    [0001] FIELD OF THE INVENTION The present invention relates to the field of formwork and, more particularly, to a shuttering formwork. Forms are already known comprising a plurality of panels between which is poured a hardener material such as concrete. Referring to Figure 1, such a formwork blank 101 comprises a vertical wall 102 whose formwork front face 102A is intended to be disposed internally to the formwork and to be in contact with the material cast therein. Ordinarily, the formwork comprises a platform 103 mounted on the upper part of the mold 101 to allow the circulation of one or more operators in order, for example, to inject the hardener material into the formwork. To allow an operator to climb on the traffic platform 103, the board 101 conventionally comprises a vertical ladder 104 mounted under the platform 103 and opening into a passage opening 131 formed therein. The wall 101 also includes a hatch (not shown) for closing the passage opening 131. To secure the movement of an operator on the platform 103, the latter conventionally comprises railings 133. During the operations of formwork, an operator must go up and down many times the scale 104 of the board 101, which increases the difficulty of the operators. The arduousness of the operators is increased when several banks are superimposed vertically, the operators then having to ascend / descend successively a plurality of scales 104. In order to solve this drawback, it has been proposed by the Applicant to provide a mobile traffic platform vertically. Nevertheless, such a solution is expensive to implement. In order to eliminate these drawbacks, the invention relates to a shuttering panel comprising a vertical wall comprising a formwork front face, an upper circulation platform comprising a passage opening and a ladder adapted to allow the shuttering to be carried out. access to the upper traffic platform via said passage opening. The form is remarkable in that the scale is inclined relative to the vertical direction of an inclination angle of 15 ° and 30 °.
    [0002] Thus, advantageously, getting up and down from the traffic platform is less painful for those skilled in the art as compared to a vertical ladder. This is particularly advantageous when an operator must access the platform of circulation of a branch superimposed vertically on several other banks.
    [0003] Preferably, the scale extends longitudinally along an axis parallel to the vertical wall in the use position. Thus, the vertical wall prevents a lateral fall of the operator when it moves on the scale parallel to the vertical wall. Likewise, guardrails can prevent the fall of operators from the side opposite the vertical wall. Finally, the overall size of the ground handrail remains unchanged from a blank according to the prior art since the ladder extends under the traffic platform. Preferably, the ladder includes a plurality of flat steps to improve the stability of the operators during ascent or descent. Advantageously, the steps are horizontal to limit the arduousness and improve the stability of the operators. Preferably, the flange includes ladder linkage means to the upper traffic platform which are configured to move the ladder between a use position and a storage position. Thus, the ladder can be moved to free a working space for the operators (clamping between boards, spacers, etc.). Only one of the amounts is articulated, the other being mounted free.
    [0004] Preferably, the scale extending in a plane, the plane of the scale is in a vertical plane in the storage position. Thus, the operator can perfectly circulate under the traffic platform, the footprint of the ladder being reduced.
    [0005] According to a preferred aspect, the connecting means are configured to position the ladder in the storage position in a vertical plane which is remote from the vertical wall, preferably in the plane of the outer edge of the traffic platform. An operator can move freely between the vertical wall and the ladder to access the various equipment. In addition, the ladder forms a protection in the event of a fall to the rear. Preferably, the formwork comprises means for locking the ladder in the storage position. The operator does not have to maintain the ladder in the storage position, which is advantageous.
    [0006] Preferably, the ladder comprises release means adapted to unlock the ladder of said locking means in the storage position. Preferably, the release means are integrated in an amount of the scale. According to one aspect of the invention, the release means comprise a rod mounted in the upright. According to a preferred aspect, the ladder comprising two parallel uprights connected by a plurality of steps, the connecting means are configured to articulate one of the uprights to the upper platform of circulation along an axis of articulation parallel to said upright, preferably along a coaxial axis. Thus, the scale can turn conveniently using one of its amounts as axis of rotation, the other amount being free. The displacement of the ladder between its position of use and its storage position is thus easy and practical.
