    [0001] FIELD OF THE INVENTION The invention relates to the field of formwork, stripping processes, and methods of manufacturing portions of buildings. More specifically, the invention relates to the field of formwork. In the field of building and public works, large formwork is used to make concrete walls. These forms comprise two formwork elements, or panels, arranged face to face, and between which the concrete is poured. It is difficult to maintain vertical and stable manner during the pouring of concrete these large structures. To alleviate this problem, the applicant has proposed in FR 2 538 832 a gantry that connects the two sides together. Using such a gantry increases the stability of the assembly because the two banks are indirectly supported on each other and the overall width of the system allows a better stability. Another difficulty lies in the fact that after concrete pouring, it is necessary to separate the two panels of one another and the wall formed between them two. This spacing must be done gently so as not to damage the wall when the wall is away from the wall. In the patent FR 2,538,832 mentioned above, it then assembles the assembly formed two banches and the gantry spreader spreader which, lifted by a crane, will lead to a spacing of the two panels one of the other and the wall formed. As a result, then, the branches of the gantry deviate.
    [0002] The two panels can then be taken to another location, for example for the realization of a subsequent wall. However, the two panels are tied together by the portico, and can not be moved away from the wall in the direction of the wall. The set of rafters, the gantry and the rudder must be moved vertically or horizontally along the wall, with the berms remaining close to the wall, carefully to avoid any contact or impact between the boards and the wall that has just been formed (under conditions that may include wind). The implementation of the spreader bars is not satisfactory, the applicant had the idea to integrate the spacer function directly to the gantry. This invention was the subject of patent FR 2,700,158. This patent, which has had great commercial success, remains in use today, and is at the state of the art, with the exception of the subsequent improvement. the pivoting attachment of gantry spreaders banches, subject to its patent FR 2 808 041. Although the above patents are satisfactory, there is still the need to try to reduce the arduous work of construction site operators.
    [0003] According to a first aspect, the invention relates to a formwork comprising a first form and a second form. The first and second panels are vertical bearing on a horizontal support surface. The second side faces the first side on either side of an intermediate formwork plan. The first and second panels each comprise a formwork front face and a rear face opposite to the front face, the front faces of the first and second side facing each other. The formwork includes a portico.
    [0004] The gantry comprises a base body at the intermediate plane. The gantry comprises two branches extending on either side of the intermediate plane each between a first end connected to the base body and a second end connected to a respective wall. The branches are movable relative to the basic body between: a formwork configuration in which the second ends of the two branches are close to the intermediate plane, and. a release configuration, in which the second ends of the two branches are spaced apart from the intermediate plane. The gantry includes a linkage. The linkage comprises an actuating portion adapted to be moved relative to the base body between a low configuration and a high configuration. The linkage is connected to the branches so that placement of the actuating portion from its low configuration to its high configuration moves the branches of the formwork configuration to the release configuration. An elongate flexible member extends between a first end attached to the actuating portion and a second end having a coupling member to a lifting member.
    [0005] The second end is disposed at the rear of the rear face of one of the first and second side panels at a height of less than two meters from the support surface in a coupling / decoupling configuration. The second end being disposed above the first end in a coupled configuration.
    [0006] Thanks to these arrangements, it is possible to assemble the lifting device to the gantry without having to climb at the upper end of the gantry. The risk is therefore reduced for the operators, and the efficiency of the worksite is improved.
    [0007] In one embodiment, the second end is disposed at a height less than 1.5 meters from the support surface in the coupling / decoupling configuration. In one embodiment, the second end is disposed at the support surface in the coupling / decoupling configuration.
    [0008] In one embodiment, the second end is disposed below the level of the support surface in the coupling / uncoupling configuration. In one embodiment, the second end is disposed at a height greater than 0.5 meters from the support surface in the coupling / decoupling configuration. According to one embodiment, the first form comprises a platform and a means of access to the platform, and the second end is disposed at the rear of the rear face of the second form.
    [0009] According to one embodiment, the gantry comprises a coupling member to a lifting element.
    [0010] According to one embodiment, one of the first and second panels comprises a handling system comprising a coupling member to a lifting element.
