FR2689552A1 - Construction system for swimming pool with liner - uses sectional reinforced base components with sloping edges and walls made from hollow blocks filled with concrete after inserting reinforcing steel rods - Google Patents

Abstract

System uses a prefabricated base (1) of a reinforced synthetic material on a bed of gravel (11) surrounded by reinforced concrete components (12) on which the walls (2) are erected. The base has a sloping outer edge (8) and holes (9) for vertical reinforcing elements (10), and can be made in the form of corner (5) and intermediate (6) modules, assembled by means of stainless steel bolts through edge flanges (7). The outer wall (2) is made from hollow blocks which are fitted with concrete after inserting the vertical reinforcing rods (10), and is topped by trough-section components which receive lengthwise reinforcing elements (13) before being filled with concrete. The trough-section components can be made, for example, for expanded polystyrene, with an inner wall which is lower than the outer one to receive the liner fixing rail. The rail is initially nailed to the inner wall of the trough, but has a rear projecting edge (17) for embedding in the concrete. The hollow wall blocks can be of expanded polystyrene, and curved strips of the same material can be fitted inside the corners, where they are fixed with the air of a silicone adhesive. ADVANTAGE - Pool is faster and more convenient to build, at a very competitive cost.

Description

LINER-TYPE POOL CONSTRUCTION SYSTEM
The present invention relates to a system for building swimming pools of the "liner" type.

 I1 is more particularly intended for the production of small pools for individuals, but can be applied to the construction of pools of all sizes, private or not.

 "Linrr'l type pools consist of a flexible plastic sheet stretched over the walls and bottom of a masonry tank. This cover is generally manufactured in the factory, the tank being produced most often in the traditional way to adapt to the dimensions of the chosen model. First, the bottom is made by pouring a concrete slab, then masonry walls comprising, at the top, a sheet fixing rail, are mounted on the periphery of said This method is long to implement and expensive, and it makes it very difficult to comply with the dimensions imposed by the type of tarpaulin used, which means that, once in place, it imperfectly presses against the walls and bottom of the tank and form unpleasant and unattractive folds.

 The system according to the present invention eliminates all these drawbacks. Indeed, it allows the very rapid realization of a swimming pool of the "liner" type, for a very competitive cost and above all guaranteed a perfect adaptation of the tarpaulin and the tank.

 It consists of a combination of a base made from prefabricated modules of reinforced synthetic material, placed on a simple gravel bed and surrounded by a reinforced concrete belt and, on the other hand, a peripheral wall mounted using hollow blocks of known type made of expanded plastic, into which concrete is poured after placing vertical reinforcements anchored on the periphery of the bottom by means of perforations provided for this purpose, said wall being surmounted by a "U" profile, also made of expanded plastic, on which is fixed a sheet fixing rail.

In the appended drawings, given by way of nonlimiting example of one of the embodiments of the object of the invention:
FIG. 1 is a partial perspective representation of the system according to the invention, showing the various elements assembled,
FIG. 2 shows on another scale the "U" profile constituting the top of the peripheral wall,
FIG. 3 shows a part of the bottom provided with a vertical frame,
and Figure 4 is a horizontal section showing the principle used for finishing the interior angles of the wall.

 The device, FIGS. 1 to 4, consists of a bottom 1 of reinforced synthetic resin, of a peripheral wall 2 surmounted by a profile 3 in "U" shape and corner profiles 4.

 The bottom 1 is prefabricated in the factory in polyester or similar material, which makes it possible to obtain precise dimensions and perfectly conform to those of the tarpaulin "liner" used (not shown). It can be made in one piece for small pools or be formed by corner modules 5 and intermediate modules 6 assembled by means of stainless steel bolts thanks to lips 7 directed downwards and provided for this purpose along contiguous edges. The peripheral edges of the bottom 1 are raised so as to form a chamfer 8 and include perforations 9 intended to receive vertical frames 10 ensuring the connection between the bottom, the peripheral wall 2 and the upper profile 3.

 The bottom 1 is placed on a gravel bed 11 surrounded by a belt 12 of reinforced concrete ensuring the rigorous positioning of the assembly.

 The peripheral wall 2 is preferably formed of hollow blocks of expanded polystyrene into which concrete is poured, after the installation of vertical frames 10. These blocks, covered with a suitable coating and / or a felt after assembly, allow , thanks to their remarkable lightness, to facilitate transport and speed up assembly.

However, the wall can perfectly be made using other elements, such as traditional hollow blocks or not in agglomerated concrete, bricks, poured concrete, steel, aluminum or plastic panels, etc.

 The upper profile 3, in the shape of a "U", is used with the hollow blocks of polystyrene and possibly the concrete blocks. It is mounted above wall 2 and is made of expanded polystyrene. Its bottom is crossed by the vertical reinforcements 10 and a longitudinal reinforcement 13 is placed inside before pouring concrete. The internal wall 14 is lower than the external wall 15 so as to receive the rail 16 for fixing the sheet. This rail, initially nailed to the internal wall 14, has a projection 17 embedded in the concrete and ensuring its final fixing.

The internal vertical angles of the peripheral wall 2 are rounded by means of profiles 3 also made of expanded polystyrene glued with silicone adhesive.
The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
