Definitions
- the present invention relates to a platform support device for the elevation of loads or persons along a structure, particularly for the execution of work applied to said structure, this device comprising, in combination with a platform, lifting elements of the winch type platform to adjust at will the elevation level of the platform, modular elements assemblable forming the mast to reach a desired height, the establishment of each mast element s' carrying out from the load platform reliable to the masts on the one hand by the winch type lifting elements disconnectable at will said masts, on the other hand by means of temporary immobilization of the platform relative to a modular element of each mast to allow, in the immobilized state of the platform, the addition or the deletion at the top of the masts of at least one modular element as a function of the height of levation the desired platform.
- the work along high-rise building facades is mostly done from so-called suspended scaffolds.
- Such scaffolding consists of a platform on which winches are embedded, the platform being suspended from the roof of the construction by cables attached to the inserts on the roof.
- Such a solution is satisfactory when the roof is easily accessible and it is possible to install the cable hooking elements and counterweights necessary for proper operation of the assembly. Otherwise, the operators are poor.
- a scaffolding of the type comprising at least one substantially vertical mast supported on the one hand on a substantially horizontal surface and on the other hand on a substantially vertical surface, the mast serving to anchor the cable of a winch adapted to raising or lowering along the mast a sliding sleeve belonging to a console supporting a work platform.
- the masts are connected by an anchor shown in FIGS 9, this anchor marking the end of the progression in height of the platform and making it impossible to use such a device. scaffolding for work at great heights.
- US-A-3,323,616 consists of a platform moving along two poles formed of modular elements with telescopic interlocking requiring simultaneous assembly or disassembly of the two masts. Again, a sleeve belonging to a console supporting a work platform slides along the mast making it impossible to anchor the mast to a facade and forcing a synchronous movement of the platforms. As this installation can not include means for attachment to a facade, this installation is unsuited to work at high heights.
- Patent FR-A-625,646 describes a scaffolding whose platform is carried by independent masts that can be attached to a facade by means of buttresses. In this case, the platform is formed again of a console and two sleeves each sliding along a mast as shown in Figure 1 of this patent or the passage column 2 - lines 19 to 26 of the description.
- An object of the present invention is therefore to provide a platform support device for the elevation of loads or people along a structure whose design allows to reach any heights and in particular large heights.
- Another object of the present invention is to provide a device of the aforementioned type whose design makes it possible to optimize the assembly and disassembly times of the masts in the case of façades of large width.
- Another object of the present invention is to provide a device of the aforementioned type whose design can cover an entire facade by limiting the number of masts to be used.
- Another object of the present invention is to provide a device of the aforementioned type whose design allows to reuse most of the constituent elements of the device in a traditional suspended platform type mounting.
- the subject of the invention is a platform support device for lifting loads or persons along a structure, particularly for carrying out work applied to said structure, this device comprising, in combination with a platform, lifting elements of the platform winch type to adjust at will the level of elevation of the platform, modular elements assembled forming mast to reach a desired height, the establishment of each mast element being effected from the loading platform connectable to the masts, at least on the one hand, by the winch type lifting elements which can be disconnected at will from said masts, on the other hand, by temporary immobilization means of the platform relative to a modular element of each mast to allow, in the immobilized state of the platform, the addition or the overhead suppression of the masts of at least one modular element according to the at the elevation height of the desired platform, characterized in that each platform is placed between two independent modular masts forming an elevation and guide path, each mast having at least two guideways each capable of cooperating with a platform so as to allow, in particular, the same mast, to be used for the synchronous or asynchronous elevation of two
- the masts being positioned at the ends of the platform which is thus housed in the space left free between said masts, plus any constraint in terms of elevation of the platform form because of the anchoring of the masts to the work is noticeable.

- Figure 13 shows an overview of the safety system slaved to the cable tension in a relaxed position of said cable, ensuring the immobilization of the platform.
- the platform support device 1A, 1B object of the invention, must allow the lifting of people and / or loads at high heights generally of the order of 50 meters or more in order to facilitate, in particular, renovation work on building facades.
- This platform support device must be able to be set up from the ground without having to use the roof of the construction.
- This platform support device comprises, as mentioned above, in combination with a platform 1A or 1B, elements 2, 3 elevators of the winch type platform to adjust at will the level of elevation of the platform 1A, 1B as well as modular elements 4, 6 assemblable forming mast to reach a desired height.
