Definitions

  • the present invention is related to a crib like those used in "in situ" construction of prismatic columns, either of square section, basically square section with beveled corners, or any other polygonal section for essentially non reusable cribs, i.e., single-use cribs, which are mainly discarded when cribs are removed from columns.
  • the object of the invention is to provide a foldable crib, which considerably reduces its volumetric extension not only in storage situation, but also in transport situation; and which for its own conception allows direct use of the builder such as the manufacturer shipped it, with no need of any intermediate action.
  • one approach consists of placing an outwardly cylindrical tubular core in a sufficiently rigid tubular, cylindrical, casing.
  • the core is inwardly prismatic in correspondence to the column to build.
  • the inner surface has a coating based on a plastic film or something similar, which is suitable to avoid that humidity of the materials used in the column can damage the crib structure, while in use.
  • the outer casing is generally made with a mixture of cardboard, plastic and aluminum.
  • the inner tubular core is made with four suitably covered cylindrical segments of high density expanded polystyrene, which are joined along their edges or have them slightly spaced in order to obtain bevels that match the column edges.
  • cribs are manufactured with a cylindrical form of a diameter slightly greater than that of the diagonal of the column to build. Consequently, the crib volume is exactly the same when the crib is in storage and transport situation, and when it is in use.
  • the above explained cribs are known, in which the outer casing and the tubular core have a cut in direction of its generatrixes.
  • the cut allows storing and transporting both elements independently, and allows introducing some casings within others to minimize the space used, and to some extent also allows coating its inner cores for the same purpose.
  • this solution has a very important problem which is that the crib so structured cannot be directly used by the builder.
  • the step consists of closing the tubular core over itself, for example, using an adhesive tape placed on the peripheral zone of the edges of the inner plastic film on said core, while it is outwardly stabilized by a second adhesive tape that is generally wound helicoidally.
  • the prismatic column crib provided by the invention satisfactorily solves all above explained problems.
  • the crib specifically has an open casing along at least one generatrix and, as its main characteristic, a foldable inner tubular core. Accordingly, evident advantages associated are that the crib can take a flat form and reach an extraordinary reduction of volume and consequently of the space used when it is not in use.
  • the crib can almost instantaneously take an outwardly cylindrical, tubular form, which is stabilized when the crib is placed in its corresponding casing, which for being open is susceptible of great changes in its effective diameter.
  • a plurality of similar casings can be coaxially placed within each other by more or less deforming them, which also implies a drastic limitation of the space used by said casings or coverings.
  • the casing may have the same origin as that of the classic casings previously mentioned. Therefore, it will be kept perfectly closed in use by means of external strips or bands with a suitable strength that are conveniently arranged.
  • suitable solutions like for example semi-cylindrical metallic semi-coverings capable of being closed on each other by appropriate engagements or any other means. The only conditions are to allow a simple adaptation of the tubular core inside, to achieve a perfectly reliable and resistant closure, and to interconnect the casings with others identical in open situation so that the volumetric space used is the minimum.
  • the inner coating of the core which is made of a standard plastic and insulating film, has a tubular form with a perfectly continuous perimeter.
  • the inner coating allows folding said core because of its own characteristics, and provides a perfect superficial continuity to the crib and thus to the column to build.
  • the stabilizing casing of the core corresponding to the crib is made of a fiberglass mesh, or of any other vegetable, mineral or synthetic fabric, which gives suitable structural strength to the tubular core in working situation.
  • the stabilizing casing provides two beneficial effects for handling the crib. First, it is not used the classic semi-rigid and detachable outer casing that needs the above mentioned steps of assembling, closing and fixing in the construction place. Second, the casing made of a fiberglass mesh or something similar allows folding the core to which it is assembled. Consequently, the impact of said casing in view of the volume used during the storage and transport of the crib is practically inexistence.
  • Said foldable outer casing will be properly adhered to the rest of the crib structure by glue, thermo-welding, or any other suitable means for the type of materials used.
  • coverings are provided to avoid a residual crib deformation when they are set in the construction place after certain time in folded situation.
  • the coverings have an inner diameter coincident with the outer diameter of the crib, which has a reduced axial measure.
  • the caps are held separate from the crib itself during the storage and transport stages. Thus, they use little volume and can be easily placed on the crib at the assembly moment. Specifically, two of the coverings in the extreme zones of said crib and one or more in the intermediate zones, depending on the crib length, will make the crib take the cylindrical desired form that is necessary for a correct assembly of it.
