Definitions

  • the present invention relates to a scaffolding module to be used for the realization of a scaffolding structure for construction works such as buildings, infrastructures or monuments.
  • the invention also relates to a method for the assembly/disassembly of a scaffolding structure composed of a plurality of scaffolding modules.
  • the respective assembly procedure specifies the set-up of a plurality of bases fixed or removable and the subsequent positioning of portal frames, each one on a pair of the corresponding bases.
  • the frames are then joined together through the use of diagonal connection bars and rails.
  • a set of anchors for the structure and a set of walkable surface boards that make up the first layer of scaffolding are then prepared.
  • the next phase consists in the outfitting and tightening - always working at ground level - of the so-called "lifelines" that enable the workers to climb in safety onto the scaffolding platform in order to perform the assembly of the elements destined to support the second platform or other alternative elements according to the pre-established construction drawing.
  • operators In order to lift the elements to be assembled portal frame, rails, etc to the desired height, operators have traditionally used electric lifts or cable-pulley systems wherever possible, when scaffolding of modest height was required, for example.
  • the disassembly of this type of scaffolding consists in dismantling from the structure's highest level with the use of a "lifeline".
  • the material is lowered to the ground using the above-mentioned lifting or manual systems. After reaching the structure's lowest level and making sure that they are no longer necessary, the anchors are removed and the material is put away.
  • the assembly process occurs essentially as above.
  • raised tubes are installed if necessary and the H-frames are positioned and connected to the internal rails.
  • the anchors are set up, the railings of the scaffolding's first level are installed, and the boards that form the walkable surface are positioned.
  • the operators usually use a trapdoor with a ladder and then attach themselves to safety systems. After taking steps to ensure their own safety, they continue the assembly process by repeating the above operations for each successive layer required.
  • lifting systems similar to those described above are used to carry the elements to be assembled to the desired height, and the disassembly process is entirely similar to the one described above for portal frame scaffolding structures.
  • the main aim of the invention is to provide a scaffolding module for the assembly/disassembly of a scaffolding structure that overcomes the above problems.
  • one object of the invention is to provide a scaffolding module that reduces the operating costs and times required for the assembly/ disassembly of the scaffolding structure.
  • Another object of the invention is to provide a scaffolding module that permits the use of a scaffolding structure assembly/disassembly method that requires fewer workers while at the same time ensuring the proper safety of such workers.
  • Another object of the invention is to provide a scaffolding module that enables a scaffolding structure assembly/disassembly method to be used such that the scaffolding structure can be erected quickly even when obstructions are encountered.
  • Another, not necessarily last object of the invention is to provide a modular scaffolding structure that is reliable and easy to construct at competitive costs.
  • Additional aspects of the present invention relates to a scaffolding structure assembly/disassembly method according to the following Claims 8 and 9.
  • the scaffolding module according to the invention can be advantageously combined with another equivalent module to form a substantially modular scaffolding structure.
  • centring means facilitates this combination, significantly reducing the human action required, which can in any case be undertaken in safe conditions, as described below.
  • the module according to the invention also enables a scaffolding structure to be assembled/disassembled using an extremely rapid and safe method that also affords significant savings in terms of operating times and costs.
  • the scaffolding module 1, 1B, 1C according to the invention is advantageously employed in the realization of scaffolding structures 2 for construction yards.
  • the module 1, 1B, 1C essentially comprises a plurality of support frames 4, between which at least one walkable surface 5 extends in the longitudinal direction.
  • Each support frame 4 also includes a pair of upper coupling ends 6 and a corresponding pair of lower coupling ends 7. The distance between a lower coupling end 7 and an upper coupling end 6 gives the scaffolding module 1 its vertical definition.
  • FIGS. 1 and 2 show from different points of view a module 1 that can be considered as an "elementary" module for the purposes of this invention.
  • Said module includes two support frames 4 each of which has an essentially "H" shape consisting of two vertical members 4B and a cross member 4C.
  • Each vertical member 4B defines a lower coupling end 7 and a corresponding upper coupling end 6.
  • the cross member 4C supports one end of the walkable platform 5, which can be created using the boards commonly employed in scaffolding construction.
  • the module 1 includes centring means positioned on the upper coupling ends 6 and/or lower coupling ends 7 to facilitate the coupling of the module 1 respectively with the lower 7 or upper 6 coupling ends of another module.
  • the upper coupling ends 6 of the module 1 are in fact destined to be coupled to the lower coupling ends 7 of another module in order to create a modular scaffolding structure 2, see Figure 4 , which in its most basic form comprises two levels, i.e. two walkable surfaces 5, 5' created by placing the two modules 1, 1B one above the other.
  • a first module 1 lends itself to being advantageously lifted over a second module 1B and then lowered so that its two lower coupling ends 7 are coupled to the corresponding upper coupling ends 6' of the second module 1B.
