Detailed description of embodiments of the invention The invention proposes a scaffolding tower comprising a plurality of modules articulated one above the other, each module comprising a floor and 5 posts hinged to the floor, the posts being further hinged in their length. There scaffolding tower is capable of occupying a folded configuration in which each module is in the folded position and an unfolded configuration by unfolding vertical module by module, in which each module is in the unfolded position. The advantage is to realize a saving in time and cost when installing and dismantling the tower, while Favoriting 10 the safety of operators ensuring the installation of the tower.
By juxtaposing a plurality of scaffolding towers to each other in a unfolded configuration, in which each module is in the unfolded position, we gets a scaffolding. Scaffolding is an assembly of towers in the form of of column;
the towers can be put into unfolded configuration side by side or unfolded to 15 a few meters (for example in the street next to the place of use scaffolding) then juxtaposed with each other in an unfolded configuration. It is about even for the disassembly. The installation of the scaffolding by carrying out assembly in series of turns saves time - which is also the case for dismantling. By juxtaposition of towers, we hear that the towers and modules are side by side, aligned, neighbors, without 20 necessarily touch each other; a space may exist between the turns.
Also, we hear by juxtaposition that the towers and modules are neighboring, perpendicular between them (by example to follow a building angle) leaving an empty angle between the two.
Figure 1 shows an example of a scaffolding tower 10 and the scaffolding that results when juxtaposing a plurality of turns. Tower 25 of scaffolding and the resulting scaffolding during juxtaposition of a plurality of towers can be used as temporary construction for construction sites construction, as temporary construction for events (quick stands, private bleacher or bleacher support for a show, an event sports or attractions, etc.), as a temporary construction for observation or the socket 30 measurement, as a temporary support (antenna, sensors, lighting, hardware sound system for electrical cables or advertising), as temporary construction for spanning a road, as a workstation at height in industry, as temporary shelving or shelving for shops or warehouses, in as a fir tree or access tower or shoring tower, as a complement or in 35 association of one or more conventional scaffolding spans. By scaffolding conventional, we mean a scaffolding assembled by assembling tubes and fittings or with prefabricated elements (“frame” scaffolding, but above all also "multidirectional") in which the stages are progressively mounted on the length and the desired height of the scaffolding. In other words, a scaffold 40 conventional is able to be erected by successive assembly of elements individually (floors, posts, connection nodes, collars, bracing, stabilizers,

6 console or storage space, floor extensions, rubble guards, sleepers, chute evacuation, etc.).
The tower 10 comprises a plurality of modules 12 articulated one above of the others. Six modules 12 are shown by way of example in Figure 1; he is good 5 understood that the tower can include more or fewer modules 12, depending on the use which is made of it. Each module 12 includes a floor 14 and posts 16. The poles make it possible to support the upper modules. Floors are a surface allowing operators to move. Floors are, for example, a surface monobloc with a stiffening structure (such as a frame) or a surface supported by said structure.
10 The surface can be metal, wood or fiberglass. The surface can be fixed permanently to the structure or even removable from the structure. The surface can be of one holding or composed of sub-parts ¨ for example 20 to 35 cm wide. THE
modules contain components, such as posts or reinforcements floor, by example in metal or fiberglass. We can envisage that the floor of a module 15 is supported by the posts of said module; preferably (and as described later but in a non-limiting manner), a module comprises the floor 14 on which are placed and articulated the 16 ¨ posts by their lower end. Modules 12 can include four posts 16 in order to ensure the stability of the tower 10. But the invention is not limited to the presence of four posts 16 per module, as long as the stability of the 20 turn 10 is assured. Modules 12 are articulated to each other in the sense that the upper end of the posts 16 is connected and articulated to the floor 14 of module 12 superior. In addition, the posts 16 are articulated along their length. In other words, between their ends, the posts 16 comprise at least one articulation 18 their allowing you to bend. Preferably, the posts have a single joint 18, 25 allowing them to fold in half.
Figure 1 shows the tower 10 capable of occupying a folded configuration (on the LEFT
of Figure 1) in which each module 12 is in the folded position. THE
posts 16 are then folded in two at the level of the joint 18 in their length and folded against the lower floors (of the module) and upper floors (of the upper module) by the joint at 30 their ends. Figure 1 also shows the tower 10 capable of occupying a configuration unfolded (on the right of Figure 1) by vertical unfolding module by module, in which each module 12 is in the unfolded position. Joints 18 in the length of posts 16 and the joints on the floors allow the unfolding and the folding of modules 12 and therefore tower 10.
