    Leveling accessory to maintain the level of a horizontal formwork panel and formwork system comprising it
    Technical Sector of the Invention The present invention relates to a leveling accessory for maintaining during the assembly phase of a formwork system, the level of a horizontal formwork panel supported by a support strut. The leveling accessory is particularly suitable for the
    10 maintenance of the level of a horizontal panel that is part of a formwork system of a hanging beam (beam protruding inferiorly from a floor).
    The present invention also relates to a formwork system comprising the leveling accessory as one of its components.
    BACKGROUND OF THE INVENTION In countries or regions with seismic movements it is usual to resort to a construction typology based on walls and concrete beams to support the corresponding slabs, instead of pillars, in which the jácenas or beams are denominate
    20 of hanging for having a song superior to the one of the slab that sustain and for excelling inferiorly of the same.
    Recently, formwork systems have been developed for hanging beams formed by sections composed of two rectangular side panels arranged parallel to each other.
    25 vertical direction and joined together by a bottom panel arranged horizontally between each two side panels. The inner faces of these panels comprise a formwork surface for the concrete that will be poured to form, respectively, the side faces and the underside of the hanging beam.
    30 In the assembly of a formwork system of this type, a series of struts are placed on the ground or on the level of the concrete lower floor, on which the lower panels are arranged horizontally. Then the operators proceed to assemble the side panels by coupling them to the longitudinal edges of the lower panels (the edges parallel to the longitudinal direction of the beam to formwork). During the assembly of
    35 side panels or other elements, whose weight and effort is transmitted to the panels

    At the bottom, there is a risk that the lower panels will wobble and tip over and rotate around an axis parallel to their longitudinal axis, that is, the struts that support them do not ensure the stability of the lower panels and therefore, neither the stability of the other components of the formwork system. It should be taken into account that this situation usually occurs in the works, since the side panels are not mounted at the same time on each side of the lower panel, that is, the weight they contribute on each side to the lower panel is not compensated. It is also usual that the formwork of the hanging beam is made by having mounted a part of the formwork of the slab that will have one side, while the other is left unmounted, or that the design of the slab does not include a hanging beam that receive the same formwork loads on one side as on the other. All this generates a series of eccentric loads that contribute to the instability of the formwork system during its assembly phase, the struts being unable to ensure the horizontal position of the lower panels.
    It is worth mentioning that similar stability problems can occur in other types of formwork systems even if they are not designed exclusively for the formwork of a hanging beam, as long as there are lower panels supported on struts and are capable of receiving loads and are subject to different efforts on each of its two sides.
    For this reason, it would be desirable to have a formwork system that has a mechanism to avoid these risky situations and an accessory that could be used in existing formwork systems having to make minimal modifications to the existing formwork system to ensure stability during the assembly phase of the panels and other components.

    BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate, by way of non-limiting example, a preferred embodiment of the leveling fixture and formwork system objects of the invention. In these drawings:
    Fig. 1 is a perspective view of the leveling accessory object of the invention, in an operative leveling position; Figs. 2 and 3 correspond to a side and front view, respectively, of the leveling accessory of Fig. 1; Fig. 4 is a perspective view of the formwork system object of the invention, in which the leveling accessory of Fig. 1 is in the operative leveling position; and Fig. 5 is an enlarged view of the coupling of the leveling accessory to the lower panel of the formwork system of Fig. 4.
    Detailed description of the drawings In Fig. 4 part of a formwork system is shown for a section of a hanging beam, from which they protrude inferiorly from a floor (not shown). The part of the