    [0007] Preferably, the connecting means comprise resilient means configured to drive the scale from its storage position to its position of use. Thus, after unlocking, the scale is automatically moved to the use position because of the action of the elastic means, which provides a time saving.
    [0008] Advantageously, the upper circulation platform having a hatch adapted to close the passage opening, the connecting means are configured to lock the hatch in the closed position when the ladder is in the storage position. Thus, an operator can not open the hatch if the ladder is not in the position of use, which limits the risk of accident. Preferably, the locking means are integral with the traffic platform. Preferably, the locking means are adapted to be deactivated from the traffic platform. Thus, an operator located on the traffic platform may release the ladder. This is particularly advantageous when the connecting means comprise elastic means, the scale moving autonomously to its position of use. The operator can safely descend from the traffic platform.
    [0009] Preferably, the ladder is removably mounted to the upper circulation platform so that it can be removed when transporting the board to the storage position. According to one aspect of the invention, the ladder comprises at least one telescopic foot so as to be in contact with floors or decks of different heights.

    [0010] DESCRIPTION OF ONE OR MORE EMBODIMENTS AND IMPLEMENTATION With reference to FIG. 2, there is shown a shuttering box 1 according to one embodiment of the invention.
    [0011] The panel 1 comprises a vertical wall 2 whose formwork front face 2A is intended to be disposed internally to the formwork and to be in contact with the material cast therein. For example, the form surface 2A is steel, stainless steel or plywood. Still with reference to FIG. 2, the casing 1 comprises a circulation platform 3 mounted in the upper part of the casing 1 to allow the circulation of one or more operators in order, for example, to inject the hardener material into the formwork . The circulation platform 3 has a passage opening 31 which, in this example, has a rectangular shape in order to allow an operator access to the upper surface of the traffic platform 3. The traffic platform 3 also comprises a hatch 32 adapted to close the passage opening 31, the hatch 32 being hinged at the upper surface of the circulation platform 3.
    [0012] According to the invention, the panel 1 comprises a scale 4 adapted to allow access to the upper circulation platform 3 via said passage opening 31. As illustrated in FIG. 2, the scale 4 is inclined with respect to the vertical direction of an inclination angle [3 between 15 ° and 30 ° so as to limit the difficulty of an operator during its rise or descent.
    [0013] As shown in FIG. 2, the scale 4 extends axially along an axis XE and comprises two longitudinal and parallel uprights 5 which are connected by horizontal steps 6. The steps 6 are flat in order to allow a rise / fall 5 stable and practical. Such a ladder 4 is referred to as a "miller's ladder". Subsequently, the longitudinal amounts 5 of the scale 4 define a scale plan. Subsequently, the amount 5 of the scale 4 farthest from the vertical wall 2 is designated "rear amount" while the other amount 5 is designated "amount before".
    [0014] The ladder 4 comprises a head 4A connected to the upper circulation platform 3 and a foot 4B adapted to rest on the ground or on an upper platform of circulation when several boards are superimposed vertically. The foot 4B is advantageously telescopic to allow the ladder 4 to come into contact with floors or traffic platforms of different heights.
    [0015] In this embodiment, again with reference to FIG. 2, the panel 1 comprises connecting means 7, connecting the ladder 4 to the upper circulation platform 3, which are configured to move the ladder 4 between a position of use P1 (Figure 2) and a storage position P2 (Figure 3). With reference to FIG. 2, in the use position P1, the axis of the scale XE extends parallel to the vertical wall 2, that is to say, laterally to section 1. L ladder 4 extends entirely under the traffic platform 3 so that the footprint of the building 1 remains unchanged from the prior art.
    [0016] With reference to FIG. 3, in the storage position P2, the plane of the ladder is in a vertical plane in order to free up the space under the traffic platform 3. This is particularly advantageous when several boards are superimposed vertically like this. will be presented later.