35 Tower 10 is therefore a one-piece system, unfoldable and foldable, for which the operator does not have to carry and assemble structural components.
The floors 14 and 16 posts are already in place when the tower is in configuration folded or unfolded. The tower saves time during its installation and its withdrawal. The advantage is that it is easier to prepare the tower before installing it because there is no no risk 40 for forgetting floors 14 or posts 16, as well as to remove it. In Besides, the height of the tower is prepared in advance, by superimposing as many modules 12 as required

7 to reach the desired height. Additionally, the tower in folded configuration maybe easily transported by truck - which greatly facilitates delivery of the tower.
Figure 2 shows an example of unfolding the modules 12. We see also the constitution of scaffolding 9 by juxtaposition of towers 10.
practical, the 5 modules 16 are unfolded one after the other, starting from the highest module of tower.
A lifting machine, such as a crane 20 (fixed or on a vehicle), makes it possible to unfold them modules 12 one after the other, by vertical traction of module 121 of top (from the above the top module 121). In Figure 2, the top module 121 supported by the crane is already in the unfolded position and the lower module 122 is in the process of being unfolding. Modules 10 more lower are still in a folded position. According to Figure 2, several rounds 10 with three modules 12 (as an example) are already in unfolded configuration. THE
modules unfold by gravity, which makes unfolding easier. As stated above, towers can be put in an unfolded configuration in a juxtaposed manner or the gap then juxtaposed once in unfolded configuration by movement by the machine lifting.
15 The Figure 3 shows another example of unfolding the modules 12. We also sees the constitution of scaffolding 9 by juxtaposition of towers 10.
Here, a machine lifting, such as a forklift 22, vertically deploys the modules according to the arrow 24, by lifting the last unfolded module vertically. In other words, the module 121 from the top is unfolded first, then the machine vertically lifts this module by the 20 below in order to unfold the lower module ¨ and so on by lifting the tower speak below the last unfolded module. Similarly to Figure 2, the modules 16 are unfolded one after the other, starting from the highest module of the tower.
The modules are unfold by gravity, which makes unfolding easier. A tower 10 comprising title example three modules 12 is already in unfolded configuration. A second turn 10 is 25 in progress deployment. As noted above, towers can be put into configuration unfolded in a juxtaposed manner or apart then juxtaposed once in configuration unfolded by movement by the lifting machine. The mode of realisation of Figure 3 is particularly applicable in the case where access from above not possible (in a building for example).
30 In order to allow vertical deployment of the modules 12, the tower 10 can include a vertical traction frame 13 of the tower 10, at the top of the module superior. THE
Figures 1 to 3 show the frame 13. The posts 16 are bolted into the frame angles 13. In the center, a lifting ring allows gripping preferably by a machine of lifting (whether in the deployment mode of Figure 2 or 3). The ring East positioned in the axis of the center of gravity of the tower, which allows lift the module the tallest and, where applicable, the tower as it remains vertical.
The floors 14 allow operators to move around in tower 10. The floors are with at least one passage hatch, allowing passage from one module 12 to another upper or lower module 12 of the tower. Floors 14 can have one or two passage hatches. Floors can also be without hatch passing through.

8 Figure 4 shows an example of production of a module 12 in position unfolded.
In particular, the posts 16, four in number for example, are shown more in details ¨ without the floor 14. The posts 16 have a joint 26 to their lower end, hingedly connecting the posts 16 to the floor 14 of the module 5 12. As shown with reference to Figure 1, the posts can also be articulate in their length, for example by the joint 18. In addition, the posts 16 include a joint 28 at their upper end, connecting in an articulated manner poles 16 on floor 14 of upper module 12. In Figure 4, module 12 (without floor) is in the unfolded position. In addition, the posts 16 of each module 12 are connected in pairs 10 by a torsion bar 30. This allows the synchronized unfolding of the posts 16 per pair, and prevent the posts from twisting. This improves the transition from a position to the other of module 12.
Figure 5 shows an example of production of a module 12 partially in folded or unfolded position. In this intermediate position (whether towards the position 15 unfolded or towards the folded position), the joint 18 allows you to fold posts 16 in two and joints 26 and 28 make it possible to bring two floors together superimposed one of the other, to achieve the configuration shown on the left of Figure 1.
Figure 6 shows an example of a module 12 in the folded position.
THE
posts 16 are folded in two thanks to the joint 18 and the joints 26 and 28 of 20 each post 16 are brought closer to each other. In this position, clutter of modules 12 is minimal, which allows easy transport and storage.
Figure 7 shows an example of realization of the relative position of the joints 18, 26, 28 of each post 16, in different positions of the posts 16.