    left of the formwork system is already mounted and arranged in an operative formwork position, prepared to form the concrete that is poured and thus form the lower face and the two side faces of the hanging beam (the upper face of the beam hang the joint face with the floor slab that will be concreted next or together with the hanging beam).
    As can be seen, the formwork system represented comprises for each section of the beam formwork, two lateral panels 13 arranged vertically, parallel and separated from each other by a horizontally arranged lower panel 10 whose upper face constitutes the formwork surface for the lower face of the hanging beam. In the formwork system shown, the lower panels 10 are arranged such that their longitudinal edges are in flat contact with the inner faces of the side panels 13. It is also noted that the lower panels 10 are supported by respective support struts 11 coupled to their lower faces. In particular, in the embodiment of the formwork system shown, the lower panels 10 are coupled by engagement with each other and each lower panel 10 is formed by two lower half-panels coupled to each other, one semi-panel being longer than the other, and the ones being lower half panels of shorter length which are supported by struts 11.
    In Fig. 4 And especially in Fig. 5, it is appreciated that the represented part of the described formwork system has a leveling accessory 1 to maintain during the assembly phase of the formwork system the level of the lower panels 10 supported by the struts 11. The placement of the leveling accessory 1 ensures the correct positioning and stability of the lower panels 10 and the side panels 13 to which the first ones are attached.
    In existing formwork systems devoid of leveling accessory 1, there is a problem that when assembling the formwork panels, when the side panels are placed on each side of the lower panels (supported by struts) and the slab boards that will go above of the hanging beam, the set of elements of the formwork system wobbles and tilts by rotating around an axis parallel to the longitudinal axis of the lower panels, that is, it tends to tip around an axis along the length of the beam to formwork. In fact, although the lower panels are supported by respective struts, the lower panels (and the sides coupled thereto) can rotate or bend with respect to the struts that support them. You have to keep in mind that

    During the assembly of these existing formwork systems, several operators act by assembling elements on each side of the beam. The assembly of these elements subjects the formwork panels to different efforts that are hardly compensated between the two sides, hence moments that lead to the turn towards one or the other side of the formwork assembly mounted until then, with the consequent security risk for operators and other personnel who are in the immediate vicinity of the work.
    The leveling accessory 1, shown in isolation in Figs. 1 to 3, comprises a main body 2 configured in a U-shape and which is provided with adjustment means, constituted by a wedge 6, for its lateral coupling and removable fixing to a section of the cane of the panel support strut 11 lower 10 of the formwork system. The main body 2 is formed by two parallel walls 21 joined by a base 22 that is preferably V-shaped, that is, that the base 22 is not exactly perpendicular to the walls 21 but forms an angle thereto. The walls 21 and the base 22 of the main body 2 define a lateral opening through which the main body 2 is coupled to one side of a cane section of a support strut 11 of one of the lower panels 10.
    In Fig. 1 the leveling accessory 1 is shown in the operating leveling position also shown in Figs. 4 and 5, in which the leveling accessory 1 ensures the stability of the formwork system, being fixedly coupled to a section of the shaft of the strut 11, canceling any turning or tilting movement of the lower panel 10 with respect to the strut 11 around a axis in the longitudinal direction of the lower panel 10.
    In this operative leveling position, the walls 21 of the main body 2 are arranged in a vertical plane and parallel to the plane defined by the side panels 13. On the other hand, the wedge 6 is arranged through the main body 2, closing the lateral opening of the main body 2 and thus confining a section of the strut rod 11 (not shown in Figs. 1 to 3) between the two walls 21, the base 22 and the wedge 6.
    In Figs. 1 and 2 it is observed that the two parallel walls 21 of the main body 2 are provided with respective through holes 23 whose contour defines two positioning positions of the wedge 6 depending on the diameter of the rod of the support strut 11 to which the accessory is attached leveler 1. For example, in Figs. 1 and 2 wedge 6 is placed in the position indicated for coupling to struts 11 of smaller diameter. The outline of