    [0011] According to one embodiment, the handling system comprises an elongated flexible member comprising a first end attached to said box and a second end, opposite to the first end, and comprising said coupling member. According to one embodiment, the linkage further comprises a first return rod and a second return rod, mounted between the actuating portion and a respective branch. According to one embodiment, each branch comprises a deformable parallelogram with respect to parallel horizontal axes, each branch comprising a second end portion, an upper link and a lower link pivotally mounted on the base body on the one hand and on the second end portion on the other hand. According to one embodiment, each return rod is pivotally mounted on the lower link of the respective branch.
    [0012] According to one embodiment, the second end of each branch is articulated around an axis perpendicular to the intermediate plane. According to another aspect, the invention relates to a stripping process in which: a formwork is provided comprising a first banche, a second banche, the first and second 25 vertical stanchions resting on a horizontal support surface, the second banche doing facing the first side on either side of an intermediate formwork plane, the first and second side members each comprising a formwork front face and a rear face opposite to the front face, the front faces of the first and second sideboards are facing, the formwork comprising a gantry comprising: a base body at the intermediate plane, two branches extending on either side of the intermediate plane each between a first end connected to the base body and a second end connected to a respective block, and movable relative to the base body between: .. a formwork configuration in which the second ends of two branches are close to the intermediate plane, and a release configuration, in which the second ends of the two branches are spaced apart from the intermediate plane, the gantry being provided in formwork configuration, a linkage comprising an actuating portion adapted to be moved relative to the base body between a low configuration and a high configuration, the linkage being connected to the branches so that a placement of the actuating portion from its low configuration to its high configuration moves the branches From the formwork configuration to the release configuration, a lifting member is coupled to a coupling member provided at a second end of an elongated flexible member extending from the second end to a first end attached to the portion of the form. actuation, at the rear of the rear face of one of the first and second panels, in an inferior height 45 is two meters from the support surface in a coupling / decoupling configuration. The second end is moved in a coupled configuration in which it is disposed above the first end, and the further movement is continued. the second end causes the actuating portion to move from its low configuration to its high configuration.
    [0013] According to one embodiment, there is provided a method of manufacturing a building portion in which the stripping process is implemented. The figures of the drawings are now briefly described.
    [0014] Fig. 1 is a diagram corresponding to a cross-section in formwork configuration and in coupling / decoupling configuration. Figure 2 is the same section as Figure 1 in release configuration and in coupled configuration.
    [0015] Figure 3 is a magnification of the gantry shown in Figure 2. Figure 4 is the same section as Figure 1 in formwork configuration and in coupled configuration. Figure 5 is the same section as Figure 1 in the release configuration and in the coupling / decoupling configuration. Hereinafter a detailed discussion of several embodiments of the invention with examples and reference to the drawings.
    [0016] On the construction sites, we use panels 1, 2 between the faces of which is poured a concrete veil. In a formwork configuration, shown in Figure 1, the two panels 1, 2 are arranged on a horizontal support surface 4 such as a floor. Each shuttering form has a formwork face 1a, 2a. The two formwork faces 1a, 2a are turned toward each other, and define therebetween a space 5 in which concrete is to be cast in order to solidify and form a wall (in FIG. space 5 is shown filled with concrete). The two formwork faces are each substantially flat and parallel to each other. The two formwork faces are called formwork front faces, the "front", for a given form, thus referring to the position of the wall to be formed. Each panel comprises a rear face 1b, 2b, opposite to the front face. The panels 1, 2 each comprise a formwork structure 6, 7, proper, comprising the formwork surface, but may also have a number of accessories such as reinforcement means (stiffeners, beams, ...), safety devices, personnel circulation devices (such as gangway, guardrail or access ladder), stabilizing devices, leveling and leveling accessories, among others. As shown in particular in Figure 1, the form 1 comprises an upper platform 15 and a means 45 for access 16 to this platform 15 from the support surface 4, such as a ladder.
    [0017] 3035134 5 Benchs for the construction of building walls are heavy products that are not easy to maneuver on site, which requires advanced lifting equipment and ground staff.
