The panel is lined with transverse and longitudinal reinforcing members and has coupling means provided on some of the side edges and on the inside thereof for joining together the sides of two adjacent panels in the case of wall formwork, or for joining one panel perpendicularly to another panel to define the cross-section of a column by perpendicularly coupling together four panels.

Description

PANEL FOR FORMING WALLS AND PILLARS DESCRIPTION The present invention is intended to provide a panel of advantageous features for the formwork of walls and pillars. As is known, the construction of works presents the need to formwork the elements of the structure, in particular walls and pillars. At present, different types of formwork panels are available to determine the volume that the wall will occupy once the reinforcements are placed and the concrete is poured, and also panels for the construction of pillars are available in which the assembly of the pillars must be resolved. different panels forming a closed enclosure by the lateral faces that has the structure of the pillar, that is to say, usually straight prismatic, very elongated. The object of the present invention is to provide panels that can simultaneously be used for the formwork of walls and pillars. Another object of the present invention is the realization of the panels for formwork of walls and pillars simply in bent sheet metal and reinforcing crosspieces, avoiding the structures usually used of tubular type forming a frame and separately the plate that determines the face of formwork. Another object of the present invention is to provide means for quick and secure coupling of the wall panels by their side edges. Another object of the present invention is to provide means for coupling the panels perpendicularly to one another in an adjustable manner to achieve the formwork of a pillar of variable dimensions. The objectives of the present invention are achieved by the constitution of the formwork panel by means of a sheet metal element bent at the edges forming separate L-shaped profiles, to delimit the lateral edges of the formwork panel and receiving interiorly stringers and cross members also in shape of profiles, for example, U-shaped profiles, for the reinforcement of the panel and for receiving the interconnection elements of the panels laterally for the wall formwork or perpendicularly for the formwork of pillars. The connecting elements of the panels to each other are constituted by threaded rods with an arrow head that are preferably associated with two sides of the panel, allowing the joining of the panels with others adjacent to penetrate the head in the shape of an arrowhead inside a hole of conjugated form of the panel mounted in opposition, allowing its rotation to prevent its exit. The fixing of each one of the retaining elements is carried out simply by a nut with easily manipulated fins which is threaded along it and which is applied by tightening in a false bridge fixed in turn to the sides of the panel. The mentioned elements of union with the adjacent panels, composed of the rod of union with head in arrowhead and the nut of fixation fins as well as the bridge of tightening, has dimensions such that they are included in the width corresponding to the sides of the panel, so that they do not protrude transversely to the panel in order to allow easy stacking and transport. For the coupling of the panels by their side edges for the formwork of walls, it is provided that all the sides of the panel will be provided with multiple openings conjugated to the fastening elements explained, ie in a conjugate to the tip of arrow or the like of the ends of the threaded rods in order to allow the coupling of panels side by side in the desired height positions.

The fastening elements of the panels by their side edges for the formwork of walls will be arranged preferably on two perpendicular sides of the panel and will be mounted on panels off center with respect to others to prevent that when joining panels on the faces provided with fixing elements, the interference of the fixing elements of a panel with those of the adjacent one may occur. To allow the panels to be mounted perpendicularly to the wall formwork, provision is made on the internal face of the panel, that is, opposite the formwork face, of specific profiles provided with a row of openings for coupling the pointed heads of arrow or the like of the fastening elements of another panel, which in this way will allow fixing one panel to another perpendicularly to each other to delimit the prismatic space of a column. For better understanding, drawings corresponding to an embodiment of the present invention are attached as explanatory but not limiting examples. Figures 1, 2 and 3 show views of a panel showing two of its side edges and a view of the raised on the back side of the panel. Figure 4 shows a view with two panels coupled by their smaller sides. Figure 5 is a view similar to Figure 4 showing two panels coupled by their longer sides. Figures 6 and 7 show respectively an elevation view and partial section and a plan view of the panels of the invention arranged for the formwork of a pillar. As seen in the figures, the panel for shuttering walls and pillars object of the present invention comprises a sheet metal element which determines the shuttering face of the shuttering panel itself -1- rectangular shape with four sides -2 -, -3-, -4- and -5- whose structure preferably corresponds to an L-shaped profile as seen in figure 6, showing the sides -6- and -7- that, by bending of the sheet , constitutes the sides of the panel, which replace the usual tubular elements. The panel is reinforced by a variable number of crosspieces -8-, -8 '-... as well as stringers such as those indicated with the numerals -9- and -10-.

