may be made with a reverse curve, convex when viewed from within the pool, are made with holes 5 through them from end to end to receive the cable, the cable brackets being omitted.
- FIG. 7 illustrates a partially completed pool in which a vacuum pipe is installed which may suitably include an elbow 24 with one end opening into the pool through a hois at or near the bottom of one wall panel, its other end connected to an upright pipe 25 to the outside of the panel, the top of this pipe being connected, through a further elbow 26, to one end of a discharge pipe 27 below the coping and inclining down towards its other end.
- the purpose of the vacuum pipe is to facilitate the positioning of the pool liner membrane and to allov/ for discharge of any water which may find its way between the liner and the pool interior. Water seeping inwardly via hydrostatic valve 28 from surrounding ground is forced up to the perimetral join between the pool wall and floor and is discharged by a siphon action via pipe 27.
- the hydrostatic valve simply comprises a tube 28 extending from a drainage pit 29 beneath the pool floor.
- a concrete bottom 30 is laid for the pool and is trowelled smooth, and concrete is also poured between the wall panels and the excavation.
- a liner retaining section 18 as illustrated in FIG.5 of any suitable material such as plastics is riveted to the upper inside parts of the wall panels, within the rebates thereof, the section consisting of a flat upright section which is riveted adjacent its lower edge flat against the rebated section 11 of wall panels the upper edge being retained in the tapered aperture 3 of the coping section.
- a membrane liner, preferably vinyl, for the pool has its upper edge portion folded over a liner retaining strip 19. which is of inverted-channel form, the excess liner portion hanging down outside the main part of the liner wall.
- the retaining strip 19, with part of the liner wrapped about it, is hooked into engagement with the channel of the liner retaining extrusion, the overhang of the excess liner being adjusted to suit the pool and to ensure that the seam where the wall of the liner joins the liner bottom is correctly located.
- a particular advantage associated with this liner retention means is that not only does it firmly retain the liner edge in position by a self-locking action, but the retention means is readily reieasable to allow adjustment cf tension on the liner material e.g. to take up stretch or to reduce tension.
- a vacuum pump connected to the pipe 27 is used to withdraw air from between the liner and the pool bottom and sides before the pool is filled with water.
- a pool may be made with a step out section as illustrated in FIGS. 8 and 9 by using reduced height wall panels for one section of the lower part of the pool wall, and shallow wall panels, including panels reversed for inverted curves, above the level of this lower wall section, to result in a shallow outward extension of the pool structure, this outward extension being provided with a concrete floor and a coping.
- the vinyl liner has a part cut away at the opening to the step out section, the edge of the opening formed in the liner being secured to the pool wall panels with the auxilliary retaining member 30 illustrated in FIG. 10.
- the function of the auxilliary retaining member is similar to that of the main liner retaining member of FIG.
- a spa may also be formed at the perimeter of the pool as shown in FIG. 11.
- a step out construction is formed as described above but an inner wall 34 is formed to isolate the spa from the pool.
- the vinyl liner is not cut away at this region but continues around the inner wall of the pool.
- a false floor 35 is provided with a plurality cf apertures to permit air to enter the spa from a source of pressurized air 36.
- Inlet and cutlet orifices 37 are provided for circulation of heated water.
- FIGS. 12-19 illustrate some of the many pool shapes which may be constructed with the apparatus and according to the method of the invention. As illustrated, the optional features of step out and/or spa may be readily included in the construction.
- a particularly advantageous feature of the present invention resides in the retaining means for the tensioning cable. Should the cable slip downwards during the tensioning step, the coping sections may become misaligned and thus become difficult if not impossible to realign before the grouting adhesive sets.
- the cable retaining brackets obviate the possibility of such a misalignment
- a further advantageous feature is the provision of the apertured coping sections for use in those regions where inverse curvatures would otherwise precluce a perimetral tensioning cable.
- the cable being held captive within the inversely curved coping section exerts an outwardly directed force under tension on the coping section which counteracts an inwardly directed force as the section undergoes compression from neighbouring coping sections. It can be readily seen therefore that the features of the present invention may be adapted to a wide variety of pool shapes while at the same time retaining structural integrity.
- the coping sections of the present invention are adapted to permit a wide variety of surface finishes.
- FIGS. 20 and 21 illustrate two different types of finishes.
- the inwardly projecting lip 38 may be tiled and a conventional nosing tile 39 is situated adjacent the front upper edge of the coping section.
- An aggregate finish 40 may be applied to the remaining upper surface of the coping section and a rebate 41 in the rear edge permits the aggregate finish to be taken over the rear portion of the coping section. Not only does this feature give the illusion of a thicker aggregrate finish but it prevents chipping of the finish at the rear edge.
- FIG. 21 illustrates a conventional brick finish comprising bricks 42 set in mortar 43.