    [0018] 5 The panels are reusable and their handling is important, especially as it is necessary to proceed to plumb and upgrades and removal of the panels after setting concrete. On the same site, it is therefore repeated in different places, in a series of operations in which we place two boards facing one another to the plumb and level in the place where a wall is to be made, the dams being stabilized. Then, pouring concrete between the formwork faces 1a, 2a of the panels to form a portion of wall in this place. Then, remove the banches to place them in another place where a portion of wall is to achieve. The stabilization of the banches can be carried out in various ways. One possible embodiment for the stabilization 15 is the implementation of an upper portal 3 which connects together two panels 1, 2 facing each other. When pouring the concrete, the boards are in close position. To release the concrete veil, the banches are spread.
    [0019] An arrangement is provided for the panels in which, on the one hand, the stabilization of the two vertical panels face to face in formwork configuration and release is provided by a device type compass, scissors or gantry and secondly , gripping and spacing of two banches are assured. To fix the ideas, it is therefore considered that the formwork surface of each formwork extends vertically in a direction Z, and horizontally in a so-called longitudinal direction Y, the direction X corresponding to the direction of the width of the formwork. The notions of "low", "high", "above" and "below" are given by reference to the vertical direction Z, the bottom being close to the support surface 4. The gantry 3 is assembled to the banches 1 and 2 above them. The gantry is more easily described in its open configuration shown in FIG. 2 (FIG. 3 is a magnification) even though, in the formwork configuration, the gantry is in fact closed (FIG. 1). Gantry 3 comprises a compass 8 having a head 9 (or base body) and two branches 10 and 11 each articulated on the head 9. The head 9 is located laterally between the two panels 1 and 2, and above those -this.
    [0020] Thus, the head 9 is located in an intermediate zone, on either side of which extend the two branches 10 and 11, each in the direction of a respective section. An intermediate plane may be defined as a plane parallel to the formwork surfaces and passing through the head 9. The branches 10 and 11 may be made symmetrical to each other with respect to the intermediate plane, as in the example presented. Alternatively, the intermediate plane is not necessarily exactly in the middle between the form surfaces, and the two branches are not symmetrical to each other. The two branches 10 and 11 are articulated on the head 9 about respective axes of rotation parallel to the form surfaces, that is to say, in this case, axes of rotation extending in the direction Y. The Branch 10 therefore extends from one end connected to the head 9 to another end connected to the block 1. The branch 10 extends in this direction downwards and outwards. The branch 11 therefore extends from one end connected to the head 9 to another end connected to the block 2. The branch 11 extends in this direction downwards and outwards.
    [0021] The branches 10, 11 are themselves formed by deformable parallelogram systems, so as to improve the vertical stability of the boards.
    [0022] The branch 10 comprises an upper link 12 and a lower link 13. The upper 12 and lower 13 rods extend substantially parallel to each other. The first ends 12a, 13a of the upper 12 and lower 13 rods are mounted on the head 9. The second ends 12b, 13b of the upper 12 and lower 13 rods are mounted on an end portion 14 of the branch 10. The montages of which These are assemblies pivoting about axes parallel to each other and parallel to the axis Y, at each of the ends 12a, 13a, 13b, 12b, so as to maintain a stable orientation of the end portion 14 when some movement. The branch 11 comprises an upper link 17 and a lower link 18. The upper 17 and lower 15 connecting rods extend substantially parallel to each other. The first ends 17a, 18a of the upper 17 and lower 18 rods are mounted on the head 9. The second ends 17b, 18b of the upper 17 and lower 18 rods are mounted on an end portion 19 of the branch 11. The assemblies of which it is question are assemblies pivoting about axes parallel to each other and parallel to the axis Y, in each of the ends 17a, 18a, 18b, 17b, so as to maintain a stable orientation of the end portion 19 when 20 some movement. A linkage 20 is used to move the branches from their formwork configuration to their release configuration. The linkage 20 comprises an actuating portion 21 and two return rods 22, 23. The return rods 22, 23 are pivotally mounted each on the actuating portion 21, and are disposed on either side of the intermediate plan. They are for example symmetrical to each other with respect to this plane. The two return links 22, 23 are pivotally mounted relative to the actuating portion 21, for example around the same pivot axis, itself also parallel to the direction Y. The return links 22, 23 are therefore connected at a first end 22a, 23a, to a rod 26 of the actuating portion 21 and, at a second end 22b, 23b, to a respective leg 10, 11. In the case where the legs 10, 11, are made as deformable parallelograms, the connecting rods 22, 23 are connected, respectively, to the lower link 13, 18, each branch 10, 11. These connections are pivotal assemblies with an axis parallel to the Y axis.