  • the presence of the centring means is extremely advantageous because it guides the coupling of the modules 1, 1B, thereby reducing the need for human action to a minimum.
  • the scaffolding structure 2 may constitute the required scaffolding structure, or it may also simply be a "modular group" consisting of two modules that can be further extended by coupling another module 1C according to the invention.
  • the coupling of another module 1C gives rise to the scaffolding structure 3 shown in Figure 6 , with three walkable surfaces 5, 5B, 5C.
  • the third module 1C is coupled to the "modular group" formed by the two previously-coupled modules in such a way that the lower coupling ends 7C of the third module 1C engage with the upper coupling ends 6 of the first module 1 placed over the second module 1B.
  • each of the stacked modules 1, 1B, 1C includes one or more safety railings 17 that are installed between the members 4B of the module frames 4 before a module is coupled to other modules.
  • these safety railings 17 serve to make the corresponding walkable surface 5, 5B, 5C safe after the structure 2 has been assembled.
  • the safety railings 17 also contribute to stiffening the module and make it easier to lift during the assembly of the structure 2.
  • the safety railings 17 can also be positioned between two sides of two vertical members 4B in the longitudinal direction, in which the module 1, 1B, 1C extends, or they can serve as frontal safety barriers (not shown) supported transversally between two vertical members 4B of the same frame 4.
  • Figures 7 and 7B show perspective views of a preferred embodiment of the centring means for positioning on the lower coupling ends 7 of the first module 1 according to the invention.
  • centring means lie in that they provide a stable support surface 80 for the scaffolding module 1 during its set-up or before it is lifted and coupled on top of another module 1B.
  • this stable support surface is also extremely useful during the disassembly of the structure.
  • dismantling involves a modular disassembly of the structure. After a module has been detached from the structure, it can simply be placed on the ground using these support surfaces.
  • centring means in the solution illustrated consist of centring bowls 8 with truncated cone surfaces 23 with hollow collars 24 in line with the lesser cross-section of the truncated cone surface 23.
  • the collar 24 is coupled to one of the lower coupling ends 7 of the module 1 and fastened thereto by means of locking means 23, such as bolts with nuts.
  • the rim of the bowl 20 corresponding to the larger cross-section of the truncated cone surface 23 provides the stable support surface 80 for the module 1.
  • the centring bowl 20 thus formed becomes a support foot for the module itself.
  • Figure 8 provides an exploded view that best illustrates the type of coupling between the lower coupling end 7 of a first module 1 according to the invention and the upper coupling end 6B of a second module 1B according to the invention.
  • the second module 1B advantageously includes insertion-type coupling means preferably positioned at the upper coupling ends 6B.
  • These coupling means consist of a tapered tube 9 that is inserted inside the upper coupling end of the module 1 so that its tapered end 9B protrudes from the same.
  • the tapered tube 9 is locked to a corresponding end by means of second locking means 13, such as bolts with nuts, for example, or any other functionally equivalent means that enable the coupling to be maintained in a fixed operative position in relation to the upper coupling end 6B in which it has been inserted.
  • second locking means 13 such as bolts with nuts, for example, or any other functionally equivalent means that enable the coupling to be maintained in a fixed operative position in relation to the upper coupling end 6B in which it has been inserted.
  • centring bowl 8 in the example provided decidedly facilitates the coupling of the ends of the two modules 1, 1B. More in detail, the internally hollow truncated cone shape of the centring bowls 8 guides the movement of the lower coupling ends 7 of the first module 1 as they are lowered onto the upper coupling ends 6B of the second module 1B .
  • Figure 9 provides a cross-sectional view with a detailed look into the structure of the coupling between the two modules coupled together from above 1, 1B as previously described.
  • the first module 1 is fitted with locking means that lock the coupled ends together in a removable way.
  • the locking means 33 can advantageously consist of a bolt that transversally passes through the coupling, or rather, the tapered part 9B of the tube 9 and the module lower coupling end 6B , and is locked by a nut on the other end.
  • Other functionally equivalent systems can obviously be used for the same purpose.
  • the scaffolding module 1 features connecting means that can be connected to the lifting equipment on site. These connecting means are preferably positioned on the upper coupling ends 6 in order to ensure more stable movement and especially the more stable lifting of the module as better described below.
  • the invention also relates to a method for the assembly/disassembly of a scaffolding structure 2 that includes a plurality of scaffolding modules 1, 1B, 1C as indicated above.
  • the method according to the invention is characterized by the coupling/uncoupling of a first module 1 to/from a second module 1B in such way that the lower coupling ends 7 of the first module 1 are coupled/uncoupled to/from the corresponding upper coupling ends 6' of the second module 1B.
  • such coupling/uncoupling is performed with the use of lifting equipment.