The joint 18 in the length of each post 16 can be offset laterally by in relation to 25 other joints 26, 28 of the post, in the unfolded position of the module 12. On the part from the left of Figure 7, the post 16 is in a state corresponding to the position (completely) unfolded module 12; we see that the hinge pin represented by a hinge point 18 is not aligned with the hinge axis represented by a point of the upper 28 and lower 26 joints. This allows to ensure a 30 first security of tower 10 in the sense that, by this offset or not-alignment of three joints, the posts 16 are in a stable state, allowing a operator of complete the securing of the posts and modules as will be described by the more in detail. To move from a folded position to the unfolded position or vice versa modules, the joints 18, 26, 28 of the posts are actuated so as to pass through a state in 35 which the joint 18 is aligned with the two other joints.
26, 28; poles 16 are in an unstable state allowing them to be handled. On the part of right of the Figure 7, a movement towards the right of the joint 18 continues to cause folding from post 16 (towards the state of Figure 6); conversely, a movement towards left of the joint 18 continues to cause the post to unfold (and reach game state 40 left of Figure 7). Whether to fold or unfold a module, the posts 16 pass by the unstable state only by vertical lifting of the module. THE
uprising

9 vertical is operated by the lifting machine (which either lifts by traction all the tower be lift the last unfolded module from below). Performing an action of Lifting makes installation and dismantling safer.
Figures 8 to 11 show an example of carrying out the actuation of a 5 safety guardrail of modules 12. Each module 12 can include in besides the minus a safety guardrail 32 connected to a post 16 of each pair, the guardrail 32 safety lock blocking the articulation 18 in the length of the two posts 16 of the pair in the unfolded position of the module 12 and releasing the articulation 18 in the length of two posts 16 of the pair in the folded position of the module 12. The guardrail 32 allows

10 therefore a blocking of two posts 16 of the module in an unfolded state and a liberation of two posts 16 of the module in a folded state, which is sufficient to block or release the entire module 12. In addition, the guardrail 32 allows this change of state of synchronized manner of the two posts of each pair ¨ and therefore of the two pairs thanks to the torsion bar 30. The description of Figures 8-11 applies to both poles of the 15 pair ¨ in a synchronized and inverted manner.
Figure 8 shows the guardrail 32 sliding in a sleeve 34 of a post 16 ¨ and sliding in a similar sleeve 34 of the other post 16 of the pair.
The sleeve 34 is for example fixed to a stirrup 36 of the joint 18. According to the arrows 36, the parts upper and lower of the post 16 connected by the articulation 18 are in movement in 20 direction of the unfolded state of the post 16. The guardrail 32 slides in the sleeve 34 ¨
as well as in the sleeve 34 of the other post 16 of the pair. This is also visible on Figures 4 to 6 (in the movement in the opposite direction, towards the folded state of the posts 16).
In the unfolded position of the module 12, the two sleeves 34 are close of the free ends of the guardrail 32; in the folded position of module 12, the two 25 sleeves 34 approach each other towards the center of the guardrail 32.
According to Figure 8, the three joints 18, 26, 28 are aligned, as on the part right of figure 7 ¨ the post is in an unstable state. According to Figure 9, joint 18 is offset laterally relative to the other joints 26, 28 as on the part left of Figure 7¨ the post is in stable condition. From Figure 8, in the position 30 aligned with the joint 18 in the length of the posts with the other joints 26, 28 of the posts 16, the rotation of the guardrail 32 activates a cam follower 38 along from a cam 40 to a position of the guardrail 32 in which joint 18 in the length of the posts is positioned laterally offset by in relation to other articulations 26, 28 of the posts, this position of the guardrail 32 corresponding to 35 the unfolded position of the modules 12, shown in Figure 9.
In Figure 8, the cam follower 38 is not in the cam 40; on the figure 9, the cam follower 38 is engaged in cam 40 by the rotational movement of there guardrail 32 according to arrow 42. The cam follower 38 has a movement according to the arrow 44 along the cam 40, in a helical section of the cam 40.
40 Figures 10 and 11 show the final movement of the cam follower 38 towards the end of the cam 40, in order to block the guardrail in the unfolded position of the module 12.

WO 2023/2812

11 PCT/FR2022/051347 The cam 40 comprises a rectilinear section connecting the helical section to a section of blocking. According to Figure 10, the guardrail 32 is moved longitudinally by sort of move the cam follower 38 in the rectilinear section according to arrow 45.
