In this example, without this limiting the scope of the present invention, part of the form (1) is covered with soil, plants, decorative vegetation and mixtures thereof. In this way, without this limiting the scope of the present invention it is possible to obtain structures with decorative features.

[0051] The present invention satisfies the need to provide an effective, agile and cost-effective mechanism to build retaining walls and various types of complementary applications, of superior resistance and stability, which in turn, are susceptible of being covered with soil, different types of plants, decorative vegetation and mixtures thereof.

[0052] The description of the modality of the present invention is not intended to limit its scope, but rather to serve as a particular example thereof. A person skilled in the art is expected to understand that the equivalent modalities do not depart from the spirit and scope of the present invention in the widest extent possible.

[0053] For a better understanding of the present invention, certain technical terms used in its description will be detailed below.

[0054] In the context of the present invention, “form” will be understood as the system that functions as a set of casting chambers, understood as modules or molds, in which the concrete and other materials are poured.

[0055] The concrete or other materials are poured into the form where the setting or drying process takes place.

[0056] The form (1) object of the present invention comprises a plurality of terminal structural elements (2) that carry a plurality of assembly channels or cavities (7); a plurality of main structural elements (3) that have a plurality of perforated holes (6) inside and a plurality of assembly channels or cavities (7); and a plurality of cross elements (4) that have a plurality of assembly channels or cavities (7) and that are connected transversely to said terminal structural elements (2) and to said main structural elements (3) by means of said assembly channels or cavities (7), creating casting chambers (5). Additionally, said casting chambers (5) are interconnected with each other, through said perforated holes (6) in the main structural elements (3).

[0057] In a preferred modality of the invention, said terminal structural elements (2), said main structural elements (3) and said cross elements (3) that are part of the form (1), object of the present invention, are manufactured from a lightweight material that can be selected, for example, and without limiting the scope of the present invention, from the group consisting of cardboard, corrugated cardboard, wood, plastic wood, metals, aluminum, rigid polyethylene plastics, polypropylene, nylon, Teflon, PVC, methacrylate, and rigid laminate materials, as well as combinations thereof.

[0058] With respect to said terminal structural elements (2) and said main structural elements (3), they can have any shape imagined by a person with average knowledge in the technical field without this limiting the scope of the present invention. In a preferred modality, the surface of said terminal structural elements (2) and said main structural elements (3) may have the shape of polygons, orthogonal polygons, pentagons, hexagons, warped polygons where the sides do not meet on the same plane, and figures composed of lines and curves arranged in a three-dimensional space.

[0059] In a preferred modality of the invention, the form (1) is applied to build retaining walls. In this preferred modality, without this limiting the scope of the present invention, the form (1) is made up of terminal structural elements (2), main structural elements (3) and cross elements (4) that are previously laser cut or die cut. This preferred modality, for example, and without limiting the scope of the present invention, allows said terminal structural elements (2), said main structural elements (3) and said cross elements (4) to form the casting chambers (5) in a staggered pyramidal shape, creating various geometric shapes.

[0060] In another preferred modality of the present invention, without this limiting the scope of the requested protection, the assembly channels or cavities (7), which are present in said terminal structural elements (2), said main structural elements (3) and said cross elements (4) are previously laser cut or die cut. This preferred modality, without this limiting the scope of the present invention, has the advantage that said laser cutting or die-cutting allows said assembly channels or cavities (7) to be given a special geometry that adapts precisely to the shape of the structure to be reinforced or contained. In this way, without limiting the scope of the present invention, said terminal structural elements (2), said main structural elements (3) and said cross elements (4) can be coupled with each other with much precision and allow the form (1) that is the object of the present invention to grow in a modular fashion as necessary, as shown schematically in FIG. 8.

[0061] As previously mentioned, the main structural elements (3) that are part of the form (1) that is the object of the present invention, comprise perforated holes (6) that join together the casting chambers (5) defined in the form (1). Said perforated holes (6) allow the dumping to be connected through the different casting chambers (5) to create the desired geometry of the form (1) in a monolithic structure.

