    [0001] BACKGROUND OF THE INVENTION The invention relates to the field of construction work. When building multi-storey buildings, corbelled platforms are usually used, attached to the outside of the building wall. These corbelled platforms allow for work from the outside of the wall, including the construction of the upper levels of the building. These cantilevered platforms are usually attached to the outside of the wall by means of support and fasteners. Traditionally, the construction of a wall consists of making sections of walls that are arranged one above the other. To do this, the corbelled platforms are successively attached to the lower pan of the wall wall during the manufacture of the upper pan, then are separated from the lower pan to be fixed to the upper pan, and so on. It is therefore understandable that the manufacture of a wall wall requires many operations of joining and disconnecting the corbelled platform. Frequently, buildings include balconies that protrude perpendicular to the wall. Traditionally, there are several methods for making such balconies. According to one method, a shoring tower is used which is placed on a lower balcony previously manufactured. To carry out this operation, first remove the working platform, take the shoring tower and position it on the lower balcony.
    [0002] These successive assembly and dismantling operations consume resources and make construction operations slow. OBJECT AND SUMMARY OF THE INVENTION An object of the present invention is to remedy the above-mentioned drawbacks. The invention achieves its object by the fact that it relates to a corbel work platform convertible into a shoring tower comprising: a frame provided with a floor, the frame having a front portion and a rear portion; a pair of trusses intended to bear against a wall, the trusses being pivotally mounted relative to the frame about a first axis of rotation, said trusses having a working position in which they extend perpendicular to the floor, and a row position in which the trusses extend substantially parallel to the floor, below said floor; the corbelled working platform further comprising: a retractable support device fixed under the frame and comprising a plurality of pivoting feet, the legs having an extended position in which said feet extend perpendicularly to the floor so as to be able to bear against a substantially horizontal surface located under the corbelled work platform, and a retracted position in which the feet extend substantially parallel to the floor, in which, in a first configuration, the platform is attached to a wall wall, the trusses being in the working position while the feet of the support device are in the retracted position, in which, in a second configuration, the support device, in its deployed configuration, forms a shoring tower, the feet then being configured to come into support against a substantially horizontal surface and located under the This is a corbelled work structure, the floor forming a formwork for a balcony.
    [0003] This substantially horizontal surface located under the corbelled working platform may be a lower balcony previously made, or the floor of another work platform cantilever below. It is therefore understood that the corbelled working platform according to the invention is convertible into a shoring tower. It is understood that in the configuration "shoring tower", the feet of the support device bear against the horizontal surface of the lower balcony or floor of the other work platform cantilever. Also, thanks to the invention, the same tool is both the corbelled work platform and the shoring tower. An interest is to reduce the number of tools present on the site, which allows to reduce the costs of materials. This also allows operators to become more efficient when the corbelled work platform can be converted very quickly into a shoring tower, and vice versa. This further reduces the time of use of the cranes, which further reduces the cost of manufacturing balconies. Advantageously, the legs are in the retracted position when the trusses are in the working position, and the trusses are in the stowed position when the feet are in the deployed position.
    [0004] It will be understood that when it is desired to use the corbelled work platform in a conventional manner, by fixing the latter to the wall wall, the trusses are in the working position, while the feet are in the retracted position under the floor. To convert the working platform into a cantilever in a shoring tower, the feet of the support device are deployed to bring them into the deployed position. Preferably, the trusses are then brought to the stowed position. They then extend parallel to the floor, below the latter. Another advantage of the invention is to provide a corbel work platform convertible into a shoring tower which has a compact closed position. In this closed position, the farms are in a stowed position while the feet are in the retracted position. Also, the convertible cantilever working platform according to the invention is particularly convenient to store and transport.
    [0005] According to one variant, the retractable support device comprises a first support element and a second support element, each support element comprising a crossmember which extends along the width of the chassis between its front part and its rear part, when said device bracket is mounted to the chassis.
    [0006] According to a variant, the crosspiece extends parallel to the trusses when the latter are in their stored position. According to a variant, in the first configuration, the platform is fixable to a vertical wall wall by means of a fastener.
    [0007] According to one variant, the floor, which defines a horizontal surface, is bordered at the rear of the chassis by a safety barrier. According to one variant, other lateral barriers extend along the longitudinal edges of the chassis or the floor. According to a variant, the pivot connection between each of the trusses and the frame is disposed at one of the longitudinal ends of said truss. According to a variant, the trusses are locked in the working position by means of uprights, each upright consisting of two bars articulated relative to one another about an axis of rotation. Each upright is also pivotally mounted relative to one of the trusses along an axis of rotation and relative to the frame about an axis of rotation. For locking in the working position, the platform further comprises a locking arm which extends between the axis of rotation and closes substantially perpendicular to said farm.
