Definitions
- the present invention relates to a half-module for the formation of lost formwork elements for the construction of swimming pools, in particular having walls whose height varies gradually, a lost formwork element, and a method of building swimming pools.
- Public pools are generally shallow at one end. Users can stand on the bottom, and thus get a sense of security. At the opposite end, the pool has a great depth, sufficient to allow for example diving. Between these extremes, the depth varies gradually.
- Private pools have limited dimensions. Their pelvis usually has a constant depth. Sometimes the bottom of the basin forms two or more parts of different depths that are separated by a kind of step. Other pools include, inside the walls and away from them, a dive pit dug to one end of the pool.
- the invention relates to the construction of swimming pools, including inclined bottom, using lost formwork elements, formed of half-modules.
- WO 2006/035123 discloses lost formwork elements in which two panels injected with localized spacers are mounted on either side of a frame to form shuttering modules. These modules are used for the construction of pool walls by connection of the shuttering elements by separate connecting members. When the panels are small, they can be made with inexpensive injection presses. However, because of the presence of the spacers, the panels occupy a large volume during transport.
- the document FR-2,790,777 describes lost formwork modules formed by back-to-back support of two half-modules by means of cooperation. Lateral coupling means and upper and / or lower coupling means may also be incorporated in the half-modules. Each module is used in the manner of a building block (brick, block) since the module is cut differently according to its location in the construction, and superimposed modules are shifted laterally.
- Document FR-2 842 555 describes an improvement of the aforementioned system in which each half-module has at its edges an internal rib, and adjacent modules can be connected by "coupling means" which are separate members of the half-modules. modules and which are intended to overlap the ribs of two adjacent half-modules.
- the half-modules described have a large dimension, and have the disadvantage of occupying an important space during their transport from the manufacturing workshop to the construction site of the pool. Less bulky panels have already been made during transport.
- the document FR-2 778 933 describes panels made by back-to-back association of two half-panels.
- the panels obtained can be associated side by side for the construction of long walls.
- the half-panels When the half-panels are not associated, they can fit into each other, so that they occupy a small volume.
- These panels which have a height of 1, 1 m approximately, can be coupled side by side but not from bottom to top.
- These panels are very convenient, but they require for their manufacture of injection molding machines of great power (several thousand tons) and thus expensive molds. As a result, each manufacturer limits its manufacture to a small number of panel heights, usually one or two.
- the pool walls made with lost forms are made of reinforced concrete; thus, before pouring the concrete, reinforcing bars are placed inside the panels and, preferably, are folded at their lower part towards the interior of the pool to be embedded in the poured concrete to form the raft from the bottom of the pool. It is known that it is advantageous to communicate the bottom of the space of the lost formwork with the raft so that the reinforced concrete of the walls is anchored on that of the base of the bottom of the pool.
- a relatively thick pool wall, having cells is preferable to a thinner wall without cavities.
- FR-2 778 933 describes such a lost formwork system in which spacers delimit cells intended to contain no concrete.
- the invention relates to a system for manufacturing lost forms for swimming pools for the construction of swimming pools having an inclined bottom.
- the construction must be carried out according to the technique of side-by-side layout of formwork elements whose interior communicates for the passage of concrete, because it significantly reduces the time and difficulty of construction. It must be made from interlocking half-elements, so that the cost of transport is reduced. It must be performed with juxtaposed elements of varying lengths, for the formation of an inclined bottom. Finally, it must implement small-sized devices, so that they can be injected with inexpensive presses (a few hundred tons).
- the system according to the invention comprises half-modules which can be connected to each other in one direction to form half-elements, the latter being nestable to occupy a small volume during transport, and elements of lost formwork obtained by connecting back-to-back half-elements.
- Each half-module has for example a rectangular or square shape of 0.33 m side, and some half-elements only are provided with small numbers of extension members, small and easy to connect.
- the essential element of such a system is a half-module having a plate, for example of 0.33 mx 0.33 m, provided with a cup-shaped spacer, associated with other half-modules to form a half-formwork element lost, two half-elements being arranged back to back to form a lost formwork element.
- each half-module has first connecting devices allowing a cooperation of the half-modules with each other in one direction to form half-elements, and second connecting devices allowing a cooperation of one half-modules. element with an adjacent half-piece of lost formwork.
- third connecting devices allow back-to-back connection of two half-elements for the formation of a lost wall formwork element.
- the third complementary connection devices have a positional symmetry such that only one type of half-module is required.