  • the scaffolding structure 2 is composed through the coupling of modules and then dismantled through modular disassembly. This solution is completely different from the traditional methods based on the assembly and subsequent disassembly of the structure piece by piece.
  • the method according to the invention is extremely advantageous because the modules can all be prepared at ground level and only then coupled together with the use of lifting equipment. As a result, the workers can work substantially from the ground and use the lifting equipment to carry the material, e.g. the scaffolding modules coupled on the ground to the desired height.
  • the lifting equipment may include mechanical lifting arms with much higher lifting load capacities than the traditional electric lifts or cable-pulleys systems.
  • the method according to the invention envisions a preliminary phase with a plurality of scaffolding modules 1, 1B, 1C, which according to the invention might be those shown in Figure 10 for example.
  • the modules shown in this figure consist in five support frames 4 along which a walkable surface 5 extends.
  • a first module 1 is coupled to a second module 1B in order to form the twin-module structure 2B shown in Figure 11 .
  • only one worker is required on the walkable surface 5 of the second module to lock the coupling ends being coupled into position.
  • the presence of the centring means associated with the first module 1 and/or the second module 1B is extremely useful in making said coupling.
  • the twin-module structure 2B shown in Figure 11 can be further developed by repeating the method according to the invention, or in other words, by joining to the same yet another module 1C.
  • FIG. 14 illustrates two such modular groups 2B, 2A, each formed by the insertion from above of two equivalent modules such as the modules 1, 1B, 1C, 1D shown in Figure 13 , or in other words, modules composed of eight support frames 4 and one walkable surface 5 .
  • the two modular groups 2B, 2A shown in Figure 14 can be coupled together or as an alternative, each one can be coupled to another single module 1 of the type shown in Figure 13 in order to obtain the structure 2D shown in Figure 15 , for example.
  • the latter might also be coupled to another equivalent structure or further developed through the coupling of other modules that might or might not be equivalent to the others already used.
  • modules provided for the realization of the modular structure can be equivalent or different.
  • equivalent module is used to indicate a plurality of modules that are substantially equal but sometimes slightly different in terms of the number of sides in the support frame, the number of walkable surfaces, and the respective longitudinal, transversal and vertical dimensions.
  • the structure shown in Figure 16 is obtained by starting from the preparation of three modules, two of which can be considered equivalent, while the third differs from the other two in terms of longitudinal development. In greater detail, this structure is made by coupling one of the modules shown in figure 10 to one of the modular groups shown in Figure 14 .
  • Figure 17 provides a schematic representation of scaffolding structure 2 during its disassembly.
  • the structure is disassembled in modular fashion, in other words through decomposition into modules.
  • the method envisions a preliminary phase that consists in the removal of the locking means that solidly fasten the upper coupling ends of a module coupled to the corresponding lower coupling ends of another module.
  • the modular structure can be advantageously disassembled using the same lifting equipment but with different criteria than those used during the structure's assembly.
  • this possibility consists in the fact that the dismantling of a structure can provide modules or "modular groups" that can be used to assemble another structure. After detachment from the structure, the modules can be easily placed on the ground thanks to the centring means that offer the stable support surface indicated above.
  • the coupling/uncoupling of the scaffolding modules is obtained with the use of lifting equipment, one form of embodiment of which is shown in the figures above, and more precisely, in Figures 11 and 15 for example, in which lifting is preferably performed by connecting the upper coupling ends 6 of the module 1 - which must be connected to the connecting means provided at the ends themselves.
  • the ends must be preferably connected to a web truss 15 that is raised by a mechanical lifting arm 16 such as that of a crane or any other functionally equivalent lifting machine.
  • the ends are connected to the web truss 15 by means of connection elements 18 such as cables or chains, for example.
  • the truss 15 has been selected in such way as to extend sufficiently in both the transversal and longitudinal directions (always assessed in respect to the direction of the longitudinal development of the walkable surfaces of the modules) and to permit the connection elements 18 to be maintained substantially in vertical position during the lifting of the module.
  • the swaying of the scaffolding module is significantly reduced for greater safety and easier coupling with another module.
  • the lifting equipment is connected to a number of upper coupling ends 6 corresponding to twice the number of frames whenever said number of frames is less than three, see Figures 3 and 4 , for example. Whenever instead the number of frames is higher than 3, see Figures 4 , 5 , 6 , 8 , the number of upper coupling ends connected to the lifting equipment corresponding to twice the number of frames from which a fixed value equal to four is subtracted.
  • the scaffolding module permits the assembly and subsequent disassembly of modular scaffolding structures that run in at least two modular directions.
  • Using the assembly/disassembly method permitted by the scaffolding modules reduces assembly times and costs by 50% compared to traditional methods, while the time saved during disassembly amounts to as much as 80%.