    the through holes 23 is designed in correspondence with the configuration of the wedge 6, which has a U-shaped section along a plane perpendicular to the longitudinal axis of the wedge 6, being configured by two parallel walls 61 joined in perpendicular direction by a base 62. The height of the walls 61 is linearly increasing from the longitudinal end of the wedge 6 that first crosses the main body 2 to the opposite longitudinal end (the one connected to the chain 9).
    In addition to the main body 2 and the wedge 6, the leveling accessory 1 comprises two arms 3 each formed by three tubular sections: a first section 32, attached to one of the sides of the main body 2 (particularly attached to the intersection zone between a parallel wall 21 and the base 22), followed by a divergent section 31 whose opposite end is connected to a third section 33. The separation distance between the two arms 3, 3 is greater between its two upper ends (the opposite ends to the main body 2) that between the lower ends that are attached to the main body 2. The divergent sections 31 make this increase in separation between the arms 3, 3 possible as they move away from the main body
    2. This variation in the separation makes it possible for the stresses received by the lower panel 10 to be channeled through the leveling accessory 1 to the strut 11 that supports it, as will be explained later. In the operational leveling position, all sections 31,32,33 of the two arms 3, 3 define a plane perpendicular to the plane that forms the lower formwork panel 10, as shown in Fig. 2 by showing that none of Sections 31 to 33 protrude horizontally.
    The upper ends of the arms 3, 3 are fixedly connected to each other by means of a cross member 5 provided with a hook means 4, formed by two hooks separated by a distance equal to or slightly greater than the distance between the upper ends of the arms 3, 3, the latter being greater than the width of the upper end plate 12 of the strut 11 (see plate 12 in Fig. 5). In the hooks that constitute the hooking means 4 it is observed that the free end of the fold of the hooks is oriented in the opposite direction to the opening of the U that forms the main body 2. This can be seen, for example, in Fig. 2 where it is seen that the hooks are bent with their tip oriented to the left, while the opening of the U of the main body is oriented to the right, side by which it will be coupled to the strut 11.
    The cross member 5 is formed by a bent L-shaped plate arranged so that the wing 51 corresponding to the base of the L is supported and joined on the upper ends 10

    of the arms 3, 3. The other wing 52, perpendicular to the wing 51, is attached on one side to the arms 3, 3, while on the opposite side the wing 52 is attached to the hooks of the hooking means 4. In the operative leveling position, the wing 51 is oriented horizontally, parallel to the plane defining the lower panel 10.
    In Fig. 1 it is observed that the wing 51 of the cross member 5 comprises at its free edge and approximately equal distance from the two hooks of the hooking means 4, a notch 53 of curved profile. The notch 53 is oriented in the same direction as the opening of the U that forms the main body 2, that is, the two open to the same side. The curved profile of the notch 53 is designed so that the notch 53 serves as a guide to favor the guided sliding of the leveling accessory 1 on the rod of the strut 11, so that the leveling accessory adopts an intermediate mounting position (not shown) before reach the operational leveling position.
    At this point it should be noted that the hooking means 4 of the leveling accessory 1 are configured to collaborate with oblong through holes 8 (see Fig. 4) provided in a rib 7 that is part of the lower panel 10, specifically of the lower face of the bottom panel 10 (opposite the formwork face that will contact the concrete). The rib 7 (see Figs. 4 and 5) is formed by a plate arranged perpendicular to the longitudinal direction of the lower panel 10, located in the vicinity of the location of the lower panel 10 in which the support strut 11 of the same. The rib 7 defines a plane in the direction perpendicular to the plane that defines the lower panel 10.
    The oblong through holes 8 of the rib 7 constitute suspension means to which the leveling accessory 1 can be engaged through its engaging means 4 and be, in an intermediate mounting position, suspended inferiorly from the lower panel 10 with the ability to swing about this. In the oblong shape of the oblong through holes 8 it has been taken into account that the area of bending of the hooks of the hooking means 4 has a greater width than the rest of the hook sections because they are manufactured by folding a portion of a rod or rod (with the tip of the free end of smaller section to facilitate entry into oblong through holes 8).
    The placement of leveling accessory 1 as part of the formwork system is explained below. It starts from the situation in which at least one lower panel 10 has been placed and the strut 11 that supports it. One or both panels may also have been mounted.