Poles continue the movement according to arrows 46. According to Figure 11, the follower 38 cam 5 has reached the end of the rectilinear section of cam 40. A movement of rotation of the guardrail 32 according to arrow 48 makes it possible to engage the cam follower 38 in the section blocking the cam 40. The cam follower 38 allows the blocking of the guardrail 32 and therefore the blocking of the two posts 16 connected to the guardrail 32 in their state unfolded and stable.
Thus, the rotation of the guardrail 32 simultaneously activates the follower 38 of came the halfway along the cam 40 at the level of the post of each pair to which the guardrail 32 is connected.
The activation of the guardrail 32 by a single operator therefore makes it possible to block or of unlock the guardrail of two posts 16 and therefore of the entire module 12 of synchronized manner. This makes it possible to quickly ensure the modules are in unfolded position or conversely, to allow the modules 12 to be unlocked in order to fold them.
The whole thing is 15 operated in a secure manner with the lifting gear supporting the modules.
Figure 11 shows how to secure the guardrail 32 and the module 12 by position unfolded. The guardrail 32 is immobilized relative to the posts 16 to which she is connected by the cam follower 38 at the end of cam 40 ¨ this ensuring a first securing the guardrail 32 and the module 12. In addition, the guardrail 32 is immobilized 20 relative to the posts 16 to which it is connected by a pin 50 between the railing 32 and the sleeve 34 supporting the cam - this ensuring a second securing the guardrail 32 and module 12. Pin 50 extends through an orifice 52 through the sleeve 34 and the guardrail 32. The guardrail 32 held with the followers 38 cam at the bottom of cam 40 and with the pins 50 is immobilized relative to the sleeves 25 34 and so with respect to the posts 16 of the pair; the guardrail 32 prevents posts 16 to retreat. Thus, the two posts 16 to which the guardrail is connected and so all modules are held and secured in the unfolded position.
The installation is therefore simple and quick to install, while ensuring great safety.
The disassembly process is done in the opposite direction to the assembly process describe 30 above ¨ and is therefore just as easy while ensuring the safety of operators. As indicated, lifting or vertical traction by a lifting machine makes it possible to fold them modules, in particular, by passing through the unstable state of the posts, and this safe way.
The modules may include one or more safety guardrails ¨
preferably two safety guardrails. In Figures 4 and 5, a second guardrail 33, 35 lower than the guardrail 32 is provided. The guardrail 33 is connected to a post 16 of each pair by sliding in a sleeve similar to sleeve 34. A pin allows the guardrail 33 to be fixed in position relative to the posts.
Activation of the guardrail 32 (towards the unfolded or folded position of the module) also activates the guardrail 33.
In the unfolded position of the modules 12, a plurality of pins block the poles 40 16 in the unfolded state as well as the guardrail 32 in relation to the sleeves 34 and therefore in relation to the posts 16. More specifically, preferably four pins 50 block the joint 18 in the length of at least two posts 16 and the guardrail 32 by in relation to the two posts to which it is connected. According to Figure 11, a pin 50 is used to block the guardrail 32 to each of the posts 16 of the pair to which she is connected. Figure 12 shows an example of security implementation of 5 the articulation 18 of the posts not connected to the guardrail 32. A pin 50 blocks the joint 18 in the length of the posts 16. In the stable state of the posts 16 (in which the joint 18 is offset laterally relative to the joints 26 and 28), a pin blocks the stirrups 36 forming the joint 18 relative to each other to the other, in passing through an orifice 54. Thus, two pins 50 are used to poles 10 connected by the guardrail 32 and two pins 50 are used for the two other posts not connected by the guardrail 32 ¨ so four pins are enough to secure a module in the unfolded position. Other pins also allow you to block other components like the guardrail 33 in the unfolded position of the modules.
Figures 13 to 16 show an example of producing a ladder within of the 15 modules 12. The modules 12 can include a scale 56 with a joint 58 in its length (one joint per ladder upright), ladder 56 is mobile in rotation around a post 16 between a position of use of the ladder 56 in the unfolded position of the respective module 12, the scale 56 being in a plane orthogonal to axes of rotation of the joints of the posts and a position allowing the folding of 20 module 12. In the position allowing folding, the ladder is in the plan of the axes of rotation of the column joints. The scale therefore presents several benefits.
Ladder 56 can be folded and unfolded at the same time as the rest of the module.
It is not therefore no need to add ladder 56 at a later stage of assembly modules and the tower nor to manage the dismantling separately. The 56 scale allows also of 25 reinforce the security of the modules 12 in the sense that, in position of use, the scale prevents joints 18, 26, 28 from bending. The ladder blocks the change of state of posts which further increases the security of the modules and the tower.