    [0023] The actuating portion 21 is slidably disposed with respect to the head 9. For example, the actuating portion 21 comprises a rod 26 extending substantially vertically. The rod 26 is guided vertically sliding relative to the head 9 between high and low positions. The actuating portion 21 comprises a coupling portion to a crane hook 28. The actuating portion 21 can thus be picked up by a hoist which also automatically and simultaneously causes the separation of the branches, and consequently banches. The end potion 14 is assembled to the banche. For example, the end portion 14 may be rigid and fixed to the banche. Alternatively, the end portion 14 may comprise two portions articulated with respect to each other along a horizontal pivot axis perpendicular to the intermediate plane (that is to say 45 extending in the X direction) .
    [0024] Referring again to FIG. 1, an elongate flexible member 24 extends between a first end 24a and a second opposite end 24b. Such an elongated flexible member 24 is for example a cable or a chain. It is tensile resistant. It is elongated in that it has a dimension in a longitudinal direction much greater than its dimensions in the other two directions. For example, it has a length of several meters, and a cross section of the order of square centimeters. It is flexible in that one can move quite widely both ends with respect to each other during normal use of the organ. The first end 24a is attached to the actuating portion 21. The fastener is for example permanent, permanent for the duration of the worksite, or removable. In the coupling / decoupling configuration, shown in FIG. 1, the second end 24b is disposed naturally, under the effect of gravity, lower than the first end, and outside the space 5. The second end 24b is in particular disposed at the rear of the rear face lb, 2b of one of the two panels. The second end 24b is easily accessible to an operator. In particular, the second end is at a height h less than two meters relative to the support surface. For example, the second end could be at a height less than 1.50 meters from the support surface to avoid a risk of shock to the head of an operator walking on the support surface. The second end could be at a height greater than 0.50 meter relative to the support surface to prevent the operator from having to bend or pull on the member 24 to take it in hand. Alternatively, the second end could rest on the support surface 4, or be at a lower height at the level of the support surface 4, if it is above the ground. In this case of panels arranged in height to make walls of high floors, the second end may be below the level of the support surface 4, at a height of less than 2 meters from the ground of the site. The second end has a coupling member 25 to a lifting member. It may especially be a hook, a ring or other.
    [0025] The hoist (not shown) has a chain or sling 27 during an arrow. The sling 27 has at its free end a lifting element 28 complementary to the coupling member 25, such as a hook or ring. The lifting element 28 may be coupled to the coupling member 25, for example manually, or automatically, if technology permits, to secure the elongated flexible member 24 to the lifting apparatus. If several gantries 3 are spaced apart from each other in the Y direction, one can provide several slings during the hoist, and each secured to a gantry. This can in particular be provided when the end portion 14 comprises two portions hinged relative to each other along the horizontal pivot axis perpendicular to the intermediate plane, thereby allowing the gantry to tilt relative to the vertical.
    [0026] The elongated flexible member 24 is sufficiently flexible so that the second end can be disposed above the first end in a coupled configuration, in which the elongated flexible member 24 is coupled to the hoist as shown In particular, the elongated flexible member 24 extends vertically in the intermediate plane.
    [0027] The actuating portion 21 may have a coupling member 29, for example identical to the coupling member 25. The coupling member 29 is compatible with the lifting element 28. The coupling member 29 is for example disposed in the intermediate plane. It is for example disposed under the portion of the actuating portion for attaching the first end 24a of the flexible member 24 to the actuating portion 45 21. Alternatively, it could be disposed above.