- the system further comprises extension members which are very simple since they are simply intended to be connected to first half-module connecting devices to extend the half-element by a length of for example 6.5, 13 19.5 or 26 cm, or 11 and 22 cm, these extension members can be cut in an extension member of rectangular or square shape, for example 0.33 mx 0.33 m.
- the invention relates to a half-module for planar flat formwork, which comprises a one-piece body which comprises a flat rectangular plate rigid enough to withstand deformation by keeping a flat surface, and a generally frustoconical spacer connected to the plate away from the outer edges of the the plate on the opposite side to the flat surface of the plate, and opening on the side of its largest section through an opening of the rectangular plate, the body comprising first complementary connecting devices disposed on two opposite first sides, and intended to connect first sides of two adjacent half-modules in position in which the second sides of these half-modules are aligned, and second complementary connecting devices disposed on the two opposite second sides, and intended to connect second sides of two half-modules; adjacent modules, and the spacer comprising third devices linkers arranged on the part of the spacer furthest from the body plate and intended to connect the spacer parts farthest from the plate of two half-modules arranged back to back, the taper of the spacer and the thickness of the body being such that two half half-

- This plate 12 is rigid and has sufficient strength to keep its flat shape under the conditions of use.
- the plate 12 has ribs 14 placed on the back.
- a large opening 16 opens into a truncated cone-shaped spacer 18.
- the section of the spacer is not necessarily circular, and it can be advantageously in the form of a quadrilateral with rounded corners.
- a central stud 20 is intended to support the center of a lid 22 shown in FIGS. 3a and 3b.
- a ventilation hole allows the passage of a gas between the two sides of the half-module.
- FIGS. 1 and 2 show first complementary connecting devices 24, 25 on opposite first sides 26 which are intended to be horizontal, these connecting devices 24, 25 being able to be put into sliding cooperation in the horizontal direction, a side 26 having a rabbet.
- the operation of connecting two half-modules by the first complementary connecting devices 24, 25 is advantageously performed in the factory, once known the length of the formwork element lost to achieve, that is to say the number half-modules of the half-formwork element lost.
- the second sides 28 of the body 10 comprise second complementary connecting devices disposed on the opposite second sides and comprising on the one hand a tab 30 having a pawl 32, and on the other hand a housing (not shown) for this tab.
- These second complementary connecting devices are intended to be placed in cooperation, preferably at the place of construction, when the formwork elements are juxtaposed.

- connection of a half-module with an adjacent half-module by the sides for the formation of a half-element the connection of a half-element with another half-element for the formation of an element, and the connection of the juxtaposed elements do not require separate connecting elements that could be lost.
- Figure 4 shows in section a part of a lost formwork element. This element is formed by connecting two half-elements by the third connecting devices, these half-elements having themselves been formed by connecting half-modules. It is noted in this figure that only the half-module intended to be turned towards the inside of the pool (bottom in the figure) carries a cover 22 carried by a pad 20. In fact, only this side must form a continuous plane. .
- half-modules described so far can be easily nested, as shown in Figure 6, so that they can be transported occupying a reduced volume.
- half-elements formed by half-modules can be nested.
- Figure 7 shows the position of the half-modules in a lost pool wall formwork.
- the pool is 0.66m deep and 1m long at one end and 2.66m deep and 1m long at the other end.
- the depth increases gradually with a slope of 0.33 m per meter.
- each extension element is flat, without spacer, and has on its large side intended to be horizontal, a connecting device (25 or 24) complementary to the third connecting device (24 or 25) on the lower side of the adjacent half-module .
- extension elements with an inclined edge depending on the slope of the pool, but we realized that it was it is preferable for the edges of the extension elements to remain horizontal, so that at one end they support the support of the lost formwork element and at the other end they release an opening for the passage of reinforcement. and concrete when it is poured into the lost formwork.
- the lost formwork elements of the intermediate portion of the wall have a flat plate-shaped extension member having a first side provided with a connecting device of the type of the first complementary connection devices, and whose size in the direction of the second sides of the half-modules is smaller than the dimension of the second sides of the half-modules.
- the invention also relates to a swimming pool construction method that allows serious cost reduction.
- the cost is reduced because the cost of transport is reduced: the half-modules or half-elements that are transported are nestable and therefore occupy a reduced volume.
- the cost is reduced because the manufacture of interlocking half-elements comprises the manufacture of reduced size half-modules, by plastic injection using weak presses.
- the cost is reduced because it is not necessary to use additional connecting members of the half-modules or half-elements, since all the connecting devices are molded in one piece with each half-module .