    sides 13 on each side of the lower panel 10, although it is recommended to mount the leveling accessory 1 before the side panels 13 so that when they are mounted there is no risk of overturning the assembly of the assembled formwork elements.
    The operator will take, preferably with both hands, the leveling accessory 1 with the wedge 6 out of the through holes 23 of the main body 2, orienting the lateral opening of the U of the main body 2 towards the rod of the strut 11. For example, for the position of the strut 11 shown in Fig. 5, you will take the leveling attachment 1 of Fig. 1, turn it about 1800 and tilt it forward so that the notch 53 rests on a section of the shaft of the strut 11. Next, with the leveling accessory 1 still inclined (with the part of the hooks closest to the strut 11 than the main body 2), it will slide up the leveling accessory 1 until the cross member 5 stops with the plate 12 of upper end of the strut 11 (in the case where it did not have a plate 12, it would run into the lower face of the lower panel 10 itself). When stopping, the hooks of the hooking means 4 will be in the correct position, oriented in front of the oblong through holes 8 of the rib 7 so that the free ends of the hooks cross these holes by tilting the leveling attachment 1 in the opposite direction to the one before, that is, to acquire a vertical position. At this time, when the hooks have passed through the oblong through holes 8, the leveling accessory 1 is in an intermediate mounting position, suspended below the lower formwork panel 10 with oscillation capacity with respect thereto.
    If the operator swings the leveling accessory 1, already hung from the lower panel 10 by the hooks, until it acquires a vertical position (with the wing 51 of the crossbar 5 parallel to the lower panel 10), the main body 2 will laterally surround a section strut rod
    11. Then, the operator must insert the wedge 6 through the main body 3 so that the leveling accessory 1 is removably coupled and fixed to the strut 11. At the moment when the wedge 6 is adjusted the operator can perceive that the accessory leveler 1 has reached a stable position, the operational leveling position, in which it is retained without oscillation capacity with respect to the lower panel 10, canceling any turning or tilting movement of the lower panel 10 with respect to the strut 11 about an axis in the longitudinal direction of the panel 10. At this point the contour of the through holes 8 of the rib 7 are located just receiving the support of the hooks at the point where their bending begins. On the other hand, the upper end plate 12 of the strut 11 is located above the bent L-shaped plate of the crossbar 5 and below the free ends of the fold of the hooks of the hook means 4.

    It should also be noted that in the operational leveling position, the wing 52 of the cross member 5 of the leveling accessory 1 is located on one side of the rib 7 of the lower panel 10 while the free ends of the hooks are on the opposite side of the rib 7. It is also noteworthy, as can be seen especially in Fig. 2, that the projection of the groove 53 5 on a horizontal plane parallel to the wing 51 of the cross member 5 is contained in the projection of the inner or lateral opening that forms the main body 2, it being appreciated that the deepest end of the groove 53 is separated by a certain distance from the deepest end of the inner opening of the U that forms the main body 2, that is to say the central vertex of the base 22. In fact, the distance between the deepest ends of the notch
    10 53 And of the interior opening of the U (the apex of the base 22), measured on the horizontal, is between 1.5 and 2.5 mm, preferably being a distance of 2 mm.
    The leveling accessory 1 constitutes an element that channels the stresses received by the lower panel 10, for example possible moments and eccentric loads on one of its sides 15 caused by the placement of the side panels 13 or elements that rest on the latter, towards the support strut 11, being coupled superiorly to the lower panel 10 by the hooks and inferiorly to the strut 11 by the main body 2 and the wedge 6. The separation distance of the hooks of the hooking means 4 of the leveling accessory 1, and correspondingly the separation distance between the oblong through holes 8
    20 of the rib 7, is a considerable distance that practically covers the entire width of the lower panel 10, whereby the stability of the formwork system is ensured before any eccentric load received by the lower panel 10.
