    The invention relates to a technique for producing a so-called lost formwork, which serves only a single operation, already having scrap reinforcements. It consists of a structure (2) having spacers (3) imputrescible and indispensable, on which are fixed horizontal metal irons (4) and vertical beams (5). This invention avoids the transmission of corrosion from the sheet (2) in contact with the earth, horizontal scrap (4) to the beams (5). It also allows a conventional concrete coating between the beam (5) and the sheet (2) serving as formwork, land side. On these beams (5) are fixed or inserted metal irons (6), so as to stiffen the assembly and serve to maintain the flexible screen formwork (7). The concrete is then poured between these two holding walls. This technique according to the invention is particularly intended for the construction of swimming pools and water bodies in reinforced concrete, covered with any coating. This technique according to the invention is also intended for any type of wall construction (supports or other ....)

    专利说明:

    [0001] The present invention relates to a wall formwork device in general, and swimming pool walls or water bodies in particular, rectilinear shapes or free forms. This technique makes it possible to quickly achieve the formwork, avoiding the execution of a too wide earthwork, while preserving a continuous thickness of the wall, made of reinforced concrete. The attraction of this invention lies in the originality of this formwork, said lost, which serves only one operation and already has scrap reinforcements used to strengthen the concrete. In addition, almost all of the intervention is from inside the basin.
    [0002] From patent FR 2 775 714, we know a structure for swimming pool walls comprising a galvanized sheet, a flexible retaining wall and metal beams separating the two. The concrete is then poured between the retaining wall and the galvanized sheet. This structural principle has several disadvantages.
    [0003] The first is the low life of the wall. This weakness is due to the spread of corrosion in the reinforcement, inside the concrete, by transmission of this corrosion of the sheet metal to horizontal scrap, up to the beams. It is also due to the lack of concrete coating between the beam and the formwork sheet, field side.
    [0004] The second disadvantage lies in the too great distance between the vertical beams on the one hand and between the horizontal support bars on the other hand. These too large spaces lead to deforming the flexible formwork fixed on these supports, creating corrugations on the interior finishing side, during the pouring of the concrete. This leads to an increased use of patching products to compensate for these deformations. The present invention overcomes these disadvantages. It comprises, in fact, sufficiently rigid structures on the vertical plane, either by their designs or by their thickness, having corrugations, or ribs, and sufficiently flexible on the horizontal plane. The products used are mainly galvanized sheet or polycarbonate or polyester or plastic or recycled products or any other product. -2- On the inside of the semi-rigid structure, rotable and essential spacers are attached to the formwork at each beam, which allows a perfect coating of scrap in the concrete. Without these wedges, the reinforcement would therefore be too close to the formwork, would inevitably cause corrosion of the reinforcement and make the structure unconventional and brittle, because of the lack of concrete coating around the scrap. Almost all of these structures used are already rot-proof by design and are therefore not subject to corrosion attacks. The only product that is vulnerable to these attacks is the galvanized sheet. These rotable spacer blocks gives it an anti-corrosive barrier and because of this wedge, all other components, named above and likely to be used, remain in their entirety safe from this corrosion. These shims fixed with screws or clips or welds or collages or metal ties or staples are scalable; their thickness, their numbers and their sizes are flexible according to the needs, with as imperative, the obligation to be rotproof and to allow the conventional and indispensable coating of scrap in the concrete. It is obviously possible to obtain these wedges, integral with the structure, during the manufacture of the latter. On these wedges are fixed, with any method of attachment that is, several horizontal metal bars, twisted irons or other, of different diameters, with a regular spacing and variable, depending on the heights. These bars serve to stiffen the horizontal flexibility of the structure and serve as supports, in addition to spacers, for the vertical attachment of steel beams or any other product, using screws or clips or welds or collages or 25 metal ties or staples or other attachment system. These bars can be fixed also to the structure, under the holds or on both sides of the holds. The spacing of these beams varies according to their diameters, their sizes, the height of the building and according to the maintenance needs of the inner flexible formwork. These beams are triangular, square, rectangular or other, depending on the needs and constraints and are fixed on shims or metal bars. According to another holding possibility, these bars can be positioned outside the structure, on the ground side, by fitting into a small part of the spacers provided for this purpose, passing through the structure, and the other part, the most important, plated inside the structure. These bars would therefore strengthen the horizontal flexibility and serve to fix spacers.
