    The present invention relates to the field of axial tension suppression systems between a threaded rod and a nut and more particularly to axial relief devices between a nut and a spacer rod used in the context of a device for formwork.
    Currently, during the assembly and positioning of two vis-à-vis forms, these are joined by one or more spacer rods which prevent the separation of the forms by retaining them under the pressure of the concrete being set following a pouring operation.
    Conventionally, such a spacer rod passes through each of the formwork positioned vis-à-vis and is arranged to include at least one threaded part intended to interact with a nut comprising a shoulder or cooperating with a washer which is positioned in contact against the outer wall of the panel to retain the latter.
    When the concrete sets, under its thrust, the spacer rod supports an axial tension. During the stripping operation, when separating and removing the formwork, the spacer rod is always in axial tension. Under the effect of this axial mechanical tension transferred between the nut and the spacer rod, the operation of unscrewing the nut becomes difficult to carry out and the manipulator who intervenes during the stripping is obliged to force to apply sufficient loosening torque to the nut and remove the spacer rod.
    The object of the present invention is to overcome these drawbacks by providing a device for maintaining tension and releasing axial tension of a rod at the level of a nut which no longer requires a force intervention at the level of this nut. .
    [0006] The invention thus relates to a device for maintaining tension and releasing axial tension of a threaded rod relative to a frame, characterized in that this device comprises:a fixed structure adapted to be mounted fixed in rotation and in translation with a frame,a spacer disc comprising a first surface forming a bearing surface adapted to interact with a surface of a nut mounted on the threaded rod and a second surface interacting with a surface of the fixed structure via at least one ramp with a pitch opposite to the pitch of the thread of the threaded rod,a mechanism adapted to allow alternately blocking or unlocking of the rotation of the spacer disc relative to the fixed structure, the rotation blocking keeping the first bearing surface of the spacer disc separated from the fixed structure by means of at least one at least one ramp carried by the spacer disc and / or by the fixed structure, so that when the threaded rod is held in tension, the nut mounted on the threaded rod presses the spacer disc against the fixed structure, the structure fixed and the spacer disc comprising aligned orifices adapted to be traversed by the threaded rod.
    [0007] The invention also relates to a use of a device for maintaining tension and releasing axial tension of a threaded rod according to the invention to maintain and release the axial tension of a spacer rod d a formwork for pouring concrete, so that the fixed structure is mounted, directly or indirectly, against a part of a formwork element.
    [0008] The invention also relates to methods of using a device according to the invention for maintaining tension and releasing axial tension of a rod.
    The invention will be better understood, thanks to the description below, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying schematic drawings, in which:Figures 1a and 1b are schematic representations of one or more devices according to the invention implemented with a rod of a formwork element,FIG. 2 is a schematic representation of an example of a device according to the invention in voltage maintenance,FIG. 3 is a schematic representation in open view of an example of a device according to the invention in voltage maintenance,FIG. 4 is a schematic representation of an example of a fixed structure for a device according to the invention seen from the side of its face of interaction with a spacer disc,FIG. 5 is a schematic representation of an example of a spacer disc for a device according to the invention seen from the side of its face of interaction with a fixed structure,FIG. 6 is a schematic representation of an example of a housing for a device according to the invention,FIG. 7 is a schematic representation of an example of a connecting rod producing an insert part of the locking mechanism for a device according to the invention,FIG. 8 is a diagrammatic representation in section in a plane passing through the axis of rotation of the spacer disc of an example of a device according to the invention in tension maintenance,FIG. 9 is a schematic representation in section in a plane passing through the axis of rotation of the spacer disc of an example of a device according to the invention in tension release,FIG. 10 is a schematic representation in side view of an example of a device according to the invention in tension maintenance.
    The present invention relates to a device 1 for maintaining tension and releasing axial tension of a threaded rod 8 relative to a frame 7, characterized in that this device 1 comprises:a fixed structure 2 adapted to be mounted fixed in rotation and in translation with a frame 7,a spacer disc 4 comprising a first surface 4a forming a bearing surface capable of interacting with a surface of a nut 3 mounted on the threaded rod 8 and a second surface 4b in interaction with a surface 2a of the fixed structure 2 by the 'intermediate at least one ramp 5a, 5b with a pitch opposite to the pitch of the thread of the threaded rod 8,a mechanism 6 adapted to allow alternately blocking or unlocking of the rotation of the spacer disc 4 relative to the fixed structure 2, the rotational blocking keeping the first bearing surface 4a of the spacer disc 4 away from the fixed structure 2 by via at least one ramp 5a, 5b carried by the spacer disc 4 and / or by the fixed structure 2, so that when the threaded rod 8 is kept in tension, the nut 3 mounted on the threaded rod 8 presses the spacer disc 4 against the fixed structure 2, the fixed structure 2 and the spacer disc 4 comprising aligned orifices 2b, 4c adapted to be traversed by the threaded rod 8.