    [0017] In this embodiment, with reference to FIGS. 4 and 6, the connecting means 7 are mounted between the rear pillar 5 and the upper circulation platform 3. The connecting means 7 are configured to allow the rear pillar 5 to rotate. relative to the upper circulation platform 3 about a first axis X1 which is coaxial with the axis of the upright 5. In other words, between its use position P1 (FIG. 2) and its storage position (FIG. ), the scale 4 can rotate 90 °.
    [0018] Advantageously, the connecting means 7 are configured to allow the rear post 5 to rotate relative to the upper circulation platform 3 around a second axis X 2 which is perpendicular to the vertical wall 2 in order to allow adjust the degree of inclination of the scale 4 as illustrated in FIGS. 6 and 8. According to this embodiment, with reference to FIGS. 4 and 6, the connecting means 7 comprise a cylindrical connecting element 70 in which is inserted the upper end of the rear pillar 5 to articulate along the first axis Xl. Pins 71 are provided to prevent the upper end of the rear upright 5 from being withdrawn from the cylindrical connecting element 70. Preferably, the connecting means 7 comprise elastic means, in particular a torsion spring, adapted to to constrain the ladder 4 in its use position Pl. In this example, a torsion spring (not shown) is mounted in the cylindrical connecting member 70. The connecting means 7 are also configured to lock the hatch 32 in the closed position when the ladder 4 is in the storage position. P2. For this purpose, with reference to FIG. 8, the upper end of the rear pillar 5 is connected to a locking element 72 which is adapted to block the hatch 32 when the ladder 4 is rotated around the axis X1 to its storage position P2. In this example, the locking member 72 has the shape of a locking finger but it goes without saying that its shape could be different. An operator can thus not fall through the passage opening 31 when the ladder 4 is not in the use position P1. The other post before 5 is free mounted and is not connected to the platform 3. Preferably, the circulation platform 3 comprises stop means 73 for locking the front upright 5 in the position of use as illustrated in FIG. 8.
    [0019] Still referring to FIGS. 4 and 6, the cylindrical connecting element 70 is articulated with respect to the circulation platform 3 about the second axis X2 which is perpendicular to the vertical wall 2. Thus, the ladder 4 can move between its use position P1 and its storage position P2 by virtue of the first hinge axis X1 for any inclination of the ladder 4 defined by the second hinge axis X2. The connecting means 7 are connected near the rear edge of the traffic platform 3 so that, in the storage position P2, the ladder 4 extends vertically and is substantially aligned with the rear edge of the platform Thus, the space at the rear of the vertical wall 2 is clear to allow operators to access the various equipment of the section 1 (shore connection equipment, connecting struts, etc.). In addition, the traffic of the 10 operators is secured since the ladder 4 forms a protection against falling backwards. Preferably, with reference to FIGS. 4 to 6, block 1 also includes locking means 8 of scale 4 in storage position P2. The locking means 8 are integral with the circulation platform 3. In this embodiment, with reference to FIGS. 4 to 6, the locking means 8 comprise a lower member 81 which is adapted to cooperate with the front pillar 5. the scale 4 in order to block it in storage position P2. As illustrated in FIG. 5, the lower member 81 has a cam portion for guiding the front post 5 and an abutting portion for blocking it when it has reached the storage position P2. In this example, with reference to FIG. 6, the upper end of the front upright 5 comprises a connecting member 51 adapted to cooperate with the lower member 1. Preferably, the connecting member 51 has an annular shape but it is self-evident that it could be of different form. The locking means 8 also comprise an upper member 82, connected to the lower member 81, which extends at the upper surface of the circulation platform 3. With reference to FIG. 5, the locking means 8 comprise Also a tension spring 83 adapted to constrain the lower member 81 downwards. As the upper member 82 is also connected to the lower member 81, the tension spring 83 is also adapted to constrain the upper member 82 downwards. Advantageously, the upper member 82 is shaped like a handle to allow an operator to release the front leg 5 of the ladder 4 by pulling upwards.