In Figure 13, a lower module 12 is in the folded position and a module superior is in the unfolded position. Ladder 56 of the upper module is in position of use in 30 a plane orthogonal to the axes of the joints 18, 26, 28. Scale 56 maybe immobilized in the use position by a fixing 60 to the guardrail 32.
this allows to avoid a change of position of the scale 56 during its use.
In Figure 14, the scale 56 is changed position. Ladder 56 is in position authorizing the folding of the module 12. The scale 56 has undergone a rotation according to the arrow 62 35 around a post 16. The ladder is in the plane of the axes of the joints 18, 26, 28.
The axis of the articulation 58 of each upright of the ladder 56 is parallel to the axes of joints 18, 26, 28, which allows the folding of the ladder 56 at the same time time that the module ¨ which makes it easier to change the position of the module.
In Figure 15, after rotating the scale according to Figure 14, the module

12 can 40 be placed in the folded position. The posts 16 are bent according to the arrows 64, causing the movement of the joints 18 towards the inside of the module 12. The movement of the joints 26 and 28 allow the floor 14 of the upper module to lower according to arrow 66. The guardrail 32 slides relative to the posts 16 to which it is connected, allowing the module to be moved to the folded position. Scale 56 in position of the figure 14 folds at the same time as the rest of module 12.
5 The Figure 16 shows tower 10 in folded configuration in which each module 12 is in the folded position Ladder 56 was folded at the same time as the module respective.
In this configuration, the tower is compact and it is not necessary to separately transport components such as posts, floors, guardrails and ladders; the tower forms an easy-to-transport unit.
10 The Figure 17 shows an example of production of a safety guardrail 68 end. It is possible that each module 12 also includes a Or several end safety guardrails 68, mounted to rotate around a post 16.
For example, for modules intended to be at the end of the scaffolding 9, the end guardrail 68 makes the installation secure. The guardrail 68 maybe 15 rise to rotation around a post so that it can be opened if necessary. There rambade 68 is preferably the size of a lower half-post 16, so as to prevent the passage of a person but also to fold at the same time as a pair of poles 16 connected by the torsion bar 30. This makes it possible to make the guardrail 68 operational once module 12 has been unfolded without hindering the folding of module 12.
There 20 guardrail 68 is movable in rotation around a post 16 to be opened if necessary ;
in the closed position, the guardrail 68 can be secured by a pin introduced into a orifice 70 and a post 16 opposite the post 16 around which the guardrail 68 is mobile in rotation.
Optionally, the end safety guardrail 68 is removable. She can 25 be installed on the module if necessary or removed. This can be the cases for modules 12 which are not at the end of the scaffolding and for which it is not useful to have such a guardrail 68. For this, the guardrail 68 is tilted by its edge free upwards according to arrow 72 so that its edge connected to post 16 rotation tilts according to arrow 74. This makes it possible to separate an upper elbow 76 of the 30 guardrail 68 ensuring the rotation of the guardrail 68 around the post 16. The elbow 76 can be removed from the post 16. Then a lower elbow 78 of the guardrail 68 ensuring rotation of the guardrail 68 around the post 16 can in turn be removed from the post 16 in order to completely remove the guardrail 68.
Figures 18 and 19 show an example of connecting tabs between two modules 35 12. The Figure 18 shows tower 10 in folded configuration with two modules 12 visible, in the folded position. The tower is ready for transport. Tower 10 has connecting tabs 80 between two modules in the folded position. The connecting tabs guarantee that the modules cannot unfold during transport or even transshipment. Of preferably, a connecting tab 80 is provided at each of the four corners of the modules 12. A
organ of 40 fixing 82 allows you to fix a connecting tab between two modules and prevent the unfolding. The connecting members 80 are for example screws with a nut butterfly

13 as a nut so as to easily attach or remove the connecting tabs 80.
The legs of fixing 80 can be movable in rotation relative to the modules, facilitating their use. The rotational movement may be around the fastener 82.
Figure 19 shows tower 10 in unfolded configuration with two modules 12 5 visible, in unfolded position. The tower 10 may include the legs of connection 80 between two neighboring 12 modules in the unfolded position. In other words, when the towers are positioned side by side, it is preferable to fix the towers together;
the connecting tabs 80 can be used to fix together two 12 modules adjacent to two towers different. A
rotational movement of the legs allows the modules to be fixed together.