- each mast element 4 is made from the platform 1A, 1B load connectable to the masts. a part by the elements 2, 3 hoist type winches disconnectable at will from said masts, on the other hand by means 5 temporary immobilization of the platform 1A, 1 B with respect to a modular element 4 of each mast hook type.
- the temporary immobilization means 5 it is possible to proceed, at the masthead, to the addition or the suppression of at least one element 4, 6 modular depending on the height of elevation of the platform 1A, 1 B desired.
- the winch 2 is again actuated to allow the platform 1A, 1 to be raised. B until a new temporary immobilization of the platform along the masts and then again, the addition of a new modular element 4 for each mast.
- the operation can be repeated until the desired height is reached.
- the platform can thus be raised to any height by virtue of the fact that the platform 1A, 1B is placed between the two modular masts 16, 17 forming an elevation path.
- the anchoring of the masts 16, 17 to the front of the structure does not prevent such an elevation of the platform.
- the installation is intended to achieve great heights, the number of modular elements to form each mast is relatively important.
- this platform support device 1A, 1B has the advantage of allowing the reuse of most of its elements for the production of a suspended platform. All of these advantages will be developed in more detail below from the detailed description of the platform support device.
- lifting elements 2, 3 consist of at least a winch body 2 embedded on the platform 1A, 1B and a cable 3 extending between mast and platform 1A, 1B. Embodying the winch body 2 on the platform 1A, 1B allows, during disassembly of the platform, to have a platform and a winch ready for use for the realization of a suspended platform.
- the winch body 2 is of the continuous cable passage type of any length to prevent the platform 1A, 1B, under certain conditions, to support the entire weight of the cable 3.
- the winch is not a drum winch in which case the cable is wrapped around the winch body and unrolls or wraps as the platform is raised.
- An example of such a winch continuous cable passage of any length is described in particular in FR-A-2,618,421.
- These winches generally consist of a pulley provided with a grip groove and a cam for locking the cable inside said grip groove. The cable is able to extend beyond this pinching zone and thus tends from the winch as shown in Figure 1 to come to rest on the ground.
- the platform does not have to support the entire weight of the cable as may be the case for installations of the type consisting of drum winch. This solution is therefore particularly interesting in the case of a platform support device whose platform is intended to reach a great height.
- each modular mast element 4 consists of uprights 7, preferably at least four, interconnected by spacers 8 inclined or horizontal to form a lattice structure whose uprights 7 serve in pairs to guide the platform 1A, 1 B during its elevation along said poles 16, 17 while some of the struts 8 of the bar type cooperate with the temporary immobilization means 5 carried by the platform 1A, 1B to immobilize the latter.
- the modular mast element 4 intended to bear against the ground differs from the other modular elements 4 in that it is secured at one of its ends to a support plate 15 on the ground.
- This plate is provided with means for adjusting its attitude to ensure perfect verticality of the mast 16, 17 as and when it is raised.
- Each mast is in the form of an independent mast with respect to another mast. It is therefore self-stable so that a mast 17 can be disassembled without having to disassemble the mast 16 with which it cooperated.
- the masthead element 6 is, in a similar manner to the other modular mast elements 4, provided with uprights intended to be assembled by one of their ends to the modular elements 4.
- the elements 4, 6 of the mast 16, 17 modular are thus nestable through their uprights 7 placed end to end. A necking can be provided to facilitate this nesting. Additional coupling members, such as bolting, between modular mast members 4 may also be provided to enhance the mechanical strength of the assembly.
- the element 6 masthead may consist of two parallel plates interconnected by spacers for constituting the means 13 for hooking the cable on the element 6 masthead.
- tubes for constituting two amounts for the assembly by interlocking the element 6 masthead to other modular elements 4 of the mast.
- the plates extend to form an arm terminated by an open hook in the direction of the sky to be locked under a bar-type spacer
- These arms are offset laterally from a mast head member 6 to another head element 6 to allow the positioning of two masthead elements on the same mast as shown in Figure 4.
- a roller may further be provided at the masthead to facilitate the handling of the mast elements.
- the design of each head element allows a quick and easy positioning of said element.
- this element 6 of masthead is made symmetrical with respect to the median longitudinal plane of the mast to allow in particular the attachment in parallel of at least two cables 3.
- This provision is more particularly interesting when the same mast is used for the elevation in parallel of two platforms which can each have a cable adapted to hook on the element 6 masthead.