    [0020] When the ladder 4 is in the use position P1, the upper member 82 is in the low position. When the ladder 4 is in storage position P2, the front upright 5 presses vertically upwards on the lower member 81 by opposing the force of the pulling spring 83, which moves the upper member 82 in high position. Advantageously, from the traffic platform 3, an operator can unlock the ladder 1 by acting on the upper member 82 upwards to move the lower member 81 and release the front post 5 of the ladder 4.
    [0021] Preferably, the ladder 4 comprises release means 9 adapted to release the ladder 4 of said locking means 8. Thus, an operator located under the traffic platform 3 can return the ladder 4 to its position. With reference to FIG. 7, the release means 9 are integrated in the front post 5 of the ladder 4 and are adapted to move the connecting member 51. For this purpose, with reference to FIGS. 8, the release means 9 comprise a handle 91 connected to the connecting member 51 via a rod 92 mounted in the front upright 5 to allow an operator located under the circulation platform 3 to separate the connecting member 51 from the lower member 81 of the locking means 8. In other words, the ladder 4 can be unlocked from its storage position P2 to be returned to its use position P1. Preferably, the handle 91 is at a height ergonomic for the operator. Preferably, the ladder 4 is removably mounted to the circulation platform 3 in order to allow it to be withdrawn when the blank 4 is folded back into the storage position P2. An example of implementation of the invention will now be presented for two vertically stacked 1 vertices. The ladders 4 of the boards 1 are in the use position Pl, their inclination and the length of the legs 4B having been previously adjusted so that the foot 4B of the lower ladder 4 is in contact with the ground while the 4B foot of the upper scale 4 is in contact with the upper traffic platform 3. To access the traffic platform 3 of the upper tray 1, the operator 35 mounts the lower scale 4 in the use position Pl and It passes through the opening 3035133 10 passage 31 in order to be positioned on the circulation platform 3 of the lower panel 1. Due to its inclination, the rise is convenient, not tiring, and fast.
    [0022] The operator can move the upper ladder 4 to the storage position P2 in order to have enough space at the traffic platform 3 to move or use equipment. For this purpose, the operator enters the amount before 5 of the scale 4 and moves it backwards by rotating the scale 4 around its first axis of articulation Xl. In this example, the force of the operator must oppose the force of the elastic means that constrain the ladder 4 in the use position P1. When the amount before 5 reaches the locking means 8, the scale 4 is locked in storage position P2. The ladder 4 makes it possible to prevent any fall in the manner of the guard rail 33 of the traffic platform 3 of the lower panel 1.
    [0023] To access the circulation platform 3 of the upper panel 1, the operator unlocks the ladder 4 which is driven by the elastic means in the use position P1. In this example, the panel 1 comprises a stop member for block the movement of the ladder 4 to the use position Pl. Similar to previously, the operator climbs the upper ladder 4 to access the traffic platform 3 of the upper branch 1. If a second operator moves the ladder 4 P2 storage position, the first operator can no longer open the hatch 32 of the upper tray 1 since the locking element 72 of the connecting means 7 prevents opening. To descend from the traffic platform 3 of the upper panel 1, the first operator must actuate the upper member 82, which allows the lower member 81 to unlock the front post 5 of the scale 4. By means of 4, the ladder 4 is automatically driven to the use position P1, which enables the second operator to open the hatch 32 and to descend from the traffic platform 3 of the upper board 1 safely. If the operator located under the traffic platform 3 30 wishes to unlock the ladder 4, it is sufficient to pull the handle 91 of the release means 9. Thanks to the invention, an operator can move up and down a banche 1 in a convenient and secure way. The difficulty of the operators is considerably reduced while maintaining optimal safety conditions.