    [0008] According to a preferred embodiment of the invention, the feet are pivotally mounted along axes of rotation parallel to the first pivot axis. Also, the legs and trestles rotate in planes parallel to each other so as to avoid any risk of collision between the feet, which facilitates the handling of the platform according to the invention. Preferably, the support device is fixed to the frame by means of a fastener. This fixing member is preferably mounted on the support device. The presence of this fastener allows in particular the mounting of the support device on different models of corbelled working platform which are initially devoid of such a support device. In a variant, the support device is welded to the frame. According to a preferred embodiment of the invention, the retractable support device comprises at least two support elements, each support element comprising: a cross member extending along the width of the chassis, between its front part and its rear part a first foot pivotally mounted relative to the cross member according to a first axis of rotation parallel to the first pivot axis; a second foot pivotally mounted relative to the cross member according to a second axis of rotation parallel to the first pivot axis. It is therefore understood that the crosspiece extends perpendicular to the wall wall to which the corbel platform is fixed. In other words, the crosspiece extends parallel to the trusses when the latter are in their stored position. Preferably, in the retracted position, the first and second feet extend substantially parallel to the cross while being arranged one above the other. An interest is to provide a support device that is compact when in the retracted position. Alternatively, in the retracted position, the feet are positioned next to each other substantially at the same level. Advantageously, the crosspiece has a first end and a second end opposite the first end, and the first foot is fixed to the cross member by means of a connecting element which is slidably mounted along the cross-member in order to be able to adjust the cross-section. wheelbase of the retractable support device according to the width of the chassis.
    [0009] Also, the invention makes it possible to adapt the wheelbase of the support device to the width (considered in a direction perpendicular to the wall) of the lower horizontal surface. For the safety of the platform, the support element preferably comprises a locking member to lock the position of the connecting element relative to the crosspiece. According to a preferred embodiment, but not exclusively, the support elements are located on either side of the two farms, near the longitudinal ends of the floor. In a variant, the support elements are located along the end edges of the frame, which may be set back from the end edges of the floor.
    [0010] Advantageously, in the closed position of the platform, that is to say when the trusses are in the stowed position and the feet in the retracted position, the trusses extend parallel between the two support elements.
    [0011] According to a preferred embodiment, the feet are telescopic, which allows to adjust the length of the feet. An interest is to be able to adapt the length of the feet to the distance separating the platform from the lower surface on which the feet are supported. According to a variant, the support device further comprises inserted rods which connect two feet together when they are in the deployed position. An interest is to improve the rigidity of the support device in the deployed position. Preferably, the support device comprises four feet. According to another variant, the support device comprises two rear feet, the front feet being constituted by the trusses in working position. In this variant, the lower ends of the trusses also bear against the lower horizontal surface. The invention further relates to the use of a corbelled working platform according to the invention for producing a balcony formwork. In this case, the formwork is made on the floor of the platform. According to one aspect, there is provided a retractable support device for a cantilever working platform according to the invention, said retractable support device comprising at least two supporting elements, each support element comprising: a cross member extending according to the width of the frame when the support device is fixed to the frame, a first foot pivotally mounted relative to the cross member according to a first axis of rotation parallel to the first pivot axis; A second foot pivotally mounted relative to the cross member along a second axis of rotation parallel to the first pivot axis. Advantageously, said support device further comprises a fastener for attachment to the frame of the corbelled working platform. According to a preferred embodiment, but not exclusively, the fixing member comprises two lugs facing each other, each lug being disposed at one of the longitudinal ends of the crossmember. The lugs are shaped to fit into holes in the frame. Such a fastener makes it possible to mount the support device on frames of different dimensions.

    [0013] DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows a convertible cantilever work platform 10 according to the present invention. This platform 10 is fixed to a vertical wall wall M by means of a fastener A, known elsewhere. The convertible cantilever work platform 10, hereinafter called platform, comprises a frame 12 provided with a floor 14, the frame having a front portion 12a and a rear portion 12b. As can be understood from FIG. 1, the frame 12 has a width I, this width extending in a direction perpendicular to the wall wall M. Said otherwise, the width I extends between the front part 12a and the rear portion 12b of the frame. With the help of Figure 1, it is conceivable that the front portion 12a of the frame is the one that is closest to the wall wall, while the rear portion 12b is located at a distance from the wall wall M.
    [0014] The floor 14, which defines a horizontal surface, is bordered at the rear of the chassis by a safety barrier 16. Other lateral barriers, not shown here, extend along the longitudinal edges of the frame or the floor. Conventionally, the platform 10 includes a pair of trusses 18 which are intended to bear against the wall wall M. The trusses 18 are pivotally mounted relative to the frame 12 about a first axis of rotation A. As it is note with the aid of Figure 1, the pivot connection between each of the trusses 18 and the frame is disposed at one of the longitudinal ends of said farm 18.