10 The fixing lugs 80 may comprise at one of their ends a hole of passage of the fixing members 82. Whether the fixing member 82 is tight or loosened, the fixing tabs 80 remain attached to the respective module, which avoids to misplace a fixing bracket 80. For attachment to another module, the mounting brackets attachment 80 can understand another fastening member passage at their other end, such as that is 15 visible in Figure 18. The fixing lugs 80 are then fixed by their two ends to the modules. The fixing lugs 80 can also include in a manner optional an indentation 81, in the shape of a comb, making it possible to fix the tabs of fixing 80 to another module 12 positioned at a distance other than the distance between the two passes of a leg fixing member. In Figure 19, we see that the gap between both 20 modules 12 neighbors is less important than the length of a leg of fixing 80. It is therefore possible to fix the modules together by a fixing member 82 to an extremity of a tab 80 and by another member for fixing a neighboring module in positioning the fixing member 80 in an indentation 81 of the fixing lug 80.
The legs of fixings 80 thus make it possible to fix two modules 12 between them, while adapting to 25 the space between the two modules.
Figure 20 shows an example of producing telescopic extension rods.
There tower 10 may further comprise rods 84 mobile telescopic extensions between a retracted position in the floor 14 of the respective module and a position taken from floor 14. Arrow 85 shows the movement of the rods 84 towards the position extracted. A
30 floor extension 86 can then be fixed on the rods 86 in extracted position. At least two rods 84 are provided per module, in order to ensure the stability of the extensions 86; of preferably, three rods 84 are provided in order to avoid buckling of the extensions 86 under the weight of a person. The telescopic nature of the rods 84 makes it possible to use these stems and extension cords only if necessary, if a space exists between the tower and a building against which 35 the tower is unfolded. This also makes it possible to take into account standards in the case applicable. THE
extensions 86 are for example placed on the floors during preparation of the tower before installation; it is then sufficient to position the extensions 86 on the rods 84 according to arrow 88. The extensions 86 can be secured to the rods 84 by a fixation such as nuts, butterfly, pins or clips. Extensions 86 can also be fixed 40 to a module component when preparing the front tower installation or disassembly to avoid a fall when unfolding or folding the modules. He is Also

14 possible that the extensions 86 are placed on the rods 84 during folding or unfolding of modules.
As can be seen in Figure 2, tower 10 can also include cables 90 removable or permanent triangulation on the modules. The 90 cables of 5 triangulation makes it possible to avoid lateral folding of the modules, and therefore of the tower. THE
cables 90 are for example easily screwed by butterfly nuts between two floors.
They are removable or permanent depending on whether these relaxed cables 90 hinder or no handling the tower in the folded position.
Independently of the jacks 92 with a flat base, the scaffolding 9 can include a 10 or more rounds 12 as a complement or in combination with a or many conventional scaffolding spans. Conventional scaffolding means A
scaffolding assembled by assembly of tubes and fittings or with elements prefabricated (mainly scaffolding, "multidirectional", "frame", or even more rarely rolling or suspended / console scaffolding) in which the floors are

15 gradually mounted along the length and height of the scaffolding desired. In in other words, a conventional scaffold is a scaffold capable of being drawn up by successive assembly of unitary elements. A span of scaffolding conventional is capable of being erected by successive assembly of unitary elements (floors, poles, connection nodes, collars, bracing, stabilizers, console or space of 20 storage, floor extensions, rubble guards, sleepers, chute evacuation, etc.). In Indeed, construction sites can have specific features such as a sidewalk, my door, a slope of the land etc. which complicate and delay the installation of a scaffolding because the specificity must be overcome while authorizing pedestrian, road, etc. For this reason, and as can be seen in Figure 24, the scaffolding 9 can understand a 25 part in the form of conventional scaffolding 120 and another part in as long as turn having the characteristics described elsewhere. In other words, scaffolding 9 may comprise at least one tower 10 comprising a plurality of modules 12 articulated one above the other, the tower being able to occupy different configurations, in association with one or more conventional scaffolding spans 120 30 (potentially by being secured together), that is to say, in association with one or several scaffolding spans capable of being erected by successive assembly of elements unitary (structural elements or equipment). The synergy between the rounds 10 and conventional scaffolding spans allow for rapid scaffolding has install or disassemble which adapts to different construction site configurations.
Such 35 scaffolding ensures cost savings in the installation and dismantling of the scaffolding.
Also, the scaffolding ensures the safety of operators and people foreign to construction site.
