AMENDED CLAIMS

received by the International Bureau on 18 November 2016 (18.1 1.2016)

1. A swimming pool, including an upright plastic sidewall, where the plastic sidewall is slidably arranged with respect to an underlying structure of a building structure characterized in that the plastic sidewall is connected to the building structure by a connecting device which allows small displacements of the base of the sidewall in a plane parallel to the underlying structure of the building, the small displacements being a consequence of the thermal expansion or shrinkage of the plastic sidewall, without inducing any significant thermal stress in the sidewall or connecting device.

2. A swimming pool according to claim 1 , where the plastic sidewall is connected to the underlying structure of the building by a sliding clamping connection.

3. A swimming pool according to one of the previous claims, where the. plastic

sidewall forms a closed, whole sidewall of the swimming pool.

4. A swimming pool according to claim 4, where the plastic sidewall is connected to the structure of the building by a connecting device, where this connecting device allows an expansion of the sidewall in a direction parallel with the sidewall, without inducing significant thermal stress in the sidewall.

5. A swimming pool according to claim 5, where the connecting device allows a displacement of the sidewall in a direction perpendicular to the direction of the sidewall, without inducing significant thermal stress in the sidewall.

6. A swimming pool according to claim 5 or 6, where the connecting device contains an L-shaped part situated at the bottom of the sidewall and a part situated in the underlying structure of the building, specially shaped to receive the L-shaped part, thereby establishing a sliding clamping connection.

7. A swimming pool according to claim 5, where the plastic sidewall is connected to the structure of the building by connecting bolts, fitted in slotted holes in the base of the sidewall, and where the slotted holes have a predefined shape and direction to minimize thermal stress in the sidewall when the sidewall

experiences thermal expansion or shrinkage, while being connected by the clamping device.

8. A swimming pool according to one of the previous claims, including a swimming pool floor arranged in such a way that it can glide relative to the structure of the 19

building and it is made of a plastic with the same coefficient of thermal expansion.

9. A swimming pool according to claim 9, where the plastic sidewall is watertight connected to the floor of the swimming pool.

10. A swimming pool according to one of the previous claims, where the sidewall consists of modular plastic modules.

11. A swimming pool according to claim 11 , where the plastic modules are single- walled or double-walled with reinforcement ribs.

12. A swimming pool according to one of the previous claims, where the plastic of the sidewall is chosen independently from the collection of polypropylene, polyethylene, PVC, acrylic or acrylic composites.