    The device 1 of the invention is thus adapted to form the junction between a nut 3 mounted on a threaded rod 8 and a frame 7. The device 1 is thus mounted, via the fixed structure 2, on the surface of a frame 7 and interacts by means of a bearing surface 4a with the nut 3 mounted on a threaded rod 8 arranged perpendicular to the plane of the surface of the frame 7 and against which the fixed structure 2 of the device 1 is positioned. The nut 3 is then tightened by pressing the device 1 against the surface of the frame 7.
    [0012] The nut 3 comprises an interface intended to interact with a tool to allow its tightening along the rod 8. During this tightening operation of the nut 3, the device 1 is arranged to acquire and maintain a thickness maximum. Also, prior to loosening, the thickness of the device 1 is reduced. The device removes the existing and maintained pressure between the nut 3 mounted on the threaded rod 8 and the frame 7, so that the mechanical tension between the nut 3 and the rod 8 is released. This variation in the thickness of the device 1 is made possible thanks to the presence of at least one ramp 5a, 5b between the spacer disc 4 and the fixed structure 2, the variation in the thickness of the device 1 operating during the rotation of the spacer disc 4 with respect to the fixed structure 2. Once the mechanical tension between the nut 3 and the rod 3 is released, the loosening of the nut 3 can be operated more easily.
    It should be noted that the nut 3, in addition to its threaded thread intended to cooperate with the rod 8, comprises a substantially planar surface intended to interact with the device 1 of the invention. According to a preferred embodiment of the invention, the nut 3 has a flat surface adapted to interact with the device 1 at the level of a widened surface so that this flat surface can have the shape of a disc arranged at the level of the orifice of the nut 3 mounted on the threaded rod 8 on the side of the frame 7. The “disc” surface of the nut 3 is then arranged to be in contact with the first bearing surface 4a of the spacer disc 4 .
    According to a particular construction feature, the fixed structure 2 has a substantially planar arrangement and comprising an orifice 2b intended to allow this fixed structure 2 to be traversed by a rod 8 along an axis perpendicular to the plane of the fixed structure 2 This fixed structure 2 comprises a first face intended to be able to be positioned and / or mounted against the surface of a frame 7, and a second face 2a adapted to interact with a spacer disc 4. According to a preferred but non-limiting method of construction. of the invention, this interaction with the spreader disc 4 is carried out in particular by means of at least one ramp 5a arranged on the surface 2a of the fixed structure 2 intended to interact with the spreader disc 4. This ramp 5a has a inclination in a plane perpendicular to an axis perpendicular to an axis passing through the orifice 2b of the fixed structure 2. According to an alternative explanation, a plane of this ramp 5a forms an angle with a p lan perpendicular to the axis of insertion of the threaded rod 8 in the hole 2b of the fixed structure 2.
    [0015] According to a particular construction feature, the spacer disc 4 has a substantially planar arrangement and also comprising an orifice 4c intended to be traversed by the rod 8. The spacer disc 4 comprises a first bearing surface 4a adapted to interact in pressure against the nut 3 mounted on the rod 8 and a second surface 4b adapted to interact with the fixed structure 2. The spacer disc 4 is positioned relative to the fixed structure 2 so as to be able to pivot about an axis substantially perpendicular to the plane of the disc 4 and passing through its orifice 4c. In the device 1 of the invention, the orifice 4c of the spacer disc 4 is aligned with the orifice 2b of the fixed structure 2. According to a preferred but non-limiting embodiment of the invention, the interaction of the disc 4 with the fixed structure 2 is in particular operated by means of at least one ramp 5b carried by the second surface 4b of the fixed structure 4. This ramp 5b has an inclination in a plane perpendicular to an axis perpendicular to the passing axis through port 4c. According to an alternative explanation, a plane of this ramp 5b forms an angle with a plane perpendicular to the axis of insertion of the threaded rod 8 in the orifice 4c of the spacer disc 4.
    It should be noted that when, in the device 1 of the invention, the spacer disc 4 and the fixed structure 2 both comprise ramps 5a, 5b, these ramps 5a, 5b have substantially identical inclinations. So that when the fixed structure 2 and the spacer disc 4 are each equipped with at least one ramp 5a, 5b, they are adapted to interact by sliding one on the other so as to allow a separation or bringing the first bearing surface 4a of the spacer disc 4 closer to the fixed structure 2, as a function of the rotation of the spacer disc 4 around the axis perpendicular to the plane of the disc 4 and passing through its orifice 4c.
    According to a preferred but non-limiting embodiment of the invention, the fixed structure 2 and the spacer disc 4 each comprise a plurality of ramps 5a, 5b adapted to cooperate with each other. According to a specific feature of this preferred construction, the ramps 5a, 5b are arranged around the pivot axis of the spacer disc 4 with respect to the fixed structure 2.
