15. The mould according to claim 14, wherein the average roughness value Ra of the first texture is from 1.1 to 1.6 m.

16. The mould according to claim 15, wherein the average roughness value Ra of the first texture is 1.2 m.

17. The mould according to claim 8, wherein the first texture which has an average roughness value Ra from 0.8 to 4 m.

18. The mould according to claim 17, wherein the average roughness value Ra of the first texture is from 0.9 to 2.4 m.

19. The mould according to claim 18, wherein the average roughness value Ra of the first texture is from 1.1 to 1.6 m.

20. The mould according to claim 19, wherein the average roughness value Ra of the first texture is 1.2 m.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0039] With the intention of better showing the characteristics of the present disclosure, an application of the method for manufacturing a swimming pool or swimming pond or the like according to the present disclosure with associated mould according to the present disclosure is described hereinafter, by way of an example without any limiting nature, with reference to the accompanying drawings wherein:

[0040] FIG. 1 shows a cross-section of a mould according to the present disclosure, with indication of the first [0041] steps of the method according to the present disclosure;

[0042] FIG. 2 shows the next step of the method according to the present disclosure;

[0043] FIG. 3 shows the next step of the method according to the present disclosure;

[0044] FIG. 4 shows a preformed swimming pool obtained by applying the method as illustrated in FIGS. 1 to 3.

DETAILED DESCRIPTION

[0045] FIG. 1 shows a mould 1 with the convex side facing upward and provided with a texture T m on the convex side.

[0046] A layer of wax 2 as mould release agent is provided on this upwardly facing convex side.

[0047] Schematically, a supply pipe 3 is shown for the supply of plastic in powder form 4, which is heated in and/or on the level of an also schematically shown spray nozzle 5 and applied on the convex side of the mould 1.

[0048] Thus a first plastic layer 6 or first polymer layer 6 is provided, in this case a modified polyolefin, as shown in FIG. 2.

[0049] In a next step, shown in FIG. 3, the first plastic layer 6 or first polymer layer 6 is provided with a first epoxy layer 7A on which a first fibreglass layer 8A is provided. After polymerisation of the first epoxy layer 7A, a second epoxy layer 7B and a second fibreglass layer 8B are applied in this application. Obviously, several of the structural 5 layers may be provided, and for each of the epoxy layers alternatively polyester or vinylester can be applied for example.

[0050] After polymerisation, the thus obtained product 9, in this case the preformed swimming pool 9, is removed from the mould 1 for further finishing and installation on the site.

[0051] It is understood that the preformed swimming pool 9 is installed, for example in an excavated pit, with the concave side facing upward, such that the visible side is the first plastic layer 6 when in use.

[0052] The aspect of the present disclosure is that the first plastic layer 6 which is provided on the mould 1 will be the visible layer of the swimming pool when in use. The first plastic layer 6 shows a substantially corresponding texture T_p on the free surface as the texture T_m provided on the convex side of the mould 1.

[0053] The texture T_p causes minor scratches or repairs to be less visible.

[0054] In this embodiment variant as shown in the figures, the texture T_m is determined such that the texture T_p which is obtained on the visible inside of the swimming pool 9 corresponds with the texture T_r as obtained on the free surface by applying repairs by the local application of a plastic layer supplied in powder form which is heated and applied on the area to be repaired. Such repair will barely be visually noticeable.

[0055] For the sake of clarity: [0056] T_m stands for structure of the mould 1 on the convex side; [0057] T_p stands for the product, in this case the swimming pool 9, on the concave side or inside; [0058] T_r stands for structure as obtained on the free surface when a plastic layer in powder form is heated and applied, such as for example when carrying out a repair to a swimming pool.

[0059] It is understood that the specific choice for the structure T_p is optional.

[0060] The present disclosure is by no means limited to the embodiment of the mould and applied method for manufacturing a swimming pool or swimming pond or the like described by way of example and illustrated with reference to the figures but can also be realised in other ways without departing from the scope of the present disclosure.