    [0028] 3035134 8 One of the side boards, including the second side 2, may also include a handling system 30. The handling system 30 can be coupled to a hoist to move the second side with the help of the hoist . The handling system 30 may for example comprise a chain 31 5 comprising an end 31a assembled to the second box and a second end 31b, opposite the first end 31a, and comprising a coupling member 32. The coupling member 32 is compatible with the lifting element 28. The coupling member 32 is for example identical to the coupling member 25 and / or to the coupling member 29. The handling system 30 can comprise several such spaced apart channels. One alternative to the Y axis. Alternatively, the handling system may simply comprise one or more integral coupling members of the formwork panel, for example located at the head of the formwork panel. The implementation of such a system is described below. To begin with, the rafters and the gantries are delivered to the site, and the boards are assembled two to two at a gantry on the site. It is possible to use several gantries per pair of gates, the gantries, identical or different but compatible, being spaced apart from each other in the Y direction. In the location of a first wall to be made, the gates are placed on the ground with the desired spacing corresponding to the desired width for the wall. The gantries are then in so-called formwork configuration (it may be noted that various wall widths are possible to implement with the panels, the gantry being more or less open, but this corresponds in any case to the so-called formwork configuration) . Then concrete is poured between the banches, and is allowed to solidify.
    [0029] The spacers are then moved apart from each other and from the wall. The starting situation is where the two parallel and vertical banks rest on the support surface in the close closed configuration, because, for example, a concrete wall has been made and the concrete web is sufficiently hardened, so that the we can proceed to the stripping for a new use.
    [0030] A lifting element 28 such as a crane hook can then be coupled to the coupling member 25. This coupling can be done by hand by an operator on the ground manually assembling the crane hook to the coupling member. 25, or remotely if technology permits. The flexible member is thus in the coupling configuration. It should be noted that it is not necessary to wait for the solidification of the concrete to make this coupling, the two steps being independent. The crane hook will generate a vertical upward movement of the coupling member 25, until it is above the first end 24a (Figure 4).
    [0031] Once the coupling member 25 has reached its highest point, further movement of the crane hook upwards will also cause the actuating portion 21 to be upward, so that the base body 9 will slide down relative to the actuating portion 21 under the effect of gravity. This downward sliding of the base body 9 automatically causes the branches 10, 11 to move towards their release configuration by means of the return links 22, 23 (FIG. 2).
    [0032] This provides a fast but stable spacing of the branches 10, 11, and therefore the panels 1, 2 of one another and the wall, and a distance from the ground.
    [0033] The assembly can then be taken to a new location. In this new location, the panels are placed on the ground, the first box 1 being placed in the ready position to the formwork of a new wall, 5 the gantry is open at its maximum spacing. As shown in Figure 5, the coupling member 25 is brought close to the ground 4 by the hoist. Coupling member 25 may be decoupled from the hoist by an operator on the ground. The flexible member is thus in the decoupling configuration. The hoist can couple the lifting element 28 to the handling system 30. This coupling can also be done on the ground. Following the operations prior to the completion of the formwork, once the formwork ready to be closed, 10 the separation of the panels is adjusted by operators on the ground pushing on the second panel 2 to bring it closer to the first panel 1, and place in the desired position corresponding to the width of the wall. During this operation, the second panel 2 is slightly raised from the ground by the lifting device via the handling system 30. This operation is accompanied by a rise of the base body 9, the portico taking up its formwork configuration.
    [0034] The operations which have just been exposed are carried out at each rotation of the banches. If the flexible member 24 is not available, the coupling member 29 may be used. In this case, an operator will probably climb on the platform 15. Even if the flexible member is assembled as described above, may use the coupling member 29 rather than the coupling member 25. This may especially be the case for forms made in height, for which the boom of the hoist may not be high enough to be able to déconter in using the organ 24, which is quite long. In the above examples, the connecting rods are devices of constant length, having two ends pivotally mountable. In the present document, the term "resting on the ground" means a configuration in which the soil exerts on the object a reaction corresponding to at least a substantial part, and in particular to the totality, of the weight of the object. 20 25