All the sides -2-, -3-, -4- and -5- of the panel are provided with multiple orifice alignments such as those indicated with the numerals -11-, -11'-, -11"-... in figure 1 and -12-, -12'-, -12"-... in figure 3. This allows the coupling of panels by their sides for the formwork of walls, as shown in figures 4 and 5, having shown in Figure 4 two panels -13- and -14-joined by its smaller sides -15- and -16- and in Figure 5, two panels -17- and -18- joined by two of its sides older -19- and -20-. The joining of two panels by their sides is preferably effected by the arrangement of coupling elements in the internal part of two perpendicular sides of the panels, as shown in figure 2, in which two fixing elements respectively have been represented. on the sides -2- and -3-, which have been designated with the numerals -21- and -21'- as well as -22- and -22'-. Said fixing devices are composed of a threaded rod -23-, figure 2, completed in a head -24- which is conjugated transverse shape of the lateral holes -11-, 11 ', -11" -... and -12-, -12'-, -12"-..., all of which are the same. The rod -23- is mounted on a support bridge -25- fixed in turn to the side panel and externally receives a robust nut -26- easy handling for tightening the clamping device whose operation is evident, since it works simply by introducing the arrowhead or the like into the hole -24- panel faced , it being retained therein after rotation, for example 90 °, of the rod, so that the head -24- arrowhead be disposed transversely to the corresponding hole, after which the tightening effected by the nut -26-. As will be understood, the specific shape of the head of the fixation device may vary between wide limits provided that the condition that its shape is conjugated to that of the hole on the side of the panel in which it is to be fixed and that its fixation has place after a turn that prevents its exit. Thus, for example, any type of hook could be used as long as it complies with the aforementioned cross-sectional characteristics of the conjugate tip of the corresponding hole shape and with holding capacity after an angular rotation to prevent its exit. Next, the means used in the panel object of the present invention will be described to allow its Formwork assembly of pillars, as shown in Figure 6 and 7. Figure 7 shows four panels coupled perpendicularly to each other, indicated by the numbers -27-, -28-, -29- and -30 - which determine a central space -31- corresponding to the desired cross section for the pillar. To allow the coupling of said panels, these internally have profiles, for example, -32- and -33-, parallel to the formwork face and provided with respective alignments of coupling holes of fastening elements in the same way as those shown in figures 1 and 3. In this way, the fixing elements of the lateral edges of a panel, for example, the panel -30- of figures 6 and 7, and which have been designated with the numerals -34- and -35-, can be inserted in the desired holes of the transversal profiles of the perpendicularly arranged panel, in the case represented by the panel -29-, the fixing being carried out in the same way as that which takes place for the lateral extension of the panels for the wall formwork. For the coupling of two panels parallel to each other, for the formwork of double-sided walls, the panels have through holes to introduce the corresponding braces, which have been indicated with the As it is understood, by means of the embodiment of the shuttering panels object of the present invention, a rational and economic manufacturing of the same is possible, as well as the same. a remarkable facility for the storage and transfer of the panels without interfere of organs to each other and likewise a big facility of adaptation so much for the shuttering of walls as for the shuttering of pillars of different dimensions. Although the invention has been represented and explained with reference to a preferred example, it will be understood that it is not limited to what has been described above and shown in the figures since any person skilled in the art, in view of what is given to know in the present invention, may introduce multiple variants that will be included in the scope of the present invention as long as they correspond to the definition of the invention according to the appended claims.