By way of example, with respect to the tower(s) 10, the scaffolding spans conventional can be below (for example, as a base type passage 40 pedestrian or to compensate for a difference in height), above (for example as bottom protection slope, such as half-frame or half-level to adjust the height of scaffolding, as a roof access walkway, as a shoring tower or as formwork support), on the sides or in juxtaposition (for example a floor or a multi-directional column or tubes and fittings, such as a crosspiece, a enjambment, a beam or walkway), at the rear of the scaffolding (for example, like row additional scaffolding to facilitate circulation, for storage or like access or lifting tree), at the front of the scaffolding (in the case of rows multiple, as a walkway for access to the roof or to follow an overhang, for example on the shipbuilding site or under stands), or even as an interface between two 10 towers superimposed vertically.
10 According to Figure 16, the lowest module 12 of the tower 10 can include jacks 92 with flat or flanged base. The jacks 92 are for example parts telescopic ¨ by for example by screwing! unscrewing ¨ allowing the flatness of the tower to be adjusted depending on the soil.
The 92 cylinders with a flat base allow the lowest module to be placed on the ground. The cylinders 92 with flanges allow the lowest module, and therefore the tower, to be fixed on a structure lower. For example, it is possible to mount the tower on scaffolding lower allowing the passage of people along a sidewalk, to compensate for a elevation of terrain or to allow the tower to overcome a door. We can thus combine or associate one or more towers 10 and possibly the resulting scaffolding with a conventional scaffolding (as described previously). For example, it is possible to mount the tower by covering it at its top with protection at the bottom of the slope scaffolding suitable for roofing work, or even a half-frame allowing to position the workstation precisely at the desired height (under a gutter or at the level of a parapet for example), or even a footbridge leading to the roof, or still support allowing the resumption of a heavy load during a use as 25 round shoring or as formwork support. For example, it is possible to ride the tower in juxtaposition of a single level or an entire column made in scaffolding multidirectional or in tube and fittings, allowing adaptation to one or several facade outgrowths (balconies, cornices, decorative elements, etc.) - this column or this floor alone can take the form sometimes of a classic floor, sometimes of a beam 30 or crossbar allowing the crossing of facade obstacles or ground obstacles occasionally prohibiting the installation of a column 10 (or simply to connect a number the smallest possible number of columns 10 of the scaffolding 9, in the case by example of roofing work, in order to save time). For example, it is possible to climb the tower by adding one or more rows of scaffolding at the rear allowing a better circulation, whether it has a footprint or whether it is used in console of tower 10/scaffolding 9, or even an access tree allowing the workers to move around better on floors without hindering themselves, a lifting tree allowing to transport materials at the right height, or as storage space of materials at the height of use (tiles, coatings, etc.). For example, it is possible to 40 rise the tower by adding a floor at the front (console, gateway or not), or one or more scaffolding columns in order to adapt to a recess of building

16 or to follow a slope, for example on construction sites naval or under stands to best fit the vessel or support). By example, it is possible to mount two towers 10 superimposed vertically by separating them of a interface in the form of a half-frame or half-height scaffolding for reach more 5 precisely desired working heights impossible to adjust with only the use of jacks 92 with a flat base.
Figure 21 shows an example of a junction 94 between two modules 12 neighbors. The junctions 94 are positioned between two neighboring modules 12 separated by an area. The junctions allow you to connect two modules of two towers different then 10 that a void exists and that this void cannot be filled by a tower or a module. THE
junctions 94 then serve as bridges or footbridges. The modules can be in the same aligned but separated by a space. Junction 94 then allows extend both neighboring modules towards each other. Modules can be perpendicular one with the other (for example to follow a building corner) leaving an empty corner between the 15 two. The junction 94 then makes it possible to fill the angle between the two neighboring modules.
The junction 94 (between two modules separated by a space or an angle) includes a floor 14 and a safety barrier 96. The barrier is hinged to the floor, which allows it to be folded to reduce its bulk when transporting junctions 94. The barrier 96 includes a locking member 98 making it possible to lock the barrier 20 with the guardrail 32 of the neighboring module to ensure the safety of operators. We can also consider two safety barriers 96 in the case of a junction 94 corner.
The junction 94 (between two modules separated by a space or an angle) can be besides include a lifting ring 102 retractable in the floor 14 to the right of the top of the safety barrier 96 positioned between 50 and 70 relative to the floor of 25 preferably around 60 ¨ and a double lifting ring 104 on the top of the barrier. There junction is able to remain substantially horizontal by lifting by a cable 100 fixed between the two rings 102, 104 (maintaining the inclined barrier) and by a cable 106 fixed at ring 104.