  • Said caps can be made of any rigid or semi-rigid material so that they form a closed ring.
  • they can be made as an open ring of iron or any other similar material in combination with any conventional closing device.
  • the caps are reusable by the builder.
  • said closure can be adjustable so that the same ring or cap can be useful for cribs of different diameters.
  • said caps can have supports that help to fix the inclined supports that stabilize the crib in vertical position for its assembly.
  • the crib for prismatic columns of the present invention is formed as a conventional crib from a tubular core (1), which inwardly defines a prismatic housing (2).
  • the tubular core is squareprismatic with bevels (3) in the edges.
  • Said tubular core (1) is outwardly cylindrical and is housed and stabilized in a casing (4) also cylindrical, which is made of a sufficiently strong material.
  • the above mentioned mixture can be based on paper, plastic and aluminum.
  • the tubular core (1) is formed by four cylindrical segments (5) of expanded polyurethane or any other similar light material. It has a coating (6) that al least seals its interior in order to tightly seal the chamber or housing (2) in which a column will be built. This avoids fluid leakage and improves the finish of surface.
  • the waterproof coating (6) takes a tubular form. It offers a totally continuous peripheral closing surface that provides a perfect inner finish to the crib, which will be later transmitted to the finish of the column surface.
  • said coating (6) works as hinge for the cylindrical segments (5), not only if it has bevels (3) such as the embodiment depicted in figures, but also if it does not have bevels.
  • reference (7) designates a general crib that has been obtained in the above explained manner.
  • the casing or outer covering (4) has a cut (8) in correspondence to one of its generatrixes to allow the consequent engagement of the tubular core (1) in it.
  • Fig. 3 shows that the casing can be radially deformed through this cut because of the material used for it. This allows inserting the tubular core (4) inside the casing to obtain the engagement of several casings or coverings during storage and transport situation.
  • Fig. 3 also shows the critical reduction achieved in the volume used for said coverings (4), (4a), (4b) when they are not in working situation.
  • the casing or covering (4) that holds the tubular core (1) can be made of any material, for example metal, or can be based on two semi-cylindrical metal sheets hinged in one of their sides and can have complementary closure means on each other.
  • the outer covering or casing (4) is reusable.
  • said cut (8) allows disassembling it from the tubular core (1), which is discarded, while the outer covering or casing is reused with a new tubular core.
  • an outer webbing or strap and casing helps said covering by means of a tightening and closing element (10). In fact, it is able to keep the cut (8) perfectly closed and; therefore, the tubular covering (4) perfectly immobile like a conventional covering without said cut (8).
  • outer webbing (9) which is shown and depicted in drawings, is simply one solution within a wide series of possibilities. Hoops made of iron or any other material with a snap closure can be either used.
  • the tubular core (1) which has its inner casing (6) defining a prismatic housing (2) and the cylindrical segments (5) made of expanded polyurethane or any other similar light material, is suitable fixed to an outer casing (4').
  • This is preferably made as a flexible mesh with high mechanical strength wound it around the rest of the tubular core (1) and fixed to it by adhesive or any other means similar to the tubular, outwardly sealed, casing (6).
  • the mesh (4') additionally to mechanically stabilize the tubular core (1), allows folding said core over itself, as it is shown in Fig. 6.
  • said outer casing (4') of the mesh replaces the classic open covering made of semi-rigid material, and solves all inherent problems such as the spaced used and time spent for its assembly.
  • the crib that has a prismatic housing (2), cylindrical segments (5), bevels (3), inner casing (6) and outer casing (4) is complemented with hoops or caps (11). They replace the outer webbing or strap and casing (9) shown in Fig. 4.
  • Said caps (1) are rigid or semi-rigid, and its inner diameter matches the outer diameter of the tubular core of the crib. They are outwardly assembled to the crib in at least the outer zone of it. It is possible to have other intermediate caps (11) when the length or any other property of the crib needed it.
  • caps (1) and its rigid or semi-rigid characteristic make them recover a perfectly cylindrical outer form when they are assembled to the crib in order to have a right assembly in the construction place.
  • the assembly will be easier due to a longitudinal strip (12) extended along one of its generatrixes on the outer casing (4), which can be identified, for example, by one edge of the column to build.
