• the zones B can be filled with all kinds of materials such as concrete, earth or straw. It is also possible not to fill them when the element of construction concerned does not need to present a reinforced stability.
• building sets that can contain straight and vaulted elements.
• These building sets can for example form a dwelling.
• a shuttering plate cut in half in its height can give two edge plates of the formwork 1 1.
• this relates to a method of manufacturing a building assembly 12 to 15 with a step of joining at least two plates 10, 10a disposed in the extension of one another by insertion of flat tongues 1, 3 of one in the spacings between flat tongues 3, 1 of the other; to obtain at least two first plates 10, 10a.
• the following steps of the method relate to the positioning of said at least two first 10, 10a and two second plates 10b, 10c with their inclined tongues 4, 7; 2, 7 vis-à-vis, then the insertion of the inclined tabs 4, 7; 2, 7 of said at least two first plates 10, 10a between the inclined tongues 4, 7; 2, 7 of said at least two second plates 10b, 10c, until the distal end portions 7 plane inclined tongues 4, 7; 2, 7 of said at least two first plates 10, 10a rest on said at least two second plates 10b, 10c and vice versa.
• These are preferably flat distal ends 7 of the inclined tongues 4, 7; 2, 7 which rest against the plates 10, 10a, 10b, 10c vis-à-vis.
• the inclined tongues 4, 7; 2, 7 of said at least two first 10, 10a and second plates 10b, 10c then at least partially delimit at least three zones A, B in the volume 9 between said at least two first 10, 10a and said at least two second plates 10b , 10c.
• first zone A One side of a first zone A is delimited by the inclined tabs 4, 7; 2, 7 of one of said at least two first plates 10, 10a inserted between the inclined tongues 4, 7; 2, 7 of a 10b of said at least two second plates 10b, 10c.
• the other opposite side of the first zone A is delimited by the inclined tongues 4, 7; 2, 7 of the other 10a of said at least two first plates 10, 10a inserted between the inclined tongues 4, 7; 2, 7 of the other 10c of said at least two second plates 10b, 10c.
• the first zone A is thus delimited transversely to the plates 10, 10a, 10b, 10c in the volume 9, that is to say perpendicularly to the flat tabs 1, 3 of the plates 10, 10a, 10b, 10c formwork.
• 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
• a formwork 1 1 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 in Figure 14, pallet stacking storage of a large number of plates, ensuring ease of transport, fuel economy and low footprint.
• 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 Figure 1.
• 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 the clay clay compressed, the spacing of the plates together. 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 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.