    [0015] The trusses have a working position, illustrated in Figure 1, in which they extend substantially perpendicular to the floor. In this working position, the trusses extend substantially parallel to the wall wall M.
    [0016] In this example, the trusses 18 are locked in working position by means of uprights 20, each upright 20 consisting of two bars 20a, 20b hinged relative to one another about an axis of rotation B Each upright 20 is also pivotally mounted relative to one of the trusses 18 along an axis of rotation C and relative to the frame about an axis of rotation D. For locking in the working position, the platform comprises in addition to a locking arm 22 which extends between the axis of rotation B and the firm 18 substantially perpendicular to said farm 18. The trusses 18 further comprise a stowed position in which they extend substantially parallel to the floor, below of said floor 14.
    [0017] According to the invention, the convertible cantilever working platform 10 further comprises a retractable support device 40 which, in this example, is fixed to the chassis, below the latter by means of fasteners 42.
    [0018] The retractable support device 40 comprises a plurality of pivoting feet 44, 46, 48, 50. As can be seen in Figures 2, 3, 5, 6, 7, the retractable support device has an extended position in which the feet 44, 46, 48, 50 are themselves deployed so as to extend perpendicular to the floor 14. In its deployed configuration, the support device forms a shoring tower, the feet then being configured to bear against a S surface substantially horizontal and located under the corbelled work platform 10. In the example of Figure 2, the surface S is the upper surface of a balcony B1 integral with the wall wall M, said balcony B1 having been previously manufactured . In the example of FIG. 3, the surface S is constituted by the floor 14 'of another cantilever work platform 10' which is fixed to the wall wall M below the corbelled work platform 10. As it is understood by means of Figures 2 and 3, the trusses 18 are in the stowed position when the feet 44, 46, 48, 50 are in the deployed position. With the help of Figures 2, 3, 5 and 6, it is found that the feet 44, 46, 48, 50 are telescopic so as to adjust the height H of the floor relative to the surface S. Referring now to Figures 4 to 7, we will describe in more detail the support device according to the invention. As can be seen in particular in FIG. 4, the feet are pivotally mounted along axes of rotation X1, X2, X3, X4 which are parallel to the first pivot axis A. This is clearly visible in FIG. Figures 1 and 4, it is understood that the retractable support device 40 comprises a retracted position in which the feet 44 46, 48, 50 extend substantially parallel to the floor, below said floor.
    [0019] It is also understood that the feet are in the retracted position when the trusses are in working position. Referring to FIG. 7, it can be seen that the retractable support device 40 comprises a first support element 60 and a second support element 70. Each support element comprises a cross-member 62, 72 which extends along the width of the frame 12 between its front portion 12a and its rear portion 12b, when said support device is mounted to the frame. Each crossmember is arranged to extend substantially perpendicular to the wall wall M.
    [0020] With the help of Figures 4 and 5, we will describe the first support member 60, it being specified that the second support member 70 is substantially identical. The first support member 60 includes the first leg 44 which is pivotally mounted relative to the cross member 62 along the first axis of rotation XI parallel to the first pivot axis A. The first support member 60 further comprises the second leg 46 which is pivotally mounted relative to the crossmember 62 along a second axis of rotation X2 parallel to the first pivot axis A. As seen in FIG. 4, in the retracted position, the first and second legs 44, 46 of the first element of FIG. support 60 extend substantially parallel to the cross member 62 while being arranged one above the other. Furthermore, the cross member 62 has a first end 62a and a second end 62b opposite the first end 62a. These are the longitudinal ends of the crossmember 62. The first leg 44 is fixed to the crossmember 62 by means of a connecting element 64 which is slidably mounted along the crossmember 62 in order to be able to adjust the wheelbase P retractable support device according to the width of the frame. To adjust the wheelbase, the crossmember 62 is provided with orifices 66 spaced apart from each other which define positions for the connecting member with respect to the crossmember. In order to effect the locking of the connecting element with respect to the cross-member 62, the support element 60 comprises a locking member, in this case a pin 68, which cooperates with both the connecting element 64 and the orifices 66 formed in the cross member 62.
    [0021] Moreover, it can be seen that the fixing members 42, in this case provided with lugs arranged facing each other, are arranged at each of the longitudinal ends 62a, 62b of the crossmember 62. Referring to FIG. which illustrates the platform 10 in a configuration in which the support device is in the deployed position, in rear view, it is found that the support elements 60, 70 are located on either side of the two farms 18, near the ends longitudinal 141, 142 of the floor 14. It is understood that when the trusses 18 are in the stowed position and the legs in the retracted position, the trusses extend parallel between the two support elements. Finally, Figure 2 illustrates an example of the use of the corbelled work platform, converted into a shoring tower, to produce a balcony formwork C.