    [0005] The modules are attached to each other by vertically overlapping the two sides of the walls, or by using a connecting piece, using screws or clips or welds or collages or metal ties or staples or any other attachment system, so as to close the structure on the entire perimeter of the basin. On the opposite side of the beams, are fixed horizontally metal bars in twisted irons or other products, of different diameters, adjustable spacings or according to the needs of maintaining the flexible formwork, using screws or clips or welds or collages or metal ties or staples or other fastening system. It is also possible and interesting to simply pass these bars inside the beams, so as to have a mechanical support during the thrust of the concrete and an effective coating of scrap. The replacement of the bars with welded mesh panels is also feasible, with binding required on the vertical beams, with reinforcement of horizontal bars, if necessary. The formwork is fixed on the vertical and horizontal supports, spaced according to the needs of maintaining the formwork and taking into account the deformation of the latter during the pouring of the concrete. This flexible formwork with small mesh, different sizes and diameters is made of steel, galvanized steel or polyethylene or polycarbonate or plastic or polyester or recycled product or any other product. The accompanying drawings illustrate the invention: FIG. 1 shows the straight (2a), ribbed (2b), or corrugated (2c) structure with the spacers and the metal bars attached to the structure or on the holds . Figure 2 shows the structure of different shapes with the spacers 30, metal bars, vertical beams and metal bars fixed to the beams or inserted inside. Figure 3 shows the complete structure, with grid formwork. FIG. 4 represents a plan view of the complete ribbed structure. FIG. 5 represents a complete view of the straight (2a) or corrugated (2c) structure with the possibilities of triangular (5) or square (5a) or rectangular (5b) beams fixed on the horizontal metal bars.
    [0006] Figure 6 shows a top view of the complete structure, with fixing wedges and reinforcement of the structure, from behind, on the other side of the formwork, with the horizontal metal bars. Figure 7 shows a sectional view of the complete structure. With reference to these drawings, the invention is characterized by the placement of supports 10 in twisted irons diameter 10 or 12 planted in the ground or the creation of a concrete support, only on the space intended to receive the wall after having excavated the excavation. A concrete cleanliness can also be implemented on the whole bottom of the basin. Unwinding and laying of the structure on the supports, if this wall is in one piece. For structures composed of several portions, arrange the parts on the concrete supports, previously made. These structures (2) are sufficiently rigid vertically, either by their thickness (2a), or by their design (2b, 2c), and sufficiently flexible on the horizontal plane. The outside of this wall is positioned on the side of the natural terrain and will serve as support for the embankments (1). It is even possible to backfill the entire formwork, before pouring the concrete. On the inside of the semi-rigid structure, rotable and indispensable spacers (3) are attached to the formwork at each joists; their thicknesses and their sizes are flexible according to the needs. 25 On these wedges are fixed, with any method of attachment that is, several horizontal bars (4), twisted irons or other, of different diameters, with a regular and variable spacing. These bars serve to stiffen the horizontal flexibility of the structure and serve as supports for the vertical fixing of steel beams. These beams (5) are triangular, square, rectangular or other, depending on the needs and constraints. -5- Once all these modules are positioned on the concrete support, fix vertically, overlapping the two parts of the walls or using a connection piece. Repeat the operation by fixing the walls to each other, so as to close the structure on the entire perimeter of the basin.
    [0007] Also check for leveling and leveling, by supporting the structure. Position the water circulation pieces, taking care to pass all the necessary pipes and especially to protect them by the passage in ducts. On the opposite side of the beams, horizontally fix metal bars (6) of different diameters and adjustable spacings.
    [0008] It is also possible and interesting to simply pass these bars inside the beams, so as to have a mechanical support during the push of the concrete and an effective coating of scrap. Make the low chaining inside the basin, all around the perimeter, using twisted irons of different diameters, shaped on demand, and ligate them together. Outside the basin, at the top of the structure, make a wider formwork, if necessary, with the same materials as the structure, using twisted irons of different diameters, shaped on demand and ligate together. Unwind the small mesh (7) inside the basin and fix it on the 20 vertical and horizontal supports. Leave a space of about 12 to 18 cm, or any other distance as needed, at the bottom of the formwork to allow the concrete to descend and bond with the raft. Perform the reinforcement of the slab, in twisted irons of diameter 8 or with welded mesh panels, and ligate the assembly to the inner chaining of the basin 25 provided for this purpose. As an alternative to the reinforcement, use a concrete with metal fibers. Pour the concrete into the formwork up to the chaining, then pour the raft of the basin over a thickness varying from 12 to 15 centimeters. Think to float the whole.
    [0009] 30 It is possible to design concrete structures inside the pool, such as stairs, balneo benches, submerged beaches ....... -6- After cleaning the pool, create around all the sealed parts a seal and expansion, using suitable products. All that remains is to cover all the concrete parts with a water-repellent coating, and then a finishing coating (silico-marbled type, tiling, mosaic, epoxy paint, resin mortar or similar ...) or Liner, after a cleaning full. The device according to the invention is particularly intended for all forms and all kinds of concrete formwork.
