Abstract
The invention proposes a scaffolding tower (10) comprising a plurality of modules (12) articulated one above another, each module (12) comprising a floor (14) and posts (16) articulated with the floor (14), the posts (16) additionally being articulated along their length, the scaffolding tower (10) being able to adopt a folded configuration, in which each module (12) is in a folded position, and an unfolded configuration, obtained by vertical unfolding module by module, in which each module (12) is in an unfolded position. The invention also relates to a scaffold. The invention allows time to be saved and permits enhanced safety.
Claims27
A scaffolding tower (10) comprising a plurality of modules (12) articulated one above another, each module (12) comprising
- a floor (14), and
- posts (16) articulated to the floor (14), the posts (16) additionally being articulated along their length,
- the scaffolding tower (10) is able to adopt a folded configuration in which each module (12) is in the folded position and an unfolded configuration, obtained by vertical unfolding module by module, in which each module (12) is in the unfolded position.
The scaffolding tower (10) according to one of the preceding claims, wherein a module (12) is able to unfold by vertically pulling the module from the top or by vertically lifting the last unfolded module.
The scaffolding tower (10) according to one of the preceding claims, wherein each post (16) of a module (12) comprises a hinge (26) to the floor (14) of said module (12) and a hinge (28) to the floor of the upper module, each post (16) further comprising an articulation (18) along the length which is laterally offset relative to the other articulations of the post, in the unfolded position of the module.
The scaffolding tower (10) according to the preceding claim, wherein the switch to the folded or unfolded position of a module is possible only by vertically lifting the module.
The scaffolding tower (10) according to the preceding claim, wherein,
- between the folded position of the modules (12) and the unfolded position of the modules (12), the articulation (18) along the length of the posts is aligned with the other articulations (26, 28) of the posts to the floors and
- in the unfolded position of the modules (12), the articulation (18) along the length of the posts (16) is offset laterally relative to the other articulations (26, 28) of the posts to the floors.
The scaffolding tower (10) according to one of the preceding claims, wherein the posts of each module are connected in pairs by a torsion bar (30), each module (12) further comprises at least one safety railing (32) connected to a post (16) of each pair, the safety railing (32) locking the articulation (18) along the length of the two posts (16) of the pair in the unfolded position of the module (12) and releasing the articulation (18) along the length of the two posts (16) of the pair in the folded position of the module (12).
The scaffolding tower (10) according to the preceding claim, wherein the rotation of the railing (32) simultaneously activates a cam follower (38) along a cam (40) at the post of each pair to which the railing is connected.
The scaffolding tower (10) according to one of the two preceding claims, wherein the railing (32) is immobilized relative to the posts (16) to which it is connected by the cam follower (38) at the end of the cam (40) and by a pin (50) between the railing (32) and a sleeve (34) supporting the cam (40), the two posts to which the railing is connected and the modules are held in the unfolded position.
The scaffolding tower (10) according to one of the preceding claims, wherein the modules (12) comprise a ladder (56) with an articulation (58) along its length, the ladder is rotatable around a post between
- a position of use of the ladder (56) in the unfolded position of the respective module (12), the ladder being in a plane orthogonal to the axes of the articulations of the posts
- and a position authorizing the folding of the module (12).
The scaffolding tower (10) according to one of the preceding claims, each module further comprising at least one end safety railing (68), rotatably mounted around a post (16) and optionally removable.
The scaffolding tower (10) according to one of the preceding claims, further comprising a vertical pulling frame (13) of the tower at the top of the upper module.
The scaffolding tower (10) according to one of the preceding claims, wherein the floors (14) are with at least one passage hatch.
The scaffolding tower (10) according to one of the preceding claims, further comprising connecting tabs (80) between two modules (12) in the folded position or between two neighboring modules in the unfolded position of two juxtaposed towers, the connecting tabs (80) optionally comprising an indentation (81) matching the gap between the modules.
The scaffolding tower (10) according to one of the preceding claims, further comprising telescopic extenders (84) movable between a position retracted in the floor (14) and a position extracted from the floor, a floor extension (86) being attached to the extenders (84) in the extracted position.
The scaffolding tower (10) according to one of the preceding claims, further comprising removable or permanent triangulation cables (90) on the modules.
The scaffolding tower (10) according to one of the preceding claims, wherein the lowest module comprises flat-base or flanged jacks (92).
The scaffolding tower (10) according to one of the preceding claims, wherein the module (12) comprises a stairway (112) articulated to the module by one end.
A use of the scaffolding tower (10) according to one of the preceding claims, as a temporary structure for construction sites, as a temporary structure for events such as rapid-build stands, private bleachers, or bleacher supports for a show, a sporting event or attraction, as a temporary structure for observation or measurement-taking, as a temporary support such as for an antenna, sensors, lighting, sound equipment, electrical cables or advertising, as a temporary structure for spanning a roadway, as a station for working at height in industry, as a shelf or a temporary shelving for shops or warehouses, as a main scaffolding tower or access tower or shoring tower, as a supplement or in combination with one or more conventional scaffolding spans.
The scaffold (9) according to the preceding claim, wherein
- the junctions (94) comprise
- a lifting ring (102) retractable into the floor in line with the top of the safety barrier positioned between 50 and 70° relative to the floor (14), and
- a double lifting ring (104) on the top of the barrier,
- the junctions (94) being able to remain substantially horizontal by lifting by one or more cables moored to the retractable lifting ring (102) and to the double lifting ring (104),
