EP1035273A1 - Shuttering assembly, especially for the construction of pools - Google Patents

Abstract

A shuttering system for casting the concrete sides of a swimming pool consists of parallelepiped or cubic extruded modules plastic modules made in two halves (2). The module halves are joined together by male and female couplings (3, 4) on their facing surfaces which form a permanent connection when fitted together. The modules have other couplings (5) along their sides and on their top or bottom edges for attaching to other modules, and their upper edges are shaped to receive pouring grids or pipes. Auxiliary components are shaped to form the corners of the pool.

Description

The invention relates to the field of masonry.

The invention particularly finds its application for the construction and construction of swimming pools. It will be understood, however, that the invention may also be used for the production other types of constructions.

The construction of swimming pools implies the need to pour concrete blocks intended in particular to constitute the walls thereof. This operation, known as banking, is conventionally carried out using conventional wooden formwork. These wooden structures must be removed after construction.

Another formwork technique also conventionally used in the field of swimming pool construction consists in using polystyrene bank blocks that remain in construction after the concrete has been poured inside and solidified there.

These banking blocks however involve many disadvantages.

First, it should be noted that they present usually a standard shape not allowing others to flow elements as the pool walls themselves. So the support device to accommodate the coping should it be made using wooden formwork.

Second, it should be noted that this type of bank block is not not suitable for the production of swimming pools of the overflow trough type.

It should also be noted that such blocks can burst under the effect of the pressure exerted by the concrete.

Furthermore, these blocks have a shape allowing only their edge-to-edge positioning, without lateral guidance, which does not secure their usage.

Finally, it should also be emphasized that such blocks in polystyrene can be parasitized by different animals of small sizes, such as mainly insects, which are often discovered during change of the "liner" (lining element inside swimming pools).

The general objective of the present invention is to provide layering means which do not have the drawbacks of the layering described above.

In particular, an objective of the present invention is to describe a set of layering which allows not only the realization of the walls of a swimming pool but also the realization of the coping support overhanging them and this, whether this support is designed or not to integrate an overflow chute.

Yet another object of the present invention is to disclose such an assembly which presents a quality superior to that of the means existing in the state of the art and which, in particular, eliminates the risks of bursting of the bank blocks.

Also an objective of the present invention is to allow the construction of swimming pools in less time and at lower cost.

These various objectives are achieved thanks to the invention which relates to a laying assembly, in particular for the construction of swimming pools, characterized in that it comprises a plurality of modules for plastic formwork essentially shaped parallelepiped or cubic open in their lower parts and upper, said modules each being constituted by the association of two half-modules presenting male cooperation means and female cooperation means, said male cooperation means and females of each half-module being designed to be combined so irreversible with the female and male means of cooperation of another half module.

The stall assembly according to the present invention therefore has the advantage of including modules each made by assembling two half-modules which fit together definitively and which can withstand significant internal pressures exerted by concrete that we sink there. Such modules are simple and quick to use. The half modules can be produced by injecting plastic and thus have a low manufacturing cost.

Preferably, said half-modules have means side couplings. Such lateral coupling means can be done in different ways. They make it possible to secure the lateral positioning of the bank modules with respect to the others, which turns out to be of great interest for the construction of the walls and for the flatness of these.

Also preferably, said half-modules have longitudinal reinforcements. Such reinforcements can be distributed so uniform on said half-modules. Cut-outs of the blocks may be performed between these reinforcements.

Advantageously, said half-modules have means upper and / or lower coupling. Such means will allow secure the positioning of the modules above one another of others and thus facilitate the pouring of relatively high walls.

Also advantageously, said assembly comprises a plurality of chutes designed to cooperate with the upper part of minus some of said modules and intended to accommodate a formwork for chaining. In addition to the bank modules described above used for concrete wall formwork, the present invention can therefore also include elements allowing the realization of elements other than walls and in particular a coping support arranged on the periphery of a swimming pool.

According to an advantageous variant, said chutes have means for adapting at least one flow grid.

Also advantageously, at least some of said chutes have means for connecting to a pipe. The invention can therefore be used to make pools with an overflow trough.

Preferably, said assembly also includes end caps closure intended to obstruct banked modules arranged at an angle.

Also preferably, said assembly comprises corner angles. Such angles may have a shape reducing angles, thus facilitating the positioning of a liner.