- the permanent attachment of the cable to the element 6 of the masthead makes it possible to avoid any error in the handling of the operator who, at each phase of addition or removal at the masthead of a modular element, simply disengaging the masthead element 6 and then bringing or removing a mast element 4 before repositioning the masthead element 6 without have to touch the hooking of the cable 3 on the element 6 of the masthead. This solution increases the security of the whole.
- the poles 16, 17 obtained by assembling modular elements of the aforementioned type are independent, self-stable and self-supporting poles.
- Independent masts are masts of a pair of masts that can be disassembled independently of one another.
- Each mast has a high rigidity due to its embodiment in the form of a beam unlike the scales of the state of the art.
- the embodiment of the masts in the form of a tubular element, the beam being hollow and formed from a lattice structure, makes it possible to reduce the weight of the assembly.
- the poles each preferably comprise at least four uprights 7 connected together by spacers 8 inclined or horizontal.
- the uprights 7 of one and the same mast constitute, in pairs, a path 11, 12 for guiding a platform 1A, 1B.
- a mast made in the form of a tubular element with polygonal section has two faces each serving for guiding and elevating a differentiated platform while at least some of the other faces of the mast held free allow the anchoring the mast to a construction.
- the temporary immobilization means 5 consist of spring-loaded hooks, these hooks forming a pawl retracting during the elevation of the platform 1A, 1B and hooking on the elements 4 of mast during a lowering of the platform 1A, 1 B. These hooks are carried by a plate attached to the base of the platform.
- This plate can be easily removable or retractable to allow the removal of these elements, especially when used in the form of a suspended platform of the platform of the installation.
- the hooks retract automatically and the spring brings them back to a position in which they come to lock on the bars 8 forming a spacer between two mast uprights.
- the hooks are manually retracted between two phases of removal of modular elements 4 mast and are then released to come in a position in which they lock the platform on the masts and thus allow the removal of a mast element.
- the guide means of a platform 1A, 1B along a mast are for example consist of rollers 9, preferably grooved, carried by a support 10 detachably connectable to the platform 1A, 1 B.
- the rollers 9 grooved a support and roll along two uprights 7 of the mast used to form a path 11 or 12 for guiding the mast.
- An embodiment of the guide means is provided in FIG.
- the same platform comprises two supports 10 equipped with rollers 9, each support 10 cooperating with a path 11 or 12 for guiding a mast 16, 17.
- the rollers which form rolling bearing contact members could be replaced by guiding members bearing contact sliding along said posts without departing from the scope of the invention.
- the fact that the support 10 roller holder 9 is coupled by simple bolting to the platform allows easy disassembly of this set again to allow reuse of the platform in the form of suspended platform.
- the mast elements 4 are couplable to the structure along which they are located. arranged in particular by percussion anchoring.
- the operator regularly performs an anchoring of the mast elements to the facade of the construction. It can use for this purpose the spacer elements between mast uprights. It can also use anchor bars fixed at one of their ends to the mast and protruding from the mast by the free surface 13 of the mast to come at their other end to attach to the construction. It is not necessarily necessary to anchor each modular mast element to said facade.
- An anchoring means may be provided every two-three elements.
- an additional safety device secured in displacement of the platform 1A, 1B, adapted to retain the platform 1A, 1B in the support position on the mast in case of breakage of the cable 3 of the winch 2.
- the operation of these safety devices is controlled by the tension of the winch cable. In the relaxed state of the cable, the safety device is active while it is inactive in the tight state of the cable.
- each stop 14 is connected to another stop 14 by an axis 18.
- This axis 18 is itself coupled to a bracket 19 carrying a wheel 20 which delimits with the branches of the yoke a passage of cable 3 of the winch.
- the cable 3 acts in the stretched state on the wheel to cause a displacement of the caliper / stop assembly towards the center of the platform thus preventing the stops 14 to bear on the spacers 8 of the mast bar type.
- the stops move towards the mast and grip a bar 8 thus ensuring the retention of the platform along the poles.
- the platform support device as described above, it becomes easy to reach great heights by means of the platform. In addition, the phases of disassembly and repositioning of the masts along the facade are facilitated. Finally, it is possible to cover the entire facade with such platform support devices by limiting the number of poles to be used. Such a construction therefore has a large number of advantages in view of the state of the art.
