Definitions

• the present invention relates to a support with its corresponding base of support anchored to the ground, and whose support finds special application in construction, both in civil works and in buildings, constituting a resistant support means for a formwork of a civil work ( mainly viaducts) or of a building, for a loading platform, etc.
• MILLS system which constitutes a kind of traditional scaffolding, based on a series of prefabricated elements that can constitute the sides, being adjustable in height and linked to each other through diagonal bars that maintain the parallelism of the faces of the scaffolding or structure, allowing the efforts to be transmitted to the vertical support columns 5, so that at the top or top of this scaffold-shaped structure corresponding to this system, an element that can support a formwork for the realization of a building or civil work is placed.
• This structural system is very complex and occupies a large area, regardless of whether it is assembled based on prefabricated elements.
• 35 - NISSO system based on a structure with characteristics very similar to those previously mentioned, although in this system the prefabricated sides, instead of being fixed, are foldable in the form of scissors, having telescopic bars that make the mission of lateral straps to facilitate the folding of the same.
• the Spanish ES 2133076 which is entitled “STRUCTURE FOR LOAD SUPPORT" contains an invention similar to the previous one, intended to support loads, especially formwork boards and comprised of modules in parallelepiped form, stackable and adjustable in height composed of tubular elements, whose vertical edges are provided with protruding pivots on several of the faces to receive the tie rods.
• European Patent EP 0311491 for "ANDAMIAJE WITH TRIANGULAR ELEMENTS” also shows an invention relative to a scaffolding constituted by the assembly of triangular elements, each of which has a vertical tube and a snap closure of the vertical tube of an element, in the vertical tube of another triangular element.
• removable frames used for formwork support are those found in Spanish patents ES 2014124 and ES 2065205, as well as in PCT number WO 9302266.
• the support for loads and corresponding support base for its anchoring to the ground that is recommended is based on a completely removable and modular structure, greatly facilitating its transfer, with a minimum volumetric occupation both in its storage and in its transport, and what It is more important, it can be mounted without any difficulty and in a low period of time on site, to be hoisted at the same point of the work.
• the support of the invention is constituted from four vertical struts that are located in correspondence with the vertices of a hypothetical square, struts that will include at their ends four cross posters, that is to say equiangularly spaced 90 ° from each other, being able to have posters at intermediate points of the strut, depending on it.
• Said cartridges are constituted as a means of fixing the ends of the corresponding horizontal and diagonal crossbars, constituted both in one and in another case by means of tubular elements of quadrangular section, preferably, with their ends finished in pairs of lugs with holes facing each other.
• the diagonal crossbars are also fixed to the cartels established for this purpose in an intermediate zone of the horizontal studs themselves, said cartridges also having holes for fixing the lugs corresponding to the ends of the diagonal crossbars on the aforementioned cartridges, by means of the pins or corresponding bolts.
• Each module consisting of four vertical struts, with their upper and lower horizontal uprights, as well as with their diagonal crossbars, is attachable to another or other analogs until reaching the desired height, for which both the upper end and the end Bottom of the vertical struts themselves, which will preferably be of circular section, have plates, in a circular case and with holes, and in another case of quadrangular or rectangular configuration, always with holes, to allow the securing or fixing of the modules, by means of the corresponding screws.
• the support is also complemented with internal horizontal diagonals, provided precisely between the upper and lower plates of the vertical struts.
• a top terminal is mounted on the upper part, which constitutes the support means for a formwork, or for a loading platform, etc.
• That terminal auction is constituted, for each vertical strut, by a spindle topped at the top of a support head and inferiorly thereto side grip arms, constituting lever arms to actuate the spindle itself, which is complemented by a tightening nut, all so that the spindle it is located on a tubular portion of the same configuration as the corresponding struts and whose tubular portion has the same lower plate that will be superimposed on the upper plate of the upper strut, and with the cross brackets for fixing, in this case, tensioners formed by pairs of threaded rods in opposite directions on a constituent element of the tensioner itself.
• the upper support plate provided in the aforementioned terminal ends allows not only the support for a formwork, but also allows the fixing and support of determining beams of a table or platform.
• the support constituted in the manner described, with its corresponding upper end cap, also described, can be collaterally joined to other equals, being attached and joined by the respective horizontal uprights and diagonal crossbars, determining complex resistant structures.
• the support is complemented with a support base that is anchored to the ground by means of anchors that are removable and are attached to corresponding support shoes set to the effect on the ground.
• On these support shoes there is, through corresponding leveling screws, a constitutive structure of the base itself, determined by a pair of UPN profiles fixed both upper and lower between plates, the upper one intended for fixing the lower plate corresponding to the corresponding vertical strut, while the lower one is provided to rest on a leveling mortar, so that the weight does not fall on the leveling screws, but on the supporting surface that constitutes the corresponding leveling mortar.
• These profiles associated with the levelers in turn are constituted in support of other transversal profiles to them and of smaller size, on which the respective determining bars of the anchors of said support base are mounted on the corresponding concrete shoe.

• the support of the invention is constituted from a series of vertical struts (1) that are tubular and preferably circular in section.
• These struts (1) may be of greater or lesser length and be provided, both at their lower end and at their upper end, with respective groups of cartels (2-2 '), projected radially in a cross, that is to say arranged at 90 ° each other with respect to the corresponding vertical strut (1).
• This pin or bolt (7) also has a hole (10) so that once it has been introduced in the holes mentioned above, the immobilization of the anchor made by a group or similar element.
• the diagonal crossbars (5) are in turn fixed, not only to the brackets (2) of the vertical uprights (1), but to another bracket (2) provided in an intermediate zone of the vertical uprights (4), as clearly depicted in figure 1.
• (1) includes a circular plate (11) with holes (12), while at the top end there is a quadrangular plate (13) also with holes (12), to carry out the fixing of different modular supports, or which is the same different vertical struts (1) when fixed vertically one after another, as shown in dashed line in figure 1 itself.
