  • the next step is positioning and maintaining side plates 10e to 10g on at least one non-tongue-bearing side of said at least two first 10, 10a and second plates 10b, 10c. This can be done by holding a lug 5 of each of said side plates 10e to 10g relative to its plate of said at least two first 10, 10a and second plates 10b, 10c and vice versa.
  • a formwork 11 comprising more than two first and second plates 10, 10a, 10b, 10c and possibly several side plates 10e to 10g following, it is proceeded to the repetition of the preceding steps for the positioning of additional plates in said at least two first 10, 10a and second plates 10b, 10c with formation of said at least three areas A, B whose first zone A.
  • side plates 10f, 10g additional to said at least two first 10, 10a and second plates 10b, 10c.
  • additional side plates 10f, 10g may for example be positioned relative to side plates 10e, 10f already positioned or the other opposite side devoid of flat tabs 1, 3 of the first 10, 10a and second plates 10b, 10c.
  • the present invention relates to a molded formwork plate, made of molded wood made of agglomerated particles or any other moldable product.
  • the thickness between 1 cm and 2 cm and the lightness of the plate allows, as visualized on the figure 14 pallet stacking of a large number of plates, ensuring easy transport, fuel economy and compactness.
  • the simplicity of assembly allows the implementation by any individual.
  • the plate is made by molded wood molding or any other moldable product, in the dimensions detailed in the figure 1 .
  • the assembly of several of these plates allows the realization of a formwork lost, self stabilized, to build walls, vaults or other achievements.
  • this formwork is characterized in that it comprises, by the combination of four of these identical plates, a zone A which will prevent, after filling with concrete or compressed clayey earth, the spacing of the plates between them . After hardening zones A, zones B can then be filled with all kinds of materials such as concrete, earth or straw.
  • the plate consists of 7 horizontal parts of 15 cm, 3 on one side and 7 on the other, allowing horizontal connections and two pins of 7 cm, one at the top and one at the bottom of the plate for assembly vertical.
  • the plates are fixed back to back between them by seven tabs inclined by 112 ° ending in a flat surface marked on the Figures 3, 4, 5 , 6 and 7 .
  • the two pins will be placed on the back of the high and low areas.
  • the assembly in depth is done by fixing the tabs on the plates back to back. All fixings are made by screwing the outside to the inside of the formwork with screws of more than 5 cm which will be fixed in the filling product of the formwork.
  • the method makes it possible to produce straight and vaulted dwellings.
  • a plate cut in two in its height becomes two plates of borders.
  • the Figures 12 and 13 visualize the plate in 3 dimensions.
  • the present plate is reproducible to infinity by molding process.
  • the plate is a molded formwork plate, of molded wood made of agglomerated particles or any other moldable product characterized in that it comprises, by the combination of four of these identical plates, a zone A which prevents, after filling by concrete or compressed clay soil, the spacing of the plates between them.
  • the plates are provided with seven tabs inclined at 112 ° ending in a flat surface marked on the Figures 3, 4, 5 , 6 and 7 , allowing to fix them back to back between them.
  • the plates are provided with 7 horizontal parts of 15 cm allowing their horizontal assemblies such as on the Figures 3 and 5
  • the plates are provided with two pins 7 cm at the top and bottom of the plate for vertical assembly.
  • the two pins will be placed on the back of the zone as on the figure 3 .