    According to a particular construction feature, the pitch of the ramps 5a, 5b of the spacer disc 4 and of the fixed structure 2 opposes the pitch of the tapping of the nut 3 and therefore of the thread of the rod 8 with which the nut 3 cooperates.
    According to another feature of the spacer disc 4, the latter comprises at its periphery at least one relief 4d carrying a 4th interface capable of being in contact with a stop 6a carried by a locking / unlocking mechanism 6 for prevent rotation of the spacer disc 4 with respect to the fixed structure 2. According to a non-limiting exemplary embodiment of the invention illustrated in particular in Figures 3, 5 and 8, this relief is in the form of a housing 4d positioned on the periphery of the spacer disc 4. The relief formed by this housing 4d is produced by reducing the radius of the spacer disc 4 on a corner portion of the disc 4. One edge of this housing 4d thus provides an interface 4e capable of 'be in contact with a stop 6a carried by an insertion part 6b of the locking mechanism 6 when it is inserted into this housing 4d.
    Alternatively, this housing forming relief could be positioned in a structure disposed on the first bearing surface 4a of the spacer disc 4 instead of being in the spacer disc 4 itself.
    In the absence of blocking of the 4th interface carried by the relief, the spacer disc 4 performs a full rotational stroke by sliding the spacer disc 4 on the fixed structure 2 at at least one ramp 5a, 5b. According to a non-limiting feature of the invention, the stroke of the spacer disc 4 relative to the fixed structure 2 is defined by the length of the ramps 5a, 5b and / or a possible stop limiting the travel of the rotation.
    During blocking, the blocking mechanism 6 positions a stop 6a on the stroke of the relief which carries the interface 4th, preferably at the start of the race, so that the spacer disc 4 is blocked in the spacing position by relative to the fixed structure 2.
    The release of this relief allows the spacer disc 4 to be released. Under the effect, on the one hand, of the pressure existing between the device 1 and the nut 3 in tension on the rod 8 and, on the other hand, of at least one ramp 5, the spacer disc 4 performs its stroke in rotation around its pivot axis. Unlocking then allows the first bearing surface 4a of the spacer disc 4 to be brought together with the fixed structure 2 and the tension of the nut 3 on its rod 8 to be released.
    According to a particular embodiment of the device 1 non-limiting of the invention, the locking / unlocking mechanism 6 is mounted fixed in rotation with the fixed structure 2 and comprises a stop 6a to interact with a dedicated interface 4th of the disc spacer 4 so as to allow the blocking of the rotation of the spacer disc 4 when the latter is in the position of separation from its first bearing surface 4a relative to the fixed structure 2. Such an arrangement allows an optimization of the blocking of the spreader disc 4 in relation to the fixed structure 2.
    Indeed, the locking / unlocking mechanism 6 being fixed in rotation with the fixed structure 2, the spreader disc 4 blocked by the locking / unlocking mechanism 6 is then also locked in rotation with the fixed structure 2. By Moreover, the fixing together of the fixed structure 2 and of the locking mechanism 6, also has the advantage of participating in the facilitated positioning of the elements of the device 1 on the surface of a frame 7.
    According to one particular embodiment, the stop 6a of the locking / unlocking mechanism 6 is carried by an insertion part 6b movable between a first position for locking the rotational stroke of the dedicated interface 4th of the spacer disc 4 and a second position for releasing the stroke of the spreader disc 4. According to a preferred embodiment, this insert 6b is positioned on the path of the spreader disc 4 by displacement in a plane perpendicular to the plane of rotation of the spreader disc 4 or in a plane which includes the axis of rotation of the spreader disc 4. This insert 6b can be positioned in abutment against the rotation of the spreader disc 4, by translation in the plane of rotation of the spreader disc 4 or in a plane parallel to this plane, or alternatively by pivoting about an axis parallel to this plane of rotation of the spacer disc 4.
    According to one specificity of this particularity of embodiment, the stop 6a of the locking / unlocking mechanism 6 is formed by the end of a latch. Thus, the insert 6b is carried by the end of the latch.
    [0028] According to another specificity of construction complementary to the previous specificity, the stop 6a of the locking / unlocking mechanism 6 involves a clamp 11 in its actuation. According to a non-limiting example of construction of the invention, this clamp 11 is produced by a flange 11a and a first link 6b which are each articulated respectively with a support structure of the locking / unlocking mechanism 6 and a second link 11b which connects these two pieces together. The distance between, on the one hand, the axis of articulation of the second link 11b with the flange 11a and, on the other hand, the axis of articulation of the flange lia with the support structure of the locking mechanism / release 6 is shorter than the distance between, on the one hand, the articulation axis of the second link 11b with the first link 6b and, on the other hand, the articulation axis of the first link 6b with the support structure of the locking / unlocking mechanism 6. The first link 6b then produces the insert which carries the stop 6a of the locking / unlocking mechanism 6. According to a non-limiting construction preference of the invention, the two hinge pins of the second link 11b and the hinge pin of the flange 11a with the support structure of the locking / unlocking mechanism 6 are not aligned to facilitate the disengagement of the first link 6b during pivoting of the flange 11a.