One or the other of the floor and the neighboring module 12 includes plates in protrusion 30 supporting an axis 108 penetrating into a respective orifice on the other of the floor or neighboring module 12. According to Figure 21, junction 94 (between two modules separated by a space or an angle) may include plates projecting from the floor 14 supporting the axis 108 penetrating into the respective orifice of a neighboring module. This allows to fix in a way secure the junction with the neighboring module. Additionally, a pin can be scheduled for 35 block the withdrawal of the axis 108 from the orifice. This allows to secure the hanging of the junctions 94 to modules 12.
Figure 22 shows an example of a junction 94 between two modules neighbors. The junctions 94 are positioned between two neighboring modules 12 separated by a corner. A view from below is shown. A junction 94 intended for connect two 40 neighboring modules 12 separated by an angle can include a floor 14 and beams 110 in a cross on which the floor 14 rests. This ensures the stability of junction 94

17 trodden by an operator.
Junction 94 (between two modules separated by a space or an angle) can Also include extension rods 84 as described above to support An extension 86.
5 The Figure 23 shows an example of a module 12 with a staircase 112.
The staircase 112 allows you to move easily between the modules, within the round scaffolding; for example, the staircase allows operators to move more easily while carrying loads with both hands, which is not possible by the ladder 56. The staircase 112 can be brought back into an unfolded module ¨ or removed before folding of 10 module.
Preferably, the staircase 112 is articulated to the module 12 and is put into place during the unfolding of the module or follows the movement of the module when folding. For example, the staircase 112 is articulated to the module by its upper end and is suitable to slide on the floor of module 12 by its lower end. So, during the folding or unfolding of the module, the staircase 112 follows the change in position of the module.
In position 15 folded from module, the lower end of the staircase 112 slides and slides out of module. In the unfolded position of the module, the lower end of the staircase 112 slide and slides towards the inside of the module. Once the module is unfolded and the staircase 112 in place, the lower end of the staircase 112 is locked, for example by pin.
The upper end of the staircase 112 is for example articulated by the two amounts 20 to posts 16 or the torsion bar 30. In addition, the staircase 112 allows to reach a upper module (or to descend from it) through an empty passage in the floor 14 ¨ which maybe closed by a trapdoor, or not.
The invention is therefore a modular scaffolding solution, foldable and simplified assembly. We obtain a saving of time for the installation because in general, a 25 such installation often blocks a street. The scaffolding is in one piece, in modules foldable and unfoldable over for example at least 6 m, preferably at least 10 mr.
The scaffolding can reach 20 m high, or even 30 meters. The scaffolding is constituted juxtaposable towers; the scaffolding is devoid of stability arms by ground rest extending beyond the floor space of the modules, which allows juxtapose the towers 30 in series (but may include some if a single tower 10 is used). THE
deployment of a tower is carried out without human intervention, but in a mechanized way, of preferably by lifting equipment; it helps reduce accidents. There security by several means described above is done by an operator, in complete security thanks to the lifting machine. In addition, the tower may include a number of components (such as that 35 posts, floors, safety railings, ladders, etc. if applicable) already in place In the folded position of the tower and which find themselves in place in the position unfolded ¨ and Conversely. A 10 m tower can weigh between 1000 to 2000 kg ¨ as for example, this which is not possible for a man to handle with his bare hand (but by a machine of lifting). The modules are, for example, more than 2 meters wide, but preference 40 under 2.4 meters wide to accommodate crosswise on a 2.5 meter truck wide. The junctions can measure for example between 2 and 4 meters of long.

18 The towers are of a height suitable for the use mentioned above, and are suitable for being juxtaposed to cover a large length of use. THE
assembly done in columns and lateral juxtapositions and not in line like traditionally.
The unfoldable and foldable nature by articulation allows a level of compactness folded 5 very important.
Towers 10 have the ability to be pre-assembled and folded assemblies articulation, which makes them as compact as possible. They are unfolded (and folded) by a lifting machine, which lifts the entire tower (from the top or from the below the last module unfolded). All components are already assembled, no operation 10 manual in floor is necessary for installation and dismantling ¨
uniquely the activation of the safety devices described. The lifting machine is for example a crane, a forklift, truck crane, manuscopic, etc. The fact that the process of unfolding or folding described above of the modules during installation or disassembly is possible only by vertical lifting of the modules by the machine lifting for 15 each module level, assumes that the lifting means is present.
The lifting machine secures both installation and dismantling (and therefore the descent of the modules and turns). We thus prevents folding from being made by a sudden fall from a level without be hung and secured from above by the lifting device. The described process steps of folding and unfolding of modules and towers, as well as juxtaposition of towers, ensure a gain 20 time and operator safety.
