Definitions

• the present invention relates to a formwork, of those used in construction for the execution of prismatic pillars, preferably of quadrangular section, although it could be applicable to the execution of pillars with any polygonal section, with or without its truncated vertices, formwork mono-use character, removable at the time of decoupling the column.
• the object of the invention is to provide a foldable formwork, of extreme lightness, that is served completely finished, that is to say that it does not need specialized labor for its assembly, as well as additional materials such as adhesive or similar strips, or phases of intermediate assembly, so that its final assembly on site is extremely simple, with an equiangular distribution between the vertical faces of the prism corresponding to the column or pillar to be performed, as well as facilitating the stabilization of the device in its place of placement and positioning perfectly the vertices of each column according to the orientation to be obtained.
• the outer shell generally materializes in a complex based on cardboard, plastic and aluminum, while the inner tubular core is obtained based on four cylindrical segments of high density expanded polystyrene, properly lined, either directly joined by its edges or with these substantially distanced to achieve chamfers in correspondence with the edges of the column.
• the formwork leaves the factory with a cylindrical configuration of slightly larger diameter than the diagonal of the column to be obtained, that is to say that the volumetry of the formwork is exactly the same when it is in a storage and transport situation that when it is in use situation.
• Said closure elements can be realized in webbing or in metal rings that are arranged by externally embracing the formwork.
• the fundamental problem presented by the aforementioned formwork is the complexity of assembly of said closure elements when they are materialized in metal rings, since the inner diameter of said rings must be equal to the outer diameter of the outer sheath of the tubular core, in order to that there are no gaps in its assembly, which seriously hinders the maneuvers of insertion of said rings on the envelope of the tubular core, maneuver that must be performed by qualified personnel, with the consequent loss of time and associated costs that this entails.
• closing elements are materialized in straps equipped with tensioning elements or the like, the lack of stiffness of said elements prevents ensuring the correct positioning and assembly of the formwork, the internal walls or corresponding to the prismatic pillar being able to perform not present the correct parallelism or equiangularity between their faces.
• a foldable inner tubular core participates, based on four or more cylindrical segments of lightweight thermoformed products, depending on the polygonal prismatic configuration that you want to give to the column or pillar to be made, cylindrical segments that are fixed on its externally curved face on an equally outer envelope of a sufficiently resistant and flexible material, for example raffia fabric, kraft paper, etc., of cylindrical configuration, which can adopt a flattened configuration, thanks to the joining edges of the cylindrical segments fixed thereto, segments that incorporate at least one watertight coating on its inner face in order to conveniently seal the chamber or receptacle in which the column is to be formed, which may or may not present its chamfered edges, the invention focuses its characteristics on the fact that said formwork It is supplied together with an annular, laminar piece, of configuration according to the geometry of the column or pillar to be obtained, piece obtained from cardboard, wood, plastic or any material that provides due rigidity to said element, whose interior section will present dimensions in accordance with
• the inner faces of the formwork they extend in folding eyelashes, so that at the time of the deployment of the formwork, said eyelashes are introduced inside the annular piece, so that in order for said coupling to be produced, the formwork must have the exact configuration of assembly for the pouring of the concrete or mass in question, ensuring a perfect coplanarity between facing faces of the constituent prism of the column.
• the formwork will be supplied with two annular pieces, to which the tabs that emerge from both ends of the formwork will be fitted internally, it being provided that for greater stabilization, said fins fold outwardly, on said annular piece, being fixed to it by any conventional means, such as staples, nails, adhesives, etc.
• the formwork can be fixed or immobilized to the ground through said annular pieces, preventing it from moving during the obtaining of the column in question, by shoring, with boards or any conventional means .
• said annular pieces will have markings on their surface indicating the exact positioning of each of the vertices of the pillar or column to be obtained, in order to allow the exact placement and alignment of the formwork in the rethinking of the work ensuring the parallelism between adjacent pillars.
• Figure L- Shows a perspective view of a formwork for prismatic columns made in accordance with the object of the invention, in transport or storage arrangement.
• Figure 2.- Shows a perspective view of the device in an initial phase of assembly.
• Figure 3. Shows a view similar to that of the previous figure, corresponding to an intermediate phase of assembly.

• Figure 5. Shows, a perspective detail of the mounting position of the device on its staking place.
• Figure 6. Shows, two plan views of a variant of the invention, in which the annular bodies are subdivided into two elements that can be fixed together in different positions, such as those shown in the figure, in order to allow applied on formwork of different sizes.
• the formwork that is recommended as part of the basic structure of the aforementioned formwork, constituted from a tubular core (1), which internally defines a prismatic housing (2), in the example of practical realization chosen prismatic-quadrangular, but that could adopt any other prismatic-polygonal configuration, externally cylindrical core (1), based on cylindrical segments of expanded polyurethane or other similar lightweight material, with a watertight inner lining (3), in order to conveniently seal the chamber or housing (2), said core being housed and stabilized within an envelope (4), of a sufficiently resistant material, such as based on paper, plastic and aluminum, without this product be in any way limiting, and equipped with hinge areas corresponding to the edges (5) of the prismatic column to be performed r for folding the formwork in storage or transport situation with a minimum volumetric occupancy.
• a sufficiently resistant material such as based on paper, plastic and aluminum
• the formwork of the invention focuses its characteristics on the fact that the inner envelope (3), determinant of each of the faces of the prismatic column to be obtained, extends beyond the upper and lower bases of the fin formwork (6) that in the example of practical implementation chosen they adopt an isoscelic trapezoidal configuration, but they could also adopt a rectangular configuration, without affecting the essence of the invention.
• the formwork is complemented with a pair of annular bodies (7), in this case quadrangular, in any case always with the geometry according to the section of the column to be obtained, annular body (7) laminar, obtained based on cardboard, plastic, wood or other material that has adequate rigidity, whose internal dimensions will be adequate to the dimensions of the said column, and whose thickness will be sufficient to determine the means for stabilizing the formwork, so that the The length of said fins will be appropriate to the aforementioned thickness of the annular body (7).
• the said annular bodies (7) will present marks (8) on their surface, as an extension of the inner edges of said ring, which extend to the outer edge thereof, facilitating said identification.
• the annular body (7) can be divided into two "L" shaped elements, fixed to each other by any conventional means (9), both at its ends and along its branches, in different positions, such as those shown in said figure 6, in order that said assembly can be used to adapt to formwork of different sizes, so that, in any case, by fixing said elements in "L", an annular frame of suitable section to that of the formwork in question will also be obtained, on which they can also be folded and fixed. fins (6) of said formwork.