[0062] As shown in FIG. 3, the cross elements (4) are connected transversely to the terminal structural elements (2) and/or to the main structural elements (3). For this, internal assembly channels or cavities (7) are provided, which allows, in this way, to form the respective casting chambers (5), providing the necessary rigidity to the form (1) object of the present invention.

[0063] The form (1), object of the present invention has various types of geometries with different inclination angles. This is as foldable, be prefabricated, self-supporting, tailor-made form, cut or die-cut in series; it does not require glue or any type of adhesive, and it is made from light and cost-effective products.

[0064] In a preferred modality of the present invention, without this limiting its scope, the geometry of the form (1) is ensured by means of an assembly or joining element present in at least two of the form terminal structural elements (2) or the main structural elements (3) (1). Said assembly or joining element comprises internal assembly cuts (8). Additionally, in this preferred modality, at least one of the cross elements (4) has fixing and coupling elements (9) matching said internal assembly cuts (8); for example, but not limited to, projections that ensure the desired geometry and then allow the dumping process being shaped up with the respective architecture, creating a monolithic body result.

[0065] The internal assembly cuts (8) are presented in the folding form (1) object of the present invention depending on the shape of the casting chambers (3).

[0066] As shown in FIG. 9, in a preferred modality of the invention, without this limiting the scope of the present invention, said fixing and coupling elements (9) may have a T-type or arrow shape.

[0067] As seen schematically in FIG. 10, and without this limiting the scope of the present invention, in a preferred modality the form (1) can have stiffening elements (10). Said materials may be inside said form (1) and perpendicular to the main structural elements (3). In a more preferred modality, as shown in FIG. 10 and without this limiting the scope of the present invention, the form (1) may have a stiffening element (10) located as a central bond (11) functioning as a tension member. Both the stiffening elements (10) and the central bond (11) can operate as a beam, without this limiting the scope of the present invention. The stiffening elements (10) and the central bond stiffening element (11) can be made from the same material of the terminal structural elements (2), the main structural elements (3) or the cross elements (4) that make up the casting chambers (5) of the form (1).

[0068] Examples of application of the form (1) object of the present invention will be described below. Said examples are intended to provide a better understanding of the invention, but do not limit its scope. Additionally, technical characteristics described in different examples can be combined with each other, or with any of the previously detailed technical characteristics, in any way imagined by a person with average knowledge in the technical field, without limiting the scope of the present invention.

Application of the Form to Build Retaining Walls

[0069] The form (1) can be assembled and subsequently be subject to a casting process without surrounding elements; or it can be abutted against a curved or flat surface to act as a retaining wall or construction wall.

[0070] The resistance of the retaining walls will depend on the casting material chosen. The walls can be covered with concrete, soil, natural gardens, sand, straw, wood and all kinds of exterior finishes.

[0071] The dumping into the form must be done on a firm and compact floor. The form (1) is quick and easy to assemble and dumping is completed in a few hours. For the particular case of the construction of retaining walls, the geometry of the form (1) must be based on stepped molds, thus resulting in an inclined wall that offers much greater retaining strength than a vertical wall.

[0072] The dumping process is carried out in layers, step by step. Each layer must undergo the corresponding setting or drying process before the subsequent layer is poured.

[0073] In the case of a (1) corrugated cardboard form, the dumping takes place in 5 to 100 cm layers. These values may be modified according to the material used in the manufacture of the form (1).

Other Applications

[0074] The form (1) can have various applications, such as stair casting, construction of living spaces, porches, columns, furniture construction (FIG. 12) and all kinds of architectural forms for practical or decorative use.

[0075] The casting chambers (5) of the form can be made of non-degradable material and can be used as cultivation beds, for which they can be filled with fertile soil (FIG. 13).

[0076] In addition to the consequent pouring with concrete, the casting chambers of the form (1) can be covered with natural soil or fertile soil and different types of vegetation (FIG. 14).

[0077] Although the present invention has been described with the preferred modalities shown, it is understood that any modification or variation that retains the spirit and scope of this invention is intended to be within the scope of the appended claims.