Advantageously, said assembly is made of extruded PVC. We may however use another hard plastic material.

Also advantageously, the bancher set also includes a plurality of fixing pads used to connect two by two the bank modules in their lower part, as well as a plurality of fixing clips to connect the bank modules in pairs in their upper part.

The invention, as well as the various advantages which it presents, will be more easily understood thanks to the description which follows of a nonlimiting embodiment of the latter, given with reference to the drawings in which:

• Figure 14 shows an upper link clip of two adjoining bank modules.

With reference to FIG. 1, a half-module 2 for the realization of Banker modules is shown in perspective.

This half-module 2 is made of PVC and has a length 1200 mm for a height of 500 mm. The internal face of this half-module is provided with male cooperation means 3 and means for female cooperation 4 staggered. These means of cooperation males 3 and females 4 are intended to cooperate irreversibly with the female 4 and male 3 cooperation means of another half-module 2. Such an association of two half-modules 2 constitutes a planking with a thickness of 100mm. It will be understood that in other embodiments, the half-modules may have elements of cooperation male or female of different forms as well as lateral and upper / lower coupling means other than those indicated with reference to this embodiment.

Each half of the bank module is also equipped with lateral coupling means 5 allowing two modules to adjacent layering to be mated to each other. Furthermore, these half-modules are also provided with lower coupling means or upper 8 (depending on the module positioning direction) which allow to couple the bank modules one above the other.

Finally, it will also be noted that the half-modules are provided with longitudinal reinforcement lines 7. As will be seen below, the layering modules made from these half-modules can undergo cuts during their use. Such longitudinal reinforcements 7 allow not to weaken the structure of such modules despite such cuts.

A bank module is shown in section in Figure 2 after assembly of two half-modules as shown in Figure 1.

The irreversible cooperation of male cooperation means with the female means of cooperation and vice versa prevents any separation of the two half modules constituting such a module banking.

The half-modules 2 can be irreversibly combined with together to form modules 1. These modules define between them a volume inside which can be poured liquid concrete. Thanks to the upper coupling means 8, several modules 1 can be stacked on top of each other to create high walls variables.

Another element of the stall assembly according to the invention is shown in Figure 3 and consisting of a corner angle 13. Such corner angles can be installed on wall modules arranged perpendicular to each other and fixed to them on the side of inside the pool. Such corner angles can be made by the association of two flat parts 13a and 13b in PVC and an element 13c angle breaking the angle formed between parts 13a and 13b, and facilitate thus the installation of a liner.

Yet another element of the decking assembly according to the present invention and shown in Figure 4. This element consists of a closing end piece intended to close the lateral faces of a module layering arranged at the end of walls so as to prevent concrete poured inside this module does not spread outside.

With reference to FIG. 5, yet another element of the assembly bank according to the present invention is shown. This element is consisting of a chute 9 designed to be installed in the part upper of a bank module. This chute 9 has adaptation means 10 of a flow grid (not shown), thus as connection means 11 to a pipe.

As already specified above, the banker blocks can be easily cut with a saw to make the pool walls. There are shown with reference to Figures 6 to 11 different states of modules 1 for the production of a swimming pool wall.

More specifically, Figure 6 shows a module for creation of an upper left corner of a swimming pool wall.

Figure 7 shows an upper right corner of such a wall.

FIG. 8 represents an upper interior module of such a wall.

Figure 9 shows an interior module thereof.

Figure 10 shows a lower left corner and Figure 11 a lower right corner.

Referring to Figure 12, there are shown two walls of a swimming pool in progress thanks to the invention using two stages of modules 1, the modules of a stage being offset laterally about 10 cm from the modules on the other floor so that promote overall stability. These modules are represented in transparency so as to show the chains arranged in them to reinforce the concrete which will be poured there. The arrow A indicates an angle in which must be positioned the end cap 12 (as shown in the figure 4). Corner angles can then be added on the face interior. Once all the walls of the pool have been completed, the chutes can be added so as to sink the coping support.

Advantageously, fixing pads, such as that shown in Figure 13, to connect the modules of two by two contiguous banking in their lower part. This skate present in this purpose of the fixing pins.

We will also advantageously use clips as shown in Figure 14 to connect the bank modules in pairs contiguous in their upper part These clips present for this purpose a inverted U section.

The embodiment described here is not intended to reduce the scope of it. As a result, there may be many modifications without departing from the framework thereof.