    According to a particular construction feature of the clamp 11, the flange 11a is produced by an insertion interface at which an actuating handle can be positioned. Such a construction makes it possible to limit the presence of an actuating wrist and therefore the bulk at the site of use of the device of the invention.
    According to a complementary construction feature of the clamp 11, the return to the locking position of the clamp 11 can also be helped by at least one spring 11c mounted between the hinge pin of the second link 11b with the flange 11a and the articulation axis of the first link 6b with the support structure of the locking / unlocking mechanism 6.
    According to another particular embodiment of the non-limiting device of the invention, the spreader disc 4 interacts with a restarting means 9 making it possible to drive the spreader disc 4 in rotation in the direction opposite to the ramp 5 and to position the spreader disc 4 in a position of separation from its first bearing surface 4a with respect to the fixed structure 2. According to a non-limiting example of construction, this restarting means 9 is mounted on part of the first surface 4a for supporting the spacer disc 4. Likewise, this restarting means 9 can be produced by a relief formed on the periphery of the first bearing surface 4a of the spacer disc 4 or produced by the first surface 4a, allowing a user of the device to operate a manual pivoting of the spreader disc 4 to position it in the separation position relative to the fixed structure 2.
    Thus, when the user axially rotates the restarting means 9 in the direction opposite to the direction of rotation imposed by the ramps 5a, 5b, the spacer disc 4 is rotated and positioned relative to the fixed structure 2 so as to allow the insertion of the insertion means 6b of the locking / unlocking mechanism 6 in abutment in the rotational stroke of the spacer disc 4.
    According to a preferred feature of non-limiting construction of the invention, the locking / unlocking mechanism 6 is mounted on a housing 10 whose structure at least surrounds different elements of the device 1 that are the fixed structure 2, the disc spacer 4, and / or the restarting means 9 on the first bearing surface 4a of the spacer disc 4, the structure of the casing 10 comprising a passage adapted to be traversed by the threaded rod 8 when it is mounted through the structure fixed 2 and the spacer disc 4. This casing 10 thus comprises a first portion which participates in housing all or part of the locking / unlocking mechanism 6 and a second portion which surrounds the periphery of the various elements of the device 1.
    According to another particular embodiment of the device of the invention, on the one hand, the elements of the device 1 which are the fixed structure 2 and the spacer disc 4 and, on the other hand, the nut 3 are centered on the same axis crossing each of these elements. Thus, according to this particular embodiment, the fixed structure 2, the spacer disc 4 and the nut 3 are mounted coaxially so as to be crossed jointly by the same threaded rod 8.
    Another object of the invention also relates to the application of a device 1 for maintaining tension and releasing axial tension of a threaded rod 8 according to the invention to a spacer rod 8 of a formwork for pouring concrete, so that the fixed structure 2 is mounted, directly or indirectly, against a part of a formwork element 7.
    Another object of the invention also relates to a method of implementing a device according to the invention for operating a tension maintenance of a threaded rod 8, characterized in that this method comprises at least:a step of tightening along the rod 8 of a nut 3 in contact with the first surface 4a of the spacer disc 4 to press the spacer disc 4 bearing against the fixed structure 2, the spacer disc 4 and the fixed structure 2 being kept apart by means of at least one ramp 5, so that the spacer disc 4 exerts pressure between the fixed structure 2 and the nut 3.
    Another object of the invention also relates to a method of implementing a device according to the invention for the axial retention of a threaded rod 8 characterized in that the method comprises at least:a step of unlocking the rotation of the spacer disc 4 relative to the fixed structure 2,a step of rotating the spreader disc 4 relative to the fixed structure 2 by bringing the spreader disc 4 and the fixed structure 2 closer together by sliding at least one of the two parts along at least one ramp 5 so as to operate a releasing the pressure exerted by the spacer disc 4 between the fixed structure 2 and the nut 3, and at the same time reducing the axial tension between the nut 3 and the rod 8.
    [0038] According to a feature of this axial detention method, the method also comprises:a step of implementing the mechanism for unlocking the rotation of the spreader disc 4 by removing a stop 6a from the rotational stroke of a dedicated interface 4e of the spreader disc 4.
    Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements. The scope of protection of the invention and its technical equivalents is defined by the scope of the appended claims.
